<p>PURPOSE:To realize small-sized, lightweight constitution by securing mode switching by using a frequency signal which corresponds to the rotation of the rotary magnet of a motor. CONSTITUTION:Prescribed signals are supplied to the fast-forward and rewind input terminals I, FF and I, REW of an LSI75 exclusively for tape recorder control through connection terminals 761 and 762. The LSI75 outputs driving signals from its fast-forward and rewind output terminals O, FF and O, REW to driving circuits 771 and 772. Then, reel motors 44 and 56 are rotates at rotation speeds and in rotation directions which correspond to a fast-forward and a rewind state. For example, when a tape comes to its end and the motor 56 stops, a detecting circuit 80 detects the absence of a signal FG from an FG pattern 53 for a prescribed time, and then outputs a driving signal to a mode switching mechanism 81.</p> |
