Let Further, the control unit 80 has a function as a shutter closing control unit 80a. The shutter closing control unit 80a will be described later.

A-2. Configuration of the coin deposit / withdrawal mechanism 60:
FIG. 3 is an explanatory view of a part of the coin deposit / withdrawal mechanism 60. (A) in a figure is a side view, (b) is a top view. As shown in FIG. 3A, the ATM 10 is provided with a front panel 110 that constitutes a part of the casing, and the front panel 110 has an opening 120 as a coin handling port and a bill handling port. An opening (not shown) is formed. A coin container 130 is disposed inside the opening 120, and the opening 120 is opened and closed by a shutter member 140. That is, the shutter member 140 has a plate shape that is slightly larger than the opening 120, and is moved by the drive motor 61 (FIG. 2) to open or close the opening 120. Furthermore, the coin deposit / withdrawal mechanism 60 includes a lock mechanism 62 (FIG. 2) that locks the movement of the shutter member 140. These structures constitute a part of the coin deposit / withdrawal mechanism 60.

  FIG. 3B shows the positional relationship between the opening 120 and the shutter member 140. As shown in the figure, the opening 120 has a rectangular shape, and the opening 120 is opened and closed by moving the shutter member 140 in a first direction u along the vertical direction of the rectangle.

  Various sensors for determining the state of the opening 120 are provided around the opening 120. Examples of the various sensors include a shutter open detection sensor 150, a shutter close detection sensor 152, a both-side foreign object detection sensor 154, a tip side foreign object detection sensor 156, and a shutter small open position movement detection sensor 158.

  The shutter opening detection sensor 150 is a so-called limit switch, and detects that the shutter member 140 is at a position where the opening 120 is fully opened. The shutter closing detection sensor 152 is also a so-called limit switch, and detects that the shutter member 140 is in a position where the opening 120 is fully closed.

  The both-side foreign object detection sensor 154 includes a light projecting unit 154a and a light receiving unit 154b, and a light projecting unit 154a is provided on one inner edge 120a of both sides in the second direction v along the lateral direction of the opening 120. The light receiving portion 154b is disposed on the other inner edge 120b of both sides in the direction v of 2. Since the opening 120 is rectangular, the second direction v is orthogonal to the first direction u. Whether light emitted from the light projecting unit 154a can be received by the light receiving unit 154b or not can be determined whether foreign matter has entered the optical path LP from the light projecting unit 154a to the light receiving unit 154b. . The light projecting unit 154a and the light receiving unit 154b are paired to form one double-side foreign object detection sensor 154. Further, a plurality of the foreign object detection sensors 154 are arranged at equal intervals along the first direction u. The interval d1 between the adjacent foreign matter detection sensors 154 is, for example, 30 [mm], and is a distance that can detect that a hand has entered the moving range of the shutter member 140. This distance of 30 [mm] is merely an example, and can be changed to another distance as long as a human hand can be detected.

  A plurality of tip side foreign matter detection sensors 156 are also provided, and each tip side foreign matter detection sensor 156 includes a light projecting unit 156a and a light receiving unit 156b. The light projecting portion 156 a is provided at the tip portion 140 a of the shutter member 140, that is, the tip portion 140 a of the shutter member 140 when the shutter member 140 moves in the direction of closing the opening 120. The light receiving portion 156b is provided on the inner wall 120c facing the front end portion 140a of the shutter member 140, that is, the inner wall 120c on the side where the front end portion 140a of the shutter member 140 contacts when the opening 120 is fully closed. . Each tip side foreign matter detection sensor 156 detects that a foreign matter has entered the optical path from the light projecting portion 156a to the light receiving portion 156b. Note that the plurality of front end side foreign object detection sensors 156 are arranged in a line at equal intervals, and the number thereof is determined so as to be arranged with no gap as much as possible. In addition, the light projecting unit 156a is provided on the tip portion 140a of the shutter member 140 and the light receiving unit 156b is provided on the inner wall 120c of the opening 120. Instead, the light projecting unit 156a is provided on the inner wall 120c of the opening 120. The light receiving portion 156b may be provided at the tip portion 140a of the shutter member 140.

  The shutter small opening position movement detection sensor 158 is a sensor for detecting that the shutter member 140 has moved to the small opening position. “Small open position” means a position where the opening 120 is slightly opened, and the width d2 of the gap is smaller than that of a hand attached to a bag, a strap of a mobile phone, a hem of a bag, or the like. Even if a foreign object enters, it is a size that can be removed. In the present embodiment, the opening size is such that the width d2 of the gap from the inner wall 120c of the opening 120 is 5 [mm]. It should be noted that any value between 3 and 10 [mm] can be used instead of 5 [mm]. Specifically, the shutter small opening position movement detection sensor 158 includes a light projecting section and a light receiving section, and is arranged above and below a position corresponding to the above 5 [mm] in the moving path of the shutter member 140.

