Description

BACKGROUND

1. Technical Field

[0001] The present invention relates to a coin payout device.

2. Related Art

[0002] A coin payout device is, for example, a structural component of a built-in coin processing apparatus in a vending machine. Conventionally, a coin processing apparatus of such a vending machine is used to process coins dropped into the vending machine. The coin processing apparatus includes several structural components such as a coin-identifying device, a coin-receiving device having coin tubes, and a coin payout device. The coin-identifying device identifies the authenticity and denomination of a dropped coin. The coin tubes receive the coins that have been determined to be authentic, according to the denominations of the coins. The coin payout device pays out the coins in the coin tubes as change.

[0003] Conventionally, various proposals have been made with respect to the coin payout device among the above structural components. For example, one of the proposals is described in JP Patent No. 4407996. The structure described in JP Patent No. 4407996 is schematically illustrated in FIGS. 12 and 13. The conventional coin payout device described in this patent includes a payout slide 502 and reciprocal change slides (not shown). The payout slide 502 receives the lowermost coins in the coin tubes in its coin reception holes 511 to 515, respectively. The reciprocal change slides are respectively disposed opposite the coin reception holes 511 to 514 of the payout slide 502. The payout slide 502 and the reciprocal change slides are reciprocally moved back and forth by a payout link 501 coupled to a drive source.

[0004] The payout slide 502 is disposed on a base. During stand-by, the coin reception holes 511 to 514 are closed over the upper surface of the base. Thus, the lowermost coins are not paid out. When the coins are paid out, the payout slide 502 and the reciprocal change slides are moved backward. Further, the coin reception holes 511 to 514 are moved over coin payout holes. Thus, the coins are paid out of the coin payout holes.

[0005] The coin payout device also includes stopper pins 505 that selectively regulate the reciprocal movements of the respective reciprocal change slides. When the coins are not to be paid out, the stopper pins 505 regulate the rearward movements of the respective reciprocal change slides. As a result, the reciprocal change slides are positioned under the lower surfaces of the coin reception holes 511 to 514 to prevent the coins from being paid out.

[0006] Such reciprocal change slides are effective in the case of coins with relatively small diameters, such as 10-yen coins, 50-yen coins, or 100-yen coins. However, in order to handle coins with a large diameter, such as the 500-yen coin, the front-rear length of the reciprocal change slides is increased. As a result, the size of the coin payout device as a whole is increased.

[0007] Thus, the apparatus according to JP Patent No. 44407996 is provided with a rotating change slide 504 that controls the payout of coins from coin reception hole 515 for receiving 500-yen coins. The rotating change slide 504 includes a fixed pivot portion 542 as a center of rotation, a protruding portion 545, a movable pivot portion 543, and a stopper portion 544. The protruding portion 545 is disposed on one end of the rotating change slide 504 and configured to be advanced or withdrawn from under a lower surface of the coin reception hole 515. The movable pivot portion 543 is formed on the protruding portion 545 side of the fixed pivot portion 542, and detachably fitted in a guide groove 622 in the payout link 501. The stopper portion 544 is disposed on the other end of the rotating change slide 504. The stopper portion 544 is abutted on the stopper pins 505 to regulate the rotation of the stopper portion 544.

[0008] When a 500-yen coin is not to be paid out, the stopper portion 544 abuts on the stopper pins 505 to regulate the rotation of the rotating change slide 504. In this state, when the payout link 501 and the payout slide 502 are moved backward, the movable pivot portion 543 is detached from the guide groove 622. As a result, the protruding portion 545 of the rotating change slide 504 protrudes under the lower surface of the coin reception hole 515. In this way, payout of the 500-yen coin is prevented.

[0009] On the other hand, when a 500 coin is to be paid out, the stopper pins 505 are raised by a solenoid, whereby the regulation by the stopper portion 544 is released. Thus, the rotating change slide 504 becomes freely rotatable. In this state, when the payout link 501 and the payout slide 502 are moved backward, the rotating change slide 504 is also rotated about the fixed pivot portion 542 because the movable pivot portion 543 is fitted in the guide groove 622. As a result, the protruding portion 545 is withdrawn to the rear of the coin reception hole 515. Therefore, the lowermost 500-yen coin in the coin reception hole 515 is paid out of the coin payout hole.

[0010] This type of apparatus is associated with the problem of a fraudulent act (prank) in which, for example, someone inserts his hand or a foreign object into the return slot of the vending machine, and presses only the rotating change slide 504 backward by force. In this case, as illustrated in FIG. 12, the stopper portion 544 may be moved under the stopper pins 505 and detached therefrom, whereby the regulation may be released. When only the rotating change slide 504 is thus rotated, the following problem may be caused. That is, if a coin other than a 500-yen coin, which should be received in the coin reception hole 515, is dropped in, and then a return lever is operated, the payout link 501 and the payout slide 502 will be moved backward, as illustrated in FIG. 13. As a result, the 500-yen coins in the coin reception hole 515 are paid out.

[0011] In addition, the movable pivot portion 543 of the rotating change slide 504 may be detached from the guide groove 622. Further, in the state of FIG. 13, the movable pivot portion 543 of the rotating change slide 504 is withdrawn further backward than the backwardly moved position of the payout link 501. Thus, the movable pivot portion 543 fails to be fitted in the guide groove 622 even when the payout link 501 is moved backward. This causes the problem that the 500-yen coins are freely paid out each time the return lever is operated.

