Abstract
PURPOSE:To enable to switch the reproducing state of a tape automatically, by discriminating digital and analog signals automatically, interrupting reproducing tone for the digital signal, and rewinding the tape for reproduction. CONSTITUTION:Frequencies f1, f2 represent 0 and 1 in case of a tape reproduction signal of a digital signal. An output from a reproducing section 1 is applied to band-pass filters 2, 3 for f1, f2, and when signals of f1, f2 continue for a specified time or more at a continuous time detection circuit 8 via detection circuits 4, 5, addition circuit 6 and wave-shaping circuit 7, the circuit 8 is at high level, a return signal is applied to the reproducing section 1 via an MPU, a relay 12 turns off, and the digital signal is reproduced with interrupted unpleasant data tone. In case of analog signal, the signal is amplified 9 and speaker tone is generaged. Thus, the reproducing state is switched automatically and unpleasant data tone is interrupted.
