Claims

[Claim for Utility Model Registration] A built-in one-dimensional image sensor performs main scanning of the document surface in the primary direction, and a traveling roller provided at the side edge adjacent to the document reading area is brought into contact with the document surface. In a hand scan device that performs sub-scanning by manually moving the device itself in a secondary direction perpendicular to the primary direction to read image information on a document surface, the roller is formed of a transparent material, and the roller is made of a transparent material. A black and white pattern at equal intervals is formed on the outer peripheral surface of the roller, and a synchronization signal in the sub-scanning direction is detected by reading the black and white pattern on the outer peripheral surface of the roller in a portion of the one-dimensional image sensor that is not used for reading the document. A hand scan device featuring:
