Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of reading resolution and to reduce density irregularities of images by moving the position of an illuminator corresponding to the detected height data of an original on an original platen. SOLUTION: By moving a reflection shade unit 19 vertically or as a fan in conformity to the height of an original surface on an original platen 1, despite the height of the original surface, the distribution of illuminance on the original platen 1 is kept constant.
