As another example, the projecting portion  346  may be omitted and a groove (or a hole) in which a portion of the pick-up roller  322  is received may be formed in the first plate  342 . 
     The friction plate  348  may pass through the second plate  350  and may be in contact with the medium in a separation process of the medium. 
     The second plate  350  may comprise a through hole  352  through which the projecting portion  346  is passed. At this time, the through hole  352  may be larger than the projecting portion  346  so that the second plate  350  and the projecting portion  346  are not interfere with each other in a rotation process of the second plate  350 . 
     The projecting portion  346  having the friction portion  348  may be projected to the side of the second guide  370  on the guide surface  351  of the second plate  350  through the second plate  350  in a state where the second plate  350  is overlapped with the first plate  342 . On the other hand, when the second plate  350  is rotated, at least a portion of the projecting portion  346  is removed from the through hole  352  and thus the projecting portion  346  is not projected from the second plate  350 . In other words, when the second plate  350  is rotated, the projecting portion  346  is positioned at the rear side of the guide surface  351 . 
     As another example, the friction portion  348  is provided on the second plate  350  and is projected form the guide surface  351  in a state where the second plate  350  is overlapped with the first plate  342 . When the second plate  350  is rotated, the friction portion  348  may be configured to move so that the friction portion  348  is positioned at the rear side of the guide surface  351 . As an example, it is possible to be configured that the friction portion  348  is rotatably provided to the second plate  350  and a link is connected to the friction portion  348 . 
     The guide surface  351  for guiding the medium in the second plate  350  may be smoothly formed for stably transfer guide of the medium. As an example, the friction coefficient of the guide surface  351  is lower than the friction coefficient of the friction portion  348 . 
     It is possible that a plurality of the ribs (not shown) is provided on the guide surface  351  in order to be in line contact with the temporary stacking medium. 
     A slot  358  may be provided in the lower side portion of the second plate  350  for preventing from being interfered with the wing  316  of the seat roller  314 . 
     The temporary stacking unit  30  may further comprise a rotating guide  360  for rotating the second plate  350  about the first plate  342 . 
     The rotating guide  360  may be disposed at the rear side of the first guide  340  and may be fixed to a frame (not shown). 
     The rotating guide  360  is capable of stopping the first plate  342  and rotating the second plate  350  about the first plate  342  when the first guide  340  is moved to the side of the rotating guide  360 . 
     The rotating guide  360  may further comprise a push portion  362  that pushes the second plate  350  so that the second plate  350  is rotated about the first plate  342 . 
     The push portion  362  may pass through the first plate  342 , and a through opening  345  through which the push portion  362  is passed is provided on the first plate  342 . The push portion  362  may be spaced apart from the hinge shaft  354 . In addition, an operable member (not shown, roller or the like, as an example) that may be capable of relative motion with the second plate  359  without the wear of the push portion  362  is provided on the end portion of the push portion  362  when the second plate  350  is pushed and thus rotates about the first plate  342 . 
     The push portion  362  is capable of contacting the second plate  350  through the through opening  345  of the first plate  342 , during a process in which the first guide  340  moves toward the rotating guide  360  (in a right direction based on the  FIG. 3 ). 
     In this state, the second plate  350  is rotated about the first plate  342  during the process in which the second plate  350  moves with the first plate  342  when the first guide  340  is further moved in a right direction. Subsequently, the first guide  340  stops when first plate  342  is in contact with the rotating guide  360 . 
     At this time, the rotation angle of the second plate  350  may be adjusted according to a length of the push portion  362  and the position of the rotating guide  360 . 
     As another example, it is possible that the first guide  340  does not stop as the first guide  340  is in contact with the rotating guide  360  and the first guide  340  stops by detecting the number of revolutions of the motor for moving the first guide  340 . 
     On the other hands, the first guide  340  may move in the substantially parallel direction to the stocking surface  302  and a guide groove  302   a  may be provided in the stocking surface  302  for guiding the movement of the first guide  340 . 
     In addition, the temporary stacking unit  30  may further comprise a damper  380  on which the medium passing through the first transfer roller  312  and the second transfer roller  318  is collided. 
