Description
This case is application number: 201010236229.7, the applying date: 2010.7.16, applicant: Chen Hung Optical Science & Technology Co., Ltd, the divisional application of the patent application of denomination of invention " keyboard uses electronic installation and the input method of this keyboard ".
Technical field
The present invention relates to a kind of data input device, particularly relate to a kind of keyboard in conjunction with composite holographic technology Yu touch technology, use the electronic installation of this keyboard and a kind of input method.
Background technology
Nowadays, keyboard is the most common topmost computer entry device, and it is widely used on microcomputer and various terminal unit.QWERTY layout mode is more general keyboard layout common at present, is usually used on desktop computer or notebook computer.Difference according to the key mode of keyboard, it is possible to be divided into four kinds of types: mechanical keyboard, Plastic Diaphragm Type Servomotor keyboard, conductive rubber formula keyboard, contactless electrostatic capacitive keyboard.According to its operation principle, contact can be divided into again and contactless.
It is known that mechanical keyboard is the commitment being commonly used in keyboard development history.The operation principle of the button of this mechanical keyboard is belonging to contact.Each key has 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, both adopts metal material to make, such as copper.When user's key tap, two metal parts contact with each other, and thus input an opening and export signal.In contrast, when user unclamps button, by two metal parts separately, return to the state of closedown.This mechanical keyboard has the advantages such as manufacturing process is simple and easy to maintenance, but its feel is poor, and noise is big, easy to wear.Additionally, major part mechanical keyboard adopts copper sheet spring as elastomeric material, during use, copper sheet easily follows the string after backfin, uses time one long fault rate to raise.The operation principle of Plastic Diaphragm Type Servomotor keyboard and conductive rubber formula keyboard is belonging to contact too, and its press-key structure is similar to aforesaid mechanical keyboard.Each key has the metal parts that corresponding two metal materials are made, for instance scale copper.When both parts contacts with each other, button is just in opening.In this case, scale copper by the pressure born and produces abrasion.After a period of time, scale copper is likely to be broken, and even results in the inefficacy of whole keyboard.
Therefore, the birth of capacitance keyboard solves the problems referred to above.The operation principle of this capacitance keyboard is belonging to non-contacting.Each button includes two independent electrodes.When user pushes button, two interelectrode distances will reduce, electric capacity between the two and correspondingly change.Due to the change of electric capacity, thus exciting the transient current of keyboard.When transient current exceedes certain value, capacitance keyboard just exports the signal of telecommunication.The operation principle of this capacitance keyboard is to utilize the change of electrode distance thus causing capacitance variations.Owing to capacitance keyboard is contactless, its wear rate is minimum negligible, and has that noise is little, the feature of good hand touch, but its manufacturing process is complex.
Above-mentioned keyboard can be collectively referred to as physical keyboard, multiple one keys form an integral keyboard, owing to the gap existed between keyboard is relatively larger, it is easy to shelter evil people and countenance evil practices, it is difficult to cleaning, causes button malfunction.It addition, for meeting the demand of various countries' user different language, on button, generally stamp the character code of required national language and symbol in order to labelling.Current keyboard dealer adopts laser engraving mode mostly, first produces QWERTY keyboard, then according to the different upper corresponding character codes of demands marking and symbol, once after the character code of keyboard and symbol stamp, cannot change.When occurring that marking mistake or mistake cannot use when transporting, then need to scrap or cover with paster or do replacing etc. to process, suitable cost of idleness.And, when user needs to switch between various countries' language, conventional entity keyboard cannot change required keyboard interface as required.
In recent years, clipboard is better than conventional keyboard input because of convenience, is increasingly becoming another kind of popular input equipment, but mostly adopts writing pencil input because of it, if writing pencil is lost will cause that whole handwriting pad cannot use.Additionally, clipboard generally all uses with aforementioned keyboard simultaneously.In this case, the parts of the two independence will occupy more space in working space.
Along with the development of electronic technology, increasing user has portability, convenience and multi-functional electronic installation in pursuit, it is necessary to a kind of new input tool solves the problem existing for aforementioned entities keyboard and handwriting pad and defect.Therefore, a kind of input equipment integrating keyboard, handwriting pad and mouse is Worth Expecting.
