Description

A computer input device

technical field

The utility model relates to an input device, in particular to a computer input device with control signals through rotation.

Background technique

A computer input device (Pointing Device) generally refers to a computer system (such as a personal computer, a notebook computer or a personal digital assistant, etc.) that can input a coordinate displacement signal to request the cursor in the computer system to perform an action corresponding to the coordinate position. Or execute the command preset relative to the coordinate position in the application software; there are many types of pointer input devices currently visible, such as mice, trackball devices, touch pads, handwriting pads, joysticks, etc., but in practical applications, the mouse is roughly like the palm of your hand General size, small volume and easy manipulation, it has become a more common computer input device.

In addition, most computer systems or computer software have adopted windowed operation interfaces. When the software window is larger than the display screen, a scroll bar will appear on the right side or below the software window, and the user can move the computer input device so that the pointer is positioned on the scroll bar. position, to control the scroll bar up and down or left and right to move the window; and in order to control the scroll bar more easily, the mouse currently used with the computer system is equipped with a scroll wheel, and the user can also control the scroll bar of the software window through the scroll wheel to Move the software window to the position you want to watch. In order to control the window screen through the scroll wheel, the scroll wheel is set on a rotating shaft. There is a rotary switch at one end of the rotating shaft. The rotary switch can compile the rotating action of the scroll wheel into a control signal to input to the computer system to control the scroll bar action.

Known rotary switch can be seen Chinese patent No. CN99205197, and No. CN99205197 discloses a kind of decoder structure, and wherein this decoder is installed on the roller in a mouse, and this decoder structure is by main The main seat is composed of a base, a casing, a turntable, a brake pad and a guide piece. The main seat is provided with several pins exposed outside the main seat. The pins are also provided with conductors. The turntable is rotatably set in the main seat.
