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.
In a motor-driven cyclic actuator for a tape player having a rotatably mounted first sector gear having at least one cutaway portion with the teeth thereof cut away, said first sector gear being rotatably mounted on a frame of said player and being coupled to reciprocatingly drive a mechanical system of said player between two positions thereof, a first drive pinion rotatably mounted on said frame and disposed to drivingly engage said first sector gear and to disengage therefrom when said cutaway portion of said first sector gear is in a position confronting said first drive pinion, releasable locking means for interceptingly arresting said first sector gear in said confronting position thereof, first rotating means for rotating said first sector gear in a given direction from said confronting position thereof to be drivingly engaged by said first drive pinion responsively to release of said locking means and for rotating said first sector gear in said given direction to said confronting position at the end of an actuation cycle so as to be captured in said confronting position thereof by said locking means, and a reciprocatingly mounted power member operably actuated by power member drive means between dormant and extended positions and coupled to operate said locking means from a locked to an unlocked state attendant to motion of said power member in an advancing direction from said dormant to said extended position thereof to initiate a cyclic drive of said first sector gear, the improvement comprising:
In a cyclic actuator for a mechanical system of a tape player having an intermittently driven rotary member mounted to a frame of said player couple to actuate said system cyclically between first and second positions thereof, locking means including a locking member operable between releasing and arresting positions for releasing and subsequently interceptingly locking said rotary member in at least one biasing means dormant non-driven position and locking member biasing means for urging said locking member to said arresting position, and a reciprocating power member having a portion thereof actuatingly coupled to said locking member and operable by power member drive means between dormant and extended positions for operating said locking member to said releasing position against the force of said locking member biasing means attendant to movement of said power member in an advancing direction from said dormant to said extended position to initiate driving of said rotary member, the improvement wherein:
In a cyclic actuator for a first mechanical system of a tape player having an intermittently driven rotary member coupled to actuate said first mechanical system cyclically between two positions thereof, locking means operable between releasing and intercepting positions for releasing and subsequently interceptingly locking said rotary member in at least one dormant non-driven position, locking means biasing means for urging said locking means into said intercepting position, and a power member having a portion thereof engagable with said locking means and operable between dormant and extended positions for operation said locking means to said releasing position attendant to movement of said power member by power member drive means from said dormant to said extended position to initiate rotation of said rotary member, said tape player further including a second mechanical system cyclically operable between first and second system positions, the improvement comprising:
