BACKGROUND OF THE INVENTION
1. The field of the invention
[0001] The present invention is generally related to a banknote-validating machine equipped
with security device, and more particularly to a banknote-validating machine equipped
with security device having multiple security passes set inside the banknote channel
of the banknote receiver capable of substantially preventing the banknote from being
pulled out by an external force.
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 show.
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
C 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
A1 and breakdown the vending machine. Further, the abovementioned security function
will lose its effectiveness 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.
SUMMARY OF THE INVENTION
[0004] Accordingly, in the view of the foregoing, the present inventor makes a detailed
study of related art to evaluate and consider, and uses years of accumulated experience
in this field, and through several experiments, to create a new security device of
a banknote-validating machine. The present invention provides an innovated cost effective
security device of a banknote-validating machine.
[0005] According to an aspect of the present invention, the banknote-validating machine
comprises a banknote receiver and a security device installed inside the banknote
receiver. The banknote receiver comprises an upper chassis and a lower chassis, and
a banknote channel is formed between the upper chassis and the lower chassis. The
distal end of the banknote channel is conjoint to the inner part of the banknote entrance
on a front panel. A sensor is positioned at a primal end of the banknote channel.
A security plate is positioned at the upper chassis. The sensor is adapted for sensing
the length of the banknote entering banknote channel and the time taken for the banknote
to pass the banknote channel. The security plate is adapted for blocking the banknote.
Thus, the security device has multiple security functions for effectively preventing
the banknote from being pulled out by an external force.
[0006] According to another aspect of the present invention, the sensor installed in the
upper chassis is adapted for sensing the length of the banknote, and if the banknote
exceeds the standard length, the sensor is capable of issuing a signal for ejecting
the banknote out of the banknote entrance slot of the banknote-validating machine.

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 between the upper chassis
21 and the lower chassis
22. An upper channel
211 disposed at a lower portion of the upper chassis
21 comprises pluralities of rollers
2111 and sensors
2112. A plurality of moveable buckling plates 212 is disposed at a side of the upper channel
211. A lower channel
221 disposed on a top of the lower chassis
22 comprises a plurality of transporting belt
2211 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, the 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 film, and so on, on the banknote
4 and insert into the banknote channel
23, 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 signal to reject the banknote
4 and the banknote is ejected out of the banknote entrance slot
11 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 cross sectional side view and a cross sectional side view
showing while a banknote reaches the roller within a banknote-validating machine equipped
with security device respectively 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 the 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 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 cross sectional side view, a cross sectional side view showing while a banknote
reaches the roller and a cross 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 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 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 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 of the securing plate 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.
[0031] While the invention has been described in conjunction with a specific best mode,
it is to be understood that many alternatives, modifications, and variations will
be apparent to those skilled in the art in light of the foregoing description. Accordingly,
it is intended to embrace all such alternatives, modifications, and variations in
which fall within the spirit and scope of the included claims. All matters set forth
herein or shown in the accompanying drawings are to be interpreted in an illustrative
and non-limiting sense.
