ダ用ジャック切換回路。A recording/playback switch that selectively switches between recording and playback, a plurality of transmission gates whose operating states change depending on the switching of the previous recording/playback switch, and a phone jack whose function changes depending on the operating state of the plurality of transmission gates. In preparation, when the previous recording re-switching switch is set to the recording side, one of the plurality of transmission gates connected to the microphone side becomes conductive, and the other of the plurality of transmission gates connected to the speaker side becomes cut off. , the phone jack becomes an input jack for an external microphone, and when the previous recording/re-switching switch is set to the playback side, one of the plurality of transmission gates connected to the microphone side is cut off, and the one of the plurality of transmission gates connected to the speaker side is cut off. 1. A jack switching circuit for a tape recorder, characterized in that the other one of the plurality of transmission gates is in a conductive state, and the phone jack becomes an input jack for an earphone.