  The configuration including the shutter member 140, the control unit 80, and the various sensors 150 to 158 described above corresponds to the “shutter device” described in the “Summary of the Invention” section.

A-3. Shutter closing control process:
FIG. 4 is a flowchart showing a shutter closing control process executed by the control unit 80. This shutter closing control process is for realizing the function of the shutter closing control unit 80a shown in FIG. As shown in the drawing, when the process is started, the control unit 80 first unlocks the lock mechanism 62 that locks the shutter member 140 (step S110). Next, the control unit 80 rotates the drive motor 61 in the forward direction to move the shutter member 140 in the closing direction (step S120). The “closing direction” is a direction in which the opening 120 is closed, and corresponds to a lower direction in the first direction u in FIG.

  Subsequently, during the movement of the shutter member 140 in the closing direction, it is determined whether or not at least one of the both-side foreign object detection sensors 154 has detected a foreign object (step S130). The “foreign matter” here is assumed to be a human hand, and when hand pinching is detected by the both-side foreign matter detection sensor 154, the control unit 80 temporarily stops the drive motor 61 (step S140), and then the step. The process returns to S130.

  On the other hand, when it is determined in step S130 that no foreign matter is detected by the both-side foreign matter detection sensor 154, that is, when hand pinching is not detected, the control unit 80 advances the processing to step S150. Even when a foreign object is detected once in step S130, if the user removes the foreign object, it is determined that the foreign object is not detected in step S130 during repeated execution. In step S160, the control unit 80 determines whether or not the shutter close detection sensor 152 has been switched to the on state. Switching to the on state is when the opening 120 is fully closed, and until it is determined in step S150 that it is in the on state (that is, when it is determined not to be in the on state), step S120. The process is returned to and the movement of the shutter member 140 in the closing direction is continued. As a result, as shown in FIG. 5, the opening 120 is fully closed by the shutter member 140.

  When the opening 120 is fully closed, it is determined in step S150 that the shutter close detection sensor 152 is in the on state, and the control unit 80 advances the process to step S160, and the front-end foreign matter detection sensor 156 detects foreign matter. It is determined whether or not it has been detected. Here, when it is determined that the foreign object detection sensor 156 has not detected a foreign object, the closing operation of the shutter member 140 is normally completed, and the process proceeds to “END”, and this shutter opening control process is performed. finish.

  On the other hand, when it is determined in step S160 that the front-end foreign matter detection sensor 156 has detected a foreign matter, the drive motor 61 is rotated in the reverse direction to move the shutter member 140 in the opening direction, and the shutter member 140 is moved to the small opening position. Return (step S120). The “opening direction” is a direction in which the opening 120 is opened, and corresponds to the upper direction in the first direction u in FIG. Whether or not the shutter member 140 has moved to the small opening position is determined by whether or not the shutter small opening position movement detection sensor 158 is turned on (whether the shutter member 140 is detected). When moving to the small open position, the shutter member 140 is stopped. As a result, as shown in FIG. 6, since the opening 120 can have an opening with a width d2, the user can remove the small foreign matter F such as the strap once sandwiched by the shutter member 140 from the opening 120. it can.

  In the present embodiment, the opening having the width d2 described above is in a positional relationship so as to be hidden at the edge of the opening 120 when viewed from the upper side in the drawing. For this reason, the user can see that the shutter member 140 is fully closed, and the user does not feel uncomfortable.

  Returning to FIG. 4, after executing step S <b> 170, the control unit 80 determines whether or not the customer detection unit 70 detects a user (step S <b> 180). The process of S180 is repeated to wait for the user to leave the ATM 10. When the customer detection unit 70 no longer detects the user in step S180, the drive motor 61 is rotated forward to move the shutter member 140 in the closing direction, and the shutter member 140 is fully closed (step S190). Thereafter, assuming that the closing operation of the shutter member 140 is normally completed, the process proceeds to “END”, and this shutter opening control process is terminated.

