Abstract

Abstract A cartridge locking and ejector mechanism for use in a tape player includes a pivotally mounted ejector arm movable from a first to a second position and resiliently biased to the first position. A linkage includes a first arm mounted for pivotal movement about a first point and engageable with the ejector arm, a second arm pivotal about the same point and having a projection extending into the path of a cartridge received in the tap player and a third arm pivotally mounted on the first arm and releasably interconnecting the first and second arms. A cartridge inserted into the player engages the projection, causing the linkage to move the ejector arm to the second position whereat a solenoid operated latching assembly secures the ejector arm. Further insertion of the cartridge to its fully inserted position in the player, disconnects the first and second arms permitting the second arm to move with the cartridge. Upon reaching a fully inserted position in the player, a spring biased roller is received in a notch in the cartridge wall to maintain the cartridge secured in the player. Deenergization of the solenoid releases the ejector arm, causing the ejection of the cartridge from the player.

Claim 8
Dependent Claim 275 words
A cartridge locking and ejector mechanism for a tape player using an exchangeable cartridge, including in combination: a pivotally mounted ejector arm movable from a first to a second position; biasing means resiliently biasing said ejector arm to said first position; means for retaining said ejector arm in said second position, linkage means comprising a first arm mounted for pivotal movement about a fixed pivot point and having a portion thereof in engagement with said ejector arm, a second arm mounted for pivotal movement about said fixed pivot point and including a first projection extending into the path of a cartridge received in said player and a second projection extending adjacent said first arm and a third arm mounted on said first arm for pivotal movement with respect thereto, said third arm receiving said second projection of said second arm to removably interconnect said first and second arms, said first projection of said second arm being engaged by a cartridge inserted into said player to rotate said first arm, thereby to in turn rotate said ejector arm against said biasing means to said second position, said first and second arms being disconnected from each other subsequent to the movement of said ejector arm to said second position and in response to the full insertion of said cartridge into said player; and means for engaging said cartridge to maintain the latter in a fully inserted position in said player upon insertion of said cartridge to said fully inserted position, said retaining means being releasable to permit movement of said ejector arm from said second to said first position, thereby to eject said cartridge from said player.
