Abstract:
1. A sheet feeding apparatus to which a cassette accommodating a sheet is detachably mountable, said sheet feeding device comprising: supplying means for supplying the sheet from said cassette; a reference member having a reference surface for regulating a position of a lateral edge of the sheet being fed in a predetermined feeding direction by said supplying means; feeding means for feeding the sheet such that lateral edge of the sheet abuts the reference surface; moving means for selectively moving said reference member in response to mounting of said cassette; and orientation control means for controlling an orientation of the sheet to abut the lateral edge of the sheet to said reference member, before said feeding means feeds the sheet while contacting it to the reference surface; wherein said reference member comprises a first reference member for regulating a position of a lateral edge of a sheet having a first width, and a second reference member for regulating a position of a lateral edge of a sheet having a second width which is larger than the first width, wherein said moving means moves the first reference member to a position not regulating the lateral edge of the sheet when a cassette accommodating the sheet having the second width is mounted, wherein the first reference member and the second reference member regulate the lateral edges at opposite sides, and wherein in the case that the sheet having the first width is fed, said orientation control means controls the orientation of the sheet so as to incline the sheet to make a trailing end of the sheet closer to the first regulating member than a leading end of the sheet, and in the case that the sheet having the second width is fed, said orientation control means controls the orientation of the sheet so as to incline the sheet to make a trailing end of the sheet closer to the second regulating member than a leading end of the sheet.
