Abstract
A propsed apparatus comprising a film reel, a film feeder, a vacuum film holder and a mechanism adapted to move the feeder along the plate is adapted for use in the projection-back in process camera device. These members are arranged such that a film which is being unwound away from the reel is gradually sucked onto said film holder with the movement of said feeder guided by the mechanism. The apparatus may include a film cutter for cutting the film after each stroke of said feeder together with a sheet reel having a wound sheet and adapted to supply it for closing up sucking apertures of said holder portion not covered with the film.
