SECTIONV
Shutter
The
Eclair 16
shutter is characterized by its large diameter and the fact
that it rotates only once per image. It has therefore only one blade
which, by passing very close to the aperture, ensures maximum defini
tion. As it cuts the aperture horizontally, it reduces to the minimum the
stroboscopic effect of other systems.
The shutter opening is adjustable (with the camera stopped) between
5
°
and 180
°
. The adjustment is in steps of 10
°
between 10
°
and 180
°
.
The adjustment is carried out as follows :
(Before adjusting the shutter, the battery must be disconnected from the
Beala motor).
1. Unlock the turret (E 50) as shown in Section Ill.
2. Turn the turret through 90
°
(photograph D), push it in slightly to
retain the position.
3. Push the lever (E 37) through 90
°
on to "Reflex".
4. Using the knurled wheel (E 36) turn the shutter until the blade covers
about the half of the aperture.
5. Move the lever (E 37) to "reglage obturateur" and keep it in this
position.
6. Push and then rotate the button (C 23) in the direction required to
adjust the shutter. The desired opening is obtained when the cor
responding figure is at the edge of the reflex-mirror.
7. The lever (E 37) automatically comes back to the position "moteur".
For the reflex viewing, if the camera is equipped with our multi-pro
gram "BEALA" motor, the mirror always stops on viewing position.
With other motor it may be necessary to rotate the shutter to bring
the reflex-mirror to the viewing position. This is carried out as follows:
1. Move the lever (E 37) through 90
°
to "Reflex"; it remains in this
position.
2. Turn the knurled wheel (E 36) until the image appears in the view
finder.

3. Push lever (E 37) back to its initial position (motor). If operation 3 has
not been carried out, the camera will run noisily and may not run at
the correct speed. However, no damage can result in this condition.
