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. The system further features an additional intermittent motor drive coupling system having dormant non power-transferring condition so that accidental release of the above mentioned locking mechanism, will not cause spontaneous actuation of the cyclic actuation system.
