Abstract

PURPOSE:To apply transistor (TR) switching by using a detection signal both a recording mode detection switch and a reproducing mode detection switch so as to control a power control circuit of a built-in microphone thereby abolishing a changeover switch for a built-in microphone recording and a dubbing recording. CONSTITUTION:In throwing an interlocked recording-reproduction changeover switch 14 to terminals (d, f) to activate the built-in microphone 1, a built-in microphone TR 10 is turned off and a TR 4 is turned on, then a voltage is applied to the built-in microphone 1, which is operated. In this case, a monitor control TR 19 is turned on at the same time and the output signal is muted. In turning on a reproduction detection switch 13 built in a reproduction tape mechanism to change over the mode from the built-in microphone recording tinto a dubbing recording next, the TR 10 is turned on, the TR 4 is turned off, no voltage is applied to the microphone 1, which is inactivated.

FIG. 2 shows a conventional built-in microphone control circuit. In order to operate the built-in microphone 1, voltage is applied to the built-in microphone 1 by turning on the recording system changeover switch 3, which switches between built-in microphone recording and dubbing recording, to the 4 terminal, and turning on the recording-playback changeover switch 7 to the h terminal. In addition, built-in microphone 1 operates. At this time, the monitor control transistor 10 is also turned on at the same time, and the output signal is muted.
