Abstract: PURPOSE: To obtain an easy to see image on a screen by providing a shifting optical system in an optical system projecting the exit light from a modulation element. CONSTITUTION: A writing image seen from the writing light side of a modulation optical element 1 is inclined by 90 degrees to the right. The almost parallel incident light modulated according to the writing light is emitted with the optical system different from that of an incident light and constitutes a projecting optical system.

Moreover, since an optical axis through which the light beam H1 passes is emitted from the mirror 11 almost parallel with the horizontal direction, the image to be projected on the screen is shiftingly projected on the part upper than the horizontal direction. A light beam H12 similarly passes the lens 6 to advance on the minute mirror 8 to be reflected and is retracted at the lens 9 to be reflected at mirrors 10, 11 and then is projected in the center of the upper part of the image on the screen.
