A printing apparatus includes a supply unit, a supply path, first and second conveyance paths, a printing unit, and an inversion roller. The first conveyance path conveys, to a first direction, a print medium. The printing unit prints an image on the two surface of the print medium. The inversion roller inverts a conveyance direction of the print medium and conveys the print medium in a second direction. The second conveyance path conveys the print medium conveyed in the second direction to the first conveyance path while inverting the print medium. When performing printing on both sides of print media, the print media are convey such that a first print medium supplied from the second conveyance path and a second print medium supplied from the supply path overlap in the first conveyance path.

This disclosure is directed to a scanning device having a which has a tray set, a movable scanning module and an automatic document feeder. The tray set has a feeding tray and a first output tray. The movable scanning module is movable between a first position and a second position. The automatic document feeder has a flip path, a feeding path, an output path, a returnable path and a feeding wheel group. The feeding path is disposed corresponding to the first position and connecting with the feeding tray and the flip path. The output path is disposed corresponding to the second position and connecting with the first output tray. The returnable path has an intersection connecting with the flip path and the output path. The movable scanning module scans two sides of the sheet at the first position and the second position respectively.

A sheet discharge apparatus includes a stack portion, a reversing unit configured to reverse a reversing sheet, a support member configured to support a lower surface of the reversing sheet, a discharging unit configured to discharge a discharging sheet from the apparatus body, a pivotable member arranged above the stack portion, and a detector configured to output a detection signal that changes according to a pivot angle of the pivotable member. When viewed in a sheet width direction perpendicular to the first conveyance direction, a pivoting locus in which the pivotable member pivots overlaps the support member.

A sheet turning apparatus includes first and second sheet conveyors configured to convey a sheet along respective sheet paths. The sheet is conveyed by the first sheet conveyor in a first disposition relative to an orientation of the first sheet conveyor. Also included is a chamber configured to receive the sheet from the first sheet conveyor. The chamber has an orientation different than the orientation of the first sheet conveyor or an orientation of the second sheet conveyor. The sheet is discharged from the chamber to the second sheet conveyor in a second disposition relative to the orientation of the second sheet conveyor. The second disposition is reversed from the first disposition. Also provided is a method for turning a sheet.
