<p>PURPOSE:To simplify the constitution by making one circle execute each function of terminal detection and intermusic detection, by means of switch of the oscillation period and the reset input. CONSTITUTION:When switches S5, 6 are turned on and a high speed reproduction is ready, the output of a voice amplifier 8 is shaped by the transistor (TR)30, 31, and is delivered to a resetting circuit 17. On the other hand, the oscillation period of an oscillating circuit 15 is quickened by separating the capacitor C33b from the C33a, and the operation is shortened comparing with the time for detecting the terminal of a tape. And, when the S6 is opened, the FF1 is inverted by a trailing pulse of the electric power source of the FF2, the TRs 7 and 3 are turned on, and the recorder is shifted to the regeneration state automatically. Also, the S34 and S35 are switched in the reproduction state, and the fast forwarding mode, etc., the output from a terminal detecting circuit 18 is applied to the circuit 17, the C33a and the C33b are connected in parallel, and the device is automatically stopped at the terminal of a tape.</p> |
