<P>PROBLEM TO BE SOLVED: To connect a paper inversion unit provided with an inversion paper feeding means with an inversion delivery path to guide a one face copy paper without curving it greatly and constitute a printer as a device capable of copying on double faces. <P>SOLUTION: The printer 1 is constituted as the device for forming a copy using an electrophotographic system, and two delivery paths are constituted in an upper part through a gate member 10 to deliver the copy. The paper inversion unit 20 is connected with the inversion delivery path to deliver a paper into an inversion delivery tray 23, and a mechanism for guiding a paper into an inversion passage 27 through a gate member 21 from the halfway of the delivery path is provided. A forward and reversely driving roller device 25 and a gate member 26 are arranged at an inlet of the inversion passage 27 to perform operation for inverting the one face copy paper and feeding the paper toward a paper conveyance passage of the printer inside the unit. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
