PURPOSE:To freely constitute a peripheral device regardless of a distance between film and a lens and to facilitate the maintenance and the exchange of an enlarging lens by providing a lens moving mechanism. CONSTITUTION:The enlarging lens 8 and a photographic paper 9 with a lenticular sheet are moved on a plane vertical to an optical axis in order to perform multiexposure for 3D stereoscopic photography. By moving the lens 8 in an optical axis direction(Z direction) between the photographic paper 9 and a negative film 7, printing is performed at a desired enlarging magnification at a positive position near the negative film 7 at the time of printing. In the case of other operation, the lens 8 is retreated from the negative film, and the adjustment of the negative film or the lens is performed. Namely, a stepping motor 1 is connected to a lens plate 4 by a nut 3 through a ball screw 2, and the lens is moved up and down together with the lens plate 4 through a slide rail 5 fixed on a wall surface, etc.
