Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bill accepting device used in a vending machine or the like, and a bill accepting control method in the bill accepting device.

The banknote acceptance device includes at least a banknote identification device that has a function of identifying authenticity of inserted banknotes, accepting genuine banknotes, and returning counterfeit banknotes, and a storage device for storing accepted banknotes. . In order to be able to return the banknotes once accepted as necessary, the storage device must be configured as a temporary storage device, ie, an escrow device. but,
Up to now, only one temporary holding device has been installed in a banknote accepting device that can handle multiple denominations of banknotes (for example, Japanese Patent Application No. 125020/1983), and it is difficult to mix input banknotes of different denominations. I was trying to put it on hold. For this reason, it has been impossible to reserve specific banknotes and allow them to be used as change.

An object of the present invention is to provide a bill accepting device that can effectively temporarily hold input bills, and also to provide a method for effectively controlling bill accepting using such a bill accepting device. There is a particular thing. Specifically, the present invention aims to provide a bill receiving device that makes it possible to dispense predetermined low-denomination bills as change, and furthermore, to make it possible to dispense bills of other denominations as change. This is what I am trying to do. Another object of the present invention is to provide a bill acceptance control method that can prevent bill fraud in the bill acceptance device described above.

(5) A banknote acceptance device that achieves the various purposes described above includes a plurality of holding devices that are capable of holding banknotes accepted as genuine notes by a banknote recognition device and returning the held banknotes, and a banknote recognition device that and a path switching device that selectively connects a banknote path from the device to each of the holding devices. By providing a plurality of holding devices, at least one of them can be reserved exclusively for banknotes of a predetermined low denomination, and it is also possible to dispense the held banknotes of the denomination as change. Also,
Input banknotes of other denominations can be temporarily held in another holding device, and can be easily returned if a request for refund of the deposit is made.

A stocker device is provided to further increase the amount of banknotes stored. Generally, when the holding device becomes full, the inserted banknotes are stored in the stocker device. Banknotes stored in the stocker device cannot be automatically returned. Fraud in which genuine notes are stolen by inserting counterfeit notes and requesting refunds can be prevented by retaining the inserted banknotes in the above-mentioned holding devices and then returning them. So (6) I can do it. However, if unfortunately a counterfeit bill is inserted when the holding device is full, the counterfeit bill will be stored in the stocker device.
Genuine bills are returned from the holding device.

In order to prevent such inconvenience from occurring with relatively high denominations, according to the present invention, input banknotes of predetermined low denominations are reserved exclusively in the first holding device, and other than /''≦, Control is performed such that the two types of input banknotes are held in the second holding device, and the held banknotes of the second holding device are transferred to the stocker device once (every time a proboscis sales operation is performed). , second
The second holding device always holds only the amount of banknotes that are inserted each time. Therefore, when the second holding device is full, the inserted banknotes that should be held in the second holding device are no longer stored in the stocker device, making it difficult to request a refund. Sometimes, it is possible to return the inserted banknotes themselves.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, the banknote acceptance device includes a banknote identification unit 11 that identifies the authenticity of banknotes inserted from the insertion D1[), and a banknote that is determined to be a genuine banknote by this recognition unit 11 to be temporarily held (
The present invention includes an escrow section 12 for holding banknotes in a state where they can be automatically returned, and a stocker section 13 that is provided between the identification section 11 and the escrow section 12 and for storing accepted banknotes in a state where they cannot be automatically returned. It is growing. The escrow section 12 includes two banknote holding devices 12-1 and 12-2.
According to the denomination identification result of the inserted banknote in step 1, a predetermined low-denomination banknote (for example, 1,000 yen bill) is held in the first holding device 12-1, and other banknotes (for example, 5,000 yen note and 10,000 yen note) are held in the first holding device 12-1. ) is held in the second holding device 12-2. The inserted banknotes are placed in the first or second holding device 12-1.12- depending on the denomination.
A flapper 64 and a renoid SQL are provided in order to perform branching control leading to either one of the two directions.

