[Prior art]
In general, inside a device such as a vending machine, a change machine, a service device, etc., a bill processing device is installed that discriminates whether a bill that has been inserted is authentic or not, and that sequentially stores and stores only bills regarded as genuine bills. .
[0003]
FIG. 6 is a fragmentary sectional view of the banknote handling apparatus 1 described above.
[0004]
In the banknote handling apparatus 1, a shutter device 4 that opens and closes the banknote transport path 3 is disposed in the middle of the banknote transport path 3 communicating with the banknote insertion slot 2.
[0005]
This conventional shutter device 4 is supported so as to be rotatable about a shaft 5, and an L-shaped lever 6 whose front end portion 6 a can be moved into and out of the banknote transport path 3, and a rear end 6 b of the L-shaped lever 6. The plunger 8 of the solenoid 7 is pivotally supported by a shaft 9 whose tip 8a is supported by the rear end 6b of the lever 6.
[0006]
According to such a shutter device 4, as shown in FIG. 6, the L-shaped lever 6 is always rotated clockwise around the shaft 5 by the biasing force of an unillustrated initial position return spring of the plunger 8, As a result, the tip 6a is projected into the bill conveyance path 3 to block the passage 3.
[0007]
When a drive signal is sent to the solenoid 7 from a control device (not shown), as shown in FIG. 7, the plunger 8 of the solenoid 7 is sucked in the left direction of the drawing, so that the L-shaped lever 6 is connected to the shaft 5. Is rotated counterclockwise, the tip 6a of the lever 6 is allowed to escape from the inside of the banknote transport path 3, and the banknote transport path 3 is expanded.
[0008]
On the other hand, in this banknote processing apparatus 1, when a banknote A is inserted into the banknote insertion slot 2 as shown by an arrow B as shown in FIG. 6, a banknote detection sensor (not shown) disposed immediately after the banknote insertion slot 2 Insertion of A is detected.
[0009]
When the insertion of the bill A is detected, a drive signal is sent to the solenoid 7 based on the detection signal. As a result, the L-shaped lever 6 of the shutter device 4 disposed downstream of the bill insertion slot 2. 7 rotates counterclockwise about the shaft 5 as shown in FIG. 7 by suction of the plunger 8, thereby expanding the banknote transport path 3 and allowing the inserted banknote A to enter the banknote transport path 3. To do.
[0010]
When the insertion of the bill A is detected, the bill A is inserted into the bill transport path 3 as indicated by an arrow B by a bill transport means including a roller, a transport belt (not shown) disposed along the bill transport path 3. Is transported horizontally.
[0011]
When a bill detection 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. The lever 6 rotates clockwise about the shaft 5 by the biasing force of an unillustrated initial position return spring of the plunger 8, projects again into the banknote transport path 3, and closes the path 3.
[0012]
When the bill A is horizontally transported into the bill transport path 3 by a bill transport means (not shown), the correctness of the inserted bill A is detected by a bill authenticity detection sensor comprising a magnetic sensor (not shown) interposed in the middle of the bill. If the bill A is determined to be a fake bill by the bill true / false detection sensor, the shutter device 4 is actuated based on the detection signal, and the bill conveyance path 3 is expanded again to detect the fake bill. The banknote A determined as a ticket is returned from the banknote insertion slot 2.
[0013]
On the other hand, when the inserted bill 3 is determined to be a genuine note by a bill true / false detection sensor (not shown) described above, and after the purchase of the product or the like is finished, a stack signal of the bill A is sent, and based on the stack signal, The bills A are guided downward along the bill transport path 3 and are sequentially stacked and accommodated in a stacker 10 formed below the bill processing apparatus 1 by a stack mechanism (not shown).
[0014]
[Problems to be solved by the invention]
By the way, according to the conventional shutter device 4 applied to the paper sheet processing device such as the banknote processing device 1 described above, the tip 8a of the plunger 8 is connected to the rear end 6b of the L-shaped lever 6 and the shaft 9 as shown in FIG. The plunger 8 is supported so as to be rotatable about the shaft 8. When the L-shaped lever 6 is rotated counterclockwise about the shaft 5, the rotational force is transmitted in the moving direction of the plunger 8. This is a configuration.
[0015]
For this reason, for example, when the banknote transport path 3 shown in FIG. 6 is closed, a tool or a foreign object (not shown) is inserted into the banknote transport path 3 from the banknote insertion slot 2, and the tip 6 a of the L-shaped lever 6 is inserted into the plunger 8. It is possible to forcibly rotate counterclockwise about the shaft 5 against the biasing force of the initial position return spring, and when the L-shaped lever 6 rotates counterclockwise about the shaft 5 in this way, The banknote transport path 3 once closed is forcibly expanded by a tool. Therefore, the genuine banknote once transported into the banknote transport path 3 via a tape or the like attached to the rear end of the inserted banknote. There is a difficulty in preventing the mischief of forcibly pulling out the bill from the bill insertion slot 2.
[0016]
When the genuine bill is forcibly pulled out from the bill insertion slot 2 in this way, the bill processing apparatus 1 assumes that the genuine bill has been transported to the inside, and sells products and pays change. The process is normally performed.
[0017]
In view of the circumstances described above, an object of the present invention is to provide a shutter device for a paper sheet conveyance path that prevents as much as possible pulling out of a paper sheet from a paper sheet insertion port. To do.
