  The casing 10 is placed on a cashier counter stand in the store. The housing 10 is juxtaposed with a coin change machine (not shown), and is arranged facing the cashier with a POS terminal as a host device placed on the change machine 1 and the coin change machine. The deposit port 11 accepts the deposited banknote in a posture in which the long side pair is horizontal. The long side means the side on the top and the ground side with respect to the person image of the banknote when the banknote is properly obtained.

  The depositing unit 12 has a chamber for storing banknotes deposited from the depositing port 11. The banknotes are separated one by one from the chamber, and the banknotes are fed out in a standing posture and sent to the conveying unit 16 side. The depositing unit 12 includes a guide that is continuous with the chamber and has an upper and lower slope, and a plurality of roller pairs provided in the guide. The depositing unit 12 slides and pulls out the lowest two or three banknotes out of one banknote or a bundle of banknotes on the guide slope by these roller pairs. Separate two or three bills one by one. After the depositing unit 12 is separated, the banknote in the standing posture is guided to the transport unit 16 toward the left side of the casing as shown in FIG.

  The withdrawal port 13 is an opening for discharging the banknote from the inside of the housing to the outside of the housing in a posture in which the pair of long sides is horizontal. The dispensing unit 14 discharges the banknotes that are vertically conveyed in a posture standing one by one from the left side of the housing by the transportation unit 16 from the dispensing port 13 to the outside of the housing. Longitudinal transport refers to transporting a pair of long sides of a banknote approximately horizontally, transporting one short side forward of the banknote transport direction and the other short side in a direction opposite to the banknote transport direction. The withdrawal unit 14 accepts and stacks the banknotes from the transport unit 16 one by one from one short side in a posture in which one long side is horizontal, and ascending and descending to move the withdrawal hopper 22 up and down. Mechanism.

  The storage unit 15 includes a 1,000-yen ticket storage unit 23, a 5,000-yen ticket storage unit 24, and a 10,000-yen ticket storage unit 25, each of which is a rectangular parallelepiped storage. The thousand-yen ticket storage unit 23 stands up the thousand-yen ticket, and stores the thousand-yen ticket in a state where the face of the ticket faces the front and the long side is parallel to the casing width direction. The thousand yen ticket storage unit 23 stores a plurality of thousand yen tickets aligned in the same direction. The thousand-yen ticket storage unit 23 is provided with a thin slit-like opening 26 in the vertical direction on one side surface of the thousand-yen ticket storage unit 23. The thousand yen coupon storage unit 23 takes in the bills branched and conveyed from the main conveyance path 32 by the movable conveyance path unit 27 described later. The structure of the 5,000-yen ticket storage unit 24 and the 10,000-yen ticket storage unit 25 is substantially the same as the structure of the thousand-yen ticket storage unit 23. The storage capacity of the thousand-yen ticket storage unit 23 may be larger than any of the storage capacity of the 10,000-yen ticket storage unit 25 and the storage capacity of the five thousand yen ticket storage unit 24.

  The transport unit 16 has a mechanism for holding the banknote and transporting it in the forward and reverse directions, and a transport space through which the banknote passes. The conveyance unit 16 includes a plurality of pairs of conveyance rollers 28 each having a vertical rotation axis, a plurality of pairs of guides 29 that respectively guide bills, and a motor that rotates one of the pair of conveyance rollers 28. Yes. The roller outer peripheral surfaces of the pair of transport rollers 28 form a nip. The nip refers to a gap between the outer peripheral surfaces of the conveying roller 28. These nip rows almost form a main transport path in plan view. The plurality of pairs of guides 29 are mainly provided between adjacent nips. The conveyance space is defined by a plurality of nips and guide surfaces of a plurality of guides 29 on both sides of these nips. In this conveyance space, the conveyance unit 16 conveys the banknotes in a standing posture in which the pair of short sides faces front and rear in the conveyance direction.

