プレコーダ。 A tuner section that receives and demodulates television broadcast signals from the VHF/UHF band and/or broadcast satellite, a recording switch that selects one of the outputs of the tuner section or signals input to an external input terminal, and the output signal of the recording switch. a recording circuit section that converts the signal to be recorded on the magnetic tape, a playback circuit section that converts the playback signal of the rotary head into a video signal, and a monitor switch that selects either the output of the tuner section or the output of the playback circuit section. and a video tape recorder comprising a control section for controlling operation switching of each of the circuits, wherein a switch circuit is provided in each power supply path to the tuner section, the recording circuit section, and the playback circuit section, and the control section controls the control section. A video tape recorder characterized in that only a switch circuit that supplies power to a circuit section necessary for outputting a signal selected by the recording switch and monitor switch is rendered conductive by outputting the signal.
