DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a bill handling apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of the apparatus of the embodiment, and FIG. 2 shows a partial perspective view. The main components of the device are a validator (discrimination device) 10 equipped with an electronic control unit (not shown) that determines authenticity based on a detection signal of an identification element of the inserted banknote 1, and an operation from the electronic control unit. A drive source having a motor 50 that rotates normally or reversely in response to a signal, a conveyance device 20 that conveys the banknote 1 that has been operated by the rotation output of the drive source and passed through the validator 10, and a rotation device that outputs the rotation output of the drive source. And a bill pushing device 30 for pushing the received bill 1 into the box 41 and storing the bill 1 in synchronization therewith. Further, the bill pushing device 30 is provided with a one-way clutch mechanism so that the transport device 2 can be operated when the drive source is normally rotated.
0 operates in the direction in which the banknote 1 is conveyed, but the banknote pushing device 30 idles and stops by the one-way clutch mechanism, and when the drive source rotates in the reverse direction, the bill pushing device 30 receives this output and operates forward. , Bill 1 in box 4
It is configured to be pushed into 1.

More specifically, each part of the validator 10 is detachably fixed to the upper part of the case 2, has a bill insertion slot 11 on the front side thereof, and a transport passage 12 is formed following the insertion slot 11. A detection means for detecting various elements for determining the authenticity or defective bill of the banknote 1 being passed is arranged in the middle of the transport passage 12. Usually, the judgment factors include the paper quality, color, and printing ink components of ordinary bills. As one of the detection means of these various determination elements, a sensor for reading the printing pattern of the banknote is arranged in the middle of the transport passage 12. The detection sensor for reading the pattern is composed of a pair of light-emitting and light-receiving elements, and these elements are arranged orthogonally to the conveying direction so as to face each other above and below the passage, and a bill is passed between both elements. That is, by irradiating the bill passing between both elements with light to detect the optical characteristics due to light and dark, or by arranging a magnetic head, the magnetic characteristics of the passing bill are detected, and this detection signal is detected. The authenticity of the banknote is judged by sending it to an electronic control unit (CPU) by a microcomputer and performing various controls based on the detection signal to recognize the printing pattern.

The carrying device 20, the bill pushing device 30, and the stacker (banknote storing portion) 40 are housed and mounted in one case 2. Of these, the transfer device 20 includes the first and second transfer devices connected to the transfer passage outlet 13 of the validator 10.
Having the transport guides 21 and 22, the transport guide 21 on the inlet side
A belt 23 made of rubber or the like is peeking in the middle of. That is, the banknote 1 sent from the banknote outlet 13 of the validator 10.
Is brought into contact with the belt 23, and the banknote is pulled in by a frictional force with the first transport guide 21 side. Belt 2
An endless member 3 is wound between a pair of transporting pulleys 24A and 24B and rotates in a counterclockwise direction as shown in FIG. In the vicinity of the intersection of the first conveyance guide 21 and the belt 23, a pair of sensors 26 facing each other are sandwiched between them.
a and 26b are arranged. These sensors 26a, 26
A light emitting element such as a diode or a light receiving element is used as b. The sensors 26a and 26b first detect the leading edge passage of the banknote 1 that has passed the validator 10 side, while sending a detection signal that the trailing edge of the banknote 1 has passed to the CPU, and drive from the CPU after a certain period of time from this trailing edge passage detection. A switching signal for the direction of rotation of the source is sent.

Further, based on a detection signal indicating that the bill 1 has been inserted through the input port 11 of the validator 10, a start signal is sent from the CPU to a drive source including a motor 50, which will be described later, and the conveying device 20. In this case, the belt 23 starts rotating in the counterclockwise direction shown in FIG. 1 (hereinafter, this is referred to as normal rotation). A roller 27 is arranged behind the sensors 26a and 26b, and the roller 27 and the belt 2
It is a mechanism in which the banknote 1 is sandwiched between both sides and pulled in cooperation with the banknote 3. In addition, on the exit side of the second transport guide 22, that is, on the lower side of the drawing, there is provided a carrying portion 22b that is bent horizontally in the horizontal direction. This carrying portion 22b is the end point of the carrying, and the bill 1 sent from above in the drawing. This is the part that accepts.

