摘要： Device for feeding single sheets out of a stack of film sheets while avoiding the risk of artifacts. The device comprises a housing for housing the stack of film sheets, a driven feed roller in contact with the first film sheet of the stack, biasing means for keeping the stack with its first film sheet in contact with the feed roller, and a withdrawal passageway for the film sheets, characterized in that the passageway is defined by a first guide surface forming an angle of 30.degree. to 60.degree. with the sheets of the stack and a second rounded guide surface, the passageway has a height at least twice the thickness of a single film sheet, and the feed roller has an outer surface comprising a material which provides a coefficient of static friction between that material and a film sheet which is greater than the coefficient of static friction between two adjacent film sheets of the stack.