  Further, the change machine 1 is provided with three movable conveyance path portions 27 that operate as branch conveyance paths of the main conveyance path 32 on the conveyance section 16. One movable conveyance path unit 27 moves the movable conveyance path unit 27 away from the conveyance unit 16 and is isolated from the main conveyance path 32, and the movable conveyance path unit 27 itself is moved to the conveyance unit 16 side to move to the main unit. The second position to be continuous with the transport path 32 is taken. In the second position, the movable conveyance path unit 27 draws the banknote into any of the storage units 15. Each movable conveyance path unit 27 can individually switch connection and disconnection of the branch path by a command from the control unit 20.

  Furthermore, the change machine 1 is provided with identification units 30 and 31 for identifying denominations on the transport unit 16. The identification unit 30 operates when the deposited banknote is stored in the storage unit 15 and when the banknote is withdrawn from the storage unit 15. The identification unit 30 is configured by combining one or more of various sensors such as a light shielding sensor, a reflective optical sensor, a transmissive optical sensor, a magnetic sensor, or a material sensor.

  The light shielding sensor measures the dimension in the long side direction and the dimension in the short side direction of the standing banknote. The reflective optical sensor detects the amount of reflected light by irradiating the bill with light. The transmissive optical sensor detects the amount of transmitted light by irradiating the bill with light. A magnetic sensor detects the magnetism adhering to a banknote. The material sensor measures the electrical resistance value of the bill surface. The identification unit 30 stores a threshold value of a predetermined physical quantity, and compares the measured physical quantity such as size, light, magnetism, and resistance value with a corresponding threshold value. The identification unit 30 determines whether the denomination information is acquired in order to receive the deposited banknote or the denomination of the banknote being withdrawn from the storage unit 15 is equal to the denomination included in the payment instruction. . The identification unit 31 is the same as the identification unit 30.

  The optical sensor 17 is a light shielding sensor provided in the upper part of the conveyance space. The optical sensor 17 includes a light transmitter 17 a that irradiates a light beam having straightness, a light receiver 17 b that receives the light beam, and a circuit unit that electrically sends on / off outputs of the light receiver 17 b to the control unit 20. And have. A light beam refers to a beam of visible light, near infrared light, or infrared light. On means that the light receiver 17b receives the light beam. OFF means that the light receiver 17b does not receive the light beam. The height position in the change machine 1 through which the light beam between the light transmitter 17a and the light receiver 17b passes is arranged to be equal to or slightly lower than the height position of the upper long side of the standing banknote. . The optical sensor 17 detects the presence of the front and rear corners of the upper long side of the banknote in a standing position passing through the conveyance space. The corner refers to a corner where the long side and the short side of the bill meet and a bill face area around the corner.

  The optical sensor 18 includes a light transmitter 18 a, a light receiver 18 b, and a circuit unit, and has the same structure as that of the optical sensor 17. On or off means that the light receiver 18b receives or does not receive the light beam. The height position of the light beam between the light transmitter 18a and the light receiver 18b is equal to or slightly higher than the height position of the lower long side of the standing banknote. The optical sensor 18 detects the presence of the front and rear corners of the lower long side of the bill being conveyed. The height position of the light beam stretched by the optical sensor 17 and the height position of the light beam stretched by the optical sensor 18 are determined in advance. These height position values can be changed in order to increase the detection accuracy of corner breakage or to the extent that erroneous detection is avoided. The value is determined in advance through experiments, simulations, and tests.

  The corner breakage detection unit 19 detects the on / off detection signal output from the optical sensor 17 for the upper long side, and the front end, rear end, or front / rear of the upper long side of the bill depending on the on / off change of the detection signal. The position of both ends and the corner break of the bill at each position are detected.

  The pair of optical sensors 17 and 18 outputs different detection values of off (shielding) or on (light reception) according to the presence or absence of corners, and the corner break detection unit 19 detects on / off output change by the optical sensor 17. It is determined whether the timing and the timing of the on / off output change by the optical sensor 18 are simultaneous, and the corner break and the position of the corner break are detected. For example, the corner break detection unit 19 simultaneously detects one of the front end and the rear end of the lower long side of the bill and the corner break of the bill at the front end or the rear end. The corner break detection unit 19 similarly detects the upper long side. A CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) are used for the corner break detection unit 19.

