  • Patent number: 11209764
    Abstract: An image forming apparatus includes a paper tray, an elevating plate, a cam, and a shutter. The paper tray is configured to hold sheets. The elevating plate on the paper tray is arranged to ascend and descend between a descended position and an ascended position higher than the descended position. The cam is movable between a first position and a second position. The shutter includes a shielding portion. The shielding portion is located at a shielding position when the cam moves to the first position. The shielding position is a position that overlaps with a region in a height direction occupied by the cam at the second position. The shielding portion retracts from the shielding position when the cam has moved from the first position to the second position.

  • Patent number: 10237430
    Abstract: Provided are an image forming apparatus including multiple feed trays and a non-transitory recording medium. One or more hardware processors of the image forming apparatus determine, for each print product to be printed, whether the amount of sheets contained at the beginning of printing the each print product in a feed tray being used for printing, is not less than the necessary amount of sheets for printing the each print product, and cause a print engine to print the print products. In printing the print products, the one or more hardware processors, when determining that the amount of sheets in the feed tray being used for printing, determined for a next print product, which is to be printed next to a print product currently being printed, is less than the necessary amount of sheets for the next print product, cause the print engine to suspend printing the next print product.

  • Publication number: 20140001697
    Abstract: 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.

  • Patent number: 8616543
    Abstract: A guide device includes a plate on which a first medium is to be placed, and provided above a space in which a container is to be inserted, a moving member that moves along a surface of the plate in a supply direction of the first medium or in an opposite direction, a substantially sheetlike guide member that guides the first medium in the supply direction, and a drawing member that draws the moving member toward the plate. When the container is taken out of the space, the moving member is drawn toward the plate in the opposite direction by the drawing member, and the guide member withdraws to a position superposed on the plate. When the container is inserted in the space, the moving member is pushed in the supply direction by the container, and the guide member protrudes from the position in the supply direction.
