The partial spherical surface of the crucible is in contact with each of the beads of the ball 丄 22, so that the (four) ball 2 () is rotatably positioned on the housing M322576 - can protrude outside the through hole 121 or be located in the through hole 121 In the middle, $ and = face the beam splitter 3 1, and let the beam splitter 3 work outside the surface of the 3 work, the mirror element 3 2 will be ☆ private, soil ', = direction' The tampering ball 20, the beam splitter 3, the lens element 3 2, and the image sensing state 60 are arranged in the same direction. Finally, the fixed cover i 3 and the outer casing are combined with each other, and the ball 20 passes through the through hole χ3χ, and then the upper end of the partial spherical body 10 is fixed outside the cover 13 . Wherein, the above-mentioned structure can be changed differently, and it can be changed to. The seat 12 can be integrally formed with the outer casing η to integrally integrate the socket 2· into the housing space of the outer casing 1]. In the middle of the housing, the optical housing H body can be coupled to the housing 11 in the housing space of the housing 11. However, for the sake of convenience, when the outer casing 11 and the socket 12 are formed in a body, the seat 30 is preferably assembled, and the outer casing is light. 3◦-body molding, the seat! 2 is better in assembly, so as to facilitate assembly convenience. Please refer to the figure in the sixth figure, and please refer to the figure of the sixth person. When the light emits π, the optical axis of the projection light source generated by the 50 is 50, which can face and shoot toward the beam splitter 3 1, via the beam splitter. Under the use characteristic of the work, the incident light source can be partially reflected, and the partially transmitted optical object is such that the optical axis D 1 of the partially transmitted projection light source passes through the other hole ια 2 . The optical axis DM of the partially reflected projection light source is projected onto the partial spherical surface of the trackball 20 (ie, the image capturing area 21, such as the sixth frame), and the spherical surface of the trackball 20 The image is then reflected back to the outer surface of the beam splitter 3 1 1 , and the light captured by the image (4) overlaps with the optical axis D 2 of the source of the splitter 3 projection light 11 M322576. Then, the optical axis R1 of the partially reflected captured image can be projected to the light emitting element 5 by the action of the beam splitter 31, and the optical axis R 2 of the partially transmitted captured image can be projected 'to the lens element 3 2 For the image sensor 60 to capture the image that is applied through the lens element 32. When the trackball 2 〇 rotates, the image sensor 6 can detect the moving distance and direction of the trajectory 2 ,, and then calculate a displacement data. • In the above description, the optical axis D of the projection light source generated by the light-emitting element 50 can be reflected by the beam splitter 3 once or more directly in the direction perpendicular to the vertical direction, and the optical axis D 2 of the projection light source is reflected to The image capturing area of the ball 20 is captured. The rain source causes the light source (beam) to be uniformly projected onto the image capturing area 2 1 (ie, the projection area of the light beam and the image capturing area completely overlap). And because the optical axis D 2 of the projection light source is overlapped with the light source R of the spine image, and then projected to the beam splitter 3丄, and then projected to the lens element 32, so that the full uniformization can be achieved. The image causes the image sensor 6 to obtain a complete image for comparison and to determine the moving distance and direction of the trailing ball 20 to calculate a complete displacement data. In addition, please refer to the seventh figure (and please refer to the sixty-eighth figure). According to the usage characteristics of the mirror 3, the structure position setting of the creation can be changed differently, which is different from the above. The outer raft 11 is disposed on the circuit board 40 in a direction parallel to the circuit board 4 ,, so that the optical pedestal 3 ◦ passes through the hole i 1 2 to be located in the accommodating space 1 1 1. The component .5 〇 directly protrudes into the accommodating space ,, and the beam splitter 3 1 also faces the through hole in the oblique direction, and the inner surface of the beam splitter 1 1 2 is inclined to the ground For the through hole 1 2 1 and the obstructing ball 2 〇, the outer 3 1 ! is facing the light emitting element 5 〇, so that the lens element 3 12 M322576 'and thus the trackball 2 is arranged in the same direction 2 is located close to the The direction of the track 2 0 0, the beam splitter 3 1 and the light-emitting element 5 are horizontal (horizontal). When the light emission τ ε 5 〇 projects the optical axis D of the light source, and the illuminating mirror 3 1 passes through its ❹ characteristic, the optical axis β 1 of the partially transmitted projection light source is projected toward the through hole 1 2 1 and is projected to the sculpt. The spherical surface of the ball 2 , and the optical axis D 2 of the partially reflected projection light source are reflected toward the hole 1 , and the spherical image of the track ball 20 is reflected back to the inner surface of the beam splitter 3 3 3 1 2 The light (4) of the image is superimposed on the light source D 1 transmitted through the beam splitter 3丨. And then, through the action of the beam splitter 3, the optical axis R i of the partially reflected image is projected onto the lens element 3 2 for the image sensor 6 to capture the image through the lens element 3 2 . And a partially transmissive optical axis R 2 of the acquired image can be projected onto the light emitting element 5 〇. When the tracking ball 2 turns, the image sensor 60 can capture the moving distance and direction of the trackball 2 ,, and then calculate a complete displacement data. The direct light generated by the evening light is generated by the _, the area 2 is shot in the image capturing area 2!, and the light source R of the projected light source is twitched and the light source R is overlapped, and then 3 1 'Further re-projecting to the lens element 32, so that the captured image can be achieved, so that the image sensor 6 can achieve the same effect as described above. ~ Like to make this creation department can be explained by the above description, as shown in the eighth figure, 13 M322576 is supplied for the outer casing 7 1a of a keyboard 7 〇a The ruling ball 2 is based on the priest. The machine (figure) is electrically connected, the singer, the singer, and the same day can be used with the computer master. Of course, this creation can also be used in F v / clothing, such as: notebook or handheld communication, too = on the display of the cursor. In addition, it is particularly worth mentioning that the design of the housing 1 Q described above can be made differently, such as the intersection of the keyboard 7 0 a μ μ 7 1 from the main two concave - 笠夕之The surface of the outer 脰7 la is directly visited to form a concave accommodating space (figure omitted), which can directly =f"20 and the trackball 20 is properly solidified: The components (such as the transfer plate, the splicing element, the wire holder and the ^ are disposed in the outer casing 7 la in the same manner, can also achieve the same effect. One of the above 5, see the ninth figure, the creation It can also be applied to the housing 7丄b outside the =7 0 b, so that the trajectory 2 is tied to the heart and at the same time via the mouse 7 Q b and the computer host (not shown) The displacement data is controlled and the cursor of the computer host is displayed. However, 'When in use, the ball 2 is moved on the surface, as on the desktop, mirror or glass surface, and the 2G system is used. In contact with the contact surface, the light source of the internal light-emitting element (not shown) is projected onto the spherical surface of the trackball 2, not in a direct manner Projected on the contact surface 'i.e., using the trackball 2 〇 as the indirect object and the contact surface contact 'to make the light source of the light-emitting element unrestricted from the contact surface' to avoid the optical mouse in the use surface as conventionally described There are deficiencies in the above. However, the above description is only a preferred and feasible embodiment of the present creation, and therefore, the patent (4) of the M322576 = "the use of this creation specification and the internal structure of the schema" is the same.