SUMMARY

[0012] The present invention was made to solve the technical problem of conventional art. An object of the present invention is to provide a coin payout device capable of effectively preventing or suppressing the over-payout of a large coin by a fraudulent act.

[0013] To solve the above-mentioned problem, a coin payout device in a first embodiment of the present invention includes: a payout link coupled to a drive source and configured to reciprocally move back and forth; a payout slide including a first coin reception hole for receiving a lowermost first coin in a first coin tube receiving the first coin, the payout slide being configured to reciprocally move back and forth following a movement of the payout link; a rotating change slide configured to rotate following the reciprocal movement of the payout link; and a first stopper pin configured to selectively regulate rotation of the rotating change slide. At the time of no-payout of the first coin, payout of the first coin is regulated by causing the rotating change slide to be disposed to face a lower surface of the first coin reception hole by the first stopper pin, whereas at the time of payout of the first coin, the first coin is paid out by releasing the regulation by the first stopper pin so as to withdraw the rotating change slide from under the lower surface of the first coin reception hole. The coin payout device characterized in that: the rotating change slide includes a fixed pivot portion as a center of rotation, a protruding portion positioned on one end side and configured to be advanced or withdrawn from under a lower surface of the first coin reception hole, a movable pivot portion formed on a protruding portion side of the fixed pivot portion and detachably fitted in a guide groove of the payout link, and a stopper portion positioned on an other end side and whose rotation is regulated by being abutted on the first stopper pin; and the stopper portion and the first stopper pin are shaped such that the stopper portion, when abutting on the first stopper pin, is fitted with the first stopper pin.

[0014] The coin payout device in a second embodiment is the coin payout device according to the first embodiment characterized in that: the first stopper pin has a columnar shape; and the stopper portion includes a concave surface abutting on the first stopper pin.

[0015] The coin payout device in a third embodiment is the coin payout device according to the first embodiment characterized in that the stopper portion includes a part abutting on the first stopper pin, and the first stopper pin includes a part abutting on the stopper portion, wherein the parts have meshing shapes.

[0016] The coin payout device in a fourth embodiment is the coin payout device according to the first to third embodiments characterized in that: the payout link includes an abutment portion positioned to the rear of the first coin reception hole of the payout slide and is configured to be moved backward at the time of payout of the first coin; and when the movable pivot portion is detached from the guide groove by the protruding portion of the rotating change slide being pressed backward without the payout link moving backward, the protruding portion abuts on the abutment portion.

[0017] The coin payout device in a fifth embodiment is the coin payout device according to the fourth embodiment characterized in that, when the payout link is moved backward with the protruding portion of the rotating change slide being abutted on the abutment portion of the payout link, the movable pivot portion is fitted in the guide groove.

[0018] The coin payout device in a sixth embodiment is the coin payout device according to the fourth or fifth embodiment characterized in that the rotating change slide includes a cutout portion for preventing the abutment portion from interfering with rotation of the rotating change slide when the regulation by the first stopper pin is released such that the rotating change slide is rotated following the rearward movement of the payout link.

[0019] In the coin payout device in a seventh embodiment, according to any one of the first to sixth embodiments, the payout slide includes a plurality of second coin reception holes configured to receive respectively lowermost second coins in a plurality of second coin tubes for receiving the second coins. The coin payout device further includes: a plurality of reciprocal change slides disposed adjacent to the rotating change slide from left to right and configured to reciprocally move back and forth following the reciprocal movement of the payout link; and a plurality of second stopper pins configured to selectively regulate the reciprocal movement of the reciprocal change slides at the time of no-payout of the second coins. The coin payout device characterized in that: at the time of no-payout of the second coins, payout of the second coins is regulated by causing the change slides to be disposed to face lower surfaces of the second coin reception holes by the second stopper pins, while at the time of payout of the second coins, the second coins are paid out by causing the change slide to be withdrawn from under the lower surfaces of the second coin reception holes by releasing the regulation by the second stopper pins; and the stopper portion of the rotating change slide is positioned between the reciprocal change slides adjacent to each other.

[0020] According to the present invention, when the first coin is paid out by the rotating change slide, the regulation of rotation of the stopper portion by the first stopper pin is released. Then, the payout link is moved backward, whereby the first coin reception hole is moved backward to reach a payout position for the first coin. Meanwhile, by the rearward movement of the payout link, the movable pivot portion is moved along the guide groove, and the rotating change slide is rotated about the fixed axis.

[0021] The rotation of the rotating change slide makes the protruding portion of the rotating change slide rotate backward. Thus, the protruding portion of the rotating change slide is withdrawn from the first coin reception hole. As a result, the first coin reception hole is opened, and the first coin in the first coin reception hole is paid out.