A-4. Embodiment effect:
According to the ATM 10 of the first embodiment configured as described above, a relatively large foreign object such as a human hand is detected by the plurality of both-side foreign object detection sensors 154 while the shutter member 140 is moved in the closing direction. When the intrusion is detected, the movement of the shutter member 140 is stopped so that the foreign matter can be removed. Furthermore, when the shutter member 140 was fully closed, the front-end foreign matter detection sensor 156 detected entry of foreign matter having a size smaller than that of a hand, such as a string attached to a bag, a strap of a mobile phone, or a bag hem. Sometimes, the shutter member 140 is returned to the small open position so that small foreign matters can be removed. Therefore, according to the ATM 10 of the first embodiment, the closing operation of the shutter member 140 is completed in a state where not only a relatively large foreign object such as a hand but also a foreign object smaller in size than the hand remains in the opening 120. Can be prevented.

B. Second embodiment:
Next, a second embodiment of the present invention will be described. The ATM in the second embodiment is different from the ATM 10 in the first embodiment only in that it does not include the tip-side foreign object detection sensor 156 (FIG. 3B) in terms of hardware configuration. The hardware configuration is the same. In addition, about the same component, the same code | symbol as 1st Embodiment is attached | subjected and demonstrated below. On the other hand, for the software configuration, a shutter closing control process that is partially different from the shutter closing control process (FIG. 4) of the first embodiment is executed.

  FIG. 7 is a flowchart showing shutter closing control processing in the second embodiment. In the shutter closing control process, the processes in steps S110 to S140, S180, and S190 are the same as those in the shutter control process of FIG. As shown in the figure, when it is determined in step S130 that no foreign matter is detected by the both-side foreign matter detection sensor 154, the process proceeds to step S250, and the shutter small open position movement detection sensor 158 is turned on. That is, it is determined whether the shutter member 140 has reached the small opening position.

  If it is determined in step S250 that the shutter member 140 has reached the small opening position, the control unit 80 temporarily stops the drive motor 61 (step S260), and then proceeds to step S180. On the other hand, if it is determined in step S250 that the shutter member 140 has not reached the small opening position, the process returns to step S120, and steps S120 to S140 and S250 are repeatedly executed.

  According to the ATM of the second embodiment configured as described above, as in the first embodiment, while the shutter member 140 is being moved in the closing direction, a plurality of both-side foreign object detection sensors 154 cause a person to move. When a relatively large foreign object such as a hand is detected, the movement of the shutter member 140 is stopped so that the foreign object can be removed. Further, when the shutter member 140 reaches the small opening position, the movement of the shutter member 140 is stopped, and the opening 120 is opened to a small size, so that the string attached to the bag, the strap of the mobile phone, the bottom of the bag For example, foreign objects that are smaller in size than the hand can be removed. Therefore, according to the ATM of the second embodiment, as in the first embodiment, not only a relatively large foreign object such as a hand but also a foreign object having a size smaller than that of the hand remains in the opening 120. Completion of the closing operation of the member 140 can be prevented.

C. Third embodiment:
Next, a third embodiment of the present invention will be described. The ATM in the third embodiment has the same hardware configuration as the ATM 10 in the first embodiment. In addition, about the same component, the same code | symbol as 1st Embodiment is attached | subjected and demonstrated below. On the other hand, as for the software configuration, a shutter closing control process in which the shutter closing control process (FIG. 4) of the first embodiment is combined with the shutter closing control process (FIG. 7) of the second embodiment is executed.

In the third embodiment, the description of the flowchart showing the shutter closing control process is omitted, but this shutter closing control process basically performs the following process.
(I) When the shutter member 140 is moved in the closing direction, the movement of the shutter member 140 is detected when a plurality of foreign matter detection sensors 154 detect the entry of a relatively large foreign matter such as a human hand. So that the foreign matter can be removed (steps S110 to S140 in FIG. 4),
(Ii) When the shutter member 140 reaches the small opening position, the movement of the shutter member 140 is stopped, and the opening 120 is opened to a small size, so that the string attached to the bag, the strap of the mobile phone, the bag A foreign object having a size smaller than that of a hand such as a hem can be removed (steps S250, S260, S180, and S190 in FIG. 7).
(Iii) When the shutter member 140 is fully closed, the plurality of tip side foreign object detection sensors 156 may intrude foreign objects having a size smaller than that of a hand, such as a string attached to a bag, a mobile phone strap, or a bag hem. When detected, the shutter member 140 is returned to the small open position so that small foreign matter can be removed (S150 to S190 in FIG. 4).

  According to the ATM of the third embodiment configured as described above, as with the first and second embodiments, not only relatively large foreign objects such as hands, but also foreign objects smaller in size than the hands are opened. It is possible to prevent the closing operation of the shutter member 140 from being completed in the state where it remains at 120.
