Abstract

A photographic camera of an automatic exposure control type has an electrical shutter of electromagnetic release type and also has a front cover slidably disposed across the front surface of a camera body between a first position in which it closes a taking lens and a second position in which it exposes the taking lens. The camera comprises a first, a second and a third switch which are mechanically associated with the front cover, a rear lid of camera and a film winding mechanism of camera, respectively. The second switch may be replaced by a switch which is mechanically associated with a film frame counter. These switches are connected in an electrical shutter circuit in a manner such that a shutter release operation is disabled in the first position of the front cover, but is enabled in the first position of the front cover whenever the rear lid is opened, thus enabling a film loading operation.
