A sheet feed device comprises a first conveyance path and a second conveyance path which are different sheet conveyance paths, and a conveyance path merging section for merging the first conveyance path and the second conveyance path together. At least one of the first conveyance path and the second conveyance path includes an upstream side roller that feeds sheet to downstream side in a conveyance direction. The conveyance path merging section comprises a conveyance roller pair that conveys the sheet fed from the first conveyance path and the second conveyance path through a nip; a variable mechanism that makes an arrangement angle of one roller of the conveyance roller pair to the other roller thereof variable; and a transmission mechanism that transmits a driving force from the upstream side roller provided in one of the first conveyance path and the second conveyance path to the variable mechanism.

A first feeder contacts a first surface of a first sheet held in a first tray and feeds the first sheet toward a recording unit. A second feeder contacts a first surface of a second sheet held in a second tray and feeds the second sheet toward the recording unit. An inner member is disposed above a standing plate. An outer member comprises an upstream portion opposing the standing plate, and a downstream portion opposing the inner member. The inner member guides the first surface of the first sheet and the first surface of the second sheet. The standing plate guides the first surface of the second sheet. The upstream portion of the outer member guides a second surface of the second sheet, and the downstream portion guides a second surface of the first sheet and the second surface of the second sheet. The standing plate moves relative to the outer member.

An image forming apparatus is provided. The image forming apparatus includes a paper-feed unit, a developing unit to form an image in a printing medium, an insertion unit including first and second rollers configured to insert the printing medium conveyed from the paper-feed unit into the developing unit, and a guide unit rotatably disposed about a rotation shaft of the first roller and configured to guide the printing medium moving from the paper-feed unit to the insertion unit and selectively press the first roller to the second roller.

An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.

Provided are a finisher, a non-transitory computer-readable recording medium and a method for controlling transportation of media sheets. The finisher includes a sheet transporter, a sheet cutter for dividing each printed media sheet into multiple cut media sheets by cutting, a sheet inserter that inserts insertion sheets into the sheet path, a sheet stacker for stacking the cut media sheets and the insertion sheets transported by the sheet transporter, a sheet buffer disposed on a branch line branching off from the sheet path, and a controller. The controller sets a sheet insertion mode to a pre-sheet insertion mode or a post-sheet insertion mode, and causes the sheet transporter to transport a part of cut media sheets or an insertion sheet into the sheet buffer and change the order of the sheets in the sheet path so that the insertion sheet is positioned between the cut media sheets.

A printing device includes: a casing; a first accommodating unit accommodating therein a printing medium; an image recording unit; a cutting unit; a supporting unit; a second accommodating unit; a first conveying passage; and a second conveying passage branching from the first conveying passage. The image recording unit is configured to record an image on the printing medium. The cutting unit is configured to divide the printing medium into a first medium and a second medium. The supporting unit is configured to support the printing medium conveyed in a first direction. The printing medium accommodated in the first accommodating unit is conveyed to the supporting unit along the first conveying passage. The second accommodating unit is positioned upstream of the image recording unit in the first direction and configured to accommodate therein the second medium. The second medium is conveyed to the second accommodating unit along the second conveying passage.
