Abstract
A camera having a detection assembly and method are capable of detecting a top edge or a bottom edge of film. The camera includes a film detection assembly positioned within a camera body to detect one of the top edge and the bottom edge of the film. The film detector assembly includes a force detection assembly that detects a force exerted by one of the top edge and the bottom edge of the film. The film detection assembly also includes a film indication assembly to indicate the presence of film within the camera. The film indication assembly is connected to the force detection assembly. The film indicator assembly includes a switch assembly that opens and closes in response to the absence or presence of film within the camera.
