Abstract

PURPOSE: To stabilize each control system and to stabilize the whole controlling system, by detecting tape wind radius of reels and then by applying detection outputs to a tape tension controlling system and tape speed controlling system.
CONSTITUTION: For example, the tape wind radius of supply reel 2 is denoted as r1cm, the rotational period as T1 seconds, and the tape speed as (v) cm/second, so that T1=2πr1/v second. On the other hand, the number of pulses generated during the single rotation of roller 10 is denoted as F while the radius of roller 10 rotated as tape 1 is wound as r2cm, so that F=vxp/2πr2/second. Therefore, the number of pulses F' generated in T1 seconds is shown by expression I. Namely, pulse number F' during the single rotation of supply reel 2 is in proportion to tape winding radius r1cm of supply reel 2. For this purpose, tape wind radiuses of take-up reels 2 and 4 are both detected and obtained signals are applied to the tape tension and speed control circuit to correct fluctuations of the function of the tape winding radius, so that the whole controlling system can be stabilized.
