mouse
Introduction:
The mouse is a very common and commonly used computer input device. It can position the cursor on the current screen through buttons and wheel devices, and operate the screen elements that the cursor passes through. The ancestor of the mouse appeared in 1968. Douglas Englebart, an American scientist, made the first mouse in California, which was named after it looked like a mouse. The standard name of "rat" should be "rat". The use of the mouse is to make the operation of the computer easier, not the tedious instructions of the keyboard.
Precautions:
(1) The light-emitting diode and the light-sensitive diode in the optical mouse are accessories that are afraid of vibration. Pay attention to avoid pulling the mouse line when using.
(2) Pay attention to keep the photosensitive plate clean and in a good photosensitive state when using, so as to avoid dust adhering to the light-emitting diodes and photosensitive diodes, blocking the reception of light and affecting normal use.
(3) Don't knock the mouse button too hard to avoid knocking the mouse, so as not to damage the elastic switch or other parts.
