Rotate by 2). Further, a delivery roller (71) is fixed to the shaft (93) having a pulley (90) attached to the shaft (31) and a pulley (92) connected by a belt (91). 71) is a plate
The delivery roller (70), which is rotatably supported by the (94), contacts and rotates. A bill storage unit (7) for high-value bills is arranged behind the delivery rollers (70) (71).

The operation of the above configuration will be described. First, when inserting a bill into the insertion slot (1), the belt is rotated by the rotation of the pull-in rollers (11) (12).
This bill is taken into the transfer device (2) by the carrying operation (17). Then, the detection head (21) generates a detection force corresponding to the conveyed bills, and the above-mentioned discrimination circuit discriminates the properness and type of the bills. Then, when the identification circuit determines that the conveyed bill is not suitable, the deceleration motor (13) reversely drives the belt (17) in the opposite direction, and the bill is inserted into the insertion slot (1).
Is returned to the outside of the aircraft. On the other hand, if appropriate, the deceleration motor (26) is driven when the tip of the bill reaches the sensor (69A) consisting of a set of LED and phototransistor, and the bill is fed into the belt (33) and the guide stock (3). It is taken into a bill receiving path (5) formed between the one surfaces of the two. If the bill is a high-value bill, the belt (33) continues to be driven, so that the bill is conveyed in the receiving direction and then introduced into the bill storage unit (7) by the sending rollers (70) and (71). And the deceleration motor (26)
It stops after a lapse of a predetermined time after the trailing edge of the bill has passed through the sensor (72) consisting of a set of LEDs and a phototransistor.

If the bill is a low-value bill, this bill will be detected by the sensor (69).
Belt (33) is stopped when passing the
The bills taken into (5) are guided to the bill stack section (8), but there are two timings for stopping this conveyance. That is, the banknote stacking unit (8) holds the adjacent banknotes in a state of being alternately shifted in the longitudinal direction, but as shown in FIG. 6, the banknotes are stored by the claw member (49) and the locking member (59). , The deceleration motor (26) is stopped immediately after the rear end of the low-value banknote taken in by the belt (33) has finished passing through the sensor (69). As shown in the figure, when the upper end of the stored bill is held by the claw member (48) and the locking member (58), the rear end of the bill taken by the belt (33) passes through the sensor (69). The deceleration motor (26) is stopped after a short delay time. Now, assuming that the banknotes in the banknote stack section (8) are being held by the claw member (48) and the locking member (58) and the low-value banknotes have been taken in by the belt (33), the banknotes (7
3) has passed the sensor (69) and after a delay time, the motor
Since the bank (26) is stopped, the bill (73) is taken up to a position where the leading end of the banknote (73) approaches the lower wall (37) of the banknote stack section (8). Then, the deceleration motor (54) is driven to rotate the rotary shafts (52) and (53) counterclockwise by 90 °, and the claw members (48) and (49) are opened in the opening (4) as shown in FIG. Extend in the direction. At this time, the cams (62) (67) rotate clockwise by 90 ° in conjunction with the rotation of the rotary shafts (52) (53), so that the locking members (58) (59) move to the partition plate (3).
Exit behind 9). Therefore, the claw members (48) (49) and the locking members (58) (59) for the banknotes stored in the banknote stack section (8)
All the pressing of is released.

FIGS. 7 to 10 are sectional views showing the operation of pushing the low-value banknotes into the banknote stacking section (8). In the standby state shown in FIG. 7, the stack plate (42) has exited from the opening (4), and the banknotes (74) stored in the banknote stacking section (8) are belts.
It is held between the roller (33) and the roller (41). Then, by rotating the cam (47) by driving the deceleration motor (46), the stack plate (4
When the guide portion (44) of 2) comes into contact with the protrusion of the cam (47), as shown in FIGS. 8 and 9, the stack plate (42)
Moves through the opening (4) into the bill stack (8) and pushes the bill against the spring (38). Tete cam (47)
After one rotation, the cam (75) fixed on the same axis and the position detection switch (76) are confirmed to return to the standby position, and the deceleration motor (46) is stopped. In this way the transfer device
When the take-in of the low-value banknotes introduced from (2) by the belt (33) is completed, the deceleration motor (46) is rotated once to introduce the banknotes into the banknote stack section (8).

