この入力装置では、合成樹脂で形成された１つの部材に４つの変形部が形成され、それぞれの変形部に歪み検出部が取り付けられている。そのため、各歪み検出部を結ぶ配線パターンを、各変形部と重ねて設けることが必要である。この入力装置では、Ｘ方向の歪みを検出する２つのＸ方向検出素子を直列に接続してその両側から電力を与え、２つのＸ方向検出素子の中間からＸ出力を得るようにしており、またＹ方向の歪みを検出する２つのＹ方向検出素子を直列に接続してその両側から電力を与え、２つのＹ方向検出素子の中間からＹ出力を得るように回路を構成するのが一般的である。 In this input device, four deformation portions are formed in one member made of synthetic resin, and a strain detection portion is attached to each deformation portion. For this reason, it is necessary to provide a wiring pattern that connects the strain detection units so as to overlap the deformation units. In this input device, two X-direction detection elements that detect distortion in the X direction are connected in series, power is applied from both sides, and an X output is obtained from the middle of the two X-direction detection elements.

上記各検出素子および前記回路を構成する配線パターンを、それぞれの変形部と重なるように構成すると、その配線回しが複雑になる。また、各変形部を小型に構成しようとすると、狭い領域内に検出素子と配線パターンとを密集させて配置しなくてはならなくなり、配線パターンの形成がいっそう困難になる。 If the wiring patterns constituting each of the detection elements and the circuit are configured so as to overlap with the respective deformed portions, wiring of the wiring becomes complicated. In addition, if each deformed portion is to be configured in a small size, the detection elements and the wiring pattern must be densely arranged in a narrow region, and the formation of the wiring pattern becomes more difficult.

As described above, the four corner portions, which are the thick portions, of the operation member 4 are firmly fixed by being sandwiched between the bottom portion of the storage recess 24 of the lower case 2 and the lower surface of the upper case 3.

動作部材４の前記薄肉部には、上下に貫通する４箇所の貫通穴４５ａ，４５ｂ，４５ｃ，４５ｄが形成されている。図８に示すように、貫通穴４５ａは、前記固定部４２ａの内側に沿ってＬ字形状に形成されている。同様に、貫通穴４５ｂ，４５ｃ，４５ｄは、それぞれ固定部４２ｂ，４２ｃ，４２ｄの内側に沿ってＬ字形状に形成されている。 The thin portion of the operating member 4 is formed with four through holes 45a, 45b, 45c, 45d penetrating vertically. As shown in FIG. 8, the through hole 45a is formed in an L shape along the inside of the fixed portion 42a. Similarly, the through holes 45b, 45c, and 45d are formed in an L shape along the inside of the fixing portions 42b, 42c, and 42d, respectively.

そして、動作部材４の薄肉部には、貫通穴４５ａと貫通穴４５ｂとで挟まれた部分に第１のＸ方向変形部４３ａが形成され、貫通穴４５ｃと貫通穴４５ｄとで挟まれた部分に第２のＸ方向変形部４３ｂが形成されている。また、貫通穴４５ａと貫通穴４５ｃとで挟まれた部分に第１のＹ方向変形部４４ａが形成され、貫通穴４５ｂと貫通穴４５ｄとで挟まれた領域に第２のＹ方向変形部４４ｂが形成されている。 In the thin portion of the operating member 4, the first X-direction deforming portion 43a is formed in the portion sandwiched between the through hole 45a and the through hole 45b, and the portion sandwiched between the through hole 45c and the through hole 45d.

Is formed.

第１のＸ方向変形部４３ａは、貫通穴４５ａと貫通穴４５ｂとで挟まれた領域を意味している。すなわち、図８に示すように貫通穴４５ａと貫通穴４５ｂのＸ２側の縁部を結ぶ線Ｌ１を設定したときに、第１のＸ方向変形部４３ａの中心Ｏ側の端部である基端４３ａ１は前記線Ｌ１上に位置している。また、貫通穴４５ａと貫通穴４５ｂのＸ１側の縁部を結ぶ線Ｌ２を設定したときに、第１のＸ方向変形部４３ａの先端４３ａ２は前記線Ｌ２上に位置している。 The first X-direction deforming portion 43a means a region sandwiched between the through hole 45a and the through hole 45b. That is, as shown in FIG. 8, when a line L1 connecting the X2 side edges of the through hole 45a and the through hole 45b is set, the base end that is the end on the center O side of the first X-direction deforming portion 43a 43a1 is located on the line L1. Further, when a line L2 connecting the X1-side edge of the through hole 45a and the through hole 45b is set, the tip 43a2 of the first X-direction deforming part 43a is located on the line L2.

