Description

Mobile terminal with rotatable folder {MOBILE COMMUNICATION TERMINAL WITH ROTATABLE FOLDER}

The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal having a rotatable folder.

Currently, the mobile communication terminal is converting to a structure capable of transmitting high speed data in addition to the voice communication function. That is, by implementing a mobile communication network of the IMT 2000 standard, it is possible to implement high-speed data communication in addition to voice communication using the portable terminal. Data that can be processed by the mobile communication terminal performing the data communication may be packet data and image data. In addition, a function of displaying a video signal by adding a camera or a TV receiver to a mobile communication terminal is implemented. Therefore, the mobile communication terminal having a camera as described above can take a picture of the video and display it as a moving picture and a still picture, and can also transmit the captured picture.

However, in the above mobile communication terminal, the display of the video signal is always displayed in a fixed state regardless of the direction in which the mobile communication terminal is located. That is, when the user views the display screen of the mobile communication terminal, the user can always see only the screen in the fixed position. Therefore, when the user of the mobile communication terminal views the screen displayed by rotating the mobile terminal at an angle, there is a problem in that the direction of the user's eyes and the displayed screen do not coincide.

On the other hand, as shown in Figures 1a and 1b, the hinge portion 104 connecting the folder 105 and the main body 101, the LCD 160 mounted on the mobile communication terminal is designed to rotate, the terminal ( 100), the user can check the terminal status information through the LCD 160 at any position. Such a terminal is called a rotation phone.

In the rotation phone, not only the folder 105 but also the camera 140 is designed to rotate so that the user can shoot the camera at any angle. In addition, since the folder 105 is rotated, if the folder is rotated and closed without attaching a separate auxiliary LCD on the outer plate surface of the folder 105, the LCD 160 mounted to the folder 105 is exposed, so that the user can easily The reception state and time of the terminal can be checked.

However, in a mobile communication terminal having no rotation function, when a telephone ringing, a call was opened by opening a folder. However, in the rotation phone 100, when the folder 103 is rotated and overlapped with the main body 101, when the telephone rings, the folder 105 can receive a call only after the folder 105 is rotated to a normal position. This is because when the phone is received while being rotated and closed, the speaker 102 is placed on the microphone 103, that is, the speaker 102 is placed at the same position. Because it is far away because the other party can not hear the call. Therefore, in the state where the user rotates the folder of the rotation phone, the user needs to go through the procedure of opening and rotating the folder as described above in order to make a phone call.

Accordingly, an object of the present invention is to enable a telephone call even when a folder is rotated in a mobile communication terminal having a rotatable folder.

Another object of the present invention is to enable a user to answer a call quickly while the folder is rotated.
