Title: Medium processing device

Description:
TECHNICAL FIELD 
     The present application claims priority over Japanese Patent Application No. 2011-252916, filed on Nov. 18, 2011, the disclosure of which is incorporated herein by reference in its entirety. 
     The present invention relates to a medium processing device, and particularly relates to an automatic teller machine (ATM) or the like, into which a medium such as, for example, banknotes is deposited and that conducts desired transactions. 
     BACKGROUND ART 
     Heretofore, an ATM or the like that is used in financial institutions is configured such that, in accordance with the details of a transaction with a customer, cash—for example, banknotes and coins—is deposited by the customer or cash is withdrawn by the customer. 
     An ATM has been proposed (for example, see  FIG. 1  of Japanese Patent No. 3,207,504) that includes: a banknote input/output port for transferring banknotes to and from, for example, customers; a verification section that verifies the denominations of deposited banknotes and whether the banknotes are authentic; a temporary holding section that temporarily retains the deposited banknotes; and denomination cassettes that store the banknotes of the respective denominations. 
     In a deposit transaction, when a customer deposits banknotes in the banknote input/output port, this ATM verifies the deposited banknotes at the verification section, and retains banknotes that are verified as being authentic in the temporary holding section. Meanwhile, banknotes that are verified as not being suitable for the transaction are returned to the banknote input/output port and returned to the customer. Then, when the customer has confirmed a deposit amount, the ATM re-verifies the denominations of the banknotes retained in the temporary holding section at the verification section, and stores the banknotes in the denomination cassettes in accordance with the verified denominations. 
     Among ATMs, there is an ATM with a structure in which the temporary holding section can be withdrawn from the main body of the ATM, so as to improve the work efficiency of maintenance operations. 
     For example, as illustrated in  FIG. 16A , in an ATM  200 , a frame  20  of a temporary holding section  215  is mounted at a main body frame  211 F. The interior of the main body frame  211 F is structured such that banknotes are transferred between a conveyance section  13  that conveys the banknotes and a transfer aperture  23  of the temporary holding section  215 . 
     At the ATM  200 , as illustrated in  FIG. 16B , a portion of the conveyance section  13 , the transfer aperture  23  of the temporary holding section  215  and suchlike are exposed to the exterior during maintenance operations, by the frame  20  of the temporary holding section  215  being turned about a turning shaft  22 . Thus, the efficiency of maintenance operations may be improved. 
     Hereinafter, a state in which the temporary holding section  215  is mounted to the main body frame  211 F and banknotes BL can be transferred ( FIG. 16A ) is referred to as “the mounted state”, and a state in which the temporary holding section  215  is turned and removed from the main body frame  211 F to expose the transfer aperture  23  and the like ( FIG. 16B ) is referred to as “the detached state”. 
     When the temporary holding section  215  receives a banknote from the main body frame  211 F side, conveyance rollers  24  and the like are rotated and the banknote is conveyed along a conveyance path  26 , and is wound onto a periphery side face of a drum  27  with a tape, which is not illustrated in the drawings. 
     An operation knob  221  for maintenance operations is provided at the temporary holding section  215 . A gear, which is not illustrated in the drawings, is provided at the operation knob  221 . The temporary holding section  215  is structured such that, when the gear is pushed in into the frame  20 , the gear temporarily meshes with another gear or the like inside the temporary holding section  215 , and the drum  27 , the conveyance rollers  24  and the like (shown by broken lines in the drawings) inside the temporary holding section  215  may be operated by hand. 
     SUMMARY OF INVENTION 
     Technical Problem 
     In this temporary holding section  215 , if the operation knob  221  is rotated in a predetermined direction in the state in which a banknote is wound onto the drum  27  during maintenance operations, the banknote is conveyed along the conveyance path  26  to the transfer aperture  23 . 
     If the temporary holding section  215  is in the detached state ( FIG. 16B ) at this time, the banknote may be fed out from the transfer aperture  23 , and this banknote may be retrieved by a maintenance technician or the like. 
     On the other hand, if the temporary holding section  215  is in the mounted state ( FIG. 16A ), because the conveyance section  13  in the main body frame  211 F is not operating, the banknote reaching the transfer aperture  23  may not be fed out and may become jammed in the conveyance path  26  or the like. 
     When this happens, as illustrated in  FIG. 17 , banknotes may be successively jammed in the conveyance path  26  of the temporary holding section  215 , and there is a risk of damage to the mechanisms, tape (not illustrated in the drawings) and the like in the temporary holding section  215 , and also of damage to the banknotes. 
     Thus, in the ATM  200 , if the operation knob  221  is operated in the state in which the temporary holding section  215  is mounted to the main body frame  211 F, banknotes may become jammed in the conveyance path  26  and the like inside the temporary holding section  215 , or mechanisms, banknotes and the like may be damaged. 
     The present invention has been made in consideration of the problem described above, and a medium processing device that may prevent damage to the device and the medium during maintenance operations is proposed. 
     Solution to Problem 
     A present aspect of the medium processing device for solving this problem is provided with: a temporary holding section that temporarily retains a medium therein; a gear that is provided inside the temporary holding section, and that drives a mechanism that stores the medium into the temporary holding section and feeds out the medium from inside the temporary holding section; a main body that includes a mounting location at which the temporary holding section is mounted, and that transfers the medium to and from the temporary holding section at a time at which the temporary holding section is mounted at the mounting location; an operation knob that transmits, to the gear, a rotary operation applied from outside of the temporary holding section; and an operation restriction portion that is provided at the main body, that blocks transmission of the rotary operation from the operation knob to the gear in a mounted state in which the temporary holding section is mounted at the mounting location of the main body, and that allows transmission of the rotary operation from the operation knob to the gear in a detached state in which the temporary holding section is detached from the mounting location. 
     Thus, the transmission of rotation from the operation knob to the gear may be blocked by the operation restriction portion when the temporary holding section is in the mounted state, whereas a rotation may be transmitted from the operation knob to the gear when the temporary holding section is in the detached state, and the gear may be driven via the operation knob. 