As is apparent from FIGS. 2 and 3, a bill pushing device 30 is arranged below the carrying portion 22b of the second transport guide 22. This bill pushing device 3
0 is the banknote 1 received by the carrier 22b,
That is, the stacker 40 includes a pair of left and right rod members 31a and 31b that are pushed toward the box 41. The two rod members 31a and 31b are vertically fixed to the upper surface of the carrier 32, and the carrier 32 slides toward the stacker 40 so that the carrier 32 can move forward and backward. As shown in FIG. 4, the above-described second transport guide 22 includes two members 22 separated on the left and right sides.
It is composed of a and 22b, and the size of both sides is set to be substantially the same as the width of the bill 1. The carrier 32 can pass through the center gap between the left and right second transport guides 22 a and 22 b, and the two rod members 3 are moved forward by the carrier 32.
The central portion of the banknote 1 is forwardly stacked by the front stacker 40
It is a mechanism to push toward.

As shown in FIGS. 3 and 4, the carrier 32
Wheels 33a and 33b are provided in front of and behind the
3a and 33b are engaged with long grooves 3 provided on both side plates of the case 2, and the long grooves 3 can run as running rails.
Further, a stopper piece 34 extending downward is fixed to the carrier 32, and the pulling wire 3 is looped to the stopper plate 34.
Both ends of 5 are locked. That is, the pulling wire 35 that constitutes the pulling device rotates together with the pulling pulleys 36A and 36B described below, and the carrier 32 moves forward or backward. Figure 2
As also shown, opening windows 32 and 32b are provided in the front and rear walls of the carrier 32, through which the pulling wire 35 is inserted. The pulling wire 35 is a pair of pulling pulleys 36.
It is wound between A and 36B, and a tension spring 37 is connected to apply a required tension to the entire pulling wire 35. Of the pulling pulleys 36A and 36B, the pulling wire 35 is wound around one of the pulleys 36A several times, and a rotational driving force is applied as the driving side pulley 36A. The carrier 32 moves in the forward direction via the pulling wire 35 by the rotation of the drive pulley 36A. Further, the drive-side pulley 36A has a built-in one-way clutch mechanism, and the one-way clutch mechanism acts to rotate the rotation output from the drive source forward (counterclockwise in FIG. 3).
It is adapted to receive and rotate only to advance the carrier 32 to the left in the drawing. Therefore, when the rotation output of the drive source is reverse rotation (clockwise direction in FIG. 3), the drive pulley 36A idles even when receiving the reverse rotation output.

Further, as shown in FIG. 3, one end of each of a pair of left and right return springs (returning means) 39 is locked to the carrier 32. This return spring 39
Urges the carrier 32 to retract and return to the original position. Therefore, when the drive side pulley 36A idles to release the forward force when receiving the forward rotation output of the drive source, the carrier 32 is configured to be returned to the return position by the return spring 39.

Here, as a drive source, as shown in FIG. 2, a motor 50 and a reduction gear device 51 are provided, and a required (decelerated) rotation is driven (toothed) pulley 53 on an output shaft 52.
Output to. The rotation of the drive (toothed) pulley 53 is caused by the transport pulleys 24A, 24B of the transport device 20 described above, and the one drive side pulley 24A and the bill pushing device 3
0 is synchronously transmitted to the drive side pulleys 36A. That is, the shafts 24a, 36a of the drive side pulleys 24A, 36A
Driven (toothed) pulleys 54 and 55 are provided on the upper side, and an endless toothed belt 56 is wound around the drive gear 53 and the driven (toothed) pulleys 54 and 55 to drive (toothed). ) The rotation of the pulley 53 is driven by two driven (toothed) pulleys 5.
This is a structure in which the power is simultaneously transmitted to the drive side pulleys 24A and 36A via 4 and 55.

As described above, the drive side pulley 3 for towing
6A has a built-in one-way clutch mechanism,
When the rotation output of 0 is forward rotation (clockwise direction in FIG. 2), the transport drive pulley 24A rotates forward in the transport direction via the toothed belt 56, but the towing drive pulley 36A runs idle. It is supposed to do. When the motor 50 rotates in the reverse direction,
Upon receipt of the rotation output, the drive side pulley 36A for pulling the shaft 36
The carrier 32 is rotated via a to rotate the pulling wire 35 to advance the carrier 32. Drive side pulley 2
The drive side pulley 24A can idle on the shaft 24a by abutting the stop pin 25a provided on the shaft 24a of 4A with the stop pin 25a protruding from the drive side pulley 24A.

Next, the stacker 40 has a box 41 for accommodating bills, and the spring member 4 is provided near the bottom of the box 41.
A movable plate 42 is provided with 3 as a seat. Further, on the front side of the box body 41, a stopper side wall 44a bent from both sides,
The two rod members 31a and 31b described above pass through the space between the left and right stop side walls 44a and 44b and can enter and exit the box body 41. Therefore, the rod member 31
The banknote 1 stored in the box 41 by a and 31b is
After the pushing is released, the left and right stop side walls 44 on the front side
It is devised so as not to come out of the box body 41 again by hitting a and 44b. Locking pins 45a and 45b are projected and fixed to both outer walls of the box 41, and the locking pins 45a and 45b are engaged with guide grooves 4 and 4 formed by cutting both side plates of the case 2. It is supposed to meet. That is, by moving the box body 41 in the guide grooves 4 and 4 via the locking pins 45a and 45b, the entire stacker 40 can be attached to and detached from the case 2.

