Abstract: The image reading method and the apparatus therefor of the present invention are characterized in that deviation in the optical axis due to changes in the magnification in the auxiliary scanning and main scanning directions are corrected by determining the optimal position of the slit. This allows the resultant images to be very clear-cut without blurs. Further, the slit positioning apparatus of the present invention is characterized in that the slit is positioned so that linear image light by the slit enters a suitable position of a linear sensor. This also allows the resultant images to be very clear-cut without blurs.

Abstract: To provide a scanning head (10) suitable for scanning large-size documents, a plurality of contact type CCDs (12, 14, 16) are staggered on a common substrate (18) with overlapping end portions, so that their sensitive ranges (22, 24, 26) are adjoined to one another. The adjacent ends of two CCDs (12, 14) are fixed on the substrate by stops (28, 34), and the opposite ends of these CCDs are elastically supported to allow for thermal expansion or contraction. Between the first CCD (12) and the third CCD (16), a spacer (40) is interposed which has a thermal expansion coefficient comparable to that of the CCDs, so that the sensitive ranges (24, 26) of the second and third CCDs (14, 16) are matched to one another, irrespective of the expansion or contraction of the second CCD (14).
