Description

  The present invention relates to a bill storage device that is applied to an automatic vending machine, a currency exchange machine, etc., and transports a bill inserted from a bill insertion slot and stores it in a bill storage unit.

  DESCRIPTION OF RELATED ART Conventionally, the banknote accommodating apparatus (bill recognition apparatus) described in patent document 1 is known. The bill storage device determines whether the bill inserted from the bill insertion slot is true or false, transports the bill determined to be correct, and stores the bill in the bill storage portion. Thus, the bill storage device that transports the bill inserted from the bill insertion slot and stores it in the bill storage unit transports the bill inserted into the bill insertion slot into the inside of the apparatus main body along the transport path. A conveyance unit (bill conveyance mechanism), a pressing unit (a bill pushing mechanism) that pushes the conveyed bill into a bill storage box (a bill storage unit) to load and store, one motor capable of rotating in forward and reverse directions, and the motor Combined, both forward rotation and reverse rotation of the motor are transmitted to the bill conveyance portion (bill conveyance mechanism), and only the reverse rotation of the forward rotation and reverse rotation of the motor is, for example, the pressing means (bill Power transmission means (drive mechanism) for transmitting to the pushing mechanism).

  In such a bill storage device (bill recognition device), when the motor rotates forward, the pressing means does not operate, only the bill conveyance section operates, and the bill inserted into the bill insertion slot is processed by the bill conveyance section The motor is switched to reverse rotation in a state of being conveyed inside the main body and taken out of the conveyance path. Then, the bill which has left the conveyance path is pushed into the bill storage box by the pressing means operated by the reverse rotation of the motor. When the motor rotates in the reverse direction, the bill conveyance section carries out an operation of conveying the bill in the reverse direction toward the bill insertion slot, but since the bill is out of the conveyance path, it is not conveyed in the reverse direction. As described above, the sheet is pushed into the bill storage box by the pressing means, and is loaded and stored in the bill storage box.

  According to such a bill discriminating apparatus (bill accommodating apparatus), it is not necessary to provide separate power sources (motors) for the bill conveying portion and the pressing means, and a common driving source is provided for them. Since it is only necessary, cost reduction and downsizing of the device can be achieved.

Japanese Patent Application Laid-Open No. 6-150106

  However, in the above-described conventional bill storage device (bill recognition device), when the pressing means (bill pushing mechanism) is operated to load and store the bills in the bill storage box, the bill transport portion Are transported in the reverse direction (direction toward the bill insertion slot). For this reason, the bill which is going to be pushed into the bill storage box is conveyed in the reverse direction by the bending of the bill, etc., and the bill can not be reliably stored in the bill storage box (bill storage portion) there is a possibility.

  This invention is made in view of such a situation, and provides the banknote storage apparatus which can accommodate a banknote in a banknote accommodating part reliably.

  The bill storage device according to the present invention stores, in a bill storage portion, a bill transport mechanism for transporting a bill, which is input from a bill insertion port, along a transport path, and a bill whose rear end portion has passed the outlet position of the transport path. And a power source which is commonly provided to both the bill conveying mechanism and the bill pushing mechanism and is capable of forward movement and reverse movement, and is coupled to the power source And, when the power source operates in the forward direction, the bill transport mechanism is positively driven to transport the bill in the forward direction from the bill insertion slot to the outlet position without operating the bill pushing mechanism. The bill pushing mechanism performs the pushing operation while the bill conveying mechanism is reversely driven to convey the bill in the reverse direction from the outlet position toward the bill insertion slot when the power source operates in the reverse direction. A bill storage device having a drive mechanism, wherein, when the power source operates in the reverse direction, the outlet of the bill whose rear end portion has passed the outlet position by reverse driving of the bill transport mechanism It becomes a structure which has a bill return prevention mechanism which blocks return to a position.

  With such a configuration, when the power source is operated in the forward direction, the bill inserted from the bill insertion slot is transported along the transport path by the bill transport mechanism that is positively driven. At this time, the bill pushing mechanism does not operate. When the power source is operated in the reverse direction after the rear end of the bill conveyed along the conveyance path passes the exit position of the conveyance path, the bill exceeding the exit position of the conveyance path is the pushing operation of the bill pushing mechanism Is stored in the bill storage unit. At this time, although the bill conveyance mechanism is reversely driven, even if a bill which once exceeds the outlet position of the conveyance path is going to return to the outlet position by the bill conveyance mechanism reversely driven, the bill return blocking mechanism It is blocked to return.

  In the bill storage device according to the present invention, the bill return prevention mechanism is configured to move the bill transported by the bill transport mechanism, which is positively driven based on the forward movement of the power source, when the bill passes the outlet position. A configuration is provided that has a stopper mechanism that moves to a stopper position that prevents the return of the bill to the outlet position after the rear end of the bill passes the outlet position in the retracted position that does not prevent movement. it can.

  With such a configuration, when the power source operates in the forward direction, the bill return prevention mechanism is in the retracted position. In this state, the bill transported by the bill transport mechanism, which is positively driven based on the forward movement of the power source, passes the outlet position of the transport path without being blocked by the bill return prevention mechanism. After the rear end of the bill has passed the outlet position, the bill return blocking mechanism is at the stopper position. In this state, even if the bill is returned to the outlet position by the bill transport mechanism reversely driven based on the reverse operation of the power source, the bill is returned to the exit position by the bill return blocking mechanism at the stopper position. Is blocked.

