Abstract
Abstract A control circuit for use in the record mode in a cartridge type tape player-recorder includes a sensor for sensing the conductive strip conventionally provided on a multi-track recording tape to define the ends of the tape tracks, for the purpose of energizing a relay which disables the tape drive motor to discontinue the recording process. A program switch connected to the circuitry may be positioned so that the tape drive is disabled in accordance with the sensing of the conductive strip, subsequent to the recordation of information on each set of tape tracks making up a recording channel or subsequent to the recordation of information on a set of tape tracks making up a predetermined one of the recording channels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
257 words
A cartridge type tape player-recorder for playing and recording information on the multi-track tape in a tape cartridge, a predetermined number of said tracks comprising a recording channel, said tape including a predetermined number of recording channels, each said tape including a tape portion at a predetermined location thereon defining the relative ends of the tracks on the tape, said player recorder comprising, in combination; a magnetic tape head mounted for engagement with said tape for recording information thereon, tape head indexing means for moving said tape head incrementally from recording channel to recording channel along a path adjacent said tape, tape drive means engageable with said tape for propelling the latter through said cartridge past said tape head, sensing means for sensing said tape portion, said tape head indexing means in response thereto moving said tape head to a successive channel and tape drive shut-off circuit means coupled electrically to said sensing means and said tape drive means, said circuit means including a programing switch movable to first and second settings, said circuit means being operable when said programing switch is in said first setting, in response to the sensing of said tape portion, to disable said tape drive means regardless of the recording channel with respect to which said tape head is moved, and when said programing switch is in said second setting, in response to the sensing of said tape portion, only while said tape head is positioned with respect to a predetermined one of said recording channels, to disAble said tape drive means.
Claim 2
Dependent Claim
257 words
A cartridge type tape player-recorder for playing and recording information on the multi-track tape in a tape cartridge, a predetermined number of said tracks comprising a recording channel, said tape including a predetermined number of recording channels, each said tape including a tape portion at a predetermined location thereon defining the relative ends of the tracks on the tape, said player recorder comprising, in combination; a magnetic tape head mounted for engagement with said tape for recording information thereon, tape head indexing means for moving said tape head incrementally from recording channel to recording channel along a path adjacent said tape, tape drive means engageable with said tape for propelling the latter through said cartridge past said tape head, sensing means for sensing said tape portion, said tape head indexing means in response thereto moving said tape head to a successive channel and tape drive shut-off circuit means coupled electrically to said sensing means and said tape drive means, said circuit means including a programing switch movable to first and second settings, said circuit means being operable when said programing switch is in said first setting, in response to the sensing of said tape portion, to disable said tape drive means regardless of the recording channel with respect to which said tape head is moved, and when said programing switch is in said second setting, in response to the sensing of said tape portion, only while said tape head is positioned with respect to a predetermined one of said recording channels, to disAble said tape drive means.
Claim 3
Dependent Claim
88 words
A cartridge type tape player-recorder as claimed in claim 1 wherein tape portion comprises an electrically conductive strip and wherein said sensing means comprises a three element electrode mounted for engagement with said tape, whereby the passage of said conductive strip in engagement with said elements completes a first circuit between first and second ones of said elements, thereby to actuate said tape head indexing mechanism and a second circuit between said second and a third one of said elements to actuate said tape drive shut-off circuit means.
Claim 4
Dependent Claim
125 words
A cartridge type tape player-recorder as claimed in claim 1 wherein said shut-off circuit means includes a relay connected to said sensing means operable to disable said tape drive means upon being energized, said relay being energized in response to the passage of said tape portion past said sensing means and wherein said programing switch, in said first setting, actuates a holding circuit to said relay each time said tape portion is sensed, whereby said tape drive means is disabled in response to any sensing of said tape portion, and in said second setting, actuates a holding circuit to said relay only when said tape portion is sensed and while said tape head is positioned with respect to a predetermined one of said recording channels.
Claim 5
Dependent Claim
137 words
A cartridge type tape player-recorder as claimed in claim 3 further including channel indicator means coupled to said tape head indexing means for operation therewith, said indicator means including switch means having a plurality of positions equal in number to the number of recording channels on said tape, said switch means being movable incrementally to corresponding ones of said positions in accordance with the movement of said tape head from channel to channel, whereby said indicator means indicates the channel being recorded, said switch means being connected electrically to said programing switch and upon the latter being operated to said second setting and the former being moved to a predetermined position corresponding to a predetermined one of said recording channels, said switch means actuating said holding circuit for said relay, thereby to disable said tape drive means.
Claim 6
Dependent Claim
39 words
A cartridge type tape player-recorder as claimed in claim 4 further including automatic shut-off indicator means connected to said relay and operable in response to the energization of said relay to indicate the cessation of the recording of information.
