Abstract
PURPOSE: To detect the tape winding diameter without being affected by temperature independently of tape speed, by producing pulses in synchronizing with the rotation of a tape reel and processing them digitally.
CONSTITUTION: A pulse P1 in synchronizing with a reel at one side is generated from the 1st pulse generator 11, and the pulse P2 in synchronizing with the pulse P1 is generated from the 2nd pulse generator 12, the pulse P5 in synchronizing with the rotating body 6 turned with this tape is generated from the pulse generator 19, the pulse P5 is taken as the clock input of the counter 17 and the pulse P4 is taken as the reset input, the output of the counter 17 is taken as the data input of the latch circuit 21, the pulse P3 is input as the control input to the latch circuit 21 to obtain the tape winding diameter information as the output of the latch circuit 21.
