Device for actuation of the closure of a camera with automatic exposure control

摘要

A photographic camera with an automatic exposure control means, an exposure time control circuit for initiating the closure of the camera shutter and a film frame number indicating mechanism having non-usable and usable frame indications. A shutter closure urging circuit is operably connected into the exposure time control circuit and has connected therein a switch to render effective and ineffective the shutter closure urging circuit. A lever actuates the switch to render effective the shutter closure urging circuit when the indicating mechanism is providing the non-usable frame indication and for rendering ineffective the shutter closure urging circuit when the indicating mechanism is providing the usable frame indication.
