Abstract
PURPOSE:To assure the feed of film, by providing a pair of ball contacts that are energized toward a camera main body by a spring and have contact with a conducting part of the camera main body through the perforation part of film at a position where the perforation part of a camera film pressure plate passes. CONSTITUTION:Ball contacts 2 and 3, when film perforation reaches these contacts, have contact with the conducting part of a camera main body through the perforation. Then the current flows from a power supply within circuit construction through a spring 4, the ball 3, the camera main body, the ball 2 and a spring 5. As a result, a display device within the circuit construction works. When the intermediate part of the film perforation reaches the contacts 2 and 3, the circuit provided between the balls 2/3 and the camera main body is turned off. Thus the display device has no operation. If an LED, etc. is used for the display device, the display blinks every time the film perforation passes through the ball contacts. In such way, the film feed is confirmed.
