To provide an auto film loader capable of facilitating the additional loading of a photographic film.

Four pairs of nipping and conveying rollers 21 are arranged in a film holder 11. The leading end of the photographic film 14 is nipped by the pairs of the rollers 21, and a one-way clutch prevents the photographic film 14 from falling down. The film holder 11 is loaded on a holder rack. A holder intermittent-moving part and a film sending part are arranged in the holder rack. Respective pairs of the rollers 21 are successively positioned in the film sending part by the holder intermittent-moving part. The photographic film 14 is sent to a processing position by the film sending part while rotating the pair of nipping and conveying rollers positioned at the lowest stage. The film supporting part 13 includes an endless belt 60, a supporting roller 62 and an intermittent rotation part for intermittently rotating the endless belt 60. The endless belt 60 is intermittently rotated by the intermittent rotation part only by the amount of one pitch in synchronism with the feeding of one photographic film 14.
