In the first embodiment, a bendable link mechanism is provided at the center of the shaft, the link connecting portions are in contact with each other to form a straight line, and a stopper 11c projecting to the other side forms a right angle when deployed. Similar to lower printed circuit board 5
It can be bent 90 degrees. The bending angle of the expansion support 11 can be changed by changing the position of the stopper 11c.

る。As a result, the upper printed circuit board 4 can be unfolded so that the printed circuit board can be easily reworked as in the case of the first embodiment, and the link mechanism is generally less expensive than the ball joint mechanism. Since it is low, there is also an effect that it contributes to cost reduction of the entire apparatus.
