Description
Technical field
The utility model relates to a kind of optical mouse, the particularly a kind of camera lens module of optical mouse, relevant optical module and computer input unit of being used for.
Background technology
Computing machine is institute's role in daily life, from simple word processing of past, sequential operation, to audio-visual video, the electronic game amusement of complexity today.Shoulder the mouse of interface control important task, also evolve gradually along with making rapid progress of computer function, correspondingly, its induction technology is also from traditional roller, LED optics, progressive up-to-date up till now laser optics, and it is handling also from simple cursor control, extends to various additional effect such as having picture convergent-divergent, identification of fingerprint gradually, allows the computing machine user just can control all with a finger.
As shown in Figure 1, Fig. 1 is the backplan of an existing optical mouse 10.Optical mouse 10 comprises that a bottom surface 12, is arranged at the opening 14 on the bottom surface 12.By opening 14, optical mouse 10 can utilize a light emitting diode 18 (as shown in Figure 2) that irradiate light is arrived on the working face 40 (as shown in Figure 3) at optical mouse 10 places, and the mode by the image that presented on the acquisition of the scanner uni apace working face 40, the difference between the contrast institute image that the captures front and back.When the content of the image that captures changes to some extent, optical mouse 10 can calculate the displacement data of optical mouse 10 by the circuit in it, and this displacement data converts axial displacement signal to and is sent to a computing machine (not shown) by a cable 16 (or wireless transmission method).
In optical mouse shown in Figure 1 10, dust on the working face 40 even static can enter into the inside of optical mouse 10 by opening 14, and then the circuit in the optical mouse 10 is caused damage.
As shown in Figure 2, Fig. 2 is the combine component figure of optical mouse 10 inside.Optical mouse 10 comprises that also a light element 20, that is arranged at opening 14 tops is located at the circuit board 22, of light element 20 tops and is located at photoinduction element 24 and on the circuit board 22 and is arranged at light shield 26 on the circuit board 22, wherein, light emitting diode 18 is arranged on the circuit board 22.Photoinduction element 24 is used to capture the image that is presented on the working face 40 that optical mouse 10 slipped over, to analyze and to judge the displacement of optical mouse 10, light emitting diode 18 is used for the light source as photoinduction element 24, and the light that light shield 26 is used to avoid light emitting diode 18 to be sent directly is incident upon photoinduction element 24.
As shown in Figure 3, Fig. 3 is the side view of optical mouse 10.As shown in Figure 3, light emitting diode 18 can produce light 37, and light emitting diode 18 is in the face of first fully reflecting surface 32.In addition, because the design of the shape of light shield 26 is that the light 37 of avoiding light emitting diode 18 to be sent directly is incident upon on the photoinduction element 24, therefore, most light 37 can be penetrated towards first fully reflecting surface 32, and is totally reflected to second fully reflecting surface 34 downwards by first fully reflecting surface 32.After the total reflection of light 37 through second fully reflecting surface 34, can pass the opening 14 of bottom surface 12, and illuminate the working face 40 that optical mouse 10 is contacted.Working face 40 can reflex to convex lens 30 with the characteristic modulation of light 37 and with it, becomes total reflection light 38.Then, total reflection light 38 can be collected and focus on the photoinduction element 24 by convex lens 30, and photoinduction element 24 is judged direction and the distance that optical mouse 10 moves according to the variation of total reflection light 38.
Because light emitting diode 18 is arranged on the circuit board 22, that is to say, the relative position that light emitting diode 18 and light element are 20 can along with light emitting diode 18 be arranged at position on the circuit board 22, highly, and various factor such as inclined degree and changing, so, the position and the total reflection light 38 of working face 40 that light 37 illuminates also can change thereupon, like this, photoinduction element 24 judges that according to the variation of total reflection light 38 direction that optical mouse 10 moves just can produce error with distance.
In order to overcome above-mentioned shortcoming, assembler must guarantee very carefully that each light emitting diode 18 that is arranged on the circuit board 22 all has identical position, height and inclined degree, yet thus, optical mouse 10 certainly will have higher manufacturing cost.Nonetheless, light emitting diode 18 still rocks when optical mouse 10 is slided unavoidably, and therefore, photoinduction element 24 judges that according to the variation of total reflection light 38 direction that optical mouse 10 moves still can produce error with distance.
In addition, plurality of advantages such as concentrate owing to have light beam, the parent that the laser optics mouse more and more is subjected to the consumer looks at, but because the advantage that the light beam that it had is concentrated, more need fixing relative position between laser diode in the laser optics mouse and camera lens module, in other words, if the light emitting diode 18 in the optical mouse 10 is replaced with a laser diode, above-mentioned error phenomenon will be more remarkable.
If the light emitting diode 18 in the optical mouse 10 has replaced to laser diode, because the light that described laser diode sent is quite concentrated, so the setting that is used to collect and focus on the convex lens 30 of diffused ray 38 in the light element 20 just seems somewhat unnecessary.
