- the first casing 41 is rotated 180 ° around the second rotation shaft 12.
- the display 41D of the first housing needs to be flush with the display 42D of the second housing. Therefore, the second rotating shaft 12 is not positioned on the overlapping surface F of the first casing 41 and the second casing 42, and the display 41D of the second casing is changed from the display 41D of the first casing.
- the height of the mounting protrusion 15 is made higher than the depth of the mounting recess 42R, and the distance between the rotary shaft 12 from the display 41D of the first housing to the display 42D of the second housing is increased. It is provided on a center line CL that bisects every T.

Then, the first casing 41 does not come out upward with respect to the first rotation shaft 11 due to the protrusion 14 provided on the first rotation shaft 11. That is, the protrusion 14 is a protrusion for preventing the first casing 41 from coming off upward.
- the first semicircular shaft 11A does not rotate around the second rotation shaft 12 with respect to the second semicircular shaft 12A. In this case, it is possible to rotate around the first rotation shaft 11, that is, to the second semicircular shaft 11B side.
- the diameter of the first rotating shaft 11 is drawn large for easy understanding of the configuration, but the diameter of the first rotating shaft 11 is large enough to accommodate the second rotating shaft 12. Good, not particularly limited.