図８に示すように、第１のＸ方向変形部４３ａの幅寸法Ｗ０は、基端４３ａ１から先端４３ａ２に至る間、均一である。ただし、前記幅寸法が第１のＸ方向変形部４３ａの場所によって相違していてもよい。また、第１のＸ方向変形部４３ａの幅寸法Ｗ０を二分する線は、前記Ｘ軸と一致している。 As shown in FIG. 8, the width dimension W0 of the first X-direction deforming portion 43a is uniform from the proximal end 43a1 to the distal end 43a2. However, the width dimension may be different depending on the location of the first X-direction deforming portion 43a. A line that bisects the width dimension W0 of the first X-direction deforming portion 43a coincides with the X axis.

第２のＸ方向変形部４３ｂは、中心Ｏを挟んで、第１のＸ方向変形部４３ａと対称の位置にあり且つ対称形状である。第１のＹ方向変形部４４ａと第２のＹ方向変形部４４ｂも互いに対称形状であり、これらは、第１のＸ方向変形部４３ａおよび第２のＸ方向変形部４３ｂと同じ寸法を有し且つ同じ形状に形成されている。すなわち、第１のＸ方向変形部４３ａと第２のＸ方向変形部４３ｂおよび第１のＹ方向変形部４４ａと第２のＹ方向変形部４４ｂは、その幅方向を二分する中心線が、直交するＸ軸およびＹ軸に一致しており、またそれぞれの変形部４３ａ，４３ｂ，４４ａ，４４ｂが、中心Ｏに近い側に位置する基端と、中心Ｏから離れて位置する先端を有している。 The second X-direction deforming portion 43b is in a symmetrical position with respect to the first X-direction deforming portion 43a with respect to the center O and has a symmetrical shape. The first Y-direction deforming portion 44a and the second Y-direction deforming portion 44b are also symmetrical with each other, and have the same dimensions as the first X-direction deforming portion 43a and the second X-direction deforming portion 43b. And it is formed in the same shape. That is, the first X-direction deforming portion 43a, the second X-direction deforming portion 43b, the first Y-direction deforming portion 44a, and the second Y-direction deforming portion 44b are orthogonal to each other in the center line that bisects the width direction. The deformed portions 43a, 43b, 44a, and 44b have a proximal end located on the side close to the center O and a distal end located away from the center O. Yes.

図６に示すように、動作部材４の薄肉部の中心には、操作突部４６が一体に形成されている。操作突部４６の軸中心線は、Ｘ軸とＹ軸の交点である中心Ｏに一致している。また、操作突部４６の軸中心線は、Ｘ軸およびＹ軸の双方に直交している。操作突部４６の中心には、動作部材４を上下に貫通する軸芯穴４６ａが形成されている。この軸芯穴４６ａは断面が円形である。 As shown in FIG. 6, an operation protrusion 46 is integrally formed at the center of the thin portion of the operation member 4. The axial center line of the operation protrusion 46 coincides with the center O that is the intersection of the X axis and the Y axis. The axial center line of the operation protrusion 46 is orthogonal to both the X axis and the Y axis. In the center of the operation protrusion 46, an axial hole 46a penetrating the operation member 4 vertically is formed. The shaft hole 46a has a circular cross section.

操作突部４６の本体部分の外周面４６ｂは、図８において破線Φで示すように円柱面である。そして操作突部４６には、前記外周面４６ｂからＸ軸に沿って相反する方向へ突き出る第１のＸ方向突出部４７ａと第２のＸ方向突出部４７ｂが一体に形成されている。また外周面４６ｂからＹ軸に沿って相反する方向へ突き出る第１のＹ方向突出部４８ａと第２のＹ方向突出部４８ｂが一体に形成されている。 The outer peripheral surface 46b of the main body portion of the operation protrusion 46 is a cylindrical surface as indicated by a broken line Φ in FIG. The operation protrusion 46 is integrally formed with a first X-direction protrusion 47a and a second X-direction protrusion 47b that protrude from the outer peripheral surface 46b in opposite directions along the X axis. Further, a first Y-direction projecting portion 48a and a second Y-direction projecting portion 48b projecting in the opposite directions along the Y axis from the outer peripheral surface 46b are integrally formed.

