The power supply housing 47 is electrically connected, and the power supply housing 47 and the power supply unit 48 attached to the power supply housing 47 with screws 70 are electrically connected. The ground can be taken without connecting the bottom surface of the main body S1 and the power supply unit 48 (power supply housing) by the wire. That is, the power supply housing 47 does not need to arrange a ground wire in the main body S1.

  The power supply housing 47 is fixed to the side surface with a separation from the bottom surface of the main body portion S1, but the power supply housing 47 is not limited to this and is only separated from the bottom surface of the main body portion S1. Instead, it may be fixed to the back surface. Thereby, the power supply housing 47 is fixed to the corner of the main body S1, so that the power supply housing 47 can enhance the heat radiation effect of the power supply housing 47 and improve the strength of the main body S1. There are cases where it is possible.

  In the case where the main body S1 is made of metal, the heat released from the power supply housing 47 is released through the metal main body S1, so that the release effect is further enhanced.