[0022] On the other hand, when the first coin is not paid out by the rotating change slide, rotation of the stopper portion of the rotating change slide is regulated by the first stopper pin. The seventh embodiment includes the reciprocal change slides that pay out another, second coin. In this embodiment, when the payout link is moved backward for the payout of the second coin, the first and second coin reception holes of the payout slide are moved backward to reach a second coin payout position. Meanwhile, rotation of the rotating change slide is regulated. Thus, by the rearward moving force of the payout link, the movable pivot portion of the rotating change slide is detached from the guide groove. At the same time, the rotating change slide still extends at the first coin payout position in stand-by state. Thus, the first coin reception hole that has been moved to the first coin payout position is closed by the rotating change slide. Therefore, the first coin in the first coin reception hole is supported by the rotating change slide and therefore not paid out.

[0023] According to the seventh embodiment, the reciprocal change slides for controlling the payout of the second coin are disposed adjacent to the rotating change slide. In this case, the stopper portion of the rotating change slide is positioned between the reciprocal change slides adjacent to each other. Thus, the size of the apparatus as a whole can be decreased.

[0024] Conventionally, if someone puts his hand or a foreign object through the return slot of the vending machine and forcibly presses the protruding portion of the rotating change slide backward, for example, the stopper portion could be detached from the stopper pin and the regulation could be released. If this happens, a problem may occur in that the coins in the coin reception hole whose payout is controlled by the rotating change slide is fraudulently paid out.

[0025] In the first embodiment of the present invention, the stopper portion and the first stopper pin are shaped such that the stopper portion, when abutting on the first stopper pin, is fitted with the first stopper pin. Thus, the stopper portion is not easily detached from the first stopper pin.

[0026] In the second embodiment of the present invention, the surface of the stopper portion of the rotating change slide abutting on the first stopper pin has a concave shape. Thus, the area of abutment between the cylindrical first stopper pin and the stopper portion of the rotating change slide is increased. As a result, the stopper portion is not easily detached from the first stopper pin.

[0027] In the third embodiment of the present invention, the part of the stopper portion abutting on the first stopper pin, and the part of the first stopper pin abutting on the stopper portion have meshing shapes. For example, the first stopper pin has saw-toothed grooves, while the surface of the stopper portion abutting on the first stopper pin has saw-toothed grooves meshing with the grooves of the first stopper pin. This also makes it difficult for the stopper portion to be detached from the first stopper pin. In this way, the problem of the regulation of rotation of the rotating change slide being released by fraudulent acts can be effectively prevented or suppressed. As a result, over-payout of the first coin can be forestalled.

[0028] Further, in the fourth embodiment of the present invention, the payout link includes an abutment portion positioned to the rear of the first coin reception hole of the payout slide. If the protruding portion of the rotating change slide is pressed backward without the payout link moving backward, and if the movable pivot portion is detached from the guide groove, the protruding portion abuts on the abutment portion. In this way, even when the protruding portion is pressed backward as described above, rotation of only the rotating change slide is limited to the range up to the abutment portion. This also makes it difficult for the stopper portion to be detached from the first stopper pin.

[0029] If the stopper portion is detached from the first stopper pin, the regulation of rotation of the rotating change slide could be released. However, in the fifth embodiment of the present invention, when the payout link is moved backward with the protruding portion of the rotating change slide abutting on the abutment portion of the payout link, the movable pivot portion is fitted in the guide groove. Thus, by the rearward movement of the payout link, the fitting of the movable pivot portion of the rotating change slide with the guide groove of the payout link is automatically returned. In this way, the number of times of over-payout of the first coin can be limited to one.

[0030] In the sixth embodiment of the present invention, the rotating change slide includes the cutout portion for preventing the abutment portion from interfering with rotation of the rotating change slide when the regulation by the first stopper pin is released such that the rotating change slide is rotated following the rearward movement of the payout link. Thus, the problem of the abutment portion adversely affecting the normal first coin payout operation is eliminated.

DETAILED DESCRIPTION

[0032] In the following detailed description, for purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

[0033] In the following, an embodiment of the present invention will be described in detail with reference to the drawings.

[Example 1]

[0034] FIG. 1 is an assembly perspective view of a coin payout device CM according to an example to which the present invention is applied. With reference to FIG. 1, the overall configuration of the coin payout device CM according to the example will be described. The coin payout device CM according to the example is installed in the coin processing apparatus of a vending machine, for example. The coin payout device CM includes a payout link 1, a payout slide 2, a plurality of reciprocal change slides 3, a rotating change slide 4, stopper mechanisms (solenoid mechanisms) 5, and a base 6. The payout link 1 is coupled to a rotating drive source (motor) (not shown). The payout slide 2 is coupled to the payout link 1. The reciprocal change slides 3 and the rotating change slide 4 operate following the movement of the payout link 1. The stopper mechanisms (solenoid mechanisms) 5 regulate the operation of the change slides 3 and 4. The base 6 supports the payout slide 2.

[0035] The payout link 1 includes a first link portion 11 and a second link portion 12. The first link portion 11 extends laterally in a square column shape. The second link portion 12 extends outward from a left end of the first link portion 11 (as viewed in the sheet of FIG. 1, for example). The first link portion 11 includes a laterally extending guide groove 111 in an upper surface thereof. In the guide groove 111, a projection 112A of a payout cam 112 (which is coupled to the rotating drive source) is movably fitted. Thus, as the payout cam 112 is rotated, the payout link 1 reciprocally moves back and forth in a front-rear direction. The first link portion 11 also includes a plurality of slide guide openings 113 each extending in the front-rear direction. In the present example, four slide guide openings 113 are formed laterally at intervals. In the respective slide guide openings 113, the reciprocal change slides 3 are disposed in such a manner as to be movable in the front-rear direction.

