ABSTRACT:
TECHNICAL FIELD
The present invention relates to an information processing apparatus which has a display unit foldable against a main body.
BACKGROUND ART
There have recently been offered as commercial products a large number of portable information processing apparatuses such as notebook personal computers and mobile computers. Such an information processing apparatus consists of a main unit and a display unit, and the display unit can be closed and opened against/from the main unit with a hingeable means. Such an information processing apparatus is recently equipped with an antenna and the like so that data can be exchanged between information processing apparatuses.
FIG. 47
is a perspective view showing a conventional information processing apparatus in which a display unit is opened from a main unit of this computer which is equipped with an antenna.
This computer
400
consists of a main unit
410
having a metallic panel and a display unit
420
having a metallic panel which can be folded and opened against/from the main unit
410
. An antenna
430
is rotatably disposed on a side surface of the main unit
410
. Such the antenna
430
is rotated so as to be erected from the main unit
410
as shown in the drawing when the antenna
430
is to be used, while the antenna
430
is rotated to be nearly in parallel with the main unit
410
when the antenna
430
is not to be used.
In the above described conventional computer
400
in which the metallic panel produces an adverse influence on the antenna, the If antenna
430
is disposed so as to protrude from a side surface of A the main unit
410
. Accordingly, the antenna
430
causes a problem that articles are liable to be caught by the antenna
430
, whereby the antenna
430
or others may be broken. Furthermore, the antenna
430
has a defect that it may not match the main unit
410
and the like in design.
FIG. 48
is a perspective view showing another conventional information processing apparatus in which a display unit is open from a main unit of this computer having an antenna and the like.
This computer
500
has a display unit
520
which is attached to a main unit
510
so as to be capable of freely opening and closing. An antenna
530
is built inside a side surface of the main unit
510
.
Such a computer
500
is capable of solving the above described problems, but since radio waves coming from the left and the front as seen from a user pass through inside the main unit
510
and then attain to the antenna
530
, the computer
500
causes a problem that radio waves are troubled by built-in electronic parts in their courses, thereby lowering a sensitivity of the antenna
530
.
DESCRIPTION OF THE INVENTION
The present invention therefore has an object to solve the above described problems and provide an information processing apparatus which is equipped with an antenna having a high sensitivity.
The present invention accomplishes the above described object by equipping an information processing apparatus with a display unit having a display panel of which rear side is covered with a metallic panel, an antenna member which is disposed in a notch formed in part of the above described metallic panel and a cover in of a non-metallic member which is disposed in the above described notch so as to cover the above described antenna member.
The above described configuration in which the antenna is disposed in the notch formed in the metallic panel allows radio waves to be securely received by the antenna or transmitted from the antenna without being intercepted by the metallic panel. Accordingly, the configuration makes it possible to always receive and transmit accurate data and the like securely and rapidly.
