Title:
FLOPPY DISC CASSETTE
Document Type and Number:
Japanese Patent JPS58122678
Kind Code:
A
Abstract:
PURPOSE:To improve the positioning accuracy and to eliminate tracking error, by providing a mechanism giving a load to a position where a force exerting to a floppy disc advances to the region formed by two places to which a rotary shaft and positioning holes are butt-engage and the center of the rotary shaft. CONSTITUTION:One end of a dust removal mechanism 8 having an elasticity being a load to the floppy disc 3 is fixed to a cassette shell 1 and the other end contacts a magnetic substance plane of a magnetic sheet 4. A grating projection 9 is formed to the cassette shell 1 opposing to the mechanism 8 is formed and the sheet 4 runs between the both by being depressed with the projection 9 at the mechanism 8 to remove dusts. In the region of two points being press-coupling of the rotary shaft R and a hole 6, a force to the floppy disc 3 is exerted.
