MOBILE TERMINAL HAVING MOUSE DEVICE}

The present invention relates to a mobile terminal with a mouse function, and more specifically, to the back of a mobile terminal such as a general personal mobile phone or a personal digital assistant (PDA), an optical sensor for detecting a moving state using a reflection amount of light is provided. A button unit selected by pressing by the finger on the front side of the mobile terminal by positioning the terminal to a predetermined range while the back of the terminal on the floor by controlling the movement of the cursor displayed on the LCD screen of the mobile terminal menu through the cursor The present invention relates to a mobile terminal having a mouse function that enables a user to easily select, move and switch a liquid crystal screen.

In recent years, computers and mobile phones have become a necessity of personal life. This is a phenomenon caused by combining information such as computer and mobile phones that can be easily used by users and information needs of modern people.

BACKGROUND ART As a peripheral device for an individual user to easily use such information as the Internet, a mouse that enables a user to easily perform various menu selections and screen switching on the display is widely used.

Such a mouse is a peripheral device which indicates its position by using a cursor displayed on a display device of a computer. Among these mice, an optical mouse using an optical sensor, in particular, reflects light emitted from a light emitting diode mounted inside the mouse body. Use to detect the amount of movement of the X and Y axes of the mouse.

That is, after the light emitted from the light emitting diode is reflected by the pad, the light reflected by the pad is collected by a lens mounted inside the mouse and reflected by the mirror to be received by the optical sensor. As described above, the optical sensor that receives light detects the amount of movement of the mouse's X axis and the Y axis through the change in the amount of received light, and outputs a signal. To move in the axial direction.

On the other hand, in recent years, users of mobile phones, which are cordless phones rather than wired phones, are increasing day by day, and now mobile phones can easily enjoy wireless Internet, games, chats, etc., as described above, in addition to simply communicating with others. Regardless of age and gender, the population of people is exploding.

Accordingly, due to the development of the Internet, not only a method of obtaining information using a fixed computer, but also wireless Internet based on wireless LAN technology is available in most mobile devices such as personal mobile devices such as mobile phones or PDAs. There is an active discussion on how to use it.

However, these general mobile terminals still have a lot of vulnerabilities for users to enjoy such Internet browsing or games, one of them, the user to make various menu selection and screen switching on the screen appearing on the liquid crystal display of the mobile terminal In order to limit the user input method, the above-described menu selection and screen switching are performed through a complicated process compared to a general computer, which is a significant problem.

The present invention has been made to solve the above problems, the object of the general mobile terminal has a button portion that is selected by pressing a finger to the front of the built-in optical sensor for detecting the movement state using the amount of light reflection By controlling the movement of the cursor displayed on the LCD screen of the mobile terminal by moving the terminal to a predetermined range while the user places the back of the terminal on the floor, the user selects the menu through the cursor and moves and switches the LCD screen. The present invention relates to a mobile terminal having a mouse function, which facilitates the use of the Internet through a mobile terminal, and can be easily used for a game for a mobile terminal.
