2. Description of the Related Art As is well known, abacus is the oldest and simplest calculator in Japan, and it is the cheapest, quickest and most accurate calculator that makes the best use of Japanese dexterity. , Already recognized worldwide. The use of abacus is useful not only for improving the calculation ability but also for stimulating nerves concentrated in the fingertips, which is also beneficial for health such as promoting blood flow in the brain. It has many advantages. By the way, in order to improve the skill of abacus calculation, the practice is repeated first, and as the skill improves, training such as mental arithmetic will be performed, so that it becomes possible to calculate addition, subtraction, multiplication and division with more digits. It is a thing. And it goes without saying that everyone hopes that their skills will improve faster with shorter training. From this viewpoint, the present inventor has been conducting research for many years on more efficient improvement of abacus skill and promotion of health by stimulating acupuncture points on fingers and fingers. At present, most of the useful instruments have not been researched and developed. In other words, the structure of the abacus has not been specially improved since ancient times, and the structure is such that the abacus beads are movably supported in a rectangular frame, and therefore practice is repeated over a relatively long period of time. , The skill is gradually improving.

[0003]

As described above, in the conventional abacus, there is a problem that it cannot be said that a mechanical device for more rational practice is provided in the process of improving the skill. The present invention has been made in view of such drawbacks, and an object of the present invention is to provide an abacus with a finger trainer that more efficiently improves abacus skill.
