Abstract
An electronic abacus is a novel calculation tool integrating the advantages and the characteristics of an electronic calculator and an abacus. The electronic abacus not only has the advantages of the calculator, such as multiple calculation functions, high calculation speed, no requirement for remembering a pithy formula, but also has the characteristics of the abacus, such as convenient and rapid digit input by dialing beads. The abacus part of the electronic abacus is a digit dialing device in an abacus structure in which six beads are arranged in one gear. The electronic calculation part adopts an integrated circuit for the calculator, and is only provided with functional keys and a digital screen. The two parts are connected into a whole by a circuit structure specially designed, so the electronic abacus combines the functions of digit input by dialing beads and electronic calculation.
Description
The present invention is the new computing tools that a kind of Abacus for calculation and electronic calculator are combined into, and is called " electrical abacus ".
Be extensive use of electronic calculator and two kinds of computational tools of Abacus for calculation at present both at home and abroad.But they all have its relative merits, and electronic calculator is the computational tool in modern age based on microelectric technique, and it has, and calculation function is many, and computing velocity is fast, need not to carry on the back advantages such as pithy formula, but exist button to send number inconvenient, and speed is slow, easy amiss shortcoming.Abacus for calculation is the ancient computational tool of China, and it has the pearl of dialling and send number convenient characteristics rapidly, but needs back of the body pithy formula, and computing velocity is slow, easily the shortcoming of miscalculating.So numerous financial and accountancy personnel generally are equipped with two kinds of computational tools, select for use by calculating content.The objective of the invention is the excellent characteristics of the two are combined, keep excellent characteristics separately, overcome its shortcoming, design a kind of novel electronic formula abacus, call " electrical abacus " in the following text.
Electrical abacus was once put on display in the inaugural meeting of Chinese rechoning by the abacus association in 79 years in China, but it only is that the two is pieced together, and can not overcome its shortcoming, does not produce so be eliminated.
Accompanying drawing is an electrical abacus synoptic diagram of the present invention, and (1) is the electronic calculator function keyboard among the figure, and (2) are digital display screen, and (3) are last pearl, and (4) are five on following pearl, and (5) are the pearl bar.
From scheming visible this electrical abacus, be the abacus of a kind of " one grade of six pearl " formula structure, Abacus for calculation is changed into one grade, the reservation rechoning by the abacus is dialled pearl and is sent number this elite, does not need berth shifting position, the left and right sides to give number, and further number speed is given in raising.Electronic calculator partly adopts the integrated circuit of certain model, (but also otherwise designed special IC) reservation function key.The two structure and interface circuit by particular design are combined into an organic whole.Interface circuit can be adopted various forms of noncontacting switches or soft-touch control, noncontacting switch and corresponding structure such as routine photo-electric, magneto-electric, induction type.
" one grade of six pearl " of the present invention formula is sent and is figured the dish structure, and it is to make pearl (3) and following pearl (4) be in upper and the next in original state that design has automatically reset device, resetting means.Other part that resets can be selected extension spring for use, is installed in pearl bar inside.The expression of numeral is: go up pearl representative (five), last pearl is upper, represents 1～5 respectively, ball under the last Zhu Chu during pearl under dialling separately
During the position, dial down pearl simultaneously and then distinguish 6～0.Send and stir pearl up and down when several, stir and loosen finger after putting in place, then six pearls automatically reset, wait for the two or three ... the pearl of dialling of long number is sent number, its multidigit shelves are looked the figure place of selecting counter for use, 8 or 12 of examples, send counting method as can be known from above-mentioned, abacus send several modes by many Dang Wei And capable calculate for number to change one grade of timesharing serial into send number, thereby solved the matching problem that abacus is dialled pearl and electronic calculator, realize dialling pearl and send number and be better than former abacus, computing function is utilized the advantage of microelectric technique, and the two is combined into real electronic type abacus.
The effect of interface circuit is that the position after bead is stirred is converted to corresponding on-off circuit, connects the corresponding pin of integrated circuit, substitutes the effect of button, finishes bead and is connected matching problem with electronic calculator.Above-mentioned several conversion interface circuit, all can realize this purpose through testing and verification, adopt which kind of circuit mode to set the corresponding bead structure of meter, consider following factors in addition: the 1. reliability of component devices, 2. component devices cost, 3. the processability of product structure of circuit, 4. the processability of product structure of bead, 5. aspect such as integrally-built volume is carried out the multianalysis comparison and is selected, along with the technical development meeting changes, but general purpose is to realize position-circuit conversion effect.Electrical abacus of the present invention is to adopt photo-electric noncontacting switch change-over circuit, bead post exercise position at present, change the condition that light activated element is subjected to light and lucifuge, thereby connect corresponding circuit, realize on-off action, replaced the effect of button.
The design of this electrical abacus is applicable to that the numerous financial and accountancy personnel in town and country carry out data statistics and use, and is not suitable for the cooperation scientific calculator.The whole nation has three or four thousand ten thousand people use abacus every day according to statistics, and 80 percent be to carry out plus and minus calculation, uses this abacus will improve their work efficiency, obtains their welcome.
At present both at home and abroad still at these two kinds of computational tools of development, the Japan U.S. starts rechoning by the abacus heat, abacus still has market, electronic calculator is with new, and good and cheap direction develops, the turnout of annual several ten million platforms, three or four hundred ten thousand of domestic annual production, illustrate two kinds of computational tools mutually with competing the development, its market is respectively arranged, along with economic development also with developed.Electrical abacus has the excellent characteristics of the two concurrently, has the novelty practicality, and certain market must be arranged, and is rising product.
Claims (3)
1, this " electrical abacus " is the computational tool that a kind of microelectronic circuits and abacus are combined as a whole, and send number to adopt and dials the pearl mode, and button is adopted in various computings, and numeral shows the data of its computation process.This send counting apparatus to be characterised in that: it is a kind of one grade of totally six bead structure that has only, abbreviates " one grade of six pearl " as and send counting apparatus (seeing accompanying drawing).
2, claim 1 described " one grade of six pearl " send counting apparatus to be characterised in that: pearl on it (3), following pearl (4), and all design has automatic reset mechanism, and its adopts extension spring also to design within pearl bar (6).
