Description

Coding module for vernier control device

The utility model relates to an encoding module of a cursor control device.

The cursor control device is an indispensable peripheral device in the Windows operating system. With the different types of Windows application software, the market also provides cursor control devices with different structures, such as mouse, trackball, touch panel, electromagnetic digital board, joystick etc., to meet the needs of cursor input of various application software. Of course, different types of cursor control devices have different structures for generating cursor control signals.

As far as the mouse is concerned, the most common mouse at present is a two-dimensional mouse. The cursor control method is to use the ball to drive the two sets of grating wheels to rotate, so that the light emitted by the two light-emitting diodes has a light-shielding/light-transmitting effect, and passes through the two grating wheels. The light rays are respectively received by the two phototransistors to generate voltage signals, and the voltage signals can be processed to generate signals for controlling the movement of the cursor.

With the increase of types of application software, there is a trend that two-dimensional mice are not enough for use, so three-dimensional or more three-dimensional mice are produced. Of course, when the third-dimensional operation structure of the mouse is added, how to provide a simplified and easy-to-manipulate cursor signal generating device as a third-dimensional signal generating device becomes an important issue.

Therefore, the purpose of this utility model is to provide a simplified coding module of a cursor control device, which can be used as a coding module of a three-dimensional mouse.
