Abstract
A method and apparatus for scanning an object such as a photosensitive material by using the light beam or beams for use in a picture reproducing machine such as laser reproducing apparatus for plate making are disclosed. An object mounted to a surface of an object holder having a cylinder-like curvature is scanned by a light beam which is incident to a rotary mirror arranged on a rotating axis parallel with the holder's central axis, from the direction perpendicular thereto, and is reflected by the rotary mirror onto the object in the directions of holder's curvature and holder's central axis by rotating the rotary mirror around the rotating axis and moving the light beam in the direction of the rotating axis of the rotary mirror by using a light beam head in relation to the holder.
