<p>PURPOSE:To make increase of a driving force of a reel unnecessary without applying a useless load by releasing a pre-load brake, at the time of play, by placing the pre-load brake and a reel brake in the inside and the outside of a fast forward gear and a rewinding gear, and also, constituting them so that they are controlled by a separate control constitution, respectively. CONSTITUTION:At the time of play, a loading motor is rotated from a state that tape loading is completed, and a pinch roller is pressed against a capstan. At the same time, the first control plate 6 is driven in the upper direction, a take-up gar 5 is engaged to a winding reel 2 and a center gear 3 by an energizing force of a spring 7a, both of them are connected, the winding reel 2 rotates through the center gear 3 and the take-up gear 5, and a tape run is executed. In such case, the first control plate 6 is in the upper side, and the first brake release plate 18 is in the right side, therefore, a pre-load brake 16 turns to the center position and fixed to the same position, and a connecting gear 7 for fast forward and rewinding is also held in the center position.</p> |