A banknote sensor P1 is provided near the entrance of the banknote path 1 in the banknote identification section 11, and a banknote sensor P2 is provided near the exit of the path 1. The banknote identification unit 11 is further provided with sensors for detecting the authenticity of banknotes, but this point is not the gist of the present invention and will therefore be omitted. Sensor P1. P2 is 1 provided across passage 1.
This is a photosensor consisting of a pair of light emitting element and light receiving element, and the same applies to sensors P3 to P7, which will be described later.

The banknote transport motor M1 in the recognition unit 11 controls the feeding of banknotes in the recognition unit 11, and transports banknotes in the receiving direction (towards the stocker unit 13) when rotating in the normal direction, and when rotating in the reverse direction. At this time, the banknote is conveyed in the return direction (towards the insertion slot 10). When the inserted bill is determined to be a genuine bill, it is accepted, and when it is determined to be a counterfeit bill, it is returned.

The exit of the passage 1 (the opening on the sensor P2 side) communicates with the banknote passage 2 of the stocker section 13. The vertical portion of the banknote passage 2 in the stocker section 13 is connected to the push plate 4 of the reciprocating mechanism 14 and the long channel member 5a.

5b), the length of which approximately corresponds to the length of the banknote. Banknote passage 2 of stocker section 13
A banknote sensor P6 is provided near the entrance of the bank. Additionally, banknote sensors p4.
p5 is provided.

The exit of passage 2 is connected to banknote passage 3 of escrow section 12 (9) It's working.

In the stocker section 16, a reciprocating mechanism 14 and a bill conveyance device are provided on one side of the vertical portion of the bill path 2, and a bill accumulating section 15 is provided on the other side. The banknote storage unit 15 includes two long channel members 5a and 5b (see FIG. 2) vertically arranged side by side with a predetermined interval slightly narrower than the width of the banknotes, and a banknote surface. It has a somewhat larger size and includes a banknote compression plate 6 vertically arranged parallel to the channel parts 5a and 5b. Although the channel members 5a and 5b are fixed, the banknote compression plate 6 is movable in parallel in a direction perpendicular to the plate surface, and the channel member 5a is always compressed by the action of a plurality of appropriately placed compression springs PS.

It is pressed in the direction of 5b.

The reciprocating mechanism 14 includes a push plate 4 substantially parallel to the banknote compression plate 6, a drive plate 7 fixed to the push plate 4 at a substantially right angle, and a motor M4 for reciprocating the push plate 4 and the drive plate 7. Power transmission mechanism (belt 8, goo') 9 a', '9
b). In FIG. 1, the drive plate (10) 7 is shown cut away. The motor M4 is fixed at a predetermined location, and this rotation is transmitted via the belt 8 to the pulley 9b. No! J
9a and 9b are arranged parallel to the drive plate 7, and protrusions 17 and 18 provided on the pulleys are respectively inserted into two elongated holes 19 and 20 provided on the drive plate 7. When the pulleys 9a and 9b rotate in accordance with the rotation of the motor M4, the projections 17.18 move in a circular motion, and accordingly, the projections 17.18
The υ drive plate 7 reciprocates in the direction of the plate surface (left and right) by engagement with the long holes 19 and 20, and as the drive plate 7 moves, the push plate 4 is pinched in the direction perpendicular to the plate surface. It reciprocates in the direction of the banknote compression plate 6 (left and right). Sea IJ9a.

When 9b rotates once, the drive plate 7 and the push plate 4 perform one reciprocating left and right reciprocation. In a normal state, the push plate 4 is located at the farthest position from the banknote storage section 15 as shown, and a vertical portion of the banknote path 2 is formed between the push plate 4 and the channel members 5a, 5b.

The length of the push plate 4 approximately corresponds to the vertical length of the banknote, but the width is narrower than the width of the banknote and also narrower than the distance between the two channel members 5a and 5b. Therefore, when the push plate 4 reciprocates left and right in the direction of the bill storage section 15 by one rotation of the motor M4, the push plate 4 can pass through between the two channel members 5a and 5b. It has become.

