Abstract

PURPOSE:To print an image on a frame where main exposure is carried out by means of sub-exposure by moving an sub-exposing unit integrally with a masking member when the masking member is transferred to a specified position. CONSTITUTION:A photographic paper P is pulled by a photographic paper pulling mechanism 28, is carried by a photographic paper carrying mechanism, and then is pinched by a driving roll 60 on the upstream side and a driving roll 61 on the downstream side. A paper mask which forms a printing area is provided between the rolls 60 and 61. The paper mask is formed of longitudinal masking members which regulate both longitudinal edges in the longitudinal direction of the printing area and of the lateral masking members which regulate both lateral edges in the lateral direction of that. The sub-exposing unit 65 is provided on the upstream side of the printing area; said unit integrally moves with the masking member, which moves in the longitudinal direction, when the size of the printing area is altered; and then it sub-exposes a frame which exists on the upstream side or, the downstream side from the printing area by one frame. Thus, an sub-exposured image is printed on each frame where main exposure is conducted, thereby printing efficiency is improved.
