Overview
(57) [Overview]
PROBLEM TO BE SOLVED: To provide an abacus which is simple in structure, easy in manufacture, capable of mastering the mental calculation of more figures, and convenient in portability and carriage by reducing the size thereof by solving problems with a conventional abacus that five beads are pierced for each figure bar (the figure bars are partitioned by a middle frame with one bead on the upper side and four beads pierced on the lower side), the structure has been complicated, the manufacture has been troublesome, mental calculation which is possible if the operation is mastered has been difficult to master because the quantity of images occurring in mind for each figure is large, and thus, calculation with many figures has been difficult.
SOLUTION: In the abacus, figure bars 2 with three beads 1 pierced therethrough are fitted to a frame 3.
Scope of Claims
[Patent Claims]
[Claim 1] Abacus in which three beads are passed through each girder rod having a length of five or more beads
Detailed Description
[Detailed description of the invention]
[0001]
[Technical Field]The length of each beam bar of the abacus is set to five or more beads, and three beads are passed through each beam bar.
[0002]
[Prior art] In a conventional abacus, five beads are passed through each beam bar (upper and lower parts are divided by a middle bar, and one bead is passed through the upper part and four beads are passed through the lower part). For this reason, the structure is complicated and the manufacturing is time-consuming. In addition, with respect to the mental calculation which can be performed if the user is skilled in the calculation, since the amount of images floating in the brain used for one digit is large, it is difficult to perform the calculation with a large number of digits.
[0003]
[Features of Invention]However, according to the present invention, the structure is simplified to facilitate the manufacture, and when the operator is skilled in the operation, the operator can calculate a larger number of digits in the mental calculation. The size of an abacus becomes small.
Therefore, it is convenient to carry and transport.
[0004]
Principles of the InventionIf the present invention constitutes five space from two space and three objects, it will apply the principle that the pattern will be ten kinds, *****, *****, *****, *****, *****, *****, *****, *****, *****, and *****.
[0005]
[Effect of the Invention] Since the present invention has such a simplified structure, it is easy to manufacture and it is possible to calculate a larger number of digits in the mental calculation. Further, since the size of the abacus is reduced, it is convenient to carry and transport.
