Furthermore, a fall prevention mechanism (a fall prevention lever 11n, a top plate guide 11o, a spring 11p) is provided above the separation / stacking guide 11f.

  The separation / stacking guide 11f is a guide for guiding the paper sheets on the paper sheet transport path 11k to the stacking space 11s and guiding the paper sheets from the stacking space 11s to the paper sheet transport path 11k. The separation / stacking guide 11f is formed in a U-shaped cross-sectional shape in plan view, and a surface on the stacking space side of the U-shaped cross-section in plan view is used as a sheet guide surface. The separation / accumulation guide 11f is configured to pivot in the direction of arrow B with the lower pivot shaft 13a as the pivot center.

  More specifically, when collecting paper sheets, the separation / stacking guide 11f forms a space in which the paper sheet guide surface extends along the extension of the paper sheet traveling direction at the take-in and discharge port 11j of the paper sheet transport path 11k. It pivots to the position 11fa when the paper sheets function as the position.

Is guided to the accumulation space 11s.

  Further, at the time of paper sheet separation, the separation / stacking guide 11f is retracted from the paper sheet guide surface until the pickup roller 12p is exposed to the stacking space side, and the paper sheet is transported from the stacking space 11s to the paper sheet transport path 11k. It pivots to a paper sheet separation position 11fb that functions as a guiding position for guidance. The paper sheet separation position 11fb is behind the apparatus than the paper sheet separation position 11fa.

  Further, the separation / stacking guide 11f at the time of loading / unloading paper sheets forms a space that allows the loading / unloading of paper sheets, so that the paper sheets that have fallen to the stacking space 11s side from the position 11fa at the time of stacking paper sheets. It pivots to the position 11fc at the time of class insertion / release. The paper sheet loading / unloading position 11fc is in front of the apparatus than the paper sheet separating position 11fa. That is, the separation / stacking guide 11f includes a paper sheet stacking position (first position) 11fa, a paper sheet separating position (second position) 11fb, and a paper sheet loading / unloading position (third position). ) It is configured to be displaced at three locations of 11fc.

  The backup roller 11g rotates following the feed roller 12f so as to convey the paper sheet by sandwiching the paper sheet between the feed roller 12f opposed to the paper sheet conveyance path 11k. It is configured.

  The brush roller 11h is a roller that is arranged on the same axis as the central axis 13b of the gate roller 12g, and that is flexible and has a sheet-like pushing member formed in an inverted J shape radially arranged in at least three directions. . The pushing members are desirably arranged radially in four directions.

  The paper sheet transport path 11k communicates with the transport path 50a and is configured to allow passage of paper sheets to be separated and stacked. Note that a feed roller 12f and a gate roller 12g are provided on both sides of the paper sheet transport path 11k, and an end on the accumulation space 11s side serves as a take-out / discharge port 11j to the accumulation space 11s.

  The travel restricting means 11l disposed above the separation / stacking guide 11f is configured to be restrained at an upper position of the sheets stacked in the stacking space 11s. The travel restricting means 11l forms two recesses 13c by arranging two hook-shaped blade-shaped portions having projecting pieces whose tips protrude in the counterclockwise direction on the same axis. Further, the travel restricting means 11l is configured to be rotationally driven in the direction of arrow C around the central axis 13d by a motor for travel restricting means.

  The fall prevention lever 11n is configured to pivot in the direction of arrow D about a center axis (not shown). Further, the lock link mechanism 11q has a structure that moves up and down around a central axis 13e by an actuator (not shown). Detailed operations of these mechanisms will be described later.

  The feed roller 12f is driven by a feed roller drive motor, sandwiches the paper sheets with the backup roller 11g opposed across the paper sheet conveyance path 11k, and conveys the accumulated paper sheets to the accumulation space 11s. The paper sheets to be separated are sent to the transport path 50a via the paper sheet transport path 11k.

  The gate roller 12g is a roller configured to rotate in the sheet stacking direction around the central shaft 13b and not in the feeding direction by using a one-way clutch or the like.

  With these structures, the separation / stacking mechanism can separate and reliably release the sheets stacked in the stacking space 11s one by one during the separation, and also reliably the sheets that have passed through the sheet transport path 11k. It is possible to accumulate in the accumulation space 11s in a standing state.

  Next, the fall-down prevention mechanism disposed above the separation / stacking guide 11f will be described with reference to a schematic layout diagram of the separation / stacking guide 11f shown in FIG.

  As shown in the front view of the separation / accumulation guide 11f in FIG. 6A, the fall prevention levers 11n and 11t are arranged above the separation / accumulation guide 11f, and the center of the separation / accumulation guide 11f is advanced. It is arrange | positioned in the two places of the both outer sides of the control means 11l.

  Further, as shown in FIG. 6B (EE ′ cross-sectional view), the fall prevention mechanism includes a fall prevention lever 11n, a spring 11p, a stopper from the separation / stacking guide 11f, and a top plate guide 11o. It is composed of The fall-preventing lever 11n provided at the center of the separation / stacking guide 11f is retracted to a position where it is not exposed from the separation / stacking guide 11f and overlaps with the separation / stacking guide 11f. The shape extends in the direction. Further, as shown in FIG. 6C (FF ′ cross-sectional view), the fall prevention levers 11t provided on both outer sides of the separation / stacking guide 11f are retracted to a position where they are not exposed from the separation / stacking guide 11f. In order to overlap with the separation / accumulation guide 11f, the separation / accumulation guide 11f always overlaps with the separation / accumulation guide 11f. A hook-like shape (hook portion) 13f is formed at the upper ends of the fall-preventing levers 11n and 11t.

  The fall prevention mechanism is configured such that the fall prevention levers 11n and 11t protrude from the separation / accumulation guide 11f around the central shaft 13g by the urging of the spring 11p attached to the fall prevention levers 11n and 11t, and the separation / accumulation guide 11f. It is a mechanism that hides in an unexposed position.

  The top plate guide 11o is provided on the top plate 11d, and is provided for each of the fall prevention levers 11n and 11t (total of three locations). Moreover, the top plate guide 11o is provided with a hole, and the fall prevention levers 11n and 11t are always overlapped with the hole. Further, the top plate guide 11o is formed with a hook-shaped protrusion 13h. With such a configuration, the separation / stacking guide 11f pivots to the paper loading / unloading position 11fc, so that the hook portions 13f of the fall prevention levers 11n and 11t and the hook portion 13h of the top plate guide 11o are connected. The levers 11n and 11t protrude from the catching and separating / accumulating guide 11f.

  In addition, since the plurality of hook-shaped protrusions 13h of the top plate guide 11o are arranged at the same position in the front-rear direction of the apparatus, the fall prevention levers 11n and 11t protrude at the same timing.

  The center falling prevention lever 11n has a protrusion 13i that overlaps with a groove formed in the floor plate 11a when protruding.

  Next, the position restricting means of the separation / accumulation guide 11f will be described with reference to the explanatory views shown in FIGS. As described above, the separation / stacking mechanism includes the lock link mechanism 11q as a position restricting means for the separation / stacking guide 11f, and the separation / stacking guide 11f is a spring (elastic member) 11r attached to the separation / stacking guide 11f. Due to the biasing force, the structure is always tilted in the accumulation direction (clockwise direction) around the pivot shaft 13a. The separation / stacking guide 11f has a structure that operates in conjunction with the operation of the push plate 11c. The lock link mechanism 11q is a structure that moves in the vertical direction about the central axis 13e of the lock link mechanism 11q by an actuator (not shown).

  As shown in FIG. 7A, when the pressing plate 11c is moved in the apparatus rearward direction 13aa, the separation / accumulation guide 11f is pushed by the pressing plate 11c or the accumulated paper sheets P, thereby the separation / accumulation guide. 11f operates to a paper sheet separation position 11fb. During the operation of the separation / accumulation guide 11f, the lock link mechanism 11q moves upward.

  On the other hand, as shown in FIG. 7B, when the push plate 11c is moved in the apparatus front direction 13ab, the separation / stacking guide 11f is tilted by the attached spring 11r and operates in the stacking direction of the paper sheets. Further, when the separation / stacking guide 11f is held at the paper sheet stacking position 11fa, the position of the separation / stacking guide 11f is confirmed by a sensor (not shown) to confirm that the position of the separation / stacking guide 11f is the paper stacking position 11fa. By moving the link mechanism 11q downward, the separation / stacking guide 11f can be held in a state of being regulated at the paper sheet stacking position 11fa.

  Further, as shown in FIG. 7C, by lowering the lock link mechanism 11q, the separation / accumulation guide 11f further falls in the accumulation direction. When the separation / stacking guide 11f further falls in the stacking direction, it pivots to the paper sheet loading / unloading position 11fc, and the hook portion 13g of the fall-preventing lever 11n and the hook portion 13h of the top plate guide 11o are hooked. In this configuration, the fall-preventing lever 11n protrudes from the separation / stacking guide 11f. Further, when the separation / stacking guide 11f is held at the paper sheet loading / unloading position 11fc, the separation / stacking guide 11f may be held at the paper sheet loading / unloading position 11fc by lowering the lock link mechanism 11q. it can. Accordingly, the fall prevention lever 11n does not protrude from the separation / stacking guide 11f at the paper sheet stacking position 11fa and the paper sheet separating position 11fb.

  Next, an accumulation process for accumulating paper sheets at the deposit / withdrawal port 10 of the paper sheet handling apparatus 1 will be described. FIG. 8 is an explanatory diagram of the separation / accumulation mechanism in the accumulation state in this embodiment. With the separation / stacking guide 11f of the separation / stacking mechanism regulated by the lock link mechanism 11q at the sheet stacking position 11fa, the feed roller 12f and the gate roller 12g disposed on both sides of the sheet transport path 11k Is rotated, and the paper sheet P that has passed through the paper sheet discriminating unit 20 is conveyed to the accumulation space 11s. At this time, the paper sheet P is conveyed in a standing state along the paper sheet guide surface of the separation / stacking guide 11f.

