Abstract
PURPOSE: To accurately display the remaining time of tape by backward counting the time with a back-counting circuit from the time when set value and count value coincide.
CONSTITUTION: The tape running time corresponding to the tape capacity of a cassette is set in a setter 11 and is displayed in a display device 16 by switches S1 thru S4. When the playback-recorded state is set in this state, switches S5, S6 close, causing the output of an SR type FF 17 to be inverted by the output of a trigger circuit 18 and a transistor Q1 to become OFF. Then a back counting circuit 14 counts the clocks of a reference oscillator 13 according to the output of a fast-set circuit 20. The time outputted by a decorder driver circuit 15 thereby is compared with the set time of the setter 11 and the output of the FF 17 is inverted by the coincidence signal outputted by a comparator 12, causing the transistor Q2 to conduct. Then, the output of the circuit 20 also inverts and the running of a motor 23 and the back counting of the circuit 14 are started via inverter 21 and the remaining time of the tape is accurately displayed in a display device 16
