Abstract
This patent application pertains to a camera provided with a running assembly arranged upon movement from a first position to a second position to make ready for the next exposure. The running apparatus is biased so to be urged toward the second position. The running apparatus may be locked in the first position against its bias force. An electromagnet release mechanism, responsive to actuation of a shutter release, frees the running apparatus from its locked condition by the electromagnetic force from the electromagnet.
