Claims (1)

[Scope of Claim for Utility Model Registration] 1. A document table on which a document to be read is placed; a converging optical system that is placed opposite to the document table and forms an image of the image information on the document table at the same magnification; A one-dimensional solid-state image sensor disposed at the imaging position of the converging optical system, a scanning mechanism that moves the one-dimensional solid-state image sensor in the sub-scanning direction, and a scanning mechanism that moves the one-dimensional solid-state image sensor in the sub-scanning direction on the document table outside the document reading area. a straight line mark for correction written on the mark, a mark discriminating means for discriminating the straight line mark for correction when it is read by the one-dimensional solid-state imaging device, and a mark discriminating means for discriminating the straight line mark for correction when it is read by the one-dimensional solid-state image pickup device; An image information reading device comprising: a correction means for correcting a deviation when reading image information in each main scanning line starting from . 2. The image information reading device according to claim 1, wherein the correction linear mark and the document are read by the same one-dimensional solid-state image sensor. 3. Scope of Utility Model Registration Claim 1, characterized in that the one-dimensional solid-state image sensor is of two types: a solid-state image sensor that exclusively reads correction straight line marks, and a solid-state image sensor that exclusively reads a document reading area.
The image information reading device described in .
