<p>PURPOSE:To prevent the generation of resonance by fixing a tension arm with a pressing spring by pressure-fitting it with a loading block. CONSTITUTION:At a tape unloading position a tension arm 22 is energized in a clockwise direction via a 2nd tension plate 26 by the energizing force of a pressure spring 23 and the loading block 3 located at the front side of a guide groove 2 is fixed with its pressure fitting to the front side end part of the guide groove 2 by the pressure part 22b of this arm 22. in this case, a link plate 27 is located at the end part in the rotating direction of a clock side, consequently a 1st tension plate 25 is located at the most left side position of the figure and the fear of the resonance of the loading block 3 is eliminated. The loading block 3 is therefore not abutted with the edge of the guide groove 2 and the durability of the device is not reduced.</p> |
