Abstract
A sheet feeding apparatus for use in a photocopier or the like in which sheets can be fed automatically from a cassette or manually from a manual-insertion tray to a pair of conveying rollers without interference and using a simple structure. Sheets are fed from the cassette to the conveying rollers with a semicircular roller, the latter having a flat surface which is directed downward at the completion of each sheet feeding operation. The manual insertion tray guides the manually inserted sheets along a path below the semicircular roller. A sensor detects when a sheet has been manually inserted, in which case rotation of the semicircular roller is inhibited.
