Abstract: An inkjet printer includes a housing that defines a receiving formation for a media tray assembly. A chassis is positioned in the housing. A media tray assembly is displaceably engageable with the chassis to permit the tray assembly to be received in, and withdrawn from, the receiving formation. The media tray assembly and the housing define a print medium feed path. The media tray assembly includes a media tray in which a stack of print medium sheets can be stored. A feed mechanism is positioned on the media tray to feed the sheets from the tray. A printhead assembly is positioned downstream of the media tray to carry out a printing operation on the sheets as the sheets are fed from the tray.

Abstract: A printer prints on two sides of a sheet of paper having continuous pages, and discharges the paper to a postprocessor for disconnecting the paper in page units and storing the disconnected sheets of paper in a stack. Depending on whether the postprocessor has an inversion mechanism that inverts front and back sides of the paper, sides of the paper on which data for the front side of the paper and data for the back side of the paper are printed are switched. With this arrangement, even when the postprocessor does not have the inversion mechanism, the front side data is printed on the back side, and the back side data is printed on the front side thereby enabling the postprocessor to stack the disconnected sheets of paper in page units in the order of page numbers.

Abstract: A portable stamp includes a housing with an elongated slot and a tongue. A handle is movably mounted in the housing. A character unit is pivotally mounted at a distal end of the handle with a first torsion spring. An ink pad is pivotally mounted beneath the character unit with a second torsion spring and abuts a character plate of the character unit. A control unit is movably mounted in the elongated slot and stably mounted in the handle. A cover is detachably mounted at an open end of the housing. When the control unit is pushed towards the open end of the housing, the character unit and ink pad will be respectively pivoted under the forces of the torsion springs to positions perpendicular to the handle for stamping the character plate. Whereby, the stamp is easy to be operated and will not dirty the user's hands.

Abstract: A sheet re-feeding path (32) is disposed substantially horizontally at a location below a fixing unit (14) and an image forming unit. At a location below the sheet re-feeding path (32), sheet decks (3, 4) are disposed horizontally along a sheet conveying direction in the sheet re-feeding path (32). Also, a drawing path (37) for switchbacking the sheet is disposed substantially horizontally between the sheet re-feeding path (32) and the sheet decks (3, 4). A sheet feeding path (7) for feeding the sheet from the sheet deck (3) disposed at an upstream side crosses the drawing path (37) to join to the sheet re-feeding path (32). Accordingly, a space, which is occupied by component parts or devices related to the conveyance of the sheet, can be made compact, whereby sheet capacity can be increased.
