Abstract
The utility model relates to an input and display disc for abacus type electric calculators, which has the similar appearance and operation method as a traditional abacus. The utility model can be singly used for carrying out plus minus operations quickly and can also carry out such comparatively complicated operations fast as multiply divide when connected with a common calculator through an interface circuit. The utility model combines the respective advantages of a traditional abacus and a common calculator.
Description
The utility model relates to a kind of input and display panel of abacus type electrical counter.
The existing electrical counter that relies on the keyboard input digit, its digital input key and digital indicator can only be realized numeral input and the function that shows respectively, and both all do not have calculation function.Traditional abacus is then different therewith, and the bead collection input of abacus, computing and three kinds of functions of demonstration are one.Thereby when simple operation such as adding and subtracting, its speed is faster than electrical counter, but when carrying out complex calculation such as multidigit multiplication and division, then is that the speed of electrical counter is fast.For this reason, people are sometimes in order to improve arithmetic speed, still use abacus when simple operation such as adding and subtracting, and then use electrical counter when carrying out complex calculation such as multidigit multiplication and division.But in the time of will so carrying out various hybrid operation, will constantly forward numeral on the abacus to from electrical counter, and forward on the electrical counter from abacus, this just makes total arithmetic speed be very limited.
The purpose of this utility model is to provide a kind of advantage that can integrate abacus and electrical counter, can improve the input and the display panel of the abacus type electrical counter of electrical counter arithmetic speed.
To achieve these goals, it is similar that the utility model has designed a kind of outward appearance to traditional abacus, method of operating is also similar and can replace the input and the display panel of the abacus type electrical counter of the digital input key of common electrical counter and display simultaneously, its primary structure is, it has an Abacus frame (101), there is a crossbeam (102) side on the upper side in framework, with the crossbeam quadrature many intervals position axle (103) uniformly vertically arranged, on every position axle, be provided with and be no less than five bead (A, B, C, D, E), wherein have at least a bead to be located at crossbeam top (A), have at least four beads to be located at crossbeam below (B, C, D, E), each bead is formed by luminophor (201) and power switch (202) thereof, the connected mode of luminophor and its power switch is that energized was luminous when the bead of crossbeam top was set aside, on powered-down when dialling, make when dialling on the bead of crossbeam below energized luminous, powered-down when setting aside, every position axle also be provided with the level height represent respectively each bead on/off state a plurality of output terminals (
), on the crossbeam between adjacent two position axles and the left side of crossbeam and right-hand member establish respectively one represent the input of radix point and display key (
), the input of radix point and display key are made up of luminophor (301) and power button (302) thereof, all radix point inputs all are connected (can only have a radix point to show at synchronization) by the mode of single channel gating with display key, and each radix point input is equipped with an output terminal of just representing its on/off state with level with display key
（
）。
Such input and display panel, because of having and traditional abacus similar in appearance and method of operating, just with the luminous displacement that replaces traditional bead of its bead, the people who gets used to calculating on an abacus can carry out skillfully by means of it separately and plus and minus calculation fast fully.In the time will carrying out complex calculation such as multiplication and division, can its result be returned abacus show by luminous digital and the scale input common electrical counter of interface circuit again bead.So just have both simple operations such as to carry out plus-minus method fast, can carry out the complicated good effects of calculating such as multiplication and division again fast.
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described.
Figure one is the schematic appearance of an embodiment of the utility model.

It is the input end (parallel input) of electrical counter.Can find out from figure, any one in pushing a ', b ', c ',
The capital changes accordingly, and it is 1 that a level is promptly arranged accordingly.When not pushing a ', b ', c ', two kinds of situations are arranged: it is 1 o'clock that a level is arranged among a kind of Za of being, Zb, the Zc,
The state of end changes with the variation of Za, Zb, Zc; Second kind is that the level of Za, Zb, Zc is at 0 o'clock,
Output all with
Variation and become.The relation object of input, demonstration and the ock of the relation of the input of radix point, demonstration and ock and numeral seemingly.Explanation is what time at last: the first, and this is novel for the people that can not calculate on an abacus, and its arithmetic speed is also come soon than general electrical counter during use.Because general electrical counter needs " looking for " numeral when input, this novel input then is to import (comprising radix point) successively.And this novel being easy to is corrected mistakes.The second, for also available novel demonstrations such as the clock and watch of general electrical counter, calendars.
