<p>PURPOSE:To prevent a tape running system from stopping on the way of the switching of a running state, by providing an off detecting and holding part and an FF part that detect the off state of a switching element which is interlocked with a rapid traverse/rewinding button, and holds it for a reulated time. CONSTITUTION:At the time of a rapid traverse/rewinding operation, when the second switching element 3 interlocked with the rapid traverse/rewinding button is turned off, the fact is detected by an off detecting and holding part 11, and the output of the holding part 11 becomes high for the regulated time. In such case, a time while the high level of the part 11 is kept, is set as a little longer than the time from when the output of a motor driving part 7 becomes low, and the power source of a motor 8 is turned off, until when the rotation of the motor 8 stops actually. And when a play button is depressed after the rapid traverse/rewinding is removed in a high level time, and before the rotating speed goes to zero, the motor 8 is driven again through an FF13, and the motor 8 stops after the first running system 9 goes to a playing state completely. In this way, the running state of the tape running system 9 is prevented from stopping on the way of the switching, and inconvenience, such as a state impossible to take out the tape, can be eliminated.</p> |