[0036] The slide guide openings 113 include their respective holder members (not shown). The holder member holds the reciprocal change slide 3 in the slide guide opening 113 in an engageable and disengageable manner. The holder member normally holds the reciprocal change slide 3. Meanwhile, with respect to rearward moving force of the payout link 1, movement of the reciprocal change slide 3 may be regulated (movement regulation by stopper pins 5A of the stopper mechanism 5 as will be described below). In this case, the holder member is configured to release the held state of the reciprocal change slide 3.

[0037] On a front surface of the first link portion 11, two coupling pins 114 are disposed in a protruding manner. The coupling pins 114 are coupled to coupling holes 23 in the payout slide 2. At the center on the upper surface of the first link portion 11, a support shaft 115 for the payout link 1 is disposed in a protruding manner. The support shaft 115 is supported on an upper cover (not shown) in a back-and-forth movable manner.

[0038] The second link portion 12 includes an upper plate 121 and a lower plate 122, which are spaced apart from each other and formed such that the rotating change slide 4 can enter the gap therebetween. The front surface side of the upper plate 121 and the lower plate 122 is cut out in an arc shape corresponding to an arc surface of a jutting portion 22 of the payout slide 2, which will be described below. In the lower plate 122 of the second link portion 12, a laterally extending guide groove 122A is formed. In the guide groove 122A, a projection 432 of the rotating change slide 4 is fitted, as will be described below. The guide groove 122A is configured to laterally guide the projection 432.

[0039] At a position of the second link portion 12 of the payout link 1 that corresponds to the rear of a coin reception hole 215 of the payout slide 2 for the 500-yen coin, a columnar abutment portion 124 (see FIG. 3) is formed between the upper plate 121 and the lower plate 122. The positional relationship between the abutment portion 124 and the rotating change slide 4 will be described below. Further, at the left-side front end of the lower plate 122, an upwardly extending coupling pin 123 is disposed. The coupling pin 123 is coupled to the coupling hole 24 of the payout slide 2.

[0040] The payout slide 2 is a laterally extending rectangular plate with a plurality of laterally disposed coin reception holes vertically penetrating therethrough. The coin reception holes include, from right to left, 100-yen coin reception holes (second coin reception hole) 211 and 212, a 10-yen coin reception hole (second coin reception hole) 213, a 50-yen coin reception hole (second coin reception hole) 214, and the 500-yen coin reception hole (first coin reception hole) 215, for example. For the 500-yen coin reception hole 215, the arc-shaped jutting portion 22 is formed toward the rear to accommodate the larger coin diameter. The 500-yen coin reception hole 215 extends into the jutting portion 22. As indicated by dashed lines in FIG. 1, the coin reception holes 211 to 215 are in communication with coin tubes 7A to 7E, respectively, for receiving change according to denomination. The coin reception holes 211 to 215 receive the lowermost coins in the coin tubes 7A to 7E, respectively. As described above, the coupling holes 23 and 24 of the payout slide 2 are coupled to the coupling pins 114 and 123 of the payout link 1, respectively. Thus, the payout slide 2 is moved back and forth in a reciprocal manner following the reciprocal movement of the payout link 1.

[0041] The 500-yen coins correspond to a first coin. The coin tube 7E corresponds to a first coin tube. The 10-yen coins, 50-yen coins, and 100-yen coins correspond to a second coin. The coin tubes 7A to 7D correspond to a second coin tube.

[0042] As described above, the reciprocal change slides 3 penetrate the respective slide guide openings 113 in the payout link 1. The reciprocal change slides 3, as illustrated in FIGS. 5 to 7, are disposed opposite the respective coin reception holes 211 to 214. When the payout slide 2 is moved backward, as illustrated in FIG. 7, the reciprocal change slides 3 whose movement is regulated are disposed to face the lower surfaces of the respective coin reception holes 211 to 214.

[0043] Meanwhile, the rotating change slide 4, as illustrated in FIG. 2, includes a rotating arm 41. The rotating arm 41 substantially has the shape of the caret symbol in plan view. The interval between one end (tip end) and the other end

[0044] (rear end) of the rotating arm 41, i.e., the end-to-end portion, is elevated, as illustrated in FIG. 1. On the end-to-end portion, a fixed pivot portion 42 is disposed in a protruding manner. The fixed pivot portion 42 is rotatably axially supported on the upper cover (not shown) and disposed outside of the payout link 1.

[0045] The rotating change slide 4 includes a protruding portion 45 outwardly protruding from a portion on the one end side (tip end side) of the fixed pivot portion 42 of the rotating arm 41. As illustrated in FIG. 4, the protruding portion 45 includes a tapering surface 451 on the front end (tip end) thereof, with a lowering upper surface toward the end. The protruding portion 45 further includes a cutout portion 452 at the rear end. At an outer end portion of the cutout portion 452, an outwardly protruding locking portion 453 is formed (FIG. 2).