第１のＸ方向突出部４７ａは、第１のＸ方向変形部４３ａの先端４３ａ２に向く先側部４７ａ１を有している。この先側部４７ａ１は、第１のＸ方向変形部４３ａの基端４３ａ１を越えて、先端４３ａ２側に位置している。すなわち、第１のＸ方向突出部４７ａは、その一部が第１のＸ方向変形部４３ａの上に位置している。前記先側部４７ａ１は、曲面形状であり、図８に示すように、先側部４７ａ１と第１のＸ方向変形部４３ａとの境界部は曲線であり、ほぼ円弧曲線である。第１のＸ方向変形部４３ａの基端４３ａ１が位置する前記線Ｌ１から、第１のＸ方向突出部４７ａの先側部４７ａ１までの最大距離は、第１のＸ方向変形部４３ａの長さ寸法（線Ｌ１から線Ｌ２までのＸ軸上の距離）の１／４以上であることが好ましく、さらに好ましくは１／３以上である。 The first X-direction protruding portion 47a has a front side portion 47a1 that faces the tip 43a2 of the first X-direction deforming portion 43a. The front side portion 47a1 is located on the distal end 43a2 side beyond the base end 43a1 of the first X-direction deforming portion 43a. That is, a part of the first X-direction protruding portion 47a is located on the first X-direction deforming portion 43a. The front side portion 47a1 has a curved surface shape, and as shown in FIG. 8, the boundary portion between the front side portion 47a1 and the first X-direction deforming portion 43a is a curved line, and is substantially a circular arc curve. The maximum distance from the line L1 where the base end 43a1 of the first X-direction deforming portion 43a is located to the front side portion 47a1 of the first X-direction projecting portion 47a is the length of the first X-direction deforming portion 43a. It is preferably 1/4 or more, more preferably 1/3 or more of the dimension (distance on the X axis from the line L1 to the line L2).

図８には、前記線Ｌ１上における第１のＸ方向突出部４７ａの幅寸法をＷ１で示している。線Ｌ１上では、第１のＸ方向突出部４７ａの幅寸法Ｗ１が第１のＸ方向変形部４３ａの幅寸法Ｗ０よりも短く、前記線Ｌ１よりもＸ１側においては、第１のＸ方向突出部４７ａの両側（Ｙ１側とＹ２側）に、第１のＸ方向変形部４３ａの一部が位置している。前記幅寸法Ｗ１は前記幅寸法Ｗ０の２／３以下が好ましく、さらに好ましくは１／２以下である。 In FIG. 8, the width dimension of the first X-direction protruding portion 47a on the line L1 is indicated by W1. On the line L1, the width dimension W1 of the first X-direction protruding portion 47a is shorter than the width dimension W0 of the first X-direction deforming portion 43a, and the first X-direction protrusion is closer to the X1 side than the line L1. Part of the first X-direction deforming portion 43a is located on both sides (Y1 side and Y2 side) of the portion 47a. The width dimension W1 is preferably 2/3 or less of the width dimension W0, and more preferably 1/2 or less.

第１のＸ方向突出部４７ａの先側部４７ａ１が、第１のＸ方向変形部４３ａの上に位置しているため、操作突部４６に対してＸ１側へ倒す向きの押圧力が与えられたときに、この押圧力が先側部４７ａ１からその下に位置する第１のＸ方向変形部４３ａに直接に作用し、第１のＸ方向変形部４３ａに曲げ歪みが発生しやすくなる。また、第１のＸ方向突出部４７ａの先側部４７ａ１が曲面形状であるため、操作突部４６に押圧力を与えたときに、先側部４７ａ１と第１のＸ方向変形部４３ａとの境界部で応力を分散させることができ、第１のＸ方向変形部４３ａのいずれか一箇所に過大な応力が集中するの防止でき、亀裂などが発生する故障を防止しやすい。 Since the front side portion 47a1 of the first X-direction projecting portion 47a is located on the first X-direction deforming portion 43a, a pressing force is applied to the operation projecting portion 46 in the direction of tilting toward the X1 side. When this occurs, the pressing force directly acts on the first X-direction deforming portion 43a located below the front side portion 47a1, and bending distortion is likely to occur in the first X-direction deforming portion 43a. Further, since the front side portion 47a1 of the first X-direction protruding portion 47a has a curved surface shape, when a pressing force is applied to the operation protrusion 46, the front side portion 47a1 and the first X-direction deforming portion 43a Stress can be dispersed at the boundary portion, excessive stress can be prevented from being concentrated at any one of the first X-direction deforming portions 43a, and a failure such as a crack can be easily prevented.

さらに、第１のＸ方向突出部４７ａの幅寸法Ｗ１よりも第１のＸ方向変形部４３ａの幅寸法Ｗ０が広く、第１のＸ方向突出部４７ａのＹ１側とＹ２側の両側部に、第１のＸ方向変形部４３ａの一部が存在している。よって、操作突部４６にＸ１方向への押圧力が作用したときに、先側部４７ａ１から第１のＸ方向変形部４３ａの幅寸法Ｗ０の全域に直接に過大な押圧力が作用することがない。すなわち、第１のＸ方向変形部４３ａの先側部４７ａ１の両側が、第１のＸ方向変形部４３ａの一部で補強されていることになり、操作突部４６に押圧力を与えたときに、第１のＸ方向変形部が破損しにくい。 Furthermore, the width dimension W0 of the first X-direction projecting portion 43a is wider than the width dimension W1 of the first X-direction projecting portion 47a, and on both sides of the first X-direction projecting portion 47a on the Y1 side and the Y2 side, A part of the first X-direction deforming portion 43a exists. Therefore, when a pressing force in the X1 direction is applied to the operation protrusion 46, an excessive pressing force may be applied directly from the front side portion 47a1 to the entire width dimension W0 of the first X-direction deforming portion 43a. Absent. That is, both sides of the front side portion 47a1 of the first X-direction deforming portion 43a are reinforced by a part of the first X-direction deforming portion 43a, and a pressing force is applied to the operation projection 46. In addition, the first X-direction deforming portion is not easily damaged.

このように、実施の形態の入力装置１は、操作突部４６がＸ１方向へ押されたときに、第１のＸ方向変形部４３ａに曲げ歪みを発生させやすく、しかも第１のＸ方向変形部４３ａが疲労しにくく、また破損する危険性も少ない。 As described above, in the input device 1 according to the embodiment, when the operation protrusion 46 is pushed in the X1 direction, the first X-direction deforming portion 43a is likely to bend and is deformed. The portion 43a is not easily fatigued and has a low risk of breakage.

第２のＸ方向突出部４７ｂもＸ２側に向く曲面形状の先側部４７ｂ１を有しているが、この先側部４７ｂ１と第２のＸ方向変形部４３ｂとの位置関係は、前記先側部４７ａ１と第１のＸ方向変形部４３ａとの関係と同じである。また、第１のＹ方向突出部４８ａも先側部４８ａ１を有し、第２のＹ方向突出部４８ｂも先側部４８ｂ１を有している。先側部４８ａ１と第１のＹ方向変形部４４ａとの位置関係および先側部４８ｂ１と第２のＹ方向変形部４４ｂとの位置関係も、前記先側部４７ａ１と第１のＸ方向変形部４３ａとの関係と同じである。 The second X-direction projecting portion 47b also has a curved front side portion 47b1 facing the X2 side. The positional relationship between the front side portion 47b1 and the second X-direction deforming portion 43b is the front side portion. This is the same as the relationship between 47a1 and the first X-direction deforming portion 43a. In addition, the first Y-direction protruding portion 48a also has a front side portion 48a1, and the second Y-direction protruding portion 48b also has a front side portion 48b1. The positional relationship between the front side portion 48a1 and the first Y-direction deformation portion 44a and the positional relationship between the front side portion 48b1 and the second Y-direction deformation portion 44b are also the same as those of the front side portion 47a1 and the first X-direction deformation portion. This is the same as the relationship with 43a.

図９（Ａ）と図１０（Ａ）に示す実施の形態では、導電部５１ｂ１と導電部５２ｂ１が、Ｘ出力を得るための導電部であり、導電部５１ｃ１と導電部５２ｃ１が、Ｙ出力を得るための導電部である。また、導電部５２ａ１と導電部５２ａ１が、各検出素子に電力を供給するための第１の導電部と第２の導電部である。 In the embodiment shown in FIGS. 9A and 10A, the conductive portion 51b1 and the conductive portion 52b1 are conductive portions for obtaining the X output, and the conductive portion 51c1 and the conductive portion 52c1 have the Y output.

図１０（Ａ）において破線で示されているように、前記実施の形態の入力装置１が基板に実装されると、この基板の表面に形成されている導電パターン（すなわち入力装置１の外部に設けられた導電体）によって、検出端子５１ｂと検出端子５２ｂとが接続されてＸ出力が得られる。また、基板の表面に形成されている導電パターン（すなわち入力装置１の外部に設けられた導電体）によって、検出端子５１ｃと検出端子５２ｃとが短絡されてＹ出力が得られる。 As shown by a broken line in FIG. 10A, when the input device 1 of the above embodiment is mounted on a substrate, a conductive pattern formed on the surface of the substrate (that is, outside the input device 1). By the provided conductor), the detection terminal 51b and the detection terminal 52b are connected to obtain an X output. Further, the detection terminal 51c and the detection terminal 52c are short-circuited by the conductive pattern (that is, the conductor provided outside the input device 1) formed on the surface of the substrate, and a Y output is obtained.

図９（Ｂ）の比較例は、前記実施の形態における動作部材４と同等の機能を発揮する動作部材４Ａを示している。この動作部材４Ａでは、前記実施の形態の動作部材４と同様に、第１のＸ方向変形部に検出素子５３ｘが設けられ、第２のＸ方向変形部に検出素子５４ｘが設けられている。また第１のＹ方向変形部に検出素子５３ｙが設けられ、第２のＹ方向変形部に検出素子５４ｙが設けられている。 The comparative example of FIG. 9B shows an operating member 4A that exhibits the same function as the operating member 4 in the above-described embodiment. In the operating member 4A, as in the operating member 4 of the above-described embodiment, the detection element 53x is provided in the first X-direction deforming portion, and the detecting element 54x is provided in the second X-direction deforming portion. In addition, the detection element 53y is provided in the first Y-direction deforming portion, and the detection element 54y is provided in the second Y-direction deforming portion.