  In order to prevent the paper sheet that has passed through the paper sheet transport path 11k and released from the clamping force of the feed roller 12f and the gate roller 12g against the paper sheet P taken in from the outside from colliding with the subsequent paper sheet. The brush roller 11h is rotated from the nipping point between the feed roller 12f and the gate roller 12g.

  The paper sheets P accumulated in the accumulating space 11s and removed from the nipping between the feed roller 12f and the gate roller 12g collide with the recess 13c of the advancing direction restricting means 11l at the leading end in the advancing direction and stop. By performing the above operations continuously, the paper sheets P are accumulated. The accumulated paper sheets P are moved in the direction away from the separation / accumulation guide 11f (that is, the apparatus front direction 13ab) by the push plate 11c and the bottom belt 11b.

  During the stacking operation, the fall prevention lever 11n is retracted to a position where it is not exposed from the separation / stacking guide 11f so as not to disturb the stacking operation of the paper sheets P.

  Next, an operation for storing the paper sheets inserted into the deposit / withdrawal port 10 and an operation for discharging the accumulated paper sheets to the user will be described. FIG. 9 is a side view of the separation / stacking mechanism when a paper sheet is loaded and when a paper sheet is delivered in this embodiment.

  As shown in FIG. 9A, when the paper sheet P is put in the stacking space 11s in the direction of arrow G, the push plate 11c is disposed at the most retracted position, and the separation / stacking guide 11f is the paper sheet. This is a state in which the lever 11n of the separation / accumulation guide 11f protrudes from the position 11fc at the time of class insertion / discharge. At this time, the space formed by the push plate 11c and the fall-preventing lever 11n allows the paper sheets P to be put inside, and allows the paper sheets P to be stacked in a standing state. A simple space. Further, as shown in FIG. 9B, even when a small number of paper sheets P are put in the accumulating space 11s in the direction of arrow G, the paper sheets P are stacked in a standing state. Is possible.

  As shown in FIG. 6 (b), the center-falling prevention lever 11n has a protruding shape 13i that overlaps with a groove formed on the floor plate 11a, and has a structure that overlaps with the floor plate 11a. The paper sheet P does not enter the separation / stacking mechanism when the paper sheet is loaded.

  Further, as shown in FIG. 9C, when the paper sheet P can be taken out in the arrow H direction (that is, when the paper sheet is delivered), the pressing plate 11C moves in the apparatus front direction 13ab. As a result, the fall prevention lever 11n comes out in front of the apparatus, so that the movement of the paper sheet P can be restricted and the paper sheet P can be delivered to the staff so that the paper sheet P does not fall down. It becomes. At this time, the progress restricting means 11l rotates to a position that does not hinder the insertion of the paper sheets and the delivery of the paper sheets.

  Next, the operation in the case of separating the paper sheets put into the deposit / withdrawal port 10 will be described. FIG. 10 is a side view of the separation / stacking mechanism in the separated state. When separating the paper sheets, the pressing plate 11c is driven in the direction of the arrow 13aa as a preparatory operation to press the paper sheets against the separation / stacking guide 11f. At this time, when the separation / stacking guide 11f is pushed by the push plate 11c or the stacked paper sheet P, the fall prevention lever 11n protruding from the separation / stacking guide 11f is retracted to a position where it is not exposed. Further, since the separation / stacking guide 11f moves to the paper sheet separation position 11fb, the pickup roller 12p is exposed from the paper sheet guide surface, and the pickup roller 12p contacts the paper sheet P.

  Thereafter, the pickup roller 12p is rotated and conveyed to the sheet conveyance path 11k while separating the sheets P one by one. At this time, the brush roller 11h rotates while the sheet-like pushing member is rounded so as not to disturb the separation of the paper sheet P. Further, the pressing plate 11c and the bottom belt 11b are interlocked so that a predetermined pressure is applied to the pickup roller 12p. In this way, the separation / stacking mechanism can separate and reliably release the sheets P stacked in the stacking space 11s one by one during separation.

  By using the above-mentioned configuration, especially the separation / accumulation guide that is displaced in three places, the fall-prevention mechanism, and the lock link mechanism, the guide parts and drive means have been simplified, reduced in cost, and reduced in size. Is feasible. In addition, this invention is not limited to the said Example, A various deformation | transformation is possible within the range of the meaning of this invention.

  Modification 1: In the above embodiment, the fall prevention levers are arranged at three locations, but the number of fall prevention levers is not limited to this as long as the fall of the paper sheets can be prevented.

  Variation 2: In the above embodiment, the shape of the fall prevention lever is different between the center and the outside, but the shape of all fall prevention levers may be the same, and the shape of each fall prevention lever May have different shapes.

  Modification 3: The separation / stacking guide 11f has a divided shape as shown in a side view shown in FIG. 11A and an arrow view from the direction of arrow I shown in FIG. You may have a function of a fall prevention lever.

  Modification 4: In the above embodiment, the plurality of hook-shaped protrusions 13h of the top guide 11o are arranged side by side at the same position in the front-rear direction of the apparatus. By shifting the position of the protrusion 13h with respect to the front-rear direction of the apparatus, the timing at which each fall-down prevention lever protrudes may be made different.
