Abstract
Disclosed is a sheet feeding device for printers and the like, which comprises a detachable holder for thick cut sheets. In this device, thin ordinary cut sheets, supported in a pile by paper supporting means, are delivered one by one in a sheet feeding direction by feed rollers, which are in contact with the uppermost one of the sheets. In feeding relatively thick cut sheets, such as postal cards and other cards, the holder carrying the sheets thereon is detachably mounted on the supporting structure. The holder includes a supporting member for supporting the leading ends of the thick cut sheets, with respect to the sheet feeding direction. The supporting member has a slanting or curved guide surface. As the feed rollers rotate in contact with the uppermost one of the thick cut sheets, the sheets are delivered, sliding on the guide surface.
