<p>PURPOSE:To prevent a spring from dropping out, to simplify the constitution of a cassette holder and to facilitate to attach the spring by disposing an engaging part on a press spring and disposing a spring inserting part and plural engaging parts on a cassette holder. CONSTITUTION:The press spring 24 shaped in a leaf spring is inserted in inserting parts 27 and 28 constituted of proper gaps formed by a bent part 25 and a cut and stand-up part 26 constituted of two or more bent parts on an attaching part 23 of a sheet metal. And by making both shoulder parts of projecting piece 29 on a leading edge abut on the side wall of the cut and stand-up part 26, and engaging an engaging piece 30 with a recessed part 31 to be connected on the attaching part 23, the press spring 24 is prevented from dropping out in the direction opposite to the inserting direction. Thus, the leaf spring 24 can be attached by use of a minimum number of parts and also the press spring 24 can be detached if necessary, so that repairs and replacement can be facilitated.</p> |
