ABSTRACT:
A copying machine operable in a manual copying paper feed mode and an automatic copying paper feed mode which has an automatic paper feeding section and an inlet for receiving copying paper inserted manually. The automatic paper feeding section includes a cassette containing copying paper to be fed automatically, a feed roller for feeding the copying paper, and a lifting mechanism for lifting the copying paper for pressure contact with the feed roller. The inlet has a cover which is opened for manually inserting copying paper, and a guide member for guiding the copying paper to a position between the feed roller and the copying paper contained in the cassette. The manual feed mode is automatically switched to the automatic feed mode when the manually fed copying paper is exhausted and the cover remains closed for a predetermined time during the manual feed mode.
