INPUT DEVICE OF A PORTABLE TERMINAL WHICH DOES NOT HAVE A NECESSITY OF DIRECTLY PRESSING KEYS TO ENABLE A USER TO INPUT VARIOUS INFORMATION

摘要

PURPOSE: An input device of a portable terminal is provided to input data by using signals sensed by sensing switches, thereby inputting certain commands by shaking or inclining a portable terminal in certain direction without a user directly operating a key. CONSTITUTION: A spherical weight(110) has a certain mass inside a portable terminal to move in 6 directions when the portable terminal is inclined or shakes. Sensing switches(120,130,140,150,160,170) sense the movement of the spherical weight(110). A switch casing(180) fixes the sensing switches(120,130,140,150,160,170). A casing cover(190) opens/closes a top portion of the switch casing(180).
