FILM GATE ASSEMBLY
A. Aperture Plate ( Film Gate) Assy
1. Description
The aperture plate (4) is mounted on the gate plate (1) by two nuts and can slide up and
down for framing adjustment. The outer guide rail (8) is fixed to the gate plate by two
screws. The movable inner guide rail (12) is mounted by two shoulder screws and adjusted
by the side pressure spring (14). The side pressure control lever (10) is linked to the film
loading mechanism controlled by the function switch, opening and closing the inner guide
ra ii.

Adjustment
a. Tension of the Side Pressure Spring
The proper tension is about 60 - 75g. Excessive tension will cause earlier film wear,
while insufficient tension causes an unsteady picture. The adjustment of tension can be
made by bending or straightening the spring. A weak or incorrectly formed spring
should be replaced.
b. Outer Guide Rail Position
When the film is loaded, the center of the film should align with the center of the
aperture. To accomplish this, adjust the position of the outer rail.
