Description

Mouse roller device

The divisional application is based on the divisional application of Chinese patent application with the application number of CN 201910780794.0, the application date of 2019, 08 and 22 months and the name of the invention of a mouse roller device.

Technical Field

The present invention relates to a mouse wheel device, and more particularly, to a mouse wheel device for reading rotation information by using optical technology.

Background

The roller module on the top of the mouse is mainly used for controlling the rolling of computer screen pictures, and the rotating speed of the roller operated by fingers of a user is directly related to the rolling speed of the screen pictures and the picture range capable of being browsed by the user in unit time.

The rolling speed of the roller is typically detected by an encoder. The most widely used mechanical encoder on the mouse is simple in structure, easy in main control programming and provided with mechanical scale hand feeling compared with a grating encoder. The mechanical encoder is provided with a turntable, and when the turntable of the mechanical encoder is driven by the rotation of the mouse roller, a plurality of contacts on the turntable are in electric contact with fixed contacts on the base, so that spaced conducting signals are generated.

The grating encoder is arranged on two sides of the grating structure by using a group of light receiving and transmitting modules, and the grating structure is used for intercepting and conducting light signals when the roller rolls and can be used for detecting the rotating speed of the mouse roller. An external optical code disc linked by a gear or a pivot and a roller can be used as a grating structure, so that the optical transceiver module can generate intermittent signals corresponding to the rotation speed of the roller along with the rotation of the optical code disc.

Meanwhile, the requirement that the roller on the top surface of the mouse can emit light brings new challenges for the mouse adopting the grating encoder to detect the rotating speed of the roller.

Detailed Description

The foregoing and other aspects, features and advantages of the invention will be apparent from the following more particular description of a preferred embodiment, as illustrated in the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are referred to only in the direction of the attached drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.

Referring to fig. 1 to 4, fig. 1 is an external view of a mouse 1 according to an embodiment of the present invention, fig. 2 is an exploded view of a mouse wheel device 10 according to a first embodiment of the present invention, and fig. 3 and 4 are schematic views of the mouse wheel device 10 according to the first embodiment of the present invention at different viewing angles. The mouse wheel device 10 of the mouse 1 is partially exposed out of the opening of the housing 2 for the user to touch. The mouse wheel device 10 may mainly include a base 12, a wheel module 14, a light shielding element 16 and a light detecting module 18. The top side of the kettle-shaped support 20 of the base 12 is open and is used for bearing the roller module 14; the supporting member 20 is pivotally connected to the front frame 12a and the rear frame 12b of the base 12 along the longitudinal direction Y, so that the roller module 14 and the supporting member 20 can rotate laterally along the deflecting direction R. The base 12 may include a circuit board (not shown), or at least a portion of the surface of the base 12 may include circuitry.

The roller module 14 may be formed by combining a wheel axle 22 and a hollow roller member 24. The axle 22 may include a tread 26, a pivot 28, and a plurality of spoke ribs 30. The spoke ribs 30 may be coupled to the pivot 28 and disposed within the tread 26. The pivot 28 is rotatably disposed on the support 20 along the axial direction D, and the pivot 28 in this embodiment is a cylindrical bearing including a ratchet 28a, wherein the pivot 28 is connected to a plurality of spokes 30 and extends to the outside of the wheel axle 22 along the axial direction D to connect with the ratchet 28a, and the ratchet 28a can cooperate with an additional adjusting element for switching the rolling mode and the operation feeling of the roller module 14. For example, in some embodiments, the tread 26 portion of the axle 22 may be formed of a metallic material that is capable of high-speed inertial rotation during operation of the mouse wheel device 10, which may provide a wide scroll viewing range in applications such as screen scrolling. The roller member 24 may be disposed on the periphery of the roller surface 26 to serve as a contact interface for a user to operate the mouse roller device 10.

