ABSTRACT:
A loading/ejection lever has a slot engaged by a pin on a servo member, for pivoting the lever during loading or ejection of a cassette. The servo member also has a guide surface for causing a cassette lift to be lowered during the latter stages of insertion, and raised during the first stages of cassette ejection. The guide surface for the cassette lift is divided into separate lowering and raising portions, arranged so that a longer stroke of the servo member is utilized during the loading process, before the cassette lift is lowered, than in the reverse movement in which the lift is raised only after the servo member has passed the lowering point. As a result of this construction, it is possible to provide a greater distance between the lever pivot and the location where the coupling pin on the servo member engages the lever, and to provide a spring element on the lever which biases the coupling pin during only a portion of the range of engagement between the servo member and the loading/ejection lever.
