The upper edge portion, that is, the edge portion on the feed roller 15 side contacts the support member 47 and moves the support member 47 away from the feed roller 15. Thus, the upper edge of the notch of the hook-shaped part 49a provided on the gate hook 49, that is, the edge on the feed roller 15 side becomes the first contact part 49b. On the other hand, when the gate hook 49 is moved in the direction from the support member 47 side toward the feed roller 15 side by driving the second motor 65, the lower edge portion of the notch of the hook-shaped portion 49a provided on the gate hook 49, that is, the gate roller The edge portion on the 43 side contacts the support member 47 and moves the support member 47 in the direction toward the feed roller 15. Thus, the lower edge portion of the notch of the hook-shaped portion 49a provided on the gate hook 49, that is, the edge portion on the gate roller 43 side becomes the second contact portion 49c.

  Further, a spring 67 that is an elastic member is attached between the end of the gate hook 49 opposite to the side on which the hook-shaped portion 49 a is provided and the second guide plate 47 b of the support member 47. The spring 67 urges the support member 47 in the end portion direction opposite to the side where the hook-shaped portion 49a of the gate hook 49 is provided, that is, in the direction toward the feed roller 15 or the pinch roller 17. The gate roller 43 and the push roller 45 supported by the support member 47 are biased in the direction toward the feed roller 15 and the pinch roller 17.

The support member 47 is in a state where the first contact portion 49b of the hook-shaped portion 49a provided on the gate hook 49 is in contact with the support member 47 and moved in a direction away from the feed roller 15. When a force larger than the biasing force of the spring 67 is applied, the spring 67 can move within the range h shown in FIG. On the other hand, to move the second contact with the support member 47 to the contact portion 49 c supporting member 47 of the hook-shaped portion 49a formed in the gate hook 49 toward the feed roller 15, the support member 47 the feed roller 15 4, the second contact portion 49 c of the hook-shaped portion 49 a provided on the gate hook 49 is defined by a stopper 47 c provided on the support member 47, and the gate roller 43 shown in FIG. The movement of the support member 47 in the direction away from the feed roller 15 is restricted so as to maintain the overlap distance M between the feed roller 15 and the feed roller 15.

Accordingly, the sheet-like medium is introduced into the storage chamber 3 through the opening 37 and is transported from the storage chamber 3 toward the transport path 5 or is transported from the transport path 5 toward the storage chamber 3. Are stacked and taken out from the opening 37.

  When the sheet-like medium is introduced into the storage chamber 3 from the opening 37 and is transported from the storage chamber 3 toward the transport path 5, the plurality of stacked sheet-like media are picked up from the pickup roller 13 side. The high-friction body 13a is intermittently fed into the conveyance path 5 by contact with the portion where the high-friction body 13a is attached. Here, when the sheet-like medium sent from the storage chamber 3 to the conveyance path 5 is a thin and flexible sheet-like medium such as banknotes, the gate hook 49 is driven by the second motor 65 to the support member 47 side. The second abutting portion 49c of the gate hook 49 abuts on the support member 47 and moves the support member 47 toward the feed roller 15 side. Then, the support member 47 is closest to the first guide plate 29, and the feed roller 15 and the gate roller 43 are most overlapped.

  The second motor 65 supports, for example, information obtained by detecting the thickness of the sheet-like medium in the accommodation chamber 3 or the conveyance path 5 with a sensor, or a fixed terminal device handling the sheet-like medium into the accommodation chamber 3. The distance between the feed roller 15 and the gate roller 43 is appropriately adjusted by controlling the driving according to information on the type of the sheet-like medium.

  In the state where the feed roller 15 and the gate roller 43 overlap most, the feed roller 15 and the gate roller 43 are not in contact with each other as shown in FIG. Thus, the large diameter portions of the feed roller 15 and the gate roller 43 are overlapped by a distance M in a direction orthogonal to the surface of the sheet medium 65. Thereby, the thin flexible sheet-like medium 65 such as banknotes is deformed into a waveform.

Such deformation increases the contact force between the feed roller 15 and the gate roller 43 and the sheet medium 65. At this time, the gate roller 43 does not rotate in the direction toward the conveyance path 5 due to the action of the one-way clutch 53, so that the sheet medium 65 overlaps between the feed roller 15 and the gate roller 43. Even if nipped, the sheet-like medium 65 in contact with the gate roller 43 is not held and conveyed by the gate roller 43, but only the sheet-like medium 65 in contact with the feed roller 15 is reliably separated and conveyed one by one.
Here, the size of the distance M at which the large diameter portions of the feed roller 15 and the gate roller 43 overlap each other affects the separation performance of the overlapped sheet-like medium, and therefore must be managed with a tolerance of, for example, several tens of μm. . On the other hand, in this embodiment, since the distance between the feed roller 15 and the gate roller 43 can be adjusted by the movement of the gate roller 43 supported by the support member 47, the second contact of the gate hook 49 is achieved. For example, a tolerance of several tens of μm is required only by a configuration in which the contact portion 49b moves the support member 47 in the direction of the feed roller 15 and the second contact portion 49b of the gate hook 49 restricts the movement of the support member 47 to determine the position. It is difficult to satisfy.

