ABSTRACT:
An operation mechanism for a camera which performs sequential actions by engaging with and disengaging from an electromagnetic driving member moved by an electromagnetic force is arranged to be capable of disengaging from the electromagnetic driving member by its own operating force. Therefore, the electromagnetic driving member does not require any large magnetic force for the disengagement.
