Claims

[Scope of Claim for Utility Model Registration] (1) An image reading means in which a plurality of light-receiving elements are provided in a line and reads both information on the document by photoelectrically converting light reflected from the document; A reference jig whose edge is painted black and set at the original set position, the point where the edge changes from black to white becomes the reading start position, and data read from the reference jig by the image reading means when inputting correction data. and a correction means for storing correction data from the image reading means and outputting only the data after the reading start position among the data read from the original by the image reading means as regular data based on the correction data when reading the original. An image reading device characterized by: (2) The correction means has a memory that stores the number of bits from the point of change from black to white at the edge of the reference jig as correction data when correction data is input, and when reading the original, the correction means stores the number of bits from the image reading means when reading the document. The image reading device according to claim 1, wherein the image reading device outputs data after the specified number of bits as regular data.
