JP, 2009-230746, A

Some card readers have, for example, a fixed center distance between a rubber roller facing the card transport path from above and a rubber roller facing the card transport path from below. In the case of this card reader, unless the outer diameter of the rubber ring of the rubber roller is set to be slightly larger and the hardness of the rubber ring is set to be relatively low, slippage occurs between the rubber roller and the card so that the card can be properly conveyed. It may disappear.

On the other hand, if the hardness of the rubber ring of the rubber roller is lowered (that is, the rubber ring is softened), for example, when an unexpected external force acts on the rubber ring during the transportation of the card, the rubber ring may come off from the core member. is there. In order to prevent the rubber ring from coming off from the core member, the outer diameter of the collar portion formed on the core member may be increased. However, if the outer diameter of the collar portion is increased, the rubber ring will be cored when the rubber roller is assembled. It becomes difficult to fit the member.

Then, the subject of this invention is a card reader provided with a rubber roller which has a rubber ring and a core member as a conveyance roller for conveying a card in a card conveyance path, and a rubber ring is easily fitted to a core member at the time of assembly of a conveyance roller. Even if it is possible, it is an object of the present invention to provide a card reader capable of preventing a rubber ring having a relatively low hardness from coming off the core member in the assembled card reader.

In order to solve the above problems, the card reader of the present invention includes a main body frame in which a card transport path for transporting a card is formed, and a transport roller for transporting the card in the card transport path. A ring-shaped rubber ring that is formed in an annular shape and constitutes the outer peripheral portion of the conveying roller; and a core member that holds the rubber ring on the inner peripheral side of the rubber ring, and the core member includes one end surface of the rubber ring. And a second collar portion with which the other end surface of the rubber ring contacts, the outer diameter of the second collar portion is smaller than the outer diameter of the first collar portion, The main body frame is characterized in that a wall surface adjacent to the second flange portion is formed.

In the card reader of the present invention, the outer diameter of the second collar portion formed on the core member is smaller than the outer diameter of the first collar portion. Therefore, in the present invention, in the assembled card reader, even if the outer diameter of the first brim portion is large so that the rubber ring having a relatively low hardness does not come off from the core member to the first brim portion side, It is possible to easily fit the rubber ring to the core member from the second flange portion side during assembly. Further, in the present invention, since the wall surface adjacent to the second collar portion is formed on the main body frame, the rubber ring of the second collar portion can be easily fitted to the core member when the transport roller is assembled. Even if the outer diameter is small, the wall of the main body frame can prevent the rubber ring having a relatively low hardness from coming off from the core member toward the second flange portion in the assembled card reader. Therefore, in the present invention, even if the rubber ring can be easily fitted to the core member at the time of assembling the transport roller, the rubber ring having a relatively low hardness is prevented from coming off the core member in the card reader after assembly. It will be possible.

In the present invention, it is preferable that the first flange portion and the second flange portion are formed in the entire area of the transport roller in the circumferential direction. According to this structure, in the assembled card reader, the rubber ring does not easily come off from the core member.

In the present invention, the card reader includes, for example, a rotary shaft to which the carrying roller is attached and which rotates together with the carrying roller, and the main body frame is one side surface of the main body frame in the width direction of the card carried in the card carrying path. And a second side plate that constitutes the other side surface of the main body frame in the width direction of the card and that rotatably supports the other end side of the rotary shaft. And the transport rollers are attached to both ends of the rotary shaft, and the first flanges of the two transport rollers attached to both ends of the rotary shaft are arranged inside the rubber ring in the width direction of the card. The inner side surfaces of the first side plate and the second side plate in the width direction of the card are wall surfaces.

In this case, it is possible to prevent the rubber ring from coming off from the core member to the second flange portion side by using the first side plate and the second side plate forming the side surface of the body frame. Therefore, as compared with the case where a member for preventing the rubber ring from coming off from the core member to the second flange portion side is separately provided, the structure of the card reader is simplified and the rubber ring is removed from the core member. 2 It is possible to prevent it from coming off on the flange side.

In the present invention, the core member is made of resin, for example.

In the present invention, the core member includes a base portion on which an outer peripheral surface with which the inner peripheral surface of the rubber ring contacts is formed, and one of the first flange portion and the second flange portion is formed integrally with the base portion. It is preferable that the other one of the first brim portion and the second brim portion is formed separately from the base portion and fixed to the base portion. With this configuration, for example, it is possible to simplify the configuration of the mold for forming the core member, as compared with the case where the first flange portion and the second flange portion are integrally formed with the base portion. become.

