The rotation guide slot 130 is a circle in which the slide member 220 fixed to the main body 200 can be accommodated without disturbing the rotation when the display unit 100 rotates about the rotation center P. It is formed into an arc. The rotation guide slot 130a positioned adjacent to the rotation center P is formed in an arc shape having a radius from the rotation center P to the slide member 220a as a radius, and is located away from the rotation center P. The rotation guide slot 130b is formed in an arc shape having a radius of the distance from the rotation center P to the slide member 220b. The rotation guide slot 130b has an arc shape connecting two sliding guide slots 120a and 120b. The rotary guide slots 130a and 130b communicate with the rotary guide slots 130a and 130b and the sliding guide slots 102a and 120b because the slide member 220b must be moved from the sliding guide slots 120a and 120b. It is. In addition, as shown in FIGS. 3 and 4, the communication port 111 is formed at a part of the side surfaces of the guide rails 110a and 11b for the communication.

Since the rotation guide slot 130 is formed to have a circular arc trajectory based on the distance from the rotation center P to the slide member 220, the slide member 220 rotates when the display unit 100 rotates. It is bound and guided along the arc-shaped shape of the guide slot 130. Therefore, since the display unit 100 naturally constrains the rotation path, the portable mobile communication terminal according to the present invention does not need to have a separate hinge device for rotating the display unit.

On the other hand, as described above, the main body 200 is provided with a mounting groove 230 in which the protruding member 240 is mounted, and the center of the mounting groove 230 is the center of rotation (P) of the display unit 100. Matches. 4 and 5, when the protruding member 240 protrudes, an accommodation groove 140 is formed to accommodate the protruding member 240. 6, when the display unit 100 does not reach the rotational position with respect to the main body 200, as shown in FIG. 6, the protruding member 240 is pressed by the display unit 100 to the inside of the mounting groove 230. Is contracted so as not to interfere with the sliding movement of the display unit 100, when the display unit 100 is moved to a position where the receiving groove 140 and the mounting groove 230 coincide with the receiving groove 140 Is inserted into By doing so, the user can sense that the display unit 100 is slidably moved to the rotational position, and the user can rotate the display unit 100 with respect to the protruding member 240. Since the upper end of the protruding member 240 has a spherical shape, even when the protruding member 240 is slid in the receiving groove 140, the display unit 100 is protruding from the protruding member ( The upper end of the 240 to facilitate the ride.

According to the present invention, when the display unit 100 rotates as described above, a separate hinge device is provided because the slide member 220 fixed to the main body 200 is guided along the circular guide slot 130 formed in the display unit.
