PURPOSE:To achieve easy replacement of information sheets, by clipping an information sheet between a flexible base sheet and a transparent sheet freely removably. CONSTITUTION:Winding frames 3a and 3b are fixed to a rotary shaft 2 of a sheet-containing case 1, and one end of a purality of sheets 4, 4,... is fitted in parallel with the shaft 2 between the winding frames 3a and 3b with fitting members 5, 5,.... The members 4 consist of a flexible base sheet 6 and a transparent cover sheet 7 overlapped closely with the sheet 6. A flexible information sheet 8 is closely clipped between the sheets 6 and 7. The sheet 8 is clipped by closely overlapping the sheet 7 again after the sheet 7 is opened and inserted. Thus, the cover 7 is opened and the sheet 8 is taken out and replaced with other sheet 8 freely. |
