A presser 7 is provided and both are bridged by a spring body 8.

The insertion hole through which the shaft 20 of the planetary roller 6 is inserted is formed in an oval shape instead of a perfect circle, and the pusher 7 is slightly displaced in accordance with the displacement of the planetary roller 6 and has a spring member having an electric contact 15. It is designed so that a substantially uniform pressing force can be obtained. Further, one end of the spring body 8 is press-fitted into a small hole formed in the peripheral wall of the pressing element 7, and the other end is pressed against the peripheral wall of the planetary roller 6. The small hole portion of the spring body 8 can be fixed by caulking.

The gear 4 is pivotally attached to the shaft 1 so as to be rotatable, and a notch is formed in a boss portion thereof. A pin 9 is provided upright on the shaft 1 at a position where the notch is located. The shaft 1 rotates when the pin 9 is in contact with the edge of the notch, and the pin 9 Does not rotate when is not in contact with the edge of the notch.

A cylinder having a female hole corresponding to the thread groove formed in the center hole is screwed into the cylindrical body 3, and a rubber,
The card feed roller 10 is formed by sticking, crimping or integrally molding a cylinder or ring formed of soft plastic or the like. A stopper (not shown) is formed at one end of the tubular body 3 so that the card feeding roller 10 does not fall out of the tubular body 3 when the card feeding roller 10 rotates and moves to that portion. Is done.

The gear meshes with a gear 11, which is fixed to a shaft 12. A drive roller 14 is provided at a portion of the shaft 12 facing the planetary roller 6 with a slight gap between the IC card 13 and the planetary roller 6 when the IC card 13 is not inserted in the apparatus.

On the other hand, an arm 16 is provided on the pusher 7 side, and one end of the arm 16 is pivotally attached to a shaft 17. The arm 16 is integrally formed of an insulating material, and a spring member having an electric contact 15 is fixed to the arm 16 by tacking, screwing, or the like, and connected to a data processing device (not shown) through a lead wire for drawing. There is. Although not shown, the arm 16 is urged upward by the pressing member 7 side by a spring, a leaf spring or other elastic member. The tubular body 3 is made of a metal material, but is made of rubber or a plastic material, and when a torque of a certain value or more is applied to the shaft 1, the shaft 1 continues to rotate, but the tubular body 3 Alternatively, it is possible to press-fit with an appropriate crimping force so as to stop the rotation.
