<p>PURPOSE:To listen to the whole recorded contents, by generating a control signal when a tape makes the round after start of reproducing, and automatically stopping the tape or emitting an electronic sound by utilizing said control signal. CONSTITUTION:A pulse generated from a pulse generating device 1 by rotation of a reel when reproducing a tape is counted by an up-down counter 4. An operation start signal is applied from an input terminal S, and the regular operation is started. By a tape running direction controlling circuit 2, the running direction of the tape is inverted twice, and after that, when contents of the counter 4 become a numerical value ''0'', a control signal is outputted to an output of a buffer circuit 5. By this control signal, a tape reproducing state stop device 6 is started. and the tape reproducing state is stopped automatically.</p> |
