PURPOSE: A camera shutter is provided to control luminous intensity of an optical path by independently operating blades. CONSTITUTION: A camera shutter comprises a case(100), cores(200,200'), turn tables(300), first and second blades(400,400'), and a guide(500). The case has luminance(110). The core is composed bobbins(210,210') and an end part. The end part has grooves. The turn table is composed of a magnet(310) and a linker(320). The anode and cathode of a magnet face the groove. The magnet is fixed to the case to be rotated. The linker has side part(323) and a connection part(324). One end of the first blade is fixed on the linker to rotate the first blade along the shaft of the rotary rod. |
