Abstract

PURPOSE: To cause the proper tension at the tape take-up side and thus secure the constant tape speed by providing the pulley in such way that the highly flexible belt may be hooked to the most outer circumference side of the tape rolled up to two reels within the cassette.
CONSTITUTION: Five units of pulley 22 are distributed within cassette 21 and hooked round with a high initial tension to the outer circumference side of the tape rolled up to each reel via thin and flexible rubber belt 23. Thus tape 24 is driven by capstan 25 and pinch roller 26 for running. Pulley 22b to which belt 23 is hooked is turned in the higher speed than the tape running via the larger diameter side of stepped pinch roller 26. In the case of the tape running inversion, pinch roller 26a is released with pinch roller 26b of the other side applied to secire the instantaneous switching. In such constitution, the instantaneous inversion can be facilitated to keep the tape tension at the constant level. Thus the tape speed can be kept constant.
