ABSTRACT:
A camera comprises flash circuit board, a shutter-flash synchronization contact conductively connected to the flash circuit board for synchronizing shutter opening and flash illumination, a shutter blade conductively connected to the flash circuit board and movable in a single direction against the synchronization contact as an incident of shutter opening to initiate flash illumination, and an optical film encoder conductively connected to the flash circuit board to receive electrical energy to provide film encoding illumination when the shutter blade is moved against the synchronization contact. The synchronization contact has a resilient extension-contact positioned for the shutter blade to move in the single direction against the extension-contact as an incident of shutter opening to initiate flash illumination and to permit the optical film encoder to begin to receive electrical energy to provide film encoding illumination, and positioned to remain in touch with the shutter blade during further movement of the shutter blade in the single direction to permit the optical film encoder to continue to receive electrical energy for providing film encoding illumination.