  The control unit 20 rejects the banknote from the deposit port 11 or the withdrawal port 13 when there is a fold of the bill by the corner fold detection unit 19. The control unit 20 has a denomination counter for storing the number of banknotes stored for each denomination. The control unit 20 can exchange control signals and information data with the POS terminal. The control unit 20 generates information for displaying the position of the corner break. The control unit 20 uses a CPU, ROM, and RAM. The display device 21 is, for example, a liquid crystal display, and displays any one of the four corners of a square pattern representing a banknote when the occurrence of the banknote fold is detected.

  The ROM stores an application program (computer program) for operating the computer device as the change machine 1. This application program includes a function for counting the number of stored banknotes of the received banknotes in the computer device by the identification units 30 and 31, a function for transporting the banknotes in the forward and reverse directions by the transport unit 16, and an optical sensor 17. , 18, the function of detecting the corners of the four corners of the bill conveyed in the bill conveyance direction is executed. This application program allows a computer device to change the detection output of the optical sensors 17 and 18, the size between the pair of short sides of the banknote, and the conveyance speed, and the position of any of the corners of the four corners and the banknote at that position. A function of detecting corner breaks and a function of generating information for displaying a position are executed. A conveyance speed means the speed of the banknote at the time of the optical sensors 17 and 18 being conveyed and passing.

  The deposit / withdrawal operation of the change machine 1 will be described with reference to FIGS. A method for detecting corner breakage will be described with reference to FIGS.

  FIG. 3 is a flowchart for explaining the deposit / withdrawal operation of the change machine 1. It is assumed that a thousand yen voucher having no corner break is deposited by cashier operation to the change machine 1 having the above-described configuration. In Act A1, when the depositing unit 12 detects that a piece of paper has been inserted into the depositing port 11, in Act A2, the conveying unit 16 starts conveying the piece of paper in the forward direction. In Act A3, the change machine 1 identifies and determines the piece of paper by the identification units 30 and 31. If the identification result is affirmative in Act A3, the YES route is passed. In Act A4, the change machine 1 writes denomination data of 1,000 yen to the memory, and increases the value of the 1000 yen counter. A positive result means that 1,000 yen is a genuine note.

  Subsequently, in Act A5, the change machine 1 determines whether or not the banknote is bent. The corner break detection unit 19 performs corner break detection. FIG. 4 is a diagram for explaining a method for determining whether or not a banknote has a broken corner. The figure shows an example in which a banknote being conveyed is viewed from the left side surface of the housing 10. The above described symbols represent the same elements. As shown in FIG. 4A, the corner break detection unit 19 drives the optical sensors 17 and 18 by energizing them before the front edge of the banknote arrives. The light transmitters 17a and 18a start to output a light beam. A light beam parallel to the casing width direction is generated above the conveyance space. A light beam parallel to the casing width direction is generated below the transport space.

  As shown in FIG. 4B, the banknote continues to block the two light beams that are vertically parallel until the banknote passes through between the optical sensors 17 and 18. During this time, the optical sensors 17 and 18 continue to output OFF. The length of time required to complete the passage is determined by the size of the long side of one bill and the transport speed of the bill. The change machine 1 determines in advance the start timing of the passage period and the drive start timing of the optical sensors 17 and 18. As an example, the corner break detection unit 19 may receive a timing signal from the transport unit 16 that can trigger a passage period. For example, a deposit detection signal can be used as the start trigger for the passage period.

  As shown in FIG. 4C, the bill passes between the optical sensors 17 and 18. If the optical sensors 17 and 18 are simultaneously turned from on to off within the bill passage period, and are continuously turned off after being turned off, the corner break detector 19 determines that the bill is a normal bill without corner break. To do. The corner break detection unit 19 detects that a bill without corner break has passed anywhere on the upper and lower long sides.

  If it is determined in Act A6 (FIG. 3) that there is no corner break, the change machine 1 passes the YES route and stores the banknote in the storage unit 15 in Act A7. For example, the change machine 1 conveys a thousand yen ticket to the front of the thousand yen ticket storage unit 23. The change machine 1 vertically conveys a thousand yen ticket with one short side of the thousand yen ticket facing the depth. When approaching the thousand yen ticket storage unit 23, the change machine 1 generates a branching path by the movable conveyance path unit 27, and sends the thousand yen ticket from the main conveyance path 32 to the opening 26. When the light-shielding sensor provided in the opening 26 detects passage of a bill, the change machine 1 increments the counter for the number of held thousand yen coupons by one. The change machine 1 returns the switching position of the movable conveyance path unit 27 to the original position, and cancels the generated branch path.

