PURPOSE:To reliably feed out a sheet film to a photographing portion sheet by sheet by pushing down the leading ends of sheet films on the photographing portion side except the uppermost sheet film to separate the uppermost sheet film from the other sheet films. CONSTITUTION:A return needle member 16 is rotated clockwise and moved parallel by rotation of a driving shaft 5 to engage a return needle 16' with the uppermost sheet film F (e.g. X-ray photographing film). Subsequently, the return needle member 16 is rectilinearly moved in such a manner as to return in the opposite direction to a photographing portion, so that the central portion of the trailing end of a sheet film F' is inserted in a slit (a) formed by slit members 18, 19. After that, the return needle 16' is separated from the sheet film F', and a film pressing roller 48 is pushed down by the operation of an up-and-down cam 53, thereby pushing down the leading ends of sheet films F on the photographing portion side other than the uppermost sheet film F' to separate the uppermost sheet film from the other sheet films. In such a condition, a feed-out finger 41 is moved to the photographing portion by the operation of a cylindrical cam 27 to feed out only the uppermost sheet film F' between photographing portion feed rollers 58 and 60 with the finger 41. |
