うにしたことを特徴とするテープレコーダーの誤
動作防止回路。 It has a recording switching signal output terminal that outputs a switching signal that puts the tape recorder into a recording state when a switching signal is input to the recording input terminal, and an IC-based operation circuit, and a switch from the playback side to the recording side during recording operation. A recording/playback selector switch that is switched, and when the record/playback switch is switched from the playback side to the recording side, or from the recording side to the playback side, it operates in reverse, and when it is on the recording side, it connects to the recording input terminal of the operating circuit. A switching transistor inputs a switching signal, and is biased by a switching signal outputted from a recording switching signal output terminal of the operating circuit and inverted to a conductive state, and is biased when the switching transistor is in a switching signal input state. The reset transistor is in a non-conducting state when the voltage is cut off, and when the switching signal is not input to the recording input terminal and the switching signal is output to the recording switching signal output terminal, the reset transistor is turned off. A malfunction prevention circuit for a tape recorder, characterized in that the operating circuit is reset by conduction.
