Description

本発明は、コンピュータのポインティングデバイスとして用いられるマウスに関する。 The present invention relates to a mouse used as a pointing device of a computer.

近年では、グラフィカルユーザインタフェースを採用したオペレーティングシステムが広く用いられている。ポインティングデバイスとしてのマウスの操作は、コンピュータを操作する際に実質的に必須のものとなっており、操作時の疲労感の軽減は主要な課題の一つである。 In recent years, operating systems employing a graphical user interface have been widely used. The operation of a mouse as a pointing device is essentially indispensable when operating a computer, and reducing fatigue during operation is one of the main issues.

例えば特許文献１に開示されているように、疲労感を低減するために、人間の手のひらの角度に合わせて外側に傾斜させたコンピュータマウスなど、種々の形状のマウスが開発されている。 For example, as disclosed in Patent Document 1, in order to reduce the feeling of fatigue, mice having various shapes such as a computer mouse inclined outward according to the angle of a human palm have been developed.

特開平１１−５３１０７号公報Japanese Patent Laid-Open No. 11-53107

しかしながら、上記従来のマウスでは、手を添えてクリックするときの手の形状を自然なものにできても、マウスを移動操作する際の事情が考慮されていない。 However, in the conventional mouse described above, even when the shape of the hand when the user clicks with a hand can be made natural, the circumstances when moving the mouse are not taken into consideration.

本発明は上記実情に鑑みて為されたもので、移動操作時の疲労感を軽減できるマウスを提供することを、その目的の一つとする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mouse that can reduce fatigue during a moving operation.

上記従来例の問題点を解決する本発明は、マウスであって、筐体の上面に隆起部が形成され、当該隆起部の筐体左右方向における頂部は、利用者が筐体を把持した状態で、当該利用者の掌側面であって、第二指基節骨の近位側端と第三指基節骨の近位側端との間に相当する範囲に位置することとしたものである。この隆起部が、利用者の第二指の基部と第三指の基部との間の凹部に嵌まり込むことで、利用者は必要以上の力でマウスを把持することなくマウスの左右方向への移動操作を安定して行うことが可能となり、マウスの移動操作時の疲労感が軽減される。 The present invention that solves the problems of the conventional example described above is a mouse, in which a raised portion is formed on the upper surface of the housing, and the top of the raised portion in the left-right direction of the housing is in a state where the user holds the housing The user's palm side surface is located in a range corresponding to the proximal end of the second finger proximal phalanx and the proximal end of the third finger proximal phalanx. is there. The raised portion fits into the recess between the base of the user's second finger and the base of the third finger, so that the user can move the mouse in the left-right direction without gripping the mouse with excessive force. It is possible to perform the moving operation stably, and the feeling of fatigue during the moving operation of the mouse is reduced.

またここで前記隆起部は、前記利用者が前記筐体を把持した状態で、当該利用者の第二指及び第三指の付け根に相当する位置までその前側端部が延設されていてもよい。さらに前記隆起部は、前記利用者が前記筐体を把持した状態で、当該利用者の掌側面、母指球の短母指屈筋に当接する位置までその後側端部が延設されていてもよい。また前記隆起部は、前記筐体の前後方向における前側よりも後側において左右方向の幅が小さくなるよう形成されていてもよい。利用者の第二指の基部と第三指の基部との間の凹部の位置や形状に合わせることで、隆起部が、利用者の第二指の基部と第三指の基部との間の凹部に嵌まり込みやすくなり、マウスの移動操作時の疲労感軽減に資することとなる。 Further, here, the bulging portion has its front end extended to a position corresponding to the base of the second finger and the third finger of the user in a state where the user grips the housing. Good. Further, the protruding portion may have a rear end extending to a position where the user touches the palm side surface of the user and the short thumb flexor of the thumb ball in a state where the user holds the housing. Good. Moreover, the said protruding part may be formed so that the width | variety of the left-right direction may become smaller in the back side rather than the front side in the front-back direction of the said housing | casing. By matching the position and shape of the recess between the base of the user's second finger and the base of the third finger, the raised portion is between the base of the user's second finger and the base of the third finger. It becomes easy to fit into the concave portion, which contributes to a reduction in fatigue when the mouse is moved.