In the stocker section 13, the banknote conveyance device includes a motor M3.
and 7'-IJ21 to which the rotation of motor M6 is transmitted.
The rotation of this pulley 21 is transmitted through the belt 22 to five pulleys (only one of which is labeled 23), and among the five pulleys, the direction of rotation is the same (three predetermined pulleys) It includes three pairs of banknote conveyance rollers 24°25.26 provided coaxially.Banknote conveyance roller 2
4 to 26 are, for example, rubber rollers provided with protrusions around the periphery. Referring to FIG. 2, the pair of rollers 25 consists of two rollers arranged at a distance corresponding to the two channel members 5at5b. Rotation of motor M6 is caused by pulley 21
and is transmitted to the five pulleys 26 via the belt 22,
The banknote conveying rollers 24 to 2 are connected via three pulleys among them.
6 as rotations in the same direction. Both sides of the banknote are sandwiched between the banknote conveying rollers 24 to 26 and the channel members 5a to 5b, and the banknote is conveyed according to the rotation of the rows 224 to 26. The motor M6 can rotate in forward and reverse directions, and can transport banknotes in the passageway 2 in either the receiving direction or the return direction.

The bill passage 6 of the escrow section 12 branches into two at the point 34, one leading to the first holding device 12-1 and the other leading to the second holding device 12-2. . A banknote transport roller 65 is provided in front of the branch point, and this roller 65 is driven by a motor M2 to transport the banknotes passing through the branch point without delay. Furanogu 34 installed at the point
normally closes the passage to the second holding device 12-2 and opens the passage to the first holding device 12-1, as shown by the solid line, but when the solenoid SQL is energized, the passage to the second holding device 12-2 is closed, as shown by the broken line. Switching to the position shown, the path to the first holding device 12-1 (13) is closed and the path to the second holding device 12-2 is opened. Bill sensors p6 and p7 are provided at the entrance of each holding device 12-1 and 12-2, respectively.

The holding devices 12-1 and 12-2 have the same configuration, and include banknote guiding belts 36a, 36b, and belts 36a, 36b, and 36b.
A first drum 37a, 57b has one end of the belt 36b fixed, and a second drum 38a is parallel to the first drum and has the other end of the belt fixed.

38b, and a motor M5.38b for rotationally driving the second drums 38a, 38b. Contains M6.

The guide bells 36a and 36b are, for example, helical springs, so that a restoring force acts in the direction in which they are wound around the first drums 37a and 37b. Motor M5. When M6 is rotated forward, the four roots 36a and 66b are connected to the second drum 38.
a, 38b. Motor M5. When M6 is reversed, the belts 36a and 36b are connected to the second drum 38aj3.
8b, and is rewound onto the first drum 37&, 37b by the self-righting force by the amount that has been fed out. The banknotes inserted into the insertion slot 10 pass through the passages 1, 2.3, are branched to one of the holding devices 12-1, 12-2 at the flapper (14) 64, and are transferred to the second drums 38a, 38b. It enters between the winding body with the core and the belt,
5, and is tightly wound around drums 38a and 38b together with belts 36a and 36b in response to normal rotation of M6. When discharging banknotes wound up on the second drums 38a and 38b, the motors M5 and M6 are reversed and the belts 36a and 36
b is fed out, and the banknotes are discharged in the direction of path B through the branching point. Of course, the motors M5 and M6 are driven selectively depending on the switching position of the flapper 64. Each motor M5. The timing of driving start and stop of M6 is determined by banknote sensor p6. It is controlled according to the output of p7. Ennotei detector ES i in connection with motor M5
and a full detector FS1 are provided, and associated with the motor M6 are an ennoti detector ES 2 and a full detector FS 2.
is provided.

When the motors M5 and M6 are at their initial positions and no banknotes are wound up on the tabs 38a and 38b, the ennote detectors ES1 and ES2 operate to detect the respective empty notes. When the motors M5 and M6 make a predetermined rotation in the forward rotation direction from the initial position, fullness detectors FS 1 and F provided via a gear down mechanism (not shown) are activated.
S2 is activated and detects that it is full. - As an example, the full detector FSj is activated when about 20 banknotes are wound around the drum 38a, but this number may be set to the number of banknotes.

Bills inserted from the insertion slot 10 are introduced into the escrow section 12 through passages 1 and 2, and the inserted bills are temporarily reserved. When introducing the inserted banknotes to the escrow section 12, the reciprocating mechanism 14 of the stocker section 16 does not operate, and only the banknote transport device (motor M3, etc.) operates, and the input banknotes given from the banknote recognition section 11 are guided to the stocker section 16. It passes through the passage 2 and is led to the escrow section 12. Banknote storage section 1 of stocker section 16
5 stores the inserted banknote given from the banknote identification section j1 or the banknote discharged from the escrow section 12. The operation of storing banknotes in the banknote storage section 15 of the stocker section 16 is performed as follows.

When a banknote to be stored is fed from the banknote recognition section 11, the banknote transport motor M3 of the stocker section 13 is rotated in the normal direction to draw the banknote into the vertical portion of the passage 2. On the other hand, when banknotes to be stored are fed from the escrow section 12, the motor M3 is reversely rotated to draw the banknotes into the vertical portion of the passage 2. When the bill to be stored has completely entered the vertical portion of the passage 2, that is, the passage portion between the push plate 4 and the channel members 5a, 5b, the motor M3 is stopped and the bill is stopped at that point. When the motor M3 is rotating in the normal direction, the sensor P4, which had been detecting the banknote, no longer detects the banknote, which indicates that the banknote has completely entered the vertical portion of the passageway 2. On the other hand, when the motor M6 is being rotated in the reverse direction, the sensor P5, which had been detecting banknotes, no longer detects banknotes, and the above-mentioned fact becomes clear. After stopping the motor M3, the motor M4 of the reciprocating mechanism 14 is rotated once to store the banknotes in the vertical portion of the passage 2 into the banknote storage section 15. A schematic diagram illustrating this storage operation is shown in FIG.

, (17) FIG. 3 is a schematic diagram corresponding to FIG. 2, and (,) indicates the storage state when not a single bill is accumulated between the bill compression plate 6 and the channel members 5a and 5b. The banknote 29 is shown being fed into the vertical section of the passageway 2 for the first time. When motor M4 is rotated once in this state, it will change from 0 degrees to 1 degree.
In a stroke of 80 degrees, the pushing plate 4 moves in parallel in the direction of the banknote compression plate O (in the direction of the arrow), and pushes the banknote 29 in the passage 2 in the direction of the compression plate O. The pressed bill 29 is pressed on the pressing plate 4 while looking at the banknote 29.
At the same time, it passes through between the channel members 5a and 5b and comes into contact with the compression plate 6. As shown in FIG. 3(b), the push plate 4
With the movement in the direction of arrow A, the compression plate 6 and the banknote 29 sandwiched between the push plate 4 and the compression plate 6 are compressed by the compression spring ps.
moves in the direction of arrow A (in the direction of compressing the spring PS) against the repulsive force of. Mo + M4 from 180 degrees to 660
When the push plate 4 rotates completely, the push plate 4 moves in the opposite direction to that described above (in the direction of arrow B), and the compression plate 6 and the bill 29 return together with the push plate 4 due to the restoring force of the compression spring PS. When both sides of the banknote 29 come into contact with the channel members 5a and 5bKa, the (1
8) The movement of the banknote 29 and the compression plate B causes the channel member 5a,
5b, after which only the push plate 4 moves according to the rotation of the motor M4, and when the motor M4 completes one rotation, the push plate 4 returns to its original position (the position forming the vertical part of the passage 2). return.

The above is one cycle of banknote storage in the stocker section 16, and the banknotes 29 are finally stored between the channel sections 15a, 5b and the banknote compression plate 6, as shown in FIG. Ru. The banknote 29 is tightly held between the channel members 5a, 5b and the compression plate 6 by the compression spring psO force.

By repeating the above one cycle of banknote storage, the banknotes 60 to be newly stored (see FIG. 3(d)) are added next to the banknotes 61 already stored between the compression plate 6 and the channel members 5a and 5b. will be done. In other words, Figure 3 (
As shown in e), the push plate 4 adds new banknotes 30 next to the banknotes 61 by its outward movement, and pushes these banknotes 30, 31 and the compression plate 6 together in the direction of the arrow. Thereafter, when the push plate 4 moves back, the new banknote 60 will be sandwiched between the old banknote 31 and the channel member 5 a e 5 b. In this way, between the banknote compression plate 6 and the channel members 5a and 5b, the banknotes are horizontally stacked in an upright state, compressed, and accumulated.

In the reciprocating mechanism 14, it is preferable to provide a sliding support base 62 (FIG. 1) below the driving plate 7 or at an appropriate location to slidably support the driving plate 7. Similarly, in the banknote storage section 15, an appropriate base plate 66 (FIG. 1) is provided below the banknote storage area and the compression plate B, and the channel member 5
It is preferable that the lower part of the banknote and the lower part of the compression plate B be freely supported while supporting the parts a and 5b in a fixed manner.

When automatically returning banknotes held in the escrow section 12 toward the insertion slot 1o, the motors Ml or M6 and M2. M3
．． Reverse Ml and eject the banknote through passage 3,2°1. When storing banknotes stored in the escrow unit 12 in the banknote storage unit 15 of the stocker unit 13 by inventory operation, reverse the motors M5 or M6 and M2 and M6.
When one banknote is stored in the vertical portion of the passage 2 of the stocker section 13, these reversals are stopped, and then the reciprocating mechanism 14 is operated in the same manner as described above to store the banknote in the storage section 15.

In this manner, during inventory operation, the banknotes held in the escrow section 12 are sequentially transferred one by one to the storage section 15 of the stocker section 16. Of course, the ejection of banknotes from the escrow section 12 is performed in accordance with the switching position of the above-mentioned pass and franc 34. This is performed alternatively from one of the second holding devices 12-1 and 12-2.

There are several possible methods for controlling the acceptance of banknotes.

For example, banknotes of a predetermined low denomination are accepted into the first holding device 12-1 until the first holding device 12-1 is full, and when the banknote is full, they are stored in the stocker section 13, while bills of other denominations are input. In this method, the banknotes are once received in the second holding device 12-2, and when one sales operation is completed (or may be started), the banknotes are discharged from the device 12-2 and stored in the stocker section 16. According to this method, not only can the predetermined low-denomination banknotes held in the first holding device 12-1 be used as change, but also if the purchase is canceled after the banknotes have been inserted (21), the banknotes can be used as change. There is an advantage that the high-value banknotes themselves can be returned from the second holding device 12-2. Therefore, it is possible to make it impossible to steal the same amount of money by inserting and canceling a cleverly forged high-value banknote with another banknote.

Such an acceptance control operation is shown in a flowchart as shown in FIG.

In block 39, it is checked whether sensor P1 is turned on. It should be noted that turning on the sensors P1 to P7 indicates a state in which a banknote is detected. When a bill is inserted into the bill insertion slot 10, the sensor P1 is turned on. When the sensor P1 is turned on, the motor M1 starts rotating in the normal direction. As a result, the inserted banknotes are conveyed through the passage 1. During this process, the authenticity of the inserted banknote is determined, and if it is determined to be a counterfeit banknote, the motor M1 is temporarily stopped, then reverse starts, and when the sensor P1 changes from on to off, the motor M1 is stopped (block 40, 41. 42).

As a result, the counterfeit bill is returned to the insertion slot 10.

(22) When it is determined that the bill is genuine, the process proceeds to block 43, and the sensor P
3 is turned on. If YES, it means that the tip of the inserted banknote has entered the passage 2 of the stocker part B, and based on this, the motor M3 starts normal rotation. Due to the forward rotation of the motors M1 and M3, the banknotes are transferred to the identification section 11.
From then on, they are transferred into the stocker section 16. Eventually, when the rear part of the banknote passes past sensor P2, sensor P2 is turned off and motor M1 is stopped by the process of block 44. In block 45, it is checked whether the denomination of the inserted banknote determined to be a genuine note by the banknote identification unit 11 is a predetermined low denomination (for example, 1,000 yen) to be stored in the first holding device 12-1. . If YES, block 46 (see section 5 for details)
The process shown in FIG.

