<p>PURPOSE:To prevent a miss such as double recording in repeat operation by resetting a recording operation part every time tape run directions are changed over with regard to a control signal for tape run direction switching. CONSTITUTION:When forward-directional recording is carried out with the recording state set in both forward and reverse directions and a magnetic tape almost comes to the end, an inversion control signal inputted to terminal A and an output from output terminal Q of FF8 are both held at level H and inputted to AND circuit 13 and switch SW1 interlocking with forward recording button 2B is opened by resetting method 15, thereby resetting the forward recording. Next, when the tape comes to the end in the reverse direction, the output of FF8 is inverted in response to the inversion control signal and switch SW2 interlocking with reverse recording button 2B is opened by resetting method 16 to open SW1 and SW2, so that change-over method 12 will change the electric circuit to the reproduction state. Thus, double recording in repeat operation can be prevented.</p> |
