HEAT-TRANSFER INK SHEET CASSETTE

PURPOSE:To prevent adherence of fine dusts to an ink sheet and to obtain a high printing quality by so covering a cassette housing with a shielding member formed of a flexible material as to open or close the opening f the housing. CONSTITUTION:After all sheets are used, a cassette housing 1 is reused, and only an ink sheet 3, a supply reel 2 and a takeup reel 4 are replaced. When the sheet 3 is replaced, an upper housing 1A is removed, and a supply reel 2 and a takeup reel 4 for a new ink sheet 3 are mounted. In this case, fine dusts 8 on the upper face 7 of a desk are shielded by a shielding member 18. Then, when it is set in a printer, the housing 1A is coupled to a lower housing 1B, and the hole 20 of the material 18 is engaged with the hook 21 of the housing 1A. In this case, the dusts 8 adhered to the member 18 are interposed between the housing 1B and the member 18 without scattering externally. Accordingly, the dusts are not externally scattered, thereby to obtain a high printing quality without contaminating of a printed surface.