Optical sensors 61 and 62 for detecting the moving position of the carrier 32 are arranged in the box 41. One of the sensors 61 is a stack sensor for detecting the carrier 32 that pushes in and passes the banknote 1,
The other sensor 62 acts as a home sensor for detecting whether the carrier 32 is in the return position. The fact that the detection by the home sensor 62 is not allowed means that the carrier 32 does not advance further and does not pass due to the full state of the banknote 1 inside the box 41.
A signal indicating that the full state is detected, for example, a full notification device gives an alarm.

Next, the operation mode and operation of the embodiment apparatus having the above-mentioned configuration will be described. When the bill 1 is inserted into the validator 10, it is checked by the built-in CPU based on the detection data such as the amount of transmitted light 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 if the level is out of the level, the inserted bill 1 is not regarded as a true bill, and the bill is placed on the insertion shooter side. return.
Defective banknotes partially missing are also returned.

When the insertion of the bill 1 is detected, first, the home sensor 62 detects whether or not the carrier 32 of the bill pushing device 30 has returned to the original position. If the carrier 32 is located midway from the original position,
Since it is impossible to store the bill 1 in the box 41 by pushing the bill 1 thereafter, it is necessary to return the carrier 32 to the original position. Actuation signal from CPU is drive source motor 5
It is sent toward 0, and the motor 50 is started in the forward rotation direction. The forward rotation of the motor 50 causes the belt 23 of the transport device 20 to start rotating counterclockwise in FIG. At this time, in the banknote pushing device 30, the drive-side pulley 36A idles even if the motor 50 receives a positive rotation output, and if the carrier 32 is in the midway position, the return spring 39 pulls it back to the original position and returns. .

On the other hand, since the belt 23 of the conveying device 20 is rotating in the conveying direction by the forward rotation of the motor 50, the leading edge of the bill 1 which has passed the validator 10 is the sensor 26 first.
a and 26b are detected, and when the trailing edge of the bill 1 is detected, this detection signal is sent to the CPU, and after a certain period of time, the CPU sends a switching signal to the motor 50 to reverse the initial forward rotation. It is sent to switch to rotation. If it is determined that the trailing edge of the banknote 1 remains being detected, the banknote 1 is jammed and processed.

After that, the front end of the bill 1 is transferred to the second conveyor belt 2
The paper money 1 hits the carrying portion 22b, which is the end point of conveyance, and the banknote 1 faces the front of the stacker 40 in a standing posture. Almost in synchronism with this, a switching signal from the CPU based on the detection of a fixed time after passing the rear end of the bill 1 causes the motor 50 to switch to the driving in the reverse rotation direction, and the drive side pulley 36A of the bill pushing device 30. It rotates by receiving reverse rotation output. The rotation of the drive pulley 36A causes the carrier 32 to start to move forward via the pulling wire 35, and the carrier portion 2 of the second conveyor belt 22.
The banknote 1 having reached 2b is pushed out toward the box body 41 of the stacker 40.

As the carrier 32 moves forward, the left and right rod members 31a, 31b move forward, and the banknote 1 held by the carrying portion 22b is pushed into the box body 41 by the two rod members 31a, 31b. The carrier 32 advances as it is, and the stack sensor 61 detects the carrier 32. A signal is sent from the CPU to the motor 50 based on this detection signal, and the reverse rotation of the motor 50 is stopped. The carrier 32 that has not received the moving force via the pulling wire 35 due to the stop of the motor 50 is pulled back to the original returning position by the urging force of the return spring 39. Hereinafter, such an operation is repeated. When a large number of banknotes 1 are stacked in the box 41 and become full, the passage of the carrier 32 by the stack sensor 61 is not detected. Therefore, a full alarm or the like is detected to indicate that the box 41 has been removed. To do. The box 41 is tilted with respect to the case 2 as shown in FIG.
Alternatively, remove it completely and take out a full bill.

[0022]

As described above, in the bill handling apparatus according to the present invention, the conveying device and the bill pushing device share a single drive source, and the rotation output from this shared drive source is shared by both devices. Although they are given in synchronization, they can be switched between forward rotation and reverse rotation by the action of a one-way clutch mechanism provided in the bill pushing device. That is, since it is not necessary to separately provide a drive source separately as in the conventional case, the number of parts is greatly reduced and the entire apparatus becomes compact.
