Claim:
A portable comprising: a first housing provided with a display unit; a second housing coupled to one end of a side surface in a longitudinal direction of the first housing and rotating perpendicular to the longitudinal direction; and a hinge device rotatably coupling the second housing to the first housing and restraining the first housing from rotating in a stationary state in various angle positions with respect to the first housing; wherein the hinge device comprises: a first hinge base mounted on one of the first housing and the second housing; a second hinge base mounted on the other of the second housing and the first housing, coupled oppositely to the first hinge base, and rotating about a hinge axis; and a hinge stopper stopping the rotation of the second hinge base such that the hinge stopper is engaged with a stopping portion formed on the first hinge base wherein the first hinge base comprises: a first stopper hole formed in the first hinge base and located adjacent to the hinge axis, and the hinge stopper is engaged with the stopper hole when one end surface of the first housing faces one end surface of the second housing, wherein the first hinge base comprises both a rotation body extending along the hinge axis, and a locking segment extending perpendicularly to the hinge axis in one direction from a periphery of the rotation body, and the second hinge base has a flat board shape extending perpendicularly to the hinge axis, includes a rotation hole formed adjacent to one end of the second hinge base, and faces the locking segment as the rotation body is rotatably coupled through the rotation hole.
