Since I am familiar with the fact that I have a lot of money, I will not repeat them. »At the same time 'When the second projection beam is irradiated to the working plane 9〇, the reflection passes through the mirror 33 to the first to the _ beam to the material... < The second lens 41 refracts the second projection light first 疋54 . The second projection beam is filtered out through the second filter 54b, and the pixel of the signal receiving area 51 is not received, and the second projection beam is received, and the second image data is taken. When the Hetian user moves the computer input device 1 ,, the reflected light of the second projected light changes. Therefore, after the optical path travels through the above, the optical signal receiving area 51 receives the second corresponding to the movement of the computer input device 10. Projecting a beam of light, and then transmitting a new second image data. The second displacement data can be calculated by the control unit 52 comparing the optical signal receiving ▲ area 2 to obtain the (four) two image data. Since the urbanity calculation is carried out in various ways, it will not be described in detail. σ月麦知 "3B" is a schematic diagram of the optical path travel of the second embodiment of the present invention. As shown in FIG. 3, the 12 201013467 component structure of the computer input device 10 of the present invention substantially includes an optical sensing window, a first light source 30, a first lens 31, a first mirror 32, The second mirror 33, the second light source 4A, the second lens 41, the sensing module 50, and the circuit board 7A. The second embodiment is different from the first embodiment in that the surface area of the second lens 41 in the second embodiment is larger than the surface area of the second lens 41 in the first embodiment. First, the control unit 52 controls the opening and closing of the first light source 30 and the second light source 4A. When the first light source 3 〇 and the second light source 40 are turned on. At this time, the first 光源 light source 30 generates a first projected beam having a first wavelength to the optical sensing window. Then, the first projection beam is irradiated to the finger 8 and is reflected to the first lens 31. The first lens 31 refracts the first projected beam to the first mirror %. Next, the first mirror 32 reflects the first projected beam passing through the first lens 31 to the second mirror 33. The second mirror 33 reflects the first projected beam reflected by the first mirror 32 to the second lens 41. At this time, the second light source 40 generates a second projected beam having a second wavelength, which is reflected by the working plane 90 and then projected to the second lens 41, without passing through the second mirror 33. The second lens 41 is disposed between the second mirror 33 and the sensing module 5A. The first lens 41 is for refracting the first projected beam reflected by the second mirror to the illuminating unit 54. The first projection beam is emitted through the first filter, so that the pixel (not shown) of the optical signal receiving area 51 receives the first projection beam and obtains the first image data. When the mobile phone 80 moves in the optical sensing window u, the reflected light of the first projected light changes. Therefore, after the optical path travels through the above, the optical signal receiving area 51 receives the corresponding movement corresponding to the finger 8〇. A projection beam, and then 13 201013467 brazed new, first - image data. The first displacement data can be calculated by comparing the first image data obtained by the control unit 52 with the optical signal receiving area. Since the familiarity is known in the art, the correlation calculation is performed in various ways, and thus will not be described in detail.第一 After the first projection beam is irradiated onto the working plane 90, it is reflected to the second mirror 41: the second lens 41 refracts the second projection beam field light unit 54. The second projection beam is filtered out by the transparent filter to enable the optical signal receiving areas 51 and 2 (not shown) to receive the second projection beam and obtain the second image data. When the cultivator moves the computer into the farm, the reflected light 51 of the second projected light is changed. Therefore, after the optical path travels, the second projection beam moved by the input device 10 is taken by the optical signal receiving area. Enter d 5^ image data. The second image data obtained by the control unit 52 is compared with the second image data obtained by the optical signal receiving area 51, and is familiar with the knowledge of the art. As it will not be described in detail. See Figure 4A for the calculation of the phase. Therefore, Figure 4A is the first filter of the filter unit of the present invention. , , =: The light sheet is a structure in a stacked arrangement. Please refer to the structural schematic diagram of the second embodiment of the filter unit of Q々I”4ΒΓ. As shown in the "Fig. 4", the first 遽 and the second lap Mb of the calender unit % are in a lattice arrangement. "Please refer to Figure 5, which is a flow chart of the steps of the double-spectrum method of the computer input device in July. As shown in Figure 5, the dual-spectrum data input processing method of the computer input device of the present invention is applied to the input processing between the computer input device having the optical sensing device and a computer, and includes the following steps. : Turning on the light source 'to generate the first projected beam having the first wavelength to the optical sensing window' and turning on the second source to generate the second projected beam having the second wavelength to the working plane (step 200). The above working plane can be, for example, a table top or a mouse pad. The intensity and illumination time of the first light source and the second light source can be automatically adjusted by the control unit or adjusted by the user. When the first projection beam is irradiated to the optical sensing window, reflected light is generated, and when the second projection beam is irradiated to the optical sensing window, reflected light is generated, thereby providing a sensing module receiving unit having the filtering unit The reflected light of the first projected beam and the opposite of the second projected wire (face 21Q). The towel fine mold has the ability to detect the processing power of the image and the calculation processing capability of the displacement data. The filtered light unit filters out the reflected light of the first projected beam to obtain the first image data and transmits the reflected light of the second projected beam through the filtered light to obtain the second image data (step no). The filter 'light unit comprises a first filter and a second filter and a light. The first filter is used to filter out the first projected light having the first wavelength. The second filter is configured to filter out the second projected light having the second wavelength. In addition, the first light source and the second light source are different wavelengths. The first image data obtained by the control unit is compared to calculate the first displacement data and the second image data obtained by the comparison to calculate the second displacement data (step 230). The first displacement data and the second displacement data may include a coordinate displacement of the X-axis, a coordinate displacement of the γ-axis, a displacement direction of the χ-axis, and/or a displacement direction of the Y-axis of 201013467. The first displacement data and the second displacement data are stored to the storage unit. ^ Steps. The storage unit packs a temporary storage of the thieves. The first displacement data is stored in the first temporary storage in the storage unit, and the second displacement data storage # is temporarily stored in the storage unit.
