Description

The present invention relates to a card reader provided with a transport roller for transporting cards in a card transport path.

Conventionally, a card reader that reads magnetic data recorded on a card and records magnetic data on a card is known (see, for example, Patent Document 1). The card reader described in Patent Document 1 includes, for example, a transport roller 101 shown in FIG. 6 as a transport roller for transporting a card inside the card reader. The transfer roller 101 is composed of an annular rubber ring 102 that constitutes the outer peripheral surface of the transfer roller 101 and a core member 103 that holds the rubber ring 102 on the inner peripheral side of the rubber ring 102. The inner peripheral surface of the rubber ring 102 is adhered and fixed to the outer peripheral surface. The core member 103 is fixed to the rotating shaft.

Japanese Unexamined Patent Publication No. 8-315080

In the transport roller 101 shown in FIG. 6, since the inner peripheral surface of the rubber ring 102 is adhered and fixed to the outer peripheral surface of the core member 103, the adhesive force between the rubber ring 102 and the core member 103 varies. Then, the inner peripheral surface of the rubber ring 102 may be peeled off from the outer peripheral surface of the core member 103, and the rubber ring 102 may come off from the core member 103 in the axial direction of the rotation axis. Further, if the rubber ring 102 is removed from the core member 103, the card cannot be conveyed inside the card reader, and various problems such as clogging of the card may occur.

In order to prevent the rubber ring 102 from coming off from the core member 103 in the axial direction of the rotating shaft, an annular flange portion that contacts the end surface of the rubber ring 102 may be formed on the core member 103. However, if the core member 103 has an annular flange portion that contacts the end surface of the rubber ring 102, it becomes difficult to fit the rubber ring 102 into the core member 103 when assembling the transport roller 101.

Therefore, an object of the present invention is that in a card reader provided with a rubber roller having a rubber ring and a core member as a transport roller for transporting a card in a card transport path, the rubber ring is easily fitted to the core member when the transport roller is assembled. Even if it is possible, it is an object of the present invention to provide a card reader capable of preventing the rubber ring from coming off from the core member in the assembled card reader.

In order to solve the above problems, the card reader of the present invention is a card reader provided with a transport roller for transporting cards in a card transport path, and is a rubber ring formed in an annular shape and an inner circumference of the rubber ring. A transport roller having a core member for holding the rubber ring on the side, a rotating shaft to which the core member is fixed, and a retaining member for preventing the rubber ring from coming off from the core member in the axial direction of the rotating shaft. The retaining member is formed separately from the transport roller and the rotating shaft, and is attached to the core member or the rotating shaft from the outside in the radial direction of the rotating shaft.

In the card reader of the present invention, the retaining member for preventing the rubber ring from coming off from the core member in the axial direction of the rotating shaft is formed separately from the transport roller and the rotating shaft, and is formed in the radial direction of the rotating shaft. It is attached to the core member or the rotating shaft from the outside of the. Therefore, in the present invention, after assembling the transport roller in a state where the retaining member is not attached (that is, after fitting the rubber ring to the core member), the core member or the rotating shaft is attached from the outside in the radial direction of the rotating shaft. It becomes possible to attach a retaining member. Therefore, in the present invention, even if the rubber ring can be easily fitted to the core member when assembling the transport roller, the retaining member prevents the rubber ring from coming off from the core member in the assembled card reader. It becomes possible to do.

Further, in the present invention, since the retaining member is attached to the core member or the rotating shaft from the outside in the radial direction of the rotating shaft, the retaining member is attached to the core member or the rotating shaft even when the transport roller is attached to the rotating shaft. It becomes possible to attach a member. Therefore, in the present invention, for example, after a card reader to which a retaining member is not attached is installed on the market, when there is a need to prevent the rubber ring from coming off the core member, the transport roller is rotated. It is possible to attach a retaining member to the core member or the rotating shaft without removing it from the shaft. As a result, in the present invention, for example, even when the retaining member is retrofitted to a card reader installed on the market without the retaining member attached, the retaining member can be easily attached. Become.

In the present invention, for example, the retaining member connects two retaining portions arranged so as to sandwich the rotating shaft and one ends of the two retaining portions, and at least one of the core member and the rotating shaft. It is provided with a fixed portion fixed to one side, and the shape of the retaining member when viewed from the axial direction of the rotating shaft is a C shape or a U shape.

In the present invention, the retaining portion is preferably formed in a flat plate shape which is arranged so as to face the end face of the rubber ring. With this configuration, the retaining portion formed in the shape of a flat plate can effectively prevent the rubber ring from coming off the core member.

In the present invention, the card reader includes a main body frame on which a card carrying path is formed, the retaining member is arranged on one side of the rubber ring in the axial direction of the rotating shaft, and the main body frame has the axial direction of the rotating shaft. It is preferable that the wall surface is arranged on the other side of the rubber ring and faces the end face of the rubber ring. With this configuration, the wall surface formed on the main body frame makes it possible to prevent the rubber ring from coming off from the core member on the other side in the axial direction of the rotation shaft. Therefore, it is possible to simplify the configuration of the card reader as compared with the case where the retaining members are arranged on both sides of the rubber ring in the axial direction of the rotating shaft.

In the present invention, it is preferable that the retaining member is fixed to the core member and the rotating shaft by a screw for fixing the core member to the rotating shaft. With this configuration, when the retaining member is fixed to the core member and the rotating shaft by a fixing means provided separately from the screw for fixing the core member to the rotating shaft, or when the core member is attached to the core member. A fixing means provided separately from the screw for fixing to the rotating shaft makes it possible to simplify the configuration of the card reader as compared with the case where the retaining member is fixed to the core member or the rotating shaft. Become.

As described above, in the present invention, in the card reader provided with the rubber roller having the rubber ring and the core member as the transport roller for transporting the card in the card transport path, the rubber ring can be easily used as the core member when assembling the transport roller.
