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 medium-discharging device includes: a discharging section that discharges a medium; a stacker that is configured to stack the medium on a mounting surface and, in a closed state, has the mounting surface facing the housing section; and a first stopper and a second stopper that are configured to switch between a regulating state in which the stopper is in contact with a leading end of the medium and a stored state in which the stopper is stored in the stacker, in which the second stopper is provided at a position which is between the discharging section and the first stopper and at which the second stopper faces the recess when the stacker is in the closed state, and at least a portion of the second stopper enters the recess when the second stopper is in the stored state and when the stacker is in the closed state.

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to raise and lower the sheet placement table to a target position that is determined in accordance with a size of the sheet on the sheet discharge table.

The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to lower the sheet placement table when a human detection sensor configured to detect a human in a detection region has detected a human in the detection region.

An image scanning apparatus includes an image sensor to scan a manuscript, a transfer apparatus to pick up the manuscript and move the manuscript to a manuscript transfer path, and a loading apparatus to load the manuscript scanned by the image sensor. The loading apparatus includes a discharge tray to hold a discharged manuscript and a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript.

An image forming apparatus includes an apparatus body including a housing cover, a printer, a discharge roller, a discharge portion, a scanner, and a document cover. The discharge portion is recessed downward in a vertical direction relative to an upper surface of the housing cover and includes a first wall and a second wall, and a receiving surface situated therebetween. The scanner is disposed downstream from the discharge portion in a sheet discharge direction, and includes a document table and an image sensor. The document cover is configured to pivot between a first position at which the document cover covers the document table of the scanner from above and a second position that is different from the first position. When the document cover is located at the first position, an upper surface of the document cover is substantially level with a downstream end of the receiving surface.

An image forming apparatus can create various output products using a transparent sheet as intended by a user.

A scanner includes a lower unit and an upper unit. The lower unit includes a first document table on which a first document is to be placed. The upper unit includes a second document table on which a second document is to be loaded and a document feed path through which the second document is to be picked up from the second document table fed, the upper unit being coupled to the lower unit to pivot between a closed position in which the first document table is covered and an open position in which the first document table is exposed. The upper unit further includes a reading unit to read an image from the first document and the second document by performing flatbed scanning on the first document and document feed scanning on the second document.

An image-forming apparatus includes, in a body having a predetermined house, an image-reading unit and an image-forming unit that is configured to form an image read by the image-reading unit. A discharge portion is configured to discharge a sheet on which the image was formed onto a discharge tray. An intra-apparatus-discharge space is formed in the body between the image-reading unit and the image-forming unit. The housing includes therein a consumption article mounting portion in which a consumption article used by the image-forming unit is mounted. At least a portion of a surface of the housing at a region of the consumption article mounting portion has a light-transmissive property. When the consumption article is consumed and needs to be replenished, the operator can visually check the region of the consumption article mounting portion in the housing from the outside of the body through the transparent portion.

Disclosed is a belt transfer type multi-function device for printing an image transferred on a belt to paper moving between a transfer roller and a belt roller, including a control device performing controlling such that an image to be printed on paper already caught between the transfer roller and the belt roller is printed as it is, and if printing should not be performed on next paper along a movement direction of paper, movement of the next paper is stopped on a transfer path of paper before the next paper is positioned between the transfer roller and the belt roller, the image already transferred on the transfer belt is deleted in a state in which the next paper is maintained to be stopped on the transfer path of paper, and the next paper in a stopped state is ejected as a blank paper through a ejection port of printed paper along the transfer path of paper, so that the image already transferred to the transfer belt, which is to be printed on the next paper along the movement direction of paper, is not printed on the next paper.
