For automatically completing insertion and ejection of a magnetic-tape-cassette into a holder, an actuating rod carries a pin which engages a slot in an insertion/ejection lever. During insertion of a cassette into a holder, pivoting of the lever causes relative movement of the pin with respect to a control edge of the slot along a first portion, and then along a second portion in which force of an ejection spring moves the actuating rod and continues pivoting of the lever to cause the cassette to move to the fully inserted position. During ejection, movement of the actuating rod moves the pin along a first stop edge portion of the slot to pivot the lever, until the spring passes an overcenter point and causes the lever to continuing pivoting and to eject the cassette.
