Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preventing the withdrawal of banknotes, etc., and particularly to a method for preventing the withdrawal of banknotes, etc. due to fraudulent acts in a banknote processing device such as a vending machine or a money changer.

[Conventional technology]

Generally, a vending machine or a currency exchange machine is equipped with a banknote identification device that identifies whether inserted banknotes are genuine or fake, and a banknote stacking device that stores only the genuine banknotes inserted into a storage box. The banknotes are fed into the banknote collection box from the insertion slot along the banknote path by means such as a conveyor belt, during which time it is determined whether the banknotes are genuine or counterfeit banknotes. In order to prevent genuine banknotes that have passed through the recognition device from being pulled back toward the banknote insertion slot by fraudulent means, a shutter plate is provided in the banknote path to block the banknote path.

[Problem to be solved by the invention]

However, in the above-described conventional method, there is a problem in that a thin elongated celluloid plate or the like is inserted into the banknote passage through the banknote insertion slot, and the shutter plate is artificially retracted to remove the banknote.

Therefore, the object of the present invention is to provide a method for preventing banknotes from being pulled out by driving a stack motor to push banknotes into a stacking box when a thin celluloid plate is inserted from a banknote insertion slot along a banknote path. Our goal is to provide the following.

[Means to solve the problem]

In order to achieve the above object, the method for preventing the withdrawal of banknotes, etc. according to the present invention identifies whether the banknotes inserted from the banknote insertion slot are genuine or false, conveys only the genuine banknotes through the banknote passage to the banknote stacking position, and the banknotes are removed from the shutter. When the shutter switch is turned on after passing through the plate and withdrawal prevention lever, the eccentric cam of the stacker device is rotated to push the bill into the stacking box and hold the eccentric cam at the top dead center position. This is a characteristic feature.

Furthermore, another method of the present invention distinguishes whether the banknotes inserted from the banknote insertion slot are genuine or false, and conveys only the genuine banknotes through a banknote path to a banknote stacking position, and the banknotes pass through a withdrawal prevention lever to prevent eccentricity of the stacker device. This is characterized in that a genuine bill signal is output after the cam is driven and the bill is pushed into the accumulating box.

[For production]

According to the present invention, after genuine banknotes are conveyed through the banknote path to the banknote stacking position, the shutter plate is artificially retracted and when the shutter switch is turned ON, the eccentric cam of the stacker device is rotated to stack the banknotes. can be pushed into the accumulation box to hold the eccentric cam at the top dead center position.

In addition, according to another method of the present invention, since the genuine bill signal is output after the bill passes the withdrawal prevention lever, even if the fraudster tries to pull the bill back toward the bill insertion slot, the bill will not be removed. can be caught on the pull-out prevention lever and prevented from being pulled out.

is closed.

Therefore, the shutter plate 28 is pushed by the banknotes B moving in the banknote receiving direction and automatically retreats to the outside of the passage to turn on the shutter switch, and functions as a stopper for banknotes moving in the opposite direction.

A banknote withdrawal prevention device 32 is provided below the bottom plate 31 of the stacking box 24. As shown in FIG. 2, this pull-out prevention device 32 includes a bracket plate 33, a pull-out prevention lever 34, and a pivot shaft 35 that connects the two. The bracket plate 33 is attached to ear pieces 33a, 33a, and a U-shaped bracket body 33b with an upper opening that integrally connects these pieces.
It consists of Further, the pull-out prevention lever 34 is

They are connected together by a connecting plate 38, and a tongue piece 39 is provided at the center of the connecting plate 38.
has been erected. The pull-out prevention lever 34 is pivoted so as to be rotatable around a pivot shaft 35. A coil spring 40 is mounted on the pivot shaft 35, and the pull-out prevention lever 34 is moved by the spring force of the coil spring 40. In FIG. 1, a claw member 36 is spring-biased around a pivot shaft 35 in a direction that blocks the banknote passage 5. As shown in FIG.

In addition, in FIG. 1, immediately after the bill insertion slot 2, there is a occupancy sensor 41 for detecting that a bill is inserted.
, and numeral 42 is a stacker switch for detecting whether or not the collection box 24 is set at a predetermined position.

Next, the procedure for preventing banknotes from being pulled out will be explained with reference to the flowchart shown in FIG.

First, when the power is turned on, the stacker switch 42 is ON (step S1), and the shutter switch is OFF.
If so (step S2), the stack motor 21 is driven (step S3), and when the eccentric cam 22 rotates twice, it enters a standby state (steps S4, S5). Further, if the eccentric cam cannot rotate twice in step S4, it is presumed that the accumulation box 24 is full, and necessary processing such as prohibiting the subsequent bill receptacles is performed. That is, here, when the power is turned on, it is detected whether or not the banknotes in the accumulation box 24 are full. Although the eccentric cam 22 for pushing and storing the banknotes into the stacking box 24 can be rotated once, here, the eccentric cam 22 is rotated twice to ensure that the banknotes are stored.

Furthermore, if the shutter switch is ON in step S2 when the power is turned on, there is a tendency for bills, etc. to remain in the bill path in the identification device, so in that case, the conveyance motor is reversed (step 525). , performs an operation to return the remaining banknotes etc. to the banknote insertion slot side. If the banknote is completely returned, turn off the reverse rotation of the conveyance motor (step 530) and return to before step S3. If the banknote is not returned, check the timer time of approximately 3 seconds (step S26.527) and record the time. If the time has passed, the reverse rotation of the transport motor is turned off (step 828).
). After the motor is reversed and turned OFF, if there is a jam of banknotes or the like, the jam is cleared and the loop goes through the loop, and if the jam of banknotes is eliminated, the process returns to step S3 (step 529).
.

