摘要
PROBLEM TO BE SOLVED: To effect an automatic insertion and push out of an information card to and from a card connector device at comparatively slow and nearly constant speed for a whole stroke. SOLUTION: The card connector device is composed of a conveyor device for conveying an information card inserted from an insertion opening up to a connection position coming in connection with a contact, and conveying the information card at connection position from the insertion opening to an ejecting position protruding outside. A drive control device of a card-insertion and push- out motor 33 is composed of a voltage switch control device which makes control of voltages supplied to the motor into high and low steps and a torque detecting device for detecting torque generated by the card-insertion and push- out motor. The voltage switch device changes voltage supplied to the card- insertion and push-out motor over to high voltage when torque detected by the torque detector gets over a certain value, and down to low voltage when the torque gets under a certain value.
