A device for automatically inserting and ejecting an information carrier by means of an over-center mechanism, which is actuated manually until the over-center point is reached. The over-center mechanism comprises an eccentric gear which has a diameter which increases as the insertion movement proceeds, the gear surface engaging a sliding member for the information carrier. As a result, the automatic insertion path length is increased relative to the manual insertion path length.

A device for automatic insertion and ejection of an information carrier into and out of a holder, which device comprises a carrying element which cooperates with the information carrier, a slidable drive member which is moved by the carrying element, a return spring connected to the drive member and arranged to be tensioned during insertion of an information carrier, an over-center mechanism, comprising a rotary drive member which engages the slidable drive member, and a connecting rod to which the rotary drive member is eccentrically coupled, the end of the rod which is remote from a point where said rod is coupled to the rotary drive member being guided longitudinally, and an over-center spring which exerts a biasing force on the connecting rod, which biasing force has a greater effect than that of the return spring, the over-center mechanism thereby having a latched position when it is rotated beyond the over-center point, characterized in that the rotary drive member is a disk having an external drive surface, the distance between the drive member center of rotation and the drive surface increasing in the direction in which said disc rotates during insertion, and in that the slidable drive member is a drive rod arranged to cooperate with the rotary drive member, which slidable member comprises a contact surface which engages the drive surface of the disc.