また本発明の一態様では、前記頂部を含む前記筐体の左右方向断面において、前記隆起部を除く筐体上面部分に外接する円の曲率ｒｂと、前記隆起部に外接する円の曲率ｒｒとの比が、ｒｒ／ｒｂが、0.65以下となるよう、前記隆起部が形成される。また、前記隆起部の左右方向の幅は、２５ミリメートルを超えないこととしてもよい。さらに、前記隆起部は、平面視での前記筐体の前端から筐体の表面に沿って６５ミリメートル乃至８５ミリメートルの位置までその前側端部が延設されてもよい。 In one embodiment of the present invention, in a cross-section in the left-right direction of the casing including the top portion, a curvature rb of a circle circumscribing the upper surface portion of the casing excluding the raised portion, and a curvature rr of a circle circumscribing the raised portion, The raised portion is formed so that the ratio of rr / rb is 0.65 or less. Further, the width of the raised portion in the left-right direction may not exceed 25 millimeters. Furthermore, the front end of the raised portion may extend from the front end of the housing in plan view to a position of 65 mm to 85 mm along the surface of the housing.

さらに、前記利用者が前記筐体を把持した状態で、当該利用者の第二指が到達する範囲に配された第１のボタンと、当該利用者の第三指が到達する位置に配された第２のボタンとを有し、前記第１のボタンと、第２のボタンとは、当該筐体の左右方向における中央側に向かって隆起するよう形成されてもよい。また、前記筐体の少なくとも一方側面には、前記利用者の指を保持する保持部が形成されてもよい。 Furthermore, in a state where the user holds the housing, the first button disposed in a range where the second finger of the user reaches and a position where the third finger of the user reaches. The first button and the second button may be formed so as to protrude toward the center side in the left-right direction of the casing. A holding portion that holds the user's finger may be formed on at least one side surface of the housing.

本発明によると、利用者が必要以上の力でマウスを把持することなくマウスの左右方向への移動操作を安定して行うことが可能となり、マウスの移動操作時の疲労感が軽減される。 According to the present invention, it becomes possible for the user to stably move the mouse in the left-right direction without gripping the mouse with an excessive force, and the feeling of fatigue during the mouse moving operation is reduced.

本発明の実施の形態について図面を参照しながら説明する。なお、本実施の形態の以下の説明や図面において示されたマウス１、またはその各部の大きさやその比、形状は、限定されない限り、適宜変更できるものである。 Embodiments of the present invention will be described with reference to the drawings. It should be noted that the size, ratio, and shape of the mouse 1 shown in the following description of the present embodiment and the drawings, or each part thereof, and the ratio and shape thereof can be changed as appropriate.

本発明の実施の形態に係るマウス１は、図１から図３に例示するように、マウス１の前方側にあって、左ボタン１１と、右ボタン１２と、これらの間に挟まれたクリックホイール１３とを有する操作部１０と、操作部１０から連続する筐体本体部２０とを有するマウスである。図１は、本実施の形態のマウス１の平面図であり、図２は、本実施の形態のマウス１の左側面図であり、図３は本実施の形態のマウス１を利用者が、後に説明する基準位置で把持した状態を表す平面透視図である。 As illustrated in FIGS. 1 to 3, the mouse 1 according to the embodiment of the present invention is on the front side of the mouse 1 and has a left button 11, a right button 12, and a click sandwiched therebetween. It is a mouse having an operation unit 10 having a wheel 13 and a housing body unit 20 continuing from the operation unit 10. FIG. 1 is a plan view of the mouse 1 according to the present embodiment, FIG. 2 is a left side view of the mouse 1 according to the present embodiment, and FIG. 3 illustrates a mouse 1 according to the present embodiment. It is a plane perspective diagram showing the state hold | gripped in the reference position demonstrated later.

なお、図３では利用者の手の骨格が示されている。一般的に人間の指には、末節骨３１，４１、中節骨３２，４２、基節骨３３，４３、中手骨３４，４４が含まれる。本実施の形態において特徴的なことの一つは、この骨格部と骨格部との間隙（平面視において骨がない部分）に嵌まり合う隆起を、マウス１の筐体本体部２０の上面に形成したことである。図３に例示するように、各指の付け根は、基節骨の中間にあたり、基部は基節骨の近位端側にあたる。 FIG. 3 shows the skeleton of the user's hand. Generally, a human finger includes the distal phalanx 31 and 41, the middle phalanx 32 and 42, the proximal phalanx 33 and 43, and the metacarpal bones 34 and 44. One of the characteristic features of the present embodiment is that a ridge that fits in the gap between the skeleton part and the skeleton part (the part having no bone in plan view) is formed on the upper surface of the housing body 20 of the mouse 1. It is formed. As illustrated in FIG. 3, the base of each finger is in the middle of the proximal phalanx, and the base is on the proximal end side of the proximal phalanx.

