Abstract

PURPOSE: To effect free and continous change of light transmitted through a color filter plate by displacing one or both of the filter plate and a lnes plate by means of a displace device.
CONSTITUTION: A color filter plate 5 consists of belt-like red filters 6, blue filters 7, and green filters 8 arranged sequentially and in parallel. A spring 10 is fitted on one side of the lens plate 3, with one end of the spring 10 secured to the plate 3 and the other to a fixer 9. The other side of the lens plate 3 is in contact with an eccentric cam 15 fitted to an end of a shaft 14 extending from a gear train 13, and the gear train 13 is coupled to a drive shaft 12 of a stepped advancing device 11 consisting of a motor such as synchronous motors. The stepped advancing device 11 is connected to a variable frequency switch circuit; the rotation of the stepped advancing device 11 is reduced through the gear train 13 and the cam 15 is rotated slowly to displace the lens plate 4.
