BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill validator, and more particularly to a bill validator suitable for simple use on a desk.

[0002]

2. Description of the Related Art Conventionally, a desk-top type bill validator that can be easily used has been used for discriminating the authenticity of bills (for example, US dollar bills) on a desk or the like.

[0003] As a conventional bill validator of this type, there is, for example, one disclosed in Japanese Utility Model Publication No. 1-421010. When the bill described in this publication is also placed on a table and a bill is inserted from the bill insertion slot on the front side, identification is performed while the bill is conveyed inside. The bill is discharged to the bill insertion slot on the front side when the bill is a rejected bill.

[0004]

However, according to the above-mentioned conventional technique, when the inserted bill is a reject bill, the reject bill is returned to the bill insertion slot. There has been a problem that the leading end of a certain reject bill collides near the bill insertion slot, causing the reject bill to jam in the transport system or damaging the edges of the inserted bill and the reject bill.

When a rejected bill is returned, the bill set in the bill insertion slot is once removed, the rejected bill to be returned is removed, and then the next bill must be set again in the bill insertion slot. Must
There has been a problem that the operation is extremely troublesome and the operation efficiency is poor.

In view of the above, the present invention provides a bill validator capable of eliminating the trouble of removing a rigid bill every time, preventing the occurrence of jamming in a transport system, and performing a bill distinguishing operation with high efficiency. The purpose is to:

[0007]

As means for solving the problems of the above-mentioned prior art, the present invention provides an airframe, a bill insertion slot provided on the front side of the airframe and for inserting bills one by one, A bill outlet that opens toward the front of the body at the rear of the body, and a bill discriminating transport path that can be driven in reverse and has a discriminator in the middle of transporting the bill inserted from the bill insertion port toward the bill outlet. A stack unit provided above the bill discriminating transport path for accumulating bills sent from the bill sending port, and a reject bill storing unit provided at a lower position of the bill discriminating transport path for storing reject bills. An advance position provided at a predetermined position of the bill discriminating conveyance path to guide the conveyed bill to the reject bill storage section while intersecting with the bill discriminating conveyance path, and a retracting position for retracting the conveyed bill from the conveying path and moving the conveyed bill straight. Between the switching member and the switching member in the advance position or the retreat position to the retreat position or the advance position. And a friction clutch for interlocking rotation with forward / reverse drive of the road.

[0008]

When a bill is inserted from the bill insertion slot, the bill is transported backward by forward rotation of the bill discriminating and conveying path in the machine, and the authenticity of the discrimination section in the conveying path is identified. When the discrimination result is determined to be a genuine bill, the conveyance is continued as it is, discharged from the bill outlet to the stack unit, and accumulated in the stack unit.

When it is determined that the bill is a rejected bill, the bill discriminating conveyance path is driven in reverse to return the bill to be rejected, and at the same time, the switching member advances to a position intersecting the conveyance path.
The reject bill is sent to the reject bill storage unit. During the reverse feeding of the rejected banknote, the transport path is driven to rotate in the reverse direction, so that even if the next banknote is inserted, it will not be taken in, and no jamming will occur inside.

In the above embodiment, the bill discriminating and conveying path 2 has a roller structure, but may have a belt structure.

Next, the operation of the above embodiment will be described.

When a bill is inserted from the bill insertion slot 4, the bill is conveyed rearward by the forward rotation of the bill discriminating and conveying path 2 in the machine body 3, and the color sensor S ₁ and the magnetic sensor provided in the conveying path 2 are provided. authenticity is identified by _{S 2, S 2, S 2} . At this time, the switching members 30 and 30 are rotated by the forward rotation of the pulley 37 so that the shaft 29 is rotated via the friction clutch 35 and locked at a position retracted from the conveyance path 2 by a stopper (not shown). Slip due to slippage.

When the above-mentioned identification result is determined to be a genuine bill, the bill is conveyed as it is and discharged from the bill outlet 10, and
It is integrated on the stack unit 11. If it is determined that the bill to be rejected by the sensors of the identification unit, the motor 40 is driven to rotate in reverse when the rear end of the rejected bill has passed through the fluorescent sensor S ₃ by the identification signal, in contact with the belt 46 When the pulley 37 rotating in the reverse direction rotates the shaft 29 via the friction clutch 35, the switching device 2
8, the switching members 30, 30 advance to a position (the state shown in FIG. 2) intersecting with the transport path 2 and are stopped by being stopped by a stopper (not shown). Thereafter, the pulley 37 idles due to slippage of the friction clutch 35.

Therefore, the rejected bill to be sent out is
It enters between the switching members 30 and 30 and the belt 33 that rotates in the reverse direction via the one-way clutch 34, and is held between the belt 33 and the roller 31 </ b> A that rotates following the belt 33 and is rejected. Sent inside. One end of the reject bill fed into the reject bill storage unit 5 projects from the reject bill outlet 5a on the front surface of the machine body 3 and is stored in a state where it can be taken out.

The rejected bills are stored in the rejected bill storage 5
(After actually rejected bill backhaul has been trailing end of the bill has passed the sensor S _3, a predetermined time elapse) Storage time points to a reversible motor 40 in order to accept the next bill is normal rotation, Rollers 13, 14, 15, belts 24, 2
7. The roller 26A is rotated forward. Here, assuming that the one-way clutch 34 is not interposed between the shaft 17 and the roller 32 and the shaft 17 and the roller 32 are fixed, the roller 32, the belt 33, and the roller 32A is also rotated forward, and the rear end of the rejected bill is the belt 3
3. When the rejected banknote is located near the roller 31A, the rear end of the rejected banknote is held again by the belt 33 and the roller 31A and is sent out again from the rejected banknote storage unit 5 to the banknote discriminating and conveying path 2 and overlaps with the next inserted banknote. Inconveniently occurs in the normal rotation direction. Therefore, a one-way clutch 34 is interposed between the shaft 17 and the roller 32 so that the roller 14 and the belt 33 are not rotated during the normal rotation of the reversible motor 40. The roller 31A is also rotated in the reverse direction because the belt 33 is pressed.
The stop is maintained through the stop of the bill, and functions as a guide for the lower surface of the inserted and forwarded bill.

During the reverse feeding of the rejected banknote, the transport path 2 is driven in reverse, so that even if the next banknote is inserted into the banknote insertion slot 4, it is not taken in, and jamming may occur inside the machine body 3. Absent.

[0029]

As described above, according to the present invention, the rejected bills are returned to the rejected bill storage unit without being returned to the bill insertion slot. No collision occurs, jamming can be completely eliminated, and the conventional problem that the next banknote cannot be inserted until the rejected banknote is returned and pulled out is solved, so that the efficiency of business can be improved.
