摘要： A feeding tray is detachably mounted on a base member and includes a bottom portion. The bottom portion has a first side that is configured to hold a recording sheet and a second side opposite the first side. An image forming unit forms an image on the recording sheet. A feeding roller is configured to rotatingly contact the recording sheet held in the feeding tray, thereby feeding the recording sheet toward the image forming unit in a conveying direction. A roller arm has one end that rotatably supports the feeding roller and another end opposite the one end. The roller arm is configured to swing about the another end, thereby generating a pressing force for pressing the feeding roller against the recording sheet. A supporting member is provided at the second side of the bottom portion and is configured to support the bottom portion against the pressing force.

摘要： An inclined separating surface includes an upwardly curved surface that is gradually lowered near the ends, from a middle portion in a sheet width direction as a top. The inclined separating surface holds leading edges of sheets stacked on a sheet holder. At the middle of the inclined separating surface, a sheet separating unit, which extends in a sheet advance direction, is provided so as to protrude from and retract into the inclined separating surface. With this structure, the leading edges of side areas of the sheets do no contact the inclined separating surface before the leading edges of middle areas of the sheets contact the inclined separating surface. Consequently, the leading edges of the middle areas of the sheets are surely applied with separating action by the sheet separating unit.

摘要： An image recording apparatus includes an accommodation section, an image recording section, an outer arcuate guide member, an inner arcuate guide member, and a feeding section. Recording media are stacked on the accommodation section. The image recording section forms an image on a recording medium conveyed in a conveyance direction. The outer arcuate guide member connects in a U-shape the accommodation section with the image recording section. The outer arcuate guide member guides the recording medium from a downstream end portion of the accommodation section to an insertion port of the image recording section. The inner arcuate guide member is disposed to be separate from the outer arcuate guide member. A passage is defined between the outer arcuate guide member and the inner arcuate guide member. The passage allows the recording medium to displace in a thickness direction thereof.

摘要： A sheet-supply device supplying sheets one at a time from a stack of sheets in a sheet feeding direction. The device includes a slanting plate on which a stack of sheets is mounted. A sheet feed roller is positioned above the slanting plate applying a force to an uppermost sheet in the stack to move the sheet in a sheet feed direction. A fixed separation plate is fixed at a downstream end portion of the slanting plate. The separation plate is formed with a slot in which a high friction separation member is disposed. The high friction separation member is held by a resilient support plate 39 supported by the fixed separation plate. The resilient support plate has a comb like slats on which the high friction separation member is held. In a normal condition, the high friction separation member protrudes from the slot toward the leading edges of the sheets. When a leading edge of the sheet presses the high friction separation member by the rotation of the sheet feed roller, and the sheet has a predetermined stiffness, a part of the high friction separation member sinks into the slot by the deformation of the comb like slats.
