An actuating component of the multi-axis instruction outputting mechanism is moved in reciprocation at a first operating direction to output an instruction. The optical detecting module is disposed by the actuating component. An interval between the optical detecting module and the actuating component is varied according to a relative movement between the optical detecting module and the actuating component at a second operating direction, and the actuating component can be shifted between different gears. The optical detecting module determines the interval and related gearshift according to variation of a reflecting signal actuated by the actuating component, and utilizes the reflecting signal to acquire a movement of a feature point on the actuating component along the first operating direction to interpret the instruction. ## Claims ### Claim 1 An optical detecting device capable of determining gearshift, comprising: a multi-axis instruction outputting mechanism, an actuating component of the multi-axis instruction outputting mechanism being shifted in reciprocation at a first operating direction to output a corresponding instruction; and an optical detecting module disposed adjacent by the actuating component, an interval between the optical detecting module and the actuating component being varied according to a relative movement between the optical detecting module and the actuating component at a second operating direction, the actuating component being arbitrarily shifted between different gears, the optical detecting module determining the interval and related gearshift according to parameter variation of a reflecting signal actuated by the actuating component and utilizing the reflecting signal to acquire a movement of a feature point on the actuating component along the first operating direction so as to interpret the instruction, wherein the first operating direction is different from the second operating direction. ### Claim 2 (depends on 1) The optical detecting device of claim 1, wherein the actuating component is shifted to a corresponding gear by moving the optical detecting module relative to the motionless actuating component in reciprocation, moving the actuating component relative to the motionless optical detecting module in reciprocation, or moving the optical detecting module and the actuating component reversely in reciprocation. ### Claim 3 (depends on 1) The optical detecting device of claim 1, further comprising: a light emitting unit adapted to output a detecting signal; a light receiving unit adapted to receive the reflecting signal transformed by the detecting signal reflected from the actuating component; and an operating processor electrically connected to the light emitting unit and the light receiving unit, the operating processor analyzing the parameter variation of the reflecting signal and the movement of the feature point within an image formed by the reflecting signal, to determine a current gear of the actuating component and the corresponding instruction output by the actuating component. ### Claim 4 (depends on 3) The optical detecting device of claim 3, wherein the second operating direction is not perpendicular to a transmission direction of the detecting signal. ### Claim 5 (depends on 1) The optical detecting device of claim 1, wherein the parameter variation is intensity variation of the reflecting signal, and the interval is calculated by the optical detecting device according to the intensity variation. ### Claim 6 (depends on 3) The optical detecting device of claim 3, further comprising: a light sheltering unit disposed on the light emitting unit, the reflecting signal being correlative to a projective pattern formed by the light sheltering unit, the operating processor analyzing the projective pattern to calculate the interval. ### Claim 7 (depends on 6) The optical detecting device of claim 6, wherein the operating processor analyzes dimensions and/or boundary contrast of the projective pattern. ### Claim 8 (depends on 7) The optical detecting device of claim 7, wherein the operating processor analyzes an average value, a differential value, a maximal value, a minimal value and/or weighting relation about foresaid values of the dimensions and/or the boundary contrast. ### Claim 9 (depends on 1) The optical detecting device of claim 1, wherein a stereoscopic structure is formed on the actuating component, the reflecting signal is affected by the stereoscopic structure to generate a fringe pattern, the optical detecting device analyzes the reflecting signal having the fringe pattern to determine the interval and/or the movement of the feature point. ### Claim 10 (depends on 9) The optical detecting device of claim 9, wherein the stereoscopic structure is the feature point of the actuating component. ### Claim 11 (depends on 1) The optical detecting device of claim 1, wherein the actuating component is further moved in reciprocation at a third operating direction to output another instruction while shifting to any gear, and the third operating direction is different from the first operating direction and the second operating direction. ### Claim 12 (depends on 11) The optical detecting device of claim 11, wherein the reflecting signal is utilized to acquire another movement of the feature point along the third operating direction for interpreting another instruction.
