PURPOSE:To prevent miscopy due to the positional shift of an original placement by providing a light-permiable original pressing plate with the light permiable property at the normal operation or also copying operation. CONSTITUTION:Sectional views indicating normal operation and copying operation are shown. A power supply line to the inside of an original cover plate body 1 is drawn into the body 1 and rollers 5, 6 are fitted to both the ends of the inside of the body 1. A sheet obtained by connecting white sheet parts 3a, 3b and a transparent film 4b alternately like a belt is extended between the rollers 5, 6. The roller 6 is coupled with a driving motor 7 and the roller 5 is pressed in a direction applying tensile force to the belt-like sheet through an exciting means. When an operator sets up an original on an original platen to use the copying machine, the original adhered by the transparent film 4a can be observed through a window part 1a and the transparent films 4b, 4a, so that the arranging state of distorted original or the like can be corrected. |
