An image reading apparatus includes a separating roller that is capable of switching between a separation state in which an original document is separated and a non-separation state in which the original document is not separated, and determines whether or not the original document is fed in the separation state or the non-separation state based on the types of the original document set through a user interface for instructing a select of the types of the original document to be read and a start of reading the original document.

An image forming system may comprises an image forming unit, a sensor, and a controller. The controller configured to control the sensor based on measurement modes including a first measurement mode and a second measurement mode. A sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the first measurement mode is less than a sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the second measurement mode.

Systems and methods for contact imaging of stands with illumination are disclosed herein. A contact imaging system can include a contact imager. The contact imager can include a housing having a base and a lid. The lid can have a closed position against the base and an open position. The contact imager can include a contact area image sensor. The lid can shield the contact area image sensor from ambient light when the lid is in the closed position. The contact imager can include an illuminator that can illuminate at least a portion of a blot on the contact area image sensor when the lid is in the closed position.

An image reading device, which is included in an image forming apparatus, includes a first transparent body, a second transparent body, a holding body, and a reading body. The second transparent body is disposed separated from and inclined at a predetermined angle to the first transparent body. The holding body holds the first and second transparent bodies. The reading body moves in a sub-scanning direction along the first and second transparent bodies. The holding body includes a flat face and a frame-shaped face. The flat face is contiguous to the first transparent body on a same plane and smoothly connected with the second transparent body. The frame-shaped face projects outwardly beyond the second transparent body facing the reading body. The reading body moves and contacts the first transparent body and the holding body, and moves with a gap relative to the second transparent body.

An image reading apparatus includes a separating roller that is capable of switching between a separation state in which an original document is separated and a non-separation state in which the original document is not separated, and determines whether or not the original document is fed in the separation state or the non-separation state based on the types of the original document set through a user interface for instructing a select of the types of the original document to be read and a start of reading the original document.

A media scanner including an input tray, an output tray disposed above the input tray, a media feeder to advance media along a media path from the input tray to the output tray, an upper scanning device to generate a first scan line, and a lower scanning assembly. The upper scanning device is disposed to face downward to scan a first side of the media. The lower scanning assembly is disposed to face upward to scan a second side of the media. The media path extends from the input tray to below the upper scanning device, to above the lower scanning assembly, and to the output tray. The upper scanning device is disposed at an angle with respect to the media path to cause a front edge of the media advancing along the media path to contact the upper scanning device at or before the first scan line.

An image reading apparatus includes a conveying unit to convey a document, first and second reading units, a reception unit, a selection unit, and a setting unit. The first reading unit generates image data form a document first side and the second reading unit generates image data from a second side in parallel with the first reading unit reading. The reception unit receives settings regarding a size, an orientation, and a document opening direction of the document. The selection unit selects either a first reading method causing the first and second reading units to read per the set size, and a second reading method causing the first reading unit to read the first side per the set size and causing the second reading unit to read an entire second side. The setting unit sets image data corresponding to the document second side reading by the second reading method.
