It can be transported the distance of 2). Thus, the information can be accessed by the magnetic head 16 from the front end to the rear end of the card 2, that is, over the entire length of the card 2 (the length along the card transport direction). Then, the leading end of the card 2 is conveyed until it strikes a stopper 18 having a C-shaped cross section fixedly provided on the rear side of the casing 1, and then the flat type motor 10 is reversed to move the drive pulley 7 to the first position. The card 2 is returned to the insertion slot 3 by reversing it in the direction of the dashed arrow shown in FIG. 1, and the card 2 is ejected.

Although the magnetic card is described in the present embodiment, the present invention is not limited to the magnetic card, and can be applied to a card reader / writer for an optical card that optically accesses information by using an optical head instead of the magnetic head. . Although the round belt 11 which is stretched between the pulleys 7 and 8 is used as the endless conveyor, the invention is not limited to the above embodiment, and for example, a pair of endless conveyor drive rollers may be arranged in the conveying direction. The present invention is also applicable to a type in which the drive rollers are provided separately from each other, and an opposing pressing roller is provided for each drive roller, the drive rollers are connected by a transmission belt, and each drive roller is driven by a drive motor.

[Effects of the Invention] According to the present invention, as described above, the card can be nipped and conveyed by the elastic deformation of the counter pressing roller for conveyance in cooperation with the endless conveyor, and therefore the shaft of the counter pressing roller for conveyance can be conveyed. Position the core within the range of 1/2 of the nip width in the card insertion direction from the center of the information access head, and immediately press the rear end of the card for conveyance immediately after the rear end of the card passes through the center of the head of the information access head. Since the roller can be elastically deformed to be clamped between the endless carrier and the card, sufficient information can be accessed over the entire length of the card, and the card rear edge can be clamped while the card tip hits the stopper. In this way, the card can be carried out in the reverse direction without providing another counter pressing roller for conveyance for nipping the front end side of the card. In addition, since the tip of the card does not rush into between the other conveying pressing roller for conveyance and the endless conveyance body during information access, there is no influence of large disturbance of jitter on information access.
