PURPOSE:To obtain an image with a focused magnification by compensating the lens and mirror positions corresponding to a selected magnification in accordance with a focal distance error of a lens. CONSTITUTION:A pin 57 fixed on a mirror board 21 provided with mirros 14, 15 and a pin 49 fixed on the end of a lod 47 for a stopper 38 engaged with the notches 36, 37 of a positioning plate 35 are engaged with the fluted cams 58, 51 of a cam plate 50 respectively. When the cam plate 50 is rotated by a motor 52, a mirror board 21 and a positioning plate 35 for a lens 16 are moved along a rail 23 respectively. In said device, the moving distance of the mirror board 21 and the positioning plate 35 can be compensated in accordance with the focal distance error of each lens by loosening a nat 54 to control the rotation of the cam plate 50 around an axis 53. In any magnification mode, a focused image with the magnification corresponding the selected mode can be formed. |