  On the other hand, as a case where the change machine 1 detects a corner break in Act A6, a bill having a corner break on the front upper side will be described. FIG. 5 is a diagram for explaining a method for determining whether or not a banknote has a corner break. The above described symbols represent the same elements.

  As shown to Fig.5 (a), a banknote has the corner fold 32 at the upper left in the figure (upper side with respect to a banknote conveyance direction). The corner break detection unit 19 starts driving the optical sensors 17 and 18 before the front edge of the banknote arrives. As shown in FIG. 5 (b), the front edge of the bill starts to pass through a vertical plane including upper and lower light beams. The vertical plane is a plane area including a light beam stretched up and down by the optical sensors 17 and 18. Since there is no obstruction due to the corner fold 32, the light receiver 17b of the optical sensor 17 outputs ON. On the lower side with respect to the banknote transport direction, there is no corner break and the light beam is shielded, so the light receiver 18b of the optical sensor 18 outputs OFF. When the bill is further conveyed, the corner break 32 passes through the light beam by the optical sensor 17.

  When the bill further advances, as shown in FIG. 5C, the upper and lower corners in front of the bill both block the light beam. Both the optical sensors 17 and 18 output OFF. When the trailing edge of the bill passes through the vertical plane, both the optical sensors 17 and 18 start to output ON. As shown in FIG. 5 (d), after the banknote passes between the optical sensors 17 and 18, when the banknote is stored in the storage unit 15, the change machine 1 energizes these optical sensors 17 and 18. Stop and stop driving. The output change timing from the optical sensor 17 is different from the output change timing from the optical sensor 18 within the bill passage period. As will be described later, the corner break detection unit 19 detects the presence of the corner break and the fact that this corner break is in the upper left.

  When a corner break is detected in Act A6 of FIG. 3, the change machine 1 passes the NO route, and in Act A8, information on the position of the corner break such as the upper front side (the upper left portion in the figure) is written in the memory. In Act A9, the change machine 1 causes the display 21 to display a square indicating a banknote, and lights or blinks the upper left portion of the square. The display 21 may display information such as the upper front side in characters. In Act A10, the change machine 1 conveys the thousand yen ticket to the end of the casing depth, and at the end of the change, the direction of travel is changed by 180 degrees to convey it back.

  If the banknote denomination identification result is negative in Act A3, the route passes through the NO route. In Act A11, the transport unit 16 returns the paper piece without storing the paper piece, and returns the paper piece from the deposit port 11 or the withdrawal port 13. The negative identification result means a fake coin, an old Japanese banknote or foreign banknote, or a piece of paper that cannot be determined.

  Next, a method for detecting that the corner break 32 is on the upper front side will be described. FIG. 6 is a time chart showing examples of outputs of the optical sensors 17 and 18, and corresponds to the example of FIG. FIG. 6A shows the output of the optical sensor 17 (upper sensor). FIG. 6B shows the output of the optical sensor 18 (lower sensor). The dimension of the corner fold 32 in the conveyance direction is w (FIG. 5C). In FIG. 6 (a), T represents a time length, and this is the time length required for the bill to pass through the vertical plane by the distance of the dimension w. The horizontal axis of Fig.6 (a) and FIG.6 (b) represents time. The time when the bill is inserted is the origin of the time axis. The moment when the trailing edge of the banknote passes through this vertical plane is the last.

  The period I represents a period until the front end of the bill reaches the position between the optical sensors 17 and 18 after the energization of the optical sensors 17 and 18 is started. Both optical sensors 17, 18 are on. Time point II represents the time when the front lower corner of the bill passes through the vertical plane. The optical sensor 17 is on. The state of the optical sensor 18 changes from the on state to the off state. The corner break detection unit 19 detects that the output of the optical sensor 17 is on at a time point II at which the optical sensor 17 is supposed to be turned off due to shielding.

