Generally, a vending machine or a currency exchange machine includes a bill identification device that identifies whether inserted bills are genuine or fake, and a bill stacking device that stores only genuine bills inserted into the tray.

The banknotes are sent from the banknote insertion slot to the banknote collection box 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 identification device from being pulled out to the banknote entrance side by fraudulent means, a shutter plate is provided in the banknote passageway to block the banknote passageway.

[Problem to be solved by the invention]

However, in the conventional device described above, there is a problem in that a long plastic thin plate or the like is inserted into the bill passage through the bill insertion slot and the shutter plate is artificially retracted to withdraw the bill.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bill withdrawal prevention device that prevents bills from being pulled out by inserting a thin plastic plate from a bill insertion slot along a bill path.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a banknote processing device that distinguishes between genuine and fake banknotes inserted from a banknote insertion slot and stacks only genuine banknotes in a banknote accumulation box through a banknote path. This pull-out prevention device has a pull-out prevention lever with a hook groove formed on the inside with the toe facing away from the insertion port, and this pull-out prevention lever rotates around the pivot shaft. It is characterized by being spring-loaded so as to block the banknote passage.

[For production]

According to the present invention, even if a thin plastic plate is inserted into the banknote passage through the banknote insertion slot and an attempt is made to pull out the banknote,
The end of the banknote that is about to be pulled out is caught in the hook groove of the claw member of the withdrawal prevention lever, thereby preventing the banknote from being pulled out to the outside.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a banknote withdrawal prevention device according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a side cross section of an embodiment of a banknote processing apparatus to which the present invention is applied.A housing 1 of this banknote processing apparatus is provided with a banknote insertion slot 2 on the front surface, and a cover 3. The banknotes can be inserted into the insertion slot 2 by lifting the banknotes upward. Inside the housing 1, there are formed a horizontal bill passage 4 and a vertical bill passage 5 that are continuous in a substantially L-shape so as to communicate with the insertion opening 2. Above the banknote passage 4, a magnetic head 6 is provided as a means for identifying authenticity of banknotes, and a head pressing roller 7 is placed on the opposite side of the magnetic head 6.

Pulleys 8.9 are arranged before and after this head pressing roller rough, and a belt 10 is stretched in parallel between these pulleys. Further, the pinch roller 11 presses the pulley 8 from above the belt 10.

On the other hand, a pair of driving pulleys 12.12 are arranged at a distance from each other on one side of the vertical banknote passage 5, and driven pulleys 14.14 corresponding to these driving pulleys are connected to the housing 1.
It is located at the bottom of the .

A storage belt 15 is stretched in parallel between each drive pulley 12 and the pair of driven pulleys 14. A banknote pushing device 16 is provided inside these storage belts 15. A push plate 17, a pair of link rods 19 and 20 whose one end is pivoted to the back surface of the push plate 17, and whose other end is attached to the fixed shaft 18 through an elongated hole, and a motor around the rotation center O. It is composed of an eccentric cam 21 that is driven. The push plate 17 also has a coil spring 2.
2.22 is spring biased towards the pushing device 16. Further, on the other side of the bill path 5, a stacking box 23 for stacking the bills B pressed by the pushing device 16 is provided. A compression plate 24 is arranged within this collection box 23 and is biased to the left in the figure by a spring rod 25.

By the way, a shutter plate 26 is provided in the connection area of the banknote passage 4.5, and one end of this shutter plate 26 is used within the banknote passage 5. The shutter plate 26 is pushed by the banknotes B moving in the banknote receiving direction and automatically retreats out of the passage, but functions as a stopper for banknotes moving in the opposite direction.

Thus, according to the invention, the bottom plate 2 of the accumulation box 23
A banknote withdrawal prevention bag wit28 is provided below the inner end of the banknote 7. As shown in FIG. 2, this pull-out prevention device 28 includes a bracket plate 29, a pull-out prevention lever 3o, and a pivot shaft 31 that connects the two. The bracket plate 29 is attached with ear pieces 29a, 2
921, and a U-shaped bracket main body 29b which is open at the top and connects these together.

On the other hand, the withdrawal prevention lever 3o has a pair of claw members 32 whose toes 32a extend obliquely upward away from the bill insertion slot 2, and a hook groove 33 is formed above the claw members 32. These claw members 32 are integrally connected by a connecting plate 34, and a tongue piece 35 is erected approximately at the center thereof. This tongue piece 35 effectively prevents the lower end of the banknotes stored in the accumulation box 23 from hanging down into the banknote passage 5.

As is clear from FIG. 3, a stop surface 32b is formed at the rear of the lower surface of the claw member 32. As shown in FIG.

Further, the pull-out prevention lever 30 is rotatably supported around a pivot shaft 31, and a coil spring 36 is mounted on the pivot shaft 31, and one end 36a of the coil spring 36 is attached to a side surface of the connecting plate 34. The other end 36b is locked by the side surface of the bracket body 29b of the bracket plate 29. Therefore, the pull-out prevention lever 30 is moved by the spring force of the coil spring 36.
In FIG. 1, the spring is biased around the pivot shaft 310 in a counterclockwise direction, that is, in a direction in which the pawl member 32 blocks the banknote passage 5.

Next, an explanation will be given with reference to FIGS. 4 to 7 of how to prevent fraud in the case where a banknote with tape T pasted to the rear end of the genuine banknote B is once placed in the receiver and then pulled out due to a fraudulent act.

In FIG. 4, a genuine banknote B with a tape T connected thereto is inserted into the banknote passage 4 through the insertion slot 2 in the same manner as usual, and the banknote B is identified by the magnetic head 6 as genuine or fake.

Then, after the genuine banknote B moves inside the banknote path 5 by retracting the shutter plate 26 to the outside of the path, the withdrawal prevention lever 30 is moved back against the spring force of the coil spring 36 and the genuine banknote B is introduced into the banknote path 5. be done.

When the banknote B reaches the stack position corresponding to the push plate 17, the banknote stops, and the eccentric cam 21 rotates twice to cause the push plate 17 to reciprocate twice. The pushing plate 17 pushes the banknotes B into the accumulation box 23 against the compression plate 24. Note that in order to store banknotes that have stopped at the stack position in the stacking box, the eccentric cam 21 may be rotated once and the push plate 17 may be reciprocated once. It would be better to rotate the push plate 17 twice and make the push plate 17 reciprocate twice.

Here, as shown in FIG. 6, even if the fraudster inserts the celluloid plate 38 into the banknote passage 4 through the insertion slot 2, moves the shutter plate 26 out of the passage, and attempts to pull out the banknote B. , the end of the banknote B is caught in the hook $33+ of the withdrawal prevention lever 30, and the withdrawal of the banknote B is prevented.

Incidentally, if the fraudster inserts the celluloid board 38 deeper and presses the claw member 32 of the withdrawal prevention device 28 to try to pull out the banknote B, the tongue piece 35 will push the frontmost banknote B to the back. Because it acts like a push, the banknote B
is prevented from being pulled out. As a result, the tongue piece 35 not only prevents the bill from hanging, but also works effectively against fraudulent attempts to pull out the bill.

(Effects of the Invention) As is clear from the above description, according to the present invention, the banknote withdrawal prevention lever is provided in the banknote passage and is energized to block the banknote path by a spring force under normal conditions. Even if a thin plastic plate is inserted in an attempt to pull out the genuine banknotes with taped tape once stored in the collection box, the edges of the banknotes will be caught in the hook groove of the withdrawal prevention lever. It is possible to reliably prevent banknotes from being pulled out.
