DESCRIPTION OF THE PREFERRED EMBODIMENTS
An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the shape of the D-SUB connector.
[0018]
<Example 1>
It is said that for a wireless device that performs communication using direct waves, if the antenna for the transmitter and the antenna for the receiver are different, the receiving sensitivity is extremely reduced. The value is at least -3 dB, which greatly affects the communication itself. Looking at the mounting position of the connector in the personal computer, as shown in FIG. 1, the mounting direction is different every 90 degrees from the reference position. Among these, the reference position and the direction 180 degrees from the reference position are often used in general, and therefore, in many cases, it is necessary to deal with these two directions.
[0019]

The wireless device main body 210 can have an angle difference with the connection connector 240 within a range of 180 degrees by the rotating hinge 220. The connector 230 uses D-SUB. The angle between the wireless device main body 210 and the connector 240 may be an arbitrary angle, or may be locked at a certain angle.
[0021]
<Example 2>
FIG. 3 shows a wireless device having a USB type connector. The difference from FIG. 2 is that the connector 340 has a USB type connector. The other parts have the same functions as the wireless device 200 shown in FIG.
[0022]
In the wireless devices 200 and 300 shown in FIGS. 2 and 3, the wireless device main body cannot be perpendicular to rotations of 90 degrees and 270 degrees from the reference position shown in FIG. 1. For example, when the connector of the transmitting wireless device is in the direction of the standard position in FIG. 1 and the position of the connector of the receiving wireless device is 90 degrees from the reference position in FIG. The eclectic surface will be 90 degrees different. Therefore, the reception sensitivity is kept very low.
[0023]
<Example 3>

[0027]
<Example 5>
8 and 9 show an example in which a wireless device is connected to a personal computer. Taking the notebook personal computer 800 as an example, the connector is generally arranged on the side surface and the back surface of the main body 810. First, the case where the connector for connecting the wireless device 300 is arranged on the back surface will be described (see FIG. 8). Since the interface of the notebook personal computer 800 is generally of the USB standard, the wireless device 300 shown in FIG. 3 is used. Since the liquid crystal display device 820 is fixed to the main body 810 of the notebook computer 800 with a movable hinge, the user of the personal computer 800 can freely change the angle of the liquid crystal display device 820 to adjust the position to be easily viewed. It can be used. However, when the wireless device 300 is inserted into the connector on the rear surface, and when the position of the wireless device 300 is perpendicular to the connector, the wireless device 300 hits the liquid crystal display device 820, and the use angle of the liquid crystal display device 820 is On the other hand, an angle of 15 degrees from the perpendicular was used as the use angle. Therefore, the angle formed between the connection connector of the wireless device 300 and the wireless device main body 310 is 105 degrees. Since the radio impedance of the wireless device 300 changes when an object is present in the vicinity, which causes a reduction in the radiation efficiency of radio waves, it is necessary to keep the antenna away from the object as much as possible. If the plane of deviation of the radiated radio wave changes, it will cause a significant reduction in the reception efficiency.
[0028]
Next, the case where the connector for connecting the wireless device 300 is arranged on the side will be described. FIG. 9 is a mounting diagram of the wireless device when a connector for connecting the wireless device is arranged on a side surface. In this case, since there is no fear of hitting the liquid crystal display device 820 or the like, the wireless device can be kept perpendicular to the ground by setting the angle between the connector and the wireless device main body 310 to 90 degrees.
