PURPOSE: To cut off light reaching a projection screen during continuous printing operation by providing a means which holds a changeover mirror outside a printing optical system when multiple printing operation.
CONSTITUTION: When continuous copying operation is performed, a scanning mirror 17 moves as shown by an arrow A and a roller 21 atop a projection arm 19 pushes up a lever 22. A movable reflecting mirror 12 rotates around a support shaft 16 as a fulcrum by the movement of a guide roller 25 atop an arm 26 along a guide rail 18 and the tip of the movable reflecting mirror 12 pushed up an arm 28, which is locked. At this time, a solenoid 31 is off. In this state, the movable reflecting mirror 12 is at a position where an optical path to a reader is cut off as shown by a broken line.
