Abstract: There is disclosed an exposure control device for a camera having a photographic lens of variable focal length type which includes exposure control means for controlling an exposure on the basis of a light coming from an object to be photographed and passing through an optical path different from that of the photographic lens and correcting means for correcting said exposure control means to correct the exposure depending upon a change of an open F-number of the photographic lens caused by a variation of the focal length, by changing a resistance value of a variable resistor or a length of the optical path for measuring the light in response to the variation of the focal length of said photographic lens.

Abstract: A film winding device for a camera including a drive source; a sprocket arranged to be rotated by a film when the film is wound up on a spool of the camera; and a one-way clutch arranged to make the driving force of the drive source transmissible to the sprocket when the input shaft thereof is rotated in the direction of film winding and to remain in a non-transmissive state by virtue of the absolute rotating direction of the input shaft thereof when the input shaft rotates in the direction of film rewinding.
