DEVICE FOR DUBBING OF VCR

摘要

PURPOSE: A dubbing device of VCR is provided to use an acoustic signal as it is and to dub only an image signal in editing a VCR. CONSTITUTION: A key signal corresponding to an image editing mode is inputted through a key inputting unit(18) when a user needs to maintain an acoustic signal and to displace only an image. A VCR mechanism is controlled to perform a general recording function and the acoustic signal before recording is played from a playing head(10). Every signal recorded in a tape is erased. A microcomputer controls to record an outer video signal through the general recording function. Only the acoustic signal is demodulated through a demodulating unit(12) and a time is delayed by a time delaying unit(14) when a sound is played through the playing head(10). The microcomputer(16) erases only a signal of audio track after recording the image signal through the VCR head by outputting a control signal to an audio erasing head(26). The acoustic signal outputted from the signal delaying unit(14) is transmitted to an audio R/P head(24) by passing a modulating unit(22).
