PROBLEM TO BE SOLVED: To provide a shutter device which can be made thin and has the small number of parts by arranging a shutter blade in such a position that the shutter blade doesn't interfere with an actuator. SOLUTION: A shielding part 27b capable of opening and closing an aperture part 26a is formed in one end part side of a shutter blade 27 in the shutter device, and a support projection 23b of a first guide member 23 is engaged with and supported on a support groove 27c in the other end part side. When the actuator comprising a magnet 25 and a coil 30 is driven, the first guide member 23 is turned along one surface of a base member 26, and the shutter blade 27 is turned with a shutter blade support part 26d as a support point to allow the shielding part 27b in one end part side to open and close the aperture part 26a. The shutter blade 27 opening/closing the aperture part 26a is arranged in such a position that the shutter blade doesn't interfere with the actuator. COPYRIGHT: (C)2005,JPO&NCIPI
