Describe in detail below in conjunction with accompanying drawing:

As shown in the figure, the utlity model has a main cartridge, main cartridge is the flat box of rectangle, and the left side is between chart board is hidden 1, and right-hand part is between figure demonstrating 2; Cooperate with slideway 20,21 in the main cartridge and to be separately installed with master map plate 17, secondary chart board 18, said master map plate 17 is that mint-mark has numeral 15 on the plate face, with digital corresponding mint-mark figure 16 is arranged in digital bottom, and the master map plate that affects pin 7 is installed in the side, said secondary chart board 18 be mint-mark on the plate face have with the master map plate on the figure 19 of relative position, and the side is equipped with the secondary chart board that affects pin 8, and secondary chart board is a hyalomitome.

Shrouding and master map plate shift out first digital position left and have digital display window 3 before between the demonstration of main cartridge, stay to have laterally successively that figure demonstrating window 4, secondary chart board affect pin to move hole 5, the master map plate affects pin to move hole 6.Preceding shrouding Lower Half in the main cartridge left side has slideway 14, is equipped with demonstration operation panel controller chassis 13 in slideway 14, is equipped with operation panel 12 in the operation panel controller chassis 13.Operation panel 12 can upper and lowerly slide in controller chassis 13.Operation panel 12 lower left corners have the master map plate and affect pin control mouthfuls 9, and it is contour that operation panel upper edge and secondary chart board affect pin to move the lower edge, hole, and edge, operation panel upper edge according to the major-minor chart board on centre of figure comply with apart from length and have equidistant recess 10.Be provided with control knob 11 at operation panel 12 middle parts, when pushing away on control knob 11 operation panels, operation panel can be controlled the control pin of major and minor chart board simultaneously, and makes its left and right same moved further.

Numeral on the master map plate is 1～20 oppositely discharge successively.Said structure is like this demonstration to 20 with interior plus-minus like this:

1, in the time of between major and minor chart board coexists and hides, digital display window is " 0 " state.

2, addition demonstration: on " 0 " state basis, promote the demonstration operation panel to the right, can be by the summand requirement, summand word on the master map plate and quilt are added figure; The push-up operation plate moves to right major and minor chart board synchronously again, up to the addend figure that shifts out on the secondary chart board.At this moment figure demonstrating hole window promptly demonstrates the linking of addend and two kinds of color figures of summand, digital display window demonstrate " with " number.

3, subtraction demonstration: beginning is the same with the addition demonstration, and right the deduction shown operation panel, the master map plate is moved to right show minuend figure and numeral, and is slack, promotes secondary chart board more separately to the right and affects pin, makes secondary chart board shift out the subtrahend figure by the subtrahend requirement.At this moment the original minuend figure that shows in figure demonstrating hole is just told and is mended the cover part and do not cover part.Being capped part is exactly the part that deducts, and not covering part is exactly " poor ", will push away on the operation panel again, major and minor chart board is moved to left synchronously, up to be capped part all move into hide between, digital display window promptly demonstrates difference, the figure demonstrating hole demonstrates the figure number of " poor ".
