Claim:
A hinge for portable terminal connected to a first casing having a keyboard portion and a second casing having a display portion, comprising: a rotary hinge module configured to provide rotational movement to said first and second casing, and an opening/closing hinge module operatively joined to said rotary hinge module and configured so as to enable said first and second casings to pivotally open and close relative to one another; wherein said rotary hinge module comprises: a fixed member having a pivotally supporting cylinder and a mounting piece that secures said second casing to said fixed member; a first hinge pin having a first deformed head on one end and inserted lengthwise through said pivotally supporting cylinder to rotatably support said fixed member; a first cam mechanism mounted on the end of said first hinge pin having said first deformed head and configured to control the movement of said rotary hinge module; wherein said opening/closing hinge module comprises: an opening/closing member mounted on one cylinder portion of a cylindrical rotary member; a second hinge pin having a second deformed head and rotatably inserted into said cylindrical rotary member in a lengthwise direction; a second cam mechanism mounted on the end of said second hinge pin having said second deformed head and configured to control the movement of said opening/closing hinge module; wherein said first and second hinge pins are attached to one another by a fixing screw at said first and second deformed heads so as to operatively join said rotary and opening/closing hinge module; and wherein a first end portion of said pivotally supporting cylinder is abutted against a second end portion of said opening/closing member, said first and second end portions being configured so as to restrict rotation of said pivotally supporting cylinder when said first and second casings are at a first predetermined angle and to permit rotation of said pivotally supporting cylinder when said first and second casings are at a second predetermined angle.
