A part to prevent film displacement is moved to one of a contact position with a film and a removed position from the film. The part to prevent film displacement prevents a film displacement toward the direction of advancing film at the contact position. A driving device drives the part to prevent the film displacement. The photography control device carries out one time photography and the film advancement during the single mode setting and carries out the operation of photography and the film advancement alternately and repeatedly during the release operation.
