Claims

[Scope of utility model registration request]

A two-dimensional image sensor comprising a one-dimensional image sensor in which a plurality of image reading sensors are arranged in a straight line, and a scanning mechanism that performs sub-scanning with a lamp and a mirror in a direction perpendicular to the sensor arrangement direction of the image sensor. In an image reading device that reads image data, a reading pattern having a reference length in the sub-scanning direction is provided on the reading side surface of a frame of a document table, and a measuring means for measuring the reading time of the pattern to be read; an image reading apparatus comprising: a correction means for correcting the reading density in the sub-scanning direction according to the time of the image reading apparatus.
