Abstract
The special auxiliary keyboard of a kind of numeral input, be provided with and comprise numerical key 1-9, numerical key 0, enter key, backspace key and delete key, also comprise add, subtract, the button of multiplication and division four kinds of operational symbols, its keyboard interface is connected with computing machine by USB connecting line, its numerical key 1-9 is divided into three rows, often arranges 3 numerical keys, puts in order and from left to right, be from top to bottom followed successively by, first row numerical key 9,8,7, second row numerical key 6,5,4, the 3rd row keyboard 3,2,1, numerical key 0 is the 3rd row; Enter key and backspace key the 4th row below numerical key.It adds, subtract, the button of multiplication and division four kinds of operational symbols is arranged on the upper right side of keyboard.Whole keyboard is sector structure from top to bottom, is applicable to left-handed operation.The utility model is simple and practical, quite a few numeral input, carriage return, backspace key is born by left hand, shares the workload of the right hand, play and slow down the unbalanced effect of Long-Time Service computer right-hand man.
Description
Technical field
The utility model relates to the special auxiliary keyboard of a kind of numeral input.
Background technology
Computing machine was universal in recent years, the utilization of various desk-top computer, notebook, panel computer allows people obtain great work efficiency, bring some worries also to the both hands of the mankind, particularly right hand mouse is more to be in particular in one hand, the time that all input right hands use is a lot, (be as the criterion with most people right-handed, left hand user does not then inquire into scope at this patent emphasis), even causes a large amount of right hands to obtain the occupational illness of " mouse hand "; Left hand is leisure on the other hand.So just cause the Long-Time Service of right-hand man unbalanced, the right hand is so busy that to obtain occupational illness, and left hand is not busy must can not help.And current keyboard arranges technology, for notebook computer, numerical key is arranged on again a row above keyboard mostly, and how inconvenient input is.Many patented technologies are for the design of keyboard, and concentrate on how with above numeric keypad inputting Chinese character, letter and digital to switch etc., the such as patent No. is the compound code element numeric keyboard shape code Chinese input of 201310262748.4; And for example application number: a kind of numeric keypad of 201410616538.5.These patents all cannot solve right-hand man's Long-Time Service this problem unbalanced, and this exists the necessity improved further.
Summary of the invention
The utility model object is to overcome above-mentioned the deficiencies in the prior art part, the special input small keyboard of a kind of external digital is proposed, be provided with and comprise numerical key 1-9, numerical key 0, enter key, backspace key, and delete key, also comprise and adding, subtract, take advantage of, except the button of four kinds of operational symbols, its keyboard interface is connected with computing machine by USB connecting line, its numerical key 1-9 is divided into three rows, often arrange 3 numerical keys, put in order from left to right, be followed successively by from top to bottom, first row numerical key 9, 8, 7, second row numerical key 6, 5, 4, 3rd row keyboard 3, 2, 1, numerical key 0 is the 3rd row, enter key and backspace key the 4th row below numerical key.It adds, subtract, the button of multiplication and division four kinds of operational symbols is arranged on the upper right side of keyboard.Whole keyboard is sector structure from top to bottom, is applicable to left-handed operation.In keyboard, numerical key 9 has upwards page turning to mark below, in keyboard, numerical key 3 has downward page turning to mark below, numerical key 7 gets back to page beginning mark below, numerical key 1 gets back to page closing tag below, numerical key 8 has arrow mark upwards below, and numerical key 2 has downward arrow mark below, and numerical key 6 has arrow mark to the right below, numerical key 4 has below arrow mark left, marks to add this numerical key by the shift key on computer keyboard and realize its function below value key.
This digital private input keyboard, by conventional numerical key and add, subtract, keyboard structure that the button of multiplication and division four kinds of operational symbols, enter key, backspace key and delete key make hand shape, be connected with computing machine with USB connecting line, quite a few numeral input, carriage return, backspace key can be born by left hand during such use, share the workload of the right hand, thus played and slow down the unbalanced effect of Long-Time Service computer right-hand man.
Certainly, the utility model proprietary numerical inputs special auxiliary keyboard and mainly considers the right-handed computer user of custom, so keyboard Designing is so that it is master that left hand uses, balances two hand workloads; But when reality uses, be also not limited to left hand and use, the right hand is also operable, is decided in its sole discretion by user.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing.
