Image processors are provided for respective groups formed by grouping of images, the order of which is sequential when images respectively having overlapping portions corresponding to the same portion of an object are arranged so as to be adjacent to each other, and concurrently perform processing to detect combining-position information for combining an image in a group and an image adjacent to the image without any positional displacement by image-matching. The combining-position information between images belonging to different groups is respectively transferred, via combination-information transferring paths, between the image processors and between the image processors.

A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.

A reading device and an image forming apparatus. The reading device includes a reader disposed at a scanning position, the reader being configured to read an image formed on a surface of a sheet, a movement mechanism to move the reader between the scanning position and a separated position away from the scanning position, and a reference plate disposed at a first position facing a reading face of the reader, the reference plate being configured to obtain a reference value to be used when the reader reads the image. In the reading device, the reference plate rotates around an axis from a second position facing a side of the reader to the first position or from the first position to the second position in conjunction with movement of the reader from the scanning position to the separated position by the movement mechanism The image forming apparatus includes the reading device.

A reading device includes a base on which a read target object is placed, a reader that reads the read target object placed on the base, a first attachment frame to which the reader is attached such that the reader is disposed above the base, an operation unit that is used for operating the reading device by touching, a second attachment frame to which the operation unit is attached such that the operation unit is disposed above the base, and a support frame that has a first surface and a second surface more bendable than the first surface in response to an external force. The first attachment frame is fixed to the first surface of the support frame. The second attachment frame is fixed to the second surface of the support frame.

An image reading device includes a housing that includes a transport path along which a document is transported, an opening and closing member that is attached to the housing in such a manner as to be openable and closable, a reading unit that is disposed in such a manner as to be positioned between the transport path and the opening and closing member and that reads an image from the document, which is transported along the transport path, and an opposing member that is disposed in such a manner as to be opposed to the reading unit with the transport path interposed between the opposing member and the reading unit and that is moved away from the reading unit in conjunction with an opening operation of the opening and closing member.

A conveying device can selectively execute discharge processes of a plurality of discharge procedures each having a different mode of discharge to a discharge tray. An image reading portion reads images on document sheets conveyed along a conveyance path and outputs data about read images. An image reading control method includes detecting a target image that satisfies a predetermined sorting condition associated with any one of the plurality of discharge procedures from the read images. The image reading control method further includes, in a case where the target image is detected, executing a discharge control that causes the conveying device to execute the discharge process of the discharge procedure corresponding to the target image.

An image forming apparatus includes a conversion unit configured to convert image data based on a conversion condition, an image forming unit configured to form an image on a sheet based on the converted image data, a detection unit configured to detect a pattern image on a transfer member, a reading unit configured to read a test image formed on a sheet, a controller configured to perform calibration based on a reading result of the reading unit, and a reception unit. In a case where the calibration is performed, the controller determines an image forming condition based on a result of detection by the detection unit before the test image is formed. In a case where the reception unit receives the discontinuation instruction, the controller changes the image forming condition to an image forming condition before the pattern image is formed.

A reading device and an image forming apparatus. The reading device includes a reader disposed at a scanning position, the reader being configured to read an image formed on a surface of a sheet, a movement mechanism to move the reader between the scanning position and a separated position away from the scanning position, and a reference plate disposed at a first position facing a reading face of the reader, the reference plate being configured to obtain a reference value to be used when the reader reads the image. In the reading device, the reference plate rotates around an axis from a second position facing a side of the reader to the first position or from the first position to the second position in conjunction with movement of the reader from the scanning position to the separated position by the movement mechanism The image forming apparatus includes the reading device.

A reading apparatus includes: a reading section that reads a side of a medium; a first medium transport path that includes a position facing the reading section; a second medium transport path coupled to a medium mounting section and coupled to the first medium transport path, the second medium transport path being inclined at a first angle with respect to the first medium transport path; and a third medium transport path coupled to the first medium transport path, the third medium transport path being inclined at a second angle, which is less than the first angle, with respect to the first medium transport path.
