Camera having a device for marking a used film magazine

摘要

A camera for a magazine film has an automatic film-rewinding mechanism, an information-recording device for recording at least the information with regard to a used magazine inside an information-recording section at a specific point of the magazine which is located in the magazine chamber of the camera. An information-detecting device detects the recorded information of the magazine when it is inserted. A blocking device prevents an exposure when a detector signal is present which corresponds to the said information, which means that the entire film has already been used. A control device controls the information-recording device, the detection device and the blocking device in such a manner that the information is detected by the detection device before the information is recorded by the recording device and furthermore an exposure is prevented when the detected information means that the film has been used completely.