The photo-detection module 18 includes a photo-emitter 36 and a photo-receiver 38 respectively disposed on a first side and a second side of the roller module 14 opposite to each other. The arrangement of the light emitter 36 and the light receiver 38 is not limited to that shown in fig. 2 to 4, i.e., the positions of the light emitter 36 and the light receiver 38 may be interchanged. The support 20 may have a break 40. The opening direction of the perforation 40 is not limited to that shown in fig. 2 to 4. The optical signal S projected by the optical transmitter 36 passes through the hole 40 of the supporting member 20, the roller module 14 and the light shielding element 16, and is received by the optical receiver 38. With the rotation of the roller module 14, the optical signal S is intermittently stopped by the light-shielding region 32 or passes through the light-transmitting region 34. The optical receiver 38 can obtain the behavior information to be expressed by the user operating the roller module 14 according to the receiving state, the receiving frequency and the receiving time of the optical signal S.

The shading element 16 is used for providing a grating structure, and may be composed of a plurality of shading areas 32 and a plurality of light-transmitting areas 34, and may be alternately arranged on the wheel shaft 22 or the roller member 24 around the shaft direction D. Generally, the shaded region 32 may be perpendicular to the pivot 28. The shading element 16 may further comprise an outer annular region 42 and an inner annular region 44. The outer annular region 42 may connect the outer ends of each light-shielding region 32, and the inner annular region 42 may connect the inner ends of each light-shielding region 32. In this embodiment, the light-shielding element 16 can be an independent opaque sheet, that is, the light-shielding region 32, the outer ring region 42 and the inner ring region 44 are all made of opaque material, and the light-transmitting region 34 is a hollow region between the light-shielding region 32, the outer ring region 42 and the inner ring region 44. The shade element 16 would be secured to the side of the hub 22. Specifically, the outer ring region 42 of the shade element 16 may be attached to the side edge of the tread 26 and/or the junction of the outer end side edge of each spoke 30 with the tread 26; the partial shading areas 32 of the shading element 16 are attached to the spoke ribs 30, so that the shading areas 32 and the light-transmitting areas 34 can be alternately arranged on the wheel shaft 22 or the roller 24 around the shaft direction D; the inner ring section 44 may be attached to the side edge of the pivot 28 and/or the connection of the inner end edge of each rib 30 to the pivot 28. The ribs 30 do not have to have light-transmitting properties, and the thickness of each rib 30 is preferably equal to or less than the width of each light-shielding region 32 of the light-shielding element 16, so that the transmission of the optical signal S is controlled by the light-shielding region 32 and the light-transmitting region 34 of the light-shielding element 16 without being interfered by the ribs 30.

In the first embodiment, the shading element 16 can be selectively attached to one side of the wheel axle 22 and/or the roller 24. If the shade element 16 is attached to the axle 22, the shade element 16 can be attached to the edge of the rib 30 with at least one of the shade region 32, the outer annular region 42, or the inner annular region 44, and the optical signal S output by the optical transmitter 36 can pass through the gap between the light transmissive region 34 of the shade element 16 and the rib 30 to the optical receiver 38; in this case, the material of the roller member 24 is not limited. If the shading element 16 is attached to the roller member 24, the shading element 16 can be attached to the side surface of the roller member 24 by using at least one of the shading area 32, the outer ring area 42 or the inner ring area 44, and the roller member 24 is preferably made of a transparent material; in this embodiment, the shading element 16 can be directly formed on the side or inside of the roller member 24, and the variation can be determined according to the design requirement.

The number of ribs 30 is not limited to the embodiment shown in fig. 2-4, as long as it is sufficient to stably support the tread 26 on the pivot axle 28 in accordance with the design requirements of the present invention. The number of the light-shielding regions 32 and the light-transmitting regions 34 can be designed according to the sampling frequency or the recognition accuracy of the light detection module 18. The light-shielding regions 32 and the light-transmitting regions 34 should have the same number, and the number of the light-shielding regions 32 and the light-transmitting regions 34 may be greater than or equal to the number of the ribs 30. However, the roller with the grating structure is usually manufactured by opening a mold, so that the cost is expensive and it is difficult to adjust the number of gratings. Since the manufacturing cost and yield of the number of ribs 30 of the wheel axle 22 are limited by the molding technique, the number of optical signals affecting the rolling operation detected by the optical detection module 18 can be detected by the wheel module 14 and the wheel axle 22 in one rotation. The meaning of the present embodiment that the spoke ribs 30 are not used as the grating structure is that when the number of times of the light signal that can be received per rotation is not limited by the spoke ribs 30, the wheel module 14 and the wheel axle 22 that are relatively expensive can be shared by mouse products of different functional types, and the benefits of sharing the wheel axle 22 and highly customizing the grating structure can be realized by adjusting and modifying the light shielding element 16 with low cost.

Referring to fig. 5 to 7, fig. 5 to 7 are schematic views of the shading element 16 combined with the axle 22 according to various embodiments of the present invention. In the embodiment shown in fig. 5, the light shielding element 16 may have a light shielding region 32, a light transmitting region 34, an outer ring region 42 and an inner ring region 44; the outer ring area 42 is disposed on the side of the tread 26 of the wheel axle 22, the inner ring area 44 is disposed on the side of the pivot 28 of the wheel axle 22, and the light shielding area 32 is connected between the outer ring area 42 and the inner ring area 44 and can be used to shield the spoke ribs 30. In the embodiment shown in fig. 6, the light-shielding element 16 may have only the light-shielding region 32, the light-transmitting region 34 and the outer ring region 42; the outer ring section 42 is disposed laterally of the wheel face 26, and the shaded region 32 extends inwardly from the outer ring section 42, the shaded region 32 being capable of shading the spokes 30, and portions of the shaded region 32 being not shaded by the spokes 30. In the embodiment shown in fig. 7, the light-shielding element 16 may have only the light-shielding region 32, the light-transmitting region 34 and the inner ring region 44; the inner ring section 44 is disposed at a side of the pivot shaft 28, the shielding section 32 extends outwardly from the inner ring section 44, the shielding section 32 can shield the spoke ribs 30, and a portion of the shielding section 32 is not shielded by the spoke ribs 30.

Referring to fig. 8 to 11, fig. 8 to 11 are schematic views of the light shielding element 16 and the roller element 24 according to various embodiments of the present invention. In the embodiment shown in fig. 8, the light shielding element 16 may have a light shielding region 32, a light transmitting region 34, an outer ring region 42 and an inner ring region 44; the outer ring area 42 and the inner ring area 44 are disposed on the side of the roller element 24 or the outer ring area 42 and the inner ring area 44 are disposed on the outer edge and the inner edge of the roller element 24, respectively, and the light shielding area 32 is connected between the outer ring area 42 and the inner ring area 44. In the embodiment shown in fig. 9, the light shielding element 16 may only have the light shielding region 32, the light transmitting region 34 and the outer ring region 42; the outer ring area 42 is disposed on the side of the roller member 24 or on the outer edge of the inside of the roller member 24, and the shading area 32 is disposed on the roller member 24 extending inward from the outer ring area 42.

In the embodiment shown in fig. 10, the light shielding element 16 may only have the light shielding region 32, the light transmitting region 34 and the inner ring region 44; the inner ring area 44 is disposed on the side of the roller member 24 or on the inner edge of the roller member 24, and the light shielding area 32 extends outward from the inner ring area 44 and is disposed on the roller member 24. In the embodiment shown in fig. 11, the light shielding element 16 may have only the light shielding region 32 and the light transmitting region 34; the light-shielding regions 32 are disposed on the sides or inside of the roller member 24, and the light-transmitting regions 34 are spaces between adjacent light-shielding regions 32. In the above embodiment, the light shielding element 16, if a separate opaque sheet, is disposed on one side of the wheel axle 22 or the roller 24 in an attaching manner. If the roller member 24 is made of a transparent material, the light-shielding element 16 can be formed by a light-shielding ink layer coated on the transparent roller member 24 or an opaque laser engraving alteration layer (or opaque laser engraving alteration layer) generated by processing the transparent roller member 24, in addition to being attached by an independent opaque sheet.

