<p>PURPOSE:To form a new tape recorder device in which a capstan and a pinch roller, etc. are not used, by constituting the device in such a way that an auto- reverse function can be realized. CONSTITUTION:When a tape 16a reaches its end and the rotation of a roller 14b is stopped under a tape running condition, generation of an FG pulse signal from a speed detector 14 is stopped and the output voltage level of an integration circuit 32 drops below a prescribed level. Then a switching circuit 33 set an amplifier circuit 28 to a blocked condition and interrupt the power supply to a reel motor 19 and the rotation of the reel motor 19 is stopped. If a changeover switch is switched to the auto-reverse function side when the motor 19 is stopped, a reverse-direction reproducing signal Rev is automatically outputted and the tape 16a is set to a reverse-direction reproducing condition, and thus, the auto-reverse function is performed. In this case, the amplifier circuit 28 is controlled so that it cannot be set to the shut out condition by the action of an LSI.</p> |
