Claims

[Scope of utility model registration request]

A first operation switch group that is operated in connection with various operations such as playback, and command signals are input to each input terminal by operating the first operation switch group, and the first tape is input by inputting each command signal. The first step sets the drive mechanism section to an operating state corresponding to each command signal.
An operation circuit, a second operation switch group that is operated in conjunction with various operations such as recording and playback, and command signals are input to each input terminal by operation of the second operation switch group, and each command signal is inputted to each input terminal. The second
A second operation circuit sets the tape drive mechanism to an operating state corresponding to each command signal, and commands the playback input terminal of the first operation circuit and the recording and playback input terminals of the second operation circuit during a dubbing operation, respectively. A dubbing command circuit outputs a signal, and a command signal is sent to the recording input terminal of the second operating circuit upon detecting that the erroneous recording prevention claw of the cassette attached to the second tape drive mechanism has been removed. a detection switch that prevents input from being input; and a stop input terminal of each of the first and second operation circuits when the detection switch detects that the erroneous recording prevention claw is removed during dubbing operation. and a stop command circuit that outputs a command signal to each of the tape recorders.
