ABSTRACT:
A light beam scanning system has a sheet holding member which is provided with a concave cylindrical sheet support surface on which a recording sheet is supported. A suction box draws the recording sheet against the sheet support surface by suction. A spinner has a light deflector mirror which reflects a scanning light beam on the central axis of the cylindrical sheet support surface toward the recording sheet on the sheet support surface and a condenser lens system which converges the reflected scanning light beam on the recording sheet. The light deflector mirror and the condenser lens system are integrally rotated about the central axis to cause the scanning light beam to scan the recording sheet in a main scanning direction. A sub-scanning mechanism moves the sheet holding member in a sub-scanning direction parallel to the central axis relative to the spinner. A pair of holding rollers are spaced from each other in the sub-scanning direction with the spinner intervening therebetween and are opposed to the sheet support surface at a distance slightly larger than the thickness of the recording sheet. Each of the holding rollers being fixedly supported relative to the spinner in the sub-scanning direction and being able to freely rotate about a rotational axis which is parallel to the central axis of the sheet support surface.
