<p>PURPOSE:To repeat hearing of orally recorded sentences easily by a few device operations, by providing a means to stop the tape running when sound pause information is detected. CONSTITUTION:When a head 30 comes to the position of (c), a sentence end sign 29a is detected. Then a flag check circuit 15 is put into operation to check a flag circuit 14. A repeat control circuit 21 emits a tape stop signal to a tape driving and controlling circuit 22 to stop the tape temporarily, simultaneously setting the flat circuit 14 to 1. Suppose the value of a counter in a counting circuit 20 is smaller than, or equal to, the value of a repeat counter 19. In this case, L signal is issued, and the repeat control circuit 21 gives a retreat signal to the tape driving and controlling circuit 22, and, at the same time, sends a level adjusting signal to a playback circuit 12, start level check circuit 11, and level check circuit 10. Thus, the tape runs backwards.</p> |
