摘 要：
Parallel laser beams #1, #2 and #3
produced by splitting one laser beam into three, are introduced to an optical
scanning device (2) along the central axis of a recording cylinder (24), the optical scanning device being disposed on the central axis of the recording cylinder and rotated thereabout, having an inclined mirror surface (4), the recording cylinder holding a recording sheet (S) on an interior surface thereof. The laser beam #2 incident upon the mirror surface at its center of rotation is reflected at the point of incidence, while the laser beams #1 and #3 are deflected by acousto-optical devices (10X, 14X) back and forth in the opposite directions in synchronism with the rotation of the optical scanning device, in parallel planes held at a
distance and including the laser beams #1 and #3 therein, thereby to give the laser beams #1 and #3 angles of incidence upon the mirror surface

摘 要 附 图：
necessary in order for the laser beams #1, #2 and #3 after reflected to produce scanned loci running parallel to each other at a given interval on the recording sheet, regardless of rotational positions of the optical scanning device. To adjust a relative difference in the lengths of the scanned loci, timing at which the laser beams #1, #2 and #3 are turned on/off is controlled. When the laser beams #1 and #3 are deflected so as to gyrate along a conical plane whose central axis is that of the recording cylinder, the laser beams #1, #2 and #3 produce scanned loci
always running parallel to each other at a given interval with the same scanning lengths on the recording sheet. <MATH> 主权项：
