PROBLEM TO BE SOLVED: To provide compact and thin blade driving device for a camera equipped with two kinds of blade members driven by respective motors. SOLUTION: The 1st stator frame 2 of the 1st motor and the 1st stator frame 7 of the 2nd motor are arranged like one plate by superposing thin areas 2b, 2c, 7b and 7c having 1/2 plate thickness, respectively, and a diaphragm blade 11 is rotatably attached to a shaft 2g and a shutter blade 12 is rotatably attached to a shaft 7g. Then, a cover plate 8 is arranged on a back side, and a screw 9 is made to pass through the hole of the cover plate 8 and the hole 2d of the frame 2 and screwed in the hole 7d of the frame 7, and another screw 10 is made to pass through another hole of the cover plate 8 and the hole 2e of the frame 2 and screwed in the hole 7e of the frame 7. The blades 11 and 12 are rotated to reciprocate by the output pins 1c and 1c of the respective motors. COPYRIGHT: (C)2005,JPO&NCIPI
