Abstract
A card holder has a frame which is rectangular in configuration with one open end through which a card can be inserted into and removed from the holder. A slide plate is slidably mounted in the frame. When the card is inserted into the frame, it slides along the slide plate and comes to a position where it abuts against a stop ridge formed along the inner edge of the slide plate. With insertion of the card into the holder, the slide plate is driven by the card further into the holder. With such motion of the slide plate, a spring connected thereto at one end and to the holder at the other end is brought to a retracted or loaded position. The spring and card are retained in the retracted position by a retainer detent formed in the holder which latches onto the slide plate and retains the slide plate in position. A manual release button mounted in the frame is used to release the detent from the slide plate, thereby freeing the slide plate and permitting the spring to drive the slide plate and along with it the card to an extended position, with the card out of the holder where it can be inserted into a gate control device for actuating such device.
