PURPOSE:To prevent the unevenness in printing and staining of a picture and to increase the speed of operation by providing two destaticization electrode rolls and two staticization rolls, i.e. four rolls rotating in contact with two superposed photographic films. CONSTITUTION:On metallic head 1, unexposed film 2 and negative film 3 on it are placed and destaticization roll 4, staticization rolls 5 and 6, and staticization roll 7 are run in sequence on them; and light source lamp 8 is provided between both rolls 5 and 6 and they are incorporated in a running frame body. When the running frame runs, roll 4 removes dust with static electricity applied to respective rolls 4- 7, and the film is exposed by light source 8 in an electric field between rolls 5 and 6; and roll 7 peels off both films 2 and 3 easily and printing is performed. |
