Claims

[Scope of utility model registration request]

(1) If you press the fast forward 7 rewind button while playing the first cassette tape, the first cassette mechanism will be in the fast forward 7 rewind state while this button is pressed and will return to the playback state when you release the button, and a motor that drives a first cassette tape;
In a double cassette tape recorder comprising a second cassette mechanism for recording playback signals from the first cassette tape onto a second cassette tape and a motor for driving the second cassette tape, the second cassette mechanism is in recording operation. , and a switching circuit that turns off the power of the motor that drives the second cassette tape when a fast forward 7 rewind button of the first cassette mechanism is pressed during playback of the first cassette tape. A pause circuit for a double cassette tape recorder characterized by providing the following.

(2) A first transistor connected in series to the power supply circuit of the motor that drives the second cassette tape, a second transistor connected between the base of the first transistor and ground, and a first cassette connected to the base of the second transistor. A request for registration of a utility model, characterized in that a switching circuit is configured to turn off the power of the motor that drives the second cassette tape by means of supplying a signal indicating that the fast forward and rewind buttons of the mechanism have been pressed. A pause circuit for a double cassette tape recorder according to item 1.
