Problems solved by technology

[0004]However, when the antenna is built into the case, the antenna is usually mounted on the circuit board, but the case part or the circuit module which is the case In the case where metal is used for the reinforcing part of the circuit module and the electromagnetic wave shielding part of the circuit module, since these metals are placed close to the antenna, there is a problem that the transmission and reception characteristics of the antenna deteriorate.

no. 1 Embodiment approach

[0022] 1A to 1C are three views of a mobile phone 1 as an embodiment of a mobile wireless device to which the present invention is applied. Here, FIG. 1A is a side view, FIG. 1B is a front view, and FIG. 1C is a rear view.

[0023] The mobile phone 1 of this embodiment is a folding type. In this cellular phone 1 , an upper case 2 is rotatably connected to a lower case 3 via a hinge portion 4 , and the upper case 2 and the lower case 3 are freely openable and closable to each other via the hinge portion 4 .

[0024] The upper case 2 is composed of a watch case 21 and a back case 22 . Of the front and rear surfaces of the upper case 2 , the front surface (that is, the case 21 side) that is inside when folded is provided with a main display unit 6 composed of a liquid crystal display panel or an electroluminescent display panel. In addition, a speaker 7 for communication is provided in the upper case 2 at a location farther from the hinge portion 4 than the main display portion...

Embodiment approach

[0055] Below, refer to Figure 5 to Figure 11A , B The second embodiment of the present invention will be described.

[0056] Figure 5 It is a perspective view seen from the front side in a state where a foldable cellular phone 101 as an embodiment of a portable wireless device to which the present invention is applied is opened. exist Figure 5 Among them, 102 is an upper case, 103 is a lower case, and 104 is a hinge portion, and the upper case 102 and the lower case 103 are rotatably coupled via the hinge portion 104 .

Abstract

In the portable telephone (1) of the present invention, an upper case (2) is freely connected to a lower case (3) through a hinge (4). A substrate storage recess (37) is formed on the front of the middle case (31) of the lower case (3), and an antenna storage recess (38) is formed on the back. A circuit board (51) is accommodated in the substrate accommodation recess (37), and an antenna (60) is accommodated in the antenna accommodation recess (38). The watch case (32) covers the substrate storage recess (37), and the back case (33) covers the antenna storage recess (38). In addition, the edge portion of the keyboard (53), which doubles as a waterproof seal, is sandwiched between the middle case (31) and the watch case (32) along the edge of the substrate storage recess (37), and the edge of the waterproof seal (65) Partially sandwiched between the middle case (31) and the back case (33) along the edge of the antenna receiving recess (38).

Description

technical field [0001] The present invention relates to portable radios, and more particularly to portable radios with built-in antennas. Background technique [0002] Mobile phones are widely used as portable wireless devices, and some have built-in antennas in their casings. (For example, refer to JP-A-2003-8320 and JP-A-2004-297535). [0003] In addition, in mobile phones, in order to improve the impact resistance of the housing, high specific strength and light weight are used for the shell parts of the housing, especially the watch case parts in which holes for operation buttons and the like are formed. Metals such as magnesium alloys (for example, JP-A-2001-292208 (International Publication WO 01 / 58116A1)). In addition, in the cellular phone described in Japanese Patent Application Laid-Open No. 2001-292208, a metal such as a magnesium alloy is used for a reinforcing member and an electromagnetic wave shielding member of a circuit module. [0004] However, when the ...
