PROBLEM TO BE SOLVED: To easily execute the attaching and detaching operation of a mask. SOLUTION: The mask to position the image frame of photographic film at a printing position and a mask attaching table to attach the mask so as to be freely attachable and detachable are provided, and a rail member where the opposed side part of the mask is slid at the attaching and detaching time of the mask is attached to a frame member 41 by an adhesive at the mask attaching table. The abutting surface of the frame member 41 with the rail member possesses an adhesive part 413 and a non-adhesive part 414, and an interstice G is formed between abutting surfaces at the adhesive part 413, and the interstice G is filled with the adhesive S, so that both members 41 and 42 adhere, and the abutting surface directly abuts at the non-adhesive part 414. Also, the clearance groove part 415 of the adhesive is formed at the periphery of the adhesive part 413, and excess adhesive supplied to the adhesive part 413 is prevented from flowing into the non-adhesive part 414.