本実施の形態のマウス１は、通常のマウスと同様に、コンピュータ装置（操作対象装置）２に有線または無線にて接続され、操作対象装置２のポインティングデバイスとして機能する。具体的に、操作対象装置２は、ディスプレイにポインタを表示し、マウス１に対する指示操作の内容に基づいてこのポインタを移動させる。本実施の形態の説明では、ポインタをディスプレイの画面上方に移動させる際にマウス１を移動させる方向を、マウス１の「前方」、ポインタをディスプレイの画面下方に移動させる際にマウス１を移動させる方向を、マウス１の「後方」、ポインタをディスプレイの画面左方に移動させる際にマウス１を移動させる方向を、マウス１の「左」、ポインタをディスプレイの画面右方に移動させる際にマウス１を移動させる方向を、マウス１の「右」とそれぞれ称する。 The mouse 1 according to the present embodiment is connected to a computer device (operation target device) 2 by wire or wirelessly and functions as a pointing device of the operation target device 2, similarly to a normal mouse. Specifically, the operation target device 2 displays a pointer on the display and moves the pointer based on the content of the instruction operation on the mouse 1. In the description of the present embodiment, the direction in which the mouse 1 is moved when the pointer is moved to the upper part of the display screen is “forward” of the mouse 1, and the mouse 1 is moved when the pointer is moved to the lower part of the display screen. The direction is “backward” of the mouse 1, the direction in which the mouse 1 is moved when the pointer is moved to the left of the display screen, the direction of the mouse 1 is moved to the “left”, and the mouse is moved to the right of the display screen. The direction in which 1 is moved is referred to as the “right” of the mouse 1, respectively.

図３（ａ）に例示するように、本実施の形態のマウス１では利用者が、マウス１の筐体本体部２０に掌側の一部を接触させ、左ボタン１１の上面側に第二指の末節が位置するように配置した状態で、基節の一部及び中節の一部をマウスに接触させた状態（いわゆる「かぶせ持ち」の状態）または、指を末節の一部のみ接触させた状態（いわゆる「つかみ持ち」の状態）で、マウス１を把持する。ここではこの把持状態を、基準状態と呼ぶ。この基準状態において、利用者の第二指、第三指の先端（末節）の位置は、図３（ａ）に例示するように、左ボタン１１、右ボタン１２のマウス１の後側端より前側端に近い側に達する。 As illustrated in FIG. 3A, in the mouse 1 of the present embodiment, the user brings a part of the palm side into contact with the housing body 20 of the mouse 1, and the second button 11 is placed on the upper surface side of the left button 11. In a state where the terminal segment of the finger is positioned, a part of the base segment and a part of the middle segment are in contact with the mouse (so-called “carrying” state), or a finger is in contact with only a part of the terminal segment The mouse 1 is gripped in the held state (so-called “gripping” state). Here, this gripping state is referred to as a reference state. In this reference state, the positions of the tips (end nodes) of the second and third fingers of the user are from the rear end of the mouse 1 of the left button 11 and the right button 12, as illustrated in FIG. Reach the side near the front edge.

マウス１は、図３（ｂ）に例示するように、左ボタン１１（または右ボタン１２）が左ボタンカバー１１Ｃ（または右ボタンカバー１２Ｃ）と、左ボタンカバー１１Ｃ（または右ボタン１２Ｃ）の押下を検出する左ボタンスイッチ１１Ｓ（または右ボタンスイッチ１２Ｓ）とを含んで構成され、左ボタンスイッチ１１Ｓ（または右ボタンスイッチ１２Ｓ）がマウス１の前側端に比較的近い位置に配されている。 In the mouse 1, as illustrated in FIG. 3B, the left button 11 (or the right button 12) is pressed by the left button cover 11C (or the right button cover 12C) and the left button cover 11C (or the right button 12C). The left button switch 11S (or right button switch 12S) is detected, and the left button switch 11S (or right button switch 12S) is arranged at a position relatively close to the front end of the mouse 1.

すなわち、基準状態において利用者の第二指、第三指の指先（末節骨の遠位側に相当する）位置は、図３（ｂ）に例示したように、それぞれ左ボタン１１、右ボタン１２の左ボタンスイッチ１１Ｓ、右ボタンスイッチ１２Ｓの配された位置の鉛直上方に相当する左ボタンカバー１１Ｃ、右ボタンカバー１２Ｃの範囲に重なり合うか、または当該範囲を含む範囲であって、平均的な人間の指関節一つ分の幅、長さを有する範囲に重なり合う。 That is, the positions of the fingertips of the user's second and third fingers (corresponding to the distal side of the distal phalanx) in the reference state are the left button 11 and the right button 12 respectively as illustrated in FIG. Of the left button switch 11S and the right button switch 12S are located above the positions of the left button cover 11C and the right button cover 12C corresponding to the upper part of the right button cover 12C. It overlaps the range having the width and length of one finger joint.