In the aforementioned embodiments shown in fig. 2-11, when the supporting member 20 and the roller member 24 are both transparent, the mouse roller device 10 may further include a light-emitting element disposed at an outer adjacent side of the supporting member 20, the light-emitting element can output illumination light, which is partially refracted and partially reflected by the supporting member 20 and the roller member 24 to pass through the mouse roller device 10 upward.

Referring to fig. 12 to 14, fig. 12 is an exploded view of a mouse wheel device 10 'according to a second embodiment of the present invention, and fig. 13 and 14 are schematic views of the mouse wheel device 10' according to the second embodiment of the present invention at different viewing angles. In the second embodiment, the elements having the same numbers as those in the first embodiment have the same structures and functions, and the description thereof will not be repeated. The difference between the second embodiment and the first embodiment is that the mouse wheel device 10' further includes a light emitting element 50, the light emitting element 50 is electrically connected to a circuit board (not shown) on the base 12; in addition, the wheel module 14 'of the mouse wheel device 10' may include an axle 52 and a transparent wheel member 54. A transparent roller member 54 is rotatably mounted on the support member 20 in conjunction with the axle 52. The light-emitting element 50 is used for outputting illumination light to the inside of the transparent roller 54, and the illumination light passes through the transparent roller 54 after being reflected, so that the transparent roller 54 can be in a light-emitting state.

In the preferred embodiment, the light guide surface 58 is a conical surface with a straight or circular cross-sectional edge, and the wall 60 is perpendicular to the pivot 56, but the application is not limited thereto. The light guide surface 58 and the wall surface 60 are light transmissive, but the light guide surface 58 is surface treated to increase reflectivity. Transparent roller members 54 may be mounted about the periphery of the axle 52. The light emitting end of light emitting element 50 may extend into transparent roller member 54 or be located outside transparent roller member 54 but directed toward the interior of transparent roller member 54. The light emitting element 50 may comprise an LED or other light source directly disposed at the elevated light emitting end, or the light source may be located at other positions of the light emitting element 50 and emit light from the light emitting end through the light guide. The light-emitting device 50 can provide at least a portion of the illumination light to the axle 52 inside the transparent roller 54, and the illumination light is reflected by the light-guiding surface 58 of the axle 52 and will be emitted through the transparent roller 54 to the outside, i.e. the mouse wheel device 10' has a light-emitting function.

If the light blocking member 16 of the mouse wheel device 10' is a separate opaque sheet, it can be attached to the side of the transparent roller member 54. If the shade element 16 is a separate opaque sheet and the axle 26 is made of a transparent material, the shade element 16 can be attached to the side of the axle 56 and/or the transparent roller member 54. In addition, when the axle 26 is made of a transparent material, the shading area 32 of the shading element 16 may be a shading ink layer formed on the light guiding surface 58, the wall surface 60 or the inside of the axle 26; alternatively, the opaque region 32 may be an opaque layer of laser engraving formed on the light guide surface 58, the wall surface 60, or the inside of the axle 26. Accordingly, the light-shielding region 32 of the light-shielding element 16 can also be a light-shielding ink layer or an opaque laser-engraved altered layer formed by partially processing the transparent roller 54.

