The main reason is that the optical mouse system uses the optical module as the image capturing interface, so regardless of its weight or In terms of volume, it is more in line with the needs of traditional ball-sliding mice, and it is more accurate and correct to use the image of the original image of the original image of Wang Li, and the optical mouse is generally accurate and correct. Its work (4): the use of two sets of output sequence logic signal coding benefits to form the logical calculation of the x-axis and γ-axis to generate displacement based on the flat (four) thousand faces touched by the bottom of the mouse to form displacement; Brother 1 picture", the cross-section shown in the figure shows the known optical potential (2) y soil, the optical mode used by this kind of light, group 1〇' as shown in the figure, this is first given to the group 1 - a lens m, a first shot portion 102, a second refraction portion ig 1n, a second refraction portion 104, and a lens 1 0 5 are formed, and the middle subgroup is provided with a light-emitting element #m as a light source, Newton <; , , , , , , , , , , , , , , , , , , , , , , , , , , , The general system 5 M307804 uses a light-emitting diode (LED) as a light source, and above the second lens 〇5, an image signal extraction device 107 is provided; the optical module 10 is mainly utilized. 1 ed light source is irradiated on the image capturing surface A, so that the image can be clearly captured by the light source, so that the mouse can be used as an index displacement; then, as shown in the figure, when the light emitting element 1 〇6 emits a light source F After the light source is generated, the light source F is first transmitted through the first lens 101, and when the light is incident on the first refractive portion 1 〇2, the first refractive line F1 is generated, and the first refractive line Fi is re-shot. When the second refracting portion 103 is formed, the second refracting line F2 is further generated. When the second refracting line F2 passes through the third refracting portion 1 〇 4, the third refracting line F 3 ′ is formed and the second refracting line f 3 is finally formed. Illuminating an image capturing surface a forms an irradiation area F4, which is a plane used by the mouse, such as a table top. When the irradiation area F4 falls on the image capturing surface a, the image forming surface A has a certain The brightness of the image is taken by the illumination, that is, the image surface must be a rough surface (see enlarged view). When the angle of the source light is about 20 to 35 degrees, when it is irradiated to the rough surface of the image taking surface A, the shadow A1 is generated without the light source being irradiated to the concave portion A1.

Functional operation; υ, mainly by means of refracting light, the refracted light is formed into an illumination area 8 6 M307804 F 4 ' and the illumination area ρ 4 is irradiated to a position to create a shadow a of the concave surface A1 of the image surface A 11 causes image capture as a basis for logical operation, which uses the brightness of the illumination area F4, so that the image signal capture unit 1 〇7 can capture the shadow of the concave surface A1 of the image plane A from the position illuminated by the light source. Image (see the grid diagram of the optical signal β) 'However, this type of optical module 1 is in use, there is a problem, please refer to the figure, the image surface is the mouse I The plane to be touched, but if the material of the image surface A is smooth and flat, such as glass or acrylic, it will affect the image A. The shadow A1 shadow A11 will not work, so the image signal is captured. The image captured by unit 107 Wu error may occur i.e. σ 'and cause the mouse cursor is formed Tab or drift, therefore, this type of mouse can not be used on a smooth plane material. Another example is the "Receiving Method for Optical Signal Image" by the Republic of China Patent No. I 2 3 〇 3 5 9 , which is another application of the conventional optical module, which mainly produces a vertical projection beam of the light-emitting element. The optical axis uses the action of the beam splitter to transmit the light (optical axis) to the image contact surface below the transparent medium object. 1 The image of the image contact surface is reflected to the aforementioned beam splitter, and after multiple reflections, the image is provided for the image. The sensing component is captured, and # is mainly between the light-emitting component and the image sensing component, and the beam splitter allows the optical axis of the light to be refracted at the same point to reduce the phase error. [New content] M307804 In order to make the optical module violate the better effect, the creator analyzes and improves the structure of the optical 杈 group, and its main purpose is to provide a smooth and flat material that can still effectively function. The optical 杈 group ensures that the optical mouse can be operated with precision. The optical module for the creation of the mouse is mainly composed of a plurality of lenses, a plurality of refractive parts and a beam splitter, which can be integrally formed, and the components are integrated into one body to facilitate miniaturization, and the device is arranged in one. In the optical mouse, it is matched with a light-emitting element and an optical signal extracting device, and the transmission and refraction of the light source generates a coaxial vertical concentrated beam. When projected on an image capturing surface, the uneven reflecting surface is different. The reflectivity forms an optical signal (spot), and the optical signal capturing device receives the reflected light spot signal through the lens, which can effectively overcome the problem that the smooth surface or the finer surface of the glass is not obvious, so that the optical signal extraction process can be unaffected, and the vertical concentration is The reflective optical axis allows the optical signal capture device to accurately receive the optical signal, allowing the mouse to operate accurately even on the plane of the transparent material.

At this time, the second beam = the beam Η is refracted downward by about 90 degrees. To generate a third refracted light f5, after the refracted beam f5 is in contact with the image capturing surface a, the reflected-reflected beam f6 is reflected upward. At this time, the optical signal reflected by f6 passes through the lens 206 and is The optical signal picking device 2〇8 picks up the spot signal formed by the reflection of the image taking surface a (as shown in the square diagram in the figure), and the spot signal will not be lost. Please refer to the figure again. As shown, since the first condensing mirror 2 〇1, the first refracting portion 202, the second refracting portion 203, and the second condensing mirror 2〇4 are designed, the light source f can be refracted to form a light beam having a gradually decreasing diameter (first refracted light) Fl, the second refracted light f2), when the second condensing mirror 2 〇 4 concentrates the parallel beam F4 to reach the beam splitter, vertical downward refracted light (ie, the first refracted light f 5 and the reflected beam f 6 ) is formed, so Forming a spot signal; see the enlarged portion shown in the figure, due to the refracted third refracted beam f 5 , reflected light F6, the lens 2 0 6, the optical signal capturing device 208, and the image capturing surface a are coaxially perpendicular, and the concentrated light is projected on the image capturing surface a, and the reflective surface a of the uneven surface generates different reflectances to form the spot signal. The optical signal device 208 receives the reflected spot signal through the first 10 M307804 lens 206, and can overcome the smooth surface or the finer image capturing surface of the glass, so that the optical signal reflection can be unaffected, so that the mouse is in contact with it. Whether the image surface a is smooth and flat material, the reflected spot signal will not be limited by the material of the image surface A, and the optical signal extraction device 208 can be effectively connected and received the reflected spot. Signal (spot imaging). Please refer to FIG. 4, which is a preferred embodiment of the present invention. As shown in the figure, the lens 206 can also be formed separately, and the main & is to be attached to the optical module 20. A lens portion 206 is formed for the separately formed lens 206 to be mounted in the bearing portion 209.
