Abstract
A camera including an electronically programmed shutter including improved witches closed during operation of the shutter is provided. The shutter assembly includes an opening member and a locking member carrying shutter blade pivotably mounted to the opening member. Actuation of the opening member triggers closing of the switch which closes the current circuit to an electronic flash device at a maximum predetermined lens opening and initiates the shutter closing. The switches are closed by displacement of a transfer member which is positioned in the locus of movement of the opening member. The position of the transfer member may be set by a switch in the flash device through a linking flash slide or may be changed in response to rotation of the camera focusing element.

A camera having an electronically programmed shutter, wherein the shutter is operated by displacing an opening member for opening the shutter blades and rotating a closing member for closing the shutter blades, the camera adapted to receive an electronic flash device, comprising:
- a projecting region formed on the opening member having at least one detent corresponding to a value of a lens opening;
- switch means including circuit interruption means for releasing the shutter locking ring to initiate closing of the shutter;
- a transfer member disposed between the opening member and the switch means, said transfer member displaceable into the locus of displacement of the at least one detent when the flash is mounted on the camera for displacing the transfer member towards the switch means upon contact by the detent on the rotating opening member for displacing the transfer member into contact with the switch means upon the shutter opening to the maximum lens opening, said switch means initiating rotation of the locking member for closing the shutter.
