Lighting system. Provides illumination of the work surfaces and controls.
There are three illumination devices on the machine:
(1) OMI lamp. Provides illumination for OMI. The lamp rests in an adjust-
able mount beneath a lens and mirror system within the OMI periscope. It provides
an even illumination of marks on the glass rule through this focusing system so they
can be displayed on OMI screen.
(2) OCL lamps. Two lamps within top frame of machine shine between knife
carrier and clamp to produce a thin cutting line on the table bed. The line shows
where the knife will cut when it comes down so that material to be cut can be
positioned. The position of lamps can be adjusted via two knurled knobs on back of
frame to produce the best cutting line.
