PURPOSE:To easily position a copying original by strippably attaching a transparent sheet on the jointed face applied to a light transmitting plate, and holding an original sheet between said jointed face and said sheet. CONSTITUTION:A transparent sheet 6 is strippably attached to the jointed face 5 of an original cover plate 4, and the sheet 6 is made of a highly transparent and flexible sheet material, such as transparent soft PVC sheet. One end of it is pasted to the side end of the plate 4 for pivotably supporting it by means of bonding, and ferromagnetic metal plates 7a, 7b, and 7c are pasted to the other side ends of the sheet 6. Rubber magnet plates 8 are pasted to the side ends of the plate 4 except the side end of said pivotal support, and the magnet plates 8 attract the plates 7 magnetically to fix the sheet 6 to the plate 4 strippably. |
