Abstract

PURPOSE: To display the amount of transported tape, by obtaining the number of revolutions of reels for faster and slower reels in rotation speed and calculating this with a given equation.
CONSTITUTION: The outputs of the counters 4, 5 counting the number of revolutions of each reel are operated at the operation unit 6 based on the equation aN1+ bN2, and the amount of transported tape is displayed by driving the display unit 7 with the output. In this equation, N1 is the number of revolutions of faster reel and N2 is that of slower reel. Further, a and b are not equal and arbitrary constants which are not 0 or 1. Thus, the measurement can be made in the error within 10% for start of winding and the same amount of tape for the both reels.
