A camera is constituted in such a manner that the opening and closing states of the shutter are detected in response to various operations which are performed before the operation for feeding a film is started and when it is detected that the shutter is open in the case where it should be closed, the subsequent film feeding operation is inhibited.
With the structure, the film feeding operation is not performed with the shutter opened.
