Abstract

Disclosed herein is a portable communication terminal for displaying information that is suitable for use as a personal digital album, and that includes a cover having a planar surface; a display device adapted to open/close via a sliding linear movement along a direction away from the cover, and a rotational movement toward the cover; a number of openings formed on the cover for providing the sliding and rotational movements of the display device and for exposing the information displayed on the display device; and at least one support arm placed on the lateral surface of the cover for supporting the sliding and rotational movements of the display device.

Claims

1. A portable communication terminal for displaying information comprising:

a cover having a planar surface;

a display device adapted to open/close through a sliding linear movement in a direction away from the cover and a rotational movement toward the cover;

a plurality of openings formed on the cover to facilitate the sliding and rotational movements of the display device and to expose the information displayed on the display device; and

at least one support arm placed on a lateral surface of the cover for supporting the sliding and rotational movements of the display device.

2. The portable communication terminal for displaying information as claimed in claim 1, wherein the cover is provided with a positioning means for selectively supporting said terminal at a slant in a transverse or longitudinal direction.

3. The portable communication terminal for displaying information as claimed in claim 2, wherein the positioning means includes a receiving groove formed on a bottom surface of the cover and a positioning rod having an end insertable into the receiving groove to perform a sliding movement along the receiving groove, the positioning rod being adapted to be rotated vertically and horizontally while the end is inserted into the receiving groove.

4. The portable communication terminal for displaying information as claimed in claim 3, wherein the end of the positioning rod has a spherical portion and an outer peripheral groove adjacent to the spherical portion, and has an other end thereof provided with an elastic body.

5. The portable communication terminal for displaying information as claimed in claim 1, further comprising a pair of support arms integrally formed on the cover.

6. The portable communication terminal for displaying information as claimed in claim 1, wherein the plurality of openings include a first opening provided on the cover for exposing the displayed information after the sliding and rotational movements of the display device;

a second opening formed on an end of the cover; and

a third opening formed on an other end of the cover.

7. The portable communication terminal for displaying information as claimed in claim 1, wherein the cover and the at least one support arm are made of a metallic material.

8. The portable communication terminal for displaying information as claimed in claim 1, wherein both ends of the display device are of semi-cylindrical shape and both ends of the at least one support arm are of semi-circular shape for smooth rotational movement of the display device.

9. The portable communication terminal for displaying information as claimed in claim 1, wherein the display device is adapted to perform a 180°

rotational movement after a complete sliding movement away from the cover along the linear direction of the support arm and to be safely received in the cover after a complete rotational movement.

10. The portable communication terminal for displaying information as claimed in claim 2, wherein the positioning means includes a receiving groove formed on a bottom surface of the cover;

a support plate adapted to perform a sliding movement while a proximal end thereof is continuously placed in the receiving groove and to support the display device at a slant by rotating a distal end thereof away from the receiving groove concurrently with the sliding movement; and

an auxiliary plate having an end rotatably provided in the receiving groove and an other end rotatably connected to the support plate at a predetermined location for maintaining spacing between the cover and the support plate.

11. A portable communication terminal for displaying information comprising:

a cover;

a display device adapted to perform a sliding movement in a linear direction away from the cover, to perform, after the sliding liner movement, when within a predetermined rotation angle, to move again toward the cover when out of the predetermined rotation angle, and then to continuously face the cover; and

a plurality of openings formed on the cover for facilitating the sliding and rotational movements of the display device and for completely exposing the information displayed on the display device.