そして、動作部材４Ａには合計４個の検出端子が設けられている。この比較例では図１０（Ｄ）の回路図に示されるように、４個の検出端子は、「ＶｃｃｏｒＺ」で表される電源端子、「ＧＮＤ」で表される接地端子、さらにＸ出力端子とＹ出力端子である。図９（Ｂ）に示すように、４個の検出端子を設けた例では、図９（Ａ）に示した実施の形態に比べて、動作部材４Ａの底面に設けられる配線パターンの引き回し構造が複雑になる。図９（Ｂ）では、例えば、検出素子５４ｙの左側に２本のパターンを形成し、検出素子５４ｙの右側に１本のパターンを形成することが必要になる。また、検出素子５３ｘの一方の側部に２本のパターンを形成することが必要になる。さらに、図９（Ｂ）に示す例では、各検出素子５３ｘ，５４ｘ，５３ｙ，５４ｙと軸芯穴４６ａとの間にも配線パターンを形成することが必要である。 The operation member 4A is provided with a total of four detection terminals. In this comparative example, as shown in the circuit diagram of FIG. 10D, the four detection terminals are a power supply terminal represented by “Vcc or Z”, a ground terminal represented by “GND”, and an X output. Terminal and Y output terminal. As shown in FIG. 9B, in the example in which four detection terminals are provided, the wiring pattern routing structure provided on the bottom surface of the operation member 4A is compared with the embodiment shown in FIG. 9A. It becomes complicated. In FIG. 9B, for example, it is necessary to form two patterns on the left side of the detection element 54y and to form one pattern on the right side of the detection element 54y. In addition, it is necessary to form two patterns on one side of the detection element 53x. Furthermore, in the example shown in FIG. 9B, it is necessary to form a wiring pattern between each of the detection elements 53x, 54x, 53y, 54y and the shaft core hole 46a.

これに対し、図９（Ａ）に示す実施の形態では、動作部材４に検出端子を合計６本設け、図１０（Ａ）に示すように、入力装置１の外部に設けられた導電体によって、検出端子５１ｂと検出端子５２ｂとを導通させ、且つ検出端子５１ｃと検出端子５２ｃとを接続することにより、動作部材４に形成する配線パターンの引き回しを簡単にできる。よって、図９（Ａ）に示す実施の形態は、図９（Ｂ）に示す例に比べて、動作部材４を小型に形成しやすい。 On the other hand, in the embodiment shown in FIG. 9A, a total of six detection terminals are provided on the operation member 4, and the conductor provided outside the input device 1 as shown in FIG. By connecting the detection terminal 51b and the detection terminal 52b and connecting the detection terminal 51c and the detection terminal 52c, the wiring pattern formed on the operation member 4 can be easily routed. Therefore, in the embodiment shown in FIG. 9A, it is easy to form the operation member 4 in a smaller size than the example shown in FIG. 9B.

図６と図７に示す操作ノブ６は合成樹脂製であり、操作本体部６１は円柱形状である。操作ノブ６の下端の周縁部にはフランジ部６２が突出形成されている。図７に示すように、操作ノブ６には底面から一体に突出する押圧突起６３が設けられており、押圧突起６３の周囲には嵌合凹部６４が形成されている。押圧突起６３は円柱形状であり、図３と図４に示すように、押圧突起６３は、動作部材４の中心Ｏに形成されている軸芯穴４６ａ内にほとんど隙間が無く且つ摺動自在に挿入される。そして、押圧突起６３の下端は、スイッチ機構７を構成している反転部材７３の反転部７３ａに上方から対向する。 The operation knob 6 shown in FIGS. 6 and 7 is made of synthetic resin, and the operation main body 61 has a cylindrical shape. A flange 62 is formed to project from the peripheral edge of the lower end of the operation knob 6. As shown in FIG. 7, the operation knob 6 is provided with a pressing protrusion 63 that protrudes integrally from the bottom surface, and a fitting recess 64 is formed around the pressing protrusion 63. The pressing protrusion 63 has a cylindrical shape. As shown in FIGS. 3 and 4, the pressing protrusion 63 is slidable with almost no gap in the shaft hole 46 a formed at the center O of the operation member 4. Inserted. The lower end of the pressing protrusion 63 faces the reversing portion 73a of the reversing member 73 constituting the switch mechanism 7 from above.

また、前記嵌合凹部６４をＸ−Ｙ平面と平行な面で切断したときの断面形状は、動作部材４の操作突部４６および各突出部４７ａ，４７ｂ，４８ａ，４８ｂの断面形状とほぼ同じである。よって、押圧突起６３が軸芯穴４６ａ内に挿入されると、嵌合凹部６４が、操作突部４６および各突出部４７ａ，４７ｂ，４８ａ，４８ｂとほとんど隙間なく嵌合し、操作ノブ６と操作突部４６とが互いに回動しないように連結される。 Further, the cross-sectional shape when the fitting recess 64 is cut along a plane parallel to the XY plane is substantially the same as the cross-sectional shape of the operation protrusion 46 and the protrusions 47a, 47b, 48a, 48b of the operation member 4. It is. Therefore, when the pressing protrusion 63 is inserted into the shaft hole 46a, the fitting recess 64 is fitted to the operation protrusion 46 and the protrusions 47a, 47b, 48a, 48b with almost no gap, and the operation knob 6 The operation protrusions 46 are connected so as not to rotate with respect to each other.

図６と図７に示すように、上部ケース３は金属板で形成され、平坦な押圧部３１を有している。この上部ケース３が下部ケース２に取り付けられると、押圧部３１の下面が操作部材４の固定部４２ａ，４２ｂ，４２ｃ，４２ｄの表面に密着し、この固定部４２ａ，４２ｂ，４２ｃ，４２ｄが、下部ケース２と上部ケース３との間で動かないように挟まれる。 As shown in FIGS. 6 and 7, the upper case 3 is formed of a metal plate and has a flat pressing portion 31. When the upper case 3 is attached to the lower case 2, the lower surface of the pressing portion 31 is in close contact with the surface of the fixing portions 42a, 42b, 42c, 42d of the operation member 4, and the fixing portions 42a, 42b, 42c, 42d are It is sandwiched between the lower case 2 and the upper case 3 so as not to move.

上部ケース３の中央部には、上方へ向けてリング状に隆起する隆起部３２が形成され、この隆起部３２に円形の開口部３３が形成されている。図３と図４に示すように、上部ケース３が下部ケース２に取り付けられると、前記操作ノブ６の操作本体部６１が、前記開口部３３内を通過して上部ケース３よりも上方へ突出する。また、図３と図４に示すように、操作ノブ６に形成されたフランジ部６２が隆起部３２の内部に位置し、隆起部３２の内部にはフランジ部６２が上下に移動できる移動空間６６が形成される。操作ノブ６はこの移動空間６６の高さ寸法内において、反転部材７３を押圧する方向へ摺動できる。 In the central portion of the upper case 3, a protruding portion 32 that protrudes upward in a ring shape is formed, and a circular opening 33 is formed in the protruding portion 32. As shown in FIGS. 3 and 4, when the upper case 3 is attached to the lower case 2, the operation main body 61 of the operation knob 6 passes through the opening 33 and protrudes upward from the upper case 3. To do. Further, as shown in FIGS. 3 and 4, the flange portion 62 formed on the operation knob 6 is located inside the raised portion 32, and a moving space 66 in which the flange portion 62 can move up and down is located inside the raised portion 32. Is formed. The operation knob 6 can slide in the direction of pressing the reversing member 73 within the height dimension of the moving space 66.

上部ケース３には、対向する２辺からそれぞれ直角に折り曲げられた４つの保持片３４が設けられており、それぞれの保持片３４の先端には固定爪３５が一体に形成されている。下部ケース２の上に反転部材７３と動作部材４および操作ノブ６が設置された後に、上部ケース３が被せられるが、このとき、図１および図２に示すように、保持片３４が、下部ケース２の第３の側面２ｃと第４の側面２ｄの表面に設置される。さらに固定爪３５が下部ケース２の底面２１に向けて折り曲げられる。 The upper case 3 is provided with four holding pieces 34 bent at right angles from two opposite sides, and a fixing claw 35 is integrally formed at the tip of each holding piece 34. After the reversing member 73, the operation member 4 and the operation knob 6 are installed on the lower case 2, the upper case 3 is covered. At this time, as shown in FIG. 1 and FIG. The case 2 is installed on the surfaces of the third side surface 2c and the fourth side surface 2d. Further, the fixing claw 35 is bent toward the bottom surface 21 of the lower case 2.

図５および図６に示すように、下部ケース２の底面２１には、第３の側面２ｃから連続する一対の固定凹部２１ａと、第４の側面２ｄから連続する一対の固定凹部２１ａとが形成されている。図５に示すように、それぞれの固定凹部２１ａの底面２１ａ１は、中心Ｏに向かうにしたがって底面２１から徐々に離れるように傾斜している。 As shown in FIGS. 5 and 6, the bottom surface 21 of the lower case 2 is formed with a pair of fixed recesses 21a continuous from the third side surface 2c and a pair of fixed recesses 21a continuous from the fourth side surface 2d. Has been. As shown in FIG. 5, the bottom surface 21 a 1 of each fixed recess 21 a is inclined so as to gradually move away from the bottom surface 21 toward the center O.

前記上部ケース２の保持片３４から突出する固定爪３５は、前記固定凹部２１ａの内部に押し付けるようにして折り曲げられる。固定凹部２１ａの底面２１ａ１が傾斜面であるために、保持片３４に対して固定爪３５を９０度未満の角度となるように折り曲げることができる。また、折り曲げ後のスプリングバックによって、固定爪３５の表面３５ａが、上部ケース２の底面２１から大きく突出するのを防止できる。よって、組み立て後の入力装置１では、固定爪３５の表面３５ａと下部ケース２の底面２１とがほぼ同一面となる。 The fixing claw 35 protruding from the holding piece 34 of the upper case 2 is bent so as to be pressed into the fixing recess 21a. Since the bottom surface 21a1 of the fixed recess 21a is an inclined surface, the fixed claw 35 can be bent at an angle of less than 90 degrees with respect to the holding piece 34. Moreover, it is possible to prevent the surface 35a of the fixing claw 35 from greatly protruding from the bottom surface 21 of the upper case 2 by the springback after bending. Therefore, in the input device 1 after assembly, the surface 35a of the fixed claw 35 and the bottom surface 21 of the lower case 2 are substantially flush with each other.

この実施の形態の入力装置１は、図１に示すように、操作ノブ６以外の部分が立方体のチップ状であり、リフロー半田工程で、基板などに実装して固定することが可能である。このとき、下部ケース２の底面にほぼ同一面に現れている４つの固定爪３５を、基板の金属膜の部分などに半田付けすることにより、入力装置１を基板上に強固に固定することができる。 As shown in FIG. 1, the input device 1 of this embodiment has a cubic chip shape other than the operation knob 6, and can be mounted and fixed on a substrate or the like in a reflow soldering process. At this time, the input device 1 can be firmly fixed on the substrate by soldering the four fixing claws 35 appearing on the bottom surface of the lower case 2 substantially on the same surface to the metal film portion of the substrate. it can.

前記リフロー半田工程において、下部ケース２の第１の側面２ａに現れている３個の検出端子５１ａ，５１ｂ，５１ｃと、第２の側面２ｂに現れている３個の検出端子５２ａ，５２ｂ，５２ｃが、基板表面に形成された導電パターンに半田付けされる。このとき、図１０（Ａ）に示すように、検出端子５２ａを電源供給パターンに接続し、検出端子５１ａを接地パターンに接続する。また、検出端子５１ｂと検出端子５２ｂをＸ出力パターンに接続し、検出端子５１ｃと検出端子５２ｃをＹ出力パターンに接続する。さらに、第３の側面２ｃに現れているスイッチ接続端子７１ｂと第４の側面２ｄに現れているスイッチ接続端子７２ｂが、基板表面のスイッチ検出パターンに半田付けされる。 In the reflow soldering process, the three detection terminals 51a, 51b, 51c appearing on the first side surface 2a of the lower case 2 and the three detection terminals 52a, 52b, 52c appearing on the second side surface 2b. Is soldered to the conductive pattern formed on the substrate surface. At this time, as shown in FIG. 10A, the detection terminal 52a is connected to the power supply pattern, and the detection terminal 51a is connected to the ground pattern. Further, the detection terminal 51b and the detection terminal 52b are connected to the X output pattern, and the detection terminal 51c and the detection terminal 52c are connected to the Y output pattern. Further, the switch connection terminal 71b appearing on the third side surface 2c and the switch connection terminal 72b appearing on the fourth side surface 2d are soldered to the switch detection pattern on the substrate surface.

この入力装置１では、操作ノブ６に傾き方向の押圧力を与えることで、Ｘ−Ｙ座標データなどを出力することができる。操作ノブ６に傾き方向の押圧力が作用すると、動作部材４では、第１のＸ方向変形部４３ａと第２のＸ方向変形部４３ｂ、ならびに第１のＹ方向変形部４４ａと第２のＹ方向変形部４４ｂの少なくとも１つに曲げ歪みが与えられ、この曲げ歪みが検出素子５３ｘ，５４ｘ，５３ｙ，５４ｙで検出される。 In the input device 1, XY coordinate data and the like can be output by applying a pressing force in the tilt direction to the operation knob 6. When a pressing force in the tilt direction acts on the operation knob 6, in the operation member 4, the first X-direction deforming portion 43 a and the second X-direction deforming portion 43 b, and the first Y-direction deforming portion 44 a and the second Y-direction deforming portion. A bending strain is applied to at least one of the direction deforming portions 44b, and this bending strain is detected by the detection elements 53x, 54x, 53y, and 54y.