  In the bill storage device according to the present invention, the stopper mechanism pivots between the retracted position which does not disturb the movement of the bill and the stopper position which blocks the return of the bill to the outlet position; And a biasing mechanism that applies a biasing force to the lever member so that the lever member is maintained at the stopper position, and the bill transported by the bill transport mechanism that is positively driven is transported before it reaches the outlet position. Moves the lever member located at the stopper position to the retracted position against the biasing force of the biasing mechanism and the lever after the rear end of the banknote passes the outlet position The member may be configured to return to the stopper position by the biasing force of the biasing mechanism.

  With such a configuration, when the power source operates in the forward direction, the bill transported by the bill transport mechanism that is positively driven is subjected to the biasing force of the biasing mechanism by the lever member located at the stopper position before reaching the outlet position. Move against the retraction position. Then, the bill is further transported by the bill transport mechanism that is positively driven, and after the rear end of the bill passes the outlet position, the lever member swings by the biasing force of the biasing mechanism to return to the stopper position. In this state, even if the bill is returned to the outlet position by the bill transport mechanism reversely driven based on the reverse operation of the power source, the bill is prevented from returning to the outlet position by the lever member at the stopper position. Be done.

  In the bill storage device according to the present invention, a detection signal of a first state is output when the lever member is in the retracted position, and a different state from the first state when the lever member is in the stopper position It can be set as the composition which has a detector which outputs the detection signal of two states.

  According to such a configuration, when the power source operates in the forward direction, the bill transported by the bill transport mechanism that is positively driven is attached to the lever member located at the stopper position before reaching the outlet position. Move to the retracted position against the force. Then, the detection signal from the detector changes from the second state to the first state. Further, the bill is further transported by the bill transport mechanism driven positively, and after the rear end portion of the bill passes the outlet position, the lever member swings by the biasing force of the biasing mechanism to return to the stopper position. Then, the detection signal from the detector changes from the first state to the second state. The fact that the detection signal from the detector changes from the first state and is in the second state indicates that the rear end of the bill has passed the outlet position. Therefore, the lever member of the stopper mechanism as the bill return prevention mechanism can be used as an outlet detector for detecting that the rear end of the bill has passed the outlet position.

  The bill storage device according to the present invention stores, in a bill storage portion, a bill transport mechanism for transporting a bill, which is input from a bill insertion port, along a transport path, and a bill whose rear end portion has passed the outlet position of the transport path. And a power source which is commonly provided to both the bill conveying mechanism and the bill pushing mechanism and is capable of forward movement and reverse movement, and is coupled to the power source And, when the power source operates in the forward direction, the bill transport mechanism is positively driven to transport the bill in the forward direction from the bill insertion slot to the outlet position without operating the bill pushing mechanism. When the power source reversely operates, the bill feeding mechanism is caused to perform the pushing operation while the bill conveying mechanism is reversely driven to convey the bill in the reverse direction from the outlet position toward the bill insertion slot. And a moving mechanism, and the outlet for detecting that the rear end portion of the bill transported by the bill transporting mechanism has passed through the outlet position when the power source operates in the forward direction. A detector; an operation switching control unit for switching the power source from the forward operation to the reverse operation when the outlet detector detects that the rear end of the bill has passed the outlet position; A bill return preventing mechanism for preventing a bill whose rear end portion has passed the outlet position from returning to the outlet position due to reverse driving of the bill transport mechanism when the power source operates in the reverse direction. It becomes.

  With such a configuration, when the power source is operated in the forward direction, the bill inserted from the bill insertion slot is transported along the transport path by the bill transport mechanism that is positively driven. At this time, the bill pushing mechanism does not operate. When the outlet detector detects that the rear end of the bill transported along the transport path has passed the outlet position of the transport path, the power source is switched from the forward operation to the reverse operation. Then, the bills exceeding the exit position of the transport path are accommodated in the bill accommodating portion by the pushing operation of the bill pushing mechanism by the reverse direction operation of the power source. At this time, the bill transport mechanism is reversely driven by the reverse operation of the power source, but the bill transport mechanism, which is driven reversely, returns the bill even if a bill which once exceeds the outlet position of the transport path is going to return to the outlet position. The blocking mechanism prevents the return to the exit position.

  In the bill conveyance device according to the present invention, a first operation starting from the start timing of the conveyance until the outlet position is passed without stopping the bill by the bill conveyance mechanism that is positively driven based on the forward movement of the power source. Forced operation to perform reverse operation for a second predetermined time and stop it when the outlet detector does not detect that the rear end of the bill has passed the outlet position even after the predetermined time has elapsed The forcible motion control unit for causing the power source to perform, and after the forcible operation of the power source is completed, when the exit detector detects that the rear end of the bill has passed the exit position And a reverse operation return control unit that causes the power source to operate in the reverse direction again.