When the deceleration motor (54) is driven to further rotate the rotary shafts (52) and (53) counterclockwise by 90 °, the claw member (49) extends inward of the banknote stack section (8). At the same time, the locking member (59) is projected toward the partition plate (39) by the rotation of the cam (67) which is interlocked with the rotating shaft (53). Therefore, as shown in FIG. 6, the bills stored in the bill stacking portion (8) have a lower end portion with a claw member (49).
And it is clamped by the locking member (59), but at this time, the claw member (48).
The locking member (58) is open. However, when the next low-value banknote is conveyed by the belt (33) in this state, the motor (26) is stopped immediately after the passage of the sensor (69) of this banknote, so that the banknote has its rear end portion. Is taken in only to a position slightly separated from the upper wall of the bill stacking section (8). Thereafter, the rotary shafts (52) (53) are rotated clockwise by 90 ° to bring the claw members (48) (49) and the locking members (58) (59) into the state shown in FIG. The banknote is pushed into the banknote stack section (8) by rotating the (47) once. Then, the rotary shafts (52) (53) are further rotated clockwise by 90 °, and the upper end portion of the stored bills in the bill stack portion (8) is held by the claw member (48) and the locking member (58). As described above, the banknote stacking unit (8) is stacked while being sequentially staggered each time a low-value banknote is introduced, and one of the claw members (48) (49) is a banknote stacking unit (8).
It is configured to abut one end of the banknotes that extend inward and are stacked on top.

Next, the operation of taking out low-value banknotes from the banknote stack section (8) will be described. By the way, since the highest banknote of the banknote stack section (8) is held by one of the claw members (48) (49),
First, the switching operation of the claw members is performed in order to make the topmost banknote free. Therefore, as shown in FIG. 4, the claw member (48)
The switching operation when holding the stored banknotes by the locking member (58) and the locking member (58) is performed by rotating the rotary shafts (52) and (53) counterclockwise by 180 ° to make the topmost banknote free. The second and subsequent bills are held in a state of being held between the claw member (49) and the locking member (59) shown in FIG. On the contrary, the switching operation when the stored bill is held by the claw member (49) and the locking member (59) is performed by rotating the rotary shafts (52) and (53) 180 ° clockwise respectively. The upper banknotes are freed and the second banknote and the subsequent banknotes are held in a state of being held between the claw member (48) and the locking member (58) shown in FIG. After freeing the uppermost banknote in this way, the reduction motor (1
3) is reversely rotated to move the belt (17) in the returning direction, and the deceleration motor (28) is reversely rotated to rotate the roller (9) clockwise. Then energize the solenoid (36) to arm
(34) is rotated in the direction of arrow A, and the roller (9) is pressed against the surface of the uppermost free bill (77) to urge it toward the guide piece (23). Therefore, the banknote (77) moves while being guided by the surface of the guide wall (3) on the banknote stacking section (8) side, and the tip of the banknote (37) pushes the guide piece (23) against the spring (25) and transfers it. It reaches the guide rollers (16) and (20) of (2). And the banknote (77) is conveyed toward the insertion slot (1) by the belt (17), but when it passes the sensor (69A) the solenoid
(36) and deceleration motor (26) do not operate, bill stack part
The operation of taking out the bill from (8) is stopped. The reverse rotation operation of the deceleration motor (13) is continued until the bill (77) is ejected from the insertion slot (1) to the outside of the machine.

FIG. 12 shows a control circuit configuration in the case where the bill processing apparatus having such a configuration is applied to an automatic vending machine.
0) is a banknote processing device side circuit section, and (101) is a main body control circuit of the vending machine. The processing circuit (102) of the banknote processing device side circuit section (100) is connected to the main control circuit (101) of the vending machine, and between them, the number data of low-value banknotes, the sale end signal, the return signal, and the low-value banknote payout. A signal and a payout end signal are exchanged. Then, the processing circuit (102) gives a control signal to each drive motor and solenoid of the banknote processing apparatus through the control signal line (103) and inputs a detection signal from each sensor. The discriminating circuit (104) determines the appropriateness and type of the banknote based on the detected forces from the detection head (21), and outputs the determined banknote type data to the signal bus (105) to control the main body control circuit (101). ), And if the bill is a low-value bill at this time, a count signal is output to the counter (106). Therefore, the counter (106) counts and stores the number of low-value banknotes in the banknote stack section (8), and the main body control circuit (101) is a processing circuit.
It holds the number data, which is periodically transmitted from (102).

