An image forming system includes an image forming apparatus which forms an image on a sheet, an image reading apparatus which reads the image formed on the sheet by the image forming apparatus, and a finisher which performs a post-printing process with the sheet. The image forming system further includes: a paper path which is provided in the image reading apparatus and through which the sheet is passed; and an electricity eliminator which is arranged in the upstream side of the finisher to eliminate static electricity of the sheet, wherein the electricity eliminator applies at least one of water and charge to front and back sides of the sheet.

A medium discharging device includes a discharging unit which discharges a medium; and a medium receiving tray which receives the medium discharged by the discharging unit, and is switched between an extended state and an accommodated state, in which the medium receiving tray is provided with a base tray, a main extending unit that is accommodated or extended, and at least one sub-extending unit that is accommodated or extended, and in which the base tray forms an accommodating space for accommodating at least the one sub-extending unit, and is provided with a first protrusion portion protruding toward the accommodating space.

A document feeder constituting an image forming apparatus includes a paper feeder to supply a document to a document transport path, a first transporter to transport the document toward image reading positions, and a second transporter to transport the document toward the document discharging tray while supplying the document to the image reading positions. Furthermore, the document feeder includes a motor provided on the first frame, a first driver provided on the first frame and to transmit driving force generated by the motor to the paper feeder and the first transporter, a second driver provided on the second frame and to transmit the driving force generated by the motor to the second transporter, and a second driver to transmit the driving force generated by the motor to the second transporter, and a relay transmission member to transmit the driving force generated by the motor to the second driver.

The likelihood of a medium jamming is reduced or avoided during discharging media to a discharged-sheet receiving tray, and a plurality of media are appropriately discharged to, and stacked on, the discharged-sheet receiving tray. A scanner includes an apparatus body including a reading section that reads a sheet, a discharge roller pair that is provided inside the apparatus body and discharges the sheet after reads in the reading section, and a discharged sheet tray that receives the sheet being discharged by the discharge roller pair. The discharged sheet tray includes a first member that has at least a portion that is located inside the apparatus body. The first member is that supports the medium at a position higher than the placement surface of the discharged sheet tray.

An image forming apparatus is provided. The image forming apparatus includes a scanner configured to scan a plurality of manuscripts, at least one processor configured to generate classification information of the plurality of manuscripts using a scanning result of the plurality of manuscripts, and a display configured to display guide information of the plurality of manuscripts for manuscript classification using the generated classification information.

A medium discharging device includes a discharging unit which discharges a medium; and a medium receiving tray which receives the medium discharged by the discharging unit, and is switched between an extended state and an accommodated state, in which the medium receiving tray is provided with a base tray, a main extendeding unit that is accommodated or extended, and at least one sub-extendeding unit that is accommodated or extended, and in which the base tray forms an accommodating space for accommodating at least the one sub-extendeding unit, and is provided with a first protrusion portion protruding toward the accommodating space.

An image reading apparatus includes a shooter where a first mounting surface that is inclined with respect to a horizontal plane is formed thereon, a stacker, a supporting unit that movably supports the stacker in such a manner that the stacker is arranged in a first region or a second region, a conveyance unit that conveys a document from the shooter to the stacker when the stacker is arranged in the first region, and a reading unit that reads an image from the document when the document is conveyed by the conveyance unit, wherein a surface area of a region of the first mounting surface that is covered by the stacker when the stacker is arranged in the first region is greater as compared with that when the stacker is arranged in the second region, and the stacker is formed to be capable of being lengthened or shortened.

An image forming apparatus in which at least part of an image scanner is disposed in an area below an original discharge unit and above an image forming unit.

A printer includes a cassette or tray for storing a sheet to which a wireless tag is attached, a conveyer configured to convey the sheet for printing, a wireless tag reader/writer configured to read and write information from and to the wireless tag when the sheet is conveyed for printing, a scanner, and a controller configured to: control the scanner to read a symbol, determine whether the symbol indicates an identification code that identifies a type of the sheet, upon determining that the symbol indicates the identification code, acquire parameters used for controlling the conveyer or the reader/writer corresponding to the type of the sheet, and control the conveyer and the reader/writer using the parameters when printing is performed on the sheet.

An image reading apparatus includes a document support portion, a cover portion which is capable of opening and closing, a first surface of which forms an apparatus top surface, and a second surface of which forms a support surface which supports the document, and a base frame which forms the apparatus top surface, in which the document support portion is provided to be capable of rotational movement and is capable of switching between a first posture and a second posture, in which the first surface of the cover portion forms the apparatus top surface which runs along a horizontal direction together with a top surface of the base frame in the closed state, and in which, in the first posture, a portion of the document support portion is at a height position running along the second surface of the cover portion in the closed state.
