2. Description of the Related Art Generally, inside a device such as a vending machine, a money changer, a service device, etc., a bill processing device for discriminating the authenticity of inserted bills and sequentially accumulating and storing only the bills regarded as genuine bills. Is installed.

FIG. 6 is a fragmentary cross-sectional view of the bill processing apparatus 1 described above.

In the banknote handling apparatus 1, a shutter device 4 for opening and closing the banknote transport path 3 is disposed in the banknote transport path 3 communicating with the banknote insertion slot 2.

The conventional shutter device 4 is rotatably supported about a shaft 5 and has an L-shaped lever 6 whose tip 6a can be retracted into and out of the banknote transport path 3, and the L-shaped lever 6. The solenoid 7 is engaged with the rear end 6b, and the plunger 8 of the solenoid 7 has its front end 8a pivotally supported by a shaft 9 supported by the rear end 6b of the lever 6.

According to such a shutter device 4, as shown in FIG. 6, the L-shaped lever 6 is normally rotated clockwise about the shaft 5 by the urging force of an unillustrated initial position return spring of the plunger 8. As a result, the tip 6a is projected into the bill transport path 3 to close the path 3.

Incidentally, the solenoid 7 is supplied from a control device (not shown).
7, the plunger 8 of the solenoid 7 is attracted to the left side of the drawing, whereby the L-shaped lever 6 rotates counterclockwise about the shaft 5 as shown in FIG. The tip 6a of the lever 6 is made to escape from the inside of the banknote transport path 3 to expand the banknote transport path 3.

On the other hand, in the banknote processing apparatus 1, when the banknote A is inserted into the banknote insertion slot 2 as shown by the arrow B as shown in FIG. 6, the banknote detection (not shown) arranged immediately after the banknote insertion slot 2 is detected. The insertion of the bill A is detected by the sensor.

When the insertion of the banknote A is detected, a drive signal is sent to the solenoid 7 based on the detection signal, and as a result, the L-shaped shutter device 4 arranged downstream of the banknote insertion slot 2. The lever 6 rotates in the counterclockwise direction around the shaft 5 as shown in FIG. 7 due to the suction of the plunger 8, thereby expanding the banknote transport path 3 and inserting the inserted banknote A into the banknote transport path 3. Allow entry.

When the insertion of the banknote A is detected, the inserted banknote A is inserted into the banknote A as indicated by an arrow B by the banknote conveying means including rollers (not shown) and a conveyor belt arranged along the banknote conveying path 3. It is horizontally transported along the transport path 3.

When a bill detecting sensor (not shown) detects that the rear end of the inserted bill A has passed through the shutter device 4, the drive signal to the solenoid 7 is stopped, and as shown in FIG. , L-shaped lever 6 is driven by the urging force of a spring (not shown) for returning the initial position of plunger 8 to shaft 5.
Is rotated in the clockwise direction around the center, and it again projects into the banknote transport path 3 and closes the path 3.

The banknote A is fed by a banknote conveying means (not shown).
When the paper money is horizontally conveyed into the paper money conveyance path 3, the authenticity of the inserted paper money A is determined by a paper money authenticity detection sensor including a magnetic sensor (not shown) interposed in the middle, and the paper money authenticity detection is performed. When the banknote A is determined to be a counterfeit banknote by the sensor, the shutter device 4 is operated based on the detection signal, the banknote transport path 3 is opened again, and the banknote A determined to be the counterfeit banknote is inserted into the banknote insertion slot. Return from 2.

On the other hand, when the inserted bill 3 is determined to be a genuine bill by the above-described bill authenticity detection sensor (not shown), and when the purchase of the product or the like is finished, the stack signal of the bill A is sent and the stack signal is sent. Based on this, the banknotes A are guided downward along the banknote transport path 3 and sequentially stacked and housed in the stacker 10 formed below the banknote processing apparatus 1 by a stacking mechanism (not shown).

[0014]

By the way, according to the conventional shutter device 4 applied to the paper sheet processing apparatus such as the banknote processing apparatus 1 described above, as shown in FIG.
Has a structure in which a tip end 8a of the L-shaped lever 6 is rotatably supported by a rear end 6b of the L-shaped lever 6 about a shaft 9, and the plunger 8 is counterclockwise about the L-shaped lever 6 about the shaft 5. When rotated, the rotational force is transmitted in the moving direction of the plunger 8.

Therefore, for example, the banknote transport path 3 shown in FIG.
At the time of closing, the unillustrated tool, a foreign object, or the like is inserted into the bill transport path 3 from the bill insertion slot 2, and the tip 6a of the L-shaped lever 6 is inserted.
Can be forcibly rotated counterclockwise about the shaft 5 against the biasing force of the spring for returning the initial position of the plunger 8, and thus the L-shaped lever 6 rotates counterclockwise about the shaft 5. When rotated in the direction, the banknote transport path 3 that has been once closed is forcibly expanded by a tool, and thus is once transported into the banknote transport path 3 via a tape or the like attached to the rear end of the inserted banknote. There was a difficulty in preventing the mischief of forcibly pulling out genuine bills from the bill insertion slot 2.

When the genuine bills are forcibly pulled out from the bill insertion slot 2 in this way, the bill processing apparatus 1 considers that the genuine bills have been conveyed inside, and sells and changes the merchandise. Process payment etc. normally.

In view of the above-mentioned circumstances, the present invention provides a shutter device for a paper sheet conveying path, which is forcibly prevented from forcibly pulling out a paper sheet from a paper sheet insertion port. With the goal.

[0018]

In order to solve the above-mentioned problems, according to the present invention, in a shutter device for opening and closing a paper sheet conveying path, the shutter device is rotatably supported around an axis, and the leading end is the paper sheet. A lever having a retractable and retractable lever in the transport path, a solenoid having a plunger that reciprocates based on an electric signal, a cam disposed at the tip of the plunger, and a cam into which the cam formed at the rear end of the lever is fitted. In the initial position of the plunger, the rotational force applied to the tip of the lever is transmitted in the direction perpendicular to the moving direction of the plunger at the rear end of the lever to restrict the rotation of the lever, When moving, the cam groove is pushed down via the cam and the lever is rotated around the shaft in the direction in which the tip of the lever escapes from the inside of the paper sheet conveyance path. And it includes a connecting means that.

[0019]

According to the above-mentioned shutter device, the connecting means for connecting the plunger front end and the lever rear end does not transmit the compulsory rotational force of the lever at the initial position of the plunger in the moving direction of the plunger. Since the rotation is regulated, even if the tip of the lever is forcibly rotated when the paper sheet conveyance path is blocked, the lever does not rotate, and therefore the paper sheet conveyance path can be blocked as much as possible. Will be maintained.
