An optical scanning device which divides an area to be scanned on a surface to be scanned into n partial scanning portions in a longitudinal direction thereof. The blade supports have flat mounting surfaces which extend in the machine and cross machine directions and which overlie or underlie the blades supports. A cutting unit cuts a card face image by setting a trimming frame having a predetermined standard size in the normalized face image, with reference to the distance between the positions of the eye centers in the normalized face image. In some cases it is desirable to have a certain number of endpoints controlled by one processor, and other endpoints controlled by a different processor, thus providing a shared control of all the endpoints.
