Abstract
Camera exposure control apparatus utilizing an electronic timing circuit connected to an electromagnet for controlling, through a drive member, the movement of a shutter which opens and closes to establish an exposure interval. A latch, actuated by movement of the drive member to open the shutter, opens a switch to de-energize the electromagnet and moves into position to hold the drive member to prevent its movement to close the shutter during the time interval that the electromagnet is de-energized. Following a subsequent energization of the electromagnet the latch is released and the drive member moves to close the shutter.
