Abstract
PURPOSE: To calculate the total required running time of a tape by running the tape for a short time at a constant speed, calculating and storing the revolving periods of a feed reel and a take-up reel at the respective times of that time and calculating and storing the tape thickness therefrom.
CONSTITUTION: A revolving period measuring means 5 calculates the revolving periods of respective reels by the instructions from a take-up reel revolution detecting means 3, and a feed reel revolution detecting means 4. Memories 7, 6, 8 store the feed reel revolving period at the time t0, the feed reel revolving period at the time t0+Δt and the revolving period of the take-up reel at the time t0, respectively. A tape thickness calculating means 9 makes calculations based on these and stores the values into a memory 10. A tape total required running time calculating means 13 makes calculations based on the values from the memories 10, 7, 8 and dispalying is made in a display device 14.
