Abstract

PURPOSE: To achieve the simplification and miniaturization of constitution and achieve the improvement in the accuracy of measurment by installing a solid-state image sensing element array at the end part of a latent image recording drum.
CONSTITUTION: A solid-state image sensing element array A comprising arraying multiple solid-state image sensing elements a composed of photo diodes and charge coupled elements at a minute pitch in one row is so disposed at the end part of the recording drum that the arraying direction of the solid-state image sensing elements a face the deviation measuring direction of a scanning light beam 6. If with this arrangement the scanning light beam 6 from a laser 1 is scanned up to the position 6' by rotating a polyhedral rotary mirror 3, the scanning light beam 6 is radiated by way of a cylindrical lens 1 to a part of the elements a of the solid-state image sensing element array A and by detecting the radiation position thereof, the deviation direction and deviation amount of the scanning light beam 6 by the inclination of the reflecting surface 3m are accurately measured in real time.
