Cellular phone and automatic revolution method thereof
First Claim
1. A cellular phone providing wireless communication, comprising:
- a main body having a key pad and a hinge thereof along a folding and unfolding axis;
a folder having a display displaying data received from the main body;
a driving source disposed on a lower portion of the folder along the folding and unfolding axis to generate a driving force;
a power transmission unit having one end coupled to the driving source and the other end coupled to the folder to transmit the driving force to folder to rotate with respect to the main body when the folder is in an open state; and
a rotation controller coupled to the power transmission unit, disposed in a housing installed at the hinge of the main body in a rotating axis perpendicular to the folding and unfolding axis to automatically and/or manually rotate the folder with respect to the main body.

Abstract
A folder type cellular phone and an automatic folder rotating method used with the folder type cellular phone includes a main body having a key pad and a hinge thereof in a first direction, a folder having a display displaying data received from the main body, a driving source disposed on a lower portion of the folder in the first direction to generate a driving force, a power transmission unit having one end coupled to the driving source and the other end coupled to the folder to transmit the driving force to folder to rotate with respect to the main body when the folder is in an open state, and a rotation controller coupled to the power transmission unit and disposed in a housing installed at the hinge of the main body in a second direction perpendicular to the first direction to automatically and/or manually rotate the folder with respect to the main body. The folder is automatically or manually rotated with respect to the main body when the folder is in an open state.

18. An automatic folder folding method used with a cellular phone providing wireless telecommunication, the method comprising:
-
inputting a rotation signal to a motor to rotate a folder with respect to a main body;
determining whether the folder is in an open or close state to rotate the folder according to the rotation signal;
determining whether a display of the folder is in an initial or opposite position when the folder is in the open state;
driving the motor in one of a forward direction and a reverse direction to rotate the folder according to a rotation direction determined by the initial position of the folder;
completing a rotation of the folder by a predetermined rotation angle; and
cutting off the rotation signal from the motor to terminate the rotation of the folder. - View Dependent Claims (19, 20, 21)

22. An automatic folder folding method used with a cellular phone providing wireless telecommunication, the method comprising:
-
inputting a rotation signal to a motor to rotate a folder with respect to a main body;
determining whether the folder is in an open state to rotate the folder according to the rotation signal;
determining whether a display of the folder is in an initial or opposite position when the folder is in the open state;
driving the motor in one of a forward direction and a reverse direction to rotate the folder according to a rotation direction determined by the initial position of the folder;
determining whether a rotation completion detecting sensor is in an on state to detect a rotation of the folder according to completion of the rotation of the folder by the motor; and
cutting off the rotation signal from the motor to terminate the rotation of the folder upon determining that the rotation completion detecting sensor is in the on state. - View Dependent Claims (23, 24, 25)

26. A cellular phone providing wireless communication, comprising:
-
a main body having a key pad and a hinge thereof in a folding and unfolding axis;
a folder having a display displaying data received from the main body;
a rotation unit having one end coupled to the folder and the other end coupled to an inside of the hinge in a rotation axis perpendicular to the folding and unfolding axis to allow the folder to be folded and unfolded with respect to the main body, and automatically or manually rotating the folder with respect to the main body according to a user selection when the folder is in an open state. - View Dependent Claims (27, 28)

29. A cellular phone providing wireless communication, comprising:
-
a main body having one of a key pad and a display, and having a hinge thereof along a folding and unfolding axis;
a folder having the other one of the key pad and the display, and coupled to the hinge to be folded and unfolded about the folding and unfolding axis with respect to the main body in a folding and unfolding direction perpendicular to the folding and unfolding axis;
a rotation unit having a first portion fixedly coupled to the folder along the folding and unfolding axis, a second portion fixedly coupled to the main body along the rotation axis, and a third portion coupled to transmit a driving force between the first portion and the second portion to rotate the folder in first and second directions about a rotation axis perpendicular to the folding and unfolding axis with respect to the main body. - View Dependent Claims (30, 31)