As shown in fig. 8 to 11, the light shielding element 16 of the second embodiment may have various modifications. When the light shielding element 16 includes the light shielding regions 32, the light transmitting regions 34, the outer ring regions 42 and the inner ring regions 44 are respectively disposed on the outer edge and the inner edge of the side surface of the wheel axle 52 or the transparent roller member 54, the light shielding regions 32 are connected between the outer ring regions 42 and the inner ring regions 44, and the light transmitting regions 34 are gaps between adjacent light shielding regions 32. When the shading element 16 only includes the shading area 32, the light-transmitting area 34 and the outer ring area 42, the outer ring area 42 is disposed on the outer edge of the side surface of the wheel axle 52 or the transparent roller member 54, the shading area 32 extends inward from the outer ring area 42, and the light-transmitting area 34 is a hollow area between adjacent shading areas 32. When the shading element 16 only includes the shading areas 32, the light-transmitting areas 34 and the inner ring areas 44, the inner ring areas 44 are disposed on the inner edge of the side surface of the wheel 52 or the transparent roller 54, the shading areas 32 extend outwards from the inner ring areas 44, and the light-transmitting areas 34 are gaps between adjacent shading areas 32. When the shading element 16 only includes the shading region 32 and the light-transmitting region 34, the shading region 32 is disposed at the side of the axle 52 or the transparent roller member 54.

Referring to fig. 15 to 20, fig. 15 to 17 are schematic diagrams of the light shielding element 16 and the axle 52 according to different embodiments of the present invention, and fig. 18 to 20 are schematic diagrams of the light shielding element 16 and the hollow transparent roller 54 according to different embodiments of the present invention. As shown in fig. 15, the shading area 32 of the shading element 16 can be disposed on the wall 60 of the axle 52 in a manner of a shading ink layer or a light-proof laser-engraving-modified layer, and the shading area 32 is perpendicular to the pivot 56. As shown in fig. 16, the shading area 32 of the shading element 16 can be disposed on the light guiding surface 58 of the axle 52 in a manner of a shading ink layer or an opaque thunder-carving alteration layer, and the shading area 32 is not perpendicular to the pivot 56. As shown in fig. 17, the shading area 32 of the shading element 16 can be disposed inside the axle 52 in a manner of being light-proof and laser-proof, for example, between the light guiding surface 58 and the wall surface 60, and at this time, the shading area 32 can be selectively perpendicular or not perpendicular to the pivot 56.

As shown in fig. 18, the shade region 32 of the shade element 16 can be disposed adjacent to the wall 60 of the transparent roller member 54 or on the first side facing the light emitter 36 in the manner of a layer of a shade ink or an opaque laser engraving altered layer, with the shade region 32 perpendicular to the pivot axis 56. As shown in fig. 19, the shading area 32 of the shading element 16 can be disposed on a second side of the transparent roller member 54 facing the light receiver 38 or adjacent to the light guiding surface 58 in a manner of a shading ink layer or an opaque laser engraving altered layer, the first side is opposite to the second side, and the shading area 32 is perpendicular to the pivot 56. As shown in fig. 20, the light-shielding region 32 of the light-shielding element 16 can be disposed inside the transparent roller member 54 in a manner of being light-proof and laser-proof, i.e., between the first side and the second side, in which case the light-shielding region 32 can be selectively perpendicular or not perpendicular to the pivot 56. In the above embodiments, the light-transmitting regions 34 of the light-shielding elements 16 are regions between adjacent light-shielding regions 32.

Referring to fig. 21, fig. 21 is a partial structural schematic view of a mouse wheel device 10' according to a second embodiment of the invention. The wall 60 of the axle 52 is perpendicular to the pivot 56 and thus serves to shield the hollow of the transparent roller member 54 from one side. The light guide surface 58 of the axle 52 is received in the hollow region of the transparent roller 54, so that the illumination light output from the light emitting element 50 is reflected by the light guide surface 58 to generate a light emitting effect on the transparent roller 54. In the second embodiment, the light guide surface 58 is designed as a cone-shaped structure, and the structural features such as the height, width and inclination angle of the cone-shaped structure are not limited to the aspect shown in fig. 21 and can be determined according to the design requirements. The shape of the light guide surface 58 is not limited to the tapered structure shown in fig. 21, and the cross-sectional shape of the light guide surface 58, which can uniformly reflect the illumination light to the top surface of the transparent roller 54, meets the design requirements of the light guide surface 58 of the present invention. Generally, the axle 52 and the transparent roller 54 lacking the hollowed-out area cannot be used as a grating structure. In the embodiment, when the light shielding element 16 is disposed on the wall 60 of the axle 52, the light emitter 36 and the wall 60 of the light detection module 18 are disposed on the same side (the first side) of the roller module 14, and the light receiver 38 and the light guide surface 58 are also disposed on the same side (the second side) of the roller module 14. The light signal S projected by the light emitter 36 passes through the wall 60, the light guide surface 58 and the light shielding element 16 of the axle 52, or passes through the wall 60, the light shielding element 16 and the light guide surface 58, or passes through the light shielding element 16, the wall 60 and the light guide surface 58, and is received by the light receiver 38. That is, the light signal S enters from the wall 60 and exits from the light guide surface 58, so that the axle 52 having the light guide surface 58 without a hollow area and not easy to penetrate can also be combined with the light shielding element 16 as a grating structure.

