Abstract
An apparatus for manually sending a sheet of paper to the sheet handling machine (i.e., a feeding mechanism inside of a copying machine or printer) equipped with an automatic sheet-feeding cassette. The sheet sending apparatus is composed of an upper chute and a lower chute articulated by gears. When the apparatus is used, the chutes make a flat angle to smoothly pass a sheet to the feed roller and the lower chute press down the stacked sheets of the sheet cassette. When the apparatus is not used, the chutes rotate and the lower chute leaves the feed roller. A sheet guide is attached at the lower end of the lower chute to prevent the sheet sliding on the chutes from falling in the sheet cassette, and the parts of the sheet guide corresponding to the separator of the sheet cassette is removed to allow natural flipping action of the sheet when the sheet is drawn out of the sheet cassette.
