<p>PURPOSE:To improve the reliability of operation by adopting the constitution that flicker display is attained until the speed is made stable when the tape running speed is changed over at dubbing so as to allow the user to confirm immediately the state thereby preventing mis-operation. CONSTITUTION:In operating a speed changeover switch 72 included in a speed control section 7, a command is outputted from a control circuit 71 to a prescribed time generating section 9, and a pulse is outputted for a prescribed time until the tape running speed is made stable from the prescribed time generating section 9 receiving the command and inputted to a control circuit 81 included in a speed display section 8. Further, the speed switching commend from the 1st to the 2nd speed is outputted from the control circuit 71 to the control circuit 81 included in the speed display section 8. The control circuit 81 extinguishes the 1st speed display element 82 while receiving the said command, flickers the 2nd speed display element 83 during a prescribed time outputted from the prescribed time generating section 9 and lights it after a prescribed time is elapsed.</p> |
