The connector fitting portions 1 are provided in the horizontal direction, or as shown in FIG. 14B, all the connector fitting portions 1 are provided in the vertical direction.
In such an electronic device, since the mounting angle of the wireless receiver connected to the connector cannot be adjusted, there is a problem that sufficient transmission performance by wireless cannot be obtained depending on the mounting angle of the wireless receiver.
In order to solve such problems, some wireless receivers have a movable antenna protruding so as to improve reception sensitivity. However, wireless receivers that do not have a movable antenna due to cost and appearance problems are not available. Many.

In the utility model registration No. 3084884 (Patent Document 1), a wireless receiver 2 shown in FIG. 15 is provided, and the wireless receiver 2 is provided with an interface adapter 3 so as to be rotatable. The mounting angle can be changed freely.
As a result, sufficient transmission performance can be obtained by adjusting the wireless receiver 2 to an optimum angle with high reception sensitivity. However, if the interface adapter 3 of the wireless receiver 2 attached to the electronic device is rotatable, the wireless receiver 2 can rotate wirelessly. There is a problem that the receiver 2 is increased in size and cost.
