Abstract
PURPOSE: To simplify constitution by passing the transmitted light of film through a movable mirror to make its optical path changeable and enables the same to be magnified and projected on a screen through the other mirror.
CONSTITUTION: In the case of ordinary projecting, a movable mirror 6 is in the solide line position and therefore the light transmitted through a film 4 passes through a projecting lens 5 and is reflected by the mirror 6, the reflected light whereof is led to a screen 9. In the case of magnified projection, the movable mirror 6 is moved to the position of alternate long and two short dashes lines and the light transmitted through the film 4 is reflected by the mirror 6 and is then led via other mirrors 7, 8 to the screen 9, where the magnified images are projected. In this case, focus adjustment is accomplished by adjusting the position of the projecting lens 5.