[0046] The rotating change slide 4 further includes a movable pivot portion 43 disposed on the protruding portion 45 side of the fixed pivot portion 42 of the rotating arm 41. As illustrated in FIG. 2, the movable pivot portion 43 is formed by cutting the rotating arm 41 in substantially U shape. The movable pivot portion 43 includes a thin elastic piece 431, as illustrated in FIG. 3, which has resilience. As illustrated in FIG. 3, on a tip-end lower surface of the elastic piece 431, a hemispherical projection 432 is disposed in a protruding manner. The projection 432 is detachably fitted in the guide groove 122A of the second link portion 12.

[0047] As illustrated in FIG. 6, when the 500-yen coin is not to be paid out, the protruding portion 45 of the rotating arm 41 on the one end side (tip end side) thereof extends under the lower surface of the coin reception hole 215 from the rear side and is aligned with the front side peripheral edge. Thus, the protruding portion 45 is configured to support the 500-yen coins in the coin reception hole 215.

[0048] On the other hand, the other end side (rear end side) of the rotating arm 41 extends toward the gap between adjacent reciprocal change slides 3, as illustrated in FIGS. 5 to 7. The other end serves as a stopper portion 44. The stopper portion 44 is disposed such that one of the stopper pins 5A of the solenoids 5 abuts on the stopper portion 44. In the present example, the surface of the stopper portion 44 abutting on the stopper pin 5A has a curved concave shape, as illustrated in FIG. 2. Thus, as will be described below, the area of abutment between the cylindrical stopper pin 5A and the stopper portion 44 is increased.

[0049] The stopper mechanisms 5 including the solenoids, as illustrated in FIG. 1, are disposed above stopper portions of the four reciprocal change slides 3 (i.e., rear end surfaces of the respective reciprocal change slides 3) and the stopper portion 44 of the rotating change slide 4. The stopper mechanisms 5, by moving the cylindrical stopper pins 5A vertically, regulate rearward movement of the reciprocal change slides 3 and clockwise rotation of the rotating change slide 4.

[0050] The stopper pin 5A by which clockwise rotation of the rotating change slide 4 is regulated corresponds to a first stopper pin. The stopper pins 5A by which rearward movement of the reciprocal change slides 3 is regulated correspond to a second stopper pin.

[0051] As illustrated in FIG. 1, the base 6 is a rectangular box with open top and bottom. On the front side, a support plate 61 movably supporting the payout slide 2 is disposed. An opening left unclosed by the support plate 61 of the base 6 provides a coin payout hole 62 defining a coin payout position. The base 6 further includes a rear plate 63 with through-holes 64 corresponding to the reciprocal change slides 3. As illustrated in FIG. 6, the reciprocal change slides 3, which are moved backward following the movement of the payout link 1, are guided in the through-hole 64.

[0052] The positional relationship between the abutment portion 124 formed in the second link portion 12 of the payout link 1 and the rotating change slide 4 will be described. The abutment portion 124, when the projection portion 432 of the movable pivot portion 43 of the rotating arm 41 of the rotating change slide 4 is fitted in the guide groove 122A of the payout link 1, is positioned to the rear of the protruding portion 45 positioned on the one end side of the rotating arm 41 of the rotating change slide 4 (FIG. 5).

[0053] From the above state, when the regulation of rotation of the rotating change slide 4 is released by the stopper pin 5A of the stopper mechanism 5, as will be described below, the payout link 1 and the payout slide 2 are moved backward. In this case, the rotating change slide 4 is rotated in clockwise direction without abutting on the abutment portion 124. The abutment portion 124 is accommodated by the cutout portion 452 of the rotating change slide 4. That is, the rotating change slide 4 is configured in such a manner as to be rotatable while avoiding the abutment portion 124 by the cutout portion 452. Thus, the abutment portion 124 is positioned not to interfere with the rotation of the rotating change slide 4 at the time of such normal operation.

[0054] It is now supposed that the protruding portion 45 of the rotating change slide 4 is pressed backward in the state of FIG. 5, without the payout link 1 and the payout slide 2 being moved backward, as will be described below. In this case, i.e., when only the rotating change slide 4 is rotated in clockwise direction, the projection portion 432 of the movable pivot portion 43 of the rotating arm 41 is detached from the guide groove 122A of the payout link 1. The locking portion 453 formed at the rear end of the protruding portion 45 of the rotating arm 41 of the rotating change slide 4 abuts on the front surface of the abutment portion 124. That is, the abutment portion 124 is positioned such that, when only the rotating change slide 4 is rotated and thus the movable pivot portion 43 is detached from the guide groove 122A, the locking portion 453 of the protruding portion 45 abuts on the abutment portion 124.

(Normal operation)

[0055] With reference to FIGS. 5 to 7, a coin payout operation (normal operation) of the coin payout device CM according to the present example with the above-described configuration will be described. First, reference is made to FIG. 5 to describe a stand-by state. In the stand-by state, the coin reception holes 211 to 215 of the payout slide 2 are covered by the support plate 61 of the base 6. Approximately three-fourths of each of the coin reception holes 211 to 215 is closed by the support plate 61. Thus, the coins (lowermost coins in the coin tubes 7A to 7E) received in the coin reception holes 211 to 215 are in a no-payout state.

[0056] When a 50-yen coin is to be paid out from the stand-by state, the solenoid 5 corresponding to the coin reception hole 214 for the 50-yen coin is turned on. That is, the left-end stopper mechanism (solenoid) 5 in FIG. 1 is excited to release the regulation of movement of the corresponding left-end reciprocal change slide 3. The stopper mechanisms 5 corresponding to the other coin reception holes 211 to 213 and 215 remain OFF (non-excited state).

[0057] Then, the rotating drive source (motor) (not shown) is driven to cause the payout link 1 to perform a single back-and-forth reciprocal movement. As the payout link 1 is moved rearward, as illustrated in FIG. 6, the reciprocal change slide 3 corresponding to the 50-yen coin is moved backward. On the other hand, the other reciprocal change slides 3 and the rotating change slide 4 maintain their stand-by state because their movement and rotation are regulated by the stopper pins 5A of the stopper mechanisms 5. Further, the rearward movement of the payout link 1 also causes the payout slide 2 to be moved backward. Thus, the coin reception holes 211 to 215 are moved over the coin payout hole 62.

[0058] By the above-described operation of the change slides 3 and 4 and the payout slide 2, as illustrated in FIG. 6, the coin reception hole 214 corresponding to the 50-yen coin is fully opened over the coin payout hole 62. On the other hand, the other coin reception holes 211 to 213 are closed by the respective reciprocal change slides 3. When the payout slide 2 is moved rearward, the projection 432 of the movable pivot portion 43 is removed out of the guide groove 122A of the payout link 1. Thus, the rotating change slide 4 is maintained in the same state as the stand-by state. In this way, the coin reception hole 215 is closed by the protruding portion 45 at the one end of the rotating arm 41 of the rotating change slide 4 and by the movable pivot portion 43.

[0059] Thus, only the 50-yen coin in the fully opened coin reception hole 214 is paid out into the return slot of the vending machine as change. When a 10-yen coin or a 100-yen coin is to be paid out, the stopper mechanisms 5 corresponding to the coin to be paid out is turned on, whereby a payout operation similar to the one for the 50-yen coin described above is performed. As a result, the 10-yen coin or the 100-yen coin is paid out as change.

[0060] Next, with reference to FIG. 7, a case where a 500-yen coin is paid out will be described. When a 500-yen coin is paid out, the stopper mechanism 5 corresponding to the coin reception hole 215 for the 500-yen coin is turned on. That is, the second stopper mechanism 5 from left in FIG. 1 is excited to release the regulation of rotation of the rotating change slide 4. Meanwhile, the stopper mechanisms 5 corresponding to the other coin reception holes 211 to 214 remain OFF (non-excited state).

[0061] Then, the rotating drive source (motor) (not shown) is driven to cause the payout link 1 to perform a single back-and-forth reciprocal movement. By the rearward movement of the payout link 1, the projection 432 of the movable pivot portion 43 is moved along the guide groove 122A. As a result, as illustrated in FIG. 7, the rotating change slide 4 is rotated in clockwise direction about the fixed pivot portion 42. In this case, the rotating change slide 4 rotates while avoiding the abutment portion 124 by the cutout portion 452. Thus, the rotating change slide 4 can be rotated without any problem following the rearward movement of the payout link 1.

[0062] On the other hand, the reciprocal change slides 3 maintain their stand-by state as their movement is regulated by the stopper pins 5A of the stopper mechanisms 5, as illustrated in FIG. 7. Further, the rearward movement of the payout link 1 also causes the payout slide 2 to be moved backward. As a result, the coin reception holes 211 to 215 are moved over the coin payout hole 62.

[0063] By the above-described operation of the change slides 3 and 4 and the payout slide 2, as illustrated in FIG. 7, the coin reception hole 215 corresponding to the 500-yen coin is fully opened over the coin payout hole 62. Meanwhile, the other coin reception holes 211 to 214 are closed by the respective reciprocal change slides 3. Thus, only the 500-yen coin in the fully opened coin reception hole 215 is paid out as change.

[0064] In the coin payout device CM according to the example, as described above, the rotating arm 41 of the rotating change slide 4 extends toward the gap between adjacent reciprocal change slides 3, as illustrated in FIGS. 5 to 7. Further, the other end (rear end) of the rotating arm 41 serves as the stopper portion 44. The stopper portion 44 is disposed such that one of the stopper pins 5A of the stopper mechanisms 5 abuts on the stopper portion 44.

[0065] Thus, as illustrated in FIGS. 5 to 7, the stopper pin 5A for regulating the rotation of the rotating change slide 4 can be disposed at the second position from left, i.e., between the stopper pins 5A and 5A for regulating the movement of the reciprocal change slides 3 (more specifically, between the reciprocal change slide 3 corresponding to the 10-yen coin reception hole 213 and the reciprocal change slide 3 corresponding to the 50-yen coin reception hole 214). Thus, as illustrated in FIG. 1, the space in which to arrange the stopper mechanisms 5 of the stopper pins 5A in the left-right direction can be decreased. Further, all of the stopper mechanisms 5 can be disposed along a lateral straight line. Accordingly, compared with conventional coin payout devices, the front-rear length of the apparatus can also be decreased.

[0066] As described above, the rotating change slide 4 includes the rotating arm 41 that rotates about the fixed pivot portion 42. The rotating change slide 4 includes the movable pivot portion 43 on the tip end side thereof that fits into the guide groove 122A of the payout link 1. Thus, the rotating change slide 4 has a simple structure compared with the rotating change slide of conventional coin payout devices.

