Field of the Invention The present invention relates to a manually operated input device, and more particularly to an optical control input device that uses optical image changes as a signal reference. [Prior Art] In recent years, the multimedia entertainment market has flourished, and various software and hardware factories and businesses have continuously introduced new and better game software and game consoles to seize huge market opportunities, and more innovative and special. Software and hardware, as the main game control interface game rocker must of course continue to develop and improve to meet the user's needs. The β-used game rocker includes a base that houses the electronic components and a control rod that is erected on the base, and the control rod can move back and forth, left and right within a certain angle range, and a plurality of displacement sensors are arranged in the base. The position shift sensor can detect the displacement of the lever in all directions and convert it into a corresponding displacement signal. At present, most computer joysticks use variable resistors as displacement sensors. However, since the variable resistance system changes the resistance value by changing the contact point to convert it into a displacement signal, when operating the joystick, The variable resistance system generates mechanical friction. Under long-term friction, noise may be generated and the signal output may be incorrect. In the case of action software such as fighting, the user is accustomed to give the game joystick a larger The force makes the mechanical friction more serious, causing the displacement sensing 200811693 to be easily damaged and accelerating the life of the joystick. Moreover, the variable resistance sensor is susceptible to changes in temperature, humidity, and the like of the external environment, and also reduces the accuracy and stability of the signal output. Furthermore, the variable resistor is used as the displacement sensor. Before each operation of the joystick, it is necessary to correct the variable resistor to zero, so that the correct output signal can be obtained, which is not convenient in use. .

The function of the invention is to use the optical image change as the signal reference to output the signal in a non-contact manner, thereby avoiding the mechanical friction caused by the variable resistance of the displacement sensor, which causes the signal to be insensitive and damage. The problem is that the position coordinates are automatically corrected by the design of the zero point.