     In the present aspect, the operation knob includes a gearwheel, the gearwheel of the operation knob meshing with the gear by being moved to a predetermined meshing position, and the meshing with the gear being released by the operation knob being moved to a withdrawn position that is distant from the meshing position; and the operation restriction portion blocks the transmission of the rotary operation from the operation knob to the gear in the mounted state by keeping the operation knob at the withdrawn position, and allows movement of the operation knob to the meshing position in the detached state. 
     In the present aspect, the operation restriction portion may keep the operation knob at the withdrawn position in the mounted state by engaging with the operation knob. 
     In the present aspect, the operation restriction portion may keep the operation knob at the withdrawn position in the mounted state by covering the operation knob and preventing operation of the operation knob from outside. 
     In the present aspect, the operation restriction portion may keep the operation knob at the withdrawn position in the mounted state by being disposed between the withdrawn position and the meshing position of the operation knob. 
     In the present aspect, in the mounted state, the operation restriction portion may engage with the operation knob at plural locations around a rotation axis of the operation knob. 
     In the present aspect, the temporary holding section includes: a drum, on a peripheral face of which the medium is wound; and a conveyance section that conveys the medium between the drum and the main body, the gear includes: a drum gear that transmits driving force from a predetermined drum motor to the drum; and a conveyance gear that transmits driving force from a predetermined conveyance motor to the conveyance section without transmitting driving force from the drum motor, during non-operation of the operation knob while the rotary operation is not being applied from outside the temporary holding section, the operation knob does not transmit the rotary operation to the drum gear and/or the conveyance gear, and, during operation of the operation knob while the rotary operation is being applied from outside the temporary holding section, the operation knob transmits rotary operation to both the drum gear and the conveyance gear. 
     Effects of Invention 
     According to the present aspect, when the temporary holding section is in the mounted state, the transmission of rotation from the operation knob to the gear may be blocked by the operation restriction portion, whereas when the temporary holding section is in the detached state, rotation may be transmitted from the operation knob to the gear and the gear may be driven via the operation knob. Thus, according to the present aspect, a medium processing device that may prevent damage to the device and the medium during maintenance operations may be embodied.

     DESCRIPTION OF EMBODIMENTS 
     Herebelow, embodiments for implementing the invention (referred to as embodiments hereinafter) are described using the attached drawings. 
     1. First Embodiment  
     1-1. Overall Structure of Automatic Teller Machine 
     As the external appearance is illustrated in  FIG. 1 , an ATM  1  is basically structured by a box-shaped casing  2 , and is configured to conduct transactions relating to cash with customers. 
     The casing  2  is provided with a customer service section  3  at a location at which insertions of banknotes, operations of a touch panel are easy in a state in which a customer is stood at the side of a front face  2 A of the casing  2 . That is, the customer service section  3  is provided at a portion extending from an upper portion of the front face  2 A to an upper face of the casing  2 . 
     The customer service section  3  is configured to implement direct transfers of cash, bank books and the like to and from customers, and to give notification of information relating to transactions, accept operational instructions. The customer service section  3  is provided with a coin input/output port  4 , a banknote input/output port  5 , a bank book insertion port  6 , a card insertion port  7 , and a display/operation section  8 . 
     The coin input/output port  4  and the banknote input/output port  5  are section into which coins and banknotes BL that customers are depositing are respectively input, and from which coins and banknotes BL that customers are withdrawing are respectively fed out. The coin input/output port  4  and the banknote input/output port  5  are opened and closed by driving respective shutters provided thereat. The banknotes BL are formed as, for example, rectangular pieces of paper. 
     The bank book insertion port  6  is a section into which bank books that are to be used in transactions are inserted and from which the bank books are fed out when transactions are finished. A bank book processing section (not illustrates in the drawings) that records transaction details and the like in bank books is provided behind the bank book insertion port  6 . 
     The card insertion port  7  is a section into which various kinds of cards such as cash cards are inserted and from which the cards are fed out. A card processing section (not illustrated in the drawings) that reads magnetically recorded account numbers and the like on the various cards is provided behind the card insertion port  7 . 
     In the display/operation section  8  a liquid crystal display (LCD), which displays operation screens during transactions, is integrated with a touch panel, at which selections of types of transaction, PIN numbers, transaction amounts and the like are entered. 
     The casing  2  is structured with doors that are capable of opening and closing portions of side faces such as the front face  2 A or the opposite side face of the front face  2 A (that is, a rear face side). That is, during transaction operations in which the ATM  1  is conducting transactions relating to cash with customers, the casing  2  protects banknotes BL, coins retained therein by the doors being closed. During maintenance operations in which technicians are conducting maintenance operations, operations of the respective sections inside the casing  2  may be performed easily by the doors being opened as necessary. 
     Hereinafter, descriptions are given by defining the front face  2 A side of the ATM  1  as a front side, the opposite side as a rear side, the left and right as viewed by a customer standing at the front face  2 A side of the ATM  1  as a left side and right side, and by defining an upper side and lower side. 
       FIG. 2  is a side view in which the ATM  1  of  FIG. 1  is viewed from the left side.  FIG. 2  illustrates portions of internal structures of the ATM  1  that principally relate to the processing of banknotes. As illustrated in  FIG. 2 , a banknote processing section  11  that performs various kinds of processing of banknotes BL is provided at the upper side of the interior of the ATM  1 , and a banknote storage section  12  that stores the banknotes BL is provided at the lower side of the interior of the ATM  1 . 
     The banknote input/output port  5  that is a portion of the customer service section  3 ; a verification section  14  that verifies denominations, authenticity and the like of the banknotes BL; a temporary holding section  15  that temporarily retains deposited banknotes; and so forth are provided inside the banknote processing section  11 . 
     A conveyance section  13  is provided inside the banknote processing section  11 , which conveys the banknotes BL along a predetermined conveyance path (shown by heavy lines in the drawing) between the respective sections of the banknote processing section  11 , with a short side direction of the banknotes BL oriented in the traveling direction. 
     Banknote storages  17  that separately store the banknotes BL by the denominations, and a reject storage  18  that stores banknotes BL that have been verified as not being suitable for distribution due to damage or the like, are provided in the banknote storage section  12 . 
     The ATM  1  is collectively controlled as a whole by a control section  10 . When, for example, a customer is performing a deposit transaction to deposit banknotes BL, the control section  10  receives predetermined operational inputs via the display/operation section  8  ( FIG. 1 ), after which the ATM  1  opens the shutter of the banknote input/output port  5  and the banknotes BL are deposited therein. 
     Then, the control section  10  conveys the deposited banknotes BL to the verification section  14  via the conveyance section  13 , and the verification section  14  verifies the banknotes BL. Banknotes BL that are verified as being proper banknotes are conveyed to the temporary holding section  15  and temporarily retained thereat, whereas banknotes BL that are verified as being unsuitable for the transaction are conveyed to the banknote input/output port  5  and returned to the customer. 
     The control section  10 A confirms a deposit amount with the customer via the display/operation section  8 , and conveys the banknotes BL retained at the temporary holding section  15  back to the verification section  14  to re-verify the denominations thereof, and then conveys the banknotes BL to the banknote storage section  12 . 
     The banknote storage section  12  conveys banknotes BL that are identified by the verification section  14  as being undamaged to the respective banknote storages  17  corresponding to the denominations thereof, and stores these banknotes BL therein. The banknote storage section  12  also conveys banknotes BL that are identified by the verification section  14  as being damaged to the reject storage  18  and stores these banknotes BL therein. 
     1-2. Structure of the Temporary Holding Section 
     As illustrated in a side view in  FIG. 3 , the temporary holding section  15  is structured by respective members that are disposed inside the frame  20 , which forms an outer shell of the temporary holding section  15 . An operation knob  21  is exposed through a hole portion  20 H that is formed in a left side face of the frame  20 . 
     When the temporary holding section  15  receives a banknote BL from the conveyance section  13  of the banknote processing section  11  ( FIG. 2 ) via the transfer aperture  23 , the banknote BL is caused to travel rearward along a conveyance path  26  by conveyance rollers  24  rotating in the direction of arrow S 1 , driven rollers  25  rotating in the direction of arrow T 1  to follow the rotation of the conveyance rollers  24 , and the like. 
     The temporary holding section  15  is configured to successively store the banknotes BL by rotating a drum  27 , which has a cylindrical shape, in the direction of arrow R 1  and winding the banknotes BL onto the outer periphery of the drum  27  together with a tape (not illustrated in the drawings). 
     When the temporary holding section  15  receives an instruction from the control section  10  ( FIG. 2 ) to feed out a banknote BL, the temporary holding section  15  unwinds the banknote BL that has been wound onto the periphery face of the drum  27 , together with the tape, by rotating the drum  27  in the direction of arrow R 2 , and transfers the banknote BL to the conveyance path  26 . 
     Then, the temporary holding section  15  causes the banknote BL to travel in the forward direction along the conveyance path  26  by rotating the conveyance rollers  24  and the driven rollers  25  in the directions of arrows S 2  and T 2 , respectively, and transfers the banknote BL through the transfer aperture  23  to the conveyance section  13  of the banknote processing section  11 . 
     The temporary holding section  15  is configured to be capable of turning about a turning shaft  22  ( FIG. 3 ), which is arranged along the left-right direction, in the direction of arrow U 1  or in the direction of arrow U 2  relative to a banknote processing section frame  11 F ( FIG. 2 ) of the banknote processing section  11 . 
     That is, similarly to the conventional temporary holding section  215 , the temporary holding section  15  may be switched between the mounted state ( FIG. 16A ), in which the temporary holding section  15  is mounted at the banknote processing section frame  11 F, and the detached state ( FIG. 16B ), in which the temporary holding section  15  is removed from the banknote processing section frame  11 F, by being turned about the turning shaft  22 . 
     As illustrated in the schematic perspective view in  FIG. 4 , in addition to the above-mentioned drum  27 , conveyance rollers  24 , a motor as a power source, gearwheels for transmitting driving force and the like are provided inside the temporary holding section  15 . 
     A motor  31  rotates in accordance with control from the control section  10  ( FIG. 2 ). A gear  32  is mounted to an output shaft of the motor  31 . The gear  32  meshes with a gear  33 , which is mounted to a rotation axle of the drum  27 . 
     According to this structure, the temporary holding section  15  is configured such that, when the motor  31  rotates, rotary driving force is transmitted to the drum  27  via the gear  32  and the gear  33 , and the drum  27  is rotated. 
     A motor  34  rotates in accordance with control from the control section  10  ( FIG. 2 ). A gear  35  is mounted to an output shaft of the motor  34 . The gear  35  meshes with a gear  36 , which is mounted to a rotation axle of the conveyance rollers  24 . 
     According to this structure, the temporary holding section  15  is configured such that, when the motor  34  rotates, rotary driving force is transmitted to the conveyance rollers  24  via the gear  35  and the gear  36 , and the conveyance rollers  24  and the driven rollers  25  are rotated. 
     In the temporary holding section  15 , the drum driving system that transmits driving force from the motor  31  to the drum  27  is separate from the conveyance driving system that transmits driving force from the motor  34  to the conveyance rollers  24 , and these systems may be operated respectively independently from one another. 
     As illustrated in  FIG. 4 , the operation knob  21  has a form in which plural cylindrical members, gears and the like are layered in the left-right direction. 
     As illustrated in a plan view in  FIG. 5A , the operation knob  21  is generally formed in a circular rod shape, with a central axis along the left-right direction. A slot portion  21 R that is constricted to be narrow is formed at an approximately central portion of the operation knob  21  in the left-right direction. A gear portion  21 C, which is a spur gear, is mounted at the right end of the operation knob  21  so as to be coaxial with the central axis. 
     A grip that enables easy gripping with the fingertips is formed by a left side face of the circular rod-shaped portion of the operation knob  21  being indented into a predetermined shape. 
     The operation knob  21  is mounted to a shaft  28  so as to be coaxial therewith, and may freely rotate about the shaft  28  serving as a rotation axis. 
     The shaft  28  includes a compression mechanism, which is not illustrated in the drawings. By the overall length of the shaft  28  being compressed, the operation knob  21  may be moved in the left-right direction within a predetermined movement range. A spring  29 , which is a coil spring, is fitted around the shaft  28  in a state in which the spring  29  is compressed from the natural length thereof. 
     According to this structure, in a state in which no external force is applied, such as during usual operation in which usual transaction processing is being performed at the ATM  1 , the operation knob  21  is urged leftward by urging force of the spring  29  and, as illustrated in  FIG. 5A , the operation knob  21  is in a state that is moved furthest to the left. 
     In this state, a large portion of the operation knob  21  including the slot portion  21 R protrudes to the left side relative to the frame  20 , that is, protrudes to the outer side of the frame  20 , and the gear portion  21 C does not mesh with either of the gears but is withdrawn and is in a free state. Hereinafter, the position of the operation knob  21  in this state is referred to as “the withdrawn position”. 
     On the other hand, when an external force is applied to the operation knob  21 , such as being pushed in the rightward direction, the operation knob  21  moves rightward while compressing the spring  29  and, as illustrated in  FIG. 5B , goes to a state in which the operation knob  21  is moved furthest to the right. 
     In this state, a large portion of the operation knob  21  including the slot portion  21 R is depressed to the right side relative to the frame  20 , that is, to the inner side of the frame  20 , and the gear portion  21 C is in a state of being meshed with both the gear  32  and the gear  35 . Hereinafter, the position of the operation knob  21  in this state is referred to as “the meshing position”. 
     Hence, if the operation knob  21  is rotated in either direction at the meshing position, the driving force of the rotation may be transmitted to both of the gears  32  and  35 , and both the drum  27  and the conveyance rollers  24  and driven rollers  25  may be rotated simultaneously. 
     In practice, in a state of the temporary holding section  15  in which banknotes BL have been wound onto the periphery face of the drum  27 , if the operation knob  21  is put into the depressed state by an operation by a maintenance technician and rotated in a predetermined direction, the drum  27 , the conveyance rollers  24  and the driven rollers  25  are simultaneously rotated in the directions of arrow R 2 , arrow S 2  and arrow T 2 , respectively, and the banknotes BL may be fed out through the transfer aperture  23 . 
     From the depressed state, when the external force to rightward is released, the operation knob  21  is moved in the leftward direction by restoring force of the spring  29 , and returns to the protruding state ( FIG. 5A ). 
     Thus, the temporary holding section  15  is structured such that, during usual operations, the operation knob  21  is retained at the withdrawn position and the gear portion  21 C is unmeshed. On the other hand, during maintenance operations, if the operation knob  21  is pushed into the meshing position, the gear portion  21 C meshes with the gears  32  and  35 , and a rotary driving force from the operation knob  21  may be transmitted thereto. 
     1-3. Structure of the Operation Restriction Plate 
     At the banknote processing section  11  ( FIG. 2 ), an operation restriction plate  41  is mounted as illustrated in  FIG. 6 . 
     The operation restriction plate  41  is structured by a thick metal plate being bent into a backward “L”-shape as viewed from the rear side. The operation restriction plate  41  is fixed to an upper face at the rear left of the banknote processing section frame  11 F that forms the outer shell of the banknote processing section  11 , by being screwed thereto. 
     A cutout portion  41 X is formed, by being cut away in a substantial “U”-shape as viewed in the left-right direction, at a vicinity of a front-rear direction central portion of an upper edge of the operation restriction plate  41 . An upper portion of the cutout portion  41 X is rectangular and a lower portion of the cutout portion  41 X is semi-circular. 
     The diameter of the semi-circle forming the lower portion of the cutout portion  41 X, which is the width of the upper portion in the front-rear direction, is smaller than the diameter of the circular rod-shaped portions of the operation knob  21  but is slightly larger than the diameter of the slot portion  21 R. 
     As illustrated in  FIG. 7 , the operation restriction plate  41  meshes with the slot portion  21 R formed at the operation knob  21  of the temporary holding section  15  when the temporary holding section  15  is in the mounted state. 
     At the operation restriction plate  41  in this state, as illustrated in  FIG. 8A  and  FIG. 9 , the cutout portion  41 X is fitted around the slot portion  21 R of the operation knob  21  and the slot portion  21 R is engaged with the lowest side of the cutout portion  41 X, including a portion that may be referred to as “the bottom” of the cutout portion  41 X. 
     Thus, the operation restriction plate  41  impedes movement of the operation knob  21  in the rightward direction, and keeps the operation knob  21  at the withdrawn position, that is a position at which the gear portion  21 C does not mesh with either of the gears  32  and  35 . 
     On the other hand, when the temporary holding section  15  is turned from the mounted state in the direction of arrow U 1  ( FIG. 3 ) to the detached state, as illustrated in  FIG. 8B , the engagement between the cutout portion  41 X of the operation restriction plate  41  and the slot portion  21 R of the operation knob  21  is released. 
     In this state, movement of the operation knob  21  in the rightward direction is possible. Therefore, if an external force to the rightward is applied, the operation knob  21  moves to the meshing position and, as illustrated in  FIG. 5B , the gear portion  21 C may be meshed with the gear  32  and the gear  35 . 
     When the temporary holding section  15  is turned back from the detached state in the direction of arrow U 2  ( FIG. 3 ) to the mounted position, the cutout portion  41 X of the operation restriction plate  41  is again engaged with the slot portion  21 R of the operation knob  21 . Thus, movement of the operation knob  21  to the rightward is again impeded and the operation knob  21  is kept at the withdrawn position. 
     Thus, the operation restriction plate  41  keeps the operation knob  21  at the withdrawn position and impede meshing between the gear portion  21 C and the gears  32  and  35 , by the cutout portion  41 X engaging with the slot portion  21 R of the operation knob  21 , only when the temporary holding section  15  is in the mounted state. 
     1-4. Operation and Effects 
     In the structure described above, the banknote processing section  11  of the ATM  1  according to the first embodiment is configured such that the temporary holding section  15  is turnable relative to the banknote processing section frame  11 F, and the slot portion  21 R is formed in the operation knob  21 . 
     In the temporary holding section  15 , the operation knob  21  is movable between the withdrawn position and the meshing position. The gear portion  21 C of the operation knob  21  is not meshed with anything at the withdrawn position, but is meshed with the gear  32  and the gear  35  at the meshing position. 
     Meanwhile, the operation restriction plate  41  in which the U-shaped cutout portion  41 X is formed is provided at the banknote processing section frame  11 F. When the temporary holding section  15  is in the mounted state and the transfer aperture  23  is close to the conveyance section  13  of the banknote processing section  11 , the cutout portion  41 X of the operation restriction plate  41  is engaged with the slot portion  21 R of the operation knob  21  ( FIG. 7 ,  FIG. 8A  and  FIG. 9 ). 
     When, for example, a maintenance operation is being carried out at the ATM  1 , the banknote processing section frame  11 F is pulled out to rearward from the casing  2  by an operation of a maintenance technician. At this stage, the temporary holding section  15  is in the mounted state, and the slot portion  21 R of the operation knob  21  is engaged with the cutout portion  41 X of the operation restriction plate  41 . 
     Therefore, even if an external force in the rightward direction is applied to the operation knob  21  by the maintenance technician, the operation knob  21  may be kept at the withdrawn position ( FIG. 5A ), and the gear portion  21 C does not mesh with the gears  32  and  35 . 
     Thus, the drum  27 , the conveyance rollers  24  and the like inside the temporary holding section  15  are not rotated while the temporary holding section  15  is in the mounted state. Therefore, even if banknotes BL are being stored inside the temporary holding section  15 , these banknotes BL will not be conveyed. 
     As a result, situations such as banknotes BL moving to be fed out from the transfer aperture  23  and getting jammed in the conveyance path  26 , the drum  27  and tape (not illustrated in the drawings) or the like being damaged by jammed banknotes BL, the jammed banknotes BL themselves being damaged, and so forth may be pre-emptively prevented in the temporary holding section  15 . 
     Because the operation restriction plate  41  is structured by a thick metal plate, even if the maintenance technician forcibly or accidentally applies an external force, there is little danger of the operation restriction plate  41  being deformed or broken, and the operation knob  21  may continue to be kept at the withdrawn position. 
     Because the cutout portion  41 X of the operation restriction plate  41  is formed in a U-shape that is deeper than a semi-circle, the slot portion  21 R may be engaged over a wide range that extends to a portion at the upper side relative to the rotation axis of the operation knob  21  (marked as point P in  FIG. 8A ). 
     Therefore, the operation restriction plate  41  may engage the slot portion  21 R from both the front and rear sides, around the rotation axis of the operation knob  21 . Thus, the risk of this engagement being easily released due to problems such as positional inaccuracy (due to “looseness” or the like) may be reduced. 
     Moreover, the likelihood of the cutout portion  41 X being capable of engaging with the slot portion  21 R of the operation knob  21  may be improved, even if the operation restriction plate  41  is lifted in the upward direction to some extent relative to the banknote processing section frame  11 F when the temporary holding section  15  is in the mounted state, due to problems such as positional inaccuracy. 
     Since the operation restriction plate  41  has a relatively large area as viewed in the left-right direction, when the temporary holding section  15  is in the mounted state, the operation restriction plate  41  is disposed at the left side of the frame  20  and is substantially parallel, with a small gap, with a portion of the frame  20  that forms a left side plate ( FIG. 8A  and  FIG. 9 ). 
     Therefore, even if positional accuracy in the left-right direction between the temporary holding section  15  and the banknote processing section frame  11 F is poor and the gap between the temporary holding section  15  and the left side plate of the frame  20  is altered, the operation restriction plate  41  abuts against the left side plate of the frame  20 , and thus the portion of the operation restriction plate  41  at the left side relative to the slot portion  21 R of the operation knob  21  may be kept in a state of protruding to the left side from the frame  20 . 
     On the other hand, when the temporary holding section  15  is turned from the mounted state in the direction of arrow U 1  ( FIG. 3 ) to the detached state, the engagement between the slot portion  21 R of the operation knob  21  and the cutout portion  41 X of the operation restriction plate  41  may be released ( FIG. 8B ). 
     That is, simply by the temporary holding section  15  being turned by a maintenance technician in the same manner as in the conventional configuration, for purposes such as improving the efficiency of maintenance operations, exposing the transfer aperture  23  and a portion of the conveyance section  13  and so forth, the blocking of operations of the operation knob  21  may be released. 
     Thus, only in the detached state in which the transfer aperture  23  is separated from the conveyance section  13  of the banknote processing section  11  and the banknotes BL may be fed out, operation of the operation knob  21  of the temporary holding section  15  is allowed, the operation knob  21  may be moved to the meshing position, the gear portion  21  C may be meshed with the gears  32  and  35 , and the drum  27  and the conveyance rollers  24  and the like may be rotated. 
     In this state, because the gear portion  21 C of the operation knob  21  is meshed with both of the gears  32  and  35  that are basically driven independently from one another, rotary operations of the operation knob  21  may be transmitted to both the drum  27  and the conveyance rollers  24  and the like at the same time. 
     Thus, at the temporary holding section  15 , banknotes BL that are wound onto the drum  27  may be fed out just by, for example, a maintenance technician operating the operation knob  21  with one hand, and the maintenance technician may retrieve the banknotes BL with their other hand. 
     According to the structure described above, in the banknote processing section  11  of the ATM  1 , when the temporary holding section  15  is in the mounted state, the cutout portion  41 X of the operation restriction plate  41  is engaged with the slot portion  21 R of the operation knob  21  and is retained at the withdrawn position. Thus, the gear portion  21 C is not meshed with anything, and rotary operations of the drum  27 , the conveyance rollers  24  and the like may be restricted. On the other hand, when the temporary holding section  15  at the banknote processing section  11  is turned to the detached state, the engagement between the cutout portion  41 X of the operation restriction plate  41  and the slot portion  21 R of the operation knob  21  is released. Hence, the operation knob  21  of the temporary holding section  15  may be moved from the withdrawn position to the meshing position, the gear portion  21 C may be meshed with the gear  32  and the gear  35 , and rotary operations of the drum  27 , the conveyance rollers  24  and the like via the operation knob  21  may be enabled. 
     2. Second Embodiment 
     An ATM  101  according to a second embodiment differs from the ATM  1  according to the first embodiment ( FIG. 1  and  FIG. 2 ) in including a banknote processing section  111  instead of the banknote processing section  11 , but other portions have the same structures. 
     The banknote processing section  111  differs from the banknote processing section  11  according to the first embodiment in including a temporary holding section  115  and an operation restriction plate  141  instead of the temporary holding section  15  and the operation restriction plate  41 , but other portions have the same structures. 
     2-1. Structure of the Temporary Holding Section 
     The temporary holding section  115  differs from the temporary holding section  15  according to the first embodiment ( FIG. 3  to  FIG. 9 ) in including an operation knob  121  instead of the operation knob  21 , but other portions have the same structures. 
     As illustrated in  FIG. 10 ,  FIG. 11A  and  FIG. 11B , the operation knob  121  is structured with a first gear  121 A and a second gear  121 B. 
     The first gear  121 A has a structure in which a thin disc-shaped member and a spur gear are superposed such that central axes thereof are aligned with one another. The first gear  121 A is mounted to a shaft  128  so that the central axis is also aligned with the shaft  128 . A grip  121 AK is formed by a left face of the disc-shaped part of the first gear  121 A being indented into a predetermined shape. 
     As illustrated in  FIG. 12A , small square rod-shaped protrusions  121 AP protruding to the rightward are provided at a right side face of a gear part  121 AC of the first gear  121 A. The protrusions  121 AP are provided at two locations opposing one another from either side of the central axis of the first gear  121 A. 
     The second gear  121 B is a spur gear, as illustrated in  FIG. 11B , and is fitted around the shaft  128 . Hole portions  121 BH are bored at a left side face of the second gear  121 B, at positions respectively corresponding with the two protrusions  121 AP of the first gear  121 A. The hole portions  121 BH are square holes slightly larger than the protrusions  121 AP. 
     As illustrated in  FIG. 12A , the second gear  121 B is continuously meshed with the gear  32 . The gear  35  is disposed slightly left side relative to the second gear  121 B, such that the gear  35  does not mesh with the second gear  121 B. 
     The shaft  128  supports the second gear  121 B to be rotatable but not to move in the left-right direction. Meanwhile, the shaft  128  supports the first gear  121 A to be rotatable and, by a portion of the shaft  128  being compressed, movable rightward until the first gear  121 A abuts against the second gear  121 B. 
     The spring  29  is fitted around the shaft  128 , between the first gear  121 A and the second gear  121 B, in a state in which the spring  29  is compressed from the natural length thereof. 
     According to this structure, in a state in which no external force is applied, the first gear  121 A of the operation knob  121  is urged leftward by the urging force of the spring  29  and, as illustrated in  FIG. 12A , the first gear  121 A is in a state of being disposed at a leftmost side and separated from the second gear  121 B. Hereinafter, the position of the first gear  121 A in this state is referred to as “the separated position”. 
     In this state, the gear part  121 AC of the first gear  121 A does not mesh with any of the gears and is in a free state. Meanwhile, the second gear  121 B meshes with the gear  32  but is separated from the first gear  121 A. 
     Therefore, even if the first gear  121 A of the operation knob  121  is rotated, the second gear  121 B and any other gears cannot be rotated. Thus, the operation knob  121  is rotated without effect. 
     On the other hand, when an external force is applied to the first gear  121 A of the operation knob  121 , such as when the operation knob  121  is pushed into the rightward, the first gear  121 A moves rightward while compressing the spring  29  and, as illustrated in  FIG. 12B , goes into a state in which the protrusions  121 AP are fitted into the hole portions  121 BH and the first gear  121 A is joined to the second gear  121 B. Hereinafter, the position of the first gear  121 A in this state is referred to as “the joining position”. 
     At the operation knob  121 , if the first gear  121 A is simply moved to the rightward, the positions of the protrusions  121 AP and the hole portions  121 BH of the second gear  121 B may not match up and the protrusions  121 AP and hole portions  121 BH may not be joined. In this case, the protrusions  121 AP may be fitted into the hole portions  121 BH by the first gear  121 A of the operation knob  121  being suitably rotated while being pushed into the rightward. 
     In this state, the gear part  121 AC of the first gear  121 A is meshed with the gear  35 , while the second gear  121 B is continuously meshed with the gear  32 . If a rotary force about the shaft  128  is further applied to the first gear  121 A, the rotary force may be transmitted via the protrusions  121 AP to the second gear  121 B. 
     Therefore, when the first gear  121 A of the operation knob  121  is rotated, the second gear  121 B rotates integrally therewith. Thus, driving force is transmitted to both the gear  32  and the gear  35  and, the same as in the first embodiment, the drum  27  and the conveyance rollers  24  and driven rollers  25  may be rotated simultaneously. 
     From the joining position, when the external force to rightward is released, the first gear  121 A of the operation knob  121  is moved in the leftward direction by the restoring force of the spring  29 , and returns to the separated position ( FIG. 12A ). 
     Thus, the temporary holding section  115  is structured such that, during usual operations, the first gear  121 A of the operation knob  121  is retained at the separated position and is separated from the gears  32  and  35 . On the other hand, during maintenance operations, if the first gear  121 A is pushed into the joining position, rotary driving force may be transmitted from the operation knob  121  to the gears  32  and  35 . 
     2-2. Structure of the Operation Restriction Plate 
     At the operation restriction plate  141 , as illustrated in  FIG. 13 , the cutout portion  41 X of the operation restriction plate  41  according to the first embodiment is omitted, and the operation restriction plate  141  is in a shape that is elongated upward. 
     As illustrated in  FIG. 14A  and  FIG. 15 , the operation restriction plate  141  is formed so as to cover the first gear  121  A of the operation knob  121  when the temporary holding section  115  is in the mounted state. 
     Thus, the operation restriction plate  141  may be an obstruction such that the first gear  121 A of the operation knob  121  cannot be operated by a maintenance technician. That is, the operation restriction plate  141  impedes movement of the first gear  121 A in the rightward direction, and keeps the first gear  121 A at the separated position, that is, in the state in which the first gear  121 A is not joined to the second gear  121 B and the gear part  121 AC is not meshed with the gear  35 . 
     On the other hand, as illustrated in  FIG. 14B , when the temporary holding section  115  is turned from the mounted state in the direction of arrow U 1  ( FIG. 3 ) to the detached state, the first gear  121 A of the operation knob  121  is exposed from the operation restriction plate  141 . 
     In this state of the operation knob  121 , operation of the first gear  121 A by a maintenance technician is possible. Thus, if an external force to the rightward is applied, the first gear  121 A may be moved to the joining position and, as illustrated in  FIG. 12B , the first gear  121 A may be joined with the second gear  121 B and the gear part  121 AC may be meshed with the gear  35   
     When the temporary holding section  115  is turned back from the detached state in the direction of arrow U 2  ( FIG. 3 ) to the mounted position, the operation restriction plate  141  again covers the first gear  121 A of the operation knob  121 . Thus, the operation restriction plate  141  impedes operations of the first gear  121 A such as pushing in, rotating and the like, and the first gear  121 A is kept at the separated position. 
     Thus, the operation restriction plate  141  is structured to keep the first gear  121 A at the separated position and to impede joining with the second gear  121 B and meshing between the gear part  121 AC and the gear  35  by the operation restriction plate  141  covering the first gear  121 A of the operation knob  121  only when the temporary holding section  115  is in the mounted state. 
     2-3. Operation and Effects 
     In the structure described above, the banknote processing section  111  of the ATM  101  according to the second embodiment is configured such that the temporary holding section  115  is structured to be turnable relative to the banknote processing section frame  11 F, and the operation knob  121  is structured with the first gear  121 A and second gear  121 B that are joined to or separated from one another. 
     In the temporary holding section  115 , the first gear  121 A of the operation knob  121  is movable between the separated position and the joining position. When the first gear  121 A is at the joining position, the first gear  121 A is joined to the second gear  121 B and the gear part  121 AC is meshed with the gear  35 . 
     When the temporary holding section  115  is at the mounted position, the operation restriction plate  141  mounted at the banknote processing section frame  11 F covers the first gear  121 A of the operation knob  121  ( FIG. 13 ,  FIG. 14A  and  FIG. 15 ). 
     Therefore, at the temporary holding section  115 , a maintenance technician may be prevented from touching the first gear  121 A of the operation knob  121 , and the first gear  121 A may be kept at the separated position. 
     Thus, the same as in the first embodiment, the drum  27 , the conveyance rollers  24  and the like inside the temporary holding section  115  are not rotated while the temporary holding section  115  is in the mounted state. Therefore, even if banknotes BL are being stored inside the temporary holding section  115 , these banknotes BL are not conveyed. 
     As a result, the same as in the first embodiment, situations such as banknotes BL moving to be fed out through the transfer aperture  23  and getting jammed in the conveyance path  26 , the drum  27  and tape (not illustrated in the drawings) or the like being damaged by jammed banknotes BL, the jammed banknotes BL themselves being damaged, and so forth may be pre-emptively prevented in the temporary holding section  115 . 
     Because the operation restriction plate  141  is structured by a thick metal plate, even if a maintenance technician forcibly or accidentally applies an external force, there is little danger of the operation restriction plate  141  being deformed or broken, and the first gear  121 A of the operation knob  121  may continue to be kept at the withdrawn position. 
     On the other hand, when the temporary holding section  115  is turned from the mounted state in the direction of arrow U 1  ( FIG. 3 ) to the detached state, the first gear  121 A of the operation knob  121  may be exposed from behind the operation restriction plate  141  ( FIG. 14B ). 
     Thus, only in the detached state in which the transfer aperture  23  is separated from the conveyance section  13  of the banknote processing section  111  and the banknotes BL may be fed out, operation of the operation knob  121  of the temporary holding section  115  is allowed, the first gear  121 A may be moved to the joining position and joined to the second gear  121 B, the gear part  121 AC may be meshed with the gear  35 , and the drum  27  and the conveyance rollers  24  and the like may be rotated. 
     According to the structure described above, in the banknote processing section  111  of the ATM  101 , when the temporary holding section  115  is in the mounted state, the first gear  121 A of the operation knob  121  is covered by the operation restriction plate  141  and retained at the separated position. Thus, driving force is not transmitted to the gears  32  and  35 , and rotary operations of the drum  27 , the conveyance rollers  24  and the like may be restricted. On the other hand, when the temporary holding section  115  of the banknote processing section  111  is turned to the detached state, the first gear  121 A of the operation knob  121  is exposed from behind the operation restriction plate  141 . Thus, the first gear  121 A of the operation knob  121  of the temporary holding section  115  may be moved from the separated position to the joining position, the first gear  121 A may be joined to the second gear  121 B 2  and the gear part  121 AC may be meshed with the gear  35 , and rotary operations of the drum  27 , the conveyance rollers  24  and the like via the operation knob  121  may be enabled. 
     3. Alternative Embodiments 
     In the first embodiment described above, a case is described in which the cutout portion  41 X of the operation restriction plate  41  is formed in a U shape as viewed in the left-right direction. 
     However, embodiments are not limited thus. The shape of the cutout portion may be a variety of shapes such as, for example, a crank shape, a V shape, a shape with multiple sides. In these cases, it is sufficient that the operation knob  21  may be retained at the withdrawn position by reliable engagement of the cutout portion with the slot portion  21 R of the operation knob  21  when the temporary holding section  15  is in the mounted state. 
