Abstract: This invention provides an IC card processing apparatus in which a contact error does not occur in contact elements even when a warped card is inserted, and the service life of the contact of the contact elements can be prolonged. When an IC card 1, 1′ is inserted to the deep end, the distal end of a second arm 42 of a pivot lever 40 abuts against the upper surface of a contact element block 50, to regulate the contact element block to swing about a fulcrum on a line almost perpendicularly intersecting one surface of the contact element block 50 and extending through almost the center of a contact element group, or a support axis perpendicularly intersecting this line, as the center. Therefore, the contact pressures between the respective contact elements 51 of the contact element block 50 and the respective contacts of the IC card 1, 1′ become almost equal to each other.
