Abstract
PURPOSE:To facilitate positioning of an original by spreading a positioning sheet over the whole undersurface of a contact glass on positioning the original. CONSTITUTION:A positioning sheet 6 is connected to a mount of an exposure lamp 4 on its one end so as no to disturb the distribution of light and to winding roller on the other end. The sheet 6 is wound on a roller 7 by a spring 8 in an ordinary condition. When an exposure lamp 4 and the 1st mirror 5 move to the left direction, the sheet 6 is moved at the same speed by restoring force of a spring 8 and wound up by the roller 7, and when forwarding movement is finished and shifted to restoring movement, the sheet 6 is wound out from the roller 7 against the restoring force of the spring 8 and is installed for the contact glass 1 spread on its undersurface.
