PROBLEM TO BE SOLVED: To materialize a simple structure and operation by making it possible to operate a plurality of functional controls with respect to illumination light including on/off operation of a light source, through the operation by an identical member in an identical direction.SOLUTION: The cylindrical cam 7 in an illumination apparatus 10 is rotated integrally with a handle 8 when the outer periphery of the handle 8 exposed from the back of a housing 11 is held to rotate the handle 8. A cam surface is formed along the peripheral surface in a side end at the front of the cylindrical cam 7. The side ends at the back of operating plates 5, 6 are brought into contact with the cam surface of the cylindrical cam 7. The operating plates 5, 6 move along the X direction by the displacement of the cam surface when the cylindrical cam 7 is rotated together with the handle 8. The side end at the front of the operating plate 5 is brought into contact selectively with the movable contact 4A of a power switch 4 from the rear side. The side end at the front of the operating plate 6 is brought into contact selectively with the back of a shaft portion 3A extended from a lens holder 3 to the back side. |
