Claim Text:
1. A sheet feeding apparatus comprising: a conveyance unit configured to convey a sheet supplied from a holding unit; a sensor configured to detect an edge of the sheet in a width direction; a width detection unit configured to detect a width of the sheet; a storage unit configured to store at least two sets of data of threshold values corresponding to widths of the sheet; and a control unit configured to detect, with the sensor, a displacement of the edge of the sheet in the width direction during movement of the sheet by a predetermined distance, and to cancel a subsequent skew detection operation if the displacement is larger than an allowable amount, wherein the control unit uses the at least two sets of data stored in the storage unit to set a skew threshold value with which the displacement is to be compared, and wherein if the at least two sets of data do not contain a threshold value corresponding to the width of the sheet detected by the width detection unit, the control unit calculates the skew threshold value by using the at least two sets of data of threshold values corresponding to the widths of the sheet.
