Title: Media processing device

Description:
TECHNICAL FIELD 
     The present invention relates to a media processing device, and is suitable for application to, for example, an automatic teller machine (ATM) in which media such as bank notes or the like are inserted and that carries out a desired transaction, or the like. 
     BACKGROUND ART 
     Conventionally, at automatic teller machines and the like that are used in financial institutions or stores or the like, for example, a client deposits cash such as bank notes or coins or the like, or cash is dispensed to the client, in accordance with the contents of the transaction with the client. 
     There have been proposed automatic teller machines that have, for example, a bank note deposit/withdrawal opening that carries out the transfer of bank notes to and from clients, a discriminating section that discriminates the denomination and the authenticity of an inserted bank note, a temporary holding section that temporarily holds inserted bank notes, storage containers that store bank notes per denomination, and a reject container that stores reject bank notes that have been discriminated by the discriminating section as being bank notes that are not to be transacted. 
     In the automatic teller machine, a unit housing, in which the plural storage containers are housed, is provided within the secure housing of the whole automatic teller machine, and the bank notes and the like that are stored in the storage containers are protected. On the other hand, when maintenance work or the like of respective sections of the automatic teller machine is carried out, a bank clerk or maintenance worker or the like of the financial institution must access the interior of the automatic teller machine. 
     Thus, there have been proposed automatic teller machines at which the front surface or the back surface of the housing is structured by a door that can open and close, and that are structured such that the unit housing can be pulled out to the exterior by a predetermined sliding mechanism or the like in a state in which the door has been opened (see, for example, Japanese Utility Model Application Publication (JP-Y) No. H06-31571 ( FIG. 1 )). 
     At an automatic teller machine  401  shown in  FIG. 14 , plural storage containers  12 A to  12 E are disposed so as to be lined-up in the front-rear direction within a unit housing  418 , and a reject container  413  is disposed at the front-most portion. 
     When the storage containers  12 A to  12 E that are housed within the unit housing  418  are to be removed, a bank clerk opens a front surface door  2 A of a housing  2 , and, as shown in  FIG. 15 , pulls the unit housing  418  out to the front, and removes the predetermined storage containers  12 A to  12 E, that have been exposed to the exterior, from the unit housing  418 . 
     SUMMARY OF INVENTION 
     Technical Problem 
     With such an automatic teller machine, a wide space into which the unit housing is pulled out must be ensured in front. Therefore, in a case in which the surface area in front of the place where the automatic teller machine is set is narrow, there are cases in which it is difficult to pull the entire unit housing out to the front. 
     In such cases, installation and removal of the storage containers that are disposed at the rear side in particular are difficult, and the ease of use is poor. 
     The present invention provides a media processing device having improved ease of use. 
     Solution to Problem 
     A first aspect of the present invention is a media processing device including: a housing having a predetermined space at an interior thereof, and at which an opening portion is formed in at least one side surface; a drawer that houses a first storage container that stores media, and that can be accommodated within the housing, and that is provided so as to be able to be pulled out along a pull out direction to an exterior of the housing via the opening portion; and a media storage section that is structured so as to be able to be attached to and removed from the drawer at a distal end side, in the pull out direction, of the drawer, and that stores media. 
     Due thereto, in the first aspect of the present invention, at the time of pulling the drawer out from the housing, the space that is needed in front of the housing may be reduced by removing the media storage section from the drawer. 
     Advantageous Effects of Invention 
     In the first aspect of the present invention, at the time of pulling the drawer out from the housing, the space that is needed in front of the housing may be reduced by removing the media storage section from the drawer. Thus, the present invention may realize a media processing device having improved ease of use.

     DESCRIPTION OF EMBODIMENTS 
     Forms for implementing the present invention (hereinafter called exemplary embodiments) are described hereinafter by using the drawings. 
     [1. First Exemplary Embodiment] 
     [1-1. External Structure of Automatic Teller Machine] 
     As shown in  FIG. 1 , an automatic teller machine  1  is a bank clerk operated terminal that a bank clerk of a financial institution (e.g., a clerk at the reception counter) operates, and carries out deposit/withdrawal processing of bank notes on the basis of operations of the bank clerk. 
     At this automatic teller machine  1 , an insertion opening  3 A of a deposit section  3 , a dispensing opening  4 A of a withdrawal section  4 , a display section  5  and an operation section  6  are provided at the upper end portion of the housing  2  that is box-shaped. 
     The front surface door  2 A that can open and close is provided at the side surface at the front surface side of this housing  2 . The housing  2  protects bank notes that are stored in the automatic teller machine  1  by respective doors being closed at the time of a transaction operation in which a transaction relating to cash is carried out with the bank clerk. On the other hand, at the housing  2 , at the time of maintenance work in which a maintenance worker or the like carries out maintenance work, work on the respective sections at the interior may be easily carried out by the front surface door  2 A being opened as needed. 
     When bank notes to be deposited are inserted in from the insertion opening  3 A by the bank clerk, the deposit section  3  separates these bank notes one-by-one and takes the bank notes into the interior of the automatic teller machine  1 . 
     The withdrawal section  4  is structured so as to stack bank notes for withdrawal, and to have the bank clerk take the bank notes out from the dispensing opening  4 A. Further, a shutter (not shown) that opens and closes the dispensing opening  4 A is provided at the withdrawal section  4 , and opens at the time of dispensing bank notes. 
     The display section  5  is configured by a liquid crystal display, and displays menu screens, screens of the results of various types of processings, and the like. The operation section  6  is configured by push buttons, and receives operations with respect to the automatic teller machine  1 . 
     Moreover, although not illustrated, the automatic teller machine  1  can communicate with terminals or the host computer of the financial institution via a network, and can transmit and receive various types of information to and from the terminals and host computer, and can be operated from the terminal sides. 
     [1-2. Internal Structure of Automatic Teller Machine] 
     As shown in  FIG. 2 , the automatic teller machine  1  has, at the upper side and in addition to the above-described deposit section  3  and withdrawal section  4 , a discriminating section  10  and a temporary holding section  11 . 
     A bank note storage section  15  is provided at the lower side of the automatic teller machine  1 . The bank note storage section  15  is structured from a unit housing  18  that houses the storage containers  12 A to  12 E, and a reject container  13  that is housed in a reject container housing case  30  that is provided at the outer side of the front surface of the unit housing  18 . 
     Moreover, a conveying path  14 , that connects these respective sections that are the deposit section  3 , the withdrawal section  4 , a discriminating section  10 , the temporary holding section  11 , the storage containers  12 A to  12 E and the reject container  13 , is provided within the housing  2 . 
     The deposit section  3  has a storage section  3 B that is shaped as a box and whose top surface is open. A portion of the opening of the storage section  3 B is the aforementioned insertion opening  3 A. At the time of a deposit transaction, the deposit section  3  separates one-by-one the bank notes to be deposited that have been inserted into the storage section  3 B from the insertion opening  3 A, and takes the bank notes into the interior of the automatic teller machine  1 . 
     The withdrawal section  4  has a stacking portion  4 B that is shaped as a box and whose top surface is open. The opening of this stacking portion  4 B is the aforementioned dispensing opening  4 A. At the time of a withdrawal transaction, the withdrawal section  4  stacks, in the stacking portion  4 B, the bank notes for withdrawal that have been conveyed from the storage containers  12 A to  12 E and the like. 
     Further, a shutter (not illustrated) for opening and closing the dispensing opening  4 A is provided at the withdrawal section  4 . This shutter opens after the bank notes for withdrawal have been stacked in the stacking portion  4 B. Due to the shutter opening, the bank clerk can take the bank notes for withdrawal, that are stacked in the stacking portion  4 B, out from the dispensing opening  4 A. 
     The deposit section  3  and the withdrawal section  4  are fixed in states of being inclined forward, such that the upper end portions thereof are positioned further forward than the lower end portions thereof. 
     The discriminating section  10  discriminates the denomination, the authenticity, the undamaged/damaged state, the travelling state, and the like of the bank notes that are conveyed one-by-one via the conveying path  14 . This discriminating section  10  judges, per bank note and on the basis of the results of discrimination thereof, whether or not a bank note is a normal bank note that can be handled or is a reject bank note that cannot be handled. 
     The temporary holding section  11  temporarily stacks the bank notes that have been taken-in from the deposit section  3  and have been determined by the discriminating section  10  as being normal bank notes. After a transaction is established, the bank notes that are stacked in the temporary holding section  11  are sent out from the temporary holding section  11  and conveyed to the discriminating section  10 , and, after the denominations thereof are specified by the discriminating section  10 , the bank notes are conveyed to and stored in the storage containers  12 A to  12 E. 
     The unit housing  18  is formed in the shape of a box by a metal plate or a molded article that is strong and has a predetermined thickness. The plural storage containers  12 A to  12 E, that have been readied per denomination of the bank notes, are disposed in the interior of the unit housing  18  so as to be lined-up in the front-rear direction. 
     The respective storage containers  12 A to  12 E have internal spaces that are vertically long and that can accommodate bank notes per denomination, and stack the bank notes, that are conveyed via the conveying path  14 , in piles in the top-bottom direction at the interiors thereof. 
     Further, the storage containers  12 A to  12 E not only store bank notes, but also can send the bank notes, that are stacked in the interiors thereof, out to the conveying path  14  one-by-one. Moreover, the storage containers  12 A to  12 E can be installed in and removed from the unit housing  18  individually by being pulled out upward. 
     Further, a pull out lever  20  is mounted to a unit housing front surface plate  18 F that is the side wall at the front surface of the unit housing  18 . The bank clerk can pull the unit housing  18  out from the housing  2  by grasping this pull out lever  20  and pulling it forward. 
     The reject container housing case  30  is a detachable type that can be attached to and removed from the unit housing  18 . The reject container  13 , that stacks the bank notes that have been determined as being reject bank notes by the discriminating section  10 , is housed in the reject container housing case  30 . 
     By the way, the unit housing  18  is attached to the housing  2  via unillustrated slide rails. These slide rails are structured from a combination of rail-shaped parts that extend in the front-rear direction, and plural rollers, and the like, and rectilinearly and smoothly move the unit housing  18  in the frontward direction or the rearward direction. 
     Further, the slide rails prescribe a range of movement of the unit housing  18  with respect to the housing  2 , and move the unit housing  18  between the positions shown in  FIG. 2  and  FIG. 3 . 
     At the automatic teller machine  1 , when deposit or withdrawal processing is to be carried out, the bank notes and the like that are stored in the storage containers  12  within the unit housing  18  are protected due to the unit housing  18  being accommodated within the housing  2  as shown in  FIG. 2 . Hereinafter, this state is called the accommodated state of the unit housing  18 . 
     On the other hand, at the automatic teller machine  1 , when replenishing or collecting of bank notes is to be carried out, the front surface door  2 A is opened, the unit housing  18  is moved in the frontward direction as shown in  FIG. 3  from the opening portion that penetrates the internal space and the exterior of the housing  2 , and substantially the entire unit housing  18  is set in a state of being pulled out to the exterior of the housing  2 . 
     Hereinafter, the state in which the unit housing  18  is pulled out toward the front side from the position of the accommodated state is called the pulled out state, regardless of whether or not substantially the entire unit housing  18  has been pulled out from the housing  2 . 
     At this time, the reject container housing case  30  is pulled out from the housing  2  together with the unit housing  18  in a state of being attached to the unit housing  18 . 
     If there is sufficient space at the front surface of the automatic teller machine  1 , the bank clerk, without removing the reject container housing case  30  from the unit housing  18 , pulls out substantially the entire unit housing  18  to the exterior of the housing  2 , and removes the predetermined storage containers  12 A to  12 E from the unit housing  18 , and carries out collection or replenishment of bank notes. 
     On the other hand, if there is not sufficient space at the front surface of the automatic teller machine  1 , the bank clerk pulls the unit housing  18  out slightly to the exterior of the housing  2 , and removes the reject container housing case  30  from the unit housing  18 . Then, as shown in  FIG. 4 , the bank clerk pulls substantially the entire unit housing  18  out to the exterior of the housing  2 , and removes the predetermined storage containers  12 A to  12 E from the unit housing  18 , and carries out collection or replenishment of bank notes. 
     Hereinafter, the state in which the reject container housing case  30  is removed from the unit housing  18  is called the removed state. 
     With this structure, at the automatic teller machine  1 , a control section controls the respective sections on the basis of the results of discrimination of bank notes by the discriminating section  10 , or the like, and carries out deposit processing or withdrawal processing of bank notes. 
     Namely, at the automatic teller machine  1 , at the time of a deposit transaction, when deposit transaction is selected by the bank clerk via the operation section  6 , and further, bank notes are inserted into the deposit section  3  from the insertion opening  3 A, the inserted bank notes are conveyed one-by-one to the discriminating section  10 . 
     Here, the automatic teller machine  1  conveys bank notes, that have been determined by the discriminating section  10  as being normal bank notes, to the temporary holding section  11  and stores the bank notes temporarily. On the other hand, the automatic teller machine  1  returns bank notes, that have been determined as being deposit reject bank notes that are unsuited for depositing, to the withdrawal section  4 , and, by opening the shutter, returns the bank notes to the bank clerk. 
     Thereafter, when the deposit amount is confirmed by the bank clerk, the automatic teller machine  1  conveys the bank notes, that are stored in the temporary holding section  11 , to the discriminating section  10  and discriminates the denominations, and, in accordance with the denominations thereof, conveys the bank notes to and stores the bank notes in the respective storage containers  12 A to  12 E. 
     On the other hand, at time of a withdrawal transaction, when withdrawal transaction is selected and the amount for withdrawal is inputted by the bank clerk via the operation section  6 , the automatic teller machine  1  identifies the number of bank notes of each denomination that is needed in accordance with the requested amount, and sends the bank notes out one-by-one from the respective storage containers  12 A to  12 E in accordance with the number of bank notes per denomination, and conveys the bank notes to the discriminating section  10 . 
     Here, the automatic teller machine  1  conveys bank notes, that are determined by the discriminating section  10  as being normal bank notes, to the withdrawal section  4 . On the other hand, the automatic teller machine  1  conveys bank notes, that are determined as being withdrawal reject bank notes that are unsuitable for withdrawal, to the temporary holding section  11  and temporarily stores the bank notes. 
     Then, when the bank notes of the requested amount are stacked in the withdrawal section  4 , the automatic teller machine  1  opens the shutter. Due thereto, there becomes a state in which receipt of the bank notes that are stacked within the withdrawal section  4  is possible, and the bank clerk accepts the bank notes. 
     Thereafter, the automatic teller machine  1  conveys the withdrawal reject bank notes, that are stored in the temporary holding section  11 , to the reject container  13  and stores them therein. 
     In this way, the automatic teller machine  1  carries out depositing processing and withdrawal processing of bank notes. 
     [1-3. Structures of Unit Housing and Reject Container Housing Case] 
     As shown in  FIG. 5A  and  FIG. 5B , the reject container housing case  30  is formed by a single steel plate that is bent and welded, and in the shape of a box whose top and back are open. Note that, for convenience of explanation, a lock portion  46  that is described hereafter is omitted from illustration in  FIG. 5A ,  FIG. 5B ,  FIG. 8A  and  FIG. 8B . 
     At the reject container housing case  30 , a predetermined space is formed at the interior by a housing case front surface plate  30 F that is the front surface plate, a housing case bottom plate  30 B that is the bottom plate, a housing case right side plate  30 R that is the right side surface plate, a housing case left side plate  30 L that is the left side surface plate, and the unit housing front surface plate  18 F. 
     Further, the housing case front surface plate  30 F and the unit housing front surface plate  18 F restrict movement of the reject container  13  in the front-rear direction, and the housing case right side plate  30 R and the housing case left side plate  30 L restrict movement of the reject container  13  in the left-right direction. 
     The upper end portions of the housing case right side plate  30 R and the housing case left side plate  30 L are shapes that are bent toward the right side and the left side respectively, and thereafter, are bent toward the lower side. Due thereto, the cut-section of the steel plate is prevented from being exposed at the upper end portion. 
     Further, the left side end portion and the right side end portion of the steel plate that forms the housing case bottom plate  30 B are bent upward, and are welded to the outer wall surfaces of the housing case left side plate  30 L and the housing case right side plate  30 R, respectively. 
     A housing case lower portion vertical plate  30 BV, that is bent downward at the rear end portion, is formed at the housing case bottom plate  30 B. 
     The reject container  13  is housed within the reject container housing case  30 . This reject container  13  is formed in the shape of a box and stores reject bank notes at the interior thereof. 
     Further, a handle  32  is provided at the upper portion of the reject container  13 . Due to the bank clerk grasping this handle  32 , the bank clerk can install and remove the reject container  13  into and from the reject container housing case  30  via the opening of the top surface of the reject container housing case  30 . 
     L-shaped (hook-shaped) catch-on portions  34  are formed so as to head rearward from the rear end portions near to the upper portions of the housing case left side plate  30 L and the housing case right side plate  30 R. As shown in  FIG. 6 , the catch-on portion  34  has a hook portion  35  that extends rearward, and thereafter, is bent downward. 
     Abutting portions  33  that project rearward are formed at the rear end portions of the housing case right side plate  30 R and the housing case left side plate  30 L, beneath the catch-on portions  34 . 
     Further, slit holes  36 , that penetrate the front and rear of the unit housing front surface plate  18 F (i.e., the exterior and the interior of the unit housing  18 ), are formed in the unit housing front surface plate  18 F along the vertical direction and at positions that face the catch-on portions  34  of the reject container housing case  30 . 
     A vertical length D of the slit hole  36  is formed to be longer than a vertical length d of the catch-on portion  34 . Due thereto, at the automatic teller machine  1 , the catch-on portions  34  can be fit into the slit holes  36  along a rearward direction. 
     Further, a catch-on portion gap t, that is the gap in the front-rear direction between the hook portion  35  of the catch-on portion  34  and the rear end surface of the abutting portion  33 , is formed to be slightly larger than plate thickness T of the unit housing front surface plate  18 F. 
     Here, if the catch-on portion gap t is too large with respect to the plate thickness T, at the time of attaching the reject container housing case  30  to the unit housing  18 , the reject container housing case  30  will rattle with respect to the unit housing  18 . If, in this state, the bank clerk abruptly touches the reject container housing case  30  and the position of the reject container housing case  30  becomes offset from a predetermined position with respect to the unit housing  18 , there is the possibility that a jam will arise when bank notes are conveyed to the reject container  13  in the accommodated state of the unit housing  18 . 
     On the other hand, if the catch-on portion gap t is small with respect to the plate thickness T, the reject container housing case  30  cannot be fit into the unit housing  18 . 
     In contrast, at the automatic teller machine  1 , by structuring the catch-on portion gap t to be slightly larger than the plate thickness T, rattling of the reject container housing case  30  with respect to the unit housing  18  is prevented while poor assembly is prevented. 
     Further, at the automatic teller machine  1 , the entire regions beneath the catch-on portions  34  at the rear end portions of the housing case right side plate  30 R and the housing case left side plate  30 L do not abut the unit housing front surface plate  18 F, and only the abutting portions  33  abut the unit housing front surface plate  18 F. Due thereto, it suffices for places that have dimensional tolerance to be narrow, and therefore, machining may be carried out easily. 
     A slotted portion  38 , that is cut out upward from the lower end, is formed in the left-right direction central portion of the lower end of the housing case lower portion vertical plate  30 BV ( FIG. 5A ,  FIG. 5B ). 
     A screw hole  40 , that is round as seen in front view and that penetrates the front and the rear of the unit housing front surface plate  18 F (i.e., the exterior and interior of the unit housing  18 ), is formed in the unit housing front surface plate  18 F at a position facing the slotted portion  38  in the state in which the reject container housing case  30  is attached. A screw  42  having a knob portion, that can fasten the reject container housing case  30  and the unit housing  18 , is screwed-together with this screw hole  40 . 
     A screw portion  42 A, that passes-through the unit housing front surface plate  18 F from the front toward the rear, and a knob portion  42 B, that is provided at the front of the screw portion  42 A and whose diameter is formed to be larger than that of the screw portion  42 A so as to be easily pinched by fingers of a worker, are formed at the screw  42  having a knob portion. The screw portion  42 A has a length in the front-rear direction that is sufficiently longer than the plate thickness T. 
     In this structure, when the reject container housing case  30  is to be attached to the unit housing  18 , as shown in  FIGS. 7A  to C, from the state of  FIG. 7A , by inserting the catch-on portions  34  of the reject container housing case  30  along the horizontal direction into the slit holes  36  of the unit housing  18 , and, at the position where the hook portions  35  have completely entered into the slit holes  36  ( FIG. 7B ), lowering the reject container housing case  30  along the vertical direction, the catch-on portions  34  are fit-together with the slit holes  36 . 
     At this time, as shown in  FIG. 8A  and  FIG. 8B , due to the screw  42  with a knob portion fitting into the slotted portion  38 , the reject container housing case  30  is set at a predetermined position with respect to the unit housing  18 . 
     Next, due to the bank clerk turning the knob portion  42 B in the fastening direction, the housing case lower portion vertical plate  30 BV is nipped-in between the knob portion  24 B and the unit housing front surface plate  18 F, and the reject container housing case  30  is thereby fixed to the unit housing  18 . 
     On the other hand, when the reject container housing case  30  is to be removed from the unit housing  18 , first, the bank clerk pulls the unit housing  18 , to which the reject container housing case  30  is attached, out from the housing  2  to the front. 
     Next, due to the bank clerk turning the knob portion  42 B in the loosening direction, and lifting the reject container housing case  30  up along the vertical direction ( FIG. 7B ), and pulling the catch-on portions  34  out from the slit holes  36  in the horizontal direction ( FIG. 7A ), the reject container housing case  30  is removed from the unit housing  18 . 
     At this time, because the screw portion  42 A has a length in the front-rear direction that is sufficiently longer than the plate thickness T of the unit housing front surface plate  18 F, the screw  42  having a knob portion does not easily come out from the unit housing front surface plate  18 F. 
     [1-4. Structures of Reject Container Housing Case and Reject Container] 
     As shown in  FIG. 9 , the lock portion  46 , that makes the reject container  13  installable in and removable from the reject container housing case  30 , is provided at the housing case left side plate  30 L. 
     The lock portion  46  is mainly formed by a hook member  48  that hooks on the reject container  13 , and a driving member  50  that can move the hook member  48 . 
     The hook member  48  is L-shaped as seen in front view, and is structured from a claw portion  52  that is hook-shaped and formed at the upper end portion, and an operation section  54  that extends toward the left side at the lower end portion. Further, a sliding surface  56 , that is inclined from left to right while heading from top to bottom, is formed at the right side upper portion of the claw portion  52 . Further, the driving member  50  is structured from a shaft  58  and a spring  60 . 
     A lock portion hole  62 , that is rectangular as seen in side view and that penetrates the left side and the right side of the housing case left side plate  30 L (i.e., the exterior and the interior of the reject container housing case  30 ), is formed in the housing case left side plate  30 L at a position facing the claw portion  52 . 
     The shaft  58 , that is cylindrical and extends along the front-rear direction and whose front end and rear end are fixed to the housing case left side plate  30 L, passes-through the right end of the lower end portion of the hook member  48 . Due thereto, the hook member  48  is structured so as to be able to rotate with the shaft  58  as the point of support. 
     The spring  60  that is a torsion spring is fit-on the shaft  58  at the rear side of the hook member  48 . At this spring  60 , a wound portion  60 C, that is the central portion of a single metal rod, is wound on the shaft  58 , and a lower arm portion  60 L extends downward from this wound portion  60 C, and an upper arm portion  60 U extends upward and, thereafter, is bent forward. 
     At the spring  60 , in a state in which the upper end portion of the upper arm portion  60 U and the lower end portion of the lower arm portion  60 L are positioned further toward the left side than the natural state, the upper end portion of the upper arm portion  60 U and the lower end portion of the lower arm portion  60 L abut the hook member  48  and the housing case left side plate  30 L, respectively. 
     Therefore, the spring  60  applies urging force, in the direction of entering into the lock portion hole  62 , to the claw portion  52  due to the repulsive force that attempts to return the spring  60  to its natural state. 
     On the other hand, a reject container hole  64 , that is rectangular as seen in side view and that penetrates the left side and the right side of a reject container left side plate  13 L (i.e., the exterior and the interior of the reject container  13 ), is formed in the reject container left side plate  13 L, that is the left side surface plate of the reject container  13 , at a position facing the lock portion hole  62  of the reject container housing case  30 . 
     Therefore, in the state in which the reject container  13  is housed in the reject container housing case  30 , due to the claw portion  52  being inserted through the lock portion hole  62  and being hooked on the reject container hole  64 , the reject container  13  is locked in the interior of the reject container housing case  30 . 
     In this structure, at the time when the reject container  13  is to be housed in the reject container housing case  30 , when the bank clerk grasps the handle  32  of the reject container  13 , and, as shown in  FIG. 10A , inserts the reject container  13  in from above the reject container housing case  30 , the reject container left side plate  13 L abuts the sliding surface  56  of the claw portion  52 . 
     Moreover, when the reject container  13  is lowered, the hook member  48  rotates clockwise around the shaft  58  as shown in  FIG. 10B , while causing the sliding surface  56  to slide along the reject container left side plate  13 L. 
     At this time, at the spring  60 , the lower arm portion  60 L abuts the housing case left side plate  30 L, and further clockwise rotation is restricted. Due to the repulsive force that attempts to return the spring  60  to its natural state, the spring  60  applies urging force counterclockwise (in the direction of entering into the lock portion hole  62 ) to the claw portion  52 . 
     Then, when the bank clerk lowers the reject container  13  to the position where the reject container hole  64  faces the lock portion hole  62 , as shown in  FIG. 10C , the hook member  48  rotates counterclockwise, and the claw portion  52  hooks on the reject container hole  64 . Due thereto, the reject container  13  is set at a predetermined position in the reject container housing case  30 . 
     On the other hand, at the time when the reject container  13  is to be removed from the reject container housing case  30 , when the bank clerk pushes the operation section  54  downward, the lock portion  46  rotates clockwise in  FIGS. 10A  to C around the shaft  58 . Due thereto, the hooking of the claw portion  52  on the reject container hole  64  becomes disconnected. 
     In this state, due to the bank clerk grasping the handle  32  of the reject container  13  from above the reject container housing case  30  and pulling the handle  32  up, the reject container  13  is removed from the reject container housing case  30 . 
     By the way, in the state in which the reject container  13  is housed and locked in the reject container housing case  30 , and the reject container housing case  30  is attached to the unit housing that is in the pulled out state, when the bank clerk pulls the reject container  13  up, the reject container housing case  30  is brought-up together with the reject container  13 . Due thereto, as shown in  FIG. 7B , the hooking of the hook portions  35  on the unit housing front surface plate  18 F becomes disconnected. 
     In this state, when the bank clerk moves the reject container  13  forward, due to the reject container housing case  30  moving forward together with the reject container  13 , the catch-on portions  34  come out from the slit holes  36  as shown in  FIG. 7A . 
     Due thereto, the bank clerk can remove the reject container  13  and the reject container housing case  30  together from the unit housing  18 , merely by manipulating the reject container  13  that is locked to the reject container housing case  30 . 
     [1-5. Operation and Effects] 
     In the above-described structure, at the automatic teller machine  1 , the reject container housing case  30  is provided so as to be able to be attached to and removed from the front surface of the unit housing  18 . 
     Therefore, if there are limits on the surface area in front of the automatic teller machine  1  that is set, the bank clerk may make the length of the bank note storage section  15  in the front-rear direction shorter by removing the reject container housing case  30  from the unit housing  18 . Therefore, in the present exemplary embodiment, substantially the entire unit housing  18  may be pulled out from the housing  2  to the front. 
     Due thereto, at the automatic teller machine  1 , in particular, the storage containers  12  that are disposed at the deep side of the unit housing  18  may be easily removed from the unit housing  18 . 
     Further, due to the simple structure of the catch-on portions  34  being hooked on the slit holes  36  and the screw  42  with a knob portion being fastened, the bank clerk can easily attach and remove the reject container housing case  30  to and from the unit housing  18  without requiring a tool such as a screwdriver or the like. 
     Further, due to the simple structure of the hook member  48  being hooked on the reject container hole  64 , the bank clerk may easily install and remove the reject container  13  into and from the reject container housing case  30  without requiring a tool such as a screwdriver or the like. 
     By the way, for example, it can also be thought to make the length of the unit housing in the front-rear direction shorter by providing a hinge at either the left or right of the intermediate portion of the unit housing in the front-rear direction, and dividing the unit housing in two and rotating the unit housing with this hinge being the point of support. 
     However, in this case, in order to divide and rotate the unit housing that is very heavy, the structure becomes complex such as casters are provided beneath the divisional front portion of the unit housing, or the like, and the work of rotating the front portion of the heavy unit housing is required. 
     In contrast, in the automatic teller machine  1  in accordance with the present exemplary embodiment, by the simple structure of hooking the reject container housing case  30  on the unit housing  18 , the length of the bank note storage section  15  in the front-rear direction may be shortened by the extremely simple work of removing the reject container housing case  30  from the unit housing  18 . 
     In accordance with the above-described structure, the automatic teller machine  1  is provided with the housing  2  that has a predetermined space at the interior thereof and at which an opening portion is formed in at least one side surface thereof; the unit housing  18  that houses the storage containers  12 A to  12 E that store bank notes, and that can be accommodated within the housing  2 , and that is provided so as to be able to be pulled out along a pull out direction to the exterior of the housing  2  via the opening portion; and the reject container housing case  30  that is structured so as to be able to be attached to and removed from the unit housing  18  at the front side of the unit housing front surface plate  18 F that is at the distal end side in the pull out direction at the unit housing  18 , and that can house the reject container  13  that stores bank notes. 
     Due thereto, at the time of pulling the unit housing  18  out from the housing  2 , the space that is needed in front of the housing  2  can be reduced by removing the reject container housing case  30  from the unit housing  18 . 
     [2. Second Exemplary Embodiment] 
     An automatic teller machine  101  in accordance with a second exemplary embodiment is structured similarly to the automatic teller machine  1  in accordance with the first exemplary embodiment, except that a reject container  113  differs from the reject container  13 , as shown in  FIG. 11A  and  FIG. 11B  in which the same reference numerals are applied to portions corresponding to  FIG. 5A  and  FIG. 5B . 
     In the automatic teller machine  101  relating to the second exemplary embodiment, the reject container housing case  30  is omitted, and the reject container  113  is provided so as to be able to be attached to and removed from the unit housing  18  directly. 
     L-shaped (hook-shaped) catch-on portions  134  are formed so as to be directed rearward from the rear end portions near to the upper portions of a reject container left side plate  113 L and a reject container right side plate  113 R of the reject container  113 , at positions facing the slit holes  36  of the unit housing front surface plate  18 F. 
     In this structure, when the reject container  113  is to be attached to the unit housing  18 , by inserting the catch-on portions  134  along the horizontal direction into the slit holes  36 , and thereafter, lowering the reject container  113  along the vertical direction, the catch-on portions  134  fit-together with the slit holes  36 . 
     On the other hand, when the reject container  113  is to be removed from the unit housing  18 , first, the bank clerk pulls the unit housing  18 , to which the reject container  113  is attached, out to the front from the housing  2 . 
     Then, due to the bank clerk lifting the reject container  113  up along the vertical direction and thereafter pulling the reject container  113  forward, the catch-on portions  134  come out of the slit holes  36 , and the reject container  113  is removed from the unit housing  18 . 
     In this way, at the automatic teller machine  101 , as compared with the automatic teller machine  1 , the reject container housing case  30  is eliminated, and therefore, the structure may be made to be simpler. 
     [3. Other Exemplary Embodiments] 
     Note that the above-described first exemplary embodiment describes a case in which the one reject container  13  is housed in the reject container housing case  30  that is provided at the front surface of the unit housing  18 . 
     The present invention is not limited to this, and, as shown in  FIG. 12 , two reject containers  13 A and  13 B may be lined-up in the front-rear direction and housed in a reject container housing case  230  whose length in the front-rear direction is longer than that of the reject container housing case  30  ( FIG. 5A ,  FIG. 5B ). Further, three or more reject containers may be housed, and, in this case, it suffices to set the length of the reject container housing case in the front-rear direction to be a length that can house all of the reject containers that are to be housed. 
     Further the above-described second exemplary embodiment describes a case in which the one reject container  13  is provided so as to be able to be attached to and removed from the front surface of the unit housing  18 . 
     The present invention is not limited to this, and, as shown in  FIG. 13 , two reject containers  313 A and  313 B may be hooked on the front surface of the unit housing  18 . Further, a predetermined number, that is three or more, of reject containers may be hooked on the front surface of the unit housing  18 . 
     In this case, the reject container  313 B may be provided so as to be able to be attached to and removed from the reject container  313 A by forming slit holes  336  in the front surface of the reject container  313 A at positions facing catch-on portions  334 B of the reject container  313 B, and hooking these catch-on portions  334 B on the slit holes  336 . 
     Moreover, in the above-described exemplary embodiments, the reject container housing case  30  can be removed from the unit housing  18  merely by manipulating the reject container  13  that is locked in the reject container housing case  30 . However, the present invention is not limited to this. The reject container  13  may be removed from the reject container housing case  30  after the reject container housing case  30  is removed from the unit housing  18 , due to the bank clerk lifting-up the housing case bottom plate  30 B of the reject container housing case  30  from below. 
     Moreover, the above-described exemplary embodiments describe cases in which the reject container housing case  30  is removed from the unit housing  18  by lifting the reject container housing case  30  up, and thereafter, moving the reject container housing case  30  forward. 
     The present invention is not limited to this, and, for example, there may be a structure in which the reject container housing case  30  is screwed to the unit housing  18  at two places that are above and below, and the bank clerk removes the reject container housing case  30  from the unit housing  18  by moving the reject container housing case  30  toward the near side. 
     Moreover the above-described exemplary embodiments describe cases in which the lock portion  46  is provided at the housing case left side plate  30 L. However, the present invention is not limited to this. For example, the lock portion  46  may be provided at any of various places, such as at the housing case right side plate  30 R or the like. 
     Moreover, the above-described exemplary embodiments describe cases in which the one lock portion  46  is provided at the reject container housing case  30 , but the present invention is not limited to this, and an arbitrary number of two or more lock portions  46  may be provided. If a large number of the lock portions  46  are provided, the labor required at the time when the reject container  13  is inserted into or removed from the reject container housing case  30  increases, but the reject container  13  may be fixed more stably in the reject container housing case  30 . 
     Moreover, the above-described exemplary embodiments describe cases in which the reject container housing case  30  is joined to the unit housing  18  by hooking the L-shaped catch-on portions  34  on the slit holes  36 . The present invention is not limited to this. The reject container housing case  30  and the unit housing  18  may be joined by any of various mechanisms such as, for example, joining by a lock mechanism having screw and a rotatable knob portion, or the like. 
     Moreover, the above-described exemplary embodiments describe cases in which the reject container  13  is joined to the reject container housing case  30  by hooking the lock portion  46 , that has the claw portion  52 , on the reject container hole  64 . The present invention is not limited to this. The reject container  13  and the reject container housing case  30  may be joined by any of various mechanisms such as, for example, joining by a lock mechanism having screw and a rotatable knob portion, or the like. 
     Moreover, in the above-described exemplary embodiments, the screw portion  42 A of the screw  42  having a knob portion has a length, in the front-rear direction, that is sufficiently longer than the plate thickness T of the unit housing front surface plate  18 F. The present invention is not limited to this. The screw  42  having a knob portion may be made to be difficult to be removed from the unit housing front surface plate  18 F by any of various mechanisms such as, for example, forming the rear end of the screw portion  42 A in a shape that prevents coming out, or the like. 
     Moreover, the above-described exemplary embodiments describe cases in which the present invention is applied to the reject container housing case  30  that houses the reject container  13  and that can be removed from the unit housing  18  that houses the plural storage containers  12 . 
     The present invention is not limited to this. For example, the present invention may be applied to a drawer that houses a storage container that is provided so as to be able to be removed from the drawer that is pulled out from an automatic teller machine, and that stores bank notes that are used for various applications, such as bank notes used exclusively for withdrawal, bank notes used exclusively for depositing, bank notes to be replenished, collected bank notes, bank notes to be recycled, and the like. 
     Further, the objects housed in the unit housing are not limited to storage containers, and, in short, it suffices to house objects that can be removed by pulling the unit housing  18  out from the housing  2 . 
     Moreover, the above-described exemplary embodiments describe cases in which, by moving the unit housing  18  toward the front side of the housing  2 , the unit housing  18  is set in the pulled out state in which most of the unit housing  18  is pulled out to the exterior of the housing  2 . 
     The present invention is not limited to this, and, for example, the unit housing  18  may be set in the pulled out state by being moved toward the rear side of the housing  2 . 
     Moreover, the above-described first exemplary embodiment describes a case in which the pull out lever  20  is provided at the unit housing front surface plate  18 F. The present invention is not limited to this, and a pull out lever may be provided at the housing case front surface plate  30 F. 
     In this case, it suffices to increase the strength of the reject container housing case  30  to the extent that the reject container housing case  30  does not deform when the unit housing  18  that is heavy is pulled to the front via the reject container housing case  30 . Due thereto, the position of the pull out lever can be set further toward the front side, and therefore, the workability may be improved. 
     Moreover, in the above-described second exemplary embodiment, a pull out lever may be provided at a reject container front surface plate  113 F. In this case as well, the position of the pull out lever can be set further toward the front side, and therefore, the workability can be improved. 
     Moreover, the number of reject bank notes that can be stored may be changed by changing the size of the reject container  13  per store in which the automatic teller machine is disposed. At this time, it suffices to form the reject container housing case  30  to a size such that it can house the reject container  13 . 
     Moreover, the above-described exemplary embodiments describe cases in which, at the automatic teller machine  1  that carries out transactions of cash such as bank notes or the like, the respective processings such as the conveying processing, the storing processing, and the like are carried out on bank notes that serve as the media. 
     However, the present invention is not limited to this, and may be applied to any of various devices that carry out respective processings such as conveying processing, storing processing and the like on thin, paper-like media such as, for example, gift certificates, cash vouchers, admission tickets, or the like. 
     Moreover, the above-described exemplary embodiments describe cases in which the automatic teller machine  1  that serves as the media processing device is structured by the housing  2  that serves as the housing, the unit housing  18  that serves as the drawer, and the reject container housing case  30  or the reject container  13  that serves as the media storage section. 
     However, the present invention is not limited to this, and the media processing device may be structured by a housing, a drawer and a media storage section of any of various other structures.