Referring to fig. 22 to 24, fig. 22 is an exploded view of a mouse wheel device 10 "according to a third embodiment of the present invention, and fig. 23 and 24 are schematic views of the mouse wheel device 10" according to the third embodiment of the present invention at different viewing angles. In the third embodiment, the elements having the same numbers as those of the previous embodiments have the same structures and functions, and the description thereof will not be repeated. The difference between the third embodiment and the previous embodiments is that the wheel module 14 "of the mouse wheel device 10" may include a first half-wheel shaft 62, a second half-wheel shaft 64, and a hollow wheel member 66. The first half axle 62 and the second half axle 64 are rotatably provided at the support 20. The first and

second half axles

62, 64 have first and second light guide surfaces 68, 70, respectively. Roller member 66 is made of a transparent material and may be disposed between first axle half 62 and second axle half 64. The light emitting element 72 of the mouse wheel device 10 "is selectively inserted into the interior of the wheel member 66 through at least one of the first half axle 62 and the second half axle 64. At least a portion of the illumination light output by the light emitting element 72 can pass through the roller member 66 by being reflected by the first light guiding surface 68 and the second light guiding surface 70, so that the mouse wheel device 10 ″ has a light emitting function.

In addition, the supporting member 20 may further have a hole 74, and the optical signal S output by the optical transmitter 36 is received by the optical receiver 38 through the hole 74. Furthermore, the first axle half 62 may have a first wheel wall 76 perpendicular to the axial direction D, and the second axle half 64 may have a second wheel wall 78 perpendicular to the axial direction D. The first light guide surface 68 can be an inner surface of the first wheel wall 76, and the second light guide surface 70 can be an inner surface of the second wheel wall 78. The first wheel wall 76 may further extend beyond a pivot 80, and a ratchet 82 may be disposed on the pivot 80. The second wheel wall 78 may extend through a shaft frame 86 having a through hole 84. First and

second wheel walls

76, 78 are adapted to grip the sides of roller member 66 and are rotatably mounted to support member 20 by pivot 80 and/or axle frame 86. The ratchet 82 can be added with an adjusting element for switching the rolling mode and the operation feeling of the roller module 14. The light emitting element 72 can enter the hollow interior of the roller member 66 via the through hole 84.

The shading element 16 of the mouse wheel device 10 "may be formed directly on the wheel surface, side surface and/or inside of the transparent roller member 66; as shown in fig. 22 to 24, the roller member 66 has the light shielding member 16 on both the wheel surface and the side surface. The shading area 32 of the shading element 16 may be formed by a shading ink layer or an opaque laser engraving modified layer, and is formed on the roller member 66 made of a transparent material, so that a partial area of the transparent roller member 66 can achieve the purpose of shading. The light-transmitting region 34 of the shading element 16 is the other region of the transparent roller member 66 that is not the shading region 32.

