Abstract
The present invention provides a shutter apparatus and a drive method for the same, the shutter apparatus having functions of both a shutter apparatus for an image interception and a shutter apparatus for an aperture adjustment and being space-saving and low in costs. Within an illumination casing are provided first and second shading platesand, first and second cammed gearandhaving a cam grooveandrespectively for driving the first shading plateand the second shading platerespectively. A cam shape is structured such that the rotation of a DC motor(one drive source) enables the first and second shading platesandto drive independently. Thus, arbitrarily operating the functions of both the shutter apparatus for the image interception and the shutter apparatus for the aperture adjustment by the DC motor(one shared drive source) is possible.