In the control circuit, when the bill inserted from the insertion slot (1) is determined to be a low-value bill by the identification circuit (104),
A count-up signal is supplied to the counter (106), the number of low-value banknotes is incremented by 1, and low-value banknotes are automatically supplied to the banknote stacking unit (8) of the banknote processing apparatus. Then, when the type data from the identification circuit (104) indicates that the inserted banknote is a low-value banknote, the main body control circuit (101) adds and counts this amount to the inserted amount and performs predetermined sales control. Further, when the main body control circuit (101) indicates that the inserted banknote is a high-value banknote by the type data from the identification circuit (104), the main body control circuit (101) determines whether to accept the high-value banknote. Judgment is made in relation to the number data of the low-value banknotes of the section (8) and the selling price of the product. That is, if there is no low-value banknote corresponding to the difference between the inserted banknote amount and the selling price, the main body control circuit (10
1) is a processing circuit for the return signal (102)
Send to. When this return signal is introduced, the processing circuit (10
In 2), similarly to the case where the inserted bill is returned improperly, a reverse rotation signal is output to the reduction motor (13) through the control signal line (103) to return the inserted high bill. Then, when it is acceptable, the inserted high-value banknotes are introduced into the banknote storage unit (7), and the main body control circuit (101) performs the predetermined sales control by adding and counting the banknote amounts. When the vending machine sells a product and needs a change, the main body control circuit (101) transmits a low-value banknote payout signal to the processing circuit (102). At this time, the processing circuit (102) outputs a series of signals necessary for taking out the low-value banknotes from the banknote stack section (8) by the roller (9), which is a takeout device, and guiding them to the transfer device (2). It is output to the bill processing device by (103). That is, the processing circuit (102) outputs a drive signal to the deceleration motor (54) that drives the rotating shafts (52) (53) to make the topmost banknote of the banknote stack section (8) free, and the solenoid (36 ) And a reverse rotation signal to the deceleration motor (26) to rotate the roller (9) clockwise. Then, the processing circuit (102) inserts (1) the low-value banknote taken out from the banknote stack section (8) by the transfer device (2).
The control circuit includes a control means for reverse transfer to the control signal line (103) during the control operation.
Output a reverse rotation signal to the deceleration motor (13) through the belt (1
Move 7) in the return direction. Then, it is confirmed that the bill transferred in reverse by this operation is not a proper low-value bill.
04) signal bus (105), the processing circuit (10
2) stops outputting the reverse rotation signal and outputs a normal rotation signal to the deceleration motor (13) through the control signal line (103) in the same manner as when the high-value banknotes are stored as appropriate and the transfer device (2 ) Is carried out and the bill is stored in the bill storing section (7). Then, the processing circuit (102) again takes out the low-value banknotes from the banknote stack section (8) by the roller (9) which is a takeout device and transfers the low-value banknotes (2).
Control signal line (103)
To the banknote processing device. Further, when it is indicated that the bills to be reversely transferred are proper low-price bills, the reverse rotation signal is continuously output to the deceleration motor (13) through the control signal line (103) to reverse the transfer device (2). The low-value banknotes are transferred and discharged from the insertion slot (1). That is, the processing circuit (102) also includes control means for continuing the reverse transfer or switching to the operation for accommodating the high-value banknotes, depending on the determination of the suitability of the low-value banknotes by the identification circuit (104) during the reverse transfer. On the other hand, the low-value banknote insertion slot (1)
When it is discharged from the processing circuit (102), the processing circuit (102) outputs a countdown signal to the counter (106) to subtract "1" from the number of low-value banknotes and outputs a payout end signal to the main body control circuit (101). When the payout end signal is input to the main body control circuit (101), the discharged bill amount is subtracted from the calculated change amount, and the above-described operation is repeated when the lower bill amount needs to be paid out.

(F) Effect of the Invention According to the present invention, the bill identifying unit discriminates the properness and type of the bills that are transferred backward from the bill stack unit to the insertion slot by the transfer device due to the generation of the low-value bill payout signal, If it is determined that it is not a low-value banknote, the transfer device stops the reverse transfer and performs the forward transfer, and receives the banknote in the banknote storage unit of the high-value banknote as in the case of receiving the high-value banknote, and thus the banknote stack unit. Even if a bill different from the low-value bill is mixed, or if there is a bill that is damaged for some reason and loses its value as a bill, or if multiple low-denomination bills are stacked on top of each other, the reverse Even when they are transferred, these banknotes can be stored in the banknote storage unit for high-value banknotes and can be prevented from being discharged to the insertion slot.
