Abstract

PURPOSE:To prevent erroneous copying by confirming that an original is placed at a prescribed position on an original placing plate prior to the formation of a picture, by image-forming and displaying the original picture on an external monitor through operating an optical system. CONSTITUTION:An optical system is provided with the 5th mirror 8 which is put on an optical axis only when an original is to be positioned, so light passed through the 1st mirror 3, 2nd mirror and a lens 5 is reflected by the 5th mirror 8 and further reflected by the 6th fixed mirror 9 to be imaged on a monitor 10. Therefore, a user corrects the position of the original if necessary while having a lock at the monitor 10.
