Abstract
A card reader includes an IC contact block having IC contact springs, a main body frame and a torsion coil spring which urges the IC contact block. The IC contact block has a card abutting part abutting with a card and a block side spring engaging part with which one end of the torsion coil spring is engaged and is movable between a contact position where the IC contact springs are contacted with the card and a retreated position where the IC contact springs are retreated from the card. The main body frame has a frame side spring engaging part with which the other end of the torsion coil spring is engaged. The torsion coil spring urges the IC contact block toward the retreated position and, when the IC contact block is pushed by the card, the IC contact block is moved from the retreated position against the torsion coil spring.
