Description

本発明は、操作ミスを防止することが可能な算盤に関するものである。   The present invention relates to an abacus capable of preventing operation mistakes.

近年、計算能力の向上といった算盤のもつ効用が見直されつつあり、多くの人が再び算盤を学習している。この算盤の操作において、もっとも犯しがちなミスは、操作しようと意図していた珠に隣接する左右の珠をも合わせて誤操作してしまうことである。   In recent years, the utility of abacus, such as the improvement of computing ability, is being reviewed, and many people are learning abacus again. In the operation of this abacus, the most common mistake is to misoperate the left and right pearls adjacent to the pearl that was intended to be operated.

この誤操作を軽減すべく様々な研究がなされており、例えば運珠の際、指の傾斜方向の隣の算盤珠に干渉する傾向があり、その方向の算盤の座高を低くすれば操作性が向上するとの観点から、座高が上(かみ)から下(しも)に至って、傾斜した算盤などが知られている(例えば、特許文献1を参照。)。また、算盤珠の回転を抑制することで、結果として誤操作を低減させる機構も知られている(例えば特許文献2を参照)。   Various studies have been made to reduce this misoperation.For example, when carrying a bead, there is a tendency to interfere with the adjacent abacus bead in the direction of the finger's inclination, and the operability can be improved by lowering the sitting height of the abacus in that direction. From this point of view, an inclined abacus is known in which the seat height reaches from the top (bite) to the bottom (step) (see, for example, Patent Document 1). Moreover, the mechanism which reduces a misoperation as a result by suppressing rotation of an abacus bead is also known (for example, refer patent document 2).

株式会社雲州堂ホームページ http://www.unshudo.co.jp/story/collection/2009/02/008.html(平成26年6月28日確認)Unshudo website http://www.unshudo.co.jp/story/collection/2009/02/008.html (confirmed on June 28, 2014)

しかしながら、いかに傾斜をつけた算盤を用いようとも、また算盤珠の回転が抑制された算盤を用いようとも、操作者の算盤操作技術の習熟度合いによっては、操作しようとする算盤珠に隣接する算盤珠をも誤操作してしまうことは避けられなかった。誤動作に気がついた場合は、その時点で修正操作を行うことが可能であるものの、演算時間が増大してしまうことは避けられない。誤動作に気がつかない場合は演算結果に誤りが含まれてしまう為、さらに多大な不利益が発生する。   However, regardless of how inclined the abacus is or whether it uses a abacus with reduced abacus rotation, the abacus adjacent to the abacus to be operated depends on the operator's level of skill in abacus operation. It was unavoidable to misoperate the beads. If a malfunction is noticed, a correction operation can be performed at that time, but an increase in calculation time is unavoidable. If a malfunction is not noticed, an error is included in the calculation result, which causes a further great disadvantage.

そこで本発明は、同時に二つの算盤珠を操作してしまうことによる誤算や演算時間が長引くという問題を根本的に解決する算盤を提供することを目的とする。   Therefore, an object of the present invention is to provide an abacus that fundamentally solves the problem of miscalculation and prolonged computation time caused by operating two abacus beads simultaneously.

本発明の誤操作防止算盤は、算盤珠の一部を加工することで隣の算盤珠への干渉を抑制し、かつ算盤珠の回転を防止する機構を有することを特徴とする。   The misoperation-preventing abacus of the present invention is characterized by having a mechanism that suppresses interference with an adjacent abacus bead by processing a part of the abacus bead and prevents rotation of the abacus bead.

本発明の誤操作防止算盤は、算盤珠と隣の算盤珠の間にストッパーを有することを特徴とする。   The misoperation preventing abacus of the present invention is characterized by having a stopper between the abacus bead and the adjacent abacus bead.

本発明によれば、算盤珠の回転を防止する機構によって算盤珠を加工した部分が算盤の操作面に並ぶことにより指との接触領域を限定せしめ、その結果として指が隣の算盤珠に干渉することを防ぐ効果を常に発揮する算盤を提供することができる。   According to the present invention, the area where the abacus bead is processed by the mechanism that prevents the rotation of the abacus bead is arranged on the operation surface of the abacus to limit the contact area with the finger, and as a result, the finger interferes with the adjacent abacus bead. It is possible to provide an abacus that always exhibits the effect of preventing it.

