PROBLEM TO BE SOLVED: To ensure the smooth joining of images to improve the image quality at present, where the higher resolution and deeper reading density are required and also the start-stop frequency increases due to the increase in the quantity of data to be read, in contrast to the conventional image scanner where the image read start timing is not completely synchronized with the exciting timing of a motor that moves the reading position to cause a timing error equivalent to a single line of reading resolution in a start mode after a stop mode, and accordingly the data are read with redundancy/omission that is smaller than the quantity equivalent to a single line of resolution, which defective reading result, however, could be disregarded for the resolution and reading density of the conventional image scanner device. SOLUTION: A means is prepared to secure the same time difference between the image reading start timing and the exciting timing of a stepping motor that moves the reading position before the image reading is discontinued and when the image reading is restarted. Thus, the start-stop image error can be eliminated.
