The bead button of below, described note site is pressed, and when the light emitting diode that this bead button is corresponding changes open mode into by closed condition, be positioned at the top of this bead button column and remembering that light emitting diode corresponding to bead button below site becomes open mode.
The bead button of described note site below is pressed, and light emitting diode corresponding to this bead button be while changing closed condition into by open mode, and light emitting diode corresponding to bead button that is positioned at the below of this bead button column becomes closed condition.Beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, has following advantage and good effect:
The utility model represents bead with bead button, clicks certain bead button, can change the state of bead, then clicks this bead button, can recover original state.In addition, this electrical abacus, when pressing certain bead key and make bead state variation, also has the function that drives some other bead state variation.
The utility model will be dialled pearl and change over by pearl, operation is simpler than dialling pearl, computing velocity is faster than dialling pearl, by pearl computing, there is not floating pearl and band pearl, therefore improved the accuracy of computing, also easily grasped the computing by pearl " touch system ", by the simulation of abacus mental calculation dial pearl or thinking dial simulation that pearl is modified into abacus mental calculation by pearl or thinking by pearl, finally form the bead presentation overlapping operation technology of abacus mental calculation, this operative technique comes from rechoning by the abacus but higher than rechoning by the abacus.Adopt this abacus mental calculation, in computing, only present jewel presentation, need not remember frame, beam, the shelves of dark pearl presentation and abacus, therefore can play simplification presentation, reduce the effect of memory.
With the utility model, when by pearl computing, accomplished that bead does not move.It can not only count and computing as calculating on an abacus, and in abacus mental calculation study, clicks bead key and can also proofread the bead Global rehearsal that this single stepping presents instantly.After skilled, reality be can break away from by pearl operation, the synchronous operation of bead presentation and the overlapping operation of bead presentation further trained.So, to grasp after these bead presentation operations, the speed of abacus mental calculation and accuracy rate will be significantly improved.
