ABSTRACT:
A camera has an image format altering mechanism that includes at least one light buffer blade which is arranged to be inserted into and retracted from an aperture of the camera to thereby determine a picture image area. The camera also includes a camera back hinged to a body of the camera so as to be opened and closed, and an image format selecting member provided on the camera back to move the light buffer blade, the image format selecting member being movable between a position corresponding to a retracted position of the light buffer blade and a position corresponding to an inserted position of the light buffer blade. The camera is also provided with a buffer blade biasing member for biasing the light buffer blade towards one of the retracted position and the inserted position, so that the light buffer blade is located at the retracted position or at the inserted position when the camera back is opened, regardless of the position of the light buffer blade before the camera back is opened. A selecting member biasing member is provided for biasing the image format selecting member towards a linkable position at which the image format selecting member links with the image format altering mechanism, independently of the buffer blade biasing member, so that the image format altering mechanism and the image format selecting member are linked with each other when the camera back is closed.
