Description
Technical field
The utility model belongs to positioning input equipment technical field, more specifically, is related to one kind and is twisted using head
The positioning input device of sensing, it is similar with mouse, it is related to computer, mobile phone, image generation and the positioning of processing unit input.
Background technology
Mouse is a kind of input equipment, and the indicator of calculator display organization coordinate setting in length and breadth, because being similar to mouse
And gain the name " mouse ".American scientist Douglas Engelbart (Douglas Englebart) nineteen sixty-eight is in Jia Lifu
Ni Ya has made first mouse.Mouse is different according to working method, can be divided into：Mechanical mouse, optical machine mouse and photoelectricity mouse
Mark；According to different with the connected mode of computer, wired and wireless mouse can be divided into.
As shown in Fig. 1 (a), mechanical mouse with one can four-way roll colloid bead.This bead can band when rolling
Dynamic a pair of axis of rotation (being respectively X rotating shafts, Y rotating shafts), there is a circular decoding wheel turning the tip of the axis, decoding is taken turns upper attached
There is metallic conduction piece directly to be contacted with brush.When the spindle is rotated, these metallic conduction pieces will contact successively with brush, occur
Two kinds of forms of " on " or "off", the former corresponds to binary number " 1 ", the latter corresponds to binary number " 0 ".Next, these two
Binary signal makees changes in coordinates signal corresponding to dissection process and generation by the special chip delivered inside mouse.As long as mouse exists
Moved in plane, bead will drive axis of rotation, and then the break-make situation of decoding wheel is changed, and it is different to produce one group of group
Coordinate offset amount, be reacted on screen, be exactly that cursor can move with the movement of mouse.
As shown in Fig. 1 (b), optical machine mouse is improved on the basis of Purely mechanical mouse, by introducing optical technology
To improve the positioning precision of mouse.As Purely mechanical mouse, optical machine mouse equally possesses the small spin of a colloid, and even
Then X, Y rotating shaft, except that optical machine mouse there is no circle decoding wheel, instead of be two with grid seam grating codes
Disk, and add light emitting diode and sensitive chip.When mouse moves on the table, spin can drive the two of X, Y rotating shaft
Grating encoder is rotated, and the light that X, Y light emitting diode are sent will be radiated on grating encoder, because grating encoder has grid
Seam, can the detector that is formed in two sensitive chips of transmission grating seam direct irradiation in the light that appropriate opportunity diode emitter goes out
On.If receiving optical signal, sensitive chip will produce " 1 " signal, if without optical signal is received, it is set into signal
“0”.Next, these signals are admitted in special control chip coordinate offset amount corresponding to computing generation, determine that cursor exists
Position on screen.
Optical mouse does not have the design such as traditional spin, rotating shaft, and its critical piece is two light emitting diodes, photosensitive core
Piece, control chip and one carry the reflecting plate of grid (equivalent to special mouse pad).Optical mouse must be anti-during work
Penetrate on plate and move, X light emitting diodes and Y light emitting diodes can launch light respectively and be radiated on reflecting plate, then light meeting
Gone back by baffle reflection, be radiated at after lens assembly transmits on sensitive chip.Sensitive chip converts light signals into pair
It is sent to special disposal in positioning chip after the data signal answered, and then produces X-Y coordinate offset data.
Wireless mouse operation principle is identical with wire mouse, and simply its connected mode uses bluetooth or infrared connection, and does not have
Live wire is directly connected with devices such as computers.
Traditional positioning input device, such as mouse are required for individually carrying, and also have that complicated, power consumption is high and fragile
The problems such as.