Furthermore, the banknote B is inserted from the banknote insertion slot 2 from the standby state of step S5, and the shutter switch is not ON (
Step S6), if the entrance sensor 41 detects the insertion of a banknote or the like, the entrance switch 41 connected to the entrance sensor turns OFF.
N (step S7), and the conveyance motor is driven to introduce the inserted banknote into the passage with the conveyance belt (step S8).

Here, in step S6, the shutter switch is turned ON.
When this happens, it is determined that there has been fraud by the fraudster, and the routine 2 is entered and the process proceeds to step 521. In step 521, the stack motor 21 is turned on and the eccentric cam 22 rotates to lift the push plate 17 to the top dead center.

Then, when the front three shutter switches are turned on (if not ON, the pushing plate 17 pushes the banknotes stored in the accumulation box 24 onto the compression plate 25 which is urged to the left in FIG. , and maintains suppression at top dead center.

Also, if the shutter switch is turned ON in step S22 by the wrongdoer, wait for about 3 seconds (step 523), and then return the top dead center state of the push plate 17 to the standby position. Turn on stack motor 21 again
Then, the eccentric cam 22 is rotated to return the push plate 17 to the standby position at the bottom dead center (step 524). Then, the process returns to step S5 in the standby state of routine (2).

The fraudulent act here is, for example, the act of first pasting a tape to one end of a genuine banknote, and then removing the genuine banknote with the tape that was stacked in steps 87 to 517 of the regular routine. That is, in order to retract the shutter plate protruding into the banknote passage from the passage, a thin celluloid plate or the like is inserted and the shutter plate is pressed (the shutter switch is turned on), and the tape-attached genuine banknote is pressed. There are fraudulent acts that attempt to extract the Therefore, in step S6, after the standby state in step S5, the shutter switch is first turned on and off.
When the shutter switch is turned on upon detection of the shutter switch, the processing from step S21 onward as described above will be performed. As explained in step S21, the genuine banknotes with tape that are stacked due to such fraud are
Since the eccentric cam 22 rotates and the pushing plate 17 presses the bill to the top dead center, the tape-attached genuine banknote cannot be pulled back.

Next, in step S8, the explanation returns to the normal route while the conveyance motor is turned on. After the tip of the banknote reaches the magnetic head 6, the magnetic head 6 first identifies whether the banknote B has magnetism or not, and if it has magnetism, it is recognized as a genuine banknote and the banknote is further conveyed (step S9 ). Then, while the bill reaches the shutter switch and continues ONL, if the magnetic pattern of the bill is the magnetic pattern of a regular bill, it is determined to be a genuine bill (step 5IO), and the bill is pressed against the shutter plate 28. After the banknote passes through and the shutter switch is turned off, the banknote is conveyed to the stack position and stopped (step S12.813).

Here, if it is determined in step S10 that the banknote is not a regular banknote, in the same manner as in steps S25 to S30,
The conveyance motor is reversed to return the banknote to the banknote insertion slot (step S31 to step 536).

Next, after stopping the transport motor, the stack motor 21
is driven to rotate the eccentric cam 22 to perform a banknote stacking operation (step 514), and when the stacking operation is finished and the eccentric cam 22 has rotated (step S15.51).
6), outputs a genuine bill signal (step 517), and returns to the standby state. In this step S16, the eccentric cam 22 is
When it does not rotate, that is, the eccentric cam 22 detects that the banknotes are full, and performs processing such as prohibiting the acceptance of subsequent banknotes, for example.

By the way, in step S9, when the output from the magnetic head 6 is No, it means that something other than a genuine bill, such as a celluloid plate made of a non-magnetic material, has been inserted into the bill path by a fraudster in order to pull out the bill. If the shutter switch is turned on and the predetermined magnetism is not detected, that is, if the shutter switch is turned on with an insert other than a genuine bill (step 519), the conveyance motor is stopped (step 520), and then The stack motor 21 is driven to rotate the eccentric cam 22 and push up the push plate 17, so that the push plate 17 is pressed to the top dead center toward the accumulation box 24 (step 521).

Here, unless the shutter switch is turned off in step S19, this state is maintained. When the shutter switch is turned off, for example, when a non-magnetic celluloid board is punched out by a fraudster (step 522), the shutter switch is turned off and turned off.
When it becomes FF, wait about 3 seconds (step 823)
, the push plate 17 is returned to the normal standby position by rotating the eccentric cam (step 524).

Furthermore, when the stacking box 24 is full of banknotes,
It is also conceivable that a fraudster inserts a thin plate of celluloid or the like into the banknote passage through the insertion slot.

In other words, by pasting tape, etc. on genuine banknotes and inserting them, the banknote accumulation box becomes full, and then by fraudulently inserting celluloid, etc., a shutter plate, etc. that protrudes into the banknote path is immersed, and the path is opened. However, it is also conceivable that the user tries to pull out the genuine banknote. When the shutter switch is turned on in this state, step S2
1, and then drive the stack motor to drive the eccentric cam 22.
is rotated to push the push plate 17 into the collection box 24 and hold it there. Further, in step S37, when the shutter switch is OFF, the stacker switch 42
is ON or OFF (step 538). Here, remove the collection box 24 and take out the banknotes inside.
After setting this collection box again, it will go into a standby state.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, when a celluloid board is inserted into a banknote passage for the purpose of banknote withdrawal, the banknote stacker motor is driven to maintain the eccentric cam at the top dead center position. This prevents bills from being pulled out. In addition, a genuine bill signal is output after the bill passes the withdrawal prevention lever, so
Even if you try to withdraw the banknotes afterwards, the withdrawal prevention lever can prevent the banknotes from being withdrawn.
