Abstract
The utility model discloses a keyboard available for Chinese characters non-code fast input method, which is composed of an operation keyboard, a printed circuit board and a keyboard interface line, wherein, HD (7) 279A functional chip which can treat rank data information is adopted; keys on the operation keyboard are arranged according to five rows and six lines arrangement. The utility model is used as an auxiliary keyboard of a main keyboard of a computer, and has the advantages of convenient and intuitionistic operation and high input speed.
Description
The utility model relates to microcomputer hardware, and particularly a kind of Chinese character that is applicable to does not have the keyboard of yard quick input method.
Input method of Chinese character is a lot of at present, generally comprise language input method, hand-writing input method, coded input method, differ from one another, the language error rate for input is higher, handwriting input needs the hardware device support, the cost height, and speed is slow, and the coding input then all has complicated code taking rule or radical classifying rules, need memory, the learning and mastering difficulty, (application number: 00112688.1) provide a kind of " Chinese-character intelligent writing input method and writing input board ", this method need not to adopt coding to Patent Office of the People's Republic of China's application technology, concerning the operator, do not need the requirement of special training and culture procedure, and speed is fast, error rate is low.Because existing operation keyboard is the PC keyboard of 101-103 key, when applying to this Chinese character and do not have the quick input method of sign indicating number, poor for applicability, the cloth key is unreasonable, easy other function operations that influences of while.
Goal of the invention of the present utility model provides a kind of Chinese character that is applicable to does not have the keyboard of yard quick input method, this keyboard and the corresponding connection of active computer operation keyboard interface, as the auxiliary keyboard of active computer operation keyboard, has the operation intuitive and convenient, fireballing characteristics.
Goal of the invention of the present utility model is achieved in that
The utility model comprises operation keyboard, printed-wiring board (PWB), keyboard interface line, it is characterized in that:
The button of A, operation keyboard is arranged by 5 row, 6 row, and Chinese stroke sign is arranged on each button Face;
B, printed-wiring board (PWB) comprise capable circuit board and column circuits plate, and the superimposed operation keyboard that is positioned at, below button;
C, the HD7279A functional chip that can handle the row and column signal is arranged on the printed-wiring board (PWB), 14 pins of HD7279A functional chip, 13 pins, 12 pins, 11 pins, 10 pins are connected with button point on row circuit board from 1 to 5 every row successively respectively, 18 pins, 19 pins, 20 pins, 21 pins, 22 pins, 23 pins are connected with behaviour's column circuits plate from 1 to 6 button point that whenever lists successively respectively, and two signal pins of keyboard interface line are connected with 8 pins with 7 pins of HD7279A functional chip respectively, series capacitance ground connection after 1 pin of HD7279A functional chip and the 2 pin parallel connections, ground connection after 4 pins and the 6 pin parallel connections, ground connection after 27 pins and the capacitances in series, and with 28 pins, the parallel circuit of 1 pin and 2 pins is connected with the power pin of keyboard interface line simultaneously, and the input power supply is 5 volts of direct supplys.
The utility model HD7279A functional chip is the product that adopts HIT, and its effect is: data are carried out acquisition process.
The utility model and the corresponding connection of active computer operation keyboard interface as the auxiliary keyboard of active computer operation keyboard, have the operation intuitive and convenient, fireballing characteristics.
Provide accompanying drawing of the present utility model below:
