Description

The literal keyboard with key supporting of imitative graphics

Technical field:

The utility model relates to a kind of computer keyboard, relates in particular to a kind of literal keyboard with key supporting of imitative graphics, belongs to the mechanical part technical field.

Background technology:

Along with development of computer with popularize, also obtain general approval as the keyboard of literal input and used widely.Existing English computer keyboard, the enter key on the keyboard is from left to right transversely arranged in alignment, then crosses one another and not point-blank from vertically seeing.When using keyboard to carry out the literal input, must remember the position of each key, knock key from top to bottom with finger, not only keystroke wants accurately also must have certain dynamics to work efficiently.For languages such as English, this input method is very directly perceived effectively, also grasps easily, but need the very complicated input method of a cover for the Chinese character of Chinese characters.At present a lot of embodiments are being arranged aspect the input coding of Chinese character, but its basic premise promptly uses never what variation on the general computer QWERTY keyboard this point.This is a very big obstacle to begining to learn the Chinese character importer, because the first step will be learnt the fingering of computer QWERTY keyboard, the input coding that Chinese character also will be learnt and learn by heart to second step.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art and actual needs, and a kind of literal keyboard with key supporting of imitative graphics is provided, and makes it simple in structure, and is not only general with existing English computer keyboard, also increases the Chinese character hand-written input function, uses more convenient.

For realizing such purpose, in the technical solution of the utility model, from with the diverse design angle of existing keyboard, by arrangement architecture that changes keyboard and the design that improves keycap, mix the input coding for Chinese character program that is installed in advance accordingly in the computer, can import Chinese character at an easy rate.

Keyboard essential characteristic of the present utility model is to be arranged in square formation and to be constituted by each letter key, function key and enter key etc., on the keyboard that is carved with A, B, C, D, E～Z, all English alphabet keys are arranged in neat square matrix-shaped, be that these keys are at horizontal stroke, perpendicular, tiltedly all in alignment on (miter angle) direction.The key cap surface of each key becomes slick and sly convex slope shape, and finger or nib can be erected along horizontal stroke, and tilted direction comes back to slide at an easy rate on adjacent keycap.Each key below is provided with spring or resilient material, the setting of its recuperability than common computor-keyboard slightly a little less than.

When finger successively when streak on the surface of each key, the keycap of convex slope shape can resolve into the power of horizontal cross and downward power longitudinally with the acting force of the finger that is subjected to, and this longitudinally power each key can be pressed successively just, pairing letter is input to computer continuously.Install literal input coding program in the computer in advance, when the sequence of English alphabet that meets this coded program and numeral etc. was transfused on by keyboard, the literal of corresponding this English alphabet and Serial No. promptly was revealed or is transfused to.

Be the versatility of maintenance with existing computor-keyboard, the utility model is being carved with English alphabet, on the general computer QWERTY keyboard of digital and all kinds of marks, on original basis that puts in order of encumbrance keyboard and English alphabet keys, it is square matrix-shaped integral body to be lined up all key in the vertical direction alignment, promptly from horizontal stroke, perpendicular, tiltedly these keys of (miter angle) direction all point-blank.

The utility model is simple in structure, and is easy to operate, can with literal such as Chinese character as picture shape import, as writing, and need not go to remember where each English alphabet keys is with finger.Simultaneously, run into the touch system fingering that to use QWERTY keyboard when beating English again, make several input methods of the old and new on keyboard, can obtain performance.

Description of drawings and embodiment:

For understanding the technical solution of the utility model better, be further described below in conjunction with accompanying drawing.

Fig. 1 is the basic square formation structural representation of the utility model keyboard.

Fig. 2 is the sectional schematic diagram of first row's key among Fig. 1.

Fig. 3 is the square formation structural representation of the utility model practical application embodiment.

As shown in Figure 1, in the keyboard of the present utility model, each English alphabet keys, function key and enter key etc. are arranged in square formation, and perpendicular from horizontal stroke, tiltedly these keys of (miter angle) direction all point-blank.

