The first transfer device 310 may comprise a first transfer roller 312 and a second transfer roller 318 that transfers the medium with the first transfer roller 312.
A sheet roller 314 having a wing 316 for assisting stacking of the medium is connected to a shaft of any one of the first transfer roller 312 and the second transfer roller 318. At this time, a plurality of the wings 316 is entirely disposed on the periphery of the sheet roller 314 with a predetermined distance spaced apart with each other or a plurality of the wings 316 is partially disposed on the periphery of the sheet roller 314 with a predetermined distance spaced apart with each other.
In FIG. 3, it is illustrated that the sheet roller 314 is connected to shaft of the first transfer roller 12 as an example.
The temporary stacking unit 30 may further comprise a second transfer device 320 for transfer the temporary stacking medium one by one.
The second transfer device 320 may comprise a pick-up roller 322 for picking up the temporary stacking medium, a feed roller 324 for transfer the picked up medium, and a gate roller 326 that is positioned opposite to the feed roller 324.
The gate roller 326 may maintain in a state rotating in the same direction as that of the feed roller 324 or a stationary state.
The temporary stacking unit 30 may further comprise a first guide 340 and a second guide 370 that are movable in a stacking space 303.
The first guide 340 and the second guide 370 may be moved in the stacking space 303 by means of independent movement means, respectively.
The first guide 340 may guide the stacking operation of the medium in a stacking process of the medium. Accordingly, the first guide 340 is referred to as a stacking guide.
The second guide 370 can support the medium stacked on the stacking surface 302 during the stacking process of the medium in order not to fall down the medium. Accordingly, the second guide 370 is referred to as a supporting guide.
The first guide 340 may comprise a first plate 342 and a second plate 350 that is rotatably connected to the first plate 342.
The second plate 350 may be rotatably connected to the first plate 342 by means of the hinge shaft 354, and may be folded or overlapped with the first plate 342.
The first guide 340 may further comprise an elastic member 356 that supplies a rotating force for rotating the second plate 350 in a direction overlapped with the first plate 342 to the second plate 350. A vibration by a rotation of the second plate 350 may be prevented in the case of the pick-up of medium by means of the elastic member 356.
In addition, the first guide 340 may further comprise a fixing member that fixes the second plate 350 and the first plate 342 in a state where the second plate 350 is overlapped with the first plate 342. A vibration by a rotation of the second plate 350 may be prevented in the case of the pick-up of medium by means of the fixing member.
The elastic member 356 may be a torsion spring as an example. The torsion spring is disposed around the hinge shaft 354.
In this specification, the state as in the FIG. 4 is referred to as a state where the second plate 350 is overlapped with the first plate 342. The state as in the FIG. 5 is referred to as a state where the second plate 350 is rotated about the first plate 342.
A receiving portion 344 that receives the second plate 350 is provided in the first plate 342 in order to prevent a thickness of the first guide 340 from increasing in a state where the second plate 350 is overlapped with the first plate 342. At this time, the thickness of the first guide 340 may be same as the thickness of the first plate 342 in a state where the second plate 350 is received in the receiving portion 344.
A guide surface 351 of the second plate 350 may be positioned on the same plane as the front surface 342a (surface facing the second guide 370) of the first plate 342 or may be positioned at the rear side of the front surface 342a of the first plate 342 in a state where the second plate 350 is overlapped with the first plate 342.
The first plate 342 may further comprise a projecting portion 346 for passing through the second plate 250. The friction portion 348 may be provided at least one surface of the projecting portion 346. The friction portion 348 may be formed of a rubber material as an example. As another example, it is possible for all the projecting portions 346 to be formed of a rubber material, in this case, a coupling portion is provided in the first plate 342 so that the projecting portion 346 is coupled to the first plate 342. 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 302a 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.