  With such a configuration, when the bill conveying mechanism, which is positively driven based on the forward movement of the power source, starts to convey the bill until it passes the exit position without stopping the bill, the bill is usually at the exit position. It is conveyed to the point where the outlet detector detects that the rear end of the bill has passed the outlet position. However, even if the first predetermined time has elapsed from the start timing of the operation which is conveyed until the bill passes the exit position without stopping, the trailing edge of the bill passes the exit position by the exit detector. Is not detected, the power source is forced to perform a reverse operation for a second predetermined time and to stop it. By this forced operation, the bill pushing mechanism performs the pushing operation while the bill conveyance mechanism is reversely driven only for the second predetermined time. At this time, if it is in a situation that the bill can not be pushed into the bill accommodating portion by the pushing operation of the bill pushing mechanism though the rear end can not pass the outlet position for some reason, the bill will pass through the outlet position. There is a possibility that the not-yet-discarded bill can be passed through the outlet position by the pushing operation of the bill pushing mechanism. Then, if it is detected by the outlet detector that the rear end of the bill has passed the outlet position after the forcible operation is finished, the power source operates in the reverse direction again. By the reverse operation of the power source again, the bill transport mechanism is reversely driven, and the bill is housed in the bill housing portion by the pushing operation of the bill pushing mechanism.

  In the bill storage device according to the present invention, the outlet detector includes a lever member that pivots between a first position and a second position, and the lever so that the lever member is maintained at a second position. An urging mechanism for applying an urging force to the first member, and a detection signal of a first state when the lever member is in the first position, and the first state when the lever member is in the second position. And a detector main body for outputting a detection signal of a different second state, wherein the bill conveyed before the bill conveyed by the bill conveying mechanism that is positively driven reaches the outlet position is the second one. The lever member is moved to the first position against the biasing force of the biasing mechanism and is moved to the first position after the rear end of the bill passes the outlet position. Return to the second position by the biasing force of It can be configured.

  According to such a configuration, when the power source operates in the normal direction, the bill conveyed by the bill conveyance mechanism that is positively driven moves the lever member in the second position before the bill reaches the outlet position. Move to the first position against the biasing force. Then, the detection signal from the detector body changes from the second state to the first state. In addition, after the bill is further transported by the bill transport mechanism driven positively and the rear end of the bill passes the outlet position, the lever member swings by the biasing force of the biasing mechanism to move from the first position to the second position Return to Then, the detection signal from the detector body changes from the first state to the second state. The fact that the detection signal from the detector main body changes from the first state to be in the second state indicates that the rear end of the bill has passed the outlet position. That is, when the detection signal from the detector main body changes from the first state to the second state, it is possible to detect that the rear end of the bill has passed the outlet position.

  In the bill storage device according to the present invention, the first position is a retraction in which the lever member does not prevent the movement of the bill when the bill transported by the bill transport mechanism operating in the normal direction passes the outlet position. The second position is a position where the lever member prevents the return of the bill to the outlet position after the rear end of the bill passes the outlet position. be able to.

  With such a configuration, when the power source operates in the forward direction, the bill transported by the bill transport mechanism that is positively driven is subjected to the biasing force of the biasing mechanism by the lever member located at the stopper position before reaching the outlet position. Move against the retraction position. Then, the detection signal from the detector body changes from the second state to the first state. Then, the bill is further transported by the bill transport mechanism that is positively driven, and after the rear end of the bill passes the outlet position, the lever member swings by the biasing force of the biasing mechanism to return to the stopper position. Then, the detection signal from the detector body changes from the first state to the second state. Thus, it can be detected that the rear end of the bill has passed the outlet position, and the bill will be returned to the outlet position by the bill transport mechanism reversely driven based on the reverse operation of the power source. Also, the bill is prevented from returning to the outlet position by the lever member of the outlet detector in the stopper position.

  According to the bill storage device of the present invention, the power source is switched from the forward operation to the reverse operation, and the bill whose rear end portion once exceeds the exit position is reversely driven based on the reverse operation of the power source. Since the bill return blocking mechanism prevents the bill from returning to the outlet position even if it is returned to the direction of the outlet position by the bill transport mechanism, the bill having the rear end portion passing through the outlet position is reliably stored. Can be housed in the department.

  The bill storage device 100 has a device main body 110, an upper cover portion 120 and a rear cover portion 130. The upper cover portion 120 is provided so as to be openable and closable about a hinge at the upper rear end of the device body 110 (see FIG. 2), and the rear cover portion 130 is opened and closed about the hinge at the lower rear end of the device body 110. It is freely provided (see FIG. 3). A bill storage portion 40 for stacking and storing bills is formed in the apparatus main body 110, and a support plate 41 supported by a spring 42 extending upward from the bottom portion is provided in the bill storage portion 40. ing. Above the bill storage unit 40, a bill conveyance mechanism 10, a bill pushing mechanism 30, and a drive mechanism 51 mechanically coupled to a motor 50 and a motor 50 capable of forward rotation (forward operation) and reverse rotation (reverse operation). Is arranged. The motor 50 is a power source common to both the bill conveying mechanism 10 and the bill pushing mechanism 30.

  In the bill conveyance mechanism 10, a conveyance belt 13 is wound around a large diameter drive pulley 11 and a small diameter driven pulley 12, and the conveyance belt 13 circulates and moves by rotation of the drive pulley 11 (see FIG. 4, see FIG. 5). Two sets of drive pulleys 11, driven pulleys 12 and transport belts 13 are provided, and each set is provided along one of two opposing edge portions extending in the longitudinal direction of the apparatus main body 110. The upper portion of each conveyor belt 13 is exposed from the upper surface of the apparatus main body 110 as shown in FIG. 2 (in FIG. 2, only one conveyor belt 13 appears).

  In addition, since the two drive pulleys 11 rotate in synchronization, the two conveyance belts 13 circulate and move in the same manner. Therefore, hereinafter, the drive pulley 11, the driven pulley 12 and one set of the transport belts 13 which are wound around them and circulate and move will be described.