[0018]
[Means for Solving the Problems]
In order to solve the above-described problems, according to the present invention, in the shutter device that opens and closes the paper sheet conveyance path, a lever that is rotatably supported around an axis and whose tip can freely move in and out of the paper sheet conveyance path, a solenoid having a plunger that reciprocates based on the electrical signal, a pin attached to integrally reciprocate and reciprocation of the plunger to the plunger tip, the rear end is formed the pins are fitted interpolated inverse of said lever A cam groove formed in the shape of a letter, and at the initial position of the plunger, the rotational force applied to the tip of the lever is transmitted in a direction perpendicular to the direction of movement of the plunger at the rear end of the lever. with restricting the rotation, during the movement of the plunger to push down the cam groove via the pin, the tip of the lever the lever about the axis before And comprising a coupling means for rotating the direction to escape from the sheet conveying path.

【Example】
An embodiment of the shutter device according to the present invention will be described in detail below.
[0021]
FIG. 1 is a fragmentary sectional view of a bill processing apparatus 1 to which a shutter device 20 according to the present invention is applied, and the same parts as those in FIG.
[0022]
A shutter device 20 that opens and closes the banknote transport path 3 is disposed in the banknote transport path 3 of the banknote handling apparatus 1.
[0023]
The shutter device 20 is a lever 23 that is rotatably supported around a shaft 21 as shown in FIG. 2 shown in the top view and FIG. 3 shown in the side view, and has a claw formed at the tip. A lever 23 arranged so that 22 can freely move in and out of the bill transport path 3, a solenoid 25 having a plunger 24 connected to the rear end of the lever 23, a plunger 24 of the solenoid 25, and a rear of the lever 23 It is comprised from the connection means 30 which connects an end.
[0024]
As shown in FIG. 2, the lever 23 includes a pair of arms 26 and 27 disposed at a predetermined interval, and an elevating rod 28 fixed so as to connect the tips of the arms 26 and 27. Thus, seven claws 22 are integrally formed on the lower surface of the lifting rod 28 along the longitudinal direction of the lifting rod 28, in other words, along the width direction of the banknote transport path 3 shown in FIG. ing.
[0025]
On the other hand, the connecting means 30 for connecting the plunger 24 of the solenoid 25 and the rear end of the lever 23 comprises a pair of cylindrical pins 31 supported on the tip of the plunger 24 as shown in FIG. As shown in FIG. 2, the pins 31 protrude from both sides of the base member 32 engaged with the tip of the plunger 24. Further, as shown in FIG. 3, the base member 32 is placed on a base 41 disposed on one chute 40 forming the banknote transport path 3, and is slidable in the horizontal direction on the base 41. It is supported to become.
[0026]
On the other hand, as shown in FIG. 2, the rear ends 26 a and 27 a of the pair of arms 26 and 27, which are the rear ends of the lever 23, have a rounded shape as shown in FIG. An inverted cam groove 33 is formed, and the pin 31 is inserted into the cam groove 33.
[0027]
According to such a shutter device 20, when the plunger 24 is returned to the initial position by the biasing force of the initial position return spring 42 as shown in FIG. 1, the lever 23 is counterclockwise about the shaft 21 via the connecting means 30. Then, the claw 22 is protruded into the banknote transport path 3 to close the banknote transport path 3.
[0028]
When a drive signal is sent from a control device (not shown) to the solenoid 25, the plunger 24 of the solenoid 25 is sucked in the right direction of the drawing as shown in FIG. The lever 23 rotates around the shaft 21 in the clockwise direction by a predetermined angle, thereby causing the claw 22 to escape from the banknote transport path 3 to expand the banknote transport path 3.
[0029]
By the way, according to the shutter device 20 described above, as shown in FIG. 4, the cam groove 33 into which the pin 31 of the connecting means 30 is inserted is formed in a reverse shape, so that as shown in FIG. In the initial position of 24, that is, in a state in which the bill conveyance path 3 is closed by the claw 22, a force is applied to the claw 22 as shown by an arrow C with a tool (not shown) to forcibly expand the bill conveyance path 3. When the lever 23 is rotated clockwise about the shaft 21, the rear end of the lever 23, that is, the rear end 27a (26a) of the arm 27 (26), as shown in FIG. A force in a direction perpendicular to the moving direction (arrow E) of the plunger 24 as indicated by the arrow D is applied to the pin 31 . However, since the movement of the pin 31 in the direction of arrow D is restricted by the base member 32 and the base 41, the rotation of the lever 23 is locked by the pin 31 and the rotation is prevented.
[0030]
Since the force acting on the pin 31 indicated by the arrow D acts in a direction perpendicular to the moving direction of the plunger 24, naturally, the force is not transmitted in the moving direction of the plunger 24, and accordingly, the pin 31 indicated by the arrow D is used. The plunger 24 does not move due to the force acting on.
[0031]
【The invention's effect】
As described above, in the shutter device of the present invention, the force of the lever at the initial position of the plunger is transmitted in the moving direction of the plunger by the connecting means for connecting the plunger front end and the lever rear end, Since the rotation of the lever is restricted, even if an attempt is made to forcibly rotate the tip of the lever when the paper sheet transport path is blocked, the lever does not rotate as much as possible to block the paper sheet transport path. Therefore, the mischief of forcibly pulling out the paper sheet once transported into the paper sheet transport path can be prevented as much as possible.