The case where the block 45 is YES and a 1,000 yen bill is inserted will be described with reference to FIG. In the first decision block 48 in block 46, it is checked whether the full detector FS1 of the first reservation device 12-1 is on (detects full), and if NO, the block 49 The subsequent processing is performed to store the inserted banknotes in the first holding device 12-1. If YES, the processing from block 50 onward is performed to store the inserted banknotes in the banknote storage section 15 of the stocker section 16. The judgment of this block 48 is based on the motor M
The forward rotation drive of No. 3 ensures that the rear end of the bill is moved from the position of sensor P2 to the position of P4.

First, the route of No in block 48 will be explained.

As the motor M3 continues to rotate normally, the banknote is conveyed through the passage 2, and when the leading edge of the banknote eventually reaches the exit of the passage 2, the sensor P5 is turned on and the block 49 becomes YES. Based on this, the motor M2 starts rotating normally. Since solenoid SQL remains deenergized, flapper 64 opens a path to first retention device 12-1. Therefore, the 1,000 yen bill is transferred to the roller 35 driven by the motor M2.
According to the forward rotation of , it is guided to the first holding device 12-1. In block 51, it is checked whether the sensor P6 provided at the entrance of the branch passage to the first holding device 12-1 is turned on. When the tip of the bill reaches the P6 position, P6 turns on,
Based on this, the motor M5 starts rotating normally. Motors M3, M2.

By normal rotation of the M5, the banknotes pass from the path 2 of the stocker section 13 to the path 6 of the escrow section 12 and the branch point by the flapper, and are transferred to the second drum 38 of the first holding device 12-1.
It is fed between the winding body of A and the belt 36a, and is wound together with the belt 66a on the winding body. If the trailing edge of the bill touches sensor P5 too much, P5 will turn off.
Stop motor M6. Furthermore, the rear end of the bill is connected to sensor P6.
If too many points are passed through, P6 will turn off and motor M2 will turn off.
After stopping and waiting for a predetermined time, block 52
to stop motor M5. This waiting time is a short period of time required for the rear end of the bill to move from the position of the sensor P6 to near the winding body of the second drum 38a.

The route of YES in block 48 will be explained.

As the motor M3 continues to rotate normally, the banknote is conveyed through the passage 2, and when the rear end of the banknote eventually passes the sensor (25) P4, the sensor P4 is turned off and the block 50 becomes YES. Based on this block 53
The motor M6 is stopped by the process.

In this state, the inserted banknote is located at a position that exactly corresponds to the push plate 4, and is stationary at that position.

Next, in block 54, the motor M4 of the reciprocating mechanism 14 is
Performs rotational drive processing. As a result, the above-mentioned Tota,
The push plate 4 reciprocates once to push out the banknotes in the passage 2 toward the banknote storage section 15 and store them in the banknote storage section 15.

As described above, if the number of judicial bills in the first holding device 12-1 has not reached the predetermined full number, the input banknotes (thousand yen bills) of a predetermined low denomination are stored in the device 12-1, When the predetermined number of bills is full, the inserted bills are stored in the bill accumulating section 15 of the stocker section 13.

If the inserted banknote is not of the predetermined low denomination (1,000 yen bill) that should be stored in the first holding device 12-1, that is, a 5,000 yen bill or a 1,000 yen bill.
In the case of a 10,000 yen bill, block 45 is NO, and block 4
Proceed to step 7. In block 47, (26) solenoid SQL is set to energization mode, and flapper 6 is activated.
4 to the position indicated by the broken line, and the passages 2 and 6 are connected to the second holding device 12-2. The next processing in block 55 consists of the procedure shown in FIG.
The processing is almost the same as the processing from blocks 49 to 52 (FIG. 5), and whereas the processing from blocks 49 to 52 controls the motor M5 according to the output of the sensor P6, the processing from block 5
5 (Fig. 6), motor M6 is activated according to the output of sensor P7.
The only difference is that it is controlled. In other words, the inserted banknote of 5,000 yen or 10,000 yen is conveyed through the passage 2 as the motor M3 rotates normally, and the tip of the banknote eventually reaches the sensor P5.
When detected by
The banknotes pass through the Furano'e64 position switched to the broken line position by the motor M2 and are transferred to the second holding device 12.
-2, and when the leading edge of the bill is detected by sensor P7, motor M6 starts rotating normally, and finally, when the bill is wound around drum 38b together with belt 36b, motor M6 stops. In this way, when the input banknotes have been stored in the second holding device 12-2, the solenoid SQL is deenergized by the process of block 56, and the furano
64 returns to its normal position.

