Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal such as a mobile phone and a personal digital assistant, and more particularly to a mobile terminal in which a first housing and a second housing are foldable.

[0002]

2. Description of the Related Art In recent years, foldable mobile phones have become popular. This type of mobile phone includes, for example, as shown in FIG. 14, a first housing 1 in which a receiving speaker 11 and a display 11 are provided, and a second housing 21 in which a transmitting microphone 21 and a keypad 22 are provided. The housing 2 and the housing 2 are rotatably connected via a hinge 3. This type of mobile phone has an advantage that good housing can be obtained by folding and downsizing the housing during standby, and high operability and visibility can be secured by unfolding the housing during communication.

[0003]

By the way, in recent years, many mobile phones have a mail transmitting / receiving function and a web browsing function in addition to the call function. When displaying the information downloaded from the sent / received mail or the web,
It is preferable to display the display information in a landscape orientation from the viewpoint of visibility.
However, since the display provided on the mobile phone is generally vertically long, it is not suitable for horizontally long display. Therefore, for example, as shown in FIG. 14, it has been proposed to use the display 12 in a horizontally long shape so that display data can be displayed. However, in this case, the visibility is improved, but the keypad 22 is also turned sideways, which makes it difficult to create an outgoing mail.

The present invention has been made in view of the above circumstances, and a first object thereof is to provide a foldable portable terminal capable of horizontally displaying display data without impairing operability.

A second object is a foldable type in which the display data can be displayed in a landscape orientation without impairing the operability and the positional relationship between the display section and the operation section can be changed according to the user's application. It is to provide a mobile terminal.

[0006]

In order to achieve the above-mentioned first object, a first invention is a second housing having a first casing having a display portion on the front surface and an operation portion on the front surface. The housing and the housing are rotatably connected to each other via a hinge, and the positional relationship between the housings when the front portions are opened is V-shaped. Specifically, it is realized by forming the connection ends of the first and second housings obliquely with respect to the side surface of the housings and connecting the connection ends formed obliquely with a hinge.

Therefore, according to the present invention, the shapes of the first housing and the second housing are bent in a V shape when the front surface portions thereof are opened. Therefore, as viewed from the user, it is possible to arrange the operation unit of the second housing in a vertically long state in a state in which the display unit of the first housing is arranged in a horizontally long position, which does not impair operability. Horizontal display of display data can be realized.

In order to achieve the above second object, a second
Of the invention, a first connection portion for rotatably connecting a first housing having a display portion on the front surface and a second housing having an operation portion on the front surface using a hinge, The first casing and the second
And a second connecting portion that connects the housing of FIG. 1 to the housing so as to be rotatable about a direction orthogonal to the front surface of the housing.

Specifically, a connecting member for connecting the second connecting portion to the first or second casing via the first connecting portion, the connecting member and the second or the second connecting portion. The first housing is composed of a rotating mechanism that connects the first housing so as to be rotatable about a direction orthogonal to the front surface thereof.

A third aspect of the present invention is a third aspect for rotatably connecting a first casing having a display portion on the front surface and a second casing having an operation portion on the front surface using a hinge. The first connecting portion and the first and second housings connected by the first connecting portion are bent or bent so that the positional relationship between the housings is V-shaped when the front surface is open. And a second connecting portion for connecting in a bendable manner.

Therefore, according to the second and third inventions,
With the front faces of the first casing and the second casing opened, the first casing and the second casing can be arbitrarily rotated by the user by the rotating mechanism or the second connecting portion. It is possible to use it by bending it into a V shape at the angle. Therefore, similarly to the above-described first invention, it is possible to vertically arrange the operation unit of the second housing in a state where the display unit of the first housing is horizontally arranged as viewed from the user. As a result, the horizontally long display of the display data can be realized without impairing the operability.

Moreover, in the first and second inventions, since the bending angle between the first casing and the second casing can be changed by the second connecting portion, the display portion and the operating portion can be The orientation can be set to the optimum state desired by the user.

In the second and third aspects of the invention, the angle detecting means detects the rotation angle or bending / bending angle between the first casing and the second casing by the second connecting portion. It is also characterized by further having a function of switching and controlling the display direction of the display information on the display unit according to the detection result of the angle detecting means.

With this configuration, for example, when the user bends the angle between the first housing and the second housing by a predetermined angle or more, the display direction of the display information on the display unit is directly facing the user. It can be switched automatically. For this reason, the user does not need to separately perform an operation for switching the display direction of the display information, which can simplify the operation labor.
