In the main body 100, a keypad 102 for controlling various functions is installed on a surface thereof, and a control circuit unit is built therein, and the display device 150 is equipped with a liquid crystal screen 152 that receives a signal from the control circuit unit and outputs an image. do.

The sub body 140 has a through part 142 for passing the rotating plate 130, and a mounting space 144 through which the display device 150 can rotate is formed.

The fixing plate 110 is connected to the main body 100, the slide plate 120 to the sub body 140, and the rotating plate 130 to the display device 150 by fastening means such as a screw.

A slide shaft 122 is fixed to the slide plate 120, and a shaft holder 112 is slidably coupled to the slide shaft 122 at the fixing plate 110. The slide shaft 122 is made of a metal material and subjected to precise processing to obtain a beautiful surface.

When the slide plate 120 is close to the position where the slide plate 120 is closed based on a predetermined point in the movement path of the slide plate 120, an elastic force is applied to the slide plate 120 in the closing direction, and when the slide plate 120 is close to the open position. The first elastic member is installed to apply an elastic force to the slide plate 120 in the opening direction.

The first elastic member includes a torsion spring 160 having one end supported by the fixed plate 110 and the other end supported by the rotating plate 130.

The torsion spring 160 applies an elastic force to maintain the initial state on the rotating plate 130 in a state in which the rotating plate 130 is not rotated, and rotates to the rotating plate 130 in a state in which the rotating plate 130 is rotated. Apply an elastic force to maintain the state.

And the winding portion of the torsion spring 150 is wound many times so that the radius gradually expands on the concentric circle. Accordingly, by minimizing the height value of the torsion spring 160 irrespective of the number of turns of the torsion spring 160, the constraint on the terminal design may be reduced by excluding the restriction on the size and thickness of the terminal.

In addition, the inflection point in the elastic force direction of the torsion spring 150, so that the fixing plate 110 is located within 1/2 of the total travel distance from the closed point. That is, by shortening the distance to the inflection point in the operation of opening the sub body 140, it is possible to quickly open the sub body 140 when the beep sound from the main body 100.

The operation of the present embodiment will be described below.

5 is a plan view of a state of use of the communication terminal shown in FIG. 4, and FIG. 6 is a cross-sectional view of FIG.

In a state in which the communication terminal is closed, the sub body 140 overlaps the main body 100 where the keypad 102 is installed and is closed. At this time, the slide plate 120 coupled to the sub body 140 receives the elastic force of the torsion spring 160 to maintain the closed state.

In addition, the rotating plate 130 to which the display device 150 is coupled maintains its initial state by receiving the elastic force of the torsion spring 160.

In this state, when the sub body 140 is pushed by hand to open the communication terminal, the sub body 140 and the slide plate 120 slide together. At this time, the slide shaft 122 fixed to the slide plate 120 slides in the shaft holder 112 of the fixing plate 110.

At first, a force must be applied to push the sub-body 140, but when the inflection point of the torsion spring 160 is passed, the slide plate 120 is pushed in the opening direction by the elastic force of the torsion spring 160. From this time, even if no force is applied to the sub-body 140, it automatically moves to the open position.

Even when the sub body 140 is completely open, the elastic force of the torsion spring 160 is continuously applied to the slide plate 120, thereby maintaining the open state of the sub body 140.

When the sub body 140 is opened, since the keypad 102 of the main body 100 is opened, the user can use a unique function of the communication terminal.

On the other hand, when you want to watch a movie through the LCD screen 152 of the display device 150 in a state in which the sub body 140 is off, the display device 150 is rotated by 90 ° by hand.

Then, the rotating plate 130 coupled to the display device 150 rotates about the central axis 136, and after the display device 150 is rotated 90 °, the rotation limiting protrusion 128 is the trajectory groove 132. The rotation of the display device 150 is restricted by the end of the display panel 150. Thereafter, the torsion spring 160 continuously pushes the rotation plate 130 in the rotational direction, thereby maintaining the rotated state of the display apparatus 150.

As such, when the display device 150 is rotated by 90 °, the liquid crystal display 152 mounted on the display device 150 is elongated in the horizontal direction, thereby making it suitable for watching a movie. Therefore, the user can see the screen of the normal movie through the LCD screen 152.

On the other hand, after watching a movie through the LCD screen 152, the display device 150 is rotated in the reverse direction. Accordingly, the rotating plate 130 rotates in the reverse direction about the central axis 136. After the display device 150 is rotated 90 °, the rotation limiting protrusion 128 is caught by the end of the trajectory groove 132. The rotation of the display device 150 is limited. Thereafter, the torsion spring 160 continuously pushes the rotation plate 130 to an initial position, thereby maintaining the initial state of the display apparatus 150.

On the other hand, to close the communication terminal in a state in which the sub body 140 is open, the user pushes the sub body 140 in the direction of closing by hand. The closing operation of the sub body 140 is performed in the reverse order of the opening operation.

As described above, the present invention is a slide and rotation type communication terminal capable of opening and closing the sub body in a slide manner and rotating the display device installed in the sub body so that the horizontal direction becomes long. It is effective to display long images in the horizontal direction.

The present invention has been described above as a specific embodiment, but the present invention is not limited to the above-described embodiment, and those skilled in the art without departing from the gist of the present invention claimed in the claims. Anyone can make a variety of variations.