     At this time, a portion of the second plate  350  is positioned lower than the stocking surface  302  and the remaining portion of the second plate  350  is overlapped with the damper  380  in a state where the second plate  350  is rotated so that temporary stacking medium is prevented from being caught into the second plate  350 . Although it is not illustrated, a groove or slot may be formed on the damper  380  for preventing from being interfered with the second plate  350 . 
       FIG. 6  is a view illustrating a process during which the medium is temporarily stacked according to an embodiment, and  FIG. 7  is a view illustrating a process in which the temporary stacking medium is separated according to an embodiment. 
     First, referring to  FIG. 2  and  FIG. 6 , the medium may be accepted into the medium receiving space of the medium depositing and withdrawing unit  13 , for deposit transactions for the medium. The medium accepted into the medium receiving space may be separated one by one by means of the medium separation device. The medium separated one by one passes through the discrimination unit  20 . 
     The temporary stacking medium M determined as a normal medium of the mediums that passes through the discrimination unit  20  is transferred along the first path  304  and is stacked to the stacking space  303  by means of the first transfer device  310 . 
     The second guide  370  and the first guide  340  may position at the stacking standby position for the temporary stacking medium. 
     In the stacking standby position, the second plate  350  maintains at the state rotated about the first plate  342 . At this time, the second plate  350  is disposed to be inclined at a predetermined angle relative to the vertical line and thus guides the temporary stacking medium M which is transferred by means of the first transfer device  310 . The angle between the second plate  350  and the stacking surface  302  may be the acute angle that is smaller than 90 degree. 
     At this time, since the friction portion  348  that is provided on the first plate  342  is not projected from the second plate  350 , the stacking defect by the temporary stacking medium M being in contact with or is collided with the friction member  348  is generated may be prevented. 
     The second guide  370  may move in the direction away from the first guide  340  (in a left direction in  FIG. 6 ) when the number of the temporary stacking medium M that is stacked in the stacking space  303  is increased. 
     The second guide  370  and the first guide  340  moves into the separation standby position as in the  FIG. 7  in order to separate the temporary stacking medium M, when temporarily stacking of the temporary stacking medium M in the stacking space  303  is completed. 
     The second guide  370  and the first guide  340  may move toward the second transfer device  320  (toward the left direction on the drawing) so that the second guide  370  and the first guide  340  is moved from the stacking standby position to the separation standby position. 
     Since the second guide  370  and the first guide  340  moves in a state where the temporary stacking medium M is positioned between the second guide  370  and the first guide  340 , the second guide  370  and the first guide  340  may be moved at a same speed with each other in order to prevent from falling down the temporary stacking medium M. 
     The second plate  350  is overlapped with the first plate  342  by an elastic force of the elastic member  356  by the first guide  340  being away from the rotating guide  360  during the process in which the first guide  340  moves to the separation standby position. 
     The friction portion  348  is in contact with the temporary stacking medium (the medium that is disposed on the outermost right side on the drawing) which is most lastly introduced into the stacking space  303  of the temporary stacking mediums M by the projecting portion  346  having the friction portion  348  passing through the second plate  350  during the process in which the second plate  350  is overlapped with the first plate  342 . 
     The second plate  350  may be substantially perpendicular to the stacking surface  302  in a state that the second plate  350  is overlapped with the first plate  342 . 
     The temporary stacking medium M may be spaced apart with the second guide  370  moved to the separation standby position being not interfered with the pick-up roller  322 . 
     On the other hand, in a state where the guides  340  and  370  move to the separation standby position, the information of the medium being completed discrimination and then stacked to temporary stacking unit  30  and the information of the medium returned to the medium depositing and withdrawing unit  13  may be displayed to an user interface  11 . Subsequently, deposit confirmation command or deposit cancellation command about medium stacked to the temporary stacking unit  30  through the user interface  11  may be input. 
     The medium stacked to the temporary stacking unit  30  may be separated and transferred by the second transfer device  320  and may be stored in the medium storage box  40  through the second path  306  when the deposit confirmation command is input through the user interface H. 
     The first guide  340  may press the temporary stacking medium M to the side of the pick-up roller  322  in the separation process of the temporary stacking medium M. 
     The pick-up roller  322  may have a high friction material of the pick-up portion  323  on a portion of the circumferential perimeter thereof. At this time, the pick-up portion  323  may be formed of a rubber material as an example. 
     The temporary stacking medium M may be picked up by the friction force between the temporary stacking medium M and the pick-up portion  323  in the case of the pick-up portion  323  being in contact with the temporary stacking medium M during the rotating process of the pick-up roller  322 . 
     At this time, the friction force is increased in the case of the pick-up portion  323  being in contact with the temporary stacking medium M and phenomenon that the medium M contacted with or positioned adjacent to the first guide  340  of the mediums M by increasing this friction force is rotated may be generated. It is likely to cause a jam during the transfer of the medium by generating skew in a case where a portion of the medium M is separated from the rotated state. 
     However, according to the present embodiment, since the most lastly positioned medium of the temporary stacking mediums M is in contact with the friction portion  348  in a state of supporting by the first guide  340 , there is an advantage that rotation of the most lastly positioned medium of the temporary stacking mediums M is prevented. 
     At this time, the friction portion  348  may be disposed to face with the pick-up portion  323  when the pick-up portion  323  is in contact with the temporary stacking medium M. Alternatively, it is possible that a plurality of the friction portion  348  are disposed to be spaced apart in a horizontal direction and the area between two friction portions  348  adjacent to each other and the pick-up portion  323  is disposed to be faced with each other. 
     On the other hand, the hinge shaft  354  of the second plate  350  is positioned at the position lower or equal than the point at which the pick-up portion  323  is in contact with the temporary stacking medium M. 
     The direction in which the second plate  350  is capable of rotating is a direction approaching the pick-up roller  322  (in the counter-clockwise direction on the drawing). Meanwhile, in a case where the hinge shaft  354  is positioned at the higher height than the point at which the pick-up portion  323  is in contact with the temporary stacking medium M, during the process in which the first guide  340  pushes the temporary stacking medium M and during the process in which the pick-up roller  322  picks up the temporary stacking medium  340 , a force applies to the underside of the hinge shaft  354  and thus the second plate  350  is about to rotate, and in this case there is a problem that pick-up defects is generated by the pressing force of the temporary stacking medium M being changed. However, according to the present invention, the generation of such a problem may be prevented. 
     However, in a case where the fixing means for fixing the position of the second plate  350  is provided with the second plate  350  being overlapped with the first plate  342 , it is possible that the hinge shaft  354  of the second plate  350  is positioned at the higher height than point at which the pick-up portion  323  is in contact with the temporary stacking medium M. 
     According to the present embodiment, since the first guide serves as a stacking guide in the case of stacking the medium and serves as a pressing portion that presses the medium in the case of separating the medium, the number of the guide provided in the temporary stacking unit may be reduced and thus the structure of the temporary stacking unit is simplified. 
     Further, since the second plate constituting the first guide is rotated about the first plate or overlapped with the first plate without a separate driving means, increasing in cost and complication of the structure according to arrangement of the driving means may be prevented. 
     In addition, the friction portion of the first guide may be in contact with the medium at the separation of the medium and thus the rotation of the separating non-target medium is prevented. 
       FIG. 8  is a view illustrating a state where a second plate is rotated in a first guide according to another embodiment,  FIG. 9  is a view illustrating a state where the second plate is overlapped with the first guide according to another embodiment, and  FIG. 10  is a perspective view illustrating a rotating guide according to another embodiment. 
     The present embodiment is the same as the previous embodiment except for the structures of the first guide and a rotating guide. Therefore, hereinafter, only the characteristic parts of this embodiment will be described, and the same parts as those of the previous embodiment will be quoted the contents of the previous embodiment. 
     Referring to  FIG. 8  to  FIG. 10 , according to the present embodiment, the first guide  440  may comprise a first plate  442  and a second plate  450  that is rotatably connected to the first plate  442 . 
     A first sensor (not shown) for detecting whether or not the medium is present in the stacking space  303  and a second sensor  465  for detecting whether or not the medium is present in falling down state in the stacking surface  302  in the stacking space  303  are provided in the temporary stacking unit  30 . 
     Each of the sensor  465  may have a light emitting unit and light receiving unit. When the light emitted from the light emitting unit of the first sensor does not reach the light receiving unit, it may be determined that the medium is present in the stacking space  303 . Further, when the light emitted from the light emitting unit of the second sensor  465  does not reach the light receiving unit, it is determined that the medium is present in falling down state in the stacking space  303 . However, in the present embodiment, it is not limited regarding to a sensing method, the whether or not the medium is present and the medium is in the falling down state may be detected using various methods. 
     The first sensor may be disposed to be arranged in the vertical direction as a plurality of the sensor. However, it is not limited to such a method. 
     A first opening  443  and a second opening  444  for passing through the light emitted from the light emitting unit of the first sensor may be comprise in the first guide  442 . The first opening  443  and the second opening  444  is disposed to be spaced apart in the vertical direction. 
     A third opening  451  through which the light passing through the first opening  443  is passed and the fourth opening  452  through which the light passing through the second opening  444  is passed may be comprised in the second guide  450 . 
     At this time, the light emitted from the light emitting unit of the first sensor can be pass through the first opening  443  and the second opening  444  and then can be pass through the third opening  451  and the fourth opening  452  even in a state where the second plate  450  is overlapped with the first plate  442 , as well as the light emitted from the light emitting unit of the first sensor can be pass through the first opening  443  and the second opening  444  and then can be pass through the third opening  451  and the fourth opening  452  even in a state where the second plate  450  is rotated about the first plate  442 . To this end, the third opening  451  and the fourth opening  452  may be formed to be lengthened in the vertical direction. 
     A rotating guide  460  may further comprise in the temporary stacking unit  30 . The second sensor  465  may be installed in the rotating guide  460  of the present embodiment. At this time, an inclined installing portion  464  is provided in the rotating guide  460  and the second sensor  465  is stalled in the installing portion  464 . 
     The light emitted from the light emitting unit of the second sensor  465  may pass through the first opening  443 . A fifth opening  453  through which the light emitted from the light emitting unit of the second sensor  465  passes is provided in the second plate  450 . 
     The second sensor  465  may detect the falling down of medium in the stacking process of the medium and the light emitted from the light emitting unit of the second sensor  465  is capable of passing through the first opening  443  and the fifth opening  453  in a state where the second plate  450  is rotated about the first plate  442 . 
     The rotating guide  460  may comprise a push portion  462  that pushes the second plate  450  so that the second plate  450  is rotated about the first plate  442 . At this time, a sliding member ( 463 , roller or the like, for example) that may be capable of sliding with the second plate  450  without the wear of the push portion  462  is provided on the end portion of the push portion  462  when the second plate  450  is pushed and thus rotates about the first plate  442 . 
     A groove (or a hole)  455  in which a portion of the pick-up roller  332  is received may be formed in the second plate  450 . In a case where the groove (or hole) for shielding the pick-up roller  322  is formed on the second plate  450 , a portion of the medium lastly positioned is received in the groove (or hole) for shielding and thus curl is generated in the medium. In this case, the deviation of the friction force between a plurality of the portions facing the pick-up roller  322  in the medium lastly positioned and the first guide  440  is reduced and thus the lastly positioned medium of the mediums M in the pick-up process of the medium M is prevented from being rotated. 
     According to the embodiment described above, it is described that the temporary stacking medium for stacking in the first path is transferred and the temporary stacking medium separated in the second path is transferred. However, alternatively, it is possible to transfer the temporary stacking medium for stacking in the first path as well as to transfer the separated temporary stacking medium. In this case, the first transfer device may be omitted, and the second guide may have the same or similar structure as the structure of the first guide described above. 
     However, in this case, the second plate which is a guide rotated in the second guide may be configured to be rotated in the clockwise direction on the drawings about the first plate and thus to guide the stacking of the medium.
