Abstract
PURPOSE: To display the tape length after using and to enable to display the residual amount of tape by time, by detecting the number of revolutions of winding side reel and performing operation with a given condition.
CONSTITUTION: The tape T from the supply side reel 1, ro in radius, is wound on the winding reel 2, ro in radius, through the magnetic head 3. In this case, taking that the total length of tape as L, thickness of tape as t, amount of run of tape when the reel 2 is turned by n as l, and the tape speed as S, the relation of l= πtn2+(2πro+πt)n is established, and the residual time of tape is (L-l)/S (second). Accordingly, the number of revolutions n of the reel 2 is detected 20 and the operation 26 is made by using the constant (t, L, ro, S) set 30 to the memory with the keyboard, then the tape length l after using can be obtained by decimal number and this can be displayed 27.
