ABSTRACT:
A camera of the type that receives a film cartridge in a cartridge receptacle and secures the cartridge by a door is provided with apparatus for regulating exposure in response to the combination of (1) sensing a film speed indicator carried by the cartridge and (2) closure of the receptacle door. When a cartridge is inserted into the receptacle and a predetermined film speed indicator is present, an indicator sensing member positions an intermediate lever in a ready position to adjust the exposure regulating apparatus. During closure of the receptacle door, a driver element, located to be engaged and moved when the receptacle door is closed further positions the intermediate lever, which in turn adjusts the exposure regulating apparatus.
