The medium feeding device 1 shown in FIG. 1 includes a medium storage unit 10, a feeding roller 20, a sponge rubber 30 that is an example of a first elastic body, and a rubber 40 that is an example of a second elastic body. .

  The medium feeding device 1 includes a guide plate 50, an urging mechanism 60, a medium upper urging mechanism 70, a center panel 80, a movable portion 91, and a fixed portion 92.

  The medium feeding device 1 is arranged, for example, in a passbook printer in an automatic teller machine (ATM) and feeds the medium 100. The medium 100 is a passbook when the medium feeding device 1 is arranged in a passbook printer, but may be another medium such as a deposit / withdrawal form (form).

  As illustrated in FIG. 1, the medium storage unit 10 stores the medium 100 in each of a first storage unit 10 a and a second storage unit 10 b that are arranged to face each other with the feeding roller 20 interposed therebetween, for example. The medium 100 is inserted into the medium storage unit 10 from above, for example, by a human hand. Note that the medium storage unit 10 may store the medium 100 in a single storage unit instead of the two storage units of the first storage unit 10a and the second storage unit 10b.

  As shown in FIGS. 3 to 5, the medium accommodating portion 10 includes a first outer wall 11 and a second outer wall 12 that have a quadrangular shape (a U-shape or a U-shape) with one side opened in a plan view. . The first outer wall 11 and the second outer wall 12 are fixed so that one side of the opening faces each other. For example, the first outer wall 11 and the second outer wall 12 can be made common by using the same part having the same shape. The material of the 1st outer wall 11 and the 2nd outer wall 12 is a plastics, for example, and weight reduction is achieved rather than the metal material.

  The feeding roller 20 feeds out one medium 100 (P) at the feeding position from the medium storage unit 10. The feeding rollers 20 are arranged in two numbers (see FIGS. 3 and 4) for feeding out the medium 100 accommodated in the first accommodating portion 10a, and for delivering the medium 100 accommodated in the second accommodating portion 10b. There are four in total. As shown in FIGS. 3 and 4, the two feeding rollers 20 are connected by a roller rotation shaft 93. The feeding roller 20 is provided so as to penetrate the center panel 80.

  It should be noted that the two feeding rollers 20 disposed in the first housing portion 10a are 2 of the second housing portion 10b in order to avoid interference with the two feeding rollers 20 disposed in the second housing portion 10b. It is provided above the two feeding rollers 20. It should be noted that the number of the feeding rollers 20 may be one or three or more instead of being arranged in order to feed out one medium 100.

  Two sponge rubbers 30 shown in FIGS. 2A and 2B are provided in each of the accommodating portions 10a and 10b (only the first accommodating portion 10a is shown in FIGS. 3 to 5), for example, as indicated by broken lines in FIGS. Placed one by one. The sponge rubber 30 forms a first gate G1 that separates the medium 100 (P) fed by the feeding roller 20 from the plurality of media 10 accommodated in the medium accommodating unit 10 by being deformed by elastic force. However, the first gate G1 of the sponge rubber 30 separates the medium 100 to such an extent that not only the medium 100 at the feeding position P but also a plurality of media 100 can be passed simultaneously. This is to ensure that the fed medium 100 (P1) can pass through the first gate G1 of the sponge rubber 30 with certainty.

  The sponge rubber 30 is provided on the bottom surface of the guide plate 50 and is provided so as to protrude from the bottom surface of the guide plate 50 to the center panel 80 side.

  As shown in FIGS. 2A and 2B, the guide plate 50 includes a horizontal surface 50 a and an inclined surface 50 b inclined downward from the horizontal surface 50 a toward the center panel 80. The guide plate 50 is in contact with the bottom surfaces of the plurality of media 100 accommodated in the medium accommodating unit 10, and guides the plurality of media 100 toward the first gate G1 on the inclined surface 50b. The sponge rubber 30 is provided on the bottom surface of the guide plate 50 so as to be positioned below both the horizontal surface 50a and the inclined surface 50b.

  As shown in FIGS. 3 to 5, two guide plates 50 are arranged in each of the housing portions 10 a and 10 b (only the first housing portion 10 a is shown in FIGS. 3 to 5). These two guide plates 50 are provided integrally with each other, for example, and are connected to each other below the guide plate 50.

  As shown in FIGS. 2A and 2B, the rubber 40 separates the medium 100 fed by the feeding roller 20 from the plurality of media 100 that have passed through the first gate G1 by being deformed by an elastic force. In the rubber 40, a V-groove 40a, which is an example of a cut, is formed so as to open to the center panel 80 side.

  The rubber 40 forms the second gate G2 in the upper portion 40b above the V groove 40a. The second gate G2 of the upper portion 40b separates the medium 100 fed by the feeding roller 20 from the plurality of media 100 that have passed through the first gate G1 by being deformed by an elastic force. However, similarly to the first gate G1, the second gate G2 of the upper portion 40b can pass not only the medium 100 at the feeding position P but also a plurality of media 100 at the same time. The upper portion 40b may be inclined so as to guide the medium 100 into the V groove 40a.

