  • Patent number: 9169092
    Abstract: A sheet feeding device includes a housing, a conveyor roller, a first shaft, a second shaft, and drive units. The conveyor roller includes a first side portion and a second side portion. The first shaft has a first engaging portion. The second shaft has a second engaging portion. The drive units drive and rotate the first and second shafts. The first side portion has an engaged portion to be engaged with the first or second engaging portion. The second side portion is formed with a bearing portion configured to be supported by the first or second engaging portion in relatively rotatable manner. The conveyor roller is mountable in the housing in a first mounted state, in which the conveyor roller is integrally rotated with the first shaft, and in a second mounted state, in which the conveyor roller is integrally rotated with the second shaft.

  • Patent number: 8876104
    Abstract: Sheet conveying path extends from sheet stacking portion. Sheet feed roller is disposed, in sheet conveying path, facing sheet stacking portion. Sheet feed pad is disposed facing circumferential surface of sheet feed roller, and has pad surface that forms, between pad surface and circumferential surface, nip portion into which sheet is conveyed. Support member has support surface to which sheet feed pad is fixed and contact surface located upstream of support surface in sheet conveying direction so as to be higher than pad surface, and configured to make contact with leading end of sheet fed from sheet stacking portion. Rib portions are disposed in support member. Rib portions are disposed on both side portions, in sheet width direction intersecting sheet conveying direction, of support surface, and have inclined surfaces that extend so as to lower front end portions thereof, respectively, from contact surface toward downstream side in sheet conveying direction.
