The present invention relates to a mobile communication terminal having an auxiliary display unit for allowing a user located in a direction to view the same output image.

In general, a mobile communication terminal refers to a device that transmits and receives voice data to and from a large station by a mobile communication system composed of a base station, a base station control station, and an exchange station. The basic configuration consists of a display that shows selection options through a window, and a battery pack and antenna that are removably attached to the device body.

As the spread of mobile communication terminals has become more common, almost all ages of men and women possess almost all of them, and due to the rapid development of information and communication technology, various additional functions and services are added in addition to the function of simply transmitting and receiving voice, and also the communication speed of data Many types of mobile communication terminals have been released.

For example, FIG. 1 shows an example of a slide type mobile communication terminal in which a folder opening and closing method is modified. As shown in FIG. 1, the upper plate 10 of the terminal moves upward along the lower plate 20 (or vice versa). (20 may be moved downward) to maintain the open state to make the terminal in a callable state, the upper panel 10 is provided with the LCD panel 12, the display window, the lower plate 20 for input The button 22 of the form is provided.

Recently, with the introduction of video communication terminals, a number of services such as video call and video streaming have been used. Accordingly, a larger screen display function has been requested.

In spite of such a request, conventional slide type mobile communication terminals of various types are not provided with an LCD panel having a size corresponding thereto, causing inconvenience in use.

In addition, although a slide type mobile communication terminal equipped with a dual LCD panel has been released, most of them are used as a means of assisting the main LCD panel, so that multiple users can view images output from the terminal in different directions. There is a problem that the function does not provide.

Accordingly, the present invention is to solve the problems in the prior art described above, the mobile communication terminal consisting of the main body and the slide unit is arranged to form the same plane in a straight line after the slide, the connector socket provided in the main body and the slide It is an object of the present invention to provide a mobile communication terminal having an auxiliary display unit that is detachably mounted on both sides of the auxiliary display unit is mounted on both sides through which the two people can play games or watch movies at the same time.

Mounted to be positioned.

When the fixed pin release button is pressed, the fixed pin is removed from the guide rail so that the driving wheel of the roller unit coupled to the main body can move along the guide rail to the guide rail formed on the upper surface of the slide unit. It slides downward from the upper surface of the part to be spread out to form the same surface.

The roller unit includes a driving wheel inserted into the guide rail and a shaft portion coupled to the driving wheel and rotatably coupled to the main body.

The shaft portion may include a first shaft coupled to the driving wheel and a second shaft coupled to the first shaft perpendicularly and both ends coupled to the main body, wherein any one of the first shaft and the second shaft One is rotatably coupled so that the driving wheel can be moved along the guide rail of the upper surface from the front guide rail of the slide portion.

In the above-described configuration, the main body portion slides upward on the slide portion by the roller portion, and then, when the main portion is positioned on the upper surface of the slide portion, the first shaft portion of the roller portion is rotated to slide downward along the guide rail positioned on the upper surface. As a result, the main body portion and the slide portion can be unfolded to be disposed on the same plane.

When the main unit and the slide unit are disposed on the same plane as above, and the auxiliary display unit is combined with the terminal, output images such as movies and game images played by the terminal are output to the auxiliary display unit. The game can be played for two people through the keypad provided in the main body and the slide.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

2 is a perspective view of a mobile communication terminal according to an embodiment of the present invention, Figure 3 is an exploded perspective view of the main body and the slide in the mobile communication terminal of Figure 2, Figure 4 shows a detailed configuration of the roller unit 300 It is a cross section.

As shown in FIG. 2 and FIG. 3, the mobile communication terminal according to an embodiment of the present invention includes a main body 110 and a main body 110 and a slide unit 120 to which the main body 110 is slidably coupled. And the auxiliary display unit 200 mounted on the terminal in a state in which the terminal 100 is unfolded so that the main body 110 slides and is positioned above the slide.

A main connector 113 and a key button are mounted on the front of the main body 110, and a first connector socket 111 to which the first connector 211 of the auxiliary display unit 200 is coupled is formed at the bottom. In addition, at the corner where the lower surface and the rear surface of the main body 110 meet, the roller 300 which guides the main body 110 to slide on the guide rails 122 and 122 'of the slide 120 is provided with a guide rail ( 122, 122 ').

As shown in FIG. 4, the roller part 300 includes a shaft portion to which a driving wheel 311 and a driving wheel 311 are coupled to be inserted and driven in the guide rails 122 and 122 ′. The shaft portion may be composed of a first shaft 312 and a second shaft 313 coupled perpendicularly to the first shaft and both ends coupled to the body portion 110. In this case, the driving wheel 311 is moved along the guide rails 122 of the slide unit 120 and then moved in order to be moved in the guide rails 122 'formed on the upper surface of the slide unit 120. The shaft 312 is rotatably coupled to the second shaft 313, or the second shaft 313 is rotatably coupled to the body portion 110.

In addition, guide parts 122 and 122 ′ extending from the front surface to the upper surface are formed at both sides of the slide part 120. And, the side of the slide portion 120 is equipped with a fixing pin 130 that can be configured as an enlarged view of a portion of Figure 3 restricting the movement of the roller portion 300 on the guide rail 122.

The fixing pin portion 130 extends from the fixing pin release button 131 and the fixing pin release button 131 having the protruding jaw 131 ′ supported by the inner wall of the slide portion, and the end is bent to guide rail 122. The spring is inserted into the fixing pin 132 and the fixing pin 132 positioned on the spring to elastically support the fixing pin release button 131 between the protrusion 131 ′ and the inner wall of the slide unit 130 ( 133, the fixing pin release button 131 protrudes from the side wall of the slide part 120, and the fixing pin 132 is mounted to be positioned inside the guide rail 122.

The fixing pin 132 is removed from the guide rail 122 when the fixing pin release button 131 is pressed, so that the driving wheel 311 of the roller unit 300 coupled to the main body 110 may move the guide rail 122. In this case, the first rail 312 or the second shaft 313 is rotated to guide the guide rail 122 'formed on the upper surface of the slide part. By being rotated 90 degrees on the rail 122 ′, the main body 110 is slid from the upper surface of the slide 120 to form the same surface.