  Further, the rubber 40 forms a third gate G3 in the lower portion 40c below the V groove 40a. The third gate G3 of the lower portion 40c separates the medium 100 fed by the feeding roller 20 from the plurality of media 100 that has passed through the second gate G2 by being deformed by elastic force.

  As shown in FIGS. 3 to 5, two rubbers 40 are provided between the two sponge rubbers 30 in plan view in each of the housing parts 10 a and 10 b (only the first housing part 10 a is shown in FIGS. 3 to 5). Has been placed.

  As shown in FIGS. 2A and 2B, the rubber 40 is provided on the surface of the movable portion 91 on the center panel 80 side.

  Two movable portions 91 are provided in the same manner as the rubber 40 and are urged toward the center panel 80 by a compression spring (not shown) provided between the movable portions 91 and the fixed portion 92. Thereby, the rubber 40 is also urged toward the center panel 80 side. For example, the fixing portion 92 is fixed to the guide plate 50. The two movable parts 91 may be one integral movable part 91, and the number of the fixed parts 92 may be one or plural.

  The hardness (H1) of the first elastic body taking the sponge rubber 30 as an example is desirably lower than the hardness (H2) of the second elastic body taking the rubber 40 as an example (H1 <H2). This is to more reliably separate the medium 100 (P) at the feeding position in the rubber 40 (second elastic body). For example, the first elastic body and the second elastic body have the same hardness. The material (H1 = H2) or the same material can be used, and the hardness of the first elastic body can be made higher than the hardness of the second elastic body (H1> H2).

  Note that although the sponge rubber 30 is provided on the guide plate 50 and the rubber 40 is provided on the movable portion 91, the arrangement positions of the sponge rubber 30 and the rubber 40 are not particularly limited.

  The urging mechanism 60 shown in FIGS. 3 and 6 urges the plurality of media 100 accommodated in the medium accommodating portion 10 to the feeding position P side (the feeding roller 20 side or the center panel 80 side) by the feeding roller 20. . As shown in FIG. 3, the urging mechanism 60 is disposed in each of the accommodating portions 10a and 10b (only the first accommodating portion 10a is shown in FIG. 3).

  The urging mechanism 60 includes a contact portion 61, a base portion 62, a compression spring 63, a connecting portion 64, and a tension spring 65. Instead of the base portion 62, the first outer wall 11 and the second outer wall 12 of the medium accommodating portion 10 can be used.

  The abutting portion 61 abuts on the medium 100. As shown in FIG. 7A, the abutting portion 61 has a feeding position P side (feeding side) on the bottom surface side of the medium 100 with respect to the surface (virtual plane) S orthogonal to the compression direction D of the compression spring 63. It has a contact plate 61a that contacts the medium 100 with a surface inclined so as to be closer to the roller 20 side or the center panel 80 side.

  Two compression springs 63 are provided between the base portion 62 and the contact portion 61 facing the contact portion 61 to press the contact portion 61, and as a result, the medium 100 is moved to the feeding position P side as described above. Energize.

  The connection part 64 includes a first connection bar 64 a and a second connection bar 64 b provided so as to intersect with each other, and connects the contact part 61 and the base part 62.

  The first connecting bar 64a is fixed to the contact portion 61 at one end. The other end of the first connecting bar 64 a is fixed to the base 62 so as to be movable along the base 62.

  The second connecting bar 64b is fixed to the base portion 62 at one end. The other end of the second connection bar 64 b is fixed to the contact portion 61 so as to be movable along the contact portion 61.

  Accordingly, the angle formed by the first connection bar 64a and the second connection bar 64b changes according to the expansion / contraction state of the compression spring 63.

  The tension spring 65 is disposed, for example, between the first connecting bar 64 a and the base portion 62 in the connecting portion 64. The tension spring 65 is pulled and the tensile strength is increased as the compression spring 63 is compressed and the fixing position of the first connecting bar 64a is further away from the fixing position of the base portion 62. As a result, the tension spring 65 is pulled as the compression spring 63 is compressed, and exerts a force against the urging force of the compression spring 63. Therefore, when the number of the media 100 stored in the medium storage unit 10 is large, the urging force that increases and strengthens the compression amount of the compression spring 63 is increased, and when the number of the media 100 is small (when the compression amount of the compression spring 63 is small). The urging force of the compression spring 63 can be brought close to.

  As shown in FIGS. 7A and 7B, the medium upper portion biasing mechanism 70 includes a medium upper portion contact plate 71 and a medium upper contact plate compression spring 72. The medium upper abutment plate compression spring 72 presses the medium upper abutment plate 71 so that the upper portions of the plurality of media 100 accommodated in the medium accommodating portion 10 are pushed in the pressing direction of the compression spring 63 (by the feeding roller 20). It is biased to the opposite side (ie, the compression direction D of the compression spring 63 shown in FIG. 7A) to the feed position P side. The contact surface 71a of the medium upper contact plate 71 is preferably parallel to the contact plate 61a.

