Filed: 1988-04-21
Abstract: PURPOSE:To successively record only the part of a bilingual broadcast by using a bilingual broadcast receiving signal when the bilingual broadcast is received, causing an electric circuit system, etc., in a recording condition to be in a temporary stopping condition when there is no bilingual broadcast receiving signal and causing the circuit system, etc., to be in the recording condition again when the bilingual broadcast receiving signal is recovered. CONSTITUTION:A bilingual broadcast receiving signal FB, out of two receiving signals, goes into a recording mode judging circuit 9 in addition to a light emitting circuit 5B and a sound signal processing circuit 6. In this judging circuit 9, a bilingual broadcast receiving signal FB' is outputted when a VTR is recorded and the signal is inputted to a logic circuit part 10. The circuit part 10 outputs a temporary stopping signal FP when there is no bilingual broadcast receiving signal or when a temporary stop commanding signal is inputted. When the signal FP is outputted from the circuit part 10, this signal is inputted to a driving device 11 which causes the electric circuit system, a cylinder, a head and a tape traveling system to be in the temporary stopping condition. Thus, when a television broadcast to be just received is not a bilingual sound signal, the VTR is temporarily stopped and when the bilingual broadcast is started, recording is restarted.
