2. Description of related art
[0002] With the advancement of technologies, the vending machines installed in the public
places for providing convenience and prompt service to the public, for example, tickets,
coin exchange and so on. Vending machines are not only advantageous for cutting down
the labor cost but also highly acceptable because of the convenience provided. Generally,
the vending machine is unsupervised at most of time except during maintenance or refilling
the merchandize supplies therein. During unsupervised period of time, users may try
to steal the money within the vending machine. Sometimes, some users may exchange
coins or retrieve cards or tickets from the vending machines without actually paying
for it. One common way of stealing is to attach a string or attach a soft long strip
of film to a distal end of the banknote and then insert the banknote into the banknote
entrance slot, and after the transaction of the deal is successful, the user pulls
out the banknote by pulling the string or the long strip of film attached to the distal
end of the banknote. Accordingly, the stealing activity could cause an unimaginable
loss to the vending machines owners.
[0003] To prevent the above loss, the conventional banknote-validating machine is equipped
with a frame
A. Referring to Fig.
9, a cross sectional side view of a conventional banknote-validating machine is shown.
The frame
A has a bill entrance slot
A1 at a side thereof, and inside the frame
A, a circuit board
B for identifying the banknote and a roller set are set at an upper and a lower side
of the banknote channel respectively. A hook
D is set at the exit
A2 of the banknote channel for preventing the banknote from being pulled out after the
banknote enters the banknote entrance slot
A1. However, because the banknote is soft, and therefore when it is forcibly pulled,
the banknote could get easily damaged and also this could jam the banknote entrance
slot and breakdown the vending machine. Further, the abovementioned security function
is effective when the user use a hard material, for example, steel string or a metallic
plate, or a strip of soft film such as an adhesive tape, a thin cardboard, a film
or the like, to pull the banknote. Therefore, the above conventional security has
several defects, and how to improve the banknote-validating machine with better security
has become the important issue for the manufacturers of this industry.
[0004] In a banknote-validating machine equipped with security device according to the first
paragraph of this specification (
US-B-6 349 810), a sensor is provided for judging the authenticity of the inserted paper currency
and its value. If the inserted paper currency is pulled backwards by a cord, a tape,
a steelier or any of a variety of external objects, the accepted paper currency apparently
by pure mechanical action of the corresponding parts is stop from backward movement
by forward producing plates.
[0005] The object of the present invention is to choose a simple and cheap sensor and effective
means for preventing that the banknote is pulled back.
[0006] This object is solved in that said sensor is adapted for sensing a length of a banknote
and a time taken for said banknote to pass through said banknote channel and security
plate comprises a plurality of arrow shaped hooks.
[0007] Thus, contrary to this state of the art sensor is provided which detects irregularities
of the transport of the banknote which are caused by efforts to pull the banknote
back. By the plurality of error shaped hooks it is effectively prevented that the
banknote can be pulled back.
[0008] According to another aspect of the present invention, the plurality of arrow shaped
long and short hooks, and the long and short hooks are arranged alternately.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0019] Reference will be made in detail to the preferred embodiments of the invention, examples
of which are illustrated in the accompanying drawings. Wherever possible, the same
reference numbers are used in the drawings and the description to refer to the same
or like parts.
[0020] Referring to Figs.
1, 2, 3 and
4, an elevational view, an exploded view, a back elevational view and a back exploded
view of banknote-validating machine equipped with security device according to an
embodiment of the present invention, are respectively shown. The banknote-validating
machine comprises a front panel
1, a banknote receiver
2 and a security device
3. The front panel
1 comprises a banknote entrance slot
11.
[0021] The banknote receiver
2 comprises an upper chassis
21 and a lower chassis
22. A banknote channel
23 is formed in between the upper chassis
21 and the lower chassis
22. The upper chassis
21 comprises an upper channel
211. Pluralities of rollers
2111 and sensors
2112 are disposed at a lower portion of the upper channel
211. A plurality of moveable buckling plates
212 is disposed at a side of the upper channel
211. The lower chassis
22 comprises a lower channel
221. A plurality of transporting belt
2211 is disposed on a top of the lower channel
221 and a plurality of buckling holes
222 at a side thereof.
[0022] The security device
3 comprises a chassis
31 having a plurality of moveable directing rollers
311. A security plate
32 having a plurality of hooks
321 is set beneath the directing roller
311.
[0023] The banknote receiver
2 is conjoined by the upper chassis
21 and the lower chassis
22. The upper channel
211 of the upper chassis
21 and the lower channel
221 of the lower chassis
22 constitute the banknote channel
23. The distal end of the banknote channel
23 is conjoint to the inner part of the banknote entrance slot
11 on the front panel
1. The banknote channel comprises sensor
2112, a circuit layout of which is shown in Fig.
8. The sensor
2112 is adapted for detecting whether or not the entrance of the banknote
4 is under normal condition. The upper chassis
21 positioned at the primal end of the banknote channel
23 comprises a plurality of buckling plates
212 to buckle to the corresponding plurality of buckling holes
222. At the location where the buckling plates
212 buckle to the buckling holes
222, a security device
3 having the directing roller
311 is positioned beneath the buckling plates
212 and the buckling holes
222. The security plate
32 is set below the directing roller
311 to substantially secure the banknote
4 inside the banknote-validating machine.
