The present invention relates to a position control apparatus that is capable of controlling the position of an object with a joystick and, more specifically, to a position control apparatus using a joystick that is capable of limiting the movement of an object when pressure is detected to be acting on an object. The position control apparatus using a joystick according to the present invention includes a stick means, a detection means, a motor, and a pressurization means. The stick means is provided with a stick bar that is capable of rotating about one point between one end and the other end when a load acts on the one end. The detection means detects a rotation position of the stick means. The motor is driven when pressure is measured by a pressure sensor. The pressurization means applies pressure with the driving of the motor in proportion to the pressure measured by the pressure sensor so as to impede the stick bar rotation in a direction in which the pressure increases. According to the present invention, the motor is operated when the pressure is detected through the stick bar rotation so as to rotate a first gear and a second gear. Then, a spring contracts to apply pressure to the stick bar. Then, the pressure is transmitted to an operator operating the stick bar and the operator can detect the pressure. In this case, an increased load is required for moving the stick bar so as to move the object, and thus an operator misoperation can be prevented. |