In the present invention, the inner peripheral surface of the rubber ring is formed with a plurality of protrusions protruding inward in the radial direction of the rubber ring, and the core member is formed with a plurality of recesses for engaging the protrusions. It is preferable. According to this structure, it is possible to prevent slippage between the outer peripheral surface of the core member and the inner peripheral surface of the rubber ring.

As described above, according to the present invention, in the card reader including the rubber roller having the rubber ring and the core member as the transfer roller for transferring the card in the card transfer path, the rubber ring can be easily used as the core member when the transfer roller is assembled. Even if it can be fitted, it is possible to prevent the rubber ring having a relatively low hardness from coming off the core member in the assembled card reader.

(Structure of the transport roller and the peripheral portion of the transport roller)
FIG. 3 is a cross-sectional view for explaining the configuration of the transport rollers 24, 25 and the peripheral portions of the transport rollers 24, 25 shown in FIG. FIG. 4 is a cross-sectional view for explaining the configuration of the transport roller 24 shown in FIG.

The transport roller 24 is a rubber roller including a rubber ring 26 made of rubber that forms an outer peripheral portion of the transport roller 24, and a core member (core metal) 27 that holds the rubber ring 26. The rubber ring 26 is formed in an annular shape. Specifically, the rubber ring 26 is formed in a flat cylindrical shape. The hardness of the rubber ring 26 is relatively low. The rubber ring 26 contacts the lower surface of the card 2 with a predetermined contact pressure. The core member 27 is made of resin. The core member 27 is formed into a flat cylindrical shape with a collar having flange portions (flange) 27a and 27b at both ends. The core member 27 is composed of a cylindrical base portion 27c and two flange portions 27a and 27b. The rubber ring 26 is lightly press-fitted into the base portion 27c and fitted therein, and is arranged between the collar portion 27a and the collar portion 27b.

The inner peripheral surface of the rubber ring 26 is in contact with the outer peripheral surface of the base portion 27c. That is, the base portion 27c is formed with an outer peripheral surface with which the inner peripheral surface of the rubber ring 26 contacts. The core member 27 holds the rubber ring 26 on the inner peripheral side of the rubber ring 26. As shown in FIG. 4, a plurality of protrusions 26 a are formed on the inner peripheral surface of the rubber ring 26 so as to protrude inward in the radial direction of the rubber ring 26. The plurality of protrusions 26a are formed at a constant pitch in the circumferential direction of the rubber ring 26. A plurality of recesses 27d with which the protrusions 26a engage are formed on the outer peripheral surface of the base portion 27c.

The collar portion 27a extends in a flange shape from one end of the base portion 27c to the outside in the radial direction of the core member 27. The brim portion 27b extends from the other end of the base portion 27c to the outer side in the radial direction of the core member 27 in a brim shape. That is, the core member 27 is formed with the flange portions 27a and 27b connected to both ends of the base portion 27c. The collar portions 27a and 27b are formed in an annular shape. That is, the flange portions 27 a and 27 b are formed on the entire area of the conveying roller 24 in the circumferential direction (the entire area of the rubber ring 26 in the circumferential direction). One end surface of the rubber ring 26 is in contact with the collar portion 27a. The other end surface of the rubber ring 26 is in contact with the collar portion 27b. The collar portion 27a of the present embodiment is a first collar portion, and the collar portion 27b is a second collar portion.

The collar portion 27b is formed integrally with the base portion 27c. On the other hand, the collar portion 27a is formed separately from the base portion 27c and is fixed to the base portion 27c. The outer diameter of the collar portion 27b is smaller than the outer diameter of the collar portion 27a. The outer diameter of the flange portion 27b is set to a size that allows the rubber ring 26 to be easily fitted to the core member 27 from the flange portion 27b side when the transport roller 24 is assembled. The outer diameter of the collar portion 27a is set to a size such that the rubber ring 26 does not come off from the core member 27 in the assembled card reader 1. In this embodiment, the outer diameter of the collar portion 27b is smaller than the value obtained by dividing the sum of the inner diameter of the rubber ring 26 and the outer diameter by 2, and the outer diameter of the collar portion 27a is equal to the inner diameter of the rubber ring 26. It is slightly larger than the value obtained by dividing the sum with the outer diameter by 2.

