Abstract

To allow for detecting that a foreign matter has been caught while having a simpler configuration than the conventional one.SOLUTION: A shutter mechanism 32 has a nesting shape where a shutter facing part 44 is nested with a front end part of a shutter 31. As such, when an elongate foreign matter 50 is caught between the front end part of the shutter 31 and the shutter facing part 44, the foreign matter 50 prevents the movement of the shutter 31 to the closing direction, causing the shutter 31 to be left open. Thus, a shutter closing sensor 43 can detect that the foreign matter 50 has been caught between the front end part of the shutter 31 and the shutter facing part 44.SELECTED DRAWING: Figure 6

Description

  The present invention relates to a medium processing apparatus and an automatic transaction apparatus, and is suitable for application to, for example, an automatic teller machine (ATM) having a shutter in a cash handling port.

  In general, an automatic teller machine used in a financial institution or the like has a shutter provided at a cash handling port serving as a cash inlet or cash outlet and opens the cash handling port by opening the shutter. The cash handling opening is closed by closing. Further, such an automatic teller machine is provided with a shutter closing sensor for detecting whether or not the shutter is closed. For example, when it is not detected that the shutter is normally closed during the closing operation of the shutter, After the closing operation is stopped and the shutter is opened, the shutter closing operation is performed again.

  As such an automatic teller machine, when the shutter is closed, the frame forming the cash handling port and the shutter do not interfere with each other in consideration of the accuracy of each part, and the frame and the front end of the shutter in the closing direction. Some have a slight gap between them.

  By the way, if a slight gap is provided between the frame and the front end of the shutter when the shutter is closed in this way, elongated foreign matters such as earphone cords and straps for portable devices may be caught in the gap. is there. In this case, since the automatic teller machine detects that the shutter has been normally closed by the shutter close sensor, the shutter is closed while the foreign object is still sandwiched. As a result, the user cannot take out the earphone cord or the portable device strap from the automatic teller machine.

  Therefore, conventionally, a foreign object detection sensor for detecting a foreign object sandwiched between the frame and the front end part of the shutter is provided at the front end part in the closing direction of the shutter, and this foreign object detection sensor is provided between the frame and the front end part of the shutter. An automatic teller machine has been proposed in which when a foreign object is detected, the shutter closing operation is stopped and the shutter is opened, and then the shutter closing operation is performed again (for example, Patent Document 1). reference).

Japanese Patent Laying-Open No. 2015-5247

  However, in the conventional automatic teller machine, in addition to the shutter closing sensor, it is necessary to provide a dedicated foreign matter detection sensor for detecting the foreign matter sandwiched between the frame and the tip of the shutter, which increases the number of parts. The problem was that the cost of parts would increase.

  In consideration of the above points, the present invention intends to propose a medium processing apparatus and an automatic transaction apparatus that can detect that a foreign object is caught while having a simpler configuration than the conventional one. .

  In order to solve this problem, the present invention includes a frame having a medium handling port, a shutter that opens or closes the medium handling port by opening and closing, and a control unit that controls opening and closing of the shutter. Has a nesting portion that forms a nesting structure by meshing with a front end portion in the closing direction of the shutter in the closed state in which the medium handling port is closed by closing the shutter, and the control unit closes the shutter. The opening / closing of the shutter is controlled based on the detection result of the closing detecting means for detecting whether or not the shutter is closed.

  As described above, the frame and the front end portion in the closing direction of the shutter have a nested structure, so that when the foreign matter is sandwiched between the frame and the front end portion of the shutter, the shutter is not normally closed by the foreign matter. As a result, it is possible to detect that a foreign object has been sandwiched between the frame and the front end portion of the shutter by a closing detection unit that detects whether the shutter is closed without providing a dedicated detection unit.

  The present invention can realize a medium processing apparatus and an automatic transaction apparatus that can detect that a foreign object has been caught while having a simple configuration as compared with the related art.

The storage 25 (25A to 25E) and the reject storage 26 may be fixed to the lower frame 24 or may be detachable from the lower frame 24. Furthermore, the banknote depositing / dispensing machine 10 includes a banknote control unit 27 that performs overall control, a transport path 28 indicated by a thick line in the drawing connecting the sections, and a transport unit 29 that transports banknotes along the transport path 28. doing.

  The deposit / withdrawal unit 20 includes a banknote storage unit 30 that stores banknotes, and an opening at the upper end of the banknote storage unit 30 serves as a deposit / withdrawal port 5. The deposit / withdrawal unit 20 separates the banknotes stored in the banknote storage unit 30 one by one from the deposit / withdrawal port 5 and feeds them to the transport path 28, and the banknotes sent along the transport path 28 to the banknote storage unit 30. Accumulate in Further, the deposit / withdrawal unit 20 is provided with a shutter mechanism 32 having a shutter 31 that opens or closes the deposit / withdrawal port 5. By opening the shutter 31, the deposit / withdrawal port 5 is opened and the shutter 31 is closed. Then close the deposit / withdrawal port 5.

  The discrimination unit 21 is provided at a predetermined location on the conveyance path 28, reads various information from each bill by various sensors incorporated therein, and based on the obtained information, the authenticity of the bill, Determine the damage, denomination, transport status, etc.

  The temporary storage unit 22 employs, for example, a tape escrow method, and temporarily stores banknotes sent along the transport path 28 by winding them together with tape around the circumferential side surface of the cylindrical drum. The banknote wound around the side surface is peeled off together with the tape and fed out to the conveyance path 28.

  Each storage 25 (25A-25E) is the same structure, and is formed in the rectangular parallelepiped shape long in the up-down direction. In each storage 25 (25A to 25E), the denominations of banknotes to be stored are set in advance, and the banknotes that are normally determined by the discrimination unit 21 are transported along the transport path 28 according to the denominations. When this happens, it is stored inside. Moreover, each storage 25 (25A-25E) will isolate | separate the piled banknote one by one, and will feed it to the conveyance path 28, if the instruction | indication which pays out a banknote from the banknote control part 27 is received.

  The reject containers 23 and 26 are each formed in a rectangular parallelepiped shape. When the banknotes that have been determined to be abnormal by the discrimination unit 21 or banknotes that are not to be recycled are transported along the transport path 28, the reject boxes 23 and 26 accumulate and store them. In the example shown in FIG. 2, the reject store 26 is larger than the reject store 23, and the number of sheets that can be stacked is also increased.

  The transport unit 29 transports banknotes to each unit along the transport path 28 by a transport roller, a transport belt, or the like. In addition, the conveyance part 29 conveys a banknote in the direction which makes the transversal direction of a banknote a conveyance direction, for example.

  The configuration of the banknote depositing / dispensing machine 10 is as described above, and the banknote control unit 27 controls each unit based on the banknote discrimination result by the discrimination unit 21, so that banknote depositing processing and withdrawal are performed. Processing is to be performed.

  That is, the banknote depositing / dispensing machine 10 has a shutter 31 of the depositing / withdrawing unit 20 when a cash card or the like is inserted into the automatic teller machine 1 and a depositing transaction is selected via the operation display unit 6 at the time of depositing transaction. Open the deposit / withdrawal port 5 by opening.

