Abstract
A switch set in the power supply section of a microphone is actuated at the initial stage of the slide of an operation button which is carried out to shift a tape recorder operation from the recording mode to the stop mode. The switch is actuated at the terminal stage of the slide of the operation button which is carried out to changeover the tape recorder operation from the stop mode to the recording mode. Therefore it is possible to eliminate the unnecessary recording in the built-in microphone of noises disagreeable to the ear of the user which are caused by, for example, the slide of the operation button.
