Specifically, the operator can attach the wireless case 5 to the main body chassis 61 or remove the wireless case 5 from the main body chassis 61 simply by moving the wireless case 5 along the radial direction DR. This facilitates inspection of the wireless communication unit 4 and repair of the wireless communication unit 4 .

Further, according to the present embodiment, the vertical length of the projecting portion 531 substantially matches the thickness of the main body chassis 61 . Therefore, when the protruding portion 531 is fitted into the main body through hole 633h, the second holding surface 61b of the main body chassis 61 and the lower surface of the protruding portion 531 are flush with each other. In other words, the third engaging portion 53 does not protrude below the second holding surface 61b of the main body chassis 61 . This improves the adhesion between the light source substrate 70 and the main body chassis 61 . Therefore, the heat emitted from the light source substrate 70 is absorbed by the main body chassis 61 and is easily radiated to the outside.
