  By the way, in said banknote processing machine, foreign materials, such as a coin excluded from the insertion slot, are collect | recovered in a container. In this way, in the case of collecting foreign matter such as coins in a container, when the collected foreign matter is a coin, it may be impossible to specify in which process the coin is collected.

  Therefore, an object of this invention is to provide the banknote processing machine which can identify whether it is the coin collect | recovered in which process.

  In order to achieve the above-mentioned object, the invention according to claim 1 includes a bill insertion slot on which a bill inserted through the insertion opening is placed with its end edge abutted against the bottom, and the insertion opening. A banknote handling machine having a shutter that can be opened and closed, the bottom opening being provided at the bottom and restricting the entry of banknotes and allowing the entry of coins, and detecting the presence or absence of an abnormal closing operation of the shutter And a closing operation abnormality detecting means, wherein a coin that has entered the bottom opening abuts on the shutter to inhibit the closing operation of the shutter.

  The invention according to claim 2 is the invention according to claim 1, wherein when the shutter is in the open state, the shutter is positioned below the banknote insertion slot, wraps around the banknote insertion slot from the open state, and is above the banknote insertion slot. The shutter is closed to close the closing opening, and the shutter is provided with a standing wall portion that rises when the shutter is in the open state, and is higher than the standing wall portion in the closing operation direction of the shutter in the open state. Provided on the downstream side is a restriction wall portion that restricts the entry of coins while allowing the entry of the standing wall portion, and the bottom opening portion is formed between the standing wall portion and the restriction wall portion of the shutter in an opened state. It is characterized by being sent in between.

  According to the first aspect of the present invention, when a bill is inserted into the bill insertion slot through the insertion opening in which the shutter is open to perform one process, coins are mixed in this bill. In this case, coins enter the bottom opening provided at the bottom of the bill insertion slot. When the shutter is closed in this one process, the coin comes into contact with the shutter and obstructs the closing operation, and the closing operation abnormality detecting means detects the abnormal closing operation of the shutter. Will do. Therefore, if an abnormality occurs in the closing operation of the shutter in one process and there is a coin that obstructs the closing operation of the shutter at that time, the coin can be specified as the coin mixed in the one process. . Therefore, it becomes possible to specify in which process the coins are collected. Moreover, since the mixed coins abut against the shutter and obstruct the closing operation, it is possible to detect the presence of mixed coins with a simple structure, and one process can be performed if the mixed coins are not removed. It is possible to prevent forgetting to collect coins.

  According to the second aspect of the present invention, when coins are fed between the standing wall portion and the regulating wall portion of the shutter whose bottom opening is in the open state, the standing wall portion moves to the regulating wall portion side by the closing operation of the shutter. Thus, the coin is pressed toward the regulation wall portion, and the regulation wall portion restricts the entry of the coin, thereby inhibiting the shutter closing operation. Therefore, it can be detected with a simpler structure that there is a mixed coin.

The cover member 55 is formed with a closing opening 59 at the position of the closing opening 19.

  As shown in FIGS. 1 and 4, a shutter 65 that can open and close these is provided between the closing opening 19 and the closing opening 59. The shutter 65 is disposed in a space between the cover member 55 and the pair of side wall portions 16 and the guide wall portion 51, and slides while being guided by these. When the shutter 65 is in the open state shown in FIG. 1, the shutter 65 is positioned vertically below the banknote insertion slot 11, and from this open state, the banknote insertion slot 11 is moved forward to move to the upper side of the banknote insertion slot 11 and shown in FIG. 4. In this manner, the closing opening 19 and the closing opening 59 are closed. The shutter 65 is made of synthetic resin, and has a flexible shutter main body 66 that opens and closes the input openings 19 and 59, and an opening that opens the input openings 19 and 59 as shown in FIG. And a standing wall portion 67 that rises upward from the rear end edge portion of the shutter main body portion 66 when in the state. The standing wall 67 extends in the left-right direction.

  When the shutter 65 is in an open state in which the closing openings 19 and 59 are opened, the standing wall portion 67 is positioned immediately before the upward extending portion 58, and the rear portion of the shutter main body portion 66 is above the horizontal cover portion 57. It is arranged horizontally. A restriction wall 52 is provided on the downstream side of the standing wall 67 in the closing operation direction of the shutter 65 in the open state, and the maximum diameter is between the standing wall 67 and the restriction wall 52 at this time. A gap wider than the diameter of the coin C (500 yen coin) is formed.

  When driven from this open state by the shutter drive motor 71 shown in FIG. 2, the shutter 65 has the shutter main body 66 passing between the cover member 55 and the guide wall portion 51, and then the cover member 55 and a pair of side walls. As shown in FIG. 4, the charging openings 19 and 59 are closed through the space between the portions 16. Here, as shown in FIG. 5, the standing wall portion 67 of the shutter 65 has a comb-like shape in which concave portions 68 and convex portions 69 are alternately arranged in the left-right direction, and the regulating wall portion 52 is a standing wall portion 67. So that the convex portion 69 of the standing wall portion 67 enters the concave portion 73 and the convex portion 74 that enters the concave portion 68 of the standing wall portion 67 have a comb-teeth shape alternately arranged in the left-right direction. . Grooves 75 following the respective recesses 73 are also formed in the guide wall 51 shown in FIG. 4, and the protrusions 69 of the standing wall 67 pass through the grooves 75. The restricting wall 52 restricts the entry of the coin C as shown in FIG. 5 while allowing the standing wall 67 to enter.

