Abstract
A drive control mechanism for a scanning head which travels along a scan surface and carries out image reading or image writing. The drive control mechanism includes a driving starting position changing device which changes a driving starting position of the scanning head either outside an image reading range or outside an image writing range, under a predetermined condition. Accordingly, phases of vibration periods are shifted and unevenness in density is less visible.
