The utility model discloses collect the function in an organic whole of electronic calculator and abacus, have decimal point memory function, put into the function that has priority discernment again, can be not only quick but also accurate carry out digital operation.
Description
The utility model belongs to counter, refers in particular to the numeration rule design by the traditional abacus of China, the electrical abacus that key is dialled in arrangement.
Mental arithmetic, written calculation, rechoning by the abacus are used in daily computing always, and used tool is paper, pen, abacus or counter, large-scale computing applying electronic computing machine.Abacus to add, subtraction, especially speed adds, and is the rapidest, inferior a little to multiplication and division, then counter is the rapidest to other arithmetic.All will once move with compute mode to each numeral but use counter to exist, fast sign of operation or equal sign, also be so No. zero, so still comparatively bother on program.
The purpose of this utility model is: it is more simple to design a kind of computing formality, have again counter and abacus function, arrange the electrical abacus of dialling key according to the numeration rule of abacus.
The utility model is made up of casing, button, display unit, it is characterized in that: dial the numeration rule setting of key according to abacus, numeral 5 is inserted group key and is arranged on top, casing front, the below is provided with less than 5 numeral and inserts group key, the centre is provided with radix point and inserts group key, the positive right-hand calculation function key that is provided with of casing, the contact of dialling key and movement is positioned at the side of key bottom.
The function of sub-counter of the utility model current collection and abacus has the radix point memory function in one, inserts the function with preferential identification again, can not only carry out digital operation fast but also accurately.Especially the contact of key is positioned at the side of key bottom, and it more adapts to the acting characteristic of finger, drives finger tip with finger-joint, force in the key position from the side, be similar to group pearl action that bamboo is calculated, dial this notion of key so introduce, can avoid finger tired, reduce error rate.
