Abstract

PURPOSE:To control exposure and obtain a sufficient quantity of adjustment with a small space by constructing so as to rotate a douser to adjust a light quantity incident to the sagittal direction of a lens with a knob rod. CONSTITUTION:A mounting frame 10 is mounted in the fitted form to a retaining tool 9 of a lens 5, on the upper and lower parts of right and left sidewalls 10a, 10b of the mounting frame 10, a pair of the upper and lower dousers 11, 11' is fixed freely rotatably to the upper and the lower direction so as to opposedly approach and separate. On the other hand, a knob part 19a of a knob rod 19 is made easily operatable for rotation from the outside. Thus, the dousers 11, 11' oscillate to the opposedly approaching and separating directions. With such constitution, by adjusting only the quantity of a light incident to the sagittal direction of the lens 5, the exposure can be controlled. The dousers 11, 11' fluctuate to the upper and lower directions, so with the small space the sufficient quantity of adjustment can be obtained.
