Description

The present invention relates to a foldable portable wireless communication device.
In particular, at least a part of the cover portion that covers the hinge portion that rotatably connects the first housing having the transmitting portion and / or the operating portion and the second housing having the receiving portion and / or the display portion is provided. The case member constituting the first casing and the case member constituting the second casing are configured as separate parts independent of each other, and the cover member configured as the separate part is attached to any of the case members. The present invention also relates to a foldable portable wireless communication device in which an antenna is incorporated in either a first housing or a second housing.

Mobile phones are widely used as portable wireless communication devices. In recent years, foldable mobile phones that have a large display screen and are convenient for carrying have become mainstream.
Also, with recent foldable mobile phones, due to the diversification of design, the main body side case and the display side case can be color-coded (the main body side case and the display side case have different colors). In the main body side housing and the display side housing, the front surface and the back surface of the housing (case) are color-coded. And in order to improve the appearance of the hinge part in that case, it is also performed that the cover of a hinge part is comprised with a member different from the case main body which comprises a housing | casing (for example, refer patent document 1 and patent document 2). ).

Also, recent mobile phones have been developed that have a built-in antenna even in a foldable type.
In a foldable mobile phone, particularly a foldable mobile phone in which a connector for an external interface is provided on the lower end side of the operation side unit, an antenna is built in the upper end side (hinge portion side) of the operation side unit.
