Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notebook type portable terminal device such as a notebook type personal computer or an electronic notebook used as a node of a wireless LAN, which is used by opening the lid portion at the time of use. The present invention relates to a structure of a mobile terminal device that can improve antenna performance without enlarging it.

[0002]

2. Description of the Related Art A variety of independent devices (personal computers, terminal devices, word processors, facsimiles, etc.), which are provided in a limited area such as a user's premises or a premises, are interconnected for communication. Network system is a local area network (LA
N).

In such a LAN, for example, in addition to accessing the other terminals in the LAN from the terminal device, the personal computer is accessed to refer to the database held by the personal computer or to connect to the LAN. There is a possibility of various usages such as accessing a device of another LAN via a communication network.

Most of the connections between the respective devices in the LAN are made by wire communication paths, but some of them are formed by wireless communication paths. A configuration in which most of the communication paths are connected by wireless communication paths is also called a wireless LAN.

In a wireless LAN, it is not necessary to mechanically connect a terminal device or the like to a LAN communication network, and if it is registered, it can be used anywhere within the range of radio waves, which is very useful. Is.

In particular, an ultra-compact terminal device formed in a notebook form so that it can be carried at all times is connected to a LAN via a wireless communication path, has high mobility, and can be used for various purposes. .

9A and 9B are views showing a first example of a conventional portable terminal device used for the above-mentioned purpose. FIG. 9A is a perspective view and FIG. 9B is a side view. In the figure,
Reference numeral 30 is a radiation beam of an antenna, 31 is an antenna (in this example, a monopole antenna is shown), 32 is a housing of a mobile terminal, 33 is a keyboard, 3
Reference numeral 4 represents a display, and 35 represents a lid of the housing.

The portable terminal device as described above is used in a state as shown in FIGS. 1A and 1B when it is used. When carrying the portable terminal device, the lid portion 35 is combined with the housing 32. As described above, the antenna 31 is folded along the casing of the mobile terminal device.

LA using a wireless line
When a mobile terminal device is used as the N terminal device, the mobile terminal device is often configured to function as a LAN terminal device via a radio base station incorporated as a LAN node.

Therefore, it is necessary for the antenna of the terminal device to use its beam by directing its beam toward the radio base station. On the other hand, since the portable wireless terminal device is expected to be used in various ways, it is necessary that the beam direction of its antenna can be directed in any desired direction.

In the conventional portable terminal device as shown in FIG. 9, since the monopole antenna 31 can obtain a horizontal beam as indicated by numeral 30, the directional characteristics of the antenna satisfy the condition sufficiently required. be able to.

However, when carrying this, the antenna 31 is folded and the portable terminal device is put in a pocket or bag of clothes. At this time, the antenna is present as a protrusion on the side surface of the housing. Therefore, there is a problem that it is an obstacle and is easily damaged.

As a method for solving such a problem, it is conceivable to adopt a structure in which the antenna is housed in a housing. However, since the thickness dimension of the housing is originally very thin, such a structure is adopted. It was impossible.

FIG. 10 is a diagram showing a second example of a conventional portable terminal device, and is a side view of the portable terminal device.
In the figure, reference numerals 32 to 35 are the same as those in FIG. 9, 41 is an antenna, and 30a is a desired antenna beam direction.

In this example, unlike the first example of the conventional portable terminal device described above, a patch antenna or a phased array antenna as the antenna 41 is used as the housing cover 3.
It is laid on the outer surface of No. 5. When such a structure is adopted, there is no protrusion on the housing of the mobile terminal device, so that there is no inconvenience in carrying.

However, in use, due to its structure,
Beams pointing upwards are difficult to obtain, and the numeral 30
Since the antenna beam as shown by a cannot be obtained, the relative positional relationship between the mobile terminal device and the wireless base station is restricted, which causes a problem in that handling is inconvenient.

As such an example, for example, when a base station is placed near the ceiling in a place such as an auditorium and a user of a portable terminal device turns his back on the base station for use. Can be considered.

FIG. 11 is a diagram showing a third example of a conventional portable terminal device, (a) is a perspective view and (b) is a side view. In the figure, numeral symbols 32 to 35 are the same as those in the case of FIG. 9 described above, and 36 is an input pen and 3
Reference numeral 7 represents a portable wireless device, and 38 represents an antenna. In this example, the portable wireless device 37 is connected to the portable terminal device so that the portable terminal device has a wireless communication function.

In such a structure, since the portable terminal device and the portable wireless device are separated from each other, there is a problem in that the convenience of carrying the portable wireless device is insufficient, and the portable wireless device is erected due to the structure of the portable wireless device. However, since it is difficult to use a beam switching type antenna, it is impossible to direct the beam in a desired direction.

The present invention has been made in order to solve such a conventional problem, and can direct a beam of an antenna in a desired direction without increasing the size and weight of a conventional portable terminal device. It is an object of the present invention to realize a portable terminal device that can be used.
