<p>PURPOSE:To erase a music recorded incompletely by rewinding a recording side magnetic tape up to a head of a music when the tape runs to its end on the way of the music at dubbing and switching a 2nd tape recorder to the recording state. CONSTITUTION:When a detection signal is outputted from a 2nd end detection circuit 15 while a 1st no signal section detection circuit 3 detects a signal presence section, the control of operation switching circuits 12,14 for 1st and 2nd tape recorders is implemented and an output signal of control signal output terminals 20,22 goes to an L level. As a result, a switch 6 is opened, a changeover switch 8 is thrown to the position of reproduction and the 2nd tape recorder reaches the rewinding channel selection state. The reproduced signal is outputted to a 2nd no signal detection circuit 10, and when the tape is rewound up to the head of a music, a no signal section detection signal is outputted, the 2nd tape recorder is switched into the recording state, an H level signal is outputted to the control signal output terminal 22, the changeover switch 8 is thrown to the position of the recording and the recorded music is erased.</p> |
