( 3 ) X - D r i v e.
Movement of the negative parallel to the tilt axis is
controlled by the X-drive.
The primary driving member is the X-drive spindle which
is actuated through miter gears by rotating the X-drive knob. As the X-drive spindle
rotates, movement is transmitted to the X-drive thrust arm by an internally mounted
n u t .
The thrust arm is held between the right bushing supports which move with
it. Since the lamphouse is suspended from the four bushing supports by Y-slide
shafts, it will move with the bushings as they slide along the X-slide shafts.

c. Lens and electronic shutter assembly.
110V ac is applied to CR1 and CR2.
The output of CR2 is filtered by C2 and coupled to R2 and CR5. CR6 limits input
voltage to shutter speed control to 120 V. NE2 indicates the presence of voltage
when it glows.
C3 is charged through the resistor in the SHUTTER SPEED control.
