<p>PURPOSE:To start the feeding of a sheet from an inversion means without having an instruction from an operating side by providing a paper passing control means selecting a paper ejecting part except the inversion means, as a paper ejecting means, when the inversion means is selected as a paper feeding means. CONSTITUTION:When a double-side carrying part is selected as a paper ejecting port, the sheet is fed from a paper feeding cassette 1 or 2, printed by an image forming process equipment, and then, fed to the inversion switching part 24 of the double-side carrying part by the switching of a separating nail 23. Then, a separating lug, 30 is switched and simultaneously, an inversion roller 27 is reversely rotated, so that the sheet is carried to an inversion paper standby part 25. When a command that the double-side carrying part is selected as a paper feeding port is carried out, first, it is judged whether the sheet is on standby or not on the inversion paper standby part 25, by an inversion paper presence detecting sensor 31, and next, the double-side carrying part is selected as the paper feeding port. When the double-side carrying part is selected as the paper ejecting port, a prescribed paper ejecting tray 3 or 4 except the double-side carrying part is selected as the paper ejecting port. Then, the sheet in standby is fed on the inversion paper standby part 25, and on a paper ejecting tray after its other surface has image forming processing.</p> |
