Abstract
PURPOSE: To detect and display the photographing information such as the frame number of film and sensitivity in the absence of contact by opposedly providing an ultrasonic wave vibrator and a receiver with the film having information holes such as film sensitivity besides the perforations of the films in-between.
CONSTITUTION: An ultrasonic wave vibrator 12 and a receiver 13 are opposedly fixed with the perforations 2a of a film 2 in-between and the respective terminals are connected to a frame number detecting circuit 14. The ultrasonic waves emitted from the detecting circuit 14 are detected through the perforations so that the photographed frame number is displayed. Near the film feed shaft 4, an ultrasonic wave vibrator group 15 and receiver group 16 are fixed with the central part of the film 2 in-between and are connected to the detecting circuit 17. Arrangement is so made that the ASA sensitivity is displayed by the detecting circuit 17 through the ASA information hole group 18 formed in the film. Thereby, the device may be miniaturized and the photographing information detected and displayed in the absence of contact.
