ABSTRACT:
An image of a microfilm is projected on a screen by light emitted from a light source. A pair of cursors are provided on each of adjacent sides of the screen so that a desired area of the image displayed on the screen can be designated by moving the cursors. A rotary mirror for scanning the image of the microfilm is arranged between the microfilm and the screen. The image of the microfilm is guided to a photosensitive drum by the mirror. A shutter is located between the photosensitive drum and the mirror. By controlling the shutter and the light source in accordance with an area designated by the cursors, an image of the microfilm corresponding to the designated area can be formed on the photosensitive drum.
