[0005] In US6,333,733, light sources, screens and optical sensors are installed on three axes of space, and the three light sources are activated simultaneously to complete the space control function, but US6,333,733 requires multiple light sources, multiple screens, and optical sensors. Therefore, issues such as energy consumption, number of parts, part positioning, and volume are unfavorable factors for its development.

[0006] In US2006 / 0086889A1, six light sources, six slit baffles and six optical sensors are set in the space, and the six light sources are activated to complete the space control function, but US2006 / 0086889A1 requires six light sources, slit baffles and optical sensors. Sensors, so energy consumption, number of parts, part positioning, and volume issues are unfavorable factors for its development

[0007] US6,480,183 uses the principle of capacitive sensing to sense the movement of the conductor of the mover to complete the plane displacement and rotation control functions. However, due to the use of capacitive sensing, the relative position of the conductor and the sensing plate is limited, and it is impossible to directly control the space. control function

[0008] US5,969,520 uses multiple magnetic components to sense the movement of the magnetic ball to complete the plane control function; however, the relative position of the magnetic ball and the magnetic component will affect the sensing accuracy of the magnetic component. In addition, the magnetic component is easily affected by external guides. The interference of magnetic objects affects the position determination, and the magnetic ball will also attract and collide with external magnetic objects.

[0009] US6,774,887 completes the plane control function through the contact between the conductor and the resistor, but the conductor and the resistor are prone to moisture or oxidation, resulting in poor contact, and to achieve the space control function, other conductors and resistors must be installed. Make the part volume and cost increase
