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.

摘要： An apparatus includes imaging units, each including: a light source to emit light; and an image sensor to pick up an image of a medium to be moved relatively between the imaging units. The light source of one of the imaging units is provided at a position where a direct light is guided to the image sensor of the other imaging unit, and the image sensor of the other imaging unit is configured to pick up an image for image formation when a reflected light emitted from the light source of the other imaging unit and reflected by the medium is guided to the image sensor of the other imaging unit, and to pick up an image for edge detection when the direct light is guided to the image sensor of the other imaging unit, and an edge of the medium is detected based on the image for edge detection.
