In addition to the optical displacement sensing module 41, the optical mouse 4 further includes a housing 40, a left button 42, a right button (not shown), a roller 43 and a circuit board 44. The circuit board 44 is disposed inside the casing 40, and the optical displacement sensing module 41 is disposed on the circuit board 44 and exposed to the bottom 401 of the casing 40 and the opening 303. The optical displacement sensing module 41 includes a light source 411, an optical lens group 412, a sensing component 413, and a control unit 414. The light source 411 is disposed on the circuit board 44 for generating a light beam B ^* , and the optical lens group 412 is used to direct and focus the beam B ^* . The sensing component 413 is disposed on the circuit board 44 for receiving the beam B ^* to generate a plurality of image signals.

In the preferred embodiment, the optical mouse 4 is a wired optical mouse, and the light source 411 is a laser diode, and the control unit 414 is a digital signal processor (Digital Signal Processor, DSP). In other preferred embodiments, the optical mouse can be connected to a wireless optical mouse using a wireless signal receiver, and the light source can also be a Light Emitting Diode (LED).

In the optical lens set 412, the optical lens set 412 includes a first focusing lens 4121, a second focusing lens 4122, a first reflecting mirror 4123, and a second reflecting mirror 4124. The first focusing lens 4121 is disposed in front of the light source 411, the first focusing lens 4121 and the second focusing lens 4122 are used to focus the beam B ^* , and the first mirror 4123 and the second mirror 4124 are used to change the beam B ^* . direction. In the preferred embodiment, the first focusing lens 4121 and the second focusing lens 4122 are convex lenses, and the first focusing lens 4121, the second focusing lens 4122, the first mirror 4123, and the second reflection of the optical lens group 412. The mirror 4124 is integrally formed. The process of the optical displacement sensing module 41 operating to cause the optical mouse 4 to generate a trajectory is described in the prior art, and therefore will not be further described.

When the tester wants to test the optical mouse 4 using the optical mouse test system 3, and the distance between the carrier 302 and the base 301 is equal to the first distance, the tester holds the housing 40 of the optical mouse 4 with his hand, and The optical mouse 4 is moved to move the optical mouse relative to the carrier 302 in the limiting slot 3021, that is, the optical mouse 4 is moved from one end of the limiting slot 3021 to the other end of the limiting slot 3021. During the movement of the optical mouse 4, the optical displacement sensing module 41 generates a corresponding trajectory according to the movement of the optical mouse 4, wherein when the distance between the carrier 302 and the base 301 is equal to the first distance, the computer The trajectory obtained by the host 31 in response to the movement of the optical mouse 4 is defined as a first trajectory T1, and the first trajectory T1 is displayed in the display screen 32 in a first color, as shown in FIG.

Next, please refer to FIG. 8. FIG. 8 is a schematic diagram showing the structure of an optical mouse at a second distance in a preferred embodiment of the optical mouse test system of the present invention. The tester touches the second operation button 306 to trigger the height adjustment module 304, so that the plurality of connection posts 3041 extend to a second height scale relative to the base 301 in response to the operation of the transmission gear 3042A and the transmission rack 3042B, so that the base 301 and the base 301 The distance between the carrier plates 302 is equal to a second distance D2, that is, the second distance D2 is 0.1 mm. Similarly, the tester holds the housing of the optical mouse 4 by hand, and moves the optical mouse 4 to move the optical mouse relative to the carrier plate 302 in the limiting slot 3021, that is, optically sliding. The mouse 4 is moved from one end of the limiting slot 3021 to the other end of the limiting slot 3021. During the movement of the optical mouse 4, the optical displacement sensing module 41 generates a corresponding trajectory according to the movement of the optical mouse 4, wherein when the distance between the carrier 302 and the base 301 is equal to the second distance D2, The trajectory obtained by the host computer 31 in response to the movement of the optical mouse 4 is defined as a second trajectory T2, and the second trajectory T2 is displayed in the display screen 32 in a second color. Next, the distance between the carrier 302 and the base 301 is repeatedly adjusted as described above and the optical mouse 4 is moved in the limiting slot 3021. Thereby, the computer host 31 obtains a third track T3 corresponding to one of the third distances. Corresponding to a fourth trajectory T4 of a fourth distance D4 and a fifth trajectory T5 corresponding to a fifth distance, and the third trajectory T3, the fourth trajectory T4 and the fifth trajectory T5 are respectively in a third color, A fourth color and a fifth color are displayed in the display screen 32 as shown in FIG.

