摘要： A scanning device reads image data, stores the image data in a unit of raster in a buffer and transferring the image data to a host computer. The scanning device has a stop unit to temporarily stop reading the image data when an empty capacity of the buffer becomes smaller than a predetermined amount, a write unit to write specified mark data in a next storage line of raster image data lastly read and stored in the buffer in response to a temporary stop, and a restart unit to restart reading the image data by overlapping the raster image data lastly read when the empty capacity of the buffer becomes larger than the predetermined amount.
