Next, the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view showing an embodiment of the present invention.

As shown in FIG. 1, the portable information radio communication terminal 1 has a lid 10 that covers a display surface and an operation unit.

FIG. 2 is a block diagram of the portable information wireless communication terminal 1 shown in FIG.

In FIG. 2, a portable information wireless communication terminal 1
Is a lid open / close detector 8, which detects whether the lid 10 has been opened / closed at a predetermined angle, a lid open / close control unit 4, a motor 5, a gear 6, a gear 7, an antenna 9, and a tilt of the portable information wireless communication terminal 1. And an angle controller 2 for controlling the angle of the antenna 9.

Next, the operation of the present invention will be described.

The wireless terminal 1 starts receiving a downlink signal from a base station (relay station) from the time when a power supply (not shown) is turned on.

After the power is turned on, the lid 10 of the wireless terminal 1 is
Is manually opened, the lid open / close detector 8 mounted on the lid 10 moves in conjunction with the opening / closing of the lid, and the opening / closing angle of the lid becomes a predetermined angle, preferably 90 degrees or more ( The lid open / close detector 8 determines that the lid is open , and sends an antenna deployment signal to the angle control unit 2 via the lid open / close control unit 4 (see FIG. 3).

The angle controller 2 controls the motor 5 based on the antenna deployment signal, rotates the gears 6 and 7 by the power of the motor, and automatically deploys the antenna 9 linked to the gear to 90 degrees (see FIG. 4). .

On the other hand, the opening and closing angle between the lid 10 and the main body 1 is 90
If it is less than 90 degrees (see FIG. 5), the operation range of the lid open / close detector 8 is also less than 90 degrees, and the lid 9 cannot be detected by the lid open / close control unit 4, so that the antenna 9 is not deployed and remains housed in the wireless terminal.

FIG. 6 shows a state in which the terminal 1 is used with the antenna 9 opened 360 degrees.

FIG. 7 shows the configuration of the motor 5 for moving the antenna 9 and the gears 6 and 7.

Next, detection of the terminal inclination and adjustment of the antenna angle will be described.

When the wireless terminal is tilted from 0 ° to ± 90 ° with respect to the horizontal axis as shown in FIG. 8 or to the + side as shown in FIG. Is detected by the angle control unit 2 based on the terminal inclination angle signal, the number of rotations of the gears 6 and 7 is determined, and the motor 5 is controlled. The linked antenna 9 is always kept vertically. However, the operation is performed in a state where the lid 10 is opened by 90 degrees or more by the lid opening / closing control unit 4. In addition, the inclination angle and the rotation angle
Relationships are set in advance.

As described above, the antenna angle is adjusted so as to obtain the optimum receiving sensitivity in accordance with the inclination angle of the terminal 1, preferably the display surface or the operation surface thereof.

A preferred configuration and operation of the lid open / close detector 8 shown in FIG. 2 will be described with reference to FIG.

A disk 11 with a hole is fixedly connected to a support rod 14, and the light emitting diode 1 is
2 and the light receiving diode 13 are installed. This part is housed inside the wireless terminal body.

When the lid is opened by 90 degrees or more, the infrared light transmitted from the light emitting diode 12 and the light receiving diode 13 passes through the hole of the disk 11 and is received by the light receiving diode 13. Recognizes that the lid is opened 90 degrees or more.

The structure and operation of a preferred example of the tilt detector 3 shown in FIG. 2 will be described with reference to FIG.

In FIG. 11, the disk 14 is
A weight 15 is attached to the portable information wireless terminal 1 by a foot 16 and a shock absorber 17.

The shock absorber 17 is installed so that the shaft 20 does not vibrate violently due to the weight 15 and cannot be recognized by the light receiving diode.

The tilt detector 3 keeps the shaft 20 and the disk 16 in the same state by gravity due to the weight 15 when the main body of the wireless terminal tilts.

Since the holes pass between the light emitting diode 18 and the light receiving diode 19 sandwiching the disk 14 according to the inclination, the holes are counted one by one and the holes are counted one by one.
Each time the antenna 9 is counted, the antenna 9 is tilted, for example, 10 degrees.

A method for storing the antenna 9 manually or automatically will be described with reference to FIG.

When the opening / closing angle between the wireless terminal and the lid drops from 90 degrees or more to 90 degrees or less, the lid opening / closing detector 8
Then, a "lid closing signal" is sent to the lid opening / closing controller 4.

The lid opening / closing control section 4 sends an "antenna close signal" to the angle control section 2, which controls the motor 5 and automatically stores the antenna 9 linked to the gear in the power in the wireless terminal. I do.

[0033]

As described above, according to the present invention, an optimum receiving sensitivity can be obtained regardless of the inclination of the radio terminal.