本発明によれば、算盤珠と隣の算盤珠の間にストッパーを有することによって、操作すべき算盤珠と隣接する算盤珠の区別を操作者が容易に指で認識可能な算盤を提供することができる。   According to the present invention, by providing a stopper between an abacus bead and an adjacent abacus bead, it is possible to provide an abacus that allows an operator to easily recognize the difference between an abacus bead to be operated and an adjacent abacus bead with a finger. Can do.

以下、本発明をさらに詳しく説明する。
従来の算盤は、図1に示すがごとく、算盤珠と算盤珠が近い位置にて整列している為に、指を操作すべき算盤珠に接触させようとしても、誤って左右に隣接する算盤珠に接触してしまうことがあった。この場合、意図しない算盤珠の操作、すなわち誤操作が発生してしまう。
Hereinafter, the present invention will be described in more detail.
A conventional abacus, as shown in FIG. 1, because the abacus bead and the abacus bead are aligned close to each other, even if you try to bring your finger into contact with the abacus to be operated, There was a case where it touched the pearl. In this case, an unintended operation of the abacus bead, that is, an erroneous operation occurs.

誤操作を防ぐには、算盤珠に指をあてた場合、指が算盤珠に安定するよう算盤珠の形状を工夫すればよい。さらに、当該形状が常に算盤の上面(指で操作する面)を向くように工夫することで、常に安定して特定の算盤珠を指で操作することが可能になる。   In order to prevent an erroneous operation, when a finger is placed on the abacus bead, the shape of the abacus bead should be devised so that the finger is stabilized on the abacus bead. Furthermore, by devising that the shape always faces the upper surface of the abacus (surface operated by the finger), it becomes possible to always operate a specific abacus bead with the finger stably.

もうひとつのアプローチは、指がある算盤珠とその両隣の算盤珠を容易に認識可能となるよう、算盤の形状を工夫することである。   Another approach is to devise the shape of the abacus so that the abacus with a finger and the adjacent abacus can be easily recognized.

次に参考例及び実施例により本発明をさらに詳細に説明するが、本発明は以下に示す実施例に限定されるものではない。   EXAMPLES Next, although a reference example and an Example demonstrate this invention further in detail, this invention is not limited to the Example shown below.

参考例
算盤珠2の操作面にあたる部分を図2の除去部分4に示すように除去する。すなわち、算盤珠を軸3方向から見て、時計の1時から2時、そして10時から11時に相当する部分を除去する。この構成を採用することで、算盤珠2の指1に接する領域が通常の算盤珠2よりも限定される。ただ、通常の算盤珠2は、軸3で連結されているが、軸を中心に回転自由となっており、そのままでは除去部分4を算盤の一定の領域に安定させることはできない。
Reference Example A portion corresponding to the operation surface of the abacus 2 is removed as shown in a removal portion 4 of FIG. That is, when the abacus bead is viewed from the direction of the axis 3, the portion corresponding to 1 to 2 o'clock and 10 to 11 o'clock is removed. By adopting this configuration, the area in contact with the finger 1 of the abacus 2 is more limited than that of the normal abacus 2. However, although the normal abacus 2 is connected by the axis | shaft 3, it is free to rotate centering on the axis | shaft, The removal part 4 cannot be stabilized in the fixed area | region of an abacus as it is.

そこで、図3に示すとおり、通常の軸3に加えて、回転防止用芯6を珠を貫通するように軸3に平行に配置することにより、除去した算盤珠5が回転することを防止する。さらに回転防止用芯6を囲むように、除去した算盤珠5の肉付けを行うことで、回転防止用芯6や軸3を通した算盤珠を繰り返し利用しても十分な耐久度を備えることができる。肉付けは、軸3を超えたあたりまで行えば十分その効果を発揮することが可能である。この肉付けは底面から見て四角形となるよう、すなわち算盤珠を四角柱状となるよう構成するとなおよい。加工が容易である為である。   Therefore, as shown in FIG. 3, in addition to the normal shaft 3, the rotation prevention core 6 is disposed in parallel to the shaft 3 so as to penetrate the bead, thereby preventing the removed abacus 5 from rotating. . Further, by removing the abacus bead 5 so as to surround the anti-rotation core 6, sufficient durability can be provided even if the abacus bead passed through the anti-rotation core 6 and the shaft 3 is repeatedly used. it can. The effect can be sufficiently exerted if the meat is made to the extent that the shaft 3 is exceeded. This fleshing is more preferably configured to be a quadrangle when viewed from the bottom, that is, the abacus bead is a quadrangular prism. This is because processing is easy.

