Abstract
A mechanism registers a sheet of film and advances it toward an imaging station for exposure by a laser scanning system. A registration member is located along a surface that receives the sheet and the member is engageable by an edge of the sheet for registering and guiding the sheet toward the station. An urging guide located along another portion of the surface is skewed relative to the registration member and spaced from it so that the end portions of the guide and registration member nearest the station are spaced apart sufficiently to enable the sheet to lie flat on the surface while other portions thereof are sufficiently close together to prevent the sheet from lying flat on the surface. The guide projects above the surface and is tilted away from the registration member so that the guide imparts a component of force onto a sheet resting thereon which urges the sheet toward the registration member.
