Abstract
PURPOSE: To automatically obtain an optimum photographed image by making light transmissive windows for discriminating the kind of a film near an end portion of the winding side of a cassette film.
CONSTITUTION: One, two or three light transmissive windows 15 for discriminating the kind of a film are made in a lower portion of film 10 on this side of winding chamber 11 correspondingly to the film of ASA 50, 100 or 200, and light transmissive through hole 16 is bored in film leading inlet 11c. By charging film cassette 6 into a camera and running film 10 by a fixed length to prevent fogging, windows 15 pass through hole 16, and light is discontinued correspondingly to the no. of windows 15. An electric signal formed is sent to exposure quantity control section 20, where predetermined operation is performed, and a light source unit is automatically controlled to such quantity of light as provides exposure conditions optimum for the sensitivity of film 10.
