ABSTRACT:
A flash camera has a single-piece shutter-opening/closing and shutter-flash synchronization driver that translates in one direction to pivot a pair of shutter blades away from one another and simultaneously push a movable switch contact of a normally open shutter-flash synchronization switch to close the switch. Then, the movable switch contact is spring-urged to move the switch contact to reopen the shutter-flash synchronization switch and push the single-piece driver in a reverse direction to move the blades towards one another. Movement of the blades away from and towards one another uncovers and recovers an exposure aperture to take a picture.
