As shown in the figure, 1 is a chassis, and a printed circuit board holding fixture 2 has flanges 2a and 2a' at both ends, and the flange parts 2a and 2a' have a rotation hole 2b approximately in the center.
2b', notches 2c, 2c' are provided at the ends, and grooves 2d, 2d' continuous to the rotation holes 2b, 2b'.
is provided. This printed circuit board holding fitting is fixed with a printed circuit board 3 screw 4. On the other hand, on the main body side of the device, there are protrusions 1a and 1a' on the chassis 1.
A nail-shaped retaining portion is formed on this protrusion 1a.

回転穴２ｂを差し込む。Therefore, first, as shown in FIG. 3, a printed circuit board unit incorporating the printed circuit board 3 and the printed circuit board holding fitting 2 is assembled into a printed circuit board unit 9. Hold the board vertically and insert the protrusion 1a of the chassis 1 and the rotation hole 2b provided in the printed circuit board holding fitting 2.

Since the protrusion 1aK has the stopper part 1b, even if the printed circuit board unit is moved in the Z direction shown in FIG. 1 from this state, the printed circuit board unit will not fall off. Next, when tilting the printed circuit board unit in direction B in Fig. 3, lift the printed circuit board unit upward.
The protruding portion 1a is removed from the groove 2d, and the notch 2C is removed from the chassis hook portion 1C, allowing the chassis to be folded down. When rotating the printed circuit board from the state shown in Fig. 2 in the Y direction, use the protrusion 1a.
rotates as a fulcrum, and when it stands up at tQt as shown in Figure 3, the weight of the printed circuit board unit automatically lowers it down and allows it to be held again as shown in Figure 4.