  The upper cover portion 120 is provided with the driven rollers 14 and 15 included in the bill transport mechanism 10 such that a part thereof protrudes from the bottom surface of the upper cover portion 120. The driven roller 14 is disposed so as to face the driven pulley 12 in the apparatus main body 110 with the conveying belt 13 interposed therebetween, and the driven roller 15 opposes the drive pulley 11 in the apparatus main body 110 with the conveying belt 13 interposed therebetween. It is arranged to be. Further, an outlet roller 16 (following roller) included in the bill transport mechanism 10 is provided in the rear cover portion 130 so that a part thereof protrudes from the inner side surface of the rear cover portion 130 (see FIG. 3). ing. The exit roller 16 is disposed to face a predetermined position (hereinafter, this position is referred to as an exit position Pout) immediately before the conveyance belt 13 is disengaged from the drive pulley 11 in the apparatus main body 110 (see FIG. See also 7A and 7B).

  A gap in which the bill BL can move between the bottom surface of the upper cover portion 120 and the upper surface of the device body 110 with the upper cover portion 120 closed with respect to the device body 110 (see FIGS. 1, 4 and 5) Is formed. By closing the upper cover portion 120 with respect to the apparatus main body 110, the gap portion is opened to the outside at the front end portion of the upper cover portion 120, and the gap portion extending from the bill insertion slot 101 is formed. A path from the winding portion to the drive pulley 11 to the outlet position Pout is formed as a transport path CV. At the front end portion of the device main body 110, an introduction tray 102 for guiding the bill BL to the bill insertion slot 101 is provided.

  In the bill conveyance mechanism 10 as described above, the bill BL fed from the bill insertion slot 101 through the introduction tray 102 is conveyed while being sandwiched between the conveyance belt 13 and the driven rollers 14 and 15 by the conveyance belt 13 that circulates. It is conveyed in the path CV toward the outlet position Pout. Then, the bill BL is conveyed until the rear end passes the outlet roller 16 at the outlet position Pout.

  The bill pushing mechanism 30 basically has the same configuration as that described in Patent Document 1. A guide member 31 having a U-shaped cross section is provided above the bill storage portion 40, and the bill pushing mechanism 30 passes the guide member 31 and can move up and down a push plate 32 and a push plate 32. It has a link mechanism 33 for moving up and down. The link mechanism 33 has basically the same configuration as the link device described in Patent Document 1, and vertically moves the push plate 32 engaged with the tips of the two frames by the movement of the two crossing frames. It has a structure.

  In the bill pushing mechanism 30 described above, as shown in FIG. 5, the push plate 32 is moved downward by the movement of the link mechanism 33 so that it is discharged from the conveyance path CV (outlet position Pout) and guided onto the guide member 31. The bill BL being pressed is pushed by the push plate 32, and the bill BL is pushed into the bill accommodating portion 40 in a state of being sandwiched between the push plate 32 and the support plate 41. Thereafter, the push plate 32 is moved upward by the reverse movement of the link mechanism 33, whereby the bills BL are accommodated in the bill accommodating portion 40 in a state of being stacked on the support plate 41.

  In the device main body 110, a stack sensor 25 is provided in association with the bill pushing mechanism 30. The stack sensor 25 outputs an OFF signal when the push plate 32 is in the initial position shown in FIG. 4, and the push plate 32 descends to push the bills stacked on the support plate 41 (see FIG. The ON signal is output to FIG.

  Note that a series of operations in which the push plate 32 is moved downward by the link mechanism 33 and thereafter the push plate 32 is lifted by the link mechanism 33 is referred to as a pushing operation for accommodating the bill BL in the bill accommodating portion 40. The bill pushing operation is different depending on the structure of the bill pushing mechanism 30, but it is not particularly limited as long as it is an operation for accommodating the bill BL in the bill accommodating portion 40.

  In the upper cover portion 120, an inlet sensor 21, an identification sensor 22, and a passage sensor 23 arranged along the transport path CV are provided. The inlet sensor 21 is provided at a position immediately after the bill insertion slot 101 of the transport path CV, and is configured of a lever member 21a and a detector 21b. A portion of the lever member 21a protrudes from the bottom surface of the upper cover portion 120 into the transport path CV (see FIGS. 2, 4 and 5). The lever member 21a is a bill BL transported in the transport path CV. Bounced up by In the state where the lever member 21a is flipped up, the detector 21b outputs a detection signal (ON) indicating that the bill BL has passed.

  The identification sensor 22 disposed at a position separated by a predetermined distance on the downstream side in the transport direction from the entrance sensor 21 includes a light emitting element 22 a provided on the upper cover portion 120 and a light receiving element 22 b provided on the apparatus main body 110. It is comprised (refer FIG. 2, FIG. 4 and FIG. 5). The light emitting element 22a and the light receiving element 22b are disposed to face each other across the transport path CV, the light emitting surface of the light emitting element 22a is exposed from the bottom surface of the upper cover portion 120, and the light receiving surface of the light receiving element 22b is the device body 110. Exposed from the top of the Then, based on the detection signal output from the light receiving element 22b that receives the light from the light emitting element 22a, it is possible to determine whether the bill BL is true or false.