The transport roller 25 is formed in the same shape as the transport roller 24. That is, like the transport roller 24, the transport roller 25 is a rubber roller including a rubber ring 26 that forms an outer peripheral portion of the transport roller 25 and a core member 27 that holds the rubber ring 26. Therefore, description of the specific configuration of the transport roller 25 is omitted.

The transport roller 24 is attached to the rotary shaft 30. The transport roller 25 is attached to the rotary shaft 31. The rotary shafts 30 and 31 are arranged so that the axial directions of the rotary shafts 30 and 31 and the left-right direction coincide with each other. The rotating shafts 30 and 31 are inserted into the inner peripheral side of the core member 27. Parallel pins (not shown) are attached to the rotary shafts 30 and 31. Both ends of the parallel pin project from the rotary shafts 30, 31 in the radial direction of the rotary shafts 30, 31. Further, both ends of the parallel pin are engaged with the core member 27.

Therefore, the transport roller 24 rotates together with the rotary shaft 30, and the transport roller 25 rotates together with the rotary shaft 31. A retaining ring 32 is attached to the rotary shafts 30 and 31. The stop ring 32 and the parallel pin regulate the movement of the transport roller 24 with respect to the rotation shaft 30 and the movement of the transport roller 25 with respect to the rotation shaft 31 in the left-right direction.

The right ends of the rotary shafts 30 and 31 are rotatably supported by the side plate 18. Specifically, the right ends of the rotary shafts 30 and 31 are rotatably supported by a bearing 33 attached to the side plate 18, and rotatably supported by the side plate 18 via the bearing 33. The left ends of the rotating shafts 30 and 31 are rotatably supported by the side plate 19. Specifically, the left ends of the rotary shafts 30 and 31 are rotatably supported by a bearing 33 attached to the side plate 19, and rotatably supported by the side plate 19 via the bearing 33. The distance between the rotating shaft 30 and the rotating shaft 31 is fixed. That is, the axial distance between the transport roller 24 and the transport roller 25 is fixed.

In this embodiment, the transport rollers 24 are attached to both ends of the single rotary shaft 30. Further, the transport rollers 25 are attached to both ends of the single rotary shaft 31, respectively. That is, two conveying rollers 24 are attached to one rotating shaft 30, and two conveying rollers 25 are attached to one rotating shaft 31. The conveyance roller 24 attached to the right end side of the rotating shaft 30 and the conveyance roller 25 attached to the right end side of the rotating shaft 31 are arranged on the right end side of the card conveying path 4 and are attached to the left end side of the rotating shaft 30. The transport roller 25 attached to the left end side of the rotating shaft 31 is arranged on the left end side of the card transport path 4.

The power of the motor 20 is transmitted to the rotary shafts 30 and 31 by a power transmission mechanism including a pulley, a belt, and a gear. That is, in this embodiment, the power of the motor 20 is transmitted to both the transport roller 24 and the transport roller 25. The transport roller 24 and the transport roller 25 are in contact with each other with a predetermined contact pressure. Specifically, the rubber ring 26 of the transport roller 24 and the rubber ring 26 of the transport roller 25 are in contact with each other at a predetermined contact pressure. The card 2 is conveyed while being sandwiched between the conveyance rollers 24 and 25. Specifically, the card 2 is conveyed in such a manner that both end portions of the card 2 in the left-right direction are sandwiched between the rubber ring 26 of the conveyance roller 24 and the rubber ring 26 of the conveyance roller 25.

The flange portions 27a of the two transport rollers 24 attached to both ends of the rotating shaft 30 are arranged inside the rubber ring 26 in the left-right direction. That is, the flange portion 27 a of the conveying roller 24 attached to the right end side of the rotating shaft 30 is arranged on the left side of the rubber ring 26, and the flange portion 27 a of the conveying roller 24 attached to the left end side of the rotating shaft 30 is the rubber ring 26. It is located on the right side of. Similarly, the flange portions 27a of the two transport rollers 25 attached to both ends of the rotary shaft 31 are arranged inside the rubber ring 26 in the left-right direction. That is, the flange portion 27 a of the conveying roller 25 attached to the right end side of the rotating shaft 31 is arranged on the left side of the rubber ring 26, and the flange portion 27 a of the conveying roller 25 attached to the left end side of the rotating shaft 31 is the rubber ring 26. It is located on the right side of.

