Abstract

Abstract A housing for an electronic-type tape player device has two substantially perpendicular and intersecting outer walls, one of which includes an access opening to an internal cartridge receiving cavity and the other of which contains thereon an actuator member for a tape cartridge ejection mechanism. The actuator member is movable to an actuated position and is linked to an actuated member internal to the housing for correspondingly moving the actuated member. The actuated member is engageable with a bi-stable cartridge lock and release mechanism for moving the same from a first stable cartridge lock position to a second stable cartridge release position with movement of the actuator member to its actuated position thereby to permit an insertable tape cartridge to be removed from the cavity.

Claim 4
Dependent Claim 52 words
The ejection mechanism of claim 1 wherein said pivotal member comprises a pivotal bell crank mechanically coupled to said second member and having a pivot axis removed from said mechanical coupling to provide movement of said first member in said one direction with movement of said second member in said other direction.
Claim 5
Dependent Claim 265 words
In an electronic-type tape player device including a housing having two substantially perpendicular and intersecting outer walls, an opening in one of said outer walls providing access to an internal cartridge receiving cavity, a bi-stable cartridge lock and release mechanism operable in a first plane between first and second stable positions by a snap-acting overcenter means for locking a tape cartridge within said cavity in said first position and for releasing said cartridge for removal from said cavity in said second position, an ejection mechanism including in combination: a linearly actuable slide member having an actuator arm extending outwardly of said player device from the other of said two outer walls, said actuator arm being movable in a second plane generally perpendicular to the plane of movement of said lock and release mechanism for providing movement of said slide member to an actuated position, a cam means internal to said housing and movable in said first plane, said cam means being engageable with said lock and release mechanism for moving the same from said first stable position to cause said overcenter means to move said lock and release mechanism to said second stable position with a snap-acting movement whereby said tape cartridge is released, and a motion converting means including a member mounted on said housing for pivotal movement and coupled pivotally to said slide member and link means coupled to and interposed between said pivotally mounted member and said cam means for converting movement of said slide member in said second plane to a corresponding movement of said cam means in said first plane.
Claim 6
Dependent Claim 265 words
