Abstract

PURPOSE:To avoid the constraint of a video tape and to realize long time video recording by detecting the end of one video video tape, outputting an end signal, and inputting this end signal as a start signal into another video tape. CONSTITUTION:A video signal from the input terminal 5 of a first video tape recorder VCR is sent to a picture recording circuit part 3, and a switch 8 is set to recording. When a start signal is inputted from an input terminal 11, the tape is driven by a driving circuit part 4 and the video signal is recorded by the circuit parts 3 and 4. When the video tape ends, the end signal is outputted to a terminal 10 by an end signal generating part 9. This end signal is inputted into the terminal 11 of a second VCR as the start signal, and the video signal is recorded by the circuit parts 3 and 4 of the second VCR. Thus, another VCR is not actuated until the end signal is outputted from VCR, and therefore, the video recording time is prevented from being restricted by the VCR tape and long time video recording can be realized.