  Thereafter, when a bill is inserted into the deposit / withdrawal unit 20 from the deposit / withdrawal port 5 by the customer, the bill depositing / dispensing machine 10 closes the shutter 31 and conveys the inserted bills one by one to the discrimination unit 21. Here, if the banknote conveyed from the depositing / withdrawing part 20 is normally discriminate | determined by the discrimination part 21, about the banknote, it will convey to the temporary storage part 22, and will be stored. On the other hand, the banknote abnormally determined to be a deposit reject banknote that is not suitable for deposit by the discrimination unit 21 is returned to the deposit / withdrawal unit 20 and returned to the customer by opening the shutter 31.

  Thereafter, when the deposit amount is confirmed by the customer's operation, the banknote depositing / dispensing machine 10 conveys the banknote stored in the temporary storage unit 22 to the discrimination unit 21 to determine the denomination. And the banknote depositing / withdrawing machine 10 conveys the banknote by which the money type was discriminate | determined to the storage 25 corresponding to the money type, and accommodates it.

  On the other hand, at the time of the withdrawal transaction, the banknote depositing / dispensing machine 10 inserts a cash card or the like into the automatic teller machine 1 by the customer, selects the withdrawal transaction via the operation display unit 6, and further, the PIN number, withdrawal When the amount of money is entered, the number of bills required for each denomination is recognized according to the requested amount. And according to the banknote number for every money type required for a customer's request amount, a banknote is drawn | fed out one by one from each storage 25 (25A-25E), and it conveys to the discrimination part 21. FIG.

  Here, the banknote depositing / withdrawing machine 10 conveys the banknote normally determined by the discrimination unit 21 to the depositing / withdrawing unit 20, while the discrimination unit 21 determines that the banknote is a withdrawal reject banknote that is not suitable for withdrawal. Banknotes are transported to the temporary storage unit 22 for storage.

  And the banknote depositing / withdrawing machine 10 will open the deposit / withdrawal port 5 by opening the shutter 31, if the banknote for the amount of money to withdraw is integrated | stacked on the deposit or withdrawal part 20. FIG. As a result, it becomes possible to receive the banknotes accumulated in the depositing / withdrawing unit 20, and the customer receives the banknotes. Then, the banknote depositing / withdrawing machine 10 conveys and stores the withdrawal reject banknotes stored in the temporary storage unit 22 to the reject store 23 or the reject store 26. Thus, the banknote depositing / withdrawing machine 10 performs banknote depositing / withdrawing processing.

[1-2. Configuration of shutter mechanism of deposit / withdrawal unit]
Next, the configuration of the shutter mechanism 32 provided in the deposit / withdrawal unit 20 will be described with reference to partial cross-sectional views shown in FIGS. 3A and 3B are partial cross-sectional views when the shutter mechanism 32 is viewed from the left side. The shutter mechanism 32 supports the respective parts and forms the banknote storage part 30 and the deposit / withdrawal port 5 positioned at the upper end of the banknote storage part 30 (side frames 40S on the left and right sides, front frame 40F, upper frame 40U) The customer's hand is sandwiched between the shutter 31 that covers the deposit / withdrawal port 5, the guide groove 41 that guides opening / closing of the shutter 31, and the front end portion (tip portion in the shutter closing direction) of the shutter 31 and the frame 40. A hand scissors detecting sensor 42 for detecting whether or not the customer's hand is present on the movement locus of the front end portion of the shutter 31 and a shutter closing sensor 43 for detecting whether or not the shutter 31 is closed. doing.

  The guide groove 41 is provided opposite to the upper part of the inner surface of the left and right side frames 40 </ b> S that form the left and right side surfaces of the banknote accommodating part 30, and from the vicinity of the front end of the deposit / withdrawal port 5 to the rear end of the deposit / withdrawal port 5. It extends to the rear of the deposit / withdrawal port 5 from there. The left and right guide grooves 41 have an arc shape having a length about twice as long as the length of the deposit / withdrawal port 5 in the front-rear direction, and the length in the vertical direction (this width is defined as the width) from the front end to the rear end. ) Are the same.

  The shutter 31 is configured around a plate-like main body portion 31A having a size covering the deposit / withdrawal port 5, and a total of four shutters, one on each of the front and rear sides of the left and right side surfaces of the main body portion 31A. The cylindrical projection 31B is provided. The shutter 31 is supported by the frame 40 such that the left and right protrusions 31B are fitted in the left and right guide grooves 41 so that the shutter 31 can move in the front-rear direction along the guide grooves 41 (that is, can be opened and closed). The diameter of the protrusion 31B of the shutter 31 is substantially the same as the width of the guide groove 41, and the vertical position of the shutter 31 is regulated by the guide groove 41.

  The shutter 31 is movable in the front-rear direction between a position where the front protrusion 31B contacts the front end of the guide groove 41 and a position where the rear protrusion 31B contacts the rear end of the guide groove 41. It is moved (that is, opened and closed) by a driving force from a driving motor (not shown). For example, as shown in FIG. 3A, the shutter 31 is completely closed when the front projection 31B is positioned at the front end of the guide groove 41. At this time, the cash inlet / outlet 5 is closed. To do. On the other hand, as shown in FIG. 3B, for example, the shutter 31 is fully opened when the rear protrusion 31B is located at the rear end of the guide groove 41. 5 is released.

  Further, the shutter 31 has a thickness at the front end of the main body 31A that is about half of that of the main body 31A (that is, about half of the length in the vertical direction) and has a length in the front-rear direction that is longer than that of the main body 31A. A plate-like claw portion 31C extending from the left end to the right end of the main body portion 31A is provided sufficiently short. The upper surface of the claw portion 31C is one step lower than the upper surface of the main body portion 31A, and the lower surface is flush with the lower surface of the main body portion 31A. That is, the front end portion of the shutter 31 has a stepped shape including the main body portion 31A and the claw portion 31C. On the other hand, an upper portion of the inner surface 44 of the front frame 40F that forms the front end of the deposit / withdrawal port 5 and faces the claw portion 31C of the shutter 31 (referred to as a shutter facing portion) 44 is slightly larger than the claw portion 31C. A groove 45 recessed in the closing direction is provided. The groove 45 has a U-shaped cross section extending in the left-right direction according to the shape of the claw portion 31C.

  When the shutter 31 is closed, the claw portion 31C located at the front end in the closing direction enters the groove 45. When the shutter 31 is in the closed state, the shutter 31 enters the groove 45 as shown in a partially enlarged view in FIG. The upper surface, front surface, and lower surface of the claw portion 31 </ b> C are surrounded by the upper wall surface, the front wall surface, and the lower wall surface of the groove 45. That is, when the shutter 31 is in the closed state, the shutter facing portion 44 of the front frame 40F is engaged with the claw portion 31C so as to sandwich the claw portion 31C of the shutter 31 in the vertical direction, and together with the claw portion 31C. It is a nesting part which forms a nesting structure. In other words, in the shutter mechanism 32, the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40 </ b> F are directions in which bills are inserted into the deposit / withdrawal port 5 (or directions in which bills are taken out from the deposit / withdrawal port 5). It has a nested shape that meshes alternately in the vertical direction. The reason why the front end portion of the shutter 31 and the shutter facing portion 44 are nested will be described later.

  The shutter facing portion 44 of the front frame 40F and the front end portion of the shutter 31 (the front end of the main body portion 31A and the claw portion 31C) are in the closed state in consideration of the accuracy of each component so that they do not interfere with each other. In addition, a slight gap (for example, a gap of about several mm) S1 is formed between them.

