Abstract
PURPOSE: To stabilize the run of a tape by applying tension to the tape by braking a tape-advance-direction conversion roller by a detection arm when tape tension from a tape supply side is below a fixed value.
CONSTITUTION: When tape tension is small while a tape is being driven in recording or reproduction mode, braking parts 16 and 17 of tension detection arms 10 and 11 come in contact with tape-advance-direction conversion rollers 7 and 8 by elastic forces of springs 18 and 19 as shown in the figure, inhibiting those rollers 7 and 8 from turning. Therefore, tape 4 is tensed by fraction force generated through the sliding of rollers 7 and 8, and, in consequence, tape 4 runs stably. In fast-winding or rewinding mode of tape 4 or in case of the generation of an abnormal load, on the other hand, tape 4 increases in tension to turn tension detection arms 10 and 11 against the forces of springs 18 and 19, and braking parts 16 and 17 separate from rollers 7 and 8, smoothing the fast-winding and rewinding of tape 4.
