Claims

[Scope of utility model registration request]

The sliding substrate on which the magnetic head is placed is moved to the operating position by the rotational force of the electric motor, and is also displaced from the operating position to the non-operating position, and the playback operation button is locked in the operating position. A tape recorder incorporating first and second tape recorders configured as above includes: a first electric motor incorporated in the first tape recorder; 2. A second electric motor incorporated in the second tape recorder, a second electric motor drive circuit for rotationally driving the second electric motor, and a first control that is closed when a playback operation button of the first tape recorder is in an operating position. With the switch,
A second control switch is closed when the playback operation button of the second tape recorder is in the operating position, and an H level signal is sent to one input terminal by closing the first control switch and the second control switch, respectively. the first and second N input terminals, and the other input terminal is connected to the other output terminal.
and an AND circuit, the first NAND circuit and the second
The output signal of the NAND circuit controls the operation of the second motor drive circuit and the first motor drive circuit, and also controls the operation of the first motor drive circuit.
A motor control circuit for a tape recorder, characterized in that when power is supplied when a control switch and a second control switch are in an open state, the first motor and the second motor are driven to rotate.