Returning to FIG. 4, the circulation routine when block 69 is No (waiting for further bill insertion) will be described. Block 57 checks to see if the refund button has been pressed. Block 5 if refund button is not pressed
Proceeding to step 8, it is determined whether or not the vending operation (commodity dispensing operation according to the input amount and the purchaser's selection) has just ended (or may start) in the vending machine equipped with this bill accepting device. If the process has not been completed, the process goes through the No route and returns to block 39, where preparations are made to accept further input banknotes. When the selling operation is completed, the answer in block 58 becomes YES, and the high-value inserted banknotes temporarily held in the second holding device 12-2 are stored in the banknote storage unit 15 through the processing from block 59 onwards.

In block 59, the solenoid SQL is set to the energizing mode, the flapper 64 is switched, and the second holding device 12-2 is activated.
Passage 3, 2. Leads to. Block 60 checks whether the empty detector ES2 is on. ES when no banknotes are held in the second holding device 12-2
2 is on and off.If the banknote is being held, it is off.

If ES2 is off, the processing of block 61 causes motor M6. M2゜M3 reverse start position, drum 38b
Ejects the banknotes that were rolled up. When sensor P7 falls from on to off (when the rear end of one ejected bill passes past sensor P70), block 62 becomes YES and motor M6 is stopped.

Next, when sensor P5 falls from on to off, block 66 becomes YES and motors M2 and M3 are stopped. In this state, one bill discharged from the second holding device 12-2 is located in the vertical portion of the passage 2. Therefore, by driving the motor M4 one rotation through the process of block 64, the banknotes can be stored in the storage section 15. When the process of block 64 is completed, the process returns to block 60, and it is checked whether the second holding device 12-2 is empty (29). In this way, the processes of blocks 61 to 64 are repeated until all the banknotes in the second holding device 12-2 are discharged, and the held banknotes are stored in the storage unit 15 one by one. Once the holding device 12-2 is empty, the process moves to block 65, where the solenoid SQL is deenergized and returned to its normal position. If the refund button is pressed, a refund process is performed in block 66. In the refund process, first, the motor M5 of the first holding device 12-1
and motor M2. M3. Reverse Ml and insert the inserted number of 1,000 yen bills from the first holding device 12-1 into the insertion slot 10.
Return it to. Next, the solenoid SQL is energized to switch the flapper 64, and the motors M6, M2. M3. Ml
The banknotes held in the second holding device 12-2 are all returned toward the insertion slot 10 by reversing the banknotes. Encity detector ES
2 is turned on, sensor p7. p5. p4. Based on the output of motor M6. M2. M3. ML is stopped one by one, solenoid SQL is deenergized, and the refund process is completed.

According to the above-mentioned rules and the acceptance control method shown in FIG. The inserted banknotes are temporarily held in the second holding device 12-2 only while one selling operation is being performed, and immediately transferred to the storage unit 15 when one selling operation is completed.

As another example of the acceptance control method, as for the first holding device 12-1, all 1,000 yen is stored until it is full in the same way as described above.
As for the second holding device 12-2, it is conceivable to store 5,000 yen and 10,000 yen bills until it becomes full, similar to the case with the second holding device 12-1. This method eliminates the routine of blocks 58 to 65 in FIG. This can be realized by changing 55 to the same process as 46 (when FS and 2 are on, they are stored in the storage unit 15). In this way, the second
Since the holding device 12-2 can hold a relatively large amount of banknotes, there is an advantage that the total amount of banknotes that can be stored increases. However, when the second holding device 12-2 is full and all the counterfeit bills (31) are inserted, the counterfeit notes are stored in the storage section 15, and if the refund button is pressed at that time, the second holding device 12-2
2. The inconvenience of having genuine bills returned may occur, and since these are high-value bills, such fraud can cause great damage. In this regard, according to the example of FIG. 4 mentioned above,
Since the inserted banknote itself is always held in the second holding device 12-2 for high-value banknotes, the above-mentioned inconvenience does not occur.

