Abstract

Abstract First and second operating members can reciprocate in parallel to each other. When the first operating member moves one reel shaft rotates at high speed in the tape-winding direction. When the second operating member moves the other reel shaft rotates at high speed in the tape-winding direction. A tape-direction-changing piece can reciprocate in parallel to the first and second operating members, and can also rotate. When the first or second operating member moves, the tape-direction-changing piece rocks to allow the movement of the first or second operating member. When both the first and second operating members move at the same time, the tape-direction-changing piece moves together with the two operating members to press an operating force-transmitting member, prevented from rocking, thereby actuating a tape-feed-direction-changing mechanism.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 304 words
A tape recorder apparatus having a housing to which are mounted a magnetic head, two spaced reel shafts, means to engage said magnetic head with magnetic tape, means to drive said magnetic tape as it is engaged with said magnetic head to recore/reproduce signals, means to drive said magnetic tape at high speed, and means for changing tape feed direction, said apparatus comprising: first operating member means mounted to said housing and selectively manually movable for reciprocating relative to said housing between its rest position and an actuating point along a given line to actuate said high speed tape driving means for one reel shaft when it reaches said actuating point; second operating member means mounted to said housing and selectively manually movable for reciprocating relative to said housing between its rest position and an actuating point along a line parallel to said given line to actuate said high speed tape driving means for another reel shaft when it reaches said actuating point; resilient means to bias said first and second operating member means away from said actuating point and toward said rest position; a tape-direction changing piece mounted to said housing for pivotal and linear movement relative thereto, said first operating member means pivoting said piece, exclusive of said second operating member means, in one direction of rotation when it advances along said given line to the actuating point, said second operating member means pivoting said piece, exclusive of said first operating member means, in the other direction of rotation when it advances along said parallel line to said actuating point, said first and second operating member means when moved together to an intermediate point between the rest position and said actuating point causing said piece to linearly move parallel to said given line to actuate said means for changing tape feed direction.
Claim 2
Dependent Claim 304 words
A tape recorder apparatus having a housing to which are mounted a magnetic head, two spaced reel shafts, means to engage said magnetic head with magnetic tape, means to drive said magnetic tape as it is engaged with said magnetic head to recore/reproduce signals, means to drive said magnetic tape at high speed, and means for changing tape feed direction, said apparatus comprising: first operating member means mounted to said housing and selectively manually movable for reciprocating relative to said housing between its rest position and an actuating point along a given line to actuate said high speed tape driving means for one reel shaft when it reaches said actuating point; second operating member means mounted to said housing and selectively manually movable for reciprocating relative to said housing between its rest position and an actuating point along a line parallel to said given line to actuate said high speed tape driving means for another reel shaft when it reaches said actuating point; resilient means to bias said first and second operating member means away from said actuating point and toward said rest position; a tape-direction changing piece mounted to said housing for pivotal and linear movement relative thereto, said first operating member means pivoting said piece, exclusive of said second operating member means, in one direction of rotation when it advances along said given line to the actuating point, said second operating member means pivoting said piece, exclusive of said first operating member means, in the other direction of rotation when it advances along said parallel line to said actuating point, said first and second operating member means when moved together to an intermediate point between the rest position and said actuating point causing said piece to linearly move parallel to said given line to actuate said means for changing tape feed direction.
Claim 3
Dependent Claim 26 words
The tape recorder apparatus according to claim 1, wherein said first and second operating member means and said tape-direction-changing piece are arranged one above the other.
Claim 4
Dependent Claim 137 words
The tape recorder apparatus according to claim 1, wherein said means for changing tape feed direction includes a driving gear supplied with a rotary force from a reel driving motor, a changing gear having two pause portions cut in the tooth region thereof so as to be symmetrical with respect to the center of rotation thereof, one of the pause portions retaining the changing gear in a position facing the driving gear, retaining means for releasing the changing gear from retention to cause the same to mesh with the driving gear when the means for changing tape feed direction moves together with the first and second operating member means, and means for changing the tape-feed direction by rotating the changing gear to shift relative positions of two pinch rollers and their corresponding capstans for engagement or disengagement.
