Abstract
A mechanism in which a latch is movable between a latching and an unlatching position. The latch includes a first arm engageable by a shutter actuator to move the latch to its unlatching position, a second arm for retaining a piezoelectric firing spring in a latched position when the latch is in its latching position and a third arm movable into engagement with a film advance mechanism to prevent short stroke operation during movement of the piezoelectric firing spring to its latched position.
