A sliding member 130 is slidably provided to a housing base 110, and this sliding member 130 is biased forward by a tension spring 170. When the insertion of an IC card 2 is complete, a toggle device 160 keeps the sliding member 130 locked against the biasing force of the tension spring 170. An electromagnetic solenoid 190 attracts a movable magnet core 155 forward when current is supplied, and causes a second arm 150 to swing so that a protrusion 163 on the toggle device 160 is pressed to the left by a protrusion 153. As a result, the above-mentioned lock hold provided by the toggle device 160 is released, and the sliding member 130 is slid forward by the biasing force from the tension spring 170, ejecting the IC card 2.