[0067] Further, as illustrated in FIG. 5, when the 500-yen coin is not to be paid out, the one end (tip end) side of the rotating arm 41 extends from the rear side of the coin reception hole 215 until the arm is along (or aligned with) the front side peripheral edge of the coin reception hole 215. Thus, the 500-yen coin is supported throughout the front-rear direction thereof in the coin reception hole 215. As a result, problems such as the 500-yen coin standing up, for example, can be prevented or suppressed. The protruding portion 45 of the rotating change slide 4 includes the tapering surface 451 with lowering upper surface toward the tip end. Thus, when the 500-yen coin corresponding to the rotating change slide 4 is not to be paid out (when the 10 yen, 50 yen, or 100-yen coin corresponding to the reciprocal change slides 3 is paid out), the lowermost 500-yen coin, which moves over the rotating change slide 4, can be smoothly guided along the tapering surface 451. In this respect too, the problem of the 500-yen coin standing up, for example, can be prevented.

(In case of fraudulent act)

[0068] Next, with reference to FIGS. 8 to 10, operation in a case where a fraudulent act is conducted on the rotating change slide 4 will be described. In the Figures, illustration of portions that are not relevant to the operation of the rotating change slide 4 is omitted. It is now supposed that, in the stand-by state of FIG. 5, someone puts his hand or a foreign object through the return slot of the vending machine, and, with the payout link 1 being unable to be moved backward, forcibly presses backward the protruding portion 45 on the one end of the rotating change slide 4. In this case, only the rotating change slide 4 would rotate in clockwise direction in the Figures. In this case, the second stopper mechanism 5 from left is OFF and thus in non-excited state. Accordingly, the stopper portion 44 on the other end of the rotating change slide 4 is pressed against the stopper pin 5A.

[0069] However, in the present example, as described above, the surface of the stopper portion 44 abutting on the stopper pin 5A has a concave shape, so that the area of contact between this surface and the stopper pin 5A, which is cylindrical, is increased. Thus, the abutment between the stopper portion 44 and the stopper pin 5A is not easily released, and therefore the stopper portion 44 is not easily detached from the stopper pin 5A.

[0070] It is further assumed that, in this state where the other end of the stopper portion 44 is abutting on the stopper pins 5A, the protruding portion 45 on the one end is further pressed backward with even greater force. In this case, only the protruding portion 45 is deformed backward due to the elasticity of the rotating change slide 4. As a result, as described above, the projection portion 432 of the movable pivot portion 43 is removed out of the guide groove 122A. Eventually, the locking portion 453 at the rear end of the protruding portion 45 abuts on the front surface of the abutment portion 124 of the payout link 1, as illustrated in FIG. 8.

[0071] Thus, when the protruding portion 45 of the rotating change slide 4 is pressed backward without the payout link 1 moving backward, and the movable pivot portion 43 is detached from the guide groove 122A, the locking portion 453 at the rear end of the protruding portion 45 abuts on the abutment portion 124 of the payout link 1. Accordingly, when the protruding portion 45 is moved backward, the range of rotation of only the rotating change slide 4 is limited up to the abutment portion 124. This also makes it difficult for the stopper portion 44 to be detached from the stopper pin 5A.

[0072] However, the protruding portion 45 of the rotating change slide 4 could be pressed backward continuously and with even greater force, until eventually the stopper portion 44 is detached from the stopper pin 5A, as illustrated in FIG. 9. In this state, the stopper portion 44 on the other end of the rotating change slide 4 enters under the stopper pin 5A. However, the locking portion 453 of the protruding portion 45 is abutting on the abutment portion 124, whereby the rotation of the rotating change slide 4 is limited. As a result, the rotating change slide 4 is prevented from being greatly rotated backward beyond the payout link 1.

[0073] Thus, when the payout link 1 is moved backward by the rotating drive source, with the locking portion 453 of the protruding portion 45 of the rotating change slide 4 abutting on the abutment portion 124 of the payout link 1, the projection portion 432 of the movable pivot portion 43 can be easily fitted in the guide groove 122A of the payout link 1, as illustrated in FIG. 10. In this way, as the payout link 1 is moved rearward, the fitting between the projection portion 432 of the movable pivot portion 43 of the rotating change slide 4 and the guide groove 122A of the payout link 1 is automatically returned. Although the 500-yen coin may be overly paid out once, the number of times of such over-payout is limited to just one. Subsequently, the rotating change slide 4 returns to stand-by state.

[0074] As described above in detail, according to the present example, the surface of the stopper portion 44 of the rotating change slide 4 abutting on the stopper pin 5A has a concave shape. Thus, the area of abutment between the cylindrical stopper pin 5A and the stopper portion 44 of the rotating change slide 4 is increased. As a result, the stopper portion 44 is not easily detached from the stopper pin 5A. In this way, the problem of the regulation of rotation of the rotating change slide 4 being released by the rotating change slide 4 being fraudulently pressed can be effectively prevented or suppressed. Accordingly, over-payout of coins can be forestalled.

