[0001] MOBILE TERMINAL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a mobile terminal having a drawer structure of a tray on which chips and the like are placed.

A terminal can be divided into a mobile terminal (mobile / portable terminal) and a stationary terminal according to whether the terminal can be moved. The mobile terminal can be divided into a handheld terminal and a vehicle mount terminal according to whether the user can directly carry the mobile terminal.

Such a terminal has various functions, for example, in the form of a multimedia device having multiple functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game and broadcasting, etc. .

In order to support and enhance the functionality of such terminals, it may be considered to improve the structural and / or software parts of the terminal.

On the other hand, in a mobile terminal, in particular, a uni-body type mobile terminal, a structure in which a separate pin is required for pulling out a tray on which a USIM, an SD card or the like is placed from the terminal is adopted.

However, such a tray pull-out structure is difficult to perform its function when there is no pin for pulling out the tray, and it may act as a factor for hindering aesthetic elements of the mobile terminal as the structure of the hole for inserting pins is exposed to the outside of the terminal .

Therefore, in implementing the tray structure of the mobile terminal, other tray pullout structures other than the structure using the pins can be considered.

It is an object of the present invention to provide a mobile terminal having a tray pull-out structure other than a tray pull-out structure using a pin.

According to another embodiment of the present invention, the tray includes a first seating portion on which a first chip storing first information is seated, and a second seating portion disposed adjacent to the first seating portion, And a second seating portion on which a second chip for storing information is seated.

According to another embodiment of the present invention, the magnetic portion suppresses the elastic force of the spring portion that presses one region of the tray so that the tray is positioned inside the terminal using the magnetism, The elastic force of the spring portion may be released so as to be pulled out of the terminal body.

Wherein the magnetic portion includes a magnet that exhibits magnetism regardless of whether a current is applied or not and an electromagnet that exhibits magnetism upon application of an electric current, wherein the magnetic portion is configured to change a magnetic field of the magnet in a first state in which no current is applied to the electromagnet the magnetic force of the magnetic field is suppressed by suppressing the elastic force of the spring portion which presses one region of the tray by a magnetic force and a magnetic flux which is formed in a direction opposite to the magnetism of the magnet in a second state, The magnetic force of the magnet may be canceled to release the state in which the elastic force of the spring portion is suppressed.

Wherein the electromagnet includes a core portion made of a conductive material and a coil portion made of a conductive material and wound around the core portion in one direction and the magnet is arranged to provide a magnetic force for coupling with the tray through the core portion, And may be formed to be electrically connected to the core portion.

The magnetic part is configured such that both sides thereof are tilted with respect to the rotation axis and are provided with elastic forces which are formed in different directions from the spring part, And an auxiliary member connected to the core portion to be electrically coupled to the core portion in the first state or to be disengaged from the core portion in the second state can do.

Wherein the spring portion includes a first spring disposed on one side of the auxiliary member and providing an elastic force in a direction to press one region of the tray and a second spring disposed on the other side of the auxiliary member, The elastic force of the first spring is suppressed by the electrical coupling between the other side of the auxiliary member and the core portion in the first state, The state where the elastic force of the first spring is suppressed is released as the electrical coupling between the other side of the auxiliary member and the core part is released.

According to the mobile terminal of the present invention, the tray, on which at least one chip is mounted on one surface, is pressed by the spring portion according to a condition that a current is applied to the magnetic portion, And is drawn out of the terminal body or positioned inside the terminal body. Accordingly, the present invention does not require a separate member for pulling out the tray, so that the convenience of the user can be further improved and the tray area exposed to the outside of the mobile terminal while the tray is located inside the terminal body can be beautifully realized.
