<p>A dual-sides enlarging method includes following steps: firstly, a photograph paper is entered into an exposing table (120) with its first surface facing an exposing unit (130) to be exposed for the first time; then, the photograph paper is transferred to an overturn mechanism (150) from the exposing table (120); when a front edge of the photograph paper arrived at the overturn mechanism (150) is detected, the overturn mechanism (150) is overturned to make the second surface of the photograph paper facing the exposing unit (130); after that, the photograph paper is transferred to the exposing table (120) from the overturn mechanism (150) to be exposed for the second time. A dual-sides enlarging device comprises a photograph paper input mechanism (110), an exposing table (120), an exposing unit (130), a photograph paper transfer mechanism (140), and an overturn mechanism (150) including a pair of overturn nipping rollers (151), a detector (152), and an overturn mechanism driver (153).</p> |
