Abstract

PURPOSE:To automatically open or close an original press-contacting plate and permit sure press-contacting of thick originals as well by combining the original press-contacting plate which is rotatable and is vertically movable and a driving source. CONSTITUTION:An original press-contacting plate 3 having an elastic original press-contacting member 4 is rotatable around a turning shaft 8, and is vertically movable along a guide 5. Hence, when a thick original is placed on an original placing plate 2, the place 3 can conform to the thickness of the origonal. The leading end of the plate 3 is engaged to the leading end of a frame member 9 turning around a turning shaft 10, by means of an engaging pin 12. This member 9 is driven by a motor 14 via a crank mechanism to perform opening or closing operation. According to this, the plate 3 makes opening or closing operation as well. In this way, thick originals such as a book are surely press-contacted by automatically opening or closing the original press-contacting plate.
