Abstract

PURPOSE: To design a simple running system and to control stable tape tension by controlling the braking torque applied on a reel table by the cylinder driving current detected by a detection means by a tape tension control means.
CONSTITUTION: The cylinder 4 winding a magnetic tape 3 at specific angle, the detecting means detecting the driving current of the cylinder 4, the reel table 33 engaged with the feeding reel built in a tape cassette and the tape tension control means applying a specific braking torque on the reel table 33 for giving a fixed tension to the magnetic tape 3 are equipped with. The tape tension control means gives braking torque to the reel table 33 of a feeding reel so as to make a cylinder driving current constant by the cylinder driving current detected by the detection means. Tape tension can thus be held constantly irrespective of the tape winding radius with a simple structure.
