Abstract
A sheet to be fed by a sheet feed roller is loaded on a sheet feed tray, and a side regulating member is disposed so as to be movable in accordance with the sheet size in order to regulate the position of the loaded sheet in the direction of the sheet width. The side regulating member extends downstream from the sheet feed roller in the sheet feeding direction in order to regulate the position of the sheet in the direction of the sheet width, thereby preventing oblique movement of the sheet.
Claims15
A sheet feeder, comprising:
- a sheet support which supports a plurality of sheets;
- sheet feeding means for feeding sheets from said sheet support;
- sheet conveying means for conveying the sheets fed by said sheet feeding means;
- and
- side regulating means for regulating both side edges of sheets supported by said sheet support in a direction of a width of the sheets, said side regulating means extending downstream from said sheet conveying means in a direction of sheet feeding so as to regulate both side edges of a sheet being conveyed by said sheet conveying means after the sheet passes said sheet feeding means.
