ABSTRACT:
A photographic information input device for a camera in which a correction effectiveness variable switch for controlling the effectiveness-ineffectiveness of a correction switch of photographic information is provided in a lidded recess of the camera body. When this recess is closed, the correction effectiveness variable switch is made not operable. With the lid opened, when the correction effectiveness variable switch is operated, the effective state of the correction switch is latched, later making it possible to correct the photographic information merely by operating the correction switch. Further, when the lid is closed, the correction switch is automatically changed over to the ineffective state.
