[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bill handling device, particularly a bill discriminating device, a stacker for storing bills determined to be genuine by the bill discriminating device, and bills between the bill discriminating device and the stacker. The present invention relates to a bill handling device that includes a carrying device for carrying and that can prevent unauthorized removal of inserted bills.

[0002]

2. Description of the Related Art Generally, bill handling apparatuses such as currency exchange machines and vending machines determine the authenticity of inserted bills with a central control unit (CPU) comprising a microcomputer based on detection data. (Validator). The banknote that has been determined as a true bill by the banknote discriminator passes through the banknote discriminator, is transported by the transport device, and is stored in the stacker.

A pull-out prevention device provided in a bill validator and for preventing unauthorized removal of a inserted bill has, for example, a movable lever rotatably provided in a transport path and detecting passage of the bill. The movable lever is rotated when the leading end of the bill passing through the bill validator contacts, and the rotation of the movable lever is detected by an optical sensor such as a photocoupler. The central controller monitors the signal transmitted from the optical sensor, and determines whether the detection signal obtained corresponding to the length from the beginning to the end of the bill has a predetermined pattern.

[0004] The central controller determines that the bill is a genuine bill if the detection signal for a predetermined time obtained from the bill is within the set value. When illegally pulling out a bill stored in the stacker, a sheet material having substantially the same width dimension as the bill is fixed to the end of the bill. When the sheet material is fixed to the bill, the optical sensor detects the presence of the sheet material even after the bill passes through the movable lever. Further, the movable lever is still held in the operating posture because of the sheet material existing in the paper money transport passage. Even after the bill is stored in the stacker, the optical sensor
The signal is continuously transmitted over a preset detection time. For this reason, the central control device receives the output of the optical sensor, determines that the sheet material is connected to the bill stored in the stacker, and then stops the operation of the transport device and the like. If necessary, a warning such as an abnormal alarm may be generated by a built-in warning device.

In another pull-out prevention device in which a claw-shaped movable lever is urged by a spring and installed so as to be able to protrude into the conveyance path,
A bill conveyed toward the inside of the bill discriminating device contacts the rotating lever. The rotating lever is rotated by the transported bill to a position outside the transport path, and the bill passes over the rotating lever. When the bill completely passes through the pivot lever,
The rotating lever projects into the transport passage by a spring. For this reason, even if the pulling member such as a string or a wire fixed to the end of the bill is pulled to attempt to pull the bill back, the bill is hooked on the rotating lever protruding into the transport path, and illegal removal is prevented. You.

[0006]

However, in the conventional bill handling apparatus, since the movable lever or the rotation lever of the pull-out preventing device is provided in the bill validator, it is possible that the bill is illegally pulled out. For example, after the bill passes through the movable lever, a tool is inserted into the bill validator to move the movable lever out of the conveyance path, and a pulling means such as a string, a wire or a sheet material fixed to the end of the bill is used. Pulling and extracting bills may occur. Then, this invention aims at providing the banknote handling apparatus which can prevent illegal removal of a banknote reliably.

At this time, as shown in FIG. 4, the pull-out preventing device 21 in the transport device 20 is rotated by the rotation lever 2 rotatably supported by the support shaft 21b.
1a is pulled by the elastic force of the spring 21e via the pin 21c and the plunger 21d, and is at a protruding position where it is engaged with the slit 22c formed in the transport guide 22.

When the bill 1 is inserted into the bill discriminating apparatus 10, the bill discriminating apparatus 10 determines the authenticity of the bill from the detection data such as the transmitted light amount of the bill 1. For example, the level of whether or not the amount of transmitted light is within the range of the set value is determined, and bills out of the level are returned to the entrance 11 without being determined as a true bill. When the banknote 1 is determined to be a true bill, the central control device sends the banknote 1 from the bill validator 10 to the transport device 20 and causes the motor 25 of the transport device 20 to rotate forward.

The bill 1 having passed through the bill discriminating apparatus 10 passes through the entrance 22a of the transport guide 22, and the bill passage detecting sensor 62 detects the passage of the bill 1. The detection signal of the bill currency detection sensor 62 is sent to the central controller, and the central controller sends a drive signal to the solenoid 21f. When the solenoid 21f is driven, the plunger 21d is pulled toward the solenoid 21f against the elasticity of the spring 21e, so that the rotating lever 21a is pivoted about the support shaft 21b in FIG.
Is rotated from the protruding position shown in FIG. 5 to the retracted position shown in FIG.
When the rotation lever 21 rotates to the retracted position, the rotation lever 2
1 is disengaged from the slit 22c of the transport guide 22, and the transport of the banknote 1 is not hindered. When the rotation lever 21a moves to the retracted position, the light of the detection sensor 60 is blocked, and a detection signal generated from the detection sensor 60 is sent to the central control device. The central controller receives the detection signal of the bill passage detection sensor 63, and stops the operation of the solenoid 21f when the bill passage detection sensor 63 detects the passage of the leading end of the bill 1. Therefore, the plunger 21d is pulled by the urging force of the spring 21e, and the rotating lever 21a contacts the surface of the bill 1. On the other hand, the central controller monitors the length of the bill 1 while comparing a predetermined signal detection time corresponding to the length from the leading end to the end of the bill 1 with the detection signal of the detection sensor 60. Thus, the bill 1 is transported by the transport belt 23.
Is fed toward the stacker 50 along the transport guide 22. During the forward rotation of the motor 25, the one-way clutch type transmission pulley 46 does not run idle.

When the end of the bill 1 passes through the rotating lever 21a, the rotating lever 21a is engaged with the slit 22c provided in the transport guide 22 and returns to the protruding position shown in FIG. The portion projects into the transport passage 27. The bill 1 is supplied to the cassette 51 through the supply port 59.
Is stored inside. If the banknote 1 is to be pulled out when the rotation lever 21a is at the protruding position, the starting end of the banknote 1 comes into contact with the tip of the rotation lever 21a, so that the banknote 1 can be prevented from being pulled out.

As described above, in this embodiment, when the bill 1 is attached to the bill 1 and the bill 1 stored in the stacker 50 is pulled, the bill 1 is pulled out by the rotation lever 21a.
Is blocked by In addition, since the bent portion 22d is formed, the rigid tool inserted into the bill validator 10 cannot reach the rotation lever 21a, and the rotation lever 21a cannot be seen from the entrance 11. Cannot rotate the rotation lever 21a to the retracted position illegally.
Can be reliably prevented from being illegally extracted.

Further, bill passage detecting sensors 62 and 63 for detecting passage of the bill 1 are provided near the entrance 22a and the exit 22b of the carrying guide 22 of the carrying device 20. Is detected by the detection sensor 60, the detection sensor 60 detects the operation of the solenoid 21f that operates the rotation lever 21a of the pull-out prevention device 21.
The length from the beginning to the end of the bill passing detection sensor 62,
By detecting at 63, it is possible to determine whether or not the length of the bill 1 is regular.

[0029]

As described above, according to the present invention, the rotation lever provided on the transfer device prevents the bill from being pulled out, and the bent portion prevents the tool from entering the rotation lever and prevents the bill from being visually checked. It is possible to reliably prevent the moving lever from being illegally rotated to the retracted position. Furthermore, since the plunger of the solenoid is arranged in parallel with the transfer passage of the transfer device, and the plunger is moved in parallel with the transfer passage by the solenoid and the spring to rotate the rotating lever, the plunger rotates in the transfer device in a small space. The lever can be operated smoothly.
