6. The portable apparatus as claimed in claim 1, wherein the second angle is a retaining angle and is smaller than 90°

.

7. The portable apparatus as claimed in claim 1, wherein the battery cover has at least one rubber member positioned on an outer surface thereof.

8. The portable apparatus as claimed in claim 1, wherein the main body has a sliding/swing housing positioned on an upper surface thereof and adapted to slide along a longitudinal direction of the main body while being parallel to and continuously facing the main body and to swing about a second hinge axis, which is spaced from and perpendicular to the first hinge axis and which is perpendicular to the longitudinal direction, while being parallel to and continuously facing the upper surface of the main body.

9. The portable apparatus as claimed in claim 8, wherein the main body has on its upper surface a pair of stereo speaker devices, a first keypad adjacent to the pair of stereo speaker devices, and a microphone device adjacent to the first keypad and the sliding/swing housing has, on its upper surface, a single key, a display device adjacent to the single key, and a second keypad composed of an array of a number of keys adjacent to the display device.

10. The portable apparatus as claimed in claim 9, wherein the first and second keypads are directly adjacent to each other in a first position wherein the sliding/swing housing is fully slid and the pair of stereo speaker devices and the display device are directly adjacent to each other in a second position wherein the sliding/swing housing is fully swung.

11. The portable apparatus as claimed in claim 1, wherein the main body has a camera lens and a lighting device adjacent to the camera lens positioned on an upper portion of the bottom surface thereof.

12. A portable apparatus comprising:

a main body;

a sliding/swing housing adapted to be moved while continuously facing an upper surface of the main body;

a first keypad composed of an array of a number of keys mounted on the upper surface of the main body;

a pair of stereo speaker devices mounted on the upper surface of the main body;

a microphone device mounted on the upper surface of the main body;

a battery cover coupled to the bottom surface of the main body in a predetermined position so that it can rotate about a first hinge axis toward or away from the main body and provided with a folding force, at less than a first angle relative to the bottom surface of the main body, in such a direction that it is folded on the main body, an unfolding force at the first angle or more, and a retaining force at a second angle for retaining the main body in an upright position at a slant; and

a battery pack removably attached to the battery cover.

13. The portable apparatus as claimed in claim 12, wherein the pair of stereo speaker devices are adjacent to the first keypad and the first keypad is adjacent to the microphone device.

14. The portable apparatus as claimed in claim 12, wherein the battery pack is integrally moved together with the battery cover.

15. The portable apparatus as claimed in claim 12, wherein the main body and the sliding/swing housing have different lengths.

16. The portable apparatus as claimed in claim 12, wherein the battery cover has a connection unit for connection to the battery pack and the battery pack is adapted to be moved along the inner surface of the battery cover to be attached to and detached from the connection unit.

17. A portable apparatus comprising:
