Description

Hand-held type track ball mouse

Technical Field

The utility model relates to the technical field of electronic equipment, which is mainly applied to a mobile phone or a tablet computer and can also be applied to a computer; in particular to a hand-held trackball mouse.

Background

The Mouse, an input device of computer, also an indicator for positioning the longitudinal and transverse coordinates of computer display system, is named as Mouse (gang Tai as Mouse), its standard name should be "Mouse", English name "Mouse", the use of Mouse is to make the operation of computer more simple and quick, to replace the tedious instruction of keyboard. The conventional mouse may be classified into a mechanical mouse and an optical mouse according to its operation principle. The mechanical mouse mainly comprises a rolling ball, a roller and a grating signal sensor. When a mouse is dragged, the rolling ball is driven to rotate, the rolling ball drives the roller to rotate, photoelectric pulse signals generated by a grating signal sensor arranged at the end part of the roller reflect the displacement change of the mouse in the vertical and horizontal directions, and the movement of a cursor arrow on a screen is controlled through the processing and conversion of a computer program; the photoelectric mouse converts displacement signals into electric pulse signals by detecting the displacement of the mouse and controls the movement of a cursor arrow on a screen by processing and converting a program. The photoelectric mouse replaces the rolling ball with a photoelectric sensor. Such sensors require a specially made backing plate with a stripe or dot pattern to be used in conjunction. When the mouse is used, the mouse needs to move on a relatively fixed and flat working table surface to realize the function, and once the mouse leaves the working table surface, the mouse cannot be used basically. However, in many cases, people need to operate the computer when leaving the desktop, such as when performing PPT demonstration, or when operating a home high-definition cinema built by the computer. At this time, the conventional mouse cannot satisfy the demand.

Therefore, there is a need to provide a new handheld trackball mouse to solve the above technical problems.
