摘要： A printer includes a fixing device that fixes a toner image formed on a sheet and a sheet delivery roller pair for delivering the sheet on which the toner image is fixed by the fixing device onto a sheet delivery tray placed outside of a printer main body. The printer includes a supporting member that supports an upstream edge portion of the sheet in a delivery direction delivered from the sheet delivery roller pair so that the upstream edge portion does not fall down on the sheet delivery tray. The printer includes a blower unit that blows air along a lower surface of the sheet supported by the supporting member from the upstream edge portion of the sheet in the delivery direction toward a downstream edge portion of the sheet in the delivery direction.

摘要： A sheet feeding apparatus includes a middle plate, a lifter mechanism, and a sheet-feed roller. The sheet-feed roller can move to a first position retracted from the sheet, a second position lower than the first position for feeding the sheet, and a third position lower than the second position. The sheet feeding apparatus has a position control mode in which when a sheet is fed, the sheet-feed roller is moved from the first position to the third position and stopped there, the middle plate is moved toward the sheet-feed roller by the lifter mechanism, the sheet stacked on the middle plate is brought into abutment against the sheet-feed roller, the middle plate is moved until a position detection sensor outputs the detection signal that the sheet-feed roller is in the second position, and a height of the sheet is controlled.

摘要： Disclosed is a sheet feeder in which sheets are fed by a feeding member from a tray on which the sheets have been loaded. When the tray is driven by a drive unit to lift up the tray from a sheet replenishment position to a position at which sheets can be fed, a first sensor senses that the top sheet on the tray is situated at a prescribed position. Response to this sensing of the first sensor the drive unit performs a predetermined intermittent driving for lifting the tray. It is determined based upon outputs from the first and second sensors whether or not a sheet is present on the tray.
