发明名称 FILM CASSETTE FOR USE IN ENDOSCOPE AND DEVICE FOR PRESSING FILM
摘要 PURPOSE:To keep flatness of a film in photographing, and to reduce size of an endoscope camera in the optical axis direction, by providing elastic plates for pressing a film face between feeding and winding chambers or protruding and approaching the film and also forming an exposure opening. CONSTITUTION:Elastic pressing plates 31, 32 are provided on the outlet of a film 21 feeding chamber 22 and the inlet of a film winding chamber 23, respectively, and also they have a function of a frame for defining a prescribed border of the face to be exposed with their ends. The film 21 is pressed on its emulsion side 21A, with the other side of the film 21 pressed by the rail side 33 of an endoscope camera, thus permitting flatness of the film 21 to be held, sharp photographing to be executed, and the size of the camera in the optical axis direction to be reduced because the pressing plates are arranged on the cassette side as compared with the conventional structure where the pressing plates were fixed on the camera side.
