摘要： PROBLEM TO BE SOLVED: To avoid the problem of vibrations without making the width of machine body large and to dispense with complicated arithmetic processing by performing magnification in the sub-scanning direction in the image reading of an image forming device, while using both a method for performing the magnification while changing the conventional moving speed of a carriage and a method for performing magnification through signal processing. SOLUTION: When a scale is smaller than a certain reduction factor at the time of reduction, the carriage moving speed is made about two times the setting factor. A line memory for one main scan line is provided inside an ASIC (1) 704 for a scanner, data for the first one line are stored, and at the time point when the next main scan line is fetched, after the averaging processing with the data of the first line is performed, they are outputted to an image processing ASIC (2) 705 on the following stage. In addition, filtering processing, gradation processing, binarizing, and main scanning direction magnification changing processing at the image processing ASIC (2) 705 on the following stage are performed as usual. The data processed by this image processing ASIC (2) 705 on the following stage are temporarily stored in a page memory(PM) 706.
