Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
283 words
A cassette-type tape recorder comprising, in combination, first cassette receiving means, second cassette receiving means located in spaced relation to said first cassette receiving means, a first magnetic recording-playback assembly adjacent said first cassette receiving means for engagement with a cassette disposed in said first cassette assembly means, a second magnetic recording-playback assembly operatively positioned with respect to said second cassette receiving means, single drive means selectively operatively connected to said first and said second cassette receiving means, said drive means comprising a single motor rotating at a constant speed, a belt drive connected to said motor having receiving means thereupon for receiving four independent drive belts, each of said drive belts simultaneously and separately driving independently mounted slidable drive shafts, independent solenoid means operatively connected to each of said drive shafts, said solenoid means being adapted to selectively position said drive shaft into operable relationship with said tape drive shaft to energize said tape cassettes, said drive shafts being provided with Capstan idlers thereupon for selectively operably engaging drive bushings on said tape drive shafts, first mode control means for operating only said first magnetic recording-playback assembly, a second mode control means for operating both said first and said seCond magnetic recordingplayback assemblies, interlock means connected to said second mode control means for rendering said first mode control means inoperative upon utilization of said second mode control means, means interconnecting said first and said second magnetic recording-playback assemblies for permitting playback by said first magnetic recording-playback assembly and simultaneous rerecording by said second magnetic recording-playback assembly, and audio amplification means connected to said first and said second magnetic recording-playback assemblies for selectively monitoring both said first and said second magnetic recordingplayback assemblies.

A cassette-type tape recorder comprising, in combination, first cassette receiving means, second cassette receiving means located in spaced relation to said first cassette receiving means, a first magnetic recording-playback assembly adjacent said first cassette receiving means for engagement with a cassette disposed in said first cassette assembly means, a second magnetic recording-playback assembly operatively positioned with respect to said second cassette receiving means, single drive means selectively operatively connected to said first and said second cassette receiving means, said drive means comprising a single motor rotating at a constant speed, a belt drive connected to said motor having receiving means thereupon for receiving four independent drive belts, each of said drive belts simultaneously and separately driving independently mounted slidable drive shafts, independent solenoid means operatively connected to each of said drive shafts, said solenoid means being adapted to selectively position said drive shaft into operable relationship with said tape drive shaft to energize said tape cassettes, said drive shafts being provided with Capstan idlers thereupon for selectively operably engaging drive bushings on said tape drive shafts, first mode control means for operating only said first magnetic recording-playback assembly, a second mode control means for operating both said first and said seCond magnetic recordingplayback assemblies, interlock means connected to said second mode control means for rendering said first mode control means inoperative upon utilization of said second mode control means, means interconnecting said first and said second magnetic recording-playback assemblies for permitting playback by said first magnetic recording-playback assembly and simultaneous rerecording by said second magnetic recording-playback assembly, and audio amplification means connected to said first and said second magnetic recording-playback assemblies for selectively monitoring both said first and said second magnetic recordingplayback assemblies.
Claim 3
Dependent Claim
69 words
A tape recorder in accordance with claim 1, including radio receiver means for receiving a radio signal from a remote signal source, means for recording audio signals received by said radio receiver means directly onto magnetic recording tape disposed in said first cassette receiving means through said first magnetic recording-playback assembly, said radio receiver means being actuatable for direct recording through said magnetic recording-playback assembly by radio receiver means.
Claim 4
Dependent Claim
50 words
A tape recorder in accordance with claim 2, wherein auxiliary pickup means are provided for activation by a signal from a remote source distinct from said remote signal source means, and means in said first magnetic recording-playback assembly for utilizing said radio receiver means and said auxiliary input means simultaneously.
Claim 5
Dependent Claim
26 words
A tape recorder in accordance with claim 2, wherein speaker means are provided for monitoring the output of said first and said second magnetic recording-playback assemblies.
