PURPOSE:To improve the reliability of film information detection by installing a circuit board which can process a film information signal in the vicinity of a cartridge chamber and constituting the circuit board and a contact terminal which detects the film information signal so that they can be connected directly. CONSTITUTION:Holes 5A-5F are formed through a circuit board 5 made of a hard plate and a process circuit IC9 is mounted on the board 5. Electrode patterns 11A-11F installed to the board 5 are electrically connected with the process circuit IC9. Each end of plate springs 8A-8F are soldered to the electrode patterns 11A-11F and the other end pushes each end part of contact pins 7 protruded from the holes 5A-5F against the information sections A-F of a film cartridge 1. In this case, information signals from the information sections A-F are transmitted from the contact pins 7A-7F to the information processing circuit IC9 through the plate springs 8A-8F and electrode patterns 11A-11F. When such a constitution is used, the reliability of film information detetion is improved.
