[0029] Please refer to Figures 1 to 5. Figure 1 A schematic diagram of a mouse 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 An exploded view of the mouse 100, Figure 3 Draw Figure 1 A top view of the mouse 100, Figure 4 Draw Figure 3 A cross-sectional view of the mouse 100 along direction 4-4', and Figure 5 Draw Figure 2 Schematic diagram of the roller module 120.

[0030] like Figures 1 to 4 As shown, the mouse 100 includes a housing 110A, a housing 110B, a roller module 120, a light source 130 and a circuit board 140. The housing 110A has an opening 110A1, the housing 110B has an opening 110B1, the roller module 120 is exposed from the openings 110A1 and 110B1 and has an axis portion 1211 and a light incident surface 1211s, and the axis portion 1211 is substantially perpendicular to the light incident surface 1211s. The light source 130 is used to emit a light L1 toward the light incident surface 1211s. In this way, the light L1 can be transmitted inside the roller module 120, and part of the light L1 can be emitted from a portion of the roller module 120, so that the roller module 120 becomes a light-emitting roller module.

[0031] like Figure 4 As shown, the wheel module 120 can be configured in an electronic device, wherein the electronic device is, for example, a mouse, a keyboard, a home appliance or other electronic products that require an input device. The wheel module 120 includes a light guide wheel 121, at least one counterweight (for example, a first counterweight 122A and a second counterweight 122B) and a cover 123. The counterweight is configured on the light guide wheel 121. Due to the counterweight, the wheel module 120 is not too light and can be applied to a shuttle wheel mouse (if the rotation speed of the wheel module is to be fast, it needs to have a certain weight).

[0032] like Figure 4 As shown, in this embodiment, the light guide wheel 121 is, for example, a light-transmitting light guide wheel. In one embodiment, at least a portion of the light guide wheel 121 is light-transmitting. In terms of material, the light guide wheel 121 can be made of plastic. In terms of manufacturing process, the light guide wheel 121 can be formed by, for example, plastic injection molding technology.

[0033] like Figure 4 As shown, the light guide wheel 121 includes the aforementioned axial portion 1211, the peripheral portion 1212, at least one pressing portion 1213 and the lateral portion 1214. In one embodiment, at least two of the axial portion 1211, the peripheral portion 1212, the pressing portion 1213 and the lateral portion 1214 are, for example, integrally formed structures. The light guide wheel 121 is disposed on the housing with the axial portion 1211, and can rotate relative to the center line of the axial portion 1211. A portion of the axial portion 1211 can protrude relative to the light incident surface 1211s. The peripheral portion 1212 surrounds the axial portion 1211. The light guide wheel 121 has a first groove 1211r1 and a second groove 1211r2, and the first groove 1211r1 and the second groove 1211r2 are recessed relative to the light incident surface 1211s of the axial portion 1211. In this embodiment, the light incident surface 1211s is a side surface of the light guide wheel 121. The pressing portion 1213 may be disposed on the inner wall of the peripheral portion 1212 . The pressing portion 1213 may press against the first counterweight 122A to fix the relative position between the first counterweight 122A and the light guide wheel 121 .

[0034] like Figure 5As shown, the first counterweight 122A is disposed in the first groove 1211r1, and the second counterweight 122B is disposed in the second groove 1211r2. After the first counterweight 122A is disposed in the first groove 1211r1 of the light guide wheel 121, the pressing portion 1213 presses on the first counterweight 122A to fix the relative position of the first counterweight 122A and the light guide wheel 121. The second counterweight 122B is disposed in the second groove 1211r2 and is tightly fitted to the shaft portion 1211. For example, the outer peripheral surface of the shaft portion 1211 has a taper, and the second counterweight 122B can be tightly fitted to the shaft portion 1211 through the taper. In terms of material, the counterweight can be made of metal, but this is not intended to limit the embodiments of the present invention.

[0035] like Figure 4 As shown, the lateral portion 1214 connects the peripheral portion 1212 and the axial portion 1211, the peripheral portion 1212 surrounds the axial portion 1211, and the peripheral portion 1212 has a first light-guiding peripheral surface 1212s1, a second light-guiding peripheral surface 1212s2, a first light-emitting surface 1212s3, and a second light-emitting surface 1212s4, wherein the first light-guiding peripheral surface 1212s1 is directly or indirectly adjacent to the first light-emitting surface 1212s3, and the second light-guiding peripheral surface 1212s2 is directly or indirectly adjacent to the second light-emitting surface 1212s4. The first light-guiding peripheral surface 1212s1 can guide a portion of the light L1 incident thereon to the second light-guiding peripheral surface 1212s2. By properly designing the angle of the first light guide peripheral surface 1212s1 and / or the angle A1 between the first light guide peripheral surface 1212s1 and the second light guide peripheral surface 1212s2, the difference in light intensity incident on the first light guide peripheral surface 1212s1 and the second light guide peripheral surface 1212s2 can be minimized as much as possible (averaging the light output on both sides). Angle A1 can be an acute angle, an obtuse angle, a right angle, or other values ​​other than 180 degrees.

[0036] In one embodiment, a first obtuse angle A2 is formed between the first light emitting surface 1212s3 and the first light guiding peripheral surface 1212s1, and a second obtuse angle A3 is formed between the second light emitting surface 1212s4 and the second light guiding peripheral surface 1212s2. In this way, the first light guiding peripheral surface 1212s1 can guide the light L1 to the first light emitting surface 1212s3 for light emission, and the second light guiding peripheral surface 1212s2 can guide the light L1 to the second light emitting surface 1212s4 for light emission. In one embodiment, the first light guiding peripheral surface 1212s1 and / or the second light guiding peripheral surface 1212s2 can have a microstructure layer (e.g., a concave-convex particle surface), which can scatter the incident light L1 to achieve a uniform light effect. The microstructure layer, for example, includes a plurality of concave / convex portions. In terms of manufacturing process, the microstructure layer can be formed integrally with the light guide wheel 121 in the same manufacturing process (for example, in injection molding, the mold can have a structure corresponding to the microstructure layer).