また、本実施の形態のマウス１では、筐体本体部２０の上面に、クリックホイール１３の長手方向の後方側延長線上、利用者が基準位置でマウス１を把持したときに、利用者の第二指の基部と第三指の基部との間の凹部に相当する位置に、当該凹部に嵌まり合う形状の隆起部２１が形成されている。 Further, in the mouse 1 according to the present embodiment, when the user holds the mouse 1 at the reference position on the upper surface of the housing main body 20 on the rearward extension line in the longitudinal direction of the click wheel 13, A raised portion 21 having a shape that fits into the recess is formed at a position corresponding to the recess between the base of the second finger and the base of the third finger.

この隆起部２１は、利用者が基準位置でマウス１を把持したときに、そのマウス１の筐体左右方向における頂部（最も高い位置）が、利用者の手の掌側の面であって、第二指基節骨３３の近位側端と第三指基節骨４３の近位側端との間に相当する範囲（図３（ａ））に位置するように形成される。ここで近位とは骨の体幹に近い側を意味し、遠位とは骨の体幹から遠い側を意味する。いずれも解剖学上の用語を用いたものである。 When the user grips the mouse 1 at the reference position, the protruding portion 21 has a top portion (the highest position) in the left-right direction of the housing of the mouse 1 that is a palm side surface of the user's hand, It is formed so as to be located in a corresponding range (FIG. 3A) between the proximal end of the second phalanx 33 and the proximal end of the third phalange 43. Here, the proximal means the side close to the trunk of the bone, and the distal means the side far from the trunk of the bone. Both use anatomical terms.

隆起部２１は、マウス１の筐体本体部２０の他の部分と同じ素材で形成されてもよいし、別の、例えば筐体本体部２０の他の部分よりも比較的柔らかい素材、あるいは比較的硬い素材で形成されてもよい。隆起部２１を、他の部分よりも比較的柔らかい素材で形成する場合、そうでない場合に比べ、隆起部２１をやや大きめに形成してもよい。また、この隆起部２１は、筐体本体部２０に対して着脱可能となっていてもよい。 The raised portion 21 may be formed of the same material as that of the other part of the housing body 20 of the mouse 1, or another material, for example, a material that is relatively softer than the other part of the housing body 20, or the comparison It may be made of a hard material. When the raised portion 21 is formed of a material that is relatively softer than the other portions, the raised portion 21 may be formed slightly larger than when the raised portion 21 is not. Further, the raised portion 21 may be detachable from the housing body 20.

また、平面視における隆起部２１の形状は、図４に例示するように、直線状に延びた長方形状であってもよいし（図４（ａ））、長径がマウス１の前後方向に直線状に延びている長円形であってもよい（図４（ｂ））。さらに、マウス１の筐体の前後方向において前側よりも後側において左右方向の幅Ｗが小さくなるように形成されていてもよい（図４（ｃ））。この形状は、第二指基節骨の中手骨と第三指基節骨の中手骨との間の凹部が、各基節骨の遠位側から近位側へ向けて窄まる形状となっていることに合わせたものである。 Further, the shape of the raised portion 21 in a plan view may be a rectangular shape extending linearly as illustrated in FIG. 4 (FIG. 4A), and the major axis is straight in the front-rear direction of the mouse 1. It may be an oval extending in a shape (FIG. 4B). Furthermore, the width W in the left-right direction may be smaller on the rear side than on the front side in the front-rear direction of the housing of the mouse 1 (FIG. 4C). This shape is such that the recess between the metacarpal bone of the second phalanx and the metacarpal bone of the third phalanx is narrowed from the distal side to the proximal side of each phalanx. It is in line with what has become.

