Note that the same reference numerals in each figure indicate the same or corresponding parts.

Claims

[Claims for Utility Model Registration] Initial reading of the written content of the original by moving back and forth parallel to the reading surface of the placed original and converting the intensity of light from each part of the reading surface into electrical signals. For specifying multiple image densities in an image reader having an image scanner that returns to a position and an image processing unit that processes data from the image scanner to match the image output device connected to the image scanner, It is equipped with a resolution table and an image density converter that converts the image density of input image data based on instructions from the resolution table, and reads the same written content of the above-mentioned document in each of the forward and backward movements of the image scanner. The image data read in is converted to an image density of 1 specified in the resolution table above, and the image data read in the return trip is converted to another image density of 1 specified in the resolution table above. An image reader characterized by transmitting data to an image processing section.
