In the present embodiment, a USB port 31a for fitting a USB connector of a wireless receiver (not shown) to the side surface of the set top box 30 (hereinafter abbreviated as “STB30”) is rotated about the axis in the USB connector insertion direction. It is provided freely.

  One USB port 31 a is provided in the female connector 31 that is rotatably accommodated in the case 32 of the STB 30. The female connector 31 is connected to a connector 34 via an electric wire 33, and the female connector 31 is connected to the circuit board 35 by fitting the connector 34 with a connector 36 provided on the circuit board 35.

  A circular rotating plate 37 having an opening 37a for exposing the USB port 31a to the outside of the case is attached to the front side of the female connector 31 where the USB port 31a is provided. Specifically, the front side of the female connector 31 is placed on an L-shaped holding part 37b provided at the lower corner of the opening 37a of the rotating plate 37, and the locking is provided protruding from the upper end on the front side of the female connector 31.

Specifically, as shown in FIG. 8A, the female connector 31 is attached to the STB 30 with the long side of the USB port 31a in the horizontal direction.
When the USB connector of the wireless receiver is fitted to the USB port 31a and the wireless receiver is rotated clockwise around the USB connector, the female connector 31 of the STB 30 and the rotating plate 37 follow and rotate in the clockwise direction. Rotate. When the wireless receiver is rotated approximately 90 degrees in the clockwise direction, as shown in FIG. 8B, the protrusion 37d of the rotating plate 37 and the protrusion 32c of the case 32 interfere with each other and do not rotate further in the same direction. I am doing so.
Conversely, when the wireless receiver is rotated counterclockwise around the USB connector, the female connector 31 and the rotating plate 37 of the STB 30 follow and rotate counterclockwise. When the radio receiver is rotated approximately 90 degrees in the counterclockwise direction, as shown in FIG. 8C, the protrusion 37d of the rotating plate 37 and the protrusion 32d of the case 32 interfere with each other and rotate further in the same direction. I try not to.
In addition, the wireless receiver can be held at the required angle by the frictional force generated between the annular groove 32b of the opening 32a and the peripheral edge of the rotating plate 37.
