<p>PURPOSE:To make a device small sized, thinner and light weighed and to reduce the number of parts by laminating a pair of loading rings of a loading device in the height direction. CONSTITUTION:A pair of toggle links 12, 13 are provided in place of a pair of loading rings of a loading device to support respective slider 10, 11. The toggle links 12, 13 are formed by two links 12a, 12b and 13a, 13b respectively, linked rotatably by shafts 14, 15 respectively and sliders 10, 11 are loaded on one end of the rings 12a, 13a. Posts 18, 19 are planted as well respectively at the intermediate part of the rings 12a, 13a and engaged with a pair of the oblong holes 3c formed at both sides of a reel base 3. The rings 12a, 13a are energized by turning in the inside direction by the spring provided on the shafts 16, 17. The loading ring couple is then laminated in the height direction to make the device small sized, thinner and light weighed.</p> |
