Abstract
Abstract A magnetic record/playback apparatus has a head plate and a control plate which are disposed on a tape deck slidably movable in forward and rearward directions. A head is fixed on the head plate and a changeover mechanism for putting a tape driving system selectively into a cue scanning mode is engaged by motion of the control plate. The head plate is formed with an elongated slot extending in the displacement direction of the plates and the control plate is provided with a pin slidable within the elongated slot. The control plate is engaged by a scanning mode operating rod for displacing the control plate forwardly to put the system into normal play or scanning mode and rearwardly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
291 words
In a magnetic tape playback apparatus for sensing beginning-of-music cues in a cue-scanning mode, said apparatus including a tape cassette support means comprising supply and take-up reel-receiving means, and fast forward and rewind drive means selectively driving said supply or take-up reel-receiving means at a fast speed during said cue-scanning mode or for normal fast forward and fast rewind of the tape, the improvement comprising: a head support member having a magnetic head thereon and displaceable conjointly over a given distance with said magnetic head between a first position where said head is pressed snugly against the tape for normal play to a second position where the head is pressed in light contact with the tape for cue-scanning; tape running means including means for engaging and driving said tape at a normal play speed and movable between a first tape engaging and driving position to a second tape disengaging position where said take-up reel-receiving means is driven at a high cue-scanning speed; a control member for controlling the position of said engaging means of said tape running means and displaceable over a distance greater than said given distance and between a first position where said tape running means is in said first tape engaging and driving position to a second position where said tape running means is in said second position disengaged from said tape; and manually operable setting means for controlling the positions of said head support and control members and movable over a given distance from an initial playback operating position where said head support and control members are in said first positions to a cue-scanning position where said head support and control members have moved different distances into said second positions for effecting a cue-scanning mode of operation.

291 words
In a magnetic tape playback apparatus for sensing beginning-of-music cues in a cue-scanning mode, said apparatus including a tape cassette support means comprising supply and take-up reel-receiving means, and fast forward and rewind drive means selectively driving said supply or take-up reel-receiving means at a fast speed during said cue-scanning mode or for normal fast forward and fast rewind of the tape, the improvement comprising: a head support member having a magnetic head thereon and displaceable conjointly over a given distance with said magnetic head between a first position where said head is pressed snugly against the tape for normal play to a second position where the head is pressed in light contact with the tape for cue-scanning; tape running means including means for engaging and driving said tape at a normal play speed and movable between a first tape engaging and driving position to a second tape disengaging position where said take-up reel-receiving means is driven at a high cue-scanning speed; a control member for controlling the position of said engaging means of said tape running means and displaceable over a distance greater than said given distance and between a first position where said tape running means is in said first tape engaging and driving position to a second position where said tape running means is in said second position disengaged from said tape; and manually operable setting means for controlling the positions of said head support and control members and movable over a given distance from an initial playback operating position where said head support and control members are in said first positions to a cue-scanning position where said head support and control members have moved different distances into said second positions for effecting a cue-scanning mode of operation.
Claim 3
Dependent Claim
54 words
The magnetic tape playback apparatus of claim 1, further wherein said manually operable setting means includes a search mode actuating push rod which moves at all times with said control member and which is connected to said control member through a slot in said head support member to form a lost motion connection therebetween.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein said head member and said control member are configured as generally planar plates disposed in parallel contiguous relationship.
Claim 5
Dependent Claim
153 words
The magnetic playback apparatus according to claim 1, wherein said head support member has at one end portion thereof an elongated slot and at the opposite end portion thereof a through aperture, said control member having a receiving aperture opposite to said aperture thereof, and said setting means includes: a push-rod fixed to said control member; a pin affixed to said push-rod and disposed to slide within said elongated slot, and said tape running means comprises: at least one motor driven capstan shaft; at least one pinch roller manually mounted in a pinch roller mount pivotally supported on said head member to place said roller selectively attached to or spaced from capstan shaft; and a tractive rod affixed to said control member and passing through said through aperture for pivoting said at least one pinch roller mount between capstan tape pressing engaging and disengaging positions in response to movement of said control member.
Claim 6
Dependent Claim
41 words
The magnetic tape playback apparatus of claim 1 wherein said head support member and said control member have apertures therein for allowing the reel-receiving means to extend therethrough in all of said position of said head member and said control member.
Claim 7
Dependent Claim
37 words
The apparatus according to claim 5, wherein there is provided idler means movably engageable by said control member and adapted to be pressed against at least one of said reel-receiving means and rotated by a motor drive.
Claim 8
Dependent Claim
124 words
The apparatus of claim 1 wherein said setting means includes a lost motion actuator means operated by a single movable member and selectively coupling said head support member and said control member so that by operating said movable member to a first position thereof said head support member and said control member are disposed in said first positions thereof, by operating said movable member from the first position thereof to an intermediate position thereof only said control member is moved from the first position thereof to an intermediate position thereof, and so that by operating said movable member from said intermediate position thereof to a second position thereof said head support member and said control member are collectively moved to said second position respectively.
Claim 9
Dependent Claim
38 words
The apparatus of claim 7 wherein said head support member and said control member are cconfigured as generally planar plates, and one of said head support member and said control member slidably supportingly engages the other of same.