その結果、図4に示すとおり、操作を意図した除去した算盤珠5に隣接する除去した算盤珠5と指の間にスペース7が存在することにより、指が意図しない除去した算盤珠5に接触してしまう可能性を著しく減少させることができる。さらに、回転防止用芯6の存在によって除去した算盤珠5が回転することがないので、常に操作面に凸型の形状が並ぶことにより、上記効果を恒久的に発揮することが可能である。   As a result, as shown in FIG. 4, the space 7 between the removed abacus 5 adjacent to the removed abacus 5 intended for operation and the finger makes contact with the removed abacus 5 that the finger does not intend. This can significantly reduce the possibility of the occurrence. Furthermore, since the removed abacus 5 is not rotated due to the presence of the anti-rotation core 6, the above effects can be exhibited permanently by always arranging convex shapes on the operation surface.

実施例1
参考例と同様に、回転防止用芯6を囲むように除去した算盤珠5の肉付けを行う。こうすることで、回転防止用芯6や軸3を通した除去した算盤珠5を繰り返し利用しても十分な耐久度を備えることができる。肉付けは、軸3を超えたあたりまで行えば十分その効果を発揮することが可能である。この肉付けは底面から見て四角形となる整形する。そして肉付けを行わない箇所は除去することにより、算盤珠を四角柱状となるよう整形する。なお、大量生産を行う際は最初から四角柱を用いて生産することとしてもよい。
Example 1
As with the reference example, the abacus 5 removed so as to surround the anti-rotation core 6 is fleshed out. By carrying out like this, sufficient durability can be provided even if it uses repeatedly the abacus bead 5 which removed the rotation prevention core 6 and the axis | shaft 3 through. The effect can be sufficiently exerted if the meat is made to the extent that the shaft 3 is exceeded. This fleshing is shaped as a square when viewed from the bottom. Then, by removing the parts that are not fleshed out, the abacus bead is shaped into a quadrangular prism shape. In addition, when performing mass production, it is good also as producing from a square pillar from the beginning.

そして算盤珠の上部に、図5に示すとおり算盤の上から見て上下左右に突起を肉付けする。このうち、左右に設置した突起を誤操作防止用突起9と呼称し、上下に設置した突起を算盤珠操作改善用突起8と呼称することとする。その結果、算盤を上から見て、操作者に近い側から、算盤珠操作改善用突起8、算盤珠の上部、算盤珠操作改善用突起8という構成となる。左右方向では、誤操作防止用突起9、算盤珠の上部、誤操作防止用突起9という構成となる。   And as shown in FIG. 5, protrusions on the top, bottom, left, and right of the top of the abacus are thickened. Among these, the protrusions installed on the left and right are referred to as erroneous operation preventing protrusions 9, and the protrusions installed on the top and bottom are referred to as abacus operation improving protrusions 8. As a result, the abacus operation improvement protrusion 8, the abacus operation improvement protrusion 8, and the abacus operation improvement protrusion 8 are configured from the side closer to the operator when viewed from the top. In the left-right direction, the structure includes a misoperation preventing projection 9, an upper part of the abacus bead, and an misoperation preventing projection 9.

その結果、図6に示すとおり、操作者からみて近い側や遠い側の算盤珠操作改善用突起8に指をひっかけることで、操作を意図した突起付き算盤珠10をしっかりと操作することが可能となり、突起付き算盤珠10を容易に上下に弾くことが可能となる。また、誤操作防止用突起9の存在により、指と操作を意図した突起付き算盤珠10の接触状態を安定させることが可能となり、隣の桁に属する突起付き算盤珠10を誤って操作する虞がなくなる。さらに、回転防止用芯6の存在により突起付き算盤珠10が回転することがないので、常に操作面に算盤珠操作改善用突起8や誤操作防止用突起9が並ぶことにより、上記効果を恒久的に発揮することが可能である。   As a result, as shown in FIG. 6, it is possible to firmly operate the abacus 10 with protrusions intended for operation by hooking a finger on the protrusion 8 for improving abacus operation on the side closer to or far from the operator. Thus, the abacus 10 with protrusions can be easily flipped up and down. Further, the presence of the misoperation preventing projection 9 makes it possible to stabilize the contact state between the finger and the abacus 10 with projections intended for operation, and there is a risk that the abacus 10 with projections belonging to the adjacent digit will be erroneously operated. Disappear. Further, since the abacus 10 with protrusions does not rotate due to the presence of the anti-rotation core 6, the above effects are made permanent by always arranging the abacus operation improving protrusions 8 and the erroneous operation preventing protrusions 9 on the operation surface. It is possible to demonstrate it.

