Abstract

PURPOSE: To design in a small size and enable accurate and smooth forward and backward movements of reflecting merrors, by providing a means to change the focal length of optical means to project to the screen and print section and a driving means.
CONSTITUTION: A screen first mirror 30, a print second mirror 34, and a converter 24 are independently interlocked and movable. When these three parts are in the solid line position K shown in the drawing, the light from an image pickup lens 23 passes through the converter 24 to reach the back face of a screen 32 from the mirror 30 through a second mirror 31, and a magnified view of the image can be monitored on the screen 32. That is, the function as reader is accomplished. At this time, the focal length of the lens 23 is shortened by the converter 24, and the image is imaged on the screen 32 at a smaller magnification as compared with the magnification of the image imaged on the drum 111 in the absence of the converter 24. The mirrors 30, 34 are driven in rotation by driving means, and are allowed to make forward and backward movements in the optical path of the projection lens 23.