[0024] When a user attaches a long soft strip of film, for example, an adhesive tape, a
thin strip of cardboard, a strip of film, and so on, on the banknote
4 and insert into the banknote channel
211, the aforementioned circuit of the sensor
2112 senses the time taken for the banknote
4 passing the plurality of buckling plate
212 and the buckling holes
222, and if the time for banknote
4 to pass thereof exceed the preset standard value, the circuit of the sensor
2112 issues a signal to reject the banknote
4 and the banknote
4 is ejected out of the banknote entrance slot
11 through the banknote channel
23.
[0025] Alternatively, the circuit of the sensor
2112 senses the number of rotation of the roller
2111 while the banknote
4 passes in the banknote channel
23, and if the number of rotations exceeds a preset standard value, the circuit of the
sensor
2112 issues a command to reject the banknote
4 and the banknote is ejected out of the banknote entrance through the banknote channel
23.
[0026] The security plate
32 of the security device
3 comprises a plurality of hooks
321 arranged in an array comprised of long and short hooks that are alternately arranged.
The hooks
321 have an arrow shape. Therefore, the gaps between the hooks
321 are small and therefore the hooks
321 are capable of preventing the banknote
4 being pulled back by any attached objects.
[0027] Referring to Figs.
4, 5 and
6, a back exploded view, a sectional side view and a sectional side view of a banknote-validating
machine equipped with security device respectively showing while a banknote reaches
the roller, according to an embodiment of the present invention. When inserting the
banknote
4 into the banknote-validating machine of the present invention, the banknote
4 enters to the banknote channel
23 from the banknote entrance slot
11 on the front panel
1. Next, the sensor
2112 set inside the banknote channel
23 senses banknote
4. The banknote
4 is clamped and transported by the roller
2111 and the transporting belt
2211 within the banknote channel
23. Meanwhile, the plurality of buckling plates
212 is lifted up and released from the corresponding plurality of buckling holes
222. The sensor
2112 senses the time taken or the number of rotations of the roller
2111 for the banknote 4 to pass thereby, and if the time taken or the number of rotations
of the roller
2111 for the banknote
4 thereby is found to match with a preset value, the banknote
4 is allowed to pass between the plurality of buckling plates
212 and the plurality of buckling holes
222 as shown in Figs.
6 and
7. On the other hand, if the banknote
4 carries any object attached, after the banknote
4 passes between the plurality of buckling plates
212 and the plurality of buckling holes
222, the directing roller
311 of the security device
3 clamps and forces the banknote channel
23 to form a vertical path to make the banknote
4 pass by the security plate
32 positioned beneath the directing roller
311. Meanwhile, the plurality of hooks
321 of the security plate
32 forms a barricade to block the banknote
4 in order to prevent the banknote
4 from being pulled back by the attached object.
[0028] Referring to Figs.
5, 6 and
7, a sectional side view, a sectional side view showing while a banknote reaches the
roller and a sectional side view showing while a banknote reaches the security plate,
within a banknote-validating machine equipped with security device according to an
embodiment of the present invention. When the banknote
4 enters into the banknote channel
23 of the banknote receiver
2, the sensor
2112 senses the time taken or counts the number of rotations of the roller
2111, for the banknote
4 beginning from the banknote
4 entering the banknote entrance slot
11 until the banknote
4 passes between the plurality of buckling plates
212 and the buckling holes
222. If the sensor
2112 senses that the time taken or the number of rotations of the roller
2111 does not match with the preset value, the banknote
4 will be ejected out of the banknote entrance slot
11 through the banknote channel
23. After the banknote
4 passes the sensor
2112 and reaches the directing rollers
311, the plurality of arrow shaped hooks 321 of the of the security plate
32 can block the banknote 4 from being pulled out from the security plate
32. Thus the dual security functions described above could effectively prevent the banknote
4 in the banknote channel
23 from being pulled out, and also damage to the banknote
4 by any external force can be effectively avoided.
[0029] Furthermore, if a user glues a plastic or soft strip, or ties a string to one end
of the banknote
4, the sensor
2112 is capable of sensing such abnormal situation and reject the banknote
4 and ejects out the banknote
4 out of the banknote receiver
2. In the meantime, the plurality of buckling plates
212 is not released from the buckling holes
222 in order to block the banknote
4. And, when the banknote
4 passes the security plate
32, the attached object will get stuck between the plurality of hooks
321 of the security plate
32, and when the banknote
4 is pulled out by an external force, the hooks
321 cuts off or breaks the attached object. Thus, stealing of the accepted banknote can
be effectively prevented.
[0030] The aforementioned banknote-validating machine equipped with security device of the
present invention has at least the following advantages:
- i) The banknote channel has the sensor and the plurality of buckling plates alternately
positioned with the plurality of buckling holes form the first security pass, and
the second security pass ensure the banknote against being pulled out by the external
force after the banknote enters the banknote channel.
- ii) After the banknote inside the banknote channel of the bank-validating machine
pass the plurality of buckling plates and buckling holes moving in a downward direction
towards the directing roller, the directing roller forces the banknote to move vertically
down and thereby making it increasingly difficult to pull out the banknote by the
external force.
- iii) The security plate of the security device comprises the plurality of arrow shaped
hooks comprised of alternately arranged long-and-short hooks having a small gap there-between
in order to effectively block the banknote.
