Input device light-emitting roller assembly

The present invention relates to an input device having a illuminable roller, and more particularly to an input device in which light can be uniformly emitted in all directions of the roller.

The mouse is one of the most common computer peripherals in today's society. The bottom of the mouse is equipped with a sensor to sense the change of the position of the mouse. The top surface of the mouse is provided with two buttons, and the two buttons are provided with a roller. Both the buttons and the scroll wheel are used to input commands to the computer.

Today's users, in addition to pursuing excellent functions, also have certain requirements for the visual effects they can produce. Therefore, some manufacturers have designed a mouse that can be illuminated by a roller, such as the Taiwan Bulletin No. 470910 "Indicator device with illuminating reel roller" invention patent, please refer to FIG. 11, wherein the roller 91 is made of transparent material, and a tapered reflecting surface 92 is disposed coaxially inside the roller 91, and the roller 91 is A light source 93 is disposed on one side, and the light source 93 is located above the pivot 911 of the roller 91, and faces the reflecting surface 92. The reflecting surface 92 reflects the projected light of the light source 93 upward and exits the outside of the roller 91.

However, in the aforementioned prior art mouse, since the light source 93 is located above the pivot 911 of the roller 91, the light source 93 cannot face the axis of the tapered reflecting surface 92, and thus the reflecting surface 92 can only reflect the light source upward. 93 light, it is difficult to evenly reflect the light to other angles, especially the lower half of the roller 91, the light transmission effect is very poor; and when this design is used for the transparent mouse housing, the light source 93 is caused The overall visual effect is not ideal.

In view of the above disadvantages and deficiencies of the prior art, the present invention provides an illuminating roller assembly for an input device, wherein the light source is directly opposite to the axis of the reflecting surface to achieve uniform reflection and light transmission.

In order to achieve the above object, the technical means adopted by the present invention is to design an illumination device assembly for an input device, comprising: a stop portion; an encoder spaced apart from the stop portion; and a roller disposed on the Between the stop portion and the encoder, and the encoder is pivoted, the roller axially recesses a receiving groove, the opening of the receiving groove faces the stopping portion; the roller is a material capable of transmitting light; and a pivoting sleeve The pivoting portion is disposed in the receiving portion of the roller, and the pivoting sleeve is coaxial with the roller; the pivoting sleeve is a material capable of transmitting light; and a reflecting surface is disposed in the pivoting sleeve and located at In the accommodating groove of the roller, the reflecting surface is tapered, and is coaxial with the roller, the cone tip of the reflecting surface faces the stopping portion; a light source is disposed in the pivot sleeve, and faces the cone of the reflecting surface, the light source and The reflecting surface is concentric.

The invention has the advantages that the roller is pivoted with the stopping portion by using a hollow pivot sleeve, so that the light source in the pivot sleeve can be coaxially facing the cone tip of the reflecting surface, and the light of the light source can be reflected. Evenly toward the path The light is reflected upwards in various directions, so that the light can not only project the roller upwards, but also the roller can be emitted laterally and downwardly. The invention can thereby uniformly emit the transparent roller and further improve the texture of the input device.

Further, the light-emitting roller assembly of the input device, wherein the stopping portion comprises two columns and a switch, the switch is disposed between the two columns; the pivoting sleeve is disposed between the two columns and abuts the switch The top surface. After the roller is pressed, the switch can be triggered by the pivot sleeve to achieve the effect of inputting a command on the computer.