[0075] The payout link 1 is fitted with the abutment portion 124 disposed to the rear of the coin reception hole 215 of the payout slide 2. When the protruding portion 45 of the rotating change slide 4 is moved backward without backward movement of the payout link 1, the projection portion 432 of the movable pivot portion 43 may be detached from the guide groove 122A. In this case, the locking portion 453 at the rear end of the protruding portion 45 abuts on the abutment portion 124. Thus, even if the protruding portion 45 is pressed backward fraudulently, the rotation of only the rotating change slide 4 is limited to the range up to the abutment portion 124. This also makes it difficult for the stopper portion 44 to be detached from the stopper pin 5A.

[0076] The stopper portion 44 could be detached from the stopper pin 5A, thereby releasing the regulation of rotation of the rotating change slide 4. However, when the locking portion 453 of the protruding portion 45 of the rotating change slide 4 is abutted on the abutment portion 124 of the payout link 1, as the payout link 1 is moved backward, the projection portion 432 of the movable pivot portion 43 fits into the guide groove 122A. Thus, by the rearward movement of the payout link 1, the fitting of the projection portion 432 of the movable pivot portion 43 of the rotating change slide 4 with the guide groove 122A of the payout link 1 automatically returns. In this way, the number of times of over-payout of the 500-yen coin can be limited to one.

[0077] On the other hand, when the regulation by the stopper pin 5A is released, and the rotating change slide 4 is rotated following the rearward movement of the payout link 1, the abutment portion 124 does not interfere with rotation of the rotating change slide 4. Thus, the problem of the abutment portion 124 adversely affecting the normal payout operation for the 500-yen coin is not caused.

[Example 2]

[0078] FIG. 11 illustrates the stopper portion 44 of the rotating change slide 4, and the structure of the stopper pin 5A according to another example. In this example too, the stopper portion 44 has a generally concave shape. In addition, the stopper portion 44 includes saw-toothed grooves 44A. On the other hand, the stopper pin 5A has saw-toothed grooves 55A with a shape meshing with the grooves 44A of the stopper portion 44. The grooves 44A of the rotating change slide 4 are configured to mesh with the grooves 55A of the stopper pin 5A when the stopper portion 44 and the stopper pin 5A are abutted on each other.

[0079] Thus, the part of the stopper portion 44 abutting on the stopper pin 5A and the part of the stopper pin 5A abutting on the stopper portion 44 may have meshing shapes, such as the grooves 44A and grooves 55A. In this way, the stopper portion 44 is made more difficult to be detached from the stopper pin 5A. Thus, the problem of the regulation of rotation of the rotating change slide 4 being released by a fraudulent act as described above can be more effectively prevented or suppressed. As a result, over-payout of coins can be forestalled.

[0080] In the present example, the grooves 44A are formed in the stopper portion 44 of concave shape. However, this is not a limitation, and the grooves may be formed in a flat stopper portion 44, with meshing grooves formed in the stopper pin 5A. In this configuration too, a sufficient effect of making the stopper portion 44 difficult to become detached from the stopper pin 5A can be achieved.

[0081] That is, the stopper portion 44 and the stopper pin 5A are shaped such that the stopper portion 44, when abutting on the stopper pin 5A, is fitted with the stopper pin 5A.

[0082] In addition to the structures according to the foregoing examples, the length of the stopper pin 5A may be increased. In this way, the stopper portion 44 can be made more difficult to be detached under the stopper pin 5A. Thus, the effect of making the stopper portion 44 difficult to become detached from the stopper pin 5A can be enhanced. In the foregoing examples, the present invention has been described with reference to the coin payout device of the coin processing apparatus of a vending machine. However, this is not a limitation, and the present invention may be effectively implemented in the coin payout device of coin processing apparatuses for various uses.

[0083] In the examples, the hard currency used is denominated in yen. However, this is not a limitation, and the present invention may be adapted for hard currency used in various countries of the world (such as pound coins, penny coins, euro coins, and cent coins).

[0084] The coin payout device according to the present invention may include any of the following first to sixth coin payout devices. A first coin payout device includes a payout link coupled to a drive source and configured to reciprocally move back and forth; a payout slide including a coin reception hole for receiving a lowermost coin in a coin tube configured to receive the coin and to reciprocally move back and forth following the movement of the payout link; a rotating change slide configured to rotate following the reciprocal movement of the payout link; and a cylindrical stopper pin configured to selectively regulate rotation of the rotating change slide, wherein, at the time of no-payout of the coin, coin payout is regulated by causing the rotating change slide to be disposed to face a lower surface of the coin reception hole by the stopper pin, whereas at the time of payout of the coin, the coin is paid out by releasing the regulation by the stopper pin so as to withdraw the rotating change slide from the lower surface of the coin reception hole, the coin payout device characterized in that: the rotating change slide includes a fixed pivot portion as a center of rotation, a protruding portion positioned on one end side and configured to be advanced or withdrawn from under the lower surface of the coin reception hole, a movable pivot portion formed on a protruding portion side of the fixed pivot portion and configured to detachably fit in a guide groove of the payout link, and a stopper portion positioned on an other end side and whose rotation is regulated by being abutted on the stopper pin; and that the stopper portion includes a concave surface abutting on the stopper pin.

[0087] A fourth coin payout device is the third coin payout device characterized in that, when the payout link is moved backward with the protruding portion of the rotating change slide abutting on the abutment portion of the payout link, the movable pivot portion is fitted in the guide groove.
