    摘要： In a sheet feed apparatus, sheet feed roller (461) is provided in casing so as to face downstream side of sheet stacking portion (46A) in sheet conveying direction, and conveys sheets in sheet conveying direction. Separation pad (71) is provided facing sheet feed roller, forms, with sheet feed roller, nip portion through which sheets pass, and conveys sheets one by one in sheet conveying direction. Holder (72) fixes and supports separation pad. Mount portion (100S) )mounts holder. An urging member (73) urges separation pad toward sheet feed roller via the holder. Holder is changeable in its posture between a first posture in which separation pad is spaced apart from sheet feed roller so as to release nip portion having been formed therebetween, and a second posture in which nip portion is formed between separation pad and sheet feed roller. Holder includes a contact part (721E) that contacts the mount portion in the second posture.

    摘要： A sheet feeding apparatus includes a sheet tray (46A), a sheet feeding roller and a pair of link members (702). The sheet tray constitutes a loading surface. The sheet tray includes a tray main body (70) and a lifting plate (71). The tray main body is openable and closable with respect to the wall portion 10R). The lifting plate has a pair of first fulcrum portions (71c) disposed upstream of the sheet feeding roller. The downstream side of the lifting plate is rotationally movable up and down around the first fulcrum portions. The tray main body has a pair of second fulcrum portions (701). The second fulcrum portions are configured to be a pivot point for the opening and closing operation of the tray main body. Each of the pair of link members is coupled to the first fulcrum portion and to the wall portion.

    摘要： A sheet feed apparatus (46) has sheet tray (46A), sheet conveyance path (460), sheet feed roller (461), lift plate (71), and guide wall (100). Sheet feed roller is disposed, downstream of sheet tray in sheet conveyance direction, above central portion of sheet tray in sheet width direction perpendicular to sheet conveyance direction, so as to face central portion. Lift plate is movable upward and downward to allow sheet to contact with sheet feed roller. Guide wall is disposed downstream of lift plate in sheet conveyance direction and spaced from lift plate with predetermined gap, to guide the conveyed sheet in diagonally upward direction intersecting placing surface of sheet tray. Both end portions in sheet width direction in front edge portion, of lift plate, facing guide wall are provided with end guide surfaces (71A), respectively, which are inclined upward relative to central portion in sheet width direction.