The flange portion 27b of the conveying roller 24 attached to the right end side of the rotating shaft 30 and the flange portion 27b of the conveying roller 25 attached to the right end side of the rotating shaft 31 are provided on the left side surface so as to face the left side surface 18a of the side plate 18. It is arranged adjacent to 18a. The flange portion 27b of the conveying roller 24 attached to the left end side of the rotating shaft 30 and the flange portion 27b of the conveying roller 25 attached to the left end side of the rotating shaft 31 are arranged on the right side surface 19a of the side plate 19 so as to face the right side surface 19a. It is arranged adjacent to 19a.

That is, the left side surface 18a and the right side surface 19a, which are the inner side surfaces of the side plates 18 and 19 in the left-right direction, are adjacent to the flange portion 27b, and the body frame 5 includes the left side surface 18a and the right side surface adjacent to the flange portion 27b. 19a is formed. The distance in the left-right direction between the collar portion 27b arranged on the right end side of the card transport path 4 and the left side surface 18a, and the lateral distance between the collar portion 27b arranged on the left end side of the card transport path 4 and the right side surface 19a. The distance is smaller than the width of the rubber ring 26 (width in the left-right direction). The left side surface 18a and the right side surface 19a of this embodiment are wall surfaces adjacent to the flange portion 27b.

(Main effects of this embodiment)
As described above, in the present embodiment, the outer diameter of the brim portion 27b is smaller than the outer diameter of the brim portion 27a, and when the transport rollers 24 and 25 are assembled, the rubber member is attached to the core member 27 from the brim portion 27b side. The size is set so that the wheel 26 can be easily fitted. Therefore, in the present embodiment, even if the outer diameter of the flange portion 27a is set so that the rubber ring 26 does not come off from the core member 27 to the flange portion 27a side in the assembled card reader 1, the conveyance rollers 24 and 25 are assembled. At this time, it becomes possible to easily fit the rubber ring 26 to the core member 27 from the side of the flange portion 27b.

Further, in the present embodiment, the flange portion 27b is adjacent to the left side surface 18a of the side plate 18 or the right side surface 19a of the side plate 19, so that the rubber ring 26 can be easily fitted to the core member 27 when the transport rollers 24 and 25 are assembled. Even if the outer diameter of the flange portion 27b is reduced so that the rubber ring 26 can be prevented from coming off from the core member 27 to the flange portion 27b side in the assembled card reader 1 by the left side surface 18a or the right side surface 19a. It becomes possible to do. Therefore, in the present embodiment, even if the rubber ring 26 can be easily fitted to the core member 27 when the transport rollers 24 and 25 are assembled, the rubber ring 26 having a relatively low hardness is the core in the assembled card reader 1. It becomes possible to prevent the member 27 from coming off.

In addition, in the present embodiment, in the assembled card reader 1, the rubber ring 26 is detached from the core member 27 to the flange portion 27b side so that the left side surface 18a of the side plate 18 or the right side surface of the side plate 19 constituting the side surface of the main body frame 5 is separated. Since it can be prevented by using 19a, the card reader 1 is different from the case where a member for preventing the rubber ring 26 from coming off from the core member 27 toward the flange portion 27b is separately provided. It is possible to prevent the rubber ring 26 from coming off from the core member 27 to the flange portion 27b side while simplifying the configuration of.

In this embodiment, the flange portions 27a and 27b are formed in an annular shape and are formed in the entire area of the transport rollers 24 and 25 in the circumferential direction. Therefore, in this embodiment, in the assembled card reader 1, the rubber ring 26 is unlikely to come off from the core member 27. Further, in the present embodiment, since the plurality of protrusions 26a are formed on the inner peripheral surface of the rubber ring 26 and the plurality of recesses 27d with which the protrusions 26a engage are formed on the outer peripheral surface of the base portion 27c, the outer peripheral surface of the base portion 27c. It is possible to prevent slippage between the inner peripheral surface of the rubber ring 26 and the inner peripheral surface of the rubber ring 26.

In the present embodiment, the collar portion 27b is formed integrally with the base portion 27c, but the collar portion 27a is formed separately from the base portion 27c and is fixed to the base portion 27c. Therefore, in this embodiment, as compared with the case where both the collar portion 27a and the collar portion 27b are integrally formed with the base portion 27c, for example, the structure of the mold for forming the core member 27 can be simplified. Will be possible.
