LEFT SIDE ASSEMBLY. Consists of column headers, inversor unit, and tilt control
mechanism.
Column headers maintain correct spacing of each pair of columns.
Inversor unit and tilt control is a mechanical linkage system which move lens
support arm and easel along guide bars in proper correlation to maintain sharp