  For this reason, in the present embodiment, the support member 47 is provided with a stopper 47c, and the stopper 47c is brought into contact with a portion where the position relative to the feed roller 15 such as the first guide member 29 does not change to feed the feed roller 15 and the gate roller 43. The distance M where each large-diameter portion overlaps is determined, and further, the stopper 47c of the support member 47 is in contact with a portion where the position relative to the feed roller 15 such as the first guide member 29 does not change. The contact portion 49 b restrains the movement of the support member 47. By adopting such a configuration, the distance M can be defined by the stopper 47c provided on the support member 47, which is relatively easy to obtain processing accuracy, so that a tolerance of, for example, several tens of μm can be satisfied.

  On the other hand, when the sheet-like medium sent from the storage chamber 3 to the conveyance path 5 is a thick and relatively rigid sheet-like medium such as a plastic card, that is, as shown in FIG. The second motor 65 is driven to move from the feed roller 15 side toward the support member 47 side, and the first contact portion 49b of the gate hook 49 comes into contact with the support member 47 to move the support member 47 from the feed roller 15. Move away. The feed roller 15 and the gate roller 43 are arranged so that the distance between the outer peripheral surfaces of the feed roller 15 and the gate roller 43 is smaller than the thickness of the sheet-like medium according to the thickness of the sheet-like medium. The

  In this state, as shown in FIG. 5, when a thick and relatively rigid sheet-like medium 67 such as a plastic card enters between the feed roller 15 and the gate roller 43, the support member 47 Since it can move away from the feed roller 15 until it contacts the second contact portion 49c of the gate hook 49, the distance between the outer peripheral surfaces of the feed roller 15 and the gate roller 43 is the same distance as the thickness of the sheet-like medium. Spread to N. At this time, the support member 47 is urged toward the feed roller 15 by the urging force of the spring 67 attached between the gate hook 49 and the support member 47, so that the gate roller 43 is moved toward the feed roller 15 side. Accordingly, the sheet-like medium 67 can be held between the outer peripheral surfaces of the feed roller 15 and the gate roller 43.

  As described above, since the gate roller 43 does not rotate in the direction in which the medium is separated, even if the sheet-like medium 67 overlaps, the gate roller 43 can be separated and sent to the conveyance path 5 one by one.

  By the way, as shown in FIGS. 4 and 5, when a sheet-like medium is sandwiched between the feed roller 15 and the gate roller 43 having an outer peripheral surface that meshes in a concavo-convex shape, for example, a relatively strong sheet shape such as a banknote. Separation and conveyance can be performed without any problem with a medium or plastic sheet-like medium having a relatively high rigidity. However, a relatively weak sheet-like medium such as a transfer sheet, for example, may be creased or damaged when it is sandwiched between the feed roller 15 and the gate roller 43 that have an outer peripheral surface that engages in an uneven shape. There is sex. For this reason, in the case of a relatively weak sheet-like medium such as a transfer sheet, the sheet-like medium may not be sandwiched between the feed roller 15 and the gate roller 43 that have an outer peripheral surface that meshes in a concavo-convex shape.

  In the sheet-like medium handling apparatus 1 that can handle such a sheet-like medium, as shown in FIGS. 6 and 7, the gate serving as the second clamping member is separate from the gate roller 43 serving as the first clamping member. A pad 69 is provided, and the gate roller 43 and the gate pad 69 are switched according to the type of sheet medium. The gate pad 69 is a plate cam-shaped member attached to the shaft 51 of the gate roller 43, that is, a member protruding in one direction from the shaft 51, and a distal end portion having a flat end surface of the protruding portion Is attached with a high-friction body 69a such as rubber, and the end surface of the high-friction body 69a at the front end portion generates friction with the sheet-like medium. The shaft 51 is rotatably attached to the shaft 51 via a bearing 71. The shaft 51 can be rotated about the rotation axis regardless of the rotation of the shaft 51, and the gate pad 69 does not move even if the shaft 51 rotates.

  Such a gate pad 69 is provided at a position corresponding to the large diameter portion of the feed roller 15. In this embodiment, since one feed roller 15 has three large-diameter portions with two small-diameter portions sandwiched therebetween, the gate pad 69 also has one feed roller 15 with respect to the feed roller 15. Three are provided at positions corresponding to the large diameter portion. At this time, one gate pad 69 comes to the position of the small diameter portion corresponding to the large diameter portion of the feed roller 15 of the gate roller 43. For this reason, in the case of the configuration in which the gate pad 69 is provided, the gate roller 43 is provided in a state where only the large-diameter portion is made independent of the small-diameter portion as shown in FIG.

