PROBLEM TO BE SOLVED: To miniaturize the scale of a hinge and to improve the durability of a flexible printed circuit board by connecting freely turnably an upper lid through a link mechanism to a casing. SOLUTION: In the state of opening a cover panel 101 toward a main body 100, a hinge cover 307 is pushed by the cover panel 101 and moved down almost along with a side face 100A of the main body 100. At such a time, a crank arm 401 linked by the hinge cover 307 and a rod (c) is turned with a rod (d) as a center, and the interval of the main body 100 and the hinge cover 307 is widened. Thus, the degree of freedom in the position of a flexible printed circuit board 407 is improved and the durability of the flexible printed circuit board 407 is improved. Further, since a margin can be secured for the length of the flexible printed circuit board 407, the cover panel 101 can be opened up to the angle of 180 deg. to the main body 100. |
