PURPOSE:To obtain double-faced copies from double-faced originals automatically without changing the order of page of originals at all and eject transfer paper in the same order of page as originals, by providing switching pawls to invert originals. CONSTITUTION:In a cyclic double-faced original automatic supply device A, a switching pawl 12 switches the first original paper path 1a and the eighth original paper path VIIa. A switching pawl 13 switches the fourth original paper path IVa and the sixth original paper path VIa. Sensors 14, 15, 16, 17, and 18 detect the front end or the rear end of the original paper in the movement direction. In a double-face copying machine body B, the lower end of the third transfer paper path IIIb is connected to the sixth transfer paper path VIb, and the upper end of the fifth transfer paper path Vb is connected to the sixth transfer paper path VIb and the fourth transfer paper path IV, and the upper end of the fourth transfer paper path IVb is connected to the first transfer paper path I b. |
