PURPOSE:To reduce the cost and make a copying machine small-sized by providing a paper feeding cassette for duplex copying so that it can be freely moved between the paper receiving position and the paper feeding position. CONSTITUTION:A copying machine body 1 is provided with a photosensitive body 2, a paper feeding device B, and an ejecting roll 10, and a copy paper tray 9 is provided in the exit side of the roll 10 so that this tray 9 is freely moved to positions higher and lower than the exit of the roll 10. A paper supply cassette 14 for duplex copying is provided to move freely between the paper receiving position facing the exit side of the roll 10 and the paper feeding position facing a paper feeding roll 15 for duplex copying. A paper whose one face copying is over is stored when the cassette 14 is moved to the paper receiving position, and a paper whose duplex copying are over is ejected to the tray 9 when the cassette 14 is moved to the form feeding position, thus performing duplex copying. Thus, the structure is simplified, the cost is reduced, and the copying machine is miniaturized. |
