An image processing device includes first and second feeding units. The first feeding unit feeds a sheet toward the second feeding unit in a sheet feeding direction via a sheet feeding path. The device further includes an image processing portion. The first feeding unit is in the path upstream of the processing portion and includes a first shaft rotating in the feeding direction. The second feeding unit is in the path downstream of the processing portion, and the first and the second units feed and hold the sheet. The second feeding unit includes a second shaft rotating in the feeding direction. The device includes a first supporting member supporting first and second ends of the first shaft, a second supporting member supporting first and second ends of the second shaft, and a third supporting member supporting one shaft at a predetermined portion which is not either end of either shaft.

An image forming apparatus includes an image forming unit, a first reader/writer device, a second reader/writer device, and a control unit. The first reader/writer device executes a wireless read/write operation on a wireless tag and is positioned in a sheet conveying path upstream of the image forming unit. The second reader/writer device executes a wireless read/write operation on a wireless tag and is positioned in the sheet conveying path downstream of the image forming unit. The control unit controls the image forming unit, the first reader/writer device, and the second reader/writer device. The control unit controls the second reader/writer device to perform an operation to detect a defect in a wireless tag that is included in a sheet as the sheet is conveyed along the sheet conveying path past the location of the second reader/writer device.

An image forming apparatus has a scanning apparatus. The scanning apparatus has a control panel to enter operating instructions to the image forming apparatus to scan and store a document or scan, store and shred the document. The scanning apparatus has a feeding mechanism. A scanning mechanism is coupled to the feeding mechanism scanning and storing the document placed within the feeding mechanism. A shredding apparatus is coupled to the scanning apparatus. The shredding apparatus has a housing. A shredding feed mechanism is coupled to the scanning apparatus feeding the document from the scanning apparatus into the shredding apparatus when scan, store and shred is selected on the control panel. A cutting mechanism is in communication with the shredding feed mechanism shredding the document when scan, store and shred is selected on the control panel.

A multi-function apparatus employs an in-body sheet discharge type configuration. The image forming device includes a front door and a multi-purpose tray. The front door is movable between a closed position set along a side surface at one side of a case of the image forming device and an opened position opened at the one side with respect to the side surface. The front door has an opening formed therein. The multi-purpose tray is provided to be selectively located at a non-use state at which the multi-purpose tray closes the opening and an in-use position at which the multi-purpose tray opens the opening. When the front door is located at the closed position and the multi-purpose tray is located at the non-use position, an upper end surface of the multi-purpose tray is exposed upward.

An image reading apparatus including a reading unit comprising a photodetector configured to read an image information on a sheet, and a projecting portion, a case storing the photodetector therein, the case comprising a transparent portion configured to transmit light to be received by the photodetector, and a portion defining an opening through which the projecting portion is projected outward from the case, and an elastic portion provided to fill a space where the projecting portion is not present in the opening. The case movably stores the photodetector within a range where the projecting portion is movable in the opening.

A document conveying apparatus includes a document reversing part, a stacking tray stacking the document, a discharge tray provided under the stacking tray, a lift member provided downstream in a document conveyance direction of the stacking tray and configured to be turnable upward such that a downstream end of the document stacked on the stacking tray comes into contact with a feed roller disposed above the stacking tray, a first document conveyance path defined downstream in the document conveyance direction of the feed roller to the document reading part, a second document conveyance path defined from the document reading part to the discharge tray, and a third document conveyance path defined from a middle of the second document conveyance path through the document reversing part, wherein a bottom surface part of the lift member defines a part of an upper part of the third document conveyance path.

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.

A sheet conveying system includes: an upstream apparatus provided on an upstream side in a conveyance direction of a paper sheet; a downstream apparatus provided on a downstream side of the upstream apparatus; an upstream conveyor that conveys the paper sheet; an upstream driver that drives the upstream conveyor; a downstream conveyor that receives the paper sheet conveyed from the upstream conveyor, and conveys the paper sheet received from the upstream conveyor; a downstream driver that drives the downstream conveyor; an upstream controller that is connected to the upstream and downstream drivers; and a downstream controller that is connected to the downstream and upstream drivers, wherein the sheet conveying system switches control on the basis of sheet information between first control in which the upstream controller controls the upstream and downstream drivers and second control in which the downstream controller controls the downstream and upstream drivers.

Temperature of a printing medium 110 is sufficiently decreased by stopping the printing medium 110 in a discharge path, conveying the printing medium at a low speed, switching a conveyance path, or the like. If the temperature of the printing medium 110 can be sufficiently decreased, the thermochromism phenomenon is suppressed. As a result, it is possible to provide an image forming apparatus capable of achieving highly accurate color matching and color stability.
