Yashica FX-3 User Manual

Operation of Bulb
(1) When the speed change gear is set at B, the convex of B lever is set to the concave of B cam below
the gear.
(2) When depressing the release button, B lever descends and is set to the concave of B cam as in the case
of (1); the lever descends lower than other shutter speeds. The low speed governor gear is locked at
the upper side of B lever.
(3) The mirror box works, the shutter is released, the drive cam rotates, and it stops when hitting against
the coupling plate. (The front sector advances before the hit against the coupling plate.) However, as
the low speed governor is locked by B lever, the operation stops here.
(4) When lifting (freeing) the release, B lever ascends, the low speed governor is unlocked, freed and
comes to rotate, then the coupling plate gradually gets away.
* Other operations are the same as the ordinary ones.
Faults that may occur
The shutter fails to close. Because of the flatness of B lever being dis-
Bulb skipping satisfactory, it does not return.
(Change the release-position by SR lever (3)
below the body. Change the bending angle of
the hook of B lever.)
Operation of setting
(1) When lowering the pin of the sector gear to
which the timer spring is applied, the release
lever B plunges into the drive cam.
(2) The timer stop lever rotates clockwise, and
locks the governor gear.
Operation of release
(1) When pushing down the release lever, it is
separated from the drive cam. However,
because the release lever B being hooked, the
drive cam does not rotate.
(2) Further push the release lever, and the timer
stop lever turns counterclockwise, so that the
governor gear being freed, it rotates. The
sector gear returns clockwise, too.
(3) Push down the release lever B immediately
before the ending of return of the sector gear,
and the drive cam is freed and rotates.
