The present invention can enable the mouse to realize remote operation, and has the characteristics of no cable wire limitation, long distance remote control (more than 8m), sensitive operation, good compatibility of software, strong anti-interference ability, no direction limitation, high function/price ratio, etc.
Description
The present invention relates to the computer entry device Genius mouse, particularly the three key mouse device.
Existing computing machine three key mouse device all is to be connected with computing machine by a cable, to finish the transmission of mouse control signal, realizes the operation that the series of computation machine instructs thereby reach with Genius mouse.Obviously there are two point defects in this Genius mouse: 1, be subjected to the restriction of cable, can not carry out remote-controlled operation; 2, the long-time swinging operation of cable, be easy to the fracture and damage.
The objective of the invention is to design a kind of infrared remote mouse with three keys, make Genius mouse can realize straighforward operation.
The present invention includes two parts of infrared remote control mouse transmitter and infrared remote control mouse receiver (following transmitter and the receiver of also being called for short).The said infrared remote control mouse of the present invention transmitter is made up of optical encoding control circuit, microcontroller circuit, infrared modulation radiating circuit, power circuit; Infrared remote control mouse receiver is made up of infrared receiving demodulation circuit, buffer circuit, line driver circuit.Its principle is an infrared remote control mouse transmitter with the Genius mouse operation signal behind optical encoding control circuit coding, sends into microcontroller circuit and handles, again through the modulation of infrared modulation radiating circuit, emission; Infrared remote control mouse receiver is received the signal of infrared remote control mouse transmitter emission and is carried out demodulation by infrared receiving demodulation circuit, behind buffer circuit, input to line driver circuit and carry out conversion of signals, input to the computer mouse interface again, realize the straighforward operation of computer mouse.
In order to use infrared remote control mouse transmitter can be in off working state when not operating, to reduce the consumption of its power supply, the present invention also can be provided with power switch, working station indicator in infrared remote control mouse transmitter circuit.
The present invention is compatible triple bond pattern (PC pattern) infrared remote-controlled mouse, both can make trace ball formula infrared remote mouse with three keys, also can make photoelectricity mechanical type infrared remote mouse with three keys or optical profile type infrared remote mouse with three keys.Infrared remote receiver of the present invention also can directly place computer-internal.
The present invention has the following advantages: not limited by cable, (greater than 8 meters) carry out the operation of mouse at a distance; 2, manual dexterity, essentially no directivity; 3, function/price is than high.
