Claims

[Claims for Utility Model Registration] 1. If the film loaded in the camera body is transferred, the light emitted from the light emitting part will not reach the light receiving part if the perforation is covered in the front surface, and the perforation is not provided. A photo sensor is arranged to face the movement area of the perforation of the film so as to reach the light receiving part when the part comes, and the detection display drive circuit is actuated by the output from the photo sensor to cause the detection display means to blink. A camera film advance detection device characterized by: 2. A switch is provided in the camera body that is activated when film is loaded in the camera body, and when the film is not transferred, the detection display means is turned on by activation of the switch. A film advance detection device for a camera according to claim 1, characterized in that:
