摘要

PROBLEM TO BE SOLVED: To enable the efficient development processing of a photographic film by providing three or more splicing parts in the shapes of connecting the photographic film. SOLUTION: The splicing part 530 of a development leader splicing device 500 splices a development leader 5 supplied from a development leader stock part 510 by a development leader supplying mechanism 520, to the top end of the photographic film 7 stuck out like a tongue from a fed cartridge 3. The development leader 5 has three splicing part holes as the splicing parts in the shapes of connecting the film 7 and the splicing part 530 splices three films 7 whose lengths are almost equal to one development leader 5, as a rule. The cartridge separating part 620 of a development processing part 600 pulls out the film 7 from the cartridge 3 by a spring mechanism 612 and cuts off the tail of the film 7 by a cutter, to separate and eject the cartridge 3. Then, the film 7 has fixed development processing, in accordance with the carrying of the leader 5.
