Abstract

PURPOSE: A slide-type mobile communication terminal is provided to control an operation of a cover such that the cover can be automatically located at fully opened or fully closed area even though a user does not push the cover, thereby fully opening and closing the cover by slightly touching the cover only. CONSTITUTION: A cover(200) is combined with an upper section of a body(100) to slide down in the length direction of the body(100). An opening/closing sensor(500) senses whether an external force for opening/closing the cover(200) is applied, and generates an operational signal. An opening unit opens the cover(200) if the external force is applied in a direction that the cover(200) is opened, and closes the cover(200) if the force is applied in a direction that the cover(200) is closed. A controller receives the operational signal, and drives the opening/closing unit.

Description

Slide type mobile communication terminal {Mobile communication terminal of slide type}

The present invention relates to a slide-type mobile communication terminal, and more particularly, to a slide-type mobile communication terminal for driving a cover coupled to the top surface of the main body so as to be automatically positioned at the maximum opening point or the complete closing point.

As mobile communication terminals become more and more popular all over the world, terminals with various functions and designs are being released to meet users' needs. The terminals have been developed from a general bar type terminal to a flip type terminal, a flip-up type terminal, a folder type terminal, and the like, and recently, a folder type terminal. Is mainstream. This is because the folder type terminal has enough space to adopt the wide LCD module as the display device, and because it is folded in half and portable, the portability is superior to other terminals.

Meanwhile, a type of terminal capable of providing a wide LCD module having a size similar to that of the folder type terminal described above and contributing to miniaturization of the terminal has been introduced. This is a sliding type terminal of a type in which the cover is slid by a predetermined length in the longitudinal direction of the terminal on a predetermined body, and has an advantage that it can meet various user's changing preferences compared to the existing folder type terminal.

When the sliding type terminal is viewed based on the main body, the sliding body may be configured in a state in which the sliding body is opened by sliding downward or upward to about 1/2 of the main body length (this is 1/2 for the operational stability of the terminal). Limited, but may be open more), generally 3 × 4 keypad assembly can be installed on the cover, and the display device can be installed on the front of the main body.

The above-described lid may be guided by a predetermined guide means on the main body, generally forming guide ribs on the lid or main body, and forming guide slit in a portion corresponding to the guide rib of the rest of the lid or main body. The sliding operation is achieved. In addition, a predetermined stopper means is provided or formed at a portion where the lid is slid to open completely or completely closed to prevent the cover from flowing arbitrarily on the main body.

However, the sliding type terminal having the guide means or the stopper means as described above can be fixed in position only when the cover is completely open or closed on the main body.

Therefore, since the cover is arbitrarily flowed during the opening or closing operation, a malfunction of the terminal that is not desired by the user may be caused. In addition, when the cover is to be opened or closed, there is a problem that the cover must be pushed all the way until the cover is caught by the stopper and fixed.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a slide-type mobile communication terminal which controls the operation of the cover so that the cover is automatically positioned at a fully open or fully closed point even if the user does not push the cover. have.