As yet another example of the admission control method, the first holding device 12-
1, hold a predetermined low denomination denomination (1,000 yen bill) in the same way as above,
The second holding device 12-2 holds another predetermined denomination (for example, a 5,000 yen bill) until it is full in the same way as the second holding device 12-1, and the remaining denominations (for example, a 10,000 yen bill) One possible method is to store it in the storage section 15. The procedure for controlling the acceptance of this waste can be easily implemented from the above description, so it will not be described in detail.

As yet another example of the acceptance control method, there is a method in which a dedicated holding device is provided for each denomination of banknotes, and each holding device stores banknotes of a predetermined denomination until it is full.

(32) This makes it possible to pay out all banknote denominations as change. An example of the escrow section 12 is shown in FIG. 7 with three holding devices 12-1.12-2.12-3. Individual holding devices 12-1 to 12-6
has the same configuration as that shown in FIG. 1, and includes a banknote guide belt, a first drum with one end fixed, a second drum with the other end fixed, and a motor M5 that drives the second drum. , M6, M7, and soil detector ES
1 to ES 3 and full detectors FS 1 to FS 3.

The flapper 34-1 normally connects the passage 3 to the first holding device 1.
2-1, the passage 6 is switched by the energization of the solenoid 5QL1, and the passage 6 is connected to the second and third holding devices 12.
-2. Leads to 12-3.

Furano" 34-2 is always in the second holding device 12-2
The inlet of the third holding device 12-3 is opened, and the inlet of the third holding device 12-3 is closed, and the switch is switched by the energization of the solenoid SQL 2, blocking the second holding device 12-2, and closing the inlet of the third holding device 12-6.
open. Passage B is provided with banknote rollers (33) 35 driven by motor M2 in the same manner as described above. Furthermore, banknote sensors P6 to P8 are provided at the entrances of each of the holding devices 12-1 to 12-3 for the same purpose as described above.

An example of the acceptance control method by the escrow section 12 in FIG.
As shown in the figure. Block 39 for determining “rP1 ON”
The steps from to block 44 for stopping motor M1 are the same as in FIG. In block 45A, the denomination of the inserted bill is confirmed, and if it is a 1,000 yen bill, the process proceeds to block 46-1.
The storage device 12-1 is stored in the storage device 12-1. 5
If it is a 1,000 yen bill, the process goes to 46-2 via block 67, and processing for storing it in the second holding device 12-2 is performed.

If it is a 10,000 yen bill, proceed to 46-3 via block 68,
Processing is performed to store it in the third holding device 12-6. Block 67 sets solenoid SQL 1 to the energized mode and communicates passageway 3 to second retention device 12-2. In block 68 both solenoids SQL 1 and 5OL
2 to the energized mode and the passage 3 to the third retention device 1.
This leads to 2-6. Block 69 deactivates 5OLI,
70(34) Deactivates sor, i and 5oL2. each block 4
6-1 to 46-3 perform the same processing as that of block 46 shown in FIG. However, block 46-2.4
6-3-r is shown in FIG. 5 (7) FS1, P6°M5 is ES2. ES3゜P7. P8. M6.
They are each replaced by M7. In addition, in FIG. 8, block 39
In the NO loop, the processing in blocks 57 and 66' is performed, but the processing corresponds to blocks 58 to 65 in FIG.
will not be carried out. However, block 66' is slightly different from block 66 in FIG. The third holding device 12-2, 12-6 also performs control to discharge held banknotes one by one, which are in excess of the number to be returned. In this way, each holding device 12-1 to 12-6
A plurality of banknotes can be stored for each denomination, and banknotes of each denomination can be dispensed as change. still,
The number of paid bills can be counted using sensors P6 to P8.

As explained above, according to the present invention, since a plurality of holding devices capable of automatically returning held banknotes are provided,
Inserted banknotes can be held individually according to their denominations, which is convenient when making a refund, and the held banknotes can also be used as change.

It is still possible to eliminate fraudulent use of counterfeit notes.
