Description
[technical field]
The utility model relates to a kind of data input device, particularly relate to a kind of in conjunction with composite holographic technology and touch technology keyboard and use the electronic installation of this keyboard.
[background technology]
Nowadays, keyboard is the most common topmost computer entry device, and it is widely used on microcomputer and the various terminal device.The QWERTY layout type is present common more general keyboard layout, is usually used on desktop computer or the notebook computer.Difference according to the key mode of keyboard can be divided into four types: mechanical type keyboard, Plastic Diaphragm Type Servomotor keyboard, conductive rubber formula keyboard, contactless electrostatic capacitive keyboard.According to its principle of work, can be divided into contact and contactless again.
As everyone knows, the mechanical type keyboard is the commitment that generally uses in the keyboard development history.The principle of work of the button of this mechanical type keyboard belongs to contact.Each key has the built-in metal part as contact point.This metal parts generally includes two independent parts: the hard contact of a flexible member and a correspondence, the both adopts metal material to make, as copper.When user's key tap, two metal parts are in contact with one another, and import an opening and output signal thus.In contrast, when the user unclamps button, with two metal parts separately, get back to closing state.This mechanical type keyboard has advantages such as manufacturing process is simple and easy to maintenance, but its feel is poor, and noise is big, and is easy to wear.In addition, most of mechanical keyboard adopts the copper sheet spring as resilient material, and copper sheet easily follows the string after backfin during use, and service time one, long failure rate raise.The principle of work of Plastic Diaphragm Type Servomotor keyboard and conductive rubber formula keyboard belongs to contact too, and its press-key structure is similar to aforesaid mechanical type keyboard.Each key all has corresponding two metal parts that metal material is made, for example scale coppers.When these two parts were in contact with one another, button just was opening.In this case, scale copper is with the pressure and the generation wearing and tearing of bearing.After a period of time, scale copper may be damaged, even causes the inefficacy of whole keyboard.
Therefore, the birth of capacitance keyboard has solved the problems referred to above.The principle of work of this capacitance keyboard is to belong to non-contacting.Each button comprises two independently electrodes.When the user pushes button, two interelectrode distances will reduce, electric capacity between the two and correspondingly changing.Because changes in capacitance, thereby excited the momentary current of keyboard.When momentary current surpassed certain value, capacitance keyboard was just exported electric signal.Thereby the principle of work of this capacitance keyboard is to utilize the variation of electrode distance to cause capacitance variations.Because capacitance keyboard is contactless, its rate of wear is minimum ignores, and has that noise is little, the characteristics of good hand touch, but its manufacturing process is comparatively complicated.
Above-mentioned keyboard can be referred to as physical keyboard, forms an integral keyboard by a plurality of one keys, because the gap that exists between the keyboard is bigger, shelters evil people and countenance evil practices easily, is difficult to cleaning, causes button malfunctioning.In addition, for satisfying the demand of various countries user different language, on button, stamp the character code of required national language and symbol usually in order to mark.At present the keyboard dealer adopts the laser engraving mode mostly, produces QWERTY keyboard earlier, again according to corresponding character code and symbol in the different demand mint-marks, in case after the character code of keyboard and symbol stamp then can't change.When occurring to use when mint-mark mistake or mistake are transported, then need to scrap or cover or do processing such as replacings, suitable cost of idleness with paster.And, need between various countries' language, switch as the user, traditional physical keyboard can't be changed required keyboard interface as required.
In recent years, clipboard also becomes another kind of popular input media gradually because of convenience is better than the conventional keyboard input, but because of it adopts the writing pencil input mostly, will cause whole handwriting pad to use if writing pencil is lost.In addition, clipboard all uses with aforementioned keyboard usually simultaneously.In this case, these two independently parts will occupy more space in the workplace.
Along with development of electronic technology, increasing user has portability in pursuit, and convenience and multi-functional electronic installation need a kind of new input tool to solve aforementioned physical keyboard and existing problem of handwriting pad and defective.Therefore, a kind of input equipment that integrates keyboard, handwriting pad and mouse is to be worth expectation.
