To easily switch film photography and electrophotography.

At the time of film photography, an image pickup element 8 is used as a pressing plate for a silver salt photographic film 12, and the film photography is performed by making the image pickup element 8 in a non-actuated state at the time of detecting the presence of the silver salt photographic film, and the electrophotography is performed by making the image pickup element 8 in an actuated state at the time of detecting the absence of the silver salt photographic film. Thus, the film photography and the electrophotography are easily switched without changing the back cover of a camera, so that operability is improved. Even when the film is used up, a photographing chance is not missed and an optimum photographic form in accordance with a photographic scene is selected.
