ABSTRACT:
A sheet feed mechanism for attracting and feeding stacked sheet-like members such as photographic films, one by one from a magazine, has a suction cup for developing a vacuum to attract the sheet-like members under suction. The suction cup comprises a base body including a panel member having an opening extending from one surface to another surface thereof, the opening being adapted to be connected to a vacuum source. The base body further includes a peripheral wall, joined to the other surface of the panel member and having wavy edges. The suction cup has a flexible suction skirt attached to and extending from the wavy edges of the peripheral wall, the flexible suction skirt being pressable against a sheet-like member.
