Abstract
A tape tension regulator automatically adjusts for minute variations of tension which are inevitably imposed upon a wound tape during its procession, thereby ultimately reproducing information having high picture quality and good sound quality. The tape tension regulator includes a guide roller having a fixing shaft and upper and lower flanges, a minute tension arm one end of which is connected to the fixing shaft of the guide roller, and the other end of which is connected to be rotatable around an arm-fixing shaft, a minute tension spring connected to a portion of the minute tension arm and a wire pole positioned in the opposite side of the minute tension spring with respect to the minute tension arm for retaining a belt-type wire in cooperation with the lower flange of the guide roller.
