Abstract
Three linear image sensors (14B, 14G and 14R) read the image of an original (1) being moved along the subscanning direction (-Y), by receiving lights (L.sub.B, L.sub.G and L.sub.R) from respective instantaneous reading lines (W.sub.B, W.sub.G and W.sub.R), respectively. Scanning line switching clocks serving as sensor drive timing signals are supplied from a control circuit (20) to the linear image sensors, respectively. These clocks are time-shifted from each other by the time shift values calculated from deviations between the instantaneous reading positions and scanning line pitch, thereby the linear image sensors read common scanning lines.
