Title:
IMAGE PROCESSOR
Document Type and Number:
Japanese Patent JP3460686
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize an image processor by which image information is composited using a simple constitution by using plural exposure heads.
SOLUTION: First to third prisms 211-213 are arranged in order in the vertical direction by keeping specified intervals right on an exposure position 203 at the feeding path of a photosensitive material 201, and first to third exposure heads 215-217 for performing exposure of three colors are arranged so as to correspond to them. Also, an image quality adjustment sensor 204 for detecting a light beam emitted by the exposure heads 215-217 and passing through the prisms 211-213 is arranged under the exposure position 203. The correction of the color slippage of three colors in a subscanning direction is performed by controlling the positions of the prisms 211-213 using control devices 221-223. The image processor is made compact by simplification of an optical system.
