Filed: 2000-09-11
Abstract: PROBLEM TO BE SOLVED: To solve the problem that, when two one-dimensional CCD image sensors are provided at different positions and reflected light from an original is made incident to the sensors by splitting the light into two split reflected light beams through a half mirror, precise alignment becomes difficult and the light quantities of the split reflected light beams decrease in inverse portion to the number of the split light beams and, consequently, the reading out of signal charges with a sufficiently high S/N becomes difficult. SOLUTION: At the time of setting the moving speed of the one-dimensional image sensors, each has N light receiving pixel rows (N>=2) arranged in parallel with each other with intervals equal to D-line spaces in a subscanning direction. In the subscaning direction to a speed which is M times as fast as a normal speed, the D-line intervals between the N light receiving pixel rows are set to meet the relation of D=M.a/n (wherein, n is an integer of <=N and a is an integer when n=N or it not the integer when n<N). For example, when the moving speed of a one-dimensional image sensor 10 having two light receiving pixel rows 11 and 12 is doubled, the interval D between the rows 11 and 12 is set to a 5-line space.
