Abstract

PURPOSE: To control the tape running surely based on sure tape position display, by electrical display of the revolution of the reel stand through reversible count and controlling the next operation mode according to the present operation mode for the output of the display means.
CONSTITUTION: Revolution of the winding reel 1 is detected with the two sets of Hall elements 3 and 4, the direction of revolution discriminating circuit 5 discriminates the direction of rotation of the stand 1 with the phase comparison of detected pulse, the up and down counter 6 counts reversibly the number of detected pulses of the element 3, and the tape position is surely displayed on the display unit 8 even at fast feed. When the switch S1 is closed, the counter 6 is reset and the display is also zeroed, and the logic discrimination circuit 9 controls the next operation mode in response to the present operation mode depending of the count content of the counter 6 zeroed. For example, in rewinding mode at present, the circuit 9 produces the stop instruction, the counter 6 counts a given number with over running due to inertia, and when the counter 6 is again reset, the play mode instruction is made to correctly stop the tape at a given location.
