Camera

Abstract

A camera for setting the aspect ratio of a photographic image plane and recording information of the set aspect ratio has a full-size frame defining a full-size finder image plane corresponding to a photographing image plane, a vertical mask for vertical trimming of the finder image plane, a lateral mask for lateral trimming of the finder image plane, a shaft supporting the masks, and a camshaft with a cam groove engaged by each of the masks. The masks are moved along the shaft by rotating the camshaft. The visual field range of the finder image plane is changed among a plurality of states corresponding to different aspect ratios. The camera finder visual field frame switching mechanism consists of: a vertical mask for vertical trimming, lateral mask for lateral trimming, cam gear having a cam, vertically movable mask operating member, a vertical trimming switch detecting vertical-mask trimming movement, which is aspect ratio information, and a lateral trimming switch detecting lateral-mask trimming movement positional information which is also aspect ratio information. Another embodiment is provided with a vertical mask for vertical trimming of a finder image plane and a lateral mask for lateral trimming of the finder image plane, which, after the vertical mask retreats from a vertical trimming position, moves the lateral mask to a lateral trimming position. After the lateral mask retreats from the lateral trimming position, the vertical mask is moved to the vertical trimming position.
