Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in the field of portable telephones and the like, has a structure capable of folding and rotating display means for displaying a transmission / reception state and its information content, and particularly uses a video camera. The present invention relates to a mobile terminal device having an imaging unit.

[0002]

2. Description of the Related Art Conventionally, various types of foldable mobile phones have been known. For example, Japanese Patent Publication No. 5-44217 and Japanese Patent Application Laid-Open No. 7-95651 propose a foldable small-sized mobile phone. ing. Furthermore, in recent years, not only is the display panel surface enlarged to accommodate the communication of characters and image information so that this display surface can be folded, but it can also be rotated by an axis perpendicular to the folding axis to turn the display surface upside down. Japanese Patent Laid-Open No. 2001-298513 makes it possible to use characters and image information even in a folded state by making a structure that can be folded back as it is.
JP 2001-251406 A is known. These are suitable for communicating text and image information by mail or the Internet, and have an excellent handling property.

In order to further improve the convenience of the mobile phone, if it has an image pickup function equipped with a camera, it can be used as a so-called videophone. Examples of the mobile phone having the videophone function are disclosed in JP-A-6-292195 and JP-A-6-292197. This has the effect of enabling the videophone function by using the speakerphone and earphone while shooting the user himself with the camera arranged on the display side.

In such a foldable mobile phone, the folded housing is opened at the time of browsing various kinds of information, or even when the folded mobile phone is in the folded state as shown in these disclosed examples, the display unit on the back side requires the minimum necessary amount. It is possible to browse the information of. However, when the independent display unit is provided, the thickness of the display unit affects the external thickness, and the thickness of the entire set increases. If the layout avoiding the same projection plane as the main display portion is taken into consideration in order to avoid the thickness, the size of the design and the independent display portion is restricted, which causes a problem in usability. Therefore, it is desirable to have one display section. During operation of the operation unit, the image cannot be seen from the front of the user. In addition, it is difficult to operate when you are the subject looking at the display. Further, in this disclosed example, only the user himself / herself is the subject, and other external subjects (for example,
It is difficult to use it for the front view that comes into the user's view.

As another conventional example, Japanese Patent Laid-Open No. 10-65780, in which the image pickup camera portion has a rotating structure, is cited. In this disclosed example, an external subject can be imaged, but since the camera unit is rotated, the camera imaging unit is turned upside down, and the screen of the display unit is also displayed upside down (upside down). Moreover, when the user himself / herself is imaged, the operation of moving the camera unit is required. Further, since the display section and the operation section are on different planes, it is difficult to operate while looking at the display section. Then, the combined operation including the first operation of opening the display housing and the second operation of pointing the camera at the subject is started. This is complicated in operation in the above-described embodiment because the camera starts to be used in the first operation for opening the folded state.

Another embodiment, Japanese Patent Laid-Open No. 2001-3204
Japanese Patent Laid-Open No. 63-63 is a mobile phone in which a camera is arranged on a back surface or a side surface of a housing in which an operation unit is arranged, and a display surface is foldable with respect to the housing of the operation unit. In this example, a structure is adopted in which the display surface is rotated by a folding shaft and a shaft perpendicular to the folding shaft. This structure is capable of projecting not only the user himself but also an external subject that is in the field of view of the user. In this disclosed example, a camera is provided on the back surface or the side surface. When an external subject is imaged, the camera provided on the back surface or the side surface is aimed at the subject,
An image is taken while being monitored by the display means. When the user himself / herself is imaged, there is an effect that the camera disposed on the back surface or the side surface is directed to the user himself, and the display surface is rotated by an axis orthogonal to the axis of folding to monitor and image. .

However, in this example, when the external subject is imaged, it can be imaged by the first operation of opening the display housing, but when the subject is the user, which is the main usage as a videophone. The second operation of turning over the display housing by 180 degrees is required. Moreover, in this conventional configuration, since the image pickup means is fixedly mounted on the back surface or the side surface of the housing, when the user tries to make a videophone call while photographing himself or herself, the key button surface, which is the operation unit, is placed on the back surface or the side surface. It has to be pointed, and it is difficult to operate.
Moreover, in order to capture an image of an external subject while looking at the display unit, it is necessary to open the two housings at the hinge joints and capture the image. This leads to the problem that the advantage of downsizing in the folding method is lost. is there.

By the way, in the use of a mobile phone, not only one original user performs remote communication, but also one user,
It may also be used by a second user who is nearby.
For example, if it is possible to play a game with a game function in which the first main user becomes the subject and the main operation is performed while the second user answers while looking at the display,
The convenience can be further improved.

However, in the case of a method in which the first user uses the operation unit and the imaged subject and the second user uses the display unit, the above-mentioned JP-A-6-29219 is used.
5, JP-A-6-292197, JP-A-10-6578
It cannot be realized with 0, and it is difficult even in Japanese Patent Laid-Open No. 2001-320463.