  In practice, as shown in FIG. 2, a plurality of (for example, three) identification sensors 22 (a set of light emitting elements 22 a and light receiving elements 22 b) are arranged in a direction crossing the transport direction of the bills BL. Based on detection signals from the plurality of identification sensors 22 (light receiving elements 22b), it is possible to more accurately determine whether the inserted bill BL is true or false.

  The passage sensor 23 disposed at a position separated by a predetermined distance on the downstream side in the conveyance direction from the identification sensor 22 is configured by a lever member 23 a and a detector 23 b as in the case of the entrance sensor 21. A portion of the lever member 23a protrudes from the bottom of the upper cover portion 120 into the transport path CV (see FIGS. 2, 4 and 5), and this lever member 23a is a bill BL transported in the transport path CV. Bounced up by With the lever member 23a flipped up, the detector 23b outputs a detection signal (ON) indicating that the bill BL has passed.

  Although the drive mechanism 51 mechanically coupled to the motor 50 which is a power source common to both the bill conveying mechanism 10 and the bill pushing mechanism 30 described above is not illustrated in detail, Basically the same. That is, the drive mechanism 51 transmits the power of both the forward rotation and the reverse rotation of the motor 50 to the bill transport mechanism 10, and transmits the power of the forward rotation of the motor 50 to the bill pushing mechanism 30 by the one-way clutch. Instead, only the power of reverse rotation of the motor 50 is transmitted to the bill pushing mechanism 30. Therefore, the drive mechanism 51 transports the bill BL in the positive direction from the bill insertion slot 101 toward the outlet position Pout without operating the bill pushing mechanism 30 when the motor 50 rotates in the positive direction (positive direction operation). The drive pulley 11 of the transport belt 13 is rotated forward to move the transport belt 13 forwardly (forward drive of the bill transport mechanism 10). Further, the drive mechanism 51 reverses the drive pulley 11 of the transport belt 13 so as to transport the bill BL in the reverse direction from the outlet position Pout toward the bill insertion slot 101 when the motor 50 rotates in the reverse direction (reverse direction operation). While rotating the transport belt 13 in reverse circulation movement (reverse drive of the bill conveyance mechanism 10), the power of the motor 50 is transmitted to the bill pushing mechanism 30, and the pushing operation described above to the bill pushing mechanism 30 (link mechanism 33) Reciprocate the push plate 32).

  An outlet sensor 24 (outlet detector) is provided in the rear cover portion 130 so as to be disposed in a predetermined positional relationship with the outlet position Pout of the transport path CV. In the outlet sensor 24, when the motor 50 rotates forward, the rear end portion of the banknote BL transported in the forward direction by the banknote transport mechanism 10 (transport belt 13) passes the outlet position Pout (outlet roller 16). It is used to detect (the bill BL has left the transport path CV). The outlet sensor 24 includes a lever member 24a, a torsion spring 24b (biasing mechanism), and a detector main body 24c, as shown in FIGS. 7A and 7B described later, together with FIGS. 4 and 5. The lever member 24a prevents the return position (outward position Pout) of the bill BL that has passed through the exit position Pout and the retracted position (first position: see FIG. 7A) that does not prevent the passage of the exit position Pout of the transported bill BL. It can be pivoted about a predetermined axis with a stopper position (second position: see FIG. 7B). The torsion spring 24b (biasing mechanism) is mounted on the swing shaft of the lever member 24a, and biasing force is applied to the lever member 24b so that the lever member 24a is maintained at the stopper position (second position: see FIG. 7B). It is giving.

  The lever member 24 a is a torsion spring 24 b of the torsion spring 24 b by the bill BL being transported before the bill BL transported in the forward direction by the transport belt 13 that circulates forwardly based on the forward rotation of the motor 50 reaches the outlet position Pout. It is pivoted from the stopper position (see FIG. 7B) to the retracted position (see FIG. 7A) against the biasing force. Then, after the rear end of the bill BL passes through the outlet position Pout, the lever member 24a and the bill BL being conveyed are released, and the lever member 24a is retracted by the biasing force of the torsion spring 24b (FIG. 7A). Return to the stopper position (see FIG. 7B) from the reference).

  When the lever member 24a is in the retracted position (first position: see FIG. 7A), the detector body 24c outputs a detection signal in the first state (ON) by the influence of the lever member 24a. When the lever member 24a is in the stopper position (second position: see FIG. 7B), the detection signal of the second state (OFF) different from the first state is outputted without being influenced by the lever member 24a. Do. Whether the rear end of the bill BL transported in the forward direction has passed the outlet position Pout (outlet roller 16) based on the state (first state or second state) of the detection signal from the detector main body 24c It can be determined whether or not.

  In the lever member 24a of the outlet sensor 24 and the torsion spring 24b (biasing mechanism), the bill BL whose rear end portion has passed the outlet position Pout by the forward rotation of the motor 50 is reversely circulated based on the reverse rotation of the motor 50 It also functions as a bill return mechanism (stopper mechanism) that prevents the conveyance belt 13 (bill conveyance mechanism 10) from returning to the outlet position Pout.

  In the bill storage device 100 described above, the bill BL is stored in the bill storage portion 40 as follows.

