摘要： PROBLEM TO BE SOLVED: To make an image formation apparatus compact by efficiently arranging each part which constitutes a solid scanning-type optical writing device. SOLUTION: In the optical writing device 1 (1b and 1c), a driving circuit substrate 120 is formed independently of a head part substrate 112 where an LED 113 as a driving object is mounted, and the driving circuit substrate 120 and the head part substrate 112 are electrically connected to each other via flexible cables 125 and 126. The driving circuit substrate 120 is arranged so that its substrate face is nearly parallel to a perpendicular line which passes the rotation center of a photoreceptor drum 3. The driving circuit substrate 120 becomes nearly perpendicular between adjacent developing units 2c and 2d, and also becomes nearly parallel to outer walls 21 and 22 of the optical writing device 1 side of a developing unit 2. An angle θ' between the driving circuit substrate 120 and an optical axis of an image light of a writing head 110 nearly agrees with an angle θ between the optical axis of the image light of the writing head 110 and the vertical line which passes the rotation center of the photoreceptor drum 3.

摘要： PROBLEM TO BE SOLVED: To provide an image read-out device which can prevent a decline in read-out quality of an original by synthesizing signals of a plurality of photoelectric converters with no time lag and thereby doubling electric charges which will become read-out signals when the sub-scanning speed is increased in reading out the original at a low resolution.
SOLUTION: The image read-out device includes: CCD pairs 8a, each having two lines of photo diode series for reading out an original; a motor driving circuit 14 for sub-scanning the original; and adders 9a, each of which superimposes and synthesizes two outputs from the corresponding CCD pair 8a with a predetermined time lag. When a control portion 11 receives an instruction to read out at a low resolution equivalent to a half of a high resolution from a resolution switch 12a, it controls in such a manner that the two outputs from the CCD pair 8a may be added by the adder 9a with no time lag to double the sub-scanning speed by the motor driving circuit 14.