実施例1の八角柱を用いる変形例
算盤珠への肉付けを八角柱となるよう図7のAに記載のごとく構成する。そして、八角柱の八角形となる底面を下となるよう、すなわち側面を軸3で貫くことにより算盤を構成する。この構成を採用することで、算盤の状態を初期化する動作である「ご破算」を行う際に、指を滑らかに算盤珠間を移動させることが可能となる。なお、大量生産をおこなう場合は、双円錐台状の算盤珠に肉付けを行うのではなく、最初から八角柱を用いて生産することとしてもよい。
Modification Example Using Octagonal Pole of Example 1 As shown in A of FIG. And an abacus is comprised by penetrating the side face with the axis | shaft 3 so that the bottom face used as the octagon of an octagonal column may become down. By adopting this configuration, it is possible to smoothly move the finger between the abacus beads when performing the “breakdown” operation that initializes the abacus state. In addition, when mass production is performed, it is good also as producing from an octagonal column from the beginning instead of fleshing a binocular truncated conical abacus bead.

実施例1の楕円を用いる変形例
図7のBに示すとおり、上記肉付けを底面から見て楕円(隣の桁に向かって長辺、同じ桁の珠に向かって短辺となる楕円。)、すなわち算盤珠を楕円柱となるよう構成しても同様に容易にご破算を行うことが可能である。なお、大量生産を行う場合は、最初から楕円柱を用いて生産することとしてもよい。
Modification Example Using Ellipse of Example 1 As shown in FIG. 7B, an ellipse (an ellipse having a long side toward the next digit and a short side toward the bead of the same digit) as seen from the bottom. That is, even if the abacus bead is configured to be an elliptical cylinder, it is possible to easily calculate the abacus similarly. In addition, when performing mass production, it is good also as producing from an elliptic cylinder from the beginning.

実施例1の円柱を用いる変形例
図7のCに示すとおり、上記肉付けを底面から見て円、すなわち算盤珠を円柱となるよう構成しても同様に容易にご破算を行うことが可能である。なお、大量生産を行う場合は、最初から円柱を用いて生産することとしてもよい。
Modified Example Using the Cylinder of Example 1 As shown in FIG. 7C, even if the above-mentioned fleshing is viewed from the bottom, that is, a circle, that is, an abacus bead is configured to be a cylinder, it is possible to calculate easily. . In addition, when performing mass production, it is good also as producing from a cylinder from the beginning.

実施例2
実施例1と同様に、回転防止用芯6を囲むように算盤珠の肉付けを行う。こうすることで、回転防止用芯6や軸3を通した算盤珠を繰り返し利用しても十分な耐久度を備えることができる。ただし、実施例1とは異なり肉付けを算盤珠を完全に覆うまで行い、完全な四角柱となす。なお、大量生産をおこなう場合は最初から四角柱を用いて生産することとしてもよい。
Example 2
In the same manner as in the first embodiment, the abacus bead is made to surround the anti-rotation core 6. By carrying out like this, even if it uses repeatedly the abacus bead which passed the core 6 for rotation prevention, and the axis | shaft 3, sufficient durability can be provided. However, unlike Example 1, fleshing is performed until the abacus bead is completely covered to form a complete quadrangular prism. In addition, when performing mass production, it is good also as producing from a square pillar from the beginning.

そして側面を軸3で貫くことにより算盤を構成する。さらに、回転防止用芯6を軸3に平行となるように側面を貫くことにより、算盤珠が回転することを防止する。   And an abacus is comprised by penetrating a side surface with the axis | shaft 3. FIG. Further, by rotating the anti-rotation core 6 through the side surface so as to be parallel to the shaft 3, the abacus bead is prevented from rotating.

そして、算盤珠の操作面にあたる部分が、図8に示すとおり、凹型となるよう除去する。凹部11は、くぼんでいるのであればどのような形状でもかまわないが、回転楕円体が最も望ましい。指頭ときれいにフィットするからである。   And the part which hits the operation surface of an abacus bead is removed so that it may become a concave shape as shown in FIG. The recess 11 may have any shape as long as it is concave, but a spheroid is most desirable. This is because it fits nicely with the fingertips.

その結果、図9に示すとおり、操作を意図した凹型算盤珠12に指を接触させると、凸型の指と凹型の凹型算盤珠12がしっかりとかみあうことで、指と操作を意図した算盤珠9の接触状態を極めて安定させることが可能となる。これは、通常の算盤珠が双円錐台となっていることから、凸型である指とは互いに点と点でしか接触することができずに不安定となることと対照的である。さらに、回転防止用芯6の存在により凹型算盤珠12が回転することがないので、常に操作面に凹型算盤珠12の凹部11が並ぶことにより、上記効果を恒久的に発揮することが可能である。   As a result, as shown in FIG. 9, when the finger is brought into contact with the concave abacus 12 intended for operation, the convex finger and the concave concave abacus 12 are firmly engaged with each other, so that the abacus intended for the operation with the finger is engaged. The contact state of 9 can be extremely stabilized. This is in contrast to the fact that the normal abacus bead is a double-conical truncated cone, so that the fingers that are convex can only touch each other at points and become unstable. Further, since the concave abacus 12 does not rotate due to the presence of the anti-rotation core 6, the above effect can be exhibited permanently by always having the concave portions 11 of the concave abacus 12 aligned on the operation surface. is there.

実施例2の八角柱を用いる変形例
算盤珠への肉付けを八角柱となるよう図10のAに記載のごとく構成する。そして、八角柱の八角形となる底面が下となるよう、すなわち側面を軸3で貫くことにより算盤を構成する。この構成を採用することで、算盤の状態を初期化する動作である「ご破算」を行う際に、指を滑らかに算盤珠間を移動させることが可能となる。なお、大量生産をおこなう場合は、双円錐台状の算盤珠に肉付けを行うのではなく、最初から八角柱を用いて生産することとしてもよい。
Modification Example Using Octagonal Pole of Example 2 As shown in A of FIG. Then, the abacus is configured by penetrating the side surface with the shaft 3 so that the bottom surface of the octagonal prism becomes the octagonal shape. By adopting this configuration, it is possible to smoothly move the finger between the abacus beads when performing the “breakdown” operation that initializes the abacus state. In addition, when mass production is performed, it is good also as producing from an octagonal column from the beginning instead of fleshing a binocular truncated conical abacus bead.

実施例2の楕円を用いる変形例
図10のBに示すとおり、上記肉付けを底面から見て楕円(隣の桁に向かって長辺、同じ桁の珠に向かって短辺となる楕円。)、すなわち算盤珠を楕円柱となるよう構成しても同様に容易にご破算を行うことが可能である。なお、大量生産を行う場合は、最初から楕円柱を用いて生産することとしてもよい。
Modification Example Using Ellipse of Example 2 As shown in FIG. 10B, an ellipse (an ellipse having a long side toward the adjacent digit and a short side toward the bead of the same digit) as seen from the bottom. That is, even if the abacus bead is configured to be an elliptical cylinder, it is possible to easily calculate the abacus similarly. In addition, when performing mass production, it is good also as producing from an elliptic cylinder from the beginning.

実施例2の円柱を用いる変形例
図10のCに示すとおり、上記肉付けを底面から見て円、すなわち算盤珠を円柱となるよう構成しても同様に容易にご破算を行うことが可能である。なお、大量生産を行う場合は、最初から円柱を用いて生産することとしてもよい。
Modified Example Using the Cylinder of Example 2 As shown in FIG. 10C, even when the above-mentioned fleshing is viewed from the bottom and a circle, that is, an abacus bead is configured to be a cylinder, it is possible to calculate easily. . In addition, when performing mass production, it is good also as producing from a cylinder from the beginning.

