Abstract
Abstract In a combined phonograph record player and recorder having a first device operative to play a phonograph record and a second device, such as, a tape recorder, operative to record on a magnetic tape the content of a phonograph record being played by the first device; elements are provided for detecting a halt in the operation of either one of the devices, for example, the completion of the playing of the phonograph record or the lifting of the stylus therefrom prior to the completion of the playing thereof, or the interruption of the driving of the tape in the tape recorder, such as, by reason of the willful stopping of the tape driving or the automatic stopping of the tape driving due to the exhaustion of the supply of tape in the recorder, and the detection of a halt in the operation of either one of the devices causes a halt in the operation of the other of the devices.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
248 words
The combination of a phonograph record player including a rotary turntable for carrying a phonograph record having a record groove with signals recorded in the latter, a pickup having a stylus engageable with the record groove for tracking the latter and reproducing the signals recorded therein, a tone arm carrying said pickup and being movable for lowering and raising said stylus into and out of contact, respectively, with the phonograph record and for said tracking of the record groove by said stylus when the latter contacts the phonograph record, and means actuable for lifting said tone arm to raise said stylus out of contact with said phonograph record and thereby halt the tracking of said record groove by said stylus and the reproducing of said recorded signals by said pickup; a magnetic tape recorder for recording the signals reproduced by said pickup on a magnetic tape and including drive means operative to drive said tape during the recording of said signals thereon, and means actuable for halting the operation of said drive means so as to stop the recording of signals on said tape; detecting means for detecting a halt in the operation of said drive means during the recording by said magnetic tape recorder of the signals being reproduced by said pickup and the phonograph record player; and control means actuating said means for lifting said toNe arm in response to the detection by said detecting means of said halt in the operation of said drive means.
Claim 2
Dependent Claim
248 words
The combination of a phonograph record player including a rotary turntable for carrying a phonograph record having a record groove with signals recorded in the latter, a pickup having a stylus engageable with the record groove for tracking the latter and reproducing the signals recorded therein, a tone arm carrying said pickup and being movable for lowering and raising said stylus into and out of contact, respectively, with the phonograph record and for said tracking of the record groove by said stylus when the latter contacts the phonograph record, and means actuable for lifting said tone arm to raise said stylus out of contact with said phonograph record and thereby halt the tracking of said record groove by said stylus and the reproducing of said recorded signals by said pickup; a magnetic tape recorder for recording the signals reproduced by said pickup on a magnetic tape and including drive means operative to drive said tape during the recording of said signals thereon, and means actuable for halting the operation of said drive means so as to stop the recording of signals on said tape; detecting means for detecting a halt in the operation of said drive means during the recording by said magnetic tape recorder of the signals being reproduced by said pickup and the phonograph record player; and control means actuating said means for lifting said toNe arm in response to the detection by said detecting means of said halt in the operation of said drive means.
Claim 3
Dependent Claim
127 words
The combination according to claim 1; in which the magnetic tape is wound on and extends between supply and take-up reels, and said drive means is operative to drive the tape from said supply reel toward said take-up reel and to rotate the latter for winding the tape thereon; and in which said detecting means includes switching circuit means having one state in response to rotation of said take-up reel and another state when rotation of the take-up reel is halted, and said means for lifting the tone arm includes a solenoid connected with said switching circuit means and having one state in response to said one state of the switching circuit means and another state in response to said other state of the switching circuit means.
Claim 4
Dependent Claim
72 words
The combination according to claim 1; further comprising second detecting means for detecting the lifting of said tone arm during said recording by the magnetic tape recorder of said signals being reproduced by the pickup of said phonograph record player; and second control means actuating said means for halting the operation of said drive means in response to the detection by said second detecting means of said lifting of the tone arm.
Claim 5
Dependent Claim
38 words
The combination according to claim 3; further comprising deactivating means for the first mentioned control means and said second control means to permit operation of said phonograph record player and said magnetic tape recorder independently of each other.
Claim 6
Dependent Claim
49 words
The combination according to claim 3; in which the magnetic tape is wound on and extends between supply and take-up reels, and said drive means is operative to drive the tape from said supply reel toward said take-up reel and to rotate the latter for winding the tape thereon.
Claim 7
Dependent Claim
81 words
The combination according to claim 5; in which said means for halting the operation of said drive means includes a first stop mechanism for automatically stopping said drive means when the tape is fully unwound from the supply reel and wound on said take-up reel, a second stop mechanism for manually stopping said drive means at will, and a third stop mechanism for causing said drive means to pause in its operation so long as said third stop mechanism is actuated.
Claim 8
Dependent Claim
33 words
The combination according to claim 6; in which said second control means includes means for actuating said third stop mechanism when said second detecting means responds to said lifting of the tone arm.
Claim 9
Dependent Claim
84 words
The combination according to claim 7; in which said means for lifting the tone arm includes a first lifting mechanism for automatically lifting the tone arm and returning the latter to a rest position upon the completion of the playing of a phonograph record, a second lifting mechanism which is manually actuable at will for lifting the tone arm and returning the latter to said rest position, and a third lifting mechanism which is manually actuable at will for merely lifting the tone arm.
Claim 10
Dependent Claim
94 words
The combination according to claim 8; in which said second detecting means includes switch means having one state when said tone arm is lowered to engage said pickup stylus with the phonograph record and another state when said tone arm is lifted, and said means for actuating said third stop mechanism includes a solenoid connected with said switch means and having one state, when said switch means is in said one state, and another state for actuation of said third stop mechanism when said switch means is in said other state of the latter.
Claim 11
Dependent Claim
