Conventional example 3. As another conventional example which solves the same purpose by storing the antenna so that it can be taken in and out, there is an "antenna mounting structure" disclosed in JP-A-8-87347.

Conventional example 4. Further, as an example of mounting a wireless transmitting / receiving antenna on a lid of an information processing apparatus to realize a compact antenna apparatus, there is an “antenna apparatus” disclosed in Japanese Patent Application Laid-Open No. 8-78931.

Conventional example 5. As a conventional example in which an antenna member is provided on a lid and reception performance is satisfied in accordance with a use state by opening and closing of the lid, there is a "wireless receiver" disclosed in Japanese Patent Laid-Open No. Hei 6-291687.

[0007] All of the above-mentioned conventional examples 1 to 5 are provided with a transmission / reception function added to the information processing apparatus, and employ a structure for obtaining a predetermined reception (transmission / reception) performance. Among these conventional examples, there is an example in which an antenna is attached to a lid of the device. In the “antenna device” of Conventional Example 4, an antenna is attached to the surface (computer lid) of a device case made of a dielectric material, thereby realizing a compact antenna device. Further, the “wireless receiver” of Conventional Example 5 has an antenna member that is electrically connected to the case body and the lid body, thereby increasing the thickness and shape of the product.
The reception performance is satisfied according to the usage state by opening and closing the lid. Further, in the “information device having an extension unit and the extension slot mechanism” of Conventional Example 2, an extension slot for mounting an extension card with an antenna is attached to a lid (device cover). Further, the expansion slot has a moving mechanism. With this moving mechanism, the expansion card with the antenna moves from inside the device cover to outside during use. Thus, the antenna is arranged at a position distant from the information device main body, and can reliably transmit and receive electromagnetic waves transmitted through the space. In addition, two arrangement examples are shown in order to allow the display unit and the expansion slot to coexist on the lid.

Hereinafter, a part of paragraphs “0033” to “0034” of the specification will be cited from JP-A-7-234744. In the above embodiment, the expansion slot 3 is attached to the back side of the device cover 2 and is arranged at a position not facing the display 2a. As a result, the expansion slot 3 and the display 2a do not overlap in the thickness direction.
Can be made thinner. Therefore, when the present invention is applied to a portable information device which is required to be particularly thin, the effect is large.
On the other hand, a structure may be employed in which the expansion slot 3 is attached to the back surface of the device cover 2 at a position facing the display 2a. In this structure, since the expansion slot 3 and the display 2a overlap in the thickness direction, the thickness of the cover body 2b of the device cover 2 increases. However, the size (area) of the display 2a attached to the front side of the device cover 2 can be increased. Therefore, it is possible to realize an information device having the large-screen display 2a.

As described above, the coexistence of the display unit and the expansion slot having the antenna affects the size of the display unit, and also affects the thickness of the lid of the device and the size of the entire device. Is also having an effect. In addition, none of these conventional examples 1 to 5 describes communication using voice.
