Operation control device for camera |
摘要 |
A device for controlling the operation of a camera includes a speed governing member arranged to be operated by a driving force differing from a driving force used for driving shutter blades. The opening speed of the shutter blades is stably controlled by the speed governing member. The control device retards the speed of a shutter blade opening action to enable an automatic focusing action to be performed before the photo-taking aperture actually begins to open after commencement of the shutter blade opening action.