It should be specially noted that, in order to facilitate the tester to determine whether the complex trajectories T1, T2, T3, T4 and T5 are correct by visual inspection, the trajectory control program 311 will not display the complex trajectories T1, T2, T3, T4 and T5 is displayed on the display screen 32. The trajectory control program 311 assigns different colors to the optical displacement sensing module 41 when the complex displacement signals corresponding to the complex trajectories T1, T2, T3, T4 and T5 are output to the host computer 31. The complex tracks T1, T2, T3, T4, and T5 of different colors are displayed on the display screen 32 for each track.

Since the position of the optical mouse 4 moving in the limiting slot 3021 is the same every time, the complex trajectories T1, T2, T3, T4 and T5 obtained by the test should overlap each other, and the trajectory overlap will easily cause the tester to misjudge. In order to avoid misjudgment, the track control program 311 separates the original track from the new track each time a new track is displayed, so that the complex tracks T1, T2, T3, T4, and T5 are separated without overlapping each other. So that the tester can see if each track is correct.

Since the optical mouse 4 moves linearly in the limiting slot 3021, the complex trajectories T1, T2, T3, T4 and T5 obtained by the test should also be straight lines under normal conditions. In FIG. 9, since the first track T1, the second track T2, and the third track T3 are all continuous lines and their tracks The length is equal to the distance that the optical mouse 4 moves linearly within the limiting slot 3021. The tester can determine that the first track T1, the second track T2, and the third track T3 are all correct, that is, between the carrier 302 and the base 301. When the distance is equal to the first distance D1, the second distance D2, and the third distance, the distances do not exceed the focal length of the optical displacement sensing module 41.

The fourth track T4 displayed on the display screen 32 is discontinuous, so the tester can determine that the fourth track T4 is incorrect, that is, when the distance between the carrier 302 and the base 301 is equal to the fourth distance D4. The fourth distance D4 exceeds the focal length of the optical displacement sensing module 41. Next, the reason why the fourth track T4 exhibits a discontinuous phenomenon will be described. Please refer to FIG. 10, which is a side view showing the structure of an optical mouse at a fourth distance in a preferred embodiment of the optical mouse test system of the present invention. When the optical mouse 4 is placed in the limiting slot 3021 of the carrier 302, the light source 411 of the optical displacement sensing module 41 generates the beam B ^* and focuses the beam B ^* through the first focusing lens 4121 through the first The light beam B ^{* of the} focusing lens 4121 passes through the opening 303 through the reflection of the first mirror 4123 and the second mirror 4124 to be projected onto the base 301. Then, the light beam B is reflected by the base 301, but the fourth distance D4 between the optical displacement sensing module 41 and the base 301 is slightly larger, so that a small portion of the light beam B ^* reflected by the base 301 enters the second focusing lens 4122. The fourth trajectory T4 is discontinuous.

In addition, although the fifth track T5 displayed on the display screen 32 is straight, but the length of the fifth track T5 is smaller than the distance of the optical mouse 4 in the limit groove 3021, the tester can judge that the fifth track T5 is incorrect. That is, when the distance between the optical displacement sensing module 41 and the base 301 is equal to the fifth distance, the fifth distance exceeds the focal length of the optical displacement sensing module 41. The reason for its formation is similar to that of the fourth track T4 described above, and since the fifth distance is larger than the fourth distance D4, the light beam B ^* reflected by the base 301 and unable to be focused by the second focus lens 4122 is more. Therefore, the sensing component 413 receives only a small number of image signals, so that the control unit 414 outputs a small number of displacement signals, and the corresponding fifth track T5 exhibits a phenomenon smaller than the linear movement distance of the optical mouse 4 in the limiting slot 3021. For example, the optical mouse 4 moves linearly within the limiting slot 3021 by a distance of 5 cm, while the fifth track T5 has a length of only 2 cm.

According to the above, the tester can visually display the complex trajectories T1, T2, T3, T4, and T5 displayed on the screen 32 to visually determine which trajectories are correct, and which trajectories are incorrect, and record the distances corresponding to the trajectories ( That is, the distance between the carrier 302 and the base 301 can obtain the range of the focal length of the optical displacement sensing module 41, so as to design the corresponding thickness of the bottom 301 of the housing 30 to ensure optical displacement sensing. The module 41 can operate normally.
