Therefore, when the geared motor 54 rotates and the large diameter portion of the cam 53 contacts the tongue piece 51a of the leaf spring 51, the swinging member 46 rotates the shaft 41 as the center of rotation of the tension coil spring 50. It is configured to rotate clockwise in FIG. 3 against the urging force so that the contact 49 comes into contact with the upper portion of the transport roller 26. At this time, as shown in FIG. 5, the pair of arm portions 46a, 46a of the swinging member 46 causes the pinch roller 4 to move.
The contact points 49 engage with the electrodes of the IC card 10 with a predetermined contact pressure, and the pinch roller 40 functions as a stopper for stopping the rotation of the swinging member 46. .

Since the pinch roller 40 functions as a stopper in this way, a dedicated stopper is not required, so that not only the number of parts is reduced but also the structure is simplified. Further, by using the common shaft 41 as the support shaft of the bracket 42 of the pinch roller 40 and the support shaft of the swing member 46 of the contact 49, the structure is simplified. Further, by positioning the contact 49 at the same position as the axis of the shaft 23 of the transport roller 26, the card can be processed by the contact 49 at the same position as the transport roller 26.

The contact pressure to the IC card 10 by the contact 49 can be surely obtained. Further, since the cam 53 presses the bracket 46 via the plate spring 51, which is an elastic member, the tongue piece of the plate spring 51 is applied even if the pressing force of the large diameter portion of the cam 53 exceeds a predetermined value. It can be absorbed by 51a. Therefore, the pressing force of the cam 53 can be set in advance to a value larger than a predetermined value, so that the contact 4
The contact pressure of 9 can be reliably obtained.
