Description

Mouse wheel device and its mouse

The invention provides a mouse wheel device and its mouse, especially a mouse which has a grating effect and does not affect the light emitting function of the wheel.

The scroll wheel module on the top of the mouse is mainly used to control the scrolling of the computer screen. The rotation speed of the scroll wheel operated by the user with fingers is directly related to the scrolling speed of the screen and the range of screens that the user can browse per unit time. The scrolling speed of the scroll wheel is usually detected by an encoder. The most widely used on the mouse is the mechanical encoder. Compared with the grating encoder, the mechanical encoder has a simple structure, easy master control programming and a mechanical scale feel. The mechanical encoder has a turntable. When the mouse wheel rotates to drive the turntable of the mechanical encoder, the plurality of contacts on the turntable and the fixed contacts on the base are in electrical contact with each other, thereby generating intermittent conduction signals. The grating encoder uses a set of optical transceiver modules to be installed on both sides of the grating structure. When the wheel is rolling, the grating structure blocks and conducts the optical signal, which can be used to detect the rotation speed of the mouse wheel. The optical receiver and optical transmitter of the traditional optical transceiver module are respectively arranged on two opposite sides of the roller. The optical signal output by the optical transmitter passes through the roller and is received by the optical receiver. Therefore, the roller needs to be designed with a corresponding hollow structure to allow light Signal crossing. The roller can be made of a transparent material, and a light-emitting unit is arranged inside it. The illumination light of the light-emitting unit is reflected by the inner wall of the roller so that the roller can emit light; however, the hollow structure of the roller will reduce the reflection efficiency and destroy the luminous effect of the roller.
