ダーの制御回路。[Claims for Utility Model Registration] When a fast forward or rewind operation is performed from the playback state, the fast forward or rewind operation is performed without canceling the playback state, and the fast forward or rewind operation button is moved to the operating position by the suction action of the plunger. hold on. In a tape recorder configured to detect a non-signal between signals of music or the like recorded on a magnetic tape, the plunger is brought into a non-suction operation state, and thereby switched to a playback state. a no-signal portion detection circuit that is activated by a music selection switch that is switched during operation and outputs a high-level signal, and also outputs a low-level signal when the no-signal portion is detected; A high level signal is applied as a base bias to turn on the plunger, and the driving transistor is connected to the plunger as a load, and the plunger is inserted into the power supply path and is connected to the driving transistor, which is connected to the plunger as a load, and is connected to the driving transistor, which is connected to the plunger as a load, and is connected to the driving transistor, which is connected to the plunger as a load. A control switch that is closed during a rewinding operation, a closing time control switch of the control switch that accompanies a fast forwarding or rewinding operation when the song selection switch is open, and a current flowing through the coil of the plunger. A control circuit for a tape recorder comprising a control transistor that is biased into an on state and maintains the driving transistor in a reverse biased state.
