Abstract:
1. A joystick apparatus for a folder type portable terminal, which has a body housing provided in a lengthwise direction, and a folder rotatably coupled to the body housing, the joystick apparatus comprising: a first hinge module having a first embedded permanent magnet to couple the body housing to the folder so that the body housing rotates about the first hinge axis in a lengthwise direction with respect to the folder; a second hinge module having a second embedded permanent magnet to couple the body housing to the folder so that the body housing rotates about the second hinge axis when the body housing is raised perpendicularly to the folder; a first sensor unit provided on the first hinge module so as to detect a magnetic field of the first permanent magnet and to convert the magnetic field into electrical signals, as the body housing rotates about the first hinge axis with respect to the folder in a lengthwise direction; and a second sensor unit provided on the second hinge module so as to detect a magnetic field of the second permanent magnet and to convert the magnetic field into electrical signals, as the body housing rotates about the second hinge axis with respect to the folder in a clockwise or counterclockwise direction when the body housing is raised perpendicularly to the folder.
