A magnetic tape reproducing and/or recording system in which two magnetic cassette tape transports are mounted on the same chassis and are adapted to selectively drive magnetic tape from two separate type cassettes past separate head assemblies to reproduce and/or record magnetic signals on the tape. The arrangement is such that the second tape cassette is automatically actuated upon the tape in the first cassette reaching its end, and vice versa. Logic circuitry is provided which controls the tape transports so that, after completion of the first cassette tape it can be rewound to a starting position during play of the second tape, and vice versa. A single set of recording and playback electronics can be provided which are automatically switchable between the respective head assemblies depending on the particular operational mode.
A tape cassette deck comprising a first means on said chassis for receiving a first tape cassette, second means on said chassis for receiving a second tape cassette, first transport means on said chassis and operable in a first mode in which it unwinds the tape of said first cassette from its supply hub to its takeup hub at a constant speed and in a second mode in which it rewinds said tape from its takeup hub to its supply hub at a relatively fast speed, second transport means mounted on said chassis and operable in a first mode in which it unwinds the tape of said second cassette from its supply hub to its takeup hub at a constant speed and a second mode in which it rewinds said latter tape from its takeup hub to its supply hub at a relatively fast speed, sensing means for responding to either one of said transport means completing its unwinding mode for generating an output signal, control means connected to said sensing means and to said first and second transport means for switching the other of said transport means to its unwinding mode and for switching said one transport means to its rewinding mode in response to said generation of said output signal.
A tape cassette deck comprising a chassis, first means on said chassis for receiving a first tape cassette, second means on said chassis for receiving a second tape cassette, a first head assembly on said chassis and associated with said first means for engaging the tape of said first tape cassette, a second head assembly on said chassis and associated with second means for engaging the tape of said second tape cassette, first transport means on said chassis and associated with said first means for unwinding and rewinding the tape of said first cassette relative to said first head assembly, second transport means mounted on said chassis and associated with said second means for unwinding and rewinding the tape of said second cassette relative to said second head assembly, sensing means for responding to the cessation of motion of one of the hubs of said first cassette as a result of the tape of said first cassette completely unwinding from said hub for generating an output signal, and control means connected to said sensing means, said control means being responsive to said output signal for activating said second transport means.
A tape cassette deck comprising a chassis, first means on said chassis for receiving a first tape cassette, second means on said chassis for receiving a second tape cassette, a first head assembly on said chassis and associated with said first means for engaging the tape of said first tape cassette, a second head assembly on said chassis and associated with second means for engaging the tape of said second tape cassette, first transport means on said chassis and associated with said first means for unwinding and rewinding the tape of said first cassette relative to said first head assembly, second transport means mounted on said chassis and associated with said second means for unwinding and rewinding the tape of said second cassette relative to said second head assembly, sensing means for responding to the tension of the tape of said first cassette resulting from the latter tape completely unwinding from its corresponding hub for generating an output signal, and control means connected to said sensing means and to said first and second transport means, said control means being responsive to said output signal for activating said second transport means.