図８に示すように、操作突部４６と一体の第１のＸ方向突出部４７ａが、第１のＸ方向変形部４３ａの上に位置しているため、操作ノブ６に作用するＸ１方向への倒れ力により、第１のＸ方向変形部４３ａに大きな歪みを発生させることができる。これは、他の変形部４３ｂ，４４ａ，４４ｂにおいても同じである。 As shown in FIG. 8, since the first X-direction protruding portion 47a integrated with the operation protrusion 46 is located on the first X-direction deforming portion 43a, the X1 direction acting on the operation knob 6 is applied. Due to the tilting force, a large strain can be generated in the first X-direction deforming portion 43a. The same applies to the other deformation portions 43b, 44a, and 44b.

例えば、操作ノブ６によって操作突部４６に対しＸ１方向へ傾かせる押圧力が作用すると、第１のＸ方向変形部４３ａの背面に設けられた検出素子５３ｘに伸び方向の歪みが与えられ、第２のＸ方向変形部４３ｂの背面に設けられた検出素子５４ｘに縮み方向の歪みが与えられる。図１０（Ａ）に示す回路において、検出素子５３ｘと検出素子５４ｘに互いに逆極性の歪みが与えられると、検出素子５３ｘと検出素子５４ｘとの中間の電位が各検出素子５３ｘ，５４ｘの個々の抵抗値の変化に対してほぼ２倍変化する。この中間の電位の変化がＸ出力として与えられる。 For example, when a pressing force for tilting the operation protrusion 46 in the X1 direction is applied by the operation knob 6, the detection element 53x provided on the back surface of the first X-direction deforming portion 43a is strained in the extension direction. The distortion in the contraction direction is given to the detection element 54x provided on the back surface of the second X-direction deforming portion 43b. In the circuit shown in FIG. 10A, when distortions having opposite polarities are given to the detection element 53x and the detection element 54x, the potential between the detection element 53x and the detection element 54x is changed to the individual value of each of the detection elements 53x and 54x. Almost twice as much as the resistance value. This intermediate potential change is given as the X output.

これは、操作突部４６にＹ方向へ倒す押圧力が与えられたときも同じであり、検出素子５３ｙと検出素子５４ｙとに伸びと縮みの逆の歪みが与えられ、検出素子５３ｙと検出素子５４ｙの中間の電位が変化する。この電位の変化がＹ出力として得られる。このようにして出力されるＸ出力とＹ出力から座標入力データを生成することが可能である。 This is the same when a pressing force for tilting in the Y direction is applied to the operation projection 46, and the detection element 53y and the detection element 54y are subjected to reverse strains of expansion and contraction, and the detection element 53y and the detection element The intermediate potential of 54y changes. This change in potential is obtained as a Y output. Coordinate input data can be generated from the X output and Y output that are output in this way.

また、操作ノブ６がその軸方向に沿って垂直に押圧されると、操作ノブ６に一体に設けられた押圧突起６３が、操作部材４の軸芯穴４６ａ内を摺動し、押圧突起６３の下端により、図３と図４などに示される反転部材７３の反転部７３ａが反転して中央接点部７１ａに接触する。これにより中央接点板７１と外側接点板７２とが導通して、スイッチの切換え出力を検出することが可能である。 When the operation knob 6 is pressed vertically along the axial direction thereof, the pressing protrusion 63 provided integrally with the operating knob 6 slides in the shaft hole 46 a of the operating member 4, and the pressing protrusion 63. By the lower end, the reversing portion 73a of the reversing member 73 shown in FIG. 3 and FIG. 4 is reversed and contacts the central contact portion 71a. As a result, the central contact plate 71 and the outer contact plate 72 are brought into conduction, and the switching output of the switch can be detected.

なお、前記実施の形態では、動作部材４の操作突部４６と一体に設けられた、第１のＸ方向突出部４７ａの先側部４７ａ１が曲面形状であり、他の突出部４７ｂ，４８ａ，４８ｂの先側部４７ｂ１，４８ａ１，４８ｂ１も曲面形状である。しかし、これら先側部４７ａ１，４７ｂ１，４８ａ１，４８ｂ１が角張った形状や、断面が台形の形状などであってもよい。 In the above embodiment, the front side portion 47a1 of the first X-direction protruding portion 47a provided integrally with the operation protruding portion 46 of the operating member 4 has a curved shape, and the other protruding portions 47b, 48a, The front side portions 47b1, 48a1, 48b1 of the 48b are also curved. However, the front side portions 47a1, 47b1, 48a1, and 48b1 may have a square shape or a trapezoidal cross section.

By providing the circuit pattern shown in FIG. 10B, the wiring pattern routing structure on the bottom surface 41 of the operation member 4 can be simplified.
