Abstract

PURPOSE: To enable a filter plate to be smoothly rotated by small driving force by providing a click stop on the outside circumferential surface of the filter plate.
CONSTITUTION: A turret type filter disc 1 of a television camera or the like is so formed as to permit turning by an operating part 12 via gear trains 8, 9, 10. In this case, a click stop (consisting of a recess and a spring-energized engaging member) had hitherto been provided in the disc plate surface in order to stop the disc 1 in a predetermined position. Because of this, the friction force between the disc receiving part and the plate surface have had large moment. In this invention, the click stop is provided on the outside circumferential surface of the disc and the receiving member is omitted. Since this causes the friction force by the energizing spring of the click stop to be exerted upon the shaft part, the moment becomes small and the disc may be driven by smaller force.
