ABSTRACT:
In an original film discharge mechanism in an inclined-type step and repeat machine that includes a photosensitive material holder having a rearwardly inclined surface for holding thereon a photosensitive material and an original film holder movable along the surface of the material holder, which mechanism includes a discharge part having a surface rearwardly inclined at substantially the same angle as that of the surface of the material holder with respect to the horizontal for receiving thereon the original film discharged from the film holder, and a supporting member for supporting the original film removed from the film holder, the improvement includes suctions provided on the surface of the discharge part for suction-holding the original film being discharged onto the part from the film holder, the suctions being positioned upward of and remote from the supporting member along the surface of the discharge part at a distance larger than longitudinal size of the original film; the film holder and suctions being adapted for relative movement away from each other while the latter suction-holding the film to thereby release the film from the film holder; and whereby the original film so released is permitted to be supported at a lower end thereof by the supporting member after the suctions stops so suction-holding.