As shown in Figure 2, the shape of the keycap 1 of each key is different from the keycap on the existing computor-keyboard, and the surface of keycap 1 becomes slick and sly convex slope shape, is provided with resilient material 3 in the keyway 2 under the keycap.

When using a finger (such as using forefinger) successively when streak on the surface of each key of abcde, the keycap of convex slope shape can resolve into the power of horizontal cross and downward power longitudinally with the acting force of the finger that is subjected to.And this longitudinally power each key can be pressed successively just, reach English sequence with these five letters of abcde and be input to purpose in the computer.From the angle of figure, " abcde " just in time is the stroke of a horizontal stroke, as " one " word.If in the literal code program in computer, " abcde " sequence corresponding to " one " word, just can automatically be demonstrated " one " word so on computer screen.

Same principle, in Fig. 1, after keying in " CHMRWVLPNT ", its pairing " little " word just shows on computer screen automatically sliding with finger on the computor-keyboard successively when imitation " little " font.

Should illustrate that a bit what make each key maintenance ortho states (static position when promptly not being pressed) is the spring or the resilient material of each key below, the key that these springs or resilient material are pressed is to recover the recuperability of ortho states.In keyboard of the present utility model the inside if this recuperability be set than common computor-keyboard a little less than some (roughly being set in 20 grams to the scope between 40 grams), utilization vertical component down overcomes the opposing of the recuperability of spring or resilient material in the time of just can making finger or nib etc. slip over key cap surface, the signal of this key is input in the computer, the keyboard key property of guaranteeing to import continuously.

Because keyboard features of the present utility model are that all keys are arranged in horizontal stroke, perpendicular, tiltedly (miter angle) direction is all straight square matrix-shaped, and the some of them key as point, has just been constituted a figure after by the order of finger keystroke these points being coupled together again.When the font of this figure and literal is same or similar, in fact can regard input behavior as to this literal by finger or the sequence of operations carried out of nib.Because the English alphabet sequence of being imported can be set up a kind of corresponding relation with this literal, this corresponding relation is encoded exactly.As long as be put in the computer loading routine after according to the custom of common people's writing Chinese characters coding being finished, just can allow user, particularly beginner and the elderly carry out literal like a cork and import.

Chinese Chinese character mainly be by point, horizontal line, vertical line and oblique line in the plane combination and constitute, have very strong graphic characteristics.And square formation keyboard of the present utility model can allow the graphic characteristics of Chinese character fully show, and can be applicable to the keyboard input to Chinese character.

Keyboard shown in the accompanying drawing 3 is to be arranged in square matrix-shaped structure with each numerical key and English alphabet keys, the features of shape of each key and using method and at accompanying drawing 1 on it, and the structure mechanism shown on the accompanying drawing 2 is identical.The number of the key that it is arranged and order be with general English computer keyboard basically identical, just the key on each horizontally-arranged alignd in the vertical and two square matrix-shaped general layouts about making it to be arranged in.So, the keyboard shown in the accompanying drawing 3 has just had an important feature, and that common touch system fingering is also applicable in the same old way.Do not become because the relative position of each key, do not influence the touch system fingering that people are familiar with,, increased the new function of a similar handwriting input again so it both can equally use with general now English computer keyboard.Input to Chinese character and graphic sign etc. provides more, and approach is particularly useful for beginner and the elderly's use more easily.

Use the keyboard shown in the accompanying drawing 3, for input radicals by which characters are arranged in traditional Chinese dictionaries radical earlier again this function of Chinese character retrieval be very favourable.The stroke of radicals by which characters are arranged in traditional Chinese dictionaries radical is less, and input is got up fast.The complicated Chinese character that stroke number is many can be retrieved the mode of selecting and import by importing the radicals by which characters are arranged in traditional Chinese dictionaries radical earlier again.