  When the bill BL is fed from the bill insertion slot 101 and the bill BL is detected by the inlet sensor 21 (output of an ON signal) as shown in FIG. 6A, the motor 50 starts to rotate forward. The drive pulley 11 of the banknote transport mechanism 10 is positively rotated by the drive mechanism 51 coupled to the motor 50 rotating positively, whereby the transport belt 13 is positively circulated. The bill BL inserted into the bill insertion slot 101 is conveyed in the forward direction toward the exit position Pout by the transport belt 13 that moves forward in a forward circulation. At this time, motive power of positive rotation of the motor 50 is not transmitted to the bill pushing mechanism 30 by the one-way clutch included in the drive mechanism 51, and the bill pushing mechanism 30 does not operate.

  The bills BL transported by the transport belt 13 moving forward and forward pass through the position of the identification sensor 22 as shown in FIGS. 6B, 6C and 6D. Under the present circumstances, the true / false of bill BL is judged based on the detection signal from discernment sensor 22 (light sensing element 22b), and bill BL judged to be a regular thing is further conveyed by conveyance belt 13 which carries out normal circulation movement. It is transported toward the exit position Pout. Then, as shown in FIGS. 6D and 6E, when the bill BL passes through the position of the passage sensor 23, confirmation of the conveyed bill BL is further performed based on a detection signal from the passage sensor 23, The bill BL is transported.

  In the process of approaching the outlet position Pout (outlet roller 16), the transported bill BL causes the lever member 24a of the outlet sensor 24 to gradually swing from the stopper position against the biasing force of the torsion spring 24b. Before reaching, in the retracted position. Then, as shown in FIG. 6E and enlarged in FIG. 7A, the transported bill BL passes through the outlet position Pout (outlet roller 16) while keeping the lever member 24a at the retracted position.

  In the state where the lever member 24a is in the retracted position (see FIG. 7A) by the passage of the bill BL transported as described above through the outlet position Pout, the detector main body 24c is turned ON by the influence of the lever member 24a. (The detection signal of the first state) is output. By the ON signal from the detector main body 24c, it can be confirmed that the bill BL has passed the outlet position Pout.

  Furthermore, when the bill BL is conveyed and the rear end of the bill BL passes the outlet position Pout as shown in FIG. 6F and as enlarged in FIG. 7B, the lever member 24a and the bill BL are disengaged The biasing force of the torsion spring 24b causes the lever member 24a in the retracted position to pivot back to the stopper position. As described above, when the lever member 24a returns from the retracted position (see FIG. 7A) to the stopper position (see FIG. 7B), the detector main body 24c is not affected by the lever member 24a, and the OFF signal (second state detection signal) Output). It can be confirmed by the OFF signal from the detector main body 24c that the rear end of the bill BL has passed the outlet position Pout (outlet roller 16).

  When the detection signal of the detector main body 24c of the outlet sensor 24 changes from ON to OFF, it is confirmed that the rear end of the bill BL has passed the outlet position Pout (outlet roller 16), the motor 50 is reversed. It is switched to rotation. The motive power of the motor 50 is transmitted to both the bill transport mechanism 10 and the bill pushing mechanism 30 by the drive mechanism 51 coupled to the motor 50 rotating in the reverse direction. Thereby, the drive pulley 11 of the bill transport mechanism 10 is reversely rotated to cause the transport belt 13 to perform reverse circulation movement, and the bill pushing mechanism 30 performs a pushing operation. By the pushing operation of the bill pushing mechanism 30, the bill BL (see FIG. 7B) which passes through the outlet position Pout and is guided by the guide member 31 is housed in the bill housing portion 40 so as to be stacked on the support plate 41. Ru.

  By the way, as described above, when the motor 50 is reversely rotated to operate the bill pushing mechanism 30 after the rear end of the bill BL has passed the outlet position Pout (outlet roller 16), the transport belt 13 is reversely circulated. Moving. The paper money BL, the rear end of which has passed through the outlet position Pout, may be returned to the outlet position Pout by the transport belt 13 moving in reverse circulation. As described above, even if the bill BL is to be returned to the outlet position Pout, the lever member 24a of the outlet sensor 24 functioning as a bill return blocking mechanism (stopper mechanism) is at the stopper position. The part abuts on the lever member 24a (see FIG. 7B), and the bill BL is prevented from returning to the outlet position Pout and being caught in the outlet roller 16. Therefore, the bill BL can be reliably accommodated in the bill accommodating portion 40 by the pushing operation of the bill pushing mechanism 30 without the occurrence of the bill jam.

  In the control system of the bill storage device 100 described above, as shown in FIG. 8, the processing unit 60 detects bills on the basis of detection signals from the input sensor 21, the identification sensor 22, the passage sensor 23, the outlet sensor 24 and the stack sensor 25. Control of forward and reverse rotation and stop of the motor 50 serving as a power source common to both the transport mechanism 10 and the bill pushing mechanism 30 is performed. The processing unit 60 causes the bill storage device 100 to store the bill BL inserted into the bill insertion slot 101 in the bill storage unit 40 (see FIGS. 5A to 6F, and FIGS. 7A and 7B). Processing is performed according to the procedure shown in FIGS. 9, 10A and 10B.

  Before the processing according to the procedure shown in FIGS. 9, 10A and 10B, the processing unit 60 performs processing to determine whether the bill BL inserted into the bill insertion slot 101 is true or false.

  First, when the detection signal (ON) of the bill BL is input from the input sensor 21 (see FIG. 6A), the processing unit 60 rotates the motor 50 in the forward direction. As a result, the bill BL inserted into the bill insertion slot 101 is conveyed toward the outlet position Pout (in the forward direction) by the conveyance belt 13 that circulates forward. And while bill BL passes the position of discernment sensor 22 (refer to Drawing 6B and Drawing 6C), processing unit 60 takes in the detection signal from discernment sensor 22 (light sensing element 22b). Then, after the rear end of the bill BL passes the position of the identification sensor 22 (see FIG. 6D), the processing unit 60 temporarily stops the motor 50, and the bill BL is detected based on the detection signal (detection information) fetched. Determine whether the If it is determined that the bill BL is false, the processing unit 60 reversely rotates the motor 50 and discharges the bill BL from the bill insertion slot 101. At this time, the bill pushing mechanism 30 performs a pushing operation (empty operation) by reverse rotation of the motor 50 in a state where there is no bill BL remaining after passing the exit position Pout.

  If it is determined that the bill BL is legitimate, the processing unit 60 performs processing relating to loading control according to the procedure shown in FIG.

  In FIG. 9, the processing unit 60 sets the internal timer T to the first predetermined time α1 (S11), starts the internal timer T (S12), and causes the motor 50 to rotate forward (S13). The first predetermined time α1 is set to a time sufficient to pass the outlet position Pout without stopping the banknote BL, for example, about 3 seconds from this time (this position: see FIG. 6D). When the forward rotation of the motor 50 is resumed, the bill BL is conveyed toward the outlet position Pout while passing the position of the passage sensor 23 as described above. In the process, while confirming that the internal timer T set to α1 has not timed out (NO in S14), the processing unit 60 determines whether or not the detection signal from the passage sensor 23 is OFF. To do (S15).

  While the bill BL is passing the position of the passage sensor 23 (see FIG. 6D, FIG. 6E), the processing unit 60 performs the same process (S14, S15). When the detection signal from the passage sensor 23 is detected to be OFF when passing the position (YES in S15), the detection signal from the outlet sensor 24 (detector main body 24c) is turned OFF. It is determined whether or not (S16). In this case, as shown in FIG. 6E, since the leading end of the bill BL reaches the outlet position Pout before the trailing end of the bill BL passes the position of the passage sensor 23, the detection signal from the passage sensor 23 is OFF. After (YES at S15), the detection signal from the outlet sensor 24 is ON. For this reason, the processing unit 60 determines that the detection signal of the outlet sensor 24 is not OFF, that is, the banknote BL has not passed the outlet position Pout (NO in S16). Thereafter, in the processing unit 60, the internal timer T has not timed up (NO in S14), the detection signal from the passage sensor 23 is OFF (YES in S15), and the detection signal from the outlet sensor 24 is Repeatedly confirm that it is not OFF (NO in S16).

  In the process, the bill BL continues to be transported in the positive direction while passing the outlet position Pout. Then, when the rear end of the bill BL passes the outlet position Pout and the detection signal from the outlet sensor 24 is turned off (YES in S16), the processing unit 60 stops the motor 50 (S17). At this time, as shown in FIGS. 6F and 7B, the bill BL is ready to be accommodated in the bill accommodating portion 40 with the rear end portion passing the outlet position Pout.

  When the processing unit 60 stops the motor 50 (S17), the processing unit 60 performs processing relating to banknote stack control according to the procedure shown in FIGS. 10A and 10B.

  In FIG. 10A, the processing unit 60 sets the pressing flag to ON (S21), and reversely rotates the motor 50 (S22: operation switching control unit). Thereby, the bill pushing mechanism 30 starts the pushing operation as described above. Thereafter, after confirming that the detection signal from the outlet sensor 24 is not ON (NO in S23), the processing unit 60 confirms that the pressing flag is set ON (YES in S24). It is determined whether the detection signal from the sensor 25 is ON, that is, whether the push plate 32 of the pushing mechanism 30 is lowered to push the bill BL guided to the guide member 31 (S25) ). Thereafter, the processing unit 60 repeatedly performs the same confirmation (S24, S25). Then, when the push plate 32 of the bill pushing mechanism 30 descends to push the bill stacked in the support plate 41 and the detection signal from the stack sensor 25 is turned on (YES in S25), the processing unit 60 Then, the pressing flag is rewritten to OFF (S26), and it is repeatedly confirmed that the pressing flag is OFF (NO in S24) and that the stack sensor 25 is not OFF (NO in S27). In this state, the push plate 32 of the bill pushing mechanism 30 is moving upward, and when the push plate 32 reaches the prescribed initial position (see FIG. 4), the detection signal from the stack sensor 25 is turned off. When the processing unit 60 confirms that the detection signal from the stack sensor 25 is turned off (YES in S27), the processing unit 60 stops the motor 50 (S28), and waits for the next bill BL to be inserted.

  As described above, the processing unit 60 performs processing related to loading control (see FIG. 9) and processing related to stacking control (FIG. 10A), so that the processing unit 60 is inserted into the bill insertion slot 101 and determined to be legitimate. The bill BL is stored in the bill storage unit 40.

  In the process of processing relating to acquisition control shown in FIG. 9, even if it is not confirmed that the detection signal from the passage sensor 23 is OFF even if the internal timer T times out (YES in S14), that is, the first If the detection signal of the passage sensor 23 is maintained in the ON state even after the predetermined time α1 (for example, 3 seconds) elapses (NO in S15, YES in S14, NO in S18), the processing unit 60 controls the motor 50 is stopped (S19), and a predetermined banknote jam processing is executed assuming that the banknote BL is jammed in the transport path CV (a banknote jam).

  In addition, in the process of processing relating to capture control shown in FIG. 9, when the internal timer T has timed up (YES in S14), the detection signal from the passage sensor 23 is in the OFF state, that is, the bill BL passes Although it has been confirmed that the position of the sensor 23 has been passed (YES in S15, YES in S18), the detection signal from the outlet sensor 24 is OFF, that is, the rear end of the bill BL passes through the outlet position Pout. When it can not be confirmed (NO in S16), the processing unit 60 stops the motor 50 (S17), and shifts to the processing related to the banknote stack control shown in FIG. 10A as in the normal state. In this case, since the detection signal from the outlet sensor 24 is ON, the bill BL is clogged while passing through the outlet position Pout. For example, the bill BL is caught on the lever member 24 a of the outlet sensor 24 It is assumed that.

  In FIG. 10A, the processing unit 60 turns on the pressing flag (S21) as described above, and reversely rotates the motor 50 (S22: forced operation control unit). Thereby, the conveyance belt 13 of the bill conveyance mechanism 10 starts reverse circulation movement, and the bill pushing mechanism 30 starts pushing operation. At this time, since the detection signal from the outlet sensor 24 is ON (YES in S23), the processing unit 60 shifts to the processing shown in FIG. 10B and rotates the motor 50 (reverse rotation) that has started reverse rotation. It is determined whether pulses generated in synchronization with the pulse number output from encoders mounted on the motor 50 have reached a specified number, for example (S29). The predetermined number corresponds to a time (second predetermined time) in which the bill pushing mechanism 30 is slightly operated in consideration of the pulse cycle. When the processing unit 60 determines that the number of pulses generated in synchronization with the rotation of the motor 50 has reached the specified number (YES in S29), the motor 50 is stopped (S30: forced operation control unit). Thereby, the pushing operation | movement of the banknote pushing mechanism 30 stops.

  After that, the processing unit 60 sets a predetermined time T2 (for example, 100 msec) in the internal timer T (S31), starts the timer T (S32), and determines whether the timer T times up. (S33). When a predetermined time α2 has elapsed since the motor 50 stopped and it is determined that the timer T has timed out (YES in S33), the processing unit 60 determines whether the detection signal from the outlet sensor 24 is ON. (S34). Here, if the detection signal from the outlet sensor 24 is not ON (if OFF) (NO in S34), the processing unit 60 assumes that the rear end of the bill BL has passed the outlet position Pout, as shown in FIG. 10A. Returning to the process shown, the motor 50 is reversely rotated again (S22: reverse operation return control unit). Thereafter, the processing unit 60 performs the same processing as the processing (S23 to S28) related to the banknote stack control at the normal time. As a result, the bill pushing mechanism 30 carries out the pushing operation, and the bill BL is accommodated in the bill accommodating portion 40.

  If the detection signal from the outlet sensor 24 maintains the ON state even if the motor 50 is slightly rotated reversely (YES in S34), for example, the outlet sensor 24 is abnormal or the bill BL is an outlet sensor The processing unit 60 performs predetermined abnormality processing, assuming that the lever member 24a of 24 is still caught.

  According to the processing (see FIG. 9) related to loading control by the processing unit 60 as described above and the processing (refer to FIGS. 10A and 10B) related to the bill stack control, the bill BL inserted into the bill insertion slot 101 is properly The operations of the bill transport mechanism 10 and the bill pushing mechanism 30 that use one motor 50 as a common drive source can be controlled so as to be able to be accommodated in the bill storage unit 40.

  Further, in particular, from the start timing of the operation of conveying the banknote BL to the exit position Pout without stopping it (for example, the start timing of the conveyance operation of the banknote BL resumed after recognition of the authenticity of the banknote BL) Even when the predetermined time α1 (for example, 3 seconds) has passed, the outlet sensor 24 is detecting that the bill BL is passing (ON), and the rear end of the bill BL passes the exit position Pout. When the event (OFF) is not detected, the banknote pushing mechanism 30 is caused to perform the pushing operation for a short time. For this reason, it can be forcedly eliminated that the bill BL is caught at the outlet position Pout, etc., and the operation rate of the bill storage device 100 can be improved.

  Furthermore, the outlet sensor 24 prevents the return of the bill BL whose rear end portion has passed the outlet position Pout to the outlet position Pout due to the reverse circulation movement of the transport belt 13 when the motor 50 is reversely rotated. Since it also has the function of a blocking mechanism (stopper mechanism), the number of parts of the device can be reduced.

  For example, a bill return prevention mechanism (stopper mechanism) composed of the lever member 24a of the outlet sensor 24 and the torsion spring 24b may be provided separately from the outlet sensor 24. Also, a plurality of bill return prevention mechanisms (stopper mechanisms) can be provided.

  The outlet sensor 24 is not limited to the structure including the lever member 24a, the torsion spring 24b, and the detector main body 24c, and may detect another structure, for example, the bill BL optically passing through the outlet position Pout. Good.

  The present invention is not limited to the above-described embodiment and the modification thereof. Various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

  The bill storage device according to the present invention has an effect that the bill can be reliably stored in the bill storage portion, and is applied to an automatic vending machine, a currency exchange machine, etc., and transports the bill inserted from the bill insertion slot. It is useful as a bill storage device that is stored in a bill storage unit.
