Abstract
Abstract A tape recorder with improved cue and review operations is disclosed, wherein there is provided a cue/review engagement part which is engageable with a rotary shaft supporting an idler wheel and is capable of moving said rotary shaft so as to separate the idler wheel from a take-up reel when high speed rewind or fast/forward is desired and the engagement part is also engageable with a pinch roller actuator for disengaging the pinch roller from pressing the tape during cue or review operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A tape recorder having a first lever for actuating a normal play mode and a second lever for actuating fast forward/cue modes, the tape recorder comprising: a chasis; a take up reel block rotatably mounted on said chasis; a head base slideably mounted on said chasis; an idler wheel shaft slideably coupled to the chasis; an idler wheel rotatably mounted on the idler wheel shaft; a rotational power source means mounted on said chasis; and engagement means for actuating the fast-forward/cue modes; where the rotational power source means normally engages the idler wheel and the idler wheel normally engages the take up reel block when the first lever is fully actuated; and wherein the engagement means for actuating the fast forward/cue modes is engageable with the idler wheel shaft and capable of separating the idler wheel from the rotational power source means when said second lever is partly actuated, thereby breaking a path of power transmission from the rotational power source means to the take up reel block by way of the idler wheel.
Claim 2
Dependent Claim
174 words
A tape recorder having a first lever for actuating a normal play mode and a second lever for actuating fast forward/cue modes, the tape recorder comprising: a chasis; a take up reel block rotatably mounted on said chasis; a head base slideably mounted on said chasis; an idler wheel shaft slideably coupled to the chasis; an idler wheel rotatably mounted on the idler wheel shaft; a rotational power source means mounted on said chasis; and engagement means for actuating the fast-forward/cue modes; where the rotational power source means normally engages the idler wheel and the idler wheel normally engages the take up reel block when the first lever is fully actuated; and wherein the engagement means for actuating the fast forward/cue modes is engageable with the idler wheel shaft and capable of separating the idler wheel from the rotational power source means when said second lever is partly actuated, thereby breaking a path of power transmission from the rotational power source means to the take up reel block by way of the idler wheel.
Claim 3
Dependent Claim
83 words
A tape recorder according to claim 1 further comprising: a capstan shaft rotatable on said chasis; a pinch roller actuator pivotably mounted to said read base; and a pinch roller, rotatably mounted on the pinch roller actuator and engageable with said capstan shaft, said pinch roller being normally biased against said capton when the normal play mode is actuated; wherein said engagement means is engageable with the pinch roller actuator and capable of separating the pinch roller from the capstan during cue/review operations.
Claim 4
Dependent Claim
38 words
A tape recorder according to claim 1 wherein said rotational power source means comprises; a power shaft rotatably coupled to the chasis; a bush for engaging with the idler wheel fixed to one end of said power shaft.
Claim 5
Dependent Claim
28 words
A tape recorder according to claim 3 further comprising a rewind arm pivotably mounted to the chasis where said power shaft is rotatably mounted through said rewind arm.
Claim 6
Dependent Claim
37 words
A tape recorder according to claim 1 having a second path for transmitting rotational power from the rotational power source means to the take up reel block, where said idler wheel constitutes a first power transmission path.
Claim 7
Dependent Claim
29 words
A tape player according to claim 5 wherein said rotational power source means comprises a power shaft, and wherein second path comprises gear means mounted on said power shaft.