  As shown in FIG. 1, the medium 100 fed out of the medium feeding device 1 by the feeding roller 20 is transferred to another medium such as a passbook printer in an automatic teller machine (ATM) by a conveying roller 110 and a conveying belt 120. It is transported towards the device.

  In the embodiment described above, the sponge rubber 30 (an example of the first elastic body) deforms the medium 100 fed out by the feeding roller 20 from the plurality of media 100 accommodated in the medium accommodating unit 10 by elastic force. Thus, the first gate G1 to be separated is formed. Further, the rubber 40 (an example of a second elastic body) is a second material that separates the medium 100 fed by the feeding roller 20 from the plurality of media 100 that has passed through the first gate G1 by being deformed by elastic force. A gate G2 is formed.

  Therefore, the medium 100 fed out by the feeding roller 20 can be separated with a simple configuration. Therefore, according to the present embodiment, the structure of the medium feeding device 1 can be simplified. As an additional effect, the material of the medium accommodating portion 10 is not a stainless material but a plastic material, and the first outer wall 11 and the second outer wall 12 that are the same shape and the same part of the medium accommodating portion 10 are used. 1 and the acceleration roller 230 and the separation mechanism 240 are omitted. As a whole, the medium feeding device 1 in FIG. 1 is 8.6% higher than the medium feeding device 201 in FIG. It can be reduced, the number of parts can be reduced by 35%, and the weight can be reduced by 28%.

  Further, in the present embodiment, the rubber 40 (an example of the second elastic body) is formed with a V-groove 40a (an example of a cut), and the rubber 40 has the second gate G2 disposed more than the V-groove 40a. The upper upper portion 40b is formed. Further, the rubber 40 deforms the medium 100 fed by the feeding roller 20 from the plurality of media 100 that has passed through the second gate G2 in the lower portion 40c below the V-groove 40a by elastic force. A third gate G3 to be separated is formed. Therefore, the medium 100 fed out by the feeding roller 20 can be more reliably separated with a simple configuration.

  Further, in the present embodiment, the guide plate 50 is in contact with the bottom surfaces of the plurality of media 100 accommodated in the medium accommodating unit 10, and includes the inclined surfaces 50b, for example, so that the plurality of media 100 are used as the first gate G1. Guide towards. The sponge rubber 30 (an example of a first elastic body) is provided so as to protrude from the bottom surface of the guide plate 50. Therefore, the structure of the medium feeding device 1 can be further simplified, and the medium 100 fed by the feeding roller 20 can be more reliably separated.

  In the present embodiment, the hardness (H1) of the first elastic body taking the sponge rubber 30 as an example is lower than the hardness (H2) of the second elastic body taking the rubber 40 as an example (H1 <H2). ). Therefore, the medium 100 fed out by the feeding roller 20 can be more reliably separated by separating in stages.

  In the present embodiment, the urging mechanism 60 urges the plurality of media 100 stored in the medium storage unit 10 toward the feeding position P by the feeding roller 20. The urging mechanism 60 is a compression spring that is provided between the abutting portion 61 that abuts against the medium 100 and the base portion 62 and the abutting portion 61 that face the abutting portion 61 and presses the abutting portion 61. 63, a connecting part 64 that connects the contact part 61 and the base part 62, and a biasing force of the compression spring 63 that is arranged between the base part 62 and the connecting part 64 and is pulled as the compression spring 63 is compressed. And a tension spring 65 that exerts a force against the above. For this reason, when the number of the media 100 accommodated in the medium accommodating portion 10 is large, even if the compression amount of the compression spring 63 increases, the urging force by the compression spring 63 is weakened, and when the number of the media 100 is small (the compression spring 63 It is possible to approach the urging force by the compression spring 63 when the compression amount is small.

  Further, in the present embodiment, the contact portion 61 of the urging mechanism 60 has the feeding position P on the bottom surface side of the medium 100 with respect to the surface S perpendicular to the compression direction D of the compression spring 63 rather than the top surface side of the medium 100. A contact plate 61a that comes into contact with the medium 100 with a surface inclined so as to be closer to the side. Therefore, the medium 100 can be tilted and reliably guided to the first gate G1, and the medium 100 fed by the feed roller 20 can be more reliably separated.

  Further, in the present embodiment, the medium upper portion biasing mechanism 70 is configured so that the upper portions of the plurality of media 100 accommodated in the medium accommodating portion 10 are defined as the feeding position P side (the pressing direction of the compression spring 63) by the feeding roller 20. Energize to the other side. Therefore, the medium 100 can be tilted and reliably guided to the first gate G1, and the medium 100 fed by the feed roller 20 can be more reliably separated.
