Abstract

PURPOSE:To prevent a malfunction of photographing, by constituting so that shutter release is locked by patrone detecting signal, and lock of the shutter release is released by a film feed detecting signal. CONSTITUTION:When a film patrone is loaded and a detecting pin 4 is pressed down, a patrone detecting switch is operated and a release inhibiting signal is outputted to an exposure controlling circuit. On the other hand, when a pulse signal from a film feed detecting circuit constituted of a photocoupler 12, etc. incorporated in a film feed sprocket 7 is inputted to a film counter, the release inhibiting signal is released, and after the patrone has been loaded, the shutter can be released only in case when a film is fed normally, therefore, a malfunction of photographing is prevented.
