<p>PROBLEM TO BE SOLVED: To provide a paper inversion device capable of being manufactured comparatively inexpensively and stably inverting a surface and a rear surface of a paper fed into without performing extra control. SOLUTION: A conveyance roller 21 and a conveyance auxiliary roller 22 are arranged by differing their positions in the assembly and deviating rollers 31 and 32 in the axial direction mutually. An inversion roller 23 is provided so as to follow the conveyance roller 21 and rotate, and the inversion roller 23 and an inversion auxiliary roller 24 are arranged by differing their positions in the assembly by deviating rollers 33 and 34 in the axial direction mutually. Furthermore, a pair of guide members 28, 28 pressing the paper conveyed onto the inversion roller 23 against the inversion roller 23 are provided. Consequently, the paper is pressurized on the inversion roller 23 by the guide members 28, and the direction of advance is changed by a conveyance force by the inversion roller 23 to convey the paper securely by a simple configuration in which the inversion roller 23 is merely rotated in one direction at all times continuously.</p> |
