Abstract

1,109,071. Exposure meters. M. KOMAMURA. July 22, 1965 [April 23, 1965J, No.31355/65. Heading G2A. An exposure meter has a photo-sensitive portion 3 of its front face insertable into a camera of the dark slide type, for use with a dry plate or a cut film, at a position substantially coinciding with and extending over the whole of the image plane of the camera prior to loading. An ammeter 6 connected electrically to the portion 3 is calibrated in values of intensity of exposure. The value of intensity of exposure is converted to shutter speed in accordance with film sensitivity by a conversion dial 7. A switch 9 can be actuated to positions for checking the condition of batteries (4a) and (4b) Fig. 4 (not shown).
