Abstract

PURPOSE:To stop the operation of a television tuner not required when the VTR section is at the reproduction mode, to reduce power consumption and to extend the service life of a battery when available by stopping the power supply to the television tuner with a reproduction mode output signal from the VTR section. CONSTITUTION:The power is supplied to the VTR section 3 and the television monitor section 4 via a main switch 6 from a power supply section, and the power to the television tuner section 2 is via a subswitch 7. The subswitch 7 is controlled by a reproducing mode output signal 8 from the VTR section 3. The output of the subswitch 7 is 0V when the VTR section 3 is at the repro duction mode and the signal 8 goes to 1 (or H) through the opening state of the switch 7, and the reproduction mode output signal goes to 0 (or L) in other modes, the switch 7 is closed and the output of the switch 7 is V volt.

From each part L! Since power is supplied to I, 1B+, and i41 without distinction, when the VTR section (3) mentioned above is in the playback mode, the TV tuner section (2) does not operate even though only the playback video signal is output. , the video signal from the TV tuner section is input to the VTR section (3), but it is completely wasteful (particularly in the case of a battery-operated VTR with a TV set, the battery is wasted). The present invention was made in order to solve the above-mentioned problems, and it provides a VTR with a TV that eliminates wasteful consumption of power source power and can extend the life of the battery if the power source is a battery. The purpose is to obtain.
