  • Light scanning system for a stimulable sheet including vacuum and roller sheet holding means
    Patent number: 5025157
    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.