  The gate pad 69 is connected to a shaft of a solenoid-type actuator 73 attached to the side wall 47a of the support member 47, and the shaft 73a of the actuator 73 moves straight in the direction of arrow F shown in FIG. The shaft 51 between the state in which the body 69a side protrudes in the direction of the feed roller 15 from the outer peripheral surface of the gate roller 43 and the state in which the high friction body 69a side is accommodated inside the second guide plate 47b of the support member 47. Is rotated in the direction of arrow G shown in FIG. As a result, the gate pad 69 causes the high friction body 69a at the front end of the gate pad 69 to be more transported than the second guide plate 47b of the support member only when the sheet-like medium is sent from the storage chamber 3 to the transport path 5. That is, it can be made to protrude to the feed roller 15 side from the outer peripheral surface of the gate roller 43.

  With the configuration including such a gate pad 69, as shown in FIG. 7, a storage chamber for a sheet-like medium 75 which is not flexible like a banknote and is not hard like a plastic card or sheet. When the sheet-like medium 75 is conveyed from 3 to the conveyance path 5 and separated, the gate pad 69 is rotated to protrude from the second guide plate 47b of the support member 47 to the feed roller 15 side. Thus, the sheet-like medium 75 is sandwiched between the large-diameter portion of the feed roller 15 and the tip of the gate pad 69 to prevent the sheet-like medium 75 from being bent, and the sheet-like medium 75 is creased or damaged. Can be prevented.

  At this time, the high friction body 69a at the tip of the gate pad 69 prevents the movement of the sheet-like medium 75 in contact with the high-friction body 69a, so that the sheet-like medium 75 can be prevented from being conveyed in an overlapping manner. Note that when the sheet-like medium 75 is accumulated in the accommodation chamber 3, the gate pad 69 is accommodated inside the second guide plate 47 b of the support member 47 so as not to contact the sheet-like medium 75. The installation of the gate pad 69 is appropriately selected according to the type of sheet-like member that may be handled.

  On the other hand, when the sheet-shaped medium is accumulated in the storage chamber 3, the gate roller 43 rotates in accordance with the conveyed sheet-shaped medium and smoothly transports the sheet-shaped medium toward the storage chamber 3. However, as shown in FIG. 8, in the case of the sheet medium 77 that is relatively hard and hard to bend, the rear end portion of the sheet medium 77 on the conveyance path 5 side is the accommodation chamber of the second guide plate 47 b of the support member 47. There is a case where the sheet-like medium 77 is not flatly collected on the push plate 39 in the storage chamber 3 due to being caught by the end portion on the side 3 or the end edge portion of the portion rising toward the first guide plate 29 of the tray 35. is there.

  In the sheet medium handling apparatus 1 that may handle such a sheet medium 77, a sheet roller 79 is provided on the shaft 51 of the gate roller 43 side by side with the gate roller 43 as shown in FIG. 8. Therefore, the sheet roller 79 rotates together with the rotation of the shaft 51, that is, in conjunction with the rotation of the gate roller 43. The sheet roller 79 is provided with a sheet portion 79 a formed of a flat plate-like plastic or the like extending radially with respect to the shaft 51. The sheet portion 79a of the sheet roller 79 is provided with a length longer than the radius of the gate roller 43 and protruding from the gate roller 43, and further on the second guide plate 47b of the support member 47 and the first guide plate 29 of the tray 35. It is provided in a state of protruding from the portion rising toward the front.

  It should be noted that the sheet portion 79a of the sheet roller 79 is configured so that when the sheet-shaped medium is conveyed from the storage chamber 3 toward the conveyance path 5, the sheet roller 79 supports the first member 47 of the sheet roller 79 so as not to obstruct the conveyance of the sheet-shaped medium. It is partially provided only in the range of the angle that fits between the two guide plates 47b and the portion of the tray 35 that rises toward the first guide plate 29. Further, the surface of the sheet portion 79 a of the sheet roller 79 faces the conveyance direction of the sheet medium 77 in the conveyance path 5. The installation of the sheet roller 79 is appropriately selected according to the type of sheet-like member that may be handled.

  With such a configuration including the sheet roller 79, the sheet-like medium 77 can be reliably accumulated in the storage chamber 3. In this configuration, it is preferable that the shaft 51 is rotationally driven by a motor or the like, and a sensor or the like for detecting the position of the seat portion 79a is provided. Thereby, when the sheet portion 79a of the sheet roller 79 conveys the sheet-like medium from the storage chamber 3 toward the conveyance path 5, the sheet portion 79a of the sheet roller 79 does not protrude into the conveyance path 5. By rotating the sheet roller 79, all the sheet portions 79 a can be surely placed between the second guide plate 47 b of the support member 47 and the portion rising toward the first guide plate 29 of the tray 35.

  In the sheet-like medium conveyance device 1 according to the present embodiment, a feed roller 15 and a gate roller that separate a plurality of stacked sheet-like media one by one and send them to the conveyance path 5 according to the type of sheet-like medium to be handled. 43 from the position where the large diameter portion of the feed roller 15 and the large diameter portion of the gate roller 43 overlap, between the outer peripheral surface of the large diameter portion of the feed roller 15 and the outer peripheral surface of the large diameter portion of the gate roller 43. Can be adjusted up to a position separated by a predetermined interval. Accordingly, different types of sheet-like media can be handled by a single sheet-like medium handling device.

  Further, in the present embodiment, the adjusting means contacts the support member 47 that supports the gate roller 43, and moves the gate roller 43 in a direction away from the feed roller 15. A gate hook 49, which is a moving means provided with a second contact portion 49c that contacts and moves the gate roller 43 in the direction toward the feed roller 15, a second motor 65 for moving the gate hook 49, and not shown. By configuring the transmission mechanism and the support member 47 with a spring 67 that urges the feed roller 15 in the direction, the configuration of the adjusting means is simplified.

  In addition, when the gate roller 43 and the feed roller 15 come closest to the support member 47 of this embodiment, the gate roller 43 contacts the first guide plate 29 whose position does not change with respect to the feed roller 15. A stopper 47c is provided as a defining member that defines the overlap distance M when the feed roller 15 and the feed roller 15 are closest to each other and the portions facing each other overlap. Therefore, when the gate roller 43 and the feed roller 15 are closest, the accuracy of the tolerance of the overlapping distance M between the gate roller 43 and the feed roller 15 can be improved, and the sheet-like medium separation performance can be improved.

  The portion where the stopper 47c abuts may be anywhere as long as the position does not change with respect to the feed roller 15. However, the position does not change with respect to the feed roller 15 reliably regardless of the device configuration. Therefore, it is desirable that the first guide plate 29 and the shaft 19 of the feed roller 15 be a portion where the stopper 47c abuts. When it is not necessary to improve the tolerance of the distance M depending on the type of sheet-like medium to be handled, the second contact portion 49c of the gate hook 49 is not provided with a defining member such as the stopper 47c. It is also possible to adopt a configuration in which the distance M is adjusted only by restricting the movement of 47.

Further, in the present embodiment, the gate roller 43 supported by the support member 47 so as to be rotatable only in the direction from the conveyance path 5 toward the storage chamber 3 is used as a clamping member that clamps the sheet-like medium together with the feed roller 15. . For this reason, the sheet-like medium conveyance device 1 of the present embodiment separates the sheet-like medium accommodated in the accommodation chamber 3 one by one and sends it to the conveyance path 5, and from the conveyance path 5 toward the accommodation chamber 3. The conveyed sheet-like medium can be accumulated in the storage chamber 3, and the sheet-like medium can be delivered. However, in the sheet-like medium conveyance device used only for the role of separating the sheet-like medium accommodated in the accommodation chamber 3 one by one and sending it to the conveyance path 5, the holding member needs to be a roller such as the gate roller 43. Alternatively, it is possible to use members having various shapes in which the portion facing the feed roller 15 is formed in a concavo-convex shape that meshes with the concavo-convex shape of the outer periphery of the feed roller 15.

  Further, in the present embodiment, the conveyance path 5 includes the linear first guide surface of the first guide plate 29 provided on the feed roller 15 side and the second guide plate 47 b provided on the support member 47. By being formed with a linear second guide surface facing in parallel with one guide surface, it is possible to handle a sheet-like medium that is difficult to bend. At this time, the pinch roller 17 provided on the feed roller 15 side and the push roller 45 that sandwiches the sheet-like medium between the pinch roller 17 are provided. The push roller 45 is a support member together with the gate roller 43. 47 is rotatably supported. Therefore, since the push roller 45 moves simultaneously with the gate roller 43, the interval between the pinch roller 17 and the push roller 45 can be adjusted simultaneously by adjusting the interval between the feed roller 15 and the gate roller 43.

  However, when a sheet-like medium that is difficult to bend is not handled, the conveyance path does not need to be linear, and in this case, a configuration in which the pinch roller 17 and the push roller 45 are not provided may be employed.

  In addition, the present invention is not limited to the configuration of the present embodiment, and a sheet-like medium is provided between the roller for conveying the sheet-like medium fed from the storage chamber in the conveyance path such as the feed roller 15 and the roller. The present invention can be applied to various sheet-like medium handling apparatuses provided with a clamping member such as a guide roller 43 for separating the sheet-like members that are overlapped by sandwiching the members one by one.
