<p>PROBLEM TO BE SOLVED: To provide a picture image formation device capable of simplifying a configuration of the device, reducing manufacturing cost and maintenance cost, and improving conveyance performance at the time of inversion paper discharge and double-side printing by realizing a paper inversion function for inversion paper discharge and a paper inversion function for double-side printing by one switch back means. SOLUTION: This picture image formation device is provided with a picture image formation part 20 forming a picture image on one side of a paper P, switch back rollers 91A, 91B switching back the paper on which a picture image is formed on one side, an inversion paper discharge conveyance passage 130 which inverts the switched back paper P and conveys it to a paper discharge part, an inversion paper supply conveyance passage 140 which inverts the switched back paper and conveys it to the picture image formation part 20, and a pair of jogger fences 100 regulating a position of the paper in the orthogonal direction to the paper conveyance direction at the time of switching back. A regulation width of the paper position by the jogger fences 100 can be controlled separately depending on the time of inversion paper discharge and the time of inversion paper supply. Moreover, the switch back timing can be controlled per paper supply tray 10A, 10B.</p> |
