Abstract
Abstract A mode selector assembly for use in a tape recorder or the like is disclosed herein, for placing the tape recorder or the like into a selected operating mode by means of a rotating member upon the actuation of an actuator lever. The mode selector assembly includes a cam surface on the rotating member, interlocking device provided between the actuator lever and the rotating member for sliding movement with rotating movement of the cam surface, responsive to rotation of the rotating member and connecting means for connecting the actuator lever to the interlocking means. The actuator lever is shifted to its actuated position via the interlocking means in response to rotation of the cam surface immediately after the rotating member is rotated upon actuation of the actuator lever.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A mode selector assembly for use in a tape recorder for placing the tape recorder into a selected operating mode by means of a rotating member, upon the actuation of an actuator lever, said mode selector assembly comprising a rotating member having a cam surface, interlocking means provided between the actuator lever and the rotating member for achieving a sliding movement with the rotational movement of the cam surface, responsive to rotation of the rotating member and connecting means for connecting the actuator lever to the interlocking means, wherein upon the actuation of the actuator lever, the rotating member is rotated, and the actuator lever is shifted to its actuated position via the interlocking means, in response to the rotation of the cam surface.
Claim 2
Dependent Claim
124 words
A mode selector assembly for use in a tape recorder for placing the tape recorder into a selected operating mode by means of a rotating member, upon the actuation of an actuator lever, said mode selector assembly comprising a rotating member having a cam surface, interlocking means provided between the actuator lever and the rotating member for achieving a sliding movement with the rotational movement of the cam surface, responsive to rotation of the rotating member and connecting means for connecting the actuator lever to the interlocking means, wherein upon the actuation of the actuator lever, the rotating member is rotated, and the actuator lever is shifted to its actuated position via the interlocking means, in response to the rotation of the cam surface.
Claim 3
Dependent Claim
230 words
A mode selector assembly for use in a tape recorder for selectively placing the tape recorder into a stop or play mode which comprises, in combination a driving gear, a rotating member containing a cam gear and adapted to be brought into operational engagement with said driving gear a trigger arm adapted to be brought into and out of engagement with a portion of said cam gear, a stop arm adapted to be brought into and out of engagement with another portion of said cam gear and a play lever and a stop lever operatively communicating with said trigger arm and stop arm respectively, whereby, when operating in said stop mode, both of said play and stop levers are forced into a non-actuated position, the cam gear is in engaging relationship with the trigger arm, the driving gear is free of engagement with the rotating member and the erase and record/play heads are out of contact with the tape and, when operating in said play mode, the actuation of the play lever disengages the trigger arm from the cam gear, causing the rotating member and the associated cam gear to rotate into engagement with the driving gear which causes further rotation of the cam gear and the subsequent locking of the play lever in an actuated position with the erase and record/play heads being placed into contact with the tape.
Claim 4
Dependent Claim
230 words
A mode selector assembly for use in a tape recorder for selectively placing the tape recorder into a stop or play mode which comprises, in combination a driving gear, a rotating member containing a cam gear and adapted to be brought into operational engagement with said driving gear a trigger arm adapted to be brought into and out of engagement with a portion of said cam gear, a stop arm adapted to be brought into and out of engagement with another portion of said cam gear and a play lever and a stop lever operatively communicating with said trigger arm and stop arm respectively, whereby, when operating in said stop mode, both of said play and stop levers are forced into a non-actuated position, the cam gear is in engaging relationship with the trigger arm, the driving gear is free of engagement with the rotating member and the erase and record/play heads are out of contact with the tape and, when operating in said play mode, the actuation of the play lever disengages the trigger arm from the cam gear, causing the rotating member and the associated cam gear to rotate into engagement with the driving gear which causes further rotation of the cam gear and the subsequent locking of the play lever in an actuated position with the erase and record/play heads being placed into contact with the tape.
Claim 5
Dependent Claim
32 words
The mode selector assembly of claim 2 wherein a start spring is operatively associated with said rotating member for imparting rotation to the rotating member upon the actuation of said play lever.
