<p>A fold-type cellular phone has a top unit (200), a bottom unit (100) and a hinge (300) coupling together the top unit (200) and the bottom unit (100) while allowing the top unit (200) to turn and swivel with respect to the bottom unit (100). The top unit (200) is first unfolded from a first folded position to an attitude angle of 160 to 170 degrees, and then swiveled by 180 degrees to be folded onto the bottom unit (100) in a second folded position at an angle of 180 degrees. The swivel movement of the top unit (200) causes a cam assembly (303. 306a, 306b) to turn the top unit (200) from the attitude angle of 160-170 degrees to an attitude of 180 degrees in the second folded position, thereby allowing the top unit (200) to assume a suitable attitude with respect to the bottom unit (100).
