An image reading apparatus includes a reading unit, a conveyance unit configured to convey the sheet, a support portion configured to support the conveyance unit openably and movably with respect to the reading unit in a vertical direction between an upper position and a lower position, a bundled wire transmitting a signal or electric power to the conveyance unit, and a cover portion configured to cover the bundled wire. The cover portion includes a first cover member provided on the conveyance unit and a second cover member provided movably in the vertical direction with respect to the reading unit. A whole length of the cover portion in the vertical direction in a case where the conveyance unit is located at the upper position is longer than a whole length of the cover portion in a case where the conveyance unit is located at the lower position.

An image reading apparatus includes a scanner unit including a first image reading portion configured to read an image of a first surface of a document through a first flow-reading glass, an ADF including a second image reading portion disposed on an opposite side of the first image reading portion across a sheet conveyance path and reading an image of a second surface of the document through a second flow-reading glass. The image reading apparatus further includes a gap forming member disposed on either one of the second flow-reading glass and a moving guide unit and abutting with another one of them. The moving guide unit is provided in the scanner unit and is urged by springs to be movable toward the second flow-reading glass.

Provided is an image reading apparatus, including: a reader comprising a light source upstream of an image reading position and a light source downstream of the image reading position in a moving direction, each light sources sequentially irradiating an original with light of different colors, the reader reading an original image at the image reading position while moving each light sources relatively to the original in the moving direction; a controller controlling the reading of the original image by the reader by setting a light amount ratio of the light source arranged on the upstream side to the light source arranged on the downstream side for a particular color of the different colors to be different from a light amount ratio for another color; and a detector detecting an image pattern of the particular color depending on the light amount ratio from the original image read by the reader.

An image forming apparatus is provided. the apparatus comprises a sheet feeding unit to supply a plurality of types of sheets; an image forming unit to form an image on a sheet; a detection unit to detect an image formed on the sheet; and a controller that causes correction information for each sheet type to be saved in a storage, and under set conditions, causes a specified type of sheet to be supplied by the sheet feeding unit, causes a chart for gradation correction to be formed by the image forming unit, and causes the correction information to be generated based on image information for which the formed chart for gradation correction was detected by the detection unit, and saves the correction information in the storage.

A multifunction apparatus includes a reading mechanism including a document discharge port configured to discharge a document, a recording mechanism including a medium discharge port configured to discharge a recording medium, and a control unit, and a path through which a leading end of the recording medium discharged from the medium discharge port passes and the document discharged from the document discharge port have such a positional relationship to intersect with each other at an intersecting position, and when the leading end of the recording medium is discharged from the medium discharge port in a stop state where the document discharged from the document discharge port blocks the path of the leading end of the recording medium discharged from the medium discharge port, the control unit performs a predetermined operation for canceling the stop state before causing the leading end of the recording medium to reach the intersecting position.

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.

A cover that covers side surfaces of a document conveyance path and a paper feeder in a direction orthogonal to a document conveyance direction and a notifier that notifies information on a document placement section are included. The cover has a first side surface disposed along the document conveyance direction and a second side surface disposed from an end of the first side surface on the paper feeder side toward the document placement section. The notifier includes a displayer that displays the information by light. The displayer includes a first displayer disposed on the first side surface and a second displayer disposed on the second side surface toward the document placement section. The first displayer and the second displayer each have a horizontal length that is longer than a vertical length.

An image reading apparatus includes first and second image reading units, and first and second transparent guides disposed along a conveyance path and guiding a document passing through a conveyance path. The first and second transparent guides are disposed to oppose to each other across the conveyance path. The image reading apparatus also includes a grounding portion provided on one of the first and second transparent guides and a conductive portion electrically connecting the first and second transparent guides with each other.

An image recording apparatus includes a conveyor configured to convey a sheet in a conveying direction, an image recording engine configured to record an image on the sheet, a cutter configured to cut the sheet, a reader configured to read an image on a medium, an operation interface, a display, and a controller. The controller executes reading an image on the medium with the reader, recording an image on the medium which is read in the reading on the sheet with the image recording engine, cutting the sheet at a prescribed position in the conveying direction with the cutter, and displaying a first screen on the display before executing the reading, the recording, and the cutting. The first screen includes a first icon representing the medium to be read with a rectangle and a second icon representing the cut sheets with at least portions of at least two rectangles.

A medium conveying apparatus includes an imaging device to image a medium and configured to move in a moving direction, a roller configured to move in the moving direction, on an upstream side of the imaging device, a conveyance guide provided with the imaging device to move the imaging device, wherein the conveyance guide includes a slope for coming into contact with the medium, an engaging member provided with the imaging device to move the imaging device, and a moving member to move the imaging device by engaging with the engaging member in conjunction with a movement of the roller. The engaging member and the moving member are configured to be separated at a distance from one another when the medium is not conveyed. The moving member moves the imaging device by engaging with the engaging member only when the medium has a thickness greater than the distance.