[0037] like Figure 4and 5 As shown, the light guide wheel 121 further has a light guide surface 121s, and an acute angle A4 is formed between the light guide surface 121s and the axial portion 1211. The light guide surface 121s can guide the light L1 to the first light guide peripheral surface 1212s1. After the light L1 is guided to the first light guide peripheral surface 1212s1, the first light guide peripheral surface 1212s1 produces the aforementioned technical effect of averaging the light output on both sides. In addition, although not shown, the light guide surface 121s has a microstructure layer (for example, a concave-convex particle surface), which can scatter the incident light L1 to achieve a uniform light effect. The microstructure layer, for example, includes a plurality of concave / convex portions. In terms of the process, the microstructure layer can be formed integrally with the light guide wheel 121 in the same process (for example, in injection molding, the injection molding mold can have a structure corresponding to the microstructure layer).

[0038] According to the simulation experiment results, the first light output brightness of the light L1 from the first light guide peripheral surface 1212s1 of the light guide wheel 121 is, for example, 85 nits, and the second light output brightness from the second light guide peripheral surface 1212s2 is, for example, 71 nits, wherein the ratio of the second light output brightness to the first light output brightness is 1:0.835 (close to 1:1). In contrast, for the light guide wheel 121 in which the light guide surface 121s is omitted, the first light output brightness of the light L1 from the first light guide peripheral surface 1212s1 of the light guide wheel 121 is, for example, 85 nits, and the second light output brightness from the second light guide peripheral surface 1212s2 is, for example, 28 nits, wherein the ratio of the second light output brightness to the first light output brightness is 1:0.33 (far from 1:1).

[0039] like Figure 4 As shown, the light guide wheel 121 further has a peripheral surface, which has at least a first light guide peripheral surface 1212s1 and a second light guide peripheral surface 1212s2. The covering member 123 covers the peripheral surface of the light guide wheel 121. The covering member 123 is, for example, light-transmitting or light-blocking (opaque). The material of the covering member 123 is, for example, plastic or rubber. The covering member 123 has, for example, a rough surface, which can provide the user with a rough (frictional) feel. Due to the design of the covering member 123, the user can rotate the roller module 120 faster.

[0040] like Figure 4 As shown, the light source 130 can be disposed on and electrically connected to the circuit board 140. The light source 130 has a light emitting surface 130s facing the roller module 120 to emit light L1 laterally to the roller module 120. In addition, the light source 130 is, for example, a light emitting diode or other types of light sources.

[0041] Please refer to Figure 6, which shows a partial cross-sectional view of a mouse according to another embodiment of the present invention. The mouse 200 includes a housing 110A (not shown), a housing 110B (not shown), a wheel module 120, a light 130 and a circuit board 140. The mouse 200 of the present embodiment includes the same or similar technical features as the aforementioned mouse 100, with at least one difference being that the light source 130 of the mouse 100 is an upward incident light source.

[0042] like Figure 6 As shown, the roller module 120 includes an axis portion 1211 and a peripheral light incident surface, and the peripheral light incident surface surrounds the axis portion 1211. The light source 130 is used to emit light L1 toward the peripheral light incident surface. For example, the roller module 120 can be configured in an electronic device, wherein the electronic device is, for example, a mouse, a keyboard, a home appliance or other electronic products that require an input device. The roller module 120 includes a light guide wheel 121, at least one counterweight (for example, a first counterweight 122A and a second counterweight 122B) and a covering 123. The covering 123 has the aforementioned peripheral light incident surface 123s. The light emitting surface of the light source 130 is opposite to the peripheral light incident surface 123s, so as to emit light L1 through the peripheral light incident surface 123s to be incident on the covering 123 and the light guide wheel 121. In the present embodiment, the covering 123 is a light-transmitting covering. In another embodiment, the roller module 120 may omit the covering member 123 . In this example, the light guiding peripheral surface of the light guide wheel 121 (eg, the first light guiding peripheral surface 1212s1 and the second light guiding peripheral surface 1212s2 ) may serve as the peripheral light incident surface.

[0043] In summary, the scroll wheel module and the mouse using the same, the scroll wheel module includes a light guide wheel and at least one counterweight, and the counterweight is arranged on the light guide wheel. Due to the counterweight, the scroll wheel module is not too light and can be applied to a shuttle scroll wheel mouse (if the rotation speed of the scroll wheel module is to be fast, it needs to have a certain weight). In one embodiment, the light guide wheel is, for example, a light-transmitting wheel, and light can be incident from the light incident surface of the scroll wheel module and guided to the light exiting surface of the light guide wheel to emit light, so that the scroll wheel module becomes a light-emitting scroll wheel module. In one embodiment, the light guide wheel has two light guide peripheral surfaces and two corresponding light exiting surfaces, wherein the two light guide peripheral surfaces can respectively guide light to the two light exiting surfaces, so that the two sides of the light guide wheel emit light. In another embodiment, one of the two light guide peripheral surfaces can be guided to the other of the two light guide peripheral surfaces to average the light intensity on the two sides of the light guide wheel. In other embodiments, the light guide wheel further has a light guide surface, and the light guide surface can guide light to one of the two light guide peripheral surfaces. In one embodiment, the light incident surface is, for example, a side surface or a peripheral surface of a light guide wheel of the roller module.
