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.

摘要： A sheet feeding device includes a feeding unit that feeds a sheet; a rolling member that rolls by having contact with the sheet being fed by the feeding unit; a supporting member that moves along with a behavior of the sheet with supporting the rolling member so that the rolling member rolls in a feeding direction of the sheet at a predetermined position on the sheet; an acceleration measuring unit that measures accelerations acting on the supporting member in three directions; and a detecting unit that detects a feed error of the sheet based on the accelerations measured by the acceleration measuring unit.
