PROBLEM TO BE SOLVED: To improve assembly efficiency by simplifying the structure. SOLUTION: A front shutter (100) is attached to an upper cover (50). Spindle holes (51-R and -L) through which the points of a rotating spindle of the front shutter are inserted are provided at the attachment ends of the front panel on both the side faces (50-R and -L) of the upper cover. A principle plane (50-M) has a tongue-shaped latch (52) obtained by bending a part around the side end of the front through which a flexible disk is inserted and retreating the part, and the front shutter has a projection (102) located at the position corresponding to the tongue-shaped latch around the side end of the rotating spindle and for latching the front shutter on the tongue-shaped latch by rotating force given by an unillustrated coil spring. In this structure, the front shutter is located so as to close most of the front of the upper cover. No clasp-shaped mold on which the end of the coil spring is hung and no frame hole for the clasp- shaped mold are necessary. COPYRIGHT: (C)2004,JPO
