Claims

[Scope of utility model registration request]

When the film cartridge is loaded in the cartridge chamber of the camera, it presses into contact with the loaded cartridge, and the sharp tip penetrates the paint film on the outer surface of the cartridge and becomes electrically conductive with the metal surface of the film cartridge body inside the paint film. A camera characterized in that a conductive member is disposed in the cartridge chamber, and the conductive member is electrically connected to the ground of the camera.