なお、いずれの場合も隆起部２１は、利用者が基準位置でマウス１を把持しつつ、マウス１を左右に移動させたとき、隆起部２１が利用者の第二指の基部と第三指の基部との間の凹部に収まり、かつ、この凹部内で遊び（凹部外周への接触範囲が小さく、マウス１の筐体に対して相対移動してしまい、手の凹部外周から隆起部２１への力の伝達がない状態）がないことが好ましい。そこで、隆起部２１の左右方向の幅Ｗは少なくとも１０ミリメートルを超え、かつ、２５ミリメートルを超えないこととするのが好ましい。この範囲を下回ると、利用者が基準位置でマウス１を把持しつつ、マウス１を左右に移動させたとき、隆起部２１が利用者の第二指の基部と第三指の基部との間の凹部に収まるものの、利用者の掌がマウス１の筐体に対して相対移動する遊びができてしまう。また、この範囲を上回ると、隆起部２１が平均的な手の大きさの利用者の第二指の基部と第三指の基部との間の凹部に収まらないこととなる。なお、平均的な手の大きさは、例えば、産業技術総合研究所が公表している、人体寸法データベース（https://www.dh.aist.go.jp/database/hand/index.html）を参照して、得ることができる。 In any case, when the user moves the mouse 1 to the left and right while holding the mouse 1 at the reference position, the raised portion 21 is connected to the base of the user's second finger and the third finger. In the concave portion between the base portion of the mouse and play in the concave portion (the contact range to the outer periphery of the concave portion is small and moves relative to the housing of the mouse 1 to move from the outer periphery of the concave portion of the hand to the raised portion 21. It is preferable that there is no state in which no force is transmitted. Therefore, it is preferable that the width W in the left-right direction of the raised portion 21 exceeds at least 10 millimeters and does not exceed 25 millimeters. Below this range, when the user moves the mouse 1 left and right while holding the mouse 1 at the reference position, the raised portion 21 is between the base of the user's second finger and the base of the third finger. However, the user's palm can be moved relative to the housing of the mouse 1. Further, when the range is exceeded, the raised portion 21 does not fit in the recess between the base of the second finger and the base of the third finger of the user having an average hand size. The average hand size is, for example, the human body size database (https://www.dh.aist.go.jp/database/hand/index.html) published by the National Institute of Advanced Industrial Science and Technology. To obtain.

さらに、この隆起部２１は、平均的な体格の利用者（手の大きさが平均的である利用者）が基準位置でマウス１を把持したときに、当該利用者の第二指及び第三指の付け根に相当する位置を前側端とし、母指球の短母指屈筋に当接する位置を後側端とする範囲に延設されている。さらにこの前側端と、平面視したときのマウス１の筐体の前方側の端（つまり、平面視で視認できる筐体の上面の前方側の端に相当する点（図３（ｂ）の点Ｐ））からの長さ（上記点Ｐから筐体の上面の表面に沿って測った道のり）Ｌは、６５ミリメートルから８５ミリメートル（より好適には平均的な手の大きさの利用者の第二指の背側長の程度）の範囲内にある。上記距離Ｌがこの範囲より短い（隆起部２１の前側端が筐体前方側端に近い）場合、クリックホイールの操作感に影響することとなり、また、距離Ｌがこの範囲より長い（隆起部２１の前側端が筐体後方端に近い）場合、利用者の手が平均的な大きさの場合に、基準位置でマウス１を把持したとき、隆起部２１が利用者の第二指の基部と第三指の基部との間の凹部よりも手の平に近い側に位置することとなり、第二指の基部と第三指の基部との間の凹部に嵌まり合わない。また、隆起部２１に第二指の基部と第三指の基部との間の凹部を合わせた状態で把持しようとすると、利用者の第二指、第三指が左ボタン１１や右ボタン１２に十分に届かず、クリック操作が難かしくなる。 Furthermore, when the user having an average physique (a user having an average hand size) holds the mouse 1 at the reference position, the raised portion 21 has the second finger and the third finger of the user. A position corresponding to the base of the finger is defined as the front end, and the position in contact with the short thumb flexor of the thumb ball is extended to the rear end. Further, this front end and a front end of the housing of the mouse 1 when viewed in plan (that is, a point corresponding to the front end of the top surface of the casing visible in plan view (the point of FIG. 3B)). P)) (the distance measured from the point P along the surface of the upper surface of the housing) L is 65 mm to 85 mm (more preferably the average hand size of the user) It is within the range of the dorsal length of two fingers). When the distance L is shorter than this range (the front end of the raised portion 21 is close to the front end of the housing), the operational feeling of the click wheel is affected, and the distance L is longer than this range (the raised portion 21). When the mouse 1 is gripped at the reference position when the user's hand is an average size, the raised portion 21 and the base of the second finger of the user It will be located closer to the palm than the recess between the base of the third finger and will not fit into the recess between the base of the second finger and the base of the third finger. Further, when the user tries to grip the raised portion 21 with the concave portion between the base portion of the second finger and the base portion of the third finger, the user's second finger and third finger are left button 11 and right button 12. The click operation is difficult.

また図５は、図１，図２のＶ-Ｖ断面でマウス１を破断した状態を示す断面図である。なお、本来であれば、マウス１の筐体内には回路が内蔵されるのであるが、ここでは説明を容易にするため、回路部を省略して図示している。図５に例示するように、隆起部２１を、頂点を含む、左右方向に延びる破断面で破断したときの断面形状は実質的に円弧をなしていてよい。そしてその頂部（隆起部２１の最も突出した部分）が、利用者が基準位置でマウス１を把持したときに、当該利用者の第二指及び第三指の基部間の凹部に当接し、この隆起部２１が当該凹部に嵌まり込む。 FIG. 5 is a cross-sectional view showing a state in which the mouse 1 is broken along the VV cross section of FIGS. It should be noted that although a circuit is originally built in the housing of the mouse 1, the circuit portion is omitted here for ease of explanation. As illustrated in FIG. 5, the cross-sectional shape of the raised portion 21 when the rupture portion 21 is broken at a fracture surface including the apex and extending in the left-right direction may substantially form an arc. And when the user grips the mouse 1 at the reference position, the top part (the most protruding part of the raised part 21) comes into contact with the concave part between the second finger and the third finger of the user, and this The raised portion 21 is fitted into the concave portion.

ここで隆起部２１に外接する円Ｃ１の曲率（円Ｃ１の半径の逆数）ｒｒ（隆起部２１に外接する円の曲率が場所ごとに異なる場合は、その最大値）と、隆起部２１と同一の面で破断したときの、隆起部２１を除く筐体本体部２０の上面部分に外接する円Ｃ２の曲率（円Ｃ２の半径の逆数）ｒｂとの比Ｒ＝ｒｒ／ｒｂは、0.4以上、0.65以下とする。この比Ｒが上記範囲を下回ると、利用者が基準位置でマウス１を把持しつつ、マウス１を左右に移動させたとき、隆起部２１が利用者の第二指の基部と第三指の基部との間の凹部に収まるものの、利用者の掌がマウス１の筐体に対して相対移動する状態（遊びのある状態）になってしまう。 Here, the curvature of the circle C1 circumscribing the raised portion 21 (the reciprocal of the radius of the circle C1) rr (the maximum value when the curvature of the circle circumscribing the raised portion 21 varies from place to place) is the same as the raised portion 21 The ratio R = rr / rb to the curvature (reciprocal of the radius of the circle C2) rb of the circle C2 circumscribing the upper surface portion of the housing body 20 excluding the raised portion 21 when broken at the surface of 0.65 or less. When the ratio R is less than the above range, when the user moves the mouse 1 to the left and right while holding the mouse 1 at the reference position, the raised portion 21 moves between the base of the user's second finger and the third finger. Although it fits in the recess between the base and the user, the user's palm moves relative to the housing of the mouse 1 (playing state).

また、上記比Ｒが0.65を超えると、隆起の高さが小さくなりすぎ、利用者が基準位置でマウス１を把持して、隆起部２１の頂部が利用者の第二指及び第三指の基部間の凹部に当接させても、隆起部２１全体が凹部に入り込まず、この場合も、利用者が基準位置でマウス１を把持しつつ、マウス１を左右に移動させたとき、利用者の掌がマウス１の筐体に対して相対移動しやすくなってしまう。 If the ratio R exceeds 0.65, the height of the bulge becomes too small, the user grips the mouse 1 at the reference position, and the top of the bulge 21 is the second and third fingers of the user. Even if the ridges 21 are brought into contact with the recesses between the bases, the entire raised portion 21 does not enter the recesses. In this case, when the user moves the mouse 1 to the left and right while holding the mouse 1 at the reference position, the user Is easily moved relative to the housing of the mouse 1.

本実施の形態のマウス１は上記のように、筐体上面の左右方向中央部に背骨の盛り上がりのように隆起した隆起部２１が形成されているため、利用者が被せ持ち（左右のボタン１１，１２にそれぞれ第二指と第三指とを添え、掌を筐体上面に接触させた基準位置）でマウス１を把持したとき、筐体上面に形成された隆起部２１が、利用者の第二指の基部と第三指の基部との間の凹部に嵌まり込む。そして、利用者が基準位置でマウス１を把持しつつ、マウス１を左右に移動させたときに、この隆起部２１に、利用者の第二指基節骨３３または第三指基節骨４３に相当する位置にある掌の部分が当接して、隆起部２１に対して第二指基節骨３３または第三指基節骨４３から、マウス１を左右方向へ移動するための力が加わることとなる。このように本実施の形態のマウス１では、その左右方向中央部において左右方向への移動に必要な力が加えられることとなるので、利用者は必要以上の力でマウス１を把持することなくマウス１の左右方向への移動操作を安定して行うことが可能となり、マウス１の移動操作時の疲労感が軽減される。 As described above, the mouse 1 according to the present embodiment has a raised portion 21 that is raised like a spine at the center in the left-right direction on the upper surface of the housing, so that the user can hold it (the left and right buttons 11 , 12 with a second finger and a third finger respectively, and the mouse 1 is gripped at a reference position where the palm is in contact with the upper surface of the casing), the raised portion 21 formed on the upper surface of the casing is It fits into a recess between the base of the second finger and the base of the third finger. When the user moves the mouse 1 to the left or right while holding the mouse 1 at the reference position, the user's second finger phalange 33 or third finger phalange 43 is placed on the raised portion 21. The portion of the palm at a position corresponding to is abutted, and a force for moving the mouse 1 in the left-right direction is applied to the raised portion 21 from the second finger proximal phalanx 33 or the third finger proximal phalanx 43. It will be. As described above, in the mouse 1 according to the present embodiment, a force necessary for the movement in the left-right direction is applied at the central portion in the left-right direction, so that the user does not hold the mouse 1 with an excessive force. The mouse 1 can be stably moved in the left-right direction, and the feeling of fatigue during the movement operation of the mouse 1 can be reduced.

なお、本実施の形態においては、隆起部２１を単一としている。隆起部２１が一つだけであることで、利用者が自身の第二指の基部と第三指の基部との間の凹部に隆起部２１を嵌め合わせることが容易となる。隆起が多数ある場合、各隆起間の位置によっては利用者の手の形状に合わない場合があるが、隆起部２１を単一とすることで、手の形状や大きさによらず、多くの利用者に適合し得る。 In the present embodiment, the protruding portion 21 is single. Since there is only one raised portion 21, the user can easily fit the raised portion 21 into the recess between the base portion of the second finger and the base portion of the third finger. When there are a large number of ridges, it may not match the shape of the user's hand depending on the position between the ridges. However, by using a single ridge 21, there are many ridges regardless of the shape and size of the hand. Can be adapted to the user.

［変形例１］
ここまでの説明において本実施の形態のマウス１の操作部１０は、従来のマウスと同様の形状で構わないものとしていたが、本実施の形態は、これに限られない。すなわち本実施の形態のマウス１のある例では、左ボタン１１と、右ボタン１２とは、マウス１の筐体の前後方向に延びる中心軸の側（左右方向の中心軸側、つまりクリックホイール１３側）に向かって隆起するよう形成されていてもよい。 [Modification 1]
In the above description, the operation unit 10 of the mouse 1 of the present embodiment may have the same shape as a conventional mouse, but the present embodiment is not limited to this. That is, in an example of the mouse 1 according to the present embodiment, the left button 11 and the right button 12 are the center axis side (the center axis side in the left-right direction, that is, the click wheel 13) extending in the front-rear direction of the housing of the mouse 1. It may be formed so as to protrude toward the side).

図６は、操作部１０におけるマウス１の断面形状の一例を表す断面図である。なお、この図６においても回路部を省略して図示している。図６に例示するように、本実施の形態のある例では、マウス１の左ボタン１１は、マウス１の左側面側よりも中央側の高さが高くなるように形成され、マウス１の右ボタン１２は、マウス１の右側面側よりも中央側の高さが高くなるように形成される。さらに左ボタン１１，右ボタン１２は、下側に凸となる曲面状に形成されてもよい。この場合、クリックホイール１３の形成部分は、左ボタン１１や右ボタン１２より高く隆起していることとなる。なお、このクリックホイール１３の形成部分の隆起の高さは、利用者の手の近位側になるほど、左ボタン１１や右ボタン１２の高さに比べて、その高さの差が小さくなるように形成されてもよく、また、この隆起の幅は、利用者の手の近位側ほど狭くなるように形成されてもよい。 FIG. 6 is a cross-sectional view illustrating an example of a cross-sectional shape of the mouse 1 in the operation unit 10. In FIG. 6, the circuit portion is omitted. As illustrated in FIG. 6, in an example of this embodiment, the left button 11 of the mouse 1 is formed so that the height on the center side is higher than the left side of the mouse 1, The button 12 is formed so that the height on the center side is higher than the right side surface side of the mouse 1. Furthermore, the left button 11 and the right button 12 may be formed in a curved surface that protrudes downward. In this case, the formation portion of the click wheel 13 is raised higher than the left button 11 and the right button 12. It should be noted that the height of the raised portion of the formation portion of the click wheel 13 is such that the closer to the user's hand, the smaller the difference in height compared to the height of the left button 11 or the right button 12. In addition, the width of the ridge may be formed so as to be narrower toward the proximal side of the user's hand.

