A small-sized flatbed scanning type image reading apparatus for reading a wide-range image at high resolution is provided. An optical reading system (LU) is movable also in a main scanning direction (X) for high-resolution wide-range image reading. The optical reading system (LU) scans the image with the width of a section (SS,) to be read of elongated rectangular configuration in a subscanning direction (Y), and then is shifted in the main scanning direction to scan the image with the width of the next section (SS,) to be read. The remaining section (SS,) to be read is similarly scanned. The images of these three sections are combined together in consideration for the influences of overlap parts (OL,, OL,) of the sections.

Method of and apparatus for reading image by flatbed scanning

An original holder of the present invention can be inserted in a plurality of different directions into a flat bed scanning-type image reading apparatus. This structure allows both a laterally long image and a vertically long image to be promptly displayed as an erecting image without any specific operations. An original holder (10) embodying the invention includes a lower frame (12) and an upper frame (14), which are joined with each other to allow free opening and closing. The lower frame (12) and the upper frame (14) respectively have inner openings (12W,14W). The original holder (10) holds an original P in such a manner that the periphery of the original P is clamped between the lower frame (12) and the upper frame (14) and that the original P is observable through the openings (12W,14W). The original holder 10 has a substantially square shape. Two guide grooves (16,18) are formed along perpendicular sides on a rear face of the lower frame (12) of the original holder (10), so as to restrict the insertion of the original holder (10) to two directions.
