ABSTRACT:
A device for transporting individual sheets to or from a magazine housing containing the sheets in a stack, particularly useful in x-ray installations, includes a threaded rotary screw member disposed within the magazine containing the stack of sheets for raising and lowering the sheet stack within the magazine and individually handling the uppermost sheet in the stack for transport to or from the magazine. A sheet transport is also provided comprising drive rollers disposed in a lateral plane overlying the sheet stack and running rollers connected to an upper end of the rotary screw member for movement in a lateral plane directly beneath the drive rollers, such that the running rollers may be disposed between the bottom circumferential portions of the drive rollers to form a sheet transport nip between the corresponding rollers. When an individual film sheet is to be conveyed to or from the magazine housing, the running rollers are positioned beneath the drive rollers pressing the transported sheet therebetween and the drive rollers are rotated to bring about transport of the sheet.