本実施の形態のこの例によると、基準位置において左ボタン１１に置かれる第二指と、右ボタン１２に置かれる第三指と位置がそれぞれ、クリックホイール１３を挟む位置にそれぞれ決められるので、利用者が基準位置でマウス１を把持したとき、クリックホイール１３の延長線上に形成された隆起部２１が、利用者の第二指の基部と、第三指の基部との間の凹部に嵌まり込みやすくなる。 According to this example of the present embodiment, the position of the second finger placed on the left button 11 and the position of the third finger placed on the right button 12 at the reference position are respectively determined as positions where the click wheel 13 is sandwiched. When the user holds the mouse 1 at the reference position, the raised portion 21 formed on the extension line of the click wheel 13 fits into the recess between the base of the user's second finger and the base of the third finger. It becomes easy to get stuck.

［変形例２］
さらに本実施の形態のマウス１では、筐体の少なくとも一方側面には、利用者の指を保持する保持部を形成してもよい。例えば筐体の左側面に図７に例示する母指（第一指）を保持（指の掌面及び側面それぞれの面において、その少なくとも一部を支持することで指の位置を一定に保つ状態）する形状の保持部２５が形成され、右側面には図８に例示するように、薬指（第四指）を保持する形状の保持部２６が形成される。この例では、利用者が母指と薬指とでマウス１の両側面を挟持しているため、母指及び薬指の間にある示指（第二指）及び中指（第三指）とマウス１との位置が決めやすくなり、利用者が基準位置でマウス１を把持したとき、マウス１の左右方向のほぼ中央部に形成された隆起部２１が、利用者の第二指の基部と、第三指の基部との間の凹部に嵌まり込みやすくなる。なお、この例ではマウス１の両側面に保持部を形成したが、本実施の形態はこれに限られず、保持部が一方側面のみに形成されていてもよい。この場合も、当該保持部と第二指との位置が定まることで隆起部２１が、利用者の第二指の基部と、第三指の基部との間の凹部に嵌まり込みやすくなる。 [Modification 2]
Furthermore, in the mouse 1 of the present embodiment, a holding portion that holds a user's finger may be formed on at least one side surface of the housing. For example, holding the thumb (first finger) illustrated in FIG. 7 on the left side surface of the housing (a state in which the finger position is kept constant by supporting at least a part of each of the palm and side surfaces of the finger) ) And a holding portion 26 having a shape for holding the ring finger (fourth finger) is formed on the right side surface as illustrated in FIG. In this example, since the user holds both sides of the mouse 1 with the thumb and ring finger, the index finger (second finger) and middle finger (third finger) between the thumb and ring finger, the mouse 1 and When the user grips the mouse 1 at the reference position, the raised portion 21 formed at the substantially central portion in the left-right direction of the mouse 1 is the base of the second finger of the user and the third It becomes easy to fit into the recess between the base of the finger. In this example, the holding portions are formed on both side surfaces of the mouse 1, but the present embodiment is not limited to this, and the holding portions may be formed only on one side surface. Also in this case, since the positions of the holding portion and the second finger are determined, the raised portion 21 is easily fitted into the recess between the base portion of the user's second finger and the base portion of the third finger.

［左利き用マウスの例］
なお、ここまでの説明は右利き用のマウス１を例として説明してきたが、左利き用のマウス１では、ここまでの説明における左右が逆となるだけで、他の点は右利き用マウス１と同様である。 [Example of left-handed mouse]
In the above description, the right-handed mouse 1 has been described as an example. However, in the left-handed mouse 1, only the left and right in the above description are reversed, and the other points are the right-handed mouse 1. It is the same.

［マウスの上面に左右方向の傾斜が形成されている例］
また、マウス１の上面が、左右方向に傾斜している場合、例えばマウス１の筐体を、左右方向に伸びる線で破断したとき、その破断面におけるマウス１の上面が、左右方向に傾斜しており、クリックホイール１３があるときにその回転軸がマウス１の底面に対して水平でない場合は、隆起部２１の隆起方向は、このマウス１の隆起部２１の形成位置での筐体の上面の法線方向、または左ボタン１１や右ボタン１２の移動方向（押下方向）に平行な向きとしてもよい。 [Example of left and right slopes formed on the top surface of the mouse]
In addition, when the upper surface of the mouse 1 is inclined in the left-right direction, for example, when the housing of the mouse 1 is broken along a line extending in the left-right direction, the upper surface of the mouse 1 in the fracture surface is inclined in the left-right direction. If the rotation axis of the click wheel 13 is not horizontal with respect to the bottom surface of the mouse 1, the protruding direction of the protruding portion 21 is the upper surface of the housing at the position where the protruding portion 21 of the mouse 1 is formed. Or a direction parallel to the moving direction (pressing direction) of the left button 11 or the right button 12.
