Abstract
The sheet clamp apparatus is for clamping a sheet of original paper, recording paper, photosensitive paper, master plate, or the like on a drum usually provided in facsimile apparatus, copying apparatus, or the like. The apparatus comprises a single plate-shaped clamp member positioned along a generating line of the drum and at a part of the peripheral surface of the drum. The single clamp member presses firmly both the front edge and the rear edge of a sheet against the drum. The front edge of the sheet is clamped with the drum being stopped at a predetermined position, and the rear edge of the sheet is clamped after the drum has made about one revolution from the predetermined position of the front edge where the sheet is clamped.
