PURPOSE:To position an original so that a specific part is copied on a copying form of prescribed size accurately by receiving original scanning light and projecting original contents upon a copying machine body when a command for confirming the position of the original is outputted. CONSTITUTION:A signal for turning on a mirror displacement key 5 on a console 6 is inputted to a control part 22 after the original 1 is mounted on a platen 2 to drive an actuator 17 through an actuator driving circuit 24. Consequently, a mirror 9d energized by a spring 26 is fallen down by a projecting plunger 17a. Then, a light source lamp 9a is turned on to guide reflected light from the original 1 to behind the displacement mirror 9d. The reflected light is reflected upon a mirror 9e dedicated to the confirmation of the original position to project the contents of the original 1 on a slit 7 for the confirmation of the origginal position provided to tue upper part of the copying machine 8. When a start button is pressed after the specific part is positioned, the displacement mirror 9d returns and normal copying operation is performed. |