  4B, the shutter facing portion 44 includes a frame upper surface 46 located above the groove 45, a groove 45, and a frame lower surface 47 located below the groove 45. The frame upper surface 46 located above 45 is slightly forward of the frame lower surface 47 located below the groove 45. Further, the corners of the frame lower surface 47 and the lower wall surface of the groove 45 have a chamfered gradient shape.

  Further, as shown in FIG. 3A, a protrusion 31 </ b> D that protrudes upward is provided at the rear end of the upper surface of the shutter 31. On the other hand, a protrusion 48 protruding downward is provided at the front end portion of the upper frame 40U that forms the rear end of the deposit / withdrawal port 5. The protrusion 31D of the shutter 31 is positioned in the vicinity of the rear of the protrusion 48 of the upper frame 40U when the shutter 31 is in the closed state, so that the protrusion 31D enters and exits from the gap between the shutter 31 and the upper frame 40U. The inside of the metal part 20 cannot be directly visually recognized.

  Furthermore, a plate-like detector 31E that protrudes downward is provided at the rear end of the lower surface of the shutter 31. The detector 31E is a member that turns on the shutter close sensor 43. On the other hand, the shutter closing sensor 43 is, for example, a photoelectric sensor, and includes a light emitting unit and a light receiving unit (not shown in the figure) that are disposed to face each other in the left-right direction. The shutter closing sensor 43 is provided below the rear end of the shutter 31 in the closed state, and the detector 31E of the shutter 31 in the closed state is positioned between the light emitting unit and the light receiving unit. Yes.

  That is, when the shutter 31 is in the closed state, the shutter close sensor 43 is turned on when the optical axis extending in the left-right direction between the light emitting unit and the light receiving unit is blocked by the detector 31E of the shutter 31. Yes. Therefore, when the shutter close sensor 43 is turned on, it means that the shutter 31 is closed (that is, the shutter is closed).

  The hand shearing detection sensor 42 is also a photoelectric sensor, for example, and includes a light emitting unit and a light receiving unit (not shown in the figure) disposed opposite to the left and right sides of the banknote storage unit 30. The hand shear detection sensor 42 is provided in the vicinity of the front end of the guide groove 41 on the movement trajectory of the front end of the shutter 31, and has an optical axis extending in the left-right direction between the light emitting unit and the light receiving unit. It is turned on by being blocked by the customer's hand. Therefore, if the hand shear detection sensor 42 is turned on, it means that there is a customer's hand or the like between the shutter 31 and the shutter facing portion 44 of the front frame 40F. The configuration of the shutter mechanism 32 is as described above.

  Here, the closing operation of the shutter 31 by the shutter mechanism 32 will be briefly described. The shutter 31 starts to move in the shutter closing direction (forward) indicated by the arrow A from the open state shown in FIG. Thereafter, as shown in FIG. 3A, the shutter 31 stops moving under the control of the bill control unit 27 when the front protrusion 31 </ b> B moves to the front end of the guide groove 41. At this time, the shutter 31 is closed.

  At this time, as shown in the enlarged view of FIG. 4A, the shutter 31 stops at a position where the front end of the detector 31E enters the distance X in the closing direction from the optical axis L1 of the shutter closing sensor 43. ing. That is, the shutter closing sensor 43 is turned on when the position of the shutter 31 is between a position just before the distance X and a position where the shutter 31 is closed.

  When the shutter 31 is in the closed state, the shutter 31 stops at a position where the front end of the claw portion 31C enters the groove 45 by a distance Y as shown in the enlarged view of FIG. It has become. This distance Y is also the distance in the closing direction from the frame upper surface 46 of the front frame 40F to the front end of the claw portion 31C entering the groove 45. Further, in the shutter mechanism 32, the position, size, and shape of each part are selected so that the distance Y is greater than the distance X.

  Since the distance Y> the distance X, as shown in FIG. 5, the shutter 31 is in a position where the front end of the detector 31E reaches the optical axis L1 of the shutter close sensor 43 during the closing operation (that is, the shutter close sensor). The front end of the claw portion 31C reaches the groove 45 of the front frame 40F at a position in front of the position detected by 43 as being closed. The reason why distance Y> distance X will be described later. The closing operation of the shutter 31 by the shutter mechanism 32 is as described above. As will be described in detail later, in the shutter mechanism 32, when the hand shear detection sensor 42 is turned on during the closing operation of the shutter 31, and when the shutter closing sensor 43 is not turned on, the shutter 31 is temporarily moved. After opening, the shutter 31 is closed again.

  By the way, as shown in FIG. 6, an elongated foreign object 50 having a thickness of several millimeters, such as an earphone cord or a strap for a portable device, hangs down from the deposit / withdrawal port 5 to the banknote storage unit 30 to the banknote storage unit 30. And the foreign matter 50 does not block the optical axis of the hand shear detection sensor 42, the closing operation of the shutter 31 is started in a state where the foreign matter 50 remains in the bill housing part 30. In this case, the foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F.

  Here, in the shutter mechanism 32, as described above, the front end portion of the shutter 31 and the shutter facing portion 44 have a nested structure, so that the foreign matter 50 is a groove between the claw portion 31C of the shutter 31 and the shutter facing portion 44. 45 to prevent the shutter 31 from moving in the closing direction. As a result, the shutter 31 stops in a state where the front end of the claw portion 31C is located in the vicinity of the entrance of the groove 45 (that is, a slightly opened state), and does not become a closed state.

  More specifically, the foreign object 50 sandwiched between the shutter 31 and the shutter facing portion 44 attempts to deform by receiving a force in the closing direction of the shutter 31 from the claw portion 31C of the shutter 31. Deformation is suppressed by receiving a force in the direction opposite to the claw portion 31C (that is, a force in the opening direction of the shutter 31) from the frame upper surface 46 and the frame lower surface 47 positioned above and below the portion 31C. Thereby, the foreign substance 50 maintains the shape so as to block the entrance of the groove 45. As a result, the shutter 31 stops in a state where the front end of the claw portion 31C is in contact with the foreign object 50 and is located near the entrance of the groove 45.

  Further, as described above, the shutter mechanism 32 has the distance Y> the distance X, and the claw portion 31C is provided before the front end of the detector 31E reaches the optical axis L1 of the shutter close sensor 43 when the shutter 31 is closed. The front end of the frame reaches the groove 45 of the front frame 40F. As a result, in the shutter mechanism 32, the elongated foreign object 50 is sandwiched between the shutter 31 and the shutter facing portion 44, and the shutter 31 stops in a state where the front end of the claw portion 31 </ b> C of the shutter 31 is located near the entrance of the groove 45. In this case, the front end of the detector 31E has not yet reached the optical axis L1 of the shutter close sensor 43, and the shutter close sensor 43 is not turned on. In other words, in the shutter mechanism 32, when the elongated foreign object 50 is sandwiched between the shutter 31 and the shutter facing portion 44, the shutter 31 is not closed and the shutter closing sensor 43 is not turned on. If the shutter closing sensor 43 is not turned on even after the shutter 31 is closed, the shutter mechanism 32 once opens the shutter 31 and then closes the shutter 31 again.

  As shown in FIG. 6, when the elongated foreign object 50 is sandwiched between the shutter 31 and the shutter facing portion 44, the claw portion 31 </ b> C of the shutter 31 slightly enters the groove 45 of the shutter facing portion 44. Stop at the right position. Therefore, at this time, in order to ensure that the shutter closing sensor 43 is not turned on, the distance Y is set to a value larger than the distance X by the distance that the claw portion 31C enters the groove 45 with the foreign object 50 sandwiched therebetween. It is desirable to do.

  As described above, in the shutter mechanism 32, when the shutter 31 is in the closed state, the thickness is about the same as the gap S1 (for example, about several mm) provided between the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F. Even when a long and narrow foreign object 50 having a thickness is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F during the closing operation of the shutter 31, this can be detected by the shutter closing sensor 43. It has become.

[1-3. Functional configuration of automatic teller machine]
Next, the functional configuration of the automatic teller machine 1 will be described using the block diagram shown in FIG. Here, for convenience of explanation, only the part related to the control of the shutter 31 of the deposit / withdrawal unit 20 in the functional configuration of the automatic teller machine 1 will be described. The automatic teller machine 1 includes a main control unit 9, an operation display unit 6, a bill control unit 27, a drive motor 51 serving as a power source for opening and closing the shutter 31, A shear detection sensor 42 and a shutter closing sensor 43 are provided.

  The main control unit 9 is a part that controls the automatic teller machine 1 as a whole. The main control unit 9 gives instructions to the banknote control unit 27 according to the contents of customer operations performed on the operation display unit 6, and the banknote control unit 27. Various types of information are displayed on the operation display unit 6 in response to the notification from. The banknote control unit 27 is a part that controls the banknote depositing and dispensing machine 10 and also functions as a shutter control unit 52 that controls opening and closing of the shutter 31.

  The shutter control unit 52 controls the drive motor 51 to open / close the shutter 31 based on the instruction from the main control unit 9, the detection result of the hand shear detection sensor 42, and the detection result of the shutter close sensor 43. Control. The functional configuration of the automatic teller machine 1 is as described above.

[1-4. Shutter closing process]
Next, the procedure of the process of closing the shutter 31 (called the shutter closing process) executed by the shutter control unit 52 will be described with reference to the flowchart shown in FIG. First, it is assumed that the shutter 31 is in an open state. Here, for example, when the main controller 9 instructs the shutter controller 52 to close the shutter 31 of the deposit / withdrawal unit 20, the shutter controller 52 controls the drive motor 51 to start the shutter 31 closing operation in step SP1. Then, counting of the number of pulses included in the pulse signal for driving the drive motor 51 is started. Thereafter, the shutter control unit 52 monitors the position of the shutter 31 from the amount of movement of the shutter 31 estimated based on the number of pulses of the drive motor 51.

  In subsequent step SP2, it is determined whether or not the hand shearing detection sensor 42 is turned on. Here, if the hand shearing detection sensor 42 is on, this means that a customer's hand exists between the shutter 31 and the shutter facing portion 44 of the front frame 40F. In this case, the shutter controller 52 obtains an affirmative result at step SP2 and proceeds to step SP3. In step SP3, the shutter control unit 52 interrupts the closing operation of the shutter 31 and executes the opening operation of the shutter 31, thereby opening the shutter 31 to the open state (or halfway), and then returning to step SP1. The closing operation of the shutter 31 is started again. At this time, the pulse count is once reset.

  As described above, when the hand shear detection sensor 42 is turned on, the shutter control unit 52 sandwiches the customer's hand between the shutter 31 and the shutter facing portion 44 of the front frame 40F. In order to prevent this, the closing operation of the shutter 31 is interrupted and the shutter 31 is opened.

  On the other hand, when the hand shear detection sensor 42 is off, the shutter control unit 52 obtains a negative result in step SP2 and proceeds to step SP4. In step SP4, the shutter controller 52 causes the amount of movement of the shutter 31 based on the number of pulses of the drive motor 51 to reach a position before the front end of the shutter 31 blocks the optical axis of the hand shear detection sensor 42. It is determined whether or not a predetermined amount required for the process has been reached. Here, if the amount of movement of the shutter 31 based on the number of pulses does not reach the predetermined amount required for the front end of the shutter 31 to reach a position before the optical axis of the hand shear detection sensor 42 is reached, the shutter The control unit 52 returns to step SP2 and continues monitoring by the hand scissors detection sensor 42. On the other hand, in the shutter control unit 52, the movement amount of the shutter 31 based on the number of pulses is blocked by the front end portion of the shutter 31 while the hand detection sensor 42 is off, and the optical axis of the hand detection detection sensor 42 is blocked. When the predetermined amount required to reach the front position is reached, an affirmative result is obtained in step SP4, the process proceeds to step SP5, and monitoring by the hand scissors detection sensor 42 is stopped.

  In subsequent step SP6, the shutter controller 52 determines whether or not the shutter closing sensor 43 is turned on until the amount of movement of the shutter 31 based on the number of pulses reaches a predetermined amount required for the shutter 31 to be closed. To do. If the shutter close sensor 43 is on, this means that the shutter 31 is closed. In this case, the shutter control unit 52 obtains a positive result in step SP6, moves to step SP7, ends the closing operation of the shutter 31, and ends a series of shutter closing processes.

  On the other hand, if the shutter close sensor 43 is not turned on before the amount of movement of the shutter 31 based on the number of pulses reaches a predetermined amount required for the shutter 31 to be in the closed state, this means This means that the closing operation of the shutter 31 is hindered by something that cannot be detected by the detection sensor 42. For example, as described above, when the elongated foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F, the movement amount of the shutter 31 based on the number of pulses is closed. Even when a predetermined amount required to enter the state is reached, the shutter closing sensor 43 is not turned on.

  In this case, the shutter control unit 52 obtains a negative result in step SP6 and proceeds to step SP3. In step SP3, the shutter control unit 52 interrupts the closing operation of the shutter 31 and executes the opening operation of the shutter 31, thereby opening the shutter 31 to the open state (or halfway). By doing so, the shutter control unit 52 allows the customer to recognize that the shutter 31 cannot be closed normally, and removes the foreign matter 50 entering the banknote storage unit 30, for example. Thereafter, the shutter control unit 52 returns to step SP1 and starts the closing operation of the shutter 31 again. At this time, the pulse count is once reset. The procedure of the shutter closing process is as described above.

  Here, it is confirmed whether or not the shutter closing sensor 43 is on until the amount of movement of the shutter 31 based on the number of pulses reaches a predetermined amount necessary for the shutter 31 to close. However, the present invention is not limited to this. For example, the time from the start of the closing operation of the shutter 31 is counted, and it is confirmed whether or not the shutter closing sensor 43 is on until a predetermined time required until the shutter 31 is closed. Good.

[1-5. Summary and Effect]
As described above, the shutter mechanism 32 according to the first embodiment has the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F nested so that when the shutter 31 is in the closed state, The claw portion 31 </ b> C located at the front end of 31 enters the groove 45 of the shutter facing portion 44. Thus, in the shutter mechanism 32, when the elongated foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44 during the closing operation of the shutter 31, the foreign object 50 becomes the claw portion 31 </ b> C of the shutter 31. And the groove 45 of the shutter facing portion 44, the movement of the shutter 31 in the closing direction is prevented, and the shutter 31 is not normally closed.

  Thereby, in the shutter control unit 52, when the shutter 31 is in the closed state, the elongated foreign object 50 having a thickness of about the gap S1 provided between the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F is The shutter closing sensor 43 can detect that the shutter 31 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44.

  Thus, in the shutter mechanism 32, the front end portion of the shutter 31 is opposed to the front end portion of the shutter 31 without providing a dedicated foreign matter detection sensor for detecting the foreign matter sandwiched between the shutter 31 and the shutter facing portion 44. It can be detected that the foreign object 50 is sandwiched between the portion 44 and the portion 44.

  Here, FIG. 9A shows a shutter mechanism 61 having a shutter facing portion 60 having a shape different from the shutter facing portion 44 as a comparison target of the shutter mechanism 32. The shutter facing portion 60 of the shutter mechanism 61 connects the frame upper surface 62, the frame lower surface 63 positioned below and behind the frame upper surface 62, and the frame upper surface 62 and the frame lower surface 63. And a frame inner surface 64 orthogonal to each other, and has a stepped shape as a whole. Thus, in the shutter mechanism 61, the front end portion of the shutter 31 and the shutter facing portion 60 have a shape different from the nested shape.

  In the shutter mechanism 61, when the shutter 31 is in the closed state, the claw portion 31C of the shutter 31 is positioned near the upper part of the frame inner surface 64. At this time, the front and lower surfaces of the claw portion 31C, A slight gap S <b> 1 is formed between the frame upper surface 62 and the frame middle surface 64.

  That is, unlike the shutter mechanism 32, the shutter mechanism 61 remains open on the upper surface side of the claw portion 31C of the shutter 31 even when the shutter 31 is closed. Therefore, in the shutter mechanism 61, as shown in FIG. 9B, when the elongated foreign object 50 enters between the front end portion of the shutter 31 and the shutter facing portion 60 during the closing operation of the shutter 31, The deformation of the foreign matter 50 cannot be suppressed between the front end portion and the shutter facing portion 60, and the foreign matter 50 is deformed along the gap S1 between the front end portion of the shutter 31 and the shutter facing portion 60 and enters the gap S1. The shutter 31 closes normally.

  As described above, in the shutter mechanism 61, when the elongated foreign object 50 is sandwiched between the shutter 31 and the shutter facing portion 60, the shutter 31 is normally closed as it is, so that the foreign object 50 is sandwiched. It cannot be detected by the shutter closing sensor 43.

  As is clear from the comparison with the shutter mechanism 61, the shutter mechanism 32 of the present embodiment detects the foreign object 50 by making the shutter facing portion 44 a nested shape that nests with the front end portion of the shutter 31. The shutter closing sensor 43 can detect that the foreign object 50 has been sandwiched between the shutter 31 and the shutter facing portion 44 without providing a dedicated sensor for this purpose.

  According to the above configuration, the automatic teller machine 1 and the banknote depositing / dispensing machine 10 having the shutter mechanism 32 have a simpler configuration as compared with the related art, but the foreign matter 50 is between the shutter 31 and the shutter facing portion 44. It is possible to detect being caught.

[2. Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, the configuration of the shutter mechanism provided in the deposit / withdrawal unit 20 is an embodiment different from the first embodiment, the configuration of parts other than the shutter mechanism, and the shutter closing process. Since this procedure is the same as that of the first embodiment, detailed description thereof is omitted.

[2-1. Configuration of shutter mechanism]
FIGS. 10A and 10B show the configuration of the shutter mechanism 100 of the second embodiment corresponding to the shutter mechanism 32 of the first embodiment. FIGS. 10A and 10B are partial cross-sectional views corresponding to FIGS. 3A and 3B. The same portions are denoted by the same reference numerals and description thereof will be omitted as appropriate.

  As shown in FIGS. 10A and 10B, the shutter mechanism 100 guides the frame 40 (the left and right side frames 40S, the front frame 40F, the upper frame 40U), the shutter 31, and the opening and closing of the shutter 31. A guide groove 101, a hand shear detection sensor 42, and a shutter closing sensor 43.

  The guide groove 101 is a portion corresponding to the guide groove 41 of the shutter mechanism 32, and the width of the front portion of the guide groove 41 (length in the vertical direction) is increased. That is, the front width of the guide groove 101 is larger than the diameter of the protrusion 31B provided on the main body 31A of the shutter 31, and the width of the portion other than the front is substantially the same as the diameter of the protrusion 31B. ing.

  The shutter 31 is supported by the frame 40 so that the left and right protrusions 31B are fitted in the left and right guide grooves 101 so as to be movable in the front-rear direction along the guide grooves 101 (that is, openable and closable). Further, the shutter 31 has a width of the front portion of the guide groove 101 larger than the diameter of the protrusion portion 31B, so that the front protrusion portion 31B is positioned at the front portion of the guide groove 101 (that is, close to a closed state). Within the width of the front portion of the guide groove 101, the front portion of the shutter 31 can be rotated in the vertical direction around the rear protrusion 31B.

  The front frame 40F is provided with a shutter facing portion 102 corresponding to the shutter facing portion 44 of the shutter mechanism 32 at the upper part of the inner surface. As shown in the enlarged view of FIG. 12B, the shutter facing portion 102 includes a groove 103, a frame upper surface 104 located above the groove 103, and a frame lower surface 105 located below the groove 103. The frame upper surface 104 is located slightly ahead of the frame lower surface 105.

  The groove 103 is a portion corresponding to the groove 45 of the shutter mechanism 32, and has a U-shaped cross section extending in the left-right direction according to the shape of the claw portion 31C. The groove 103 is slightly larger than the claw portion 31 </ b> C, and the length in the vertical direction (interval between the upper wall surface and the lower wall surface) is smaller than that of the groove 45.

  When the shutter 31 is closed, the claw portion 31C enters the groove 103, and when the shutter 31 is completely closed, the upper surface, front surface, and lower surface of the claw portion 31C entering the groove 103 are the upper wall surface of the groove 103, Surrounded by the front wall and the lower wall. Thus, like the shutter facing portion 44, the shutter facing portion 102 meshes with the claw portion 31C so as to sandwich the claw portion 31C of the shutter 31 in the vertical direction when the shutter 31 is closed. The nest portion forms a nested structure together with the claw portion 31C. That is, in the shutter mechanism 100, the front end portion of the shutter 31 and the shutter facing portion 102 of the front frame 40F are nested.

  Further, the shutter facing portion 102 is a lower inclined surface 106 having a gradient shape in which corners between the lower wall surface of the groove 103 and the frame lower surface 105 are chamfered, and between the upper wall surface of the groove 103 and the frame upper surface 104. The corner portion is also an upper inclined surface 107 having a chamfered gradient shape. That is, the shutter facing portion 102 has a divergent shape that becomes wider in the vertical direction as the entrance portion of the groove 103 is separated from the front wall surface of the groove 103. The configuration of the shutter mechanism 100 is as described above. Here, the upper inclined surface 107 and the lower inclined surface 106 are formed at the entrance portion of the groove 103, but not limited to this, only one of the upper inclined surface 107 and the lower inclined surface 106 is formed. It may be.

  Next, the closing operation of the shutter 31 by the shutter mechanism 100 will be briefly described. The shutter 31 starts moving in the shutter closing direction (forward) indicated by the arrow A from the open state shown in FIG. Thereafter, as shown in FIG. 11, when the front protrusion 31B moves to the front part of the guide groove 101, the shutter 31 can turn the front part of the shutter 31 up and down around the rear protrusion 31B. It becomes a state. At this time, the front portion of the shutter 31 rotates downward due to its own weight, so that the claw portion 31 </ b> C comes into contact with the lower inclined surface 106 of the shutter facing portion 102. Thereafter, when the shutter 31 further moves in the shutter closing direction, the claw portion 31C of the shutter 31 is guided to the groove 103 of the shutter facing portion 102 so as to rise above the lower inclined surface 106 of the shutter facing portion 102. As described above, the lower inclined surface 106 functions as a guide portion that guides the claw portion 31 </ b> C of the shutter 31 to the groove 103.

  Then, as shown in FIG. 10A, the shutter 31 stops moving under the control of the banknote control unit 27 when the front protrusion 31 </ b> B moves to the front end of the guide groove 101. At this time, the shutter 31 is closed.

  As described above, the shutter mechanism 100 has a configuration in which the claw portion 31C of the shutter 31 is guided to the groove 103 by the lower inclined surface 106 provided at the entrance portion of the groove 103 of the shutter facing portion 102, so that the closed state is achieved. In this case, the gap S1 between the claw portion 31C of the shutter 31 and the wall surface of the groove 103 can be made narrower than that of the shutter mechanism 32.

  Specifically, as shown in FIGS. 4B and 12B, in the shutter mechanism 32, when the shutter 31 is in the closed state, it is necessary to leave a gap S1 above, below, and in front of the claw portion 31C. On the other hand, in the shutter mechanism 100, the clearance S1 only needs to be provided above and in front of the claw portion 31C. Therefore, in the shutter mechanism 100, the distance d3 between the upper surface of the claw portion 31C and the upper wall surface of the groove 103, the distance d1 between the upper surface of the claw portion 31C and the upper wall surface of the groove 45 in the shutter mechanism 32, and the claw portion 31C The gap d2 between the lower surface and the lower wall surface of the groove 45 can be shortened to about half of the length, and as a result, the gap S1 between the upper surface side and the lower surface side of the claw portion 31C can be reduced in the entire gap S1. it can. That is, the shutter mechanism 100 can make the gap S1 between the front end portion of the shutter 31 and the shutter facing portion 102 narrower than that of the shutter mechanism 32.

  12A and 12B, when the shutter 31 is closed, the front end of the detector 31E enters from the optical axis L1 of the shutter close sensor 43 by a distance X in the closing direction. In addition, the front end of the claw portion 31C stops at a position where it enters the groove 103 by a distance Y. In the shutter mechanism 100, as in the shutter mechanism 32, the position, size, and shape of each part are selected so that the distance Y is greater than the distance X.

  Since the distance Y> the distance X, the shutter 31 has the front end of the claw portion 31C in the front frame 40F before the front end of the detector 31E reaches the optical axis L1 of the shutter close sensor 43 during the closing operation. The groove 103 is reached. The closing operation of the shutter 31 by the shutter mechanism 100 is as described above.

  By the way, as shown in FIG. 13, it is assumed that an elongated foreign object 50 having a thickness of about several millimeters is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 102 of the front frame 40F.

  Here, in the shutter mechanism 100, as described above, the front end portion of the shutter 31 and the shutter facing portion 102 have a nested structure, so that the foreign matter 50 is a groove between the claw portion 31C of the shutter 31 and the shutter facing portion 102. 103 to prevent the shutter 31 from moving in the closing direction. As a result, the shutter 31 stops in a state where the front end of the claw portion 31C is positioned near the entrance of the groove 103, and does not close.

  That is, in the shutter mechanism 100 as well as the shutter mechanism 32, the shutter closing sensor 43 is not turned on when the elongated foreign object 50 is sandwiched between the shutter 31 and the shutter facing portion 102. If the shutter closing sensor 43 is not turned on even after the shutter 31 is closed, the shutter mechanism 100 once opens the shutter 31 and then closes the shutter 31 again.

  As described above, in the shutter mechanism 100, when the shutter 31 is in the closed state, the elongated foreign object 50 having the same thickness as the gap S1 provided between the front end portion of the shutter 31 and the shutter facing portion 102 of the front frame 40F. However, even when the shutter 31 is closed between the front end portion of the shutter 31 and the shutter facing portion 102 of the front frame 40F, this can be detected by the shutter close sensor 43.

  Furthermore, in the shutter mechanism 100, as described above, the gap S1 provided between the front end portion of the shutter 31 and the shutter facing portion 102 when the shutter 31 is in the closed state can be made narrower than the shutter mechanism 32. . As a result, in the shutter mechanism 100, when the foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 102, the resistance force that the shutter 31 receives from the foreign object 50 increases, so that the shutter 31 is more reliably moved. Can be stopped. That is, the shutter mechanism 100 can more reliably detect that the foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 102 as compared with the shutter mechanism 32.

[2-2. Summary and Effect]
As described so far, the shutter mechanism 100 according to the second embodiment has the front end portion of the shutter 31 and the shutter facing portion 102 of the front frame 40F nested so that the shutter 31 is closed when the shutter 31 is in the closed state. A claw portion 31 </ b> C located at the front end of 31 enters the groove 103 of the shutter facing portion 102. In this way, in the shutter mechanism 100, when the elongated foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 102 during the closing operation of the shutter 31, the foreign object 50 becomes the claw portion 31C of the shutter 31. And the groove 103 of the shutter facing portion 102, the movement of the shutter 31 in the closing direction is prevented, and the shutter 31 is not normally closed.

  Thus, in the shutter mechanism 100, as in the first embodiment, a dedicated foreign matter detection sensor or the like for detecting the foreign matter sandwiched between the shutter 31 and the shutter facing portion 102 is not provided at the front end portion of the shutter 31. Thus, it can be detected that the foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 102.

  Further, the shutter mechanism 100 has a configuration in which the claw portion 31C of the shutter 31 is guided to the groove 103 by the lower inclined surface 106 provided at the entrance portion of the groove 103 of the shutter facing portion 102, so that the shutter mechanism 100 is in the closed state. The clearance S1 between the claw portion 31C of the shutter 31 and the wall surface of the groove 103 (that is, the nesting clearance) S1 can be made narrower than that of the shutter mechanism 32.

  Thus, in the shutter mechanism 100, when the foreign object 50 is sandwiched between the shutter 31 and the shutter facing portion 102, the resistance force that the shutter 31 receives from the foreign object 50 is increased, and the shutter 31 is more reliably stopped. Thus, it can be detected that the foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 102 more reliably than in the first embodiment.

[3. Third Embodiment]
Next, a third embodiment will be described. In the third embodiment, the configuration of the shutter mechanism provided in the deposit / withdrawal unit 20 is different from the first and second embodiments. Since it is the same as that of 1 embodiment, detailed description is abbreviate | omitted.

[3-1. Configuration of shutter mechanism]
FIGS. 14A and 14B show the configuration of the shutter mechanism 200 of the third embodiment corresponding to the shutter mechanism 32 of the first embodiment. 14A and 14B are partial cross-sectional views corresponding to FIGS. 3A and 3B, and the same portions are denoted by the same reference numerals and description thereof is omitted as appropriate.

  As shown in FIGS. 14A and 14B, the shutter mechanism 200 guides the frame 40 (the left and right side frames 40S, the front frame 40F, the upper frame 40U), the shutter 31, and the opening and closing of the shutter 31. A guide groove 41, a hand shear detection sensor 42, and a shutter closing sensor 43.

  Regarding the frame 40, the shutter 31, the guide groove 41, the hand shear detection sensor 42, and the shutter closing sensor 43, except that the protrusion 31D and the protrusion 48 are omitted from the shutter 31 and the upper frame 40U, respectively. The shutter mechanism 32 has the same configuration. In the shutter mechanism 200, the protrusion 31D and the protrusion 48 are omitted. However, like the shutter mechanism 32, these may be provided on the shutter 31 and the upper frame 40U.

  The shutter mechanism 200 is greatly different from the shutter mechanism 32 in that the shutter 31 is opened and closed inside one (or both) of the left and right side frames 40S as shown in FIGS. In addition, an open / close lock mechanism 201 is provided that locks the opening and closing of the shutter 31 and maintains the closed state when the shutter 31 is in the closed state. 15A shows a state where the shutter 31 is closed and locked, and FIG. 15B shows a state where the shutter 31 is open and not locked.

  The open / close lock mechanism 201 includes a drive motor 210 serving as a power source for opening and closing the shutter 31, a disk-shaped first gear 211 connected to the rotation shaft of the drive motor 210, and a disk connected to the first gear 211. -Shaped second gear 212, a square bar-shaped link gear 213 that is connected to the second gear 212 and moves in the front-rear direction as the second gear 212 rotates, and a link gear that guides the movement of the link gear 213 The guide groove 214 is rotatably connected to the link gear 213 and is connected to each of the first and second elongated plate-like links 215 that move in the front-rear direction together with the link gear 213, and the first link 215 and the shutter 31. A slender plate-like second link 216 that moves in the front-rear direction together with the first link 215, and the first link 215 and the second link 216 are rotatable. The first post guide groove 218 that guides the movement of the columnar first post 217 connected to the second column 217, and the movement of the columnar second post 219 that rotatably connects the second link 216 and the shutter 31. The second post guide groove 220 for guiding the lock and the lock detection sensor 221 for detecting whether or not the shutter 31 is locked.

  The second post guide groove 220 is provided outside the second half of the guide groove 41 provided inside the side frame 40 </ b> S and is connected to the second half of the guide groove 41. That is, the second post guide groove 220 and the second half of the guide groove 41 are formed as one circular hole extending in the front-rear direction. The first post guide groove 218 is positioned below the second post guide groove 220 and extends in the front-rear direction along the second post guide groove 220. The first post guide groove 218 is longer than the second post guide groove 220, and the front end is located in front of the front end of the second post guide groove 220. Further, the front end portion of the first post guide groove 218 is bent upward, and is generally L-shaped as a whole. Note that a portion protruding upward from the front end of the first post guide groove 218 is referred to as a retracting portion 218A. The role of the evacuation unit 218A will be described in detail later.

  The link gear guide groove 214 is positioned below the first post guide groove 218 and has an arc shape extending in the front-rear direction along the first post guide groove 218. The link gear guide groove 214 is longer than the first post guide groove 218, the front end is located in front of the front end of the first post guide groove 218, and the rear end is behind the first post guide groove 218. Located behind the edge. Further, below the link gear guide groove 214, a drive motor 210, a first gear 211, and a second gear 212 are provided side by side in the front-rear direction.

  The link gear 213 is provided with columnar projections 213A on the front side and the rear side of one side surface in the left-right direction, and the projections 213A are fitted into the link gear guide grooves 214, thereby It is supported by the side frame 40S so as to be movable in the front-rear direction along the gear guide groove 214. The link gear 213 is a rack having teeth on the lower surface, and is connected to a second gear 212 as a pinion positioned below the link gear 213 to form a rack and pinion.

  Further, a plate-like detector 213B protruding forward is provided at the front end of the link gear 213. The detector 213B is a member that turns on the lock detection sensor 221. On the other hand, the lock detection sensor 221 is, for example, a photoelectric sensor, and includes a light emitting unit and a light receiving unit (not shown in the figure) that are arranged to face each other in the vertical direction. The lock detection sensor 221 is provided in front of the link gear guide groove 214, and when the shutter 31 is normally locked, the detector 213B of the link gear 213 is positioned between the light emitting unit and the light receiving unit. ing. Note that how the shutter 31 is locked will be described later.

  The first link 215 is rotatably supported by a protrusion 213 </ b> A on the rear side of the link gear 213 with one end portion in the longitudinal direction in a direction in which the thickness direction is the left-right direction. Further, the other end portion in the longitudinal direction of the first link 215 and the one end portion in the longitudinal direction of the second link 216 are connected in a rotatable manner via the first post 217 so as to overlap in the left-right direction. Yes. The first post 217 is fitted in the first post guide groove 218. The diameter of the first post 217 is substantially the same as the width (length in the vertical direction) of the first post guide groove 218.

  Further, the other end portion in the longitudinal direction of the second link 216 is rotatably connected to the shutter 31 via the second post 219. The second post 219 is attached to the front end side of the rear projection 31B provided on one side surface of the shutter 31, and is formed by the second half portion of the guide groove 41 and the second post guide groove 220. The protrusion 31B on the rear side of the shutter 31 and the second post 219 are fitted in the hole. The diameter of the second post 219 is substantially the same as the width of the second post guide groove 220. As described above, the link gear 213 and the shutter 31 are connected via the first link 215 and the second link 216. The configuration of the shutter mechanism 200 is as described above.

  Here, the closing operation of the shutter 31 by the shutter mechanism 200 will be briefly described. As shown in FIGS. 14B and 15B, when the shutter 31 is in the open state, the shutter mechanism 200 has the link gear 213 positioned behind the link gear guide groove 214 and the first The link 215 and the second link 216 are in the shape of a letter that opens backward. Here, when the drive motor 210 is rotated in the direction of moving the link gear 213 forward by the control of the bill control unit 27, the link gear 213 starts moving forward. At this time, as the link gear 213 starts moving, the first link 215 and the second link 216 start moving forward while maintaining the shape of a dogleg. Then, as the first link 215 and the second link 216 start moving, the shutter 31 starts moving in the shutter closing direction (forward).

  Thereafter, as shown in FIG. 16A, the shutter 31 moves in the shutter closing direction as the link gear 213 moves forward. Then, as shown in FIG. 16B, when the second post 219 connecting the shutter 31 and the second link 216 moves to the front end of the second post guide groove 220, at this time, The shutter 31 is in a closed state (FIG. 14A) in which the claw portion 31C enters the groove 45 of the shutter facing portion 44 by a distance Y. At this time, the first post 217 connecting the first link 215 and the second link 216 is located directly below the retracting portion 218A of the first post guide groove 218.

  Even after the shutter 31 is closed, the link gear 213 moves forward. At this time, as shown in FIG. 16C, the second post 219 abuts against the front end of the second post guide groove 220 and cannot move further forward. The first post 217 also contacts the front end of the first post guide groove 218 and cannot move forward any more, but can move toward the retracting portion 218A. Therefore, when the link gear 213 further moves forward after the shutter 31 is closed, one end portion of the first link 215 is pulled forward by the link gear 213, so that the first link 215 and the second link 215 The link 216 is movable so as to increase the opening of the character. At this time, the second link 216 rotates about the second post 219 in the counterclockwise direction in the drawing, so that the first post 217 enters the retracting portion 218A of the first post guide groove 218.

  As described above, when the first post 217 enters the retracting portion 218A, the second link 216 cannot move forward or backward. As a result, the shutter 31 connected to the second link 216 is moved. It is locked because it cannot move in either the closing or opening direction. That is, at this time, the shutter 31 is closed and locked.

  Further, as shown in FIG. 16D, the link gear 213 stops moving under the control of the banknote control unit 27 after the first post 217 has advanced by a predetermined amount with the retraction unit 218A still entering. . At this time, the link gear 213 stops at a position where the front end of the detector 213B blocks the optical axis (not shown) of the lock detection sensor 221. Thereby, the lock detection sensor 221 is turned on. The closing operation of the shutter 31 by the shutter mechanism 200 is as described above.

  By the way, it is assumed that the elongated foreign object 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44 of the front frame 40F. At this time, as shown in FIG. 17A, depending on the thickness and material of the foreign matter 50, the claw portion 31C of the shutter 31 enters the groove 45 of the shutter facing portion 44, and the shutter 31 is not completely closed. There is a case where the detector 31E of the shutter 31 reaches the shutter close sensor 43 and the shutter close sensor 43 is turned on, although the claw portion 31C does not enter the groove 45 by the distance Y.

  On the other hand, the shutter mechanism 200 cannot move the first post 217 of the opening / closing lock mechanism 201 to the retracting portion 218A and lock the shutter 31 until the shutter 31 is completely closed. That is, in the shutter mechanism 200, even if the shutter closing sensor 43 is on, the lock detection sensor 221 is not turned on unless the shutter 31 is completely closed.

  Therefore, in the shutter mechanism 200, as shown in FIGS. 17A and 17B, the claw portion 31C of the shutter 31 enters the groove 45 of the shutter facing portion 44 while the foreign object 50 is sandwiched, so that the shutter 31 is completely Even when the shutter closing sensor 43 is turned on although it is not closed, the lock detection sensor 221 is not turned on so that the foreign object 50 can be detected. In other words, the shutter mechanism 200 can detect the pinching of the foreign object 50 more reliably than the shutter mechanism 32 having only the shutter closing sensor 43.

[3-2. Functional configuration of automatic teller machine]
Next, the functional configuration of the automatic teller machine 1 according to the third embodiment will be described with reference to the block diagram shown in FIG. FIG. 18 is a block diagram corresponding to FIG. 7, and the same portions are denoted by the same reference numerals and description thereof is omitted as appropriate.

  As shown in FIG. 18, the shutter control unit 52 includes an instruction from the main control unit 9, a detection result of the hand shear detection sensor 42, a detection result of the shutter close sensor 43, and a detection result of the lock detection sensor 221. At the same time, the drive motor 210 is controlled to control the opening and closing of the shutter 31. The functional configuration of the automatic teller machine 1 is as described above.

[3-3. Shutter closing process]
Next, the procedure of the shutter closing process according to the third embodiment will be described with reference to the flowchart shown in FIG. FIG. 19 is a flowchart corresponding to FIG. 8, and the same reference numerals are given to the same steps. That is, the shutter closing process according to the third embodiment is obtained by adding the process of step SP10 between steps SP6 and SP7 of the shutter closing process according to the first embodiment. Therefore, here, the process of step SP10 will be described. In this shutter closing process, the shutter control unit 52 counts the number of pulses included in the pulse signal that drives the drive motor 210, and the shutter 31 and the link gear estimated based on the number of pulses. The positions of the shutter 31 and the link gear 213 are monitored from the movement amount of 213.

  In step SP6, the shutter controller 52 determines whether the shutter closing sensor 43 is turned on until the amount of movement of the shutter 31 based on the number of pulses of the drive motor 210 reaches a predetermined amount required for the shutter 31 to be closed. If the shutter closing sensor 43 is on, an affirmative result is obtained in step SP5, and the process proceeds to step SP10.

  In step SP10, the shutter control unit 52 determines whether or not the lock detection sensor 221 is turned on until the amount of movement of the link gear 213 based on the number of pulses reaches a predetermined amount required for the shutter 31 to be locked. .

  Here, if the lock detection sensor 221 is turned on before the amount of movement of the link gear 213 based on the number of pulses reaches a predetermined amount required for the shutter 31 to be locked, this means that the shutter 31 is locked. Means that In this case, the shutter control unit 52 obtains a positive result in step SP10, moves to step SP7, ends the closing operation of the shutter 31, and ends a series of shutter closing processes.

  On the other hand, if the lock detection sensor 221 is not turned on before the amount of movement of the link gear 213 based on the number of pulses reaches a predetermined amount required for the shutter 31 to be locked, this is, for example, shown in FIG. As shown in (A) and (B), the shutter closing sensor 43 is on, but the shutter 31 is not completely closed due to a foreign object 50 being caught.

  In this case, the shutter control unit 52 obtains a negative result in step SP10, and proceeds to step SP3. In step SP3, the shutter control unit 52 interrupts the closing operation of the shutter 31 and executes the opening operation of the shutter 31, thereby opening the shutter 31 to the open state (or halfway). By doing so, the shutter control unit 52 allows the customer to recognize that the shutter 31 cannot be closed normally, and removes the foreign matter 50 entering the banknote storage unit 30, for example. Thereafter, the shutter control unit 52 returns to step SP1 and starts the closing operation of the shutter 31 again. At this time, the pulse count is once reset. The procedure of the shutter closing process is as described above. Also in this case, the time from the start of the closing operation of the shutter 31 is counted, and the shutter closing sensor 43 and the lock detection sensor 221 are turned on until a predetermined time required until the shutter 31 is locked. You may check if it is.

[3-4. Summary and Effect]
As described so far, in the third embodiment, the shutter mechanism 200 is locked with the opening / closing lock mechanism 201 that locks the movement of the shutter 31 in the opening / closing direction after the shutter 31 is closed. A lock detection sensor 221 for detecting whether or not is provided. The open / close lock mechanism 201 is configured such that the shutter 31 cannot be locked unless the shutter 31 is completely closed, and the lock detection sensor 221 is turned on when the shutter 31 is completely closed and the shutter 31 is locked. I did it.

  In this way, in the shutter mechanism 200, for example, the thin foreign object 50 that is easily deformed is sandwiched between the shutter 31 and the shutter facing portion 44, and the claw portion 31 </ b> C of the shutter 31 enters the groove 45 of the shutter facing portion 44. Even when the shutter 31 is not completely closed but the shutter closing sensor 43 is turned on, the lock detection sensor 221 is not turned on at this time, thereby detecting that the foreign object 50 is caught. it can. That is, the shutter mechanism 200 can detect the pinching of the foreign object 50 more reliably than the case where the shutter closing sensor 43 alone detects the pinching of the foreign object 50.

  Further, in this shutter mechanism 200, the shutter close sensor 43 and the lock detection sensor 221 detect the foreign object 50 being sandwiched, and the shutter 31 is sandwiched between the shutter 31 and the shutter facing portion 44 at the front end portion of the shutter 31. It is possible to detect that the foreign matter 50 is sandwiched between the front end portion of the shutter 31 and the shutter facing portion 44 without providing a dedicated foreign matter detection sensor for detecting the foreign matter.

  According to the above configuration, the automatic teller machine 1 and the banknote depositing / dispensing machine 10 having the shutter mechanism 200 have a simpler configuration as compared with the related art, but the foreign object 50 is between the shutter 31 and the shutter facing portion 44. It is possible to detect the pinching more reliably.
