<p>PURPOSE:To perform a tape guide on the upstream side of the running tape at the time of recording and reproducing modes. CONSTITUTION:The tape guides 6 holding arms 3 and rollers 4 between are provided on a pair of left/right pinch roller arms 3 on a chassis freely rotatably to a fulcrum shaft 7 so as to energize toward capstan shafts 2. A projecting part 6b faced downward is provided on each tape guide 6 in addition to guide parts 6a of the tape T. Stopper receiving parts 8 are provided near the capstan shafts 2 on the chassis. At the recording/reproducing times, the pinch arm at the right side is pushed and rotated by an erecting part 11a of a lever 11 through a spring member 5, and the pinch roller 4 is pressed in contact with the capstan shaft 2, but further, the rotational fulcrum of tape guide is moved by the rotation of pinch arm and retreated with rotation by taking the receiving part 8 as the fulcrum, then the guide parts 6a are placed on the positions not in contact with the tape.</p> |
