Abstract
PURPOSE:To enable to display the tape winding time and run time of remaining tape, by detecting the rotating speed of winding reel or supply reel, and making operation through the use of it. CONSTITUTION:A rotary disc 6 having a number of through-holes 7 at the external circumference is connected, and the winding reel 1 or supply reel 2 is detected with photocoupler 8 and rotating speed detection means 9 for the rotating speed. Next, this detection signal is fed to the calculation means 10 like a microcomputer. The tape winding time and run time of the remaining tape are calculated with the tape run speed which is known, hub diameter and tape thickness of the winding reel 1 and supply reel 2 based on the rotating speed supplied. Thus, the tape winding time and run time of the remaining tape can be displayed on the display means 11.