Alternatively, the roller module 14 "may further include a roller skin 88 disposed on a circumferential groove 90 formed on the tread of the roller member 66. The roller shoes 88 may have elasticity to match the axial clamping force of the first half axle 62 and the second half axle 64 to the roller member 66, so as to provide a radial tightening force to the roller member 66; alternatively, different microstructures or surface treatments on the roller shoes 88 can be used to provide different user finger feel or friction differences for the same common roller member 66. Preferably, the width W1 of roller skin 88 is less than the width W2 of roller member 66, meaning that roller member 66 partially covers roller skin 88 with circumferential groove 90 such that the outer surface of roller skin 88 is aligned with the outer edge of roller member 66. If the roller module 14 "has the roller leather 88 installed in the annular groove 90 of the roller member 66, the light shielding element 16 of the mouse roller device 10" can be directly formed on the surface, side surface and/or inside of the roller member 66, or can be formed in the annular groove 90; in this embodiment, the light-shielding region 32 of the light-shielding element 16 can be formed by a light-shielding ink layer or an opaque laser engraving altered layer.

In the third embodiment, the arrangement angle of the light emitting element 72 is not limited to the aspect shown in fig. 22 to 24, and the tilt angle can be adjusted according to the position of the mouse wheel device 10 ″ on the housing 2 of the mouse 1. Referring to fig. 23 and 25, fig. 25 is a schematic view of a mouse wheel device 10 ″ according to a third embodiment of the present invention in another variation. In the embodiment shown in fig. 23, the normal vector of the plane of the upper surface of the light-emitting element 72 is directed upward, i.e., the illumination light provided by the light-emitting element 72 is directed directly above the roller member 66. In the embodiment shown in fig. 25, the normal plane vector of the upper surface of the light-emitting element 72 is inclined at an angle (inclined to the left in the drawing plane), so that the mouse wheel device 10 ″ is exposed from the inclined opening of the front half section of the housing 2, in other words, the normal plane vector of the upper surface (light-emitting surface) of the light-emitting element 72 is perpendicular to the inclined opening of the housing 2, so that the illumination light provided by the light-emitting element 72 preferably passes through the inclined opening of the housing 2 directly via the roller member 66 or its side edge, and the area of the roller member 66 protruding out of the housing 2 can provide a better light-emitting effect. It should be noted that the inclination direction and the angle of the light emitting element 72 are not limited to the aspect shown in fig. 25, and may be determined according to the design requirement. In addition, although not shown, the light shielding element 16 may be a separate opaque sheet attached to one side of the roller member 66 to rotate therewith. Generally, the first and second half-

axles

62 and 64 and the roller 66 without the hollowed-out area cannot be used as a grating structure, and particularly, the hollow axle frame 86 is required to be used for disposing the light-emitting element 72. In this embodiment, the light shielding element 16 is directly formed on the wheel surface, the side surface and/or the interior of the transparent roller member 66, so that the optical signal S projected by the optical transmitter 36 can pass through the transparent roller member 66 having the light shielding element 16 and be received by the optical receiver 38, and thus the roller module 14 ″ lacking the hollow area can also be combined with the light shielding element 16 as a grating structure. Furthermore, in addition to being a grating structure for shielding the optical signal S, the light shielding element 16 can rotate with the roller member 66, and intermittently shields the illumination light passing through the roller member 66 through the light shielding region 32 formed on the wheel surface, the side surface and/or the inside of the transparent roller member 66, and simultaneously provides an intermittent illumination light effect to the roller member 66.

In summary, the wheel shaft or the wheel member of the mouse wheel device of the present invention is provided with the low-cost light-shielding element to form the light-shielding area and the light-transmitting area arranged in a staggered manner for intermittently shielding the detection light path of the light detection module to obtain the rotation information of the wheel module and the input command represented by the rotation information. The shading area and the light transmitting area of the shading element can provide various implementation modes according to whether the outer ring area and the inner ring area are matched, and the material and the manufacturing mode of the shading area can be correspondingly changed according to the position. Therefore, the shape and position of the shading element can be modified according to different requirements, thereby not only providing customized service with better elastic grating structure, but also enabling the high-cost wheel shaft to be shared by the mice with different functional types.

The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims.
