<P>PROBLEM TO BE SOLVED: To provide the opening and closing structure of a lid body which reduces the component cost and assembly man-hours while making the opening and closing operation simple. <P>SOLUTION: The lid body 17 and a camera main body 10 are connected through a hinge component 24. The hinge component 24 is constituted of a thin sheet type super elastic shape memory alloy, while a plurality of slits 26 are formed on an elbow 27 bent by the opening and closing of the lid body 17 and a shape is stored under a state that the lid body is opened. The sliding operation of the rid body 17 into the direction of an arrow sign (a) with respect to the hinge component 24 is effected whereby the engagement with the camera main body 10 is released, and the lid body 17 is pivoted into the direction of an arrow sign (b), thereby obtaining the opened state automatically. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
