To read information from a film without causing double exposure even if the film is in an exposed state when the information written in the film is read.

When a film is in an exposed state and in a developed state, a shutter driving operation is forbidden to prevent double exposure in the former case and to eliminate unnecessary photographing in the latter case. In the case of an exposed/developed film, since a zoom SW changes to SW for reading information in the film, a number of SWs are not required.
