Abstract
This invention is applicable to a camera having a cartridge chamber into which a film cartridge is detachably insertable along its axis direction. The camera is equipped with a cartridge-load detection switch for outputting a load signal when the cartridge is loaded in the cartridge chamber, and outputting a non-load signal when the loaded cartridge is drawn out from the cartridge chamber by at least a predetermined amount. When the photographed cartridge is partially drawn out from the cartridge chamber and then reloaded into the cartridge chamber as it is, the output of the load signal is continued if the draw-out amount is below the predetermined amount, thereby preventing an erroneous judgment that a new cartridge is loaded into the cartridge chamber. Therefore, for example, the double exposure can be prevented.