  Time point III represents the moment when the bill advances from time point II by the dimension w. The state of the optical sensor 17 changes from the on state to the off state. The corner break detection unit 19 detects that the output of the optical sensor 17 has changed from on to off until the trailing edge of the bill passes through a vertical plane including the upper and lower light beams. The state of the optical sensor 18 remains on. The period IV represents a period until the banknote part on the rear end side passes through the vertical plane from the edge of the corner portion. The corner break detection unit 19 detects that the light beam of the optical sensor 17 remains off until the end of the period IV arrives.

From the example of FIG. 4, the corner break detection unit 19 detects that there is no corner break when the outputs of these optical sensors 17 and 18 change simultaneously within a period in which the bill passes through the vertical plane. On the other hand, in the example of FIGS. 5 and 6, the corner break detection unit 19 detects the following three points. During the period when the bill is passing through the vertical plane, the output changes of the optical sensors 17, 18 are not occurring simultaneously. On the other hand, that is, the on state of the optical sensor 17 has continued for a while, and the on state has changed to the off state. The optical sensor 17 was kept off until the end of this period. When these three points are established, the corner break detection unit 19 detects the corner break on the upper front side of the bill. The examples in FIGS. 5 and 6 are examples in the case where there is a corner fold on the front upper side of the banknote, but the corner fold detection unit is also used in each case where the corner fold is on the front lower side, the rear upper side and the rear lower side of the banknote. Reference numeral 19 designates a corner break using a logic as shown in Table 1 indicating whether or not the timings of changes in the outputs of the optical sensors 17 and 18 are the same.

  As described above, the change machine 1 is provided with the optical sensors 17 and 18 on the upper and lower portions on the conveyance path, and detects the presence or absence of corner breakage by observing the on / off timing of the optical sensors 17 and 18. In this case, it is possible to specify the location of the corner break when there is a corner break. As a result, the time required for the cashier to be rejected can be shortened.

  If the bill is inserted into the change machine 1 while the corner folds 32 are still present, the change machine 1 may not be able to accurately determine the denomination and may be rejected. The change machine 1 can quickly display and notify the cashier that the cause of the rejection is corner breakage. If the banknotes are rejected, the cashier will correct the banknotes and reinsert them. Cashier cashier checkout work can be supported without giving unnecessary effort to the cashier.

  In the above embodiment, the optical sensor 17 is provided vertically separated in the vertical direction orthogonal to the banknote transport direction and the casing width direction, but the main transport path 32 by the transport unit 16 is in the apparatus height direction. There may be a case where the main transport path 32 itself tilts left and right with respect to the banknote transport direction. In this case, the pair of optical sensors 17 are provided so as to be separated from each other in the bill short side direction within a plane orthogonal to the bill conveyance direction. These optical sensors 17 and 18 may be spaced apart from each other in a direction intersecting with both the bill conveyance direction and the housing width direction with an inclination angle.

  The corner break detection unit 19 turns on the operation of the optical sensors 17 and 18 immediately before the banknote arrives, and turns off the operation of these optical sensors 17 and 18 after the banknote passes. The operation may be always on.

  The arrangement of the light transmitter 17a and the light receiver 17b and the arrangement of the light transmitter 18a and the light receiver 18b can be variously changed. For example, a mirror that reflects the light beam from the light transmitters 17a and 18a may be provided. In this way, the degree of freedom in arrangement can be increased.

  The display device 31 may be provided in a POS terminal or an ECR (terminal device) that performs sales registration processing of sales commodities connected to the banknote depositing / withdrawing device instead of being provided in the banknote depositing / withdrawing device. The POS terminal and ECR can display the broken part of the rejected banknote. For example, a part of the error content can be displayed on the customer display. The POS terminal side can accumulate information on the occurrence position of corner breaks. For example, the store system collects occurrence position information from each checkout register together with a time stamp. Thereby, a history of abnormality can be left for each checkout register. By collecting the frequency of occurrence position information between a plurality of stores, it can be used for maintenance and maintenance of the change machine 1 for each store and for each cash register, or can be used as information on crime prevention.

  Although several embodiments have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
