Abstract

PURPOSE: To fit and hold a convergent light trasmision material with a high precision, by a bracket which stops the convergent light transmission material along the optical axis from both sides, a cushion material which extends in the direction orthogonal to the optical axis of the convergent light transmission material, an adjusting screw which can press the convergent light transmission material, and so on in the exposure optical system of a copying machine.
CONSTITUTION: Optical system housing 12 is placed between photosensitive material drums 11, and slit 13 is provided on the substrate of this housing. Long convergent light transmission material 15 is stopped along the optical axis into a sandwitch by L-shape fitting brackets 14 and 14' standing in both sides of this slit 13. Handle parts 14a and 14a' of fitting brakets 14 and 14' are provided with torsion adjusting screws 23 and 23' and sag adjusting screws 24 and 24'. By this constitution, the influence upon the optical imaging precision dependent upon distortion of the long convergent light transmission material, the precision of the external form of fitting parts, and so on is compensated.
