Abstract

PURPOSE: To increase the accuracy of exposure control and obtain high quality image, by applying the exposure light at constant intensity at every start of exposure, and keeping the intensity of this exposure light constant during exposure period.
CONSTITUTION: An original 3 illuminated by a photographic lamp 4 is captured in a camera bag through a lens 2. The intensity of exposure light is sent into an exposure light control mechanism 6 through a photo detector 5. Storing the reference of the intensity of exposure light depending on the concentration of the original, the information of comparison with the present exposure light intensity is transmitted to a motor control mechanism tank 7. The changes in the exposure light may be confirmed also visually by means of information comparison detection display panel 8. By the information from the motor control mechanism 7, a DC motor 9 is rotated in the counterclockwise or clockwise direction. The light source lamp and lens frame 2 are automatically moved through gear trains 11, 10, 14, 15, 17, so that the intensity of exposure light may be kept constant at every start of exposure. At the same time, this intensity may be constantly maintained throughout the exposure period.