  As shown in FIG. 1, on the front side of the separation roller 29 and below the bottom portion 15, a lower extension portion 81 extending vertically downward from the front end portion of the separation roller 29 and a lower end edge portion of the lower extension portion 81 in front. A guide member 83 having an inclined extending portion 82 extending downward is provided. The lower end portion of the inclined extending portion 82 is located at a position directly above the standing wall portion 67 of the shutter 65 in the open state. The guide member 83 guides the coin C that has passed through the bottom opening 41 onto the shutter main body 66 between the standing wall 67 and the regulating wall 52 of the shutter 65 in the open state. In other words, by providing the guide member 83, the bottom opening 41 feeds the coin C that has entered between the standing wall 67 and the regulation wall 52 of the shutter 65 in the open state. The coin C that has entered the bottom opening 41 abuts against the standing wall portion 67 and the restriction wall portion 52 of the shutter 65 and is sandwiched between them, thereby inhibiting the closing operation of the shutter 65.

  An openable and closable foreign matter collection door 84 is provided on the side of the machine body, and the foreign matter collection door 84 receives the coin C on the shutter main body 66 between the standing wall portion 67 and the restriction wall portion 52 of the shutter 65. Opened when taken out.

  In the banknote handling machine according to the present embodiment, the close detection sensor 85 (closed operation abnormality detecting means) shown in FIG. 2 that detects whether the shutter 65 is in the closed state shown in FIG. 4 and the shutter 65 are shown in FIG. An open detection sensor 86 (closed operation abnormality detecting means) shown in FIG. 2 that detects whether or not the open state is shown, and the bill press drive motor 23 and the take-in drive motor based on the detection results of these and the bill detection sensor 24. 30 and a control unit 87 (closing operation abnormality detecting means) for controlling driving of the shutter drive motor 71 and the like, an operation unit 88 for receiving an operation input from the operator, and a display unit 89 for performing display for the operator. It has been.

  The control unit 87 starts the driving of the shutter drive motor 71 in the closing direction from the state in which the shutter 65 is detected to be in the open state, and the shutter 65 is in the closed state even after a predetermined time has elapsed. If this is not detected by the closing detection sensor 85, it is detected that there is an abnormality in the closing operation of the shutter 65.

  Conversely, the controller 87 starts driving the shutter drive motor 71 in the closing direction from the state where the opening detection sensor 86 detects that the shutter 65 is in the open state, and then closes the shutter 65 before the predetermined time has elapsed. When the close detection sensor 85 detects that the state has been reached, it is detected that there is no abnormality in the closing operation of the shutter 65. That is, the closing detection sensor 85, the opening detection sensor 86, and the control unit 87 detect the presence or absence of an abnormality in the closing operation of the shutter 65.

  Here, the detection of the presence or absence of an abnormality in the closing operation of the shutter 65 may be other than the above. For example, the drive current of the shutter drive motor 71 becomes a predetermined value or more after the shutter drive motor 71 starts to be driven in the closing direction and before the close detection sensor 85 detects that the shutter 65 is closed. Then, the control unit 87 detects that there is an abnormality in the closing operation of the shutter 65 and starts driving the shutter driving motor 71 in the closing direction, and then the closing detection sensor 85 detects that the shutter 65 has been closed. Until this time, if the drive current of the shutter drive motor 71 does not become a predetermined value or more, the control unit 87 may detect that there is no abnormality in the closing operation of the shutter 65.

  Next, the operation of the banknote handling machine of this embodiment will be described.

  When, for example, a deposit processing selection operation is input to the operation unit 88, the control unit 87 drives the shutter drive motor 71 shown in FIG. 2 from the standby state where the shutter 65 is closed as shown in FIG. Open. When the shutter 65 is detected by the open detection sensor 86, the control unit 87 stops the shutter drive motor 71. Then, as shown in FIG. 1, the shutter 65 is in a state where the closing openings 19 and 59 are opened. In this state, the operator inserts the bill S into the bill insertion slot 11 through the insertion openings 19 and 59. At this time, if the coins C are mixed in the inserted bills S, the mixed coins C are in the open state by passing through the bottom opening 41 and guided by the guide member 83 by their own weight. It reaches the shutter main body 66 between the standing wall 67 of the shutter 65 and the restriction wall 52.

  When the bill S is inserted into the bill insertion slot 11 as described above, the bill detection sensor 24 detects the bill S. When the banknote detection sensor 24 detects the banknote S, the control unit 87 enters a state of waiting for the depositing process execution operation, and causes the display unit 89 to display a display prompting the depositing process execution operation. In this state, when a depositing operation execution operation is input to the operation unit 88, the control unit 87 starts the closing operation of driving the shutter drive motor 71 to close the closing openings 19 and 59 of the shutter 65.

  At this time, if the coin C exists on the shutter main body 66 between the standing wall 67 and the restriction wall 52 as shown in FIG. 1, the standing wall 67 becomes the coin C as shown in FIG. 6. Is stopped in a state of being sandwiched between the control wall 52 and the control wall 52. Therefore, the shutter 65 is in the closed state even after a predetermined time has elapsed after the shutter drive motor 71 starts to be driven in the closing direction from the state in which the shutter 65 is detected to be in the open state. A state in which the detection is not detected by the closing detection sensor 85 occurs. As a result, the control unit 87 detects an abnormality in the closing operation of the shutter 65. Then, the control unit 87 starts driving the shutter drive motor 71 in the opening direction, and when the open detection sensor 86 detects the open state of the shutter 65, the control unit 87 stops the shutter drive motor 71 and causes the display unit 89 to have a foreign object. A display prompting the removal is displayed, and the execution operation of the deposit process is waited.

  Looking at this display, the operator opens the foreign matter collection door 84 on the side of the machine body and is on the shutter main body 66 between the standing wall 67 and the regulating wall 52 of the shutter 65 as shown in FIG. Take out the coin C. Then, when the depositing operation execution operation is input to the operation unit 88 again, the control unit 87 starts the closing operation of driving the shutter drive motor 71 to close the closing openings 19 and 59 of the shutter 65.

  Further, when the closing operation for closing the closing openings 19 and 59 of the shutter 65 is started by driving the shutter drive motor 71, the coin C is placed on the shutter main body 66 between the standing wall 67 and the restriction wall 52. If the vertical wall 67 does not exist, the shutter main body 66 closes the closing openings 19 and 59 as shown in FIG. At this time, the shutter 65 is closed before a predetermined time elapses after the shutter drive motor 71 is driven in the closing direction from the state in which the shutter 65 is detected to be in the open state. Is detected by the closing detection sensor 85. Then, the control unit 87 stops the shutter drive motor 71 and drives the bill press drive motor 23 to move the bill press 22 toward the rear wall 17, and presses the bill S against the kick roller 27. Next, the control unit 87 drives the take-in drive motor 30 to kick the take-out roller 27 sequentially from the rearmost banknote S toward the take-in port 20, and the take-in roller 28 and the separation roller 29. The banknotes S are separated one by one and fed to the rear depositing side conveyance path 35, and the depositing side conveyance path 35 conveys the banknotes S to a depositing processing mechanism (not shown) to perform a predetermined depositing process. become.

  As described above, when there is a coin C mixed with the banknote S, the banknote S is not taken into the machine until the coin C is removed, and thus the coin C is currently inserted into the banknote slot 11. It becomes clear that it was inserted with the banknote S that is being stored.

  According to the banknote handling machine according to the present embodiment described above, when the banknote S is inserted into the banknote insertion slot 11 in which the shutter 65 is open to perform one process, as shown in FIG. When the coin C is mixed in the banknote S, the coin C enters the bottom opening 41 provided in the bottom 15. When the shutter 65 is closed in this one process, the coin C comes into contact with the shutter 65 and inhibits the closing operation, and an abnormality in the closing operation of the shutter 65 caused thereby is detected as a closing detection sensor. 85, the open detection sensor 86 and the control part 87 will detect. Therefore, if an abnormality occurs in the closing operation of the shutter 65 in one process, and there is a coin C that obstructs the closing operation of the shutter 65 at that time, the coin C mixed with the coin C in the one process is included. Can be identified. Therefore, it becomes possible to specify which coin C is collected in which process. In addition, since the mixed coin abuts against the shutter 65 and inhibits its closing operation, it is possible to detect the presence of the mixed coin C with a simple structure and to remove the mixed coin C unless the mixed coin C is removed. Processing can no longer be performed and forgetting to collect coins C can be prevented.

  In addition, when the coin C is fed between the standing wall portion 67 and the regulating wall portion 52 of the shutter 65 in which the bottom opening portion 41 is in the open state, the standing wall portion 67 moves to the regulating wall portion 52 side by the closing operation of the shutter 65. As a result, the coin C is pressed toward the regulation wall 52, and the regulation wall 52 restricts the entry of the coin C, thereby inhibiting the closing operation of the shutter 65. Therefore, it can be detected with a simpler structure that there is a mixed coin C.

  In the above embodiment, the case where the coin C is mixed in the banknote S has been described as an example. However, when a foreign object such as a clip other than the coin C is mixed in the banknote S, the foreign object is similarly bottom opening. 41 falls between the standing wall portion 67 and the regulating wall portion 52 of the shutter 65 in the open state. Therefore, even when foreign matter other than the coin C is mixed in the bill S, the foreign matter inhibits the closing operation of the shutter 65 as in the case of the coin C.
