Abstract
In an image projecting apparatus such as a microfilm reader and a microfilm reader printer, the inclination angle of a screen surface can be changed without causing distortion and blur in a projected image on the screen surface. The inclination angle of the screen can be changed for the user to see the screen surface with ease such that the screen surface becomes perpendicular to the user's line of sight and the external light reflected by the screen surface is prevented from entering the user's eyes.