参考例及び実施例1、2の回転防止用芯6を用いない変形例1
参考例及び実施例1、2において、回転防止用芯6を軸3に平行となるよう貫くことで算盤珠の回転を防止していたが、回転防止用芯6を用いずに、軸3を角柱とし、算盤珠の軸に接する面も平面で構成する。この構成を採用することにより、軸と算盤珠がしっかりと噛み合い、算盤珠の回転が防止される。
Modification 1 in which the anti-rotation core 6 of the reference example and Examples 1 and 2 is not used
In the reference example and Examples 1 and 2, the rotation of the abacus bead was prevented by penetrating the anti-rotation core 6 so as to be parallel to the axis 3, but without using the anti-rotation core 6, the axis 3 The surface that is a prism and touches the axis of the abacus bead is also a flat surface. By adopting this configuration, the shaft and the abacus bead firmly mesh with each other, and the rotation of the abacus bead is prevented.

参考例及び実施例1、2の回転防止用芯6を用いない変形例2
参考例及び実施例1、2において、回転防止用芯6を軸3に平行となるよう貫くことで算盤珠の回転を防止していたが、軸3を歯車型とし、算盤珠の軸に接する面もこれに噛み合うよう構成する。この構成を採用することにより、軸と算盤珠がしっかりと噛み合い、算盤珠の回転が防止される。
Modification 2 in which the anti-rotation core 6 of the reference example and Examples 1 and 2 is not used
In the reference example and Examples 1 and 2, the rotation of the abacus bead was prevented by penetrating the anti-rotation core 6 so as to be parallel to the shaft 3, but the shaft 3 was a gear type and contacted with the shaft of the abacus bead. The surface is also configured to mesh with this. By adopting this configuration, the shaft and the abacus bead firmly mesh with each other, and the rotation of the abacus bead is prevented.

参考例及び実施例1、2の回転防止用芯6を用いない変形例3
参考例及び実施例1、2において、回転防止用芯6を軸3に平行となるよう貫くことで算盤珠の回転を防止していたが、算盤の底面に板を配置する。この構成を採用することにより、算盤珠底面の平面部分と板が衝突することによって、算盤珠の回転が防止される。
Modification 3 in which the anti-rotation core 6 of the reference example and Examples 1 and 2 is not used
In the reference example and Examples 1 and 2, rotation of the abacus bead was prevented by penetrating the anti-rotation core 6 so as to be parallel to the axis 3, but a plate is disposed on the bottom of the abacus. By adopting this configuration, rotation of the abacus bead is prevented by the collision between the flat portion of the bottom of the abacus bead and the plate.

実施例3
算盤は、軸を用いて算盤珠2を複数個連結した「桁」を、算盤の枠14に並べて固定することで作られている。本実施例では、図11に示すとおり、桁と桁の間にストッパー13を軸に平行に設置して枠に固定する。
Example 3
The abacus is made by arranging and fixing “digits”, which are a plurality of abacus beads 2 connected using an axis, to the abacus frame 14. In the present embodiment, as shown in FIG. 11, a stopper 13 is installed between the girders in parallel to the axis and fixed to the frame.

ストッパー13を設置することで、意図した算盤珠からずれようとした場合、ストッパー13によって自らの指が意図しない珠に接近していることを容易に認識することが可能である。その結果、図11に示すとおり、操作を意図した算盤珠2に指を接触させると、指がストッパー13と接触することによって、意図しない算盤珠に接触する虞がない。   By installing the stopper 13, when trying to deviate from the intended abacus bead, the stopper 13 can easily recognize that its own finger is approaching the unintended bead. As a result, as shown in FIG. 11, when a finger is brought into contact with the abacus 2 intended for operation, there is no possibility that the finger comes into contact with the stopper 13, thereby causing an unintended abacus bead to come into contact.

ストッパー13は、天(1つの珠が設置されているところ)には図11に示すとおり、上部にのみ設置し、地(4つの珠が設置されているところ)は全体にわたって設置する。こうすることで、地については隣接する算盤珠への誤操作を防止しつつ、算盤をご破算するときに、極めてスムーズに天に属する珠を操作することが可能となる。   As shown in FIG. 11, the stopper 13 is installed only on the top (where one pearl is installed), and the ground (where four pearls are installed) is installed throughout. By doing so, it is possible to operate the beads belonging to the heaven very smoothly when the abacus is calculated while preventing the erroneous operation of the adjacent abacus beads on the ground.
