Abstract: An intermittently driven cyclic drive member for operating a system of a tape player between a plurality of operative positions thereof includes a quick-return lock for re-establishing a locking position with respect to the drive member. The quick-return lock is actuated to a released position during only the initial movement of a power plate, returning immediately thereafter to an intercepting position and remaining positively fixed there throughout the entire remainder of the actuation stroke of the release member. Provision is further made to couple the locking system of the present invention to a second system of the player, as for example a drive disconnect plate, so that the aforementioned unlocking condition cannot be established unless the second system is properly positioned.

Abstract: An eject mechanism for ejecting automatically the tape cassette in a tape player, in which one of two switching gears disposed on both the sides of a gear plate and engaging with a forward/backward rotating gear is selectively engaged with an intermittent gear by said forward/backward rotating gear and said intermittent gear drives the driven mechanism for the eject operation, said intermittent gear being so constructed that it is locked only in the forward rotational direction.

Abstract: An ejection mechanism for a tape player includes a guide arm vertically movably supporting a pack guide, a pack stopper connected to the guide arm for frontward and rearward movement, an ejection link connected to the guide arm, and an inversion spring provided connecting the pack stopper to the ejection link to draw and eject a cassette. The ejection mechanism further includes an ejection member disposed along a lateral wall of the frame and mounted for frontward and rearward movement and biased forward by first revival spring, and an operation member similarly disposed alongside the ejection member and similarly mounted for frontward and rearward movement with respect to the frame and biased forward by second revival spring, and an operation rod coupling the ejection link to the motion operation member. An automatically releasing latch couples the ejection member to the operation member during the inward stroke of the ejection member.