     In the first embodiment described above, a case is described in which the portion of the operation restriction plate  41  extending upward from the upper face of the banknote processing section frame  11 F is formed in a plate shape. 
     However, embodiments are not limited thus. For example, a rod-shaped member may be machined and formed into a Y shape, a V shape or the like as viewed in the left-right direction. That is, it is sufficient that the operation restriction plate  41  reliably engages with the slot portion  21 R of the operation knob  21  only when the temporary holding section  15  is in the mounted state, and is strong enough to not be easily deformed. 
     In the first embodiment described above, a case is described in which the slot portion  21 R is formed at the operation knob  21  and the slot portion  21 R is engaged with the cutout portion  41 X of the operation restriction plate  41 . 
     However, embodiments are not limited thus. For example, the slot portion  21 R may be omitted from the operation knob  21 , the diameter of the semi-circular portion of the cutout portion  41 X may be made slightly larger than the outer diameter of the shaft  28 , and the cutout portion  41 X may be engaged with the vicinity of a location of the connection between the operation knob  21  and the shaft  28 . 
     In the first embodiment described above, a case is described in which an upper end portion of the operation restriction plate  41  reaches the upper side relative to point P, the axial center of the operation knob  21 , when the cutout portion  41 X of the operation restriction plate  41  is engaged with the slot portion  21 R of the operation knob  21 , and the middle of the operation knob  21  is sandwiched and engaged from both sides. 
     However, embodiments are not limited thus. The upper end portion of the operation restriction plate  41  may stop at the lower side relative to the axial center point P of the operation knob  21  when the cutout portion  41 X of the operation restriction plate  41  is engaged with the slot portion  21 R of the operation knob  21 . 
     In the second embodiment described above, a case is described in which the operation knob  121  is completely covered by the operation restriction plate  141  when the temporary holding section  115  is in the mounted state. 
     However, embodiments are not limited thus. For example, a portion of the operation knob  121  may be exposed from the operation restriction plate  141  when the temporary holding section  115  is in the mounted state. In this case, it is sufficient that the operation knob  121  may be impeded such that a maintenance technician may not push in the first gear  121 A of the operation knob  121  and the first gear  121 A may not be joined to the second gear  121 B. 
     Cases are described above in which, in the first embodiment, the operation knob  21  is integrally structured, and in the second embodiment, the operation knob  121  is structured with the first gear  121 A and the second gear  121 B being separable. 
     However, embodiments are not limited thus. For example, in the first embodiment, the operation knob  21  may be structured to be separable similarly to the second embodiment, and in the second embodiment, the operation knob  121  may be integrally structured similarly to the first embodiment. 
     In the first embodiment described above, a case is described in which, when the operation knob  21  is moved to the meshing position, the operation knob  21  meshes with both the gear  32  for driving the drum  27  and the gear  35  for driving the conveyance rollers  24  and the like. 
     However, embodiments are not limited thus. When the operation knob  21  is moved to the meshing position, it may mesh with only one of the gear  32  and the gear  35 , or may mesh with three or more gears. The same applies to the second embodiment. 
     In the second embodiment described above, a case is described in which the number of the protrusions  121 AP provided at the first gear  121 A and the number of the hole portions  121 BH provided at the second gear  121 B are both two. 
     However, embodiments are not limited thus. For example, the numbers of the protrusions  121 AP and hole portions  121 BH may be arbitrary numbers, such as both being four, six or the like. Furthermore, the number of the protrusions  121 AP may be smaller than the number of the hole portions  121 BH. 
     In the first embodiment described above, a case is described in which rotary force is transmitted by gears meshing with one another, meshing between the gear portion  21 C of the operation knob  21  and the gears  32  and  35  or the like. 
     However, embodiments are not limited thus. For example, rubber members or the like with large friction forces may be installed at outer peripheries of disc-shaped members and rotary force may be transmitted by these disc-shaped members abutting against one another. That is, it is sufficient that a rotary force applied via the operation knob be transmitted to another member. The same applies to the second embodiment. 
     In the first embodiment described above, a case is described in which the temporary holding section  15  is switched to the mounted state or the detached state by being turned about the turning shaft  22  relative to the banknote processing section frame  11 F of the banknote processing section  11 . 
     However, embodiments are not limited thus. For example, the temporary holding section  15  may be switched to the mounted state or the detached state by being slid along a predetermined slide rail relative to the banknote processing section frame  11 F. In this case, it is sufficient that a direction of formation of the cutout portion  41 X corresponds with the direction of movement of the temporary holding section  15 . The same applies to the second embodiment. 
     In the first embodiment described above, a case is described in which the present invention is applied to the temporary holding section  15  that temporarily retains banknotes BL. 
     However, embodiments are not limited thus. For example, the present invention may be applied to various sections in the ATM  1 , such as a portion of the conveyance section  13 , the banknote storage section  12  or the banknote storages  17 . In these cases, it is sufficient that section is structured to be mountable and detachable relative to the banknote processing section frame  11 F or the like and includes an operation knob for maintenance operations, and, by an operation restriction plate that is provided at the banknote processing section frame  11 F or the like, feeding operations of banknotes BL by the operation knob are restricted in a state in which that section is mounted and such operations by the operation knob are allowed in a state in which that section is detached. The same applies to the second embodiment. 
     In the first embodiment described above, a case is described in which the medium is banknotes being stored at the temporary holding section  15  of the ATM  1 . 
     However, embodiments are not limited thus. For example, the present invention may be applied to a variety of devices storing, for example, paper-form media such as merchandise coupons, money certificates or event tickets, or a medium such as coins. The same applies to the second embodiment. 
     In the first embodiment described above, a case is described in which the banknote processing section  11  serving as a medium processing device is structured by the temporary holding section  15  serving as a temporary holding section, the gears  32  and  35  serving as gears, the banknote processing section frame  11 F serving as a main body, the operation knob  21  serving as an operation knob, and the operation restriction plate  41  serving as an operation restriction portion. 
     However, embodiments are not limited thus. The medium processing device may be structured by a temporary holding section, gear(s), main body, operation knob and operation restriction portion that have numerous alternative structures.
