REASSEMBLY AND ADJUSTMENT
FUJICA GS645
5.
Adjustment of focusing (Infinity adjustment)
o
Set the collimater to
00 •
o
Watch the film plane, and fix the
oo
side stopper of the helicoid at the position
where image of the collimater is correctly focused.
o
To adjust, loosen four set screws (4- 51).
NOTE:
Set the film plane within +0.05±0.1 mm (- 0.05 to +0.15 mm) against
the rail plane.
[Set film side to +0.05 mm against the rail plane.]
6.
Adjustment of viewfinder (Coincidence of images)
To adjust coincidence of the stationary image and moving image, the screw (2- 15)
(for height) and eccentric pin (2 - 22) (for left or right) are used.
[Adjustment procedure]
Coincidence of inifinite image
(1)
Apply the lens to the
oo
side stopper and coincide the moving image with the
stationary image.
(2)
Fix the helicoid at the position where an image in 2 meter distance is focused
on the film plane, and watch the coincidence in the viewfinder.
When the image is deviated to the right or left, adjust the eccentric pin (2- 59).
(3)
Check the infinity, and repeat the adjustment until the focusing performance is
within the permissible range (- 0.05 to +0.15 mm).
( 4) Setting infinite image non - sensing band
Adjust the eccentric pin (6- 40) of the linkage assembly (6- 36) so that the
image in the infinite side is in the non - sensing band at
1,4
of the
oo
mark
and thereafter.
[Provide a proper gap by bending the linkage assembly so that
the image coincidence in the viewfinder is not affected even if the engagement
of the interlock lever changes.]
