Abstract:
PURPOSE:To prevent vibration by oppositely arranging a filter block and a visible radiation transmitting filter having an approximately equal mass and shifting mutually both in the reverse direction at the time of changing over the filter. CONSTITUTION:A filter block 9 is arranged adjacently in parallel to three types of stripe-shaped red(E), green (G) and blue (B) filters 9a-9c, and further, the filter block 9 and a visible radiation transmitting filter 2 having an approximately equal mass are fixed onto an annular belt 12 held over two rotatable roller 13 together with the filter block 9 so that both can be faced. Consequently, at the time of changing over the filter, a force to occur at the filter block and a force, in which a size is approximately equal and the direction is the opposite direction, are generated by a visible radiation transmitting filter. Thus, both are mutually cancelled each other and the occurrence of the vibration is suppressed.
