Claim:
1. A position control apparatus using a joystick, comprising: a housing; a stick unit comprising a stick bar extending between a first end outside of the housing and a second end within the housing, the stick bar being capable of rotating about a pivot point between the first end and the second end of the stick bar when a load is applied to the first end thereof; a sensing unit disposed adjacent to the second end of the stick bar and capable of detecting a rotation position of the stick unit by sensing a position of the second end of the stick bar; a spring coupled to the stick bar at position outside of the housing; a motor which is driven when pressure is measured by a pressure sensor; a displaceable member coupled to the stick bar at position above the pivot point thereof and having the spring positioned between the first end of the stick bar and the displaceable member; and a pressing unit which applies pressure to the stick bar by driving the motor in proportional to the pressure measured by the pressure sensor as the displaceable member moves outwardly along the stick bar by operation of the motor while causing the spring coupled to the stick bar to be contracted, so as to restrict the stick bar from excessively rotating in an increasing direction of the pressure.
