音再生操作切換回路。[Scope of Claim for Utility Model Registration] In a cassette deck for performing recording and playback operations, A. n operation buttons provided on the operation panel for operating the cassette deck, and B. n operation buttons to display the operation buttons. An operation display board consisting of m sets of two display boards provided at corresponding positions to selectively display a playback operation display and a recording operation display, and an output of one of the operation buttons described above. A set consists of two units that receive signals at the same time, and consists of n sets.
A control circuit that inputs the output signal of the AND circuit and generates a desired output signal.E A control circuit that is manually operated when the cassette deck is used for recording, and is operated by a permanent magnet.
A recording operation selection switch consisting of a repulsion coil type switch that self-holds itself by magnetic adsorption force and automatically releases the self-holding by energizing the solenoid; F A stop operation switch; G A stop operation switch. A signal is input by operating the operation switch, and a pulse output signal is generated after a certain period of time, and if any one of the n operation buttons mentioned above is pressed within the specified period, the pulse output signal is output after the specified period of time. The above-described time constant circuit or power input detection circuit is composed of: a time constant circuit that cancels the operation to generate an output signal; a power input detection circuit that generates a pulse signal when the H power switch is pressed and conductive; 1. A recording/playback operation switching circuit characterized in that when a pulse signal is generated, a pulse current is applied to a solenoid constituting the above-mentioned recording operation selection switch so that the playback state is always returned.
