Lens Shutter の性能に就いて
ON THE PROPERTIES OF LENS SHUTTER
市川, 誠
A shutter is an indispensable mechanical element and its property has important effects on cameras, but the study of the shutter has not yet been made sufficiently. Hereupon, of the three types of lens shutter (namely COMPER, PRONTOR and VARIO type), I have investigated the exposure time, exposure efficiency, exposure fluctuation and properties and velocity when it is opened and shut. From my experimental results, I have pointed out the fault of their inechanism and have suggested a new correct mechanism of the lens shutter. Moreover, this experiment has been done as part of study of im-provement of the lens shutter.
