An image reading apparatus includes a stacking unit, a conveyance unit to convey stacked sheets, a reading unit, a white reference plate provided in a second position, and a processor. The reading unit is movable and, at a first position, reads a conveyed sheet image to obtain image data and, at the second position, reads the white reference plate. The processor generates, based on a plate reading result, a shading correction value and corrects the image data using the shading correction value. Based on whether the number of times in which reading the white reference plate has been performed is less than a predetermined number of times, the reading unit changes a time interval in a reading period that is from a first timing to a second timing. The processor generates, each time the white reference plate is read, the shading correction value based on the plate reading results.

An image forming apparatus includes a sheet feeding tray, a sheet discharge tray, and a conveyance mechanism. The conveyance mechanism includes a guide part, a first turning shaft, a second turning shaft, a coupling member and a drive part. The guide part has a sheet discharge port. The first turning shaft supports the guide part so as to be turned around an axis along a width direction crossing to the conveyance direction. The second turning shaft is provided on the downstream side of the first turning shaft and below the guide part. The coupling member has one end portion supported by the second turning shaft in a turnable manner and the other end portion provided so as to be slidable with respect to the guide part. The drive part turns the coupling member around the second turning shaft to change a height of the sheet discharge port.

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.

In a case in which a carrier sheet including transparent sheet portions of two pieces which can interpose a document therebetween, and a bonding portion which bonds sheet portions to each other is transported in a state in which the bonding portion is located on the downstream side in the transport direction, a reading unit is caused to start reading, after an upstream end of the bonding portion passed through the reading unit.

A display device includes a display portion, a display processing portion, a detection processing portion, and a replacement processing portion. The display processing portion displays a plurality of pieces of character information as a list in a display area set in the display portion. The detection processing portion detects specific character information from among the plurality of pieces of character information displayed by the display processing portion, the specific character information being character information whose display size exceeds a size of the display area. The replacement processing portion, when the detection processing portion detects the specific character information, replaces each instance of a specific word among words included in the plurality of pieces of character information displayed by the display processing portion, with an abbreviation of the specific word, the specific word being a word included in the specific character information detected by the detection processing portion.

An image processing apparatus 1 obtains displacement amounts of patterns formed on front and back sides of a recording sheet respectively, and performs correction of an image formation position based on the displacement amounts. The image processing apparatus 1 calculates the lengths of the sides of each of the front and back sides of a recording sheet by detecting the intersection points of the surrounding edges of the recording sheet with reference to the image data of the each of the front and back sides. A magnification error is calculated based on the lengths of the sides corresponding between the front and back sides. A correction amount is then calculated based on the calculated magnification error in order to make the lengths of each side match each other. Displacement amounts of the positions of the patterns is obtained after correction based on the correction amount.

An image reading apparatus includes a reading device having an opening in an upper surface thereof, a main device disposed below the reading device, a first cable connected to the reading device and the main device and including a first portion, a retaining portion disposed in the main device, and a groove portion. The retaining portion is configured to retain the first portion of the first cable such that the first portion has a substantially U-shaped curve, which is curved downwardly, and such that a liquid passes through the opening of the reading device, runs on the first portion downwardly and drops down from a lower end of the substantially U-shaped curve in the first portion of the first cable. The groove portion is configured to receive the liquid dropping down from the lower end of the substantially U-shaped curve in the first portion of the first cable.

A document management facility may process volumes of physical documents for digital imaging. The document management facility may utilize robotic apparatus to perform the various functions for processing the documents, which may include document intake, document storage, document digitization, and/or document removal. Digital versions of the documents may be accessed with a document management system.

An authentication control apparatus includes a first authenticating unit, a second authenticating unit, a controller, and an outputting unit. The first authenticating unit performs first authentication using authentication information stored in association with a memory area. The second authenticating unit performs second authentication using authentication information stored in association with a user. The controller performs control to perform one of authentication operations that are the first authentication and the second authentication when the user uses the memory area. The outputting unit outputs information if the one of the authentication operations performed under the control of the controller does not succeed. The information prompts the user to input authentication information to be used in an authentication operation performed when the user uses the memory area.

An image reading apparatus includes a line sensor configured to read an image of a target object. The line sensor includes light receiving element arrays arranged at given intervals in a second direction perpendicular to a first direction for a plurality of lines, the plurality of light receiving element arrays each including a first light receiving element configured to receive light of a first color and a second light receiving element configured to receive light of a second color different from the first color, which are arranged in the first direction to form one line. The image reading apparatus is configured to derive a shading correction coefficient for shading correction based on output from the light receiving element arrays that have read a reference white plate, and to identify, as an abnormal pixel, a pixel obtained by reading a foreign matter existing on the reference white plate.
