Description

Electronic postcode quick-locating abacus

The utility model relates to a kind of quick Position abacus that has the electronic digital display structure.

Abacus is the traditional popular style counting operational tool of China, so far not still in vogue not waning, has the superiority of not replacing, but its weak point is arranged also, only show as a kind of single bead form, lack the form of expression of contrast computing, amass, decide through consultation the bit comparison difficulty, easily cause location computing mistake, influence arithmetic speed efficient.The reason of searching to the bottom mainly is to lack a kind of aid that cooperates contrast computing location.

And design by Ye Yaomo, the patent No. is 92236398.6 " a kind of novel abacus of digital rechoning by the abacus mating type ", its feature is the entablature position at abacus, if one or six face length square box, establish row's digital wheel in the box, but,, problems such as above-mentioned computing location difficulty have been solved preferably by simple and clear locating rule with the locator card of a move left and right.But still having its weak point, mainly is that to take off the digital wheel process still slower, and arithmetic speed is used in influence.

Task of the present utility model provides the novel counting operational tool that a kind of electronic digital combines with rechoning by the abacus, to solve the above-mentioned problem that exists.

Task of the present utility model is finished as follows: it is to utilize existing general abacus, inserts the box body of a charged sub-button digital display device, is provided with locating device in abacus central sill position.Concrete design is as follows: remove the entablature of former abacus, make into one isometric with entablature, constitute a single piece with abacus, but six face length square box of folding.The electronic key digital display device is equipped with in left side in the box, is presented on the liquid crystal display with the number button, and a liquidation device button is established in the centre of box body, and writing case is established in the room, right side.But on the central sill of abacus, establish the location slide calliper rule of a move left and right in addition.In the sill position of abacus, make one into and be provided with the computing indicating device, but it form by one oval computing indicating card that is inserted in move left and right, with the indication count the not gear of multiplication and division number of Buddhist monk in multiplication and division.

According to above-mentioned design, carry out the computing location by given straightforward method during computing, just can reach a step location and put in place, fast the purpose of computing location.

Use and the computing localization method

1, the computing of plus-minus method location.Position mark on the slide calliper rule of location is moved to suitable gear, and figure place or the section mark of showing by location slide calliper rule subscript carried out the rechoning by the abacus signed magnitude arithmetic(al) respectively then, and operation result is read and counted or difference according to the figure place on the slide calliper rule of location.

2, the long-pending or merchant's of multiplication and division localization method.The position mark that to locate earlier on the slide calliper rule moves to the appropriate location, on multiplicand or dividend row bead." opening " key and figure key that next is pressed on the electronic digital device are presented on the liquid crystal display multiplier or divisor, and then by following locating rule, the running fix slide calliper rule carry out the computing location:

1. the long-pending location of multiplier: move slide calliper rule location, location according to the multiplier figure place on the liquid crystal display, multiplier has several integer figures, a position mark of location slide calliper rule just adds to the right down from individual position and moves several gears and (do not contain a position grade, down together), as 18 * 897, multiplier is three integer-bit, individual position mark three gears that just move right under individual, position mark gear after the displacement is exactly a position long-pending after the computing.

Multiplier is that decimal (refers to not have before the radix point decimal of integer, behind the radix point several " 0 " are arranged down together), individual position is marked just to add left down from individual position and is moved several gears, as 138 * 0.0005, three " 0 " are arranged behind the radix point, individual position is marked just to add left down from individual position and is moved three gears, and gear is marked in the position after the displacement, is exactly a position long-pending after the computing.

Multiplier is a decimal, and the first place does not have " 0 " behind the radix point, and individual position mark remains on original position and is not shifted, and this gear is exactly a position long-pending after the computing.

2. divisor merchant's location.The orientation long-pending with multiplier is opposite, that is: divisor has several integer-bit, and individual position is marked just to add left down from individual position and moved several gears, and gear is marked in the position after the displacement, is exactly a position of discussing after the computing.Divisor is a decimal, radix point has several " 0 " position, individual position mark just adds to the right down from individual position and moves several gears, the position mark gear after the displacement, be exactly discuss after the computing.Divisor is a decimal, does not have " 0 " behind the radix point, and individual position mark just remains on original position and is not shifted, and this gear is exactly a position of discussing after the computing.

Computing is pressed " pass " key after finishing, and promptly powered-down is eliminated the number on the liquid crystal display.

In addition, in division arithmetic, get merchant's back multiplication and division operational method earlier at the first last shelves of dividend or preceding second gear, can rise, individual position mark is added left again move the position that one or two gear is discussed surely at above-mentioned gear after moving a mark for taking.

The usage of computing indicating card.In the calculating process of multiplication and division, can smoothly indicating card be moved on to just in the gear lower end of computing, to show that this number is just in computing, next figure place is not computing as yet, during next figure place of computing, move on to the lower end of next figure place more smoothly, can avoid leak the mistake of shelves or repetitive operation.

The quick Position abacus of this electronic digital:

1, simplified localization method effectively, can be by given simple and clear locating rule, a step location puts in place, shortens location time-histories and meter position process, removes complicated meter position program from, improves arithmetic speed and efficient.

2, the contrast ordered series of numbers of multiplication and division is on liquid crystal display, and it is fast and convenient to peek, and writing is clear eye-catching, convenient contrast computing.

3, the electronic digital device is taked simple miniwatt circuit, and scientific and reasonable for structure, production technology is simple and easy, and cost is low, is suitable for producing in batches implementing, and practical function is remarkable, and the writing case of setting up has increased the utilization ratio and the added value of apparatus.
