<P>PROBLEM TO BE SOLVED: To provide a lid opening/closing mechanism which serves quality upgrading, use expansion, and cost reduction. <P>SOLUTION: A first axis 8 and a second axis 9, arranged on the lid side, respectively fit a first circular arc groove 20 and a second circular arc groove 21, which are arranged on the main body side and serve as guide grooves, and rotate guided by the first circular groove 20 and the second circular grooves 21 by sliding. By receiving energization or energized resistance from an energization means 5 arranged between the main body side and the lid side, the lid can be switched from a close state in which the first axis 8 is positioned at one end 20a of the first circular arc groove 20 while the second axis 9 is positioned at the other end 21b of the second circular arc groove 21, to the open state in which the second axis 9 moves to the one end of the second circular arc groove 21 by sliding with the first axis 8 as the fulcrum after the first axis 8 moves to the other end of the first circular arc groove 20 by sliding with the second axis 9 as the fulcrum, and also the lid is held energized in the close state. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
