Description

本発明は、シーソースイッチ及び撮像装置に関するものであって、詳しくは操作部材の長さ方向のいずれかの端部を手の指等で押し込む操作を行なった後に、この指等を離すと、この操作部材が中立状態に復帰するシーソースイッチ、及びこのようなシーソースイッチが設けられている撮像装置に関するものである。   The present invention relates to a seesaw switch and an imaging device, and more specifically, after performing an operation of pushing one end of a length direction of an operation member with a finger of a hand and the like, The present invention relates to a seesaw switch in which an operation member returns to a neutral state, and an imaging apparatus provided with such a seesaw switch.

図６は、従来のシーソースイッチ２の構造を示す図である（特許文献１参照）。同図に示すように、操作部材４には、その天板６の裏面における長さ方向の略中央の位置に板状ヒンジ８及びフック１０が垂直に形成されていた。そして、フック１０の先端には鉤部１０ａが形成されていた。   FIG. 6 is a diagram showing the structure of a conventional seesaw switch 2 (see Patent Document 1). As shown in the figure, the operation member 4 has a plate-like hinge 8 and a hook 10 formed vertically at a substantially central position in the length direction on the back surface of the top plate 6. And the hook part 10a was formed in the front-end | tip of the hook 10. As shown in FIG.

また、操作パネル１２には、板状ヒンジ８に対応する２枚のリブ１４と、フック１０のそれぞれに対応する係止孔１６が設けられて、図７に示すように、板状ヒンジ８が２枚のリブ１４の間に挿し込まれ、また、フック１０の先端が係止孔１６に入り込んで、その鉤部１０ａが係止孔１６の段付き部１６ａに引っ掛かることにより、抜けないようになっていた。   Further, the operation panel 12 is provided with two ribs 14 corresponding to the plate-like hinges 8 and locking holes 16 corresponding to the hooks 10 respectively. As shown in FIG. The hook 10 is inserted between the two ribs 14, and the tip of the hook 10 enters the locking hole 16, so that the hook portion 10 a is caught by the stepped portion 16 a of the locking hole 16 so that it does not come off. It was.

図６に示すように、このシーソースイッチ２は、天板６の長さ方向のいずれかの端部を指先で押し込むと、板状ヒンジ８の付け根が弾性変形を生じて、天板６は板状ヒンジ８の付け根を中心に回動するようになっていた。   As shown in FIG. 6, in the seesaw switch 2, when any one end of the top plate 6 in the length direction is pushed with a fingertip, the base of the plate hinge 8 is elastically deformed, and the top plate 6 It was designed to rotate around the root of the hinge 8.

また、操作パネル１２には、天板６の長さ方向における両方の端部のそれぞれの位置に対応して、不図示の接触スイッチが設けられており、この不図示の接触スイッチは、天板６の端部が押し込まれて接触すると電気的に導通するようになっていた。そして、天板６から指が離れると、この天板６は、板状ヒンジ８の弾性力により元の中立状態に戻るので、不図示の接触スイッチから離れ、電気的な導通が解除されるようになっていた。   The operation panel 12 is provided with a contact switch (not shown) corresponding to the positions of both ends in the length direction of the top plate 6. When the end of 6 is pushed in and brought into contact, it is electrically connected. When the finger is removed from the top plate 6, the top plate 6 returns to the original neutral state by the elastic force of the plate-like hinge 8, so that it is separated from the contact switch (not shown) and the electrical continuity is released. It was.

操作部材４のフック１０は、その長さが製造誤差等により短く形成されると、係止孔１６に挿し込んだときに、鉤部１０ａが係止孔１６の段付き部１６ａまで届かずに引っ掛からなくなるため、製造誤差等を見込んで若干長く形成しておく必要があった。
特開平８−１０２２３２号公報 If the length of the hook 10 of the operation member 4 is shortened due to a manufacturing error or the like, the hook portion 10 a does not reach the stepped portion 16 a of the locking hole 16 when inserted into the locking hole 16. In order to eliminate the catch, it was necessary to form it slightly longer in consideration of manufacturing errors and the like.
JP-A-8-102232

しかしながら、前記特許文献１のシーソースイッチ２は製造誤差等を見込んで予めフック１０を若干長く形成する必要があることにより、鉤部１０ａと係止孔１６の段付き部１６ａとの間に隙間を有するようになるため、他のシーソースイッチと同様に、このシーソースイッチ２の操作時にがたつきを感じるという問題があった。   However, in the seesaw switch 2 of Patent Document 1, it is necessary to form the hook 10 slightly longer in advance in consideration of manufacturing errors and the like, so that a gap is formed between the flange portion 10a and the stepped portion 16a of the locking hole 16. Therefore, as with the other seesaw switches, there is a problem that the seesaw switch 2 feels shaky when operated.

そこで本発明は、上記問題点に鑑みて、操作時にがたつきを感じることがないシーソースイッチ、及びこのようなシーソースイッチを用いた撮像装置を提供することを課題とするものである。   Therefore, in view of the above problems, an object of the present invention is to provide a seesaw switch that does not feel rattling during operation, and an imaging apparatus using such a seesaw switch.

以下、本発明に係るシーソースイッチ及び撮像装置の実施の形態について、図面に基づいて具体的に説明する。図１ないし図５は、本発明の一実施の形態に係るシーソースイッチ２０及び撮像装置２２について説明するために参照する図である。   Embodiments of a seesaw switch and an imaging apparatus according to the present invention will be specifically described below with reference to the drawings. 1 to 5 are diagrams which are referred to for explaining a seesaw switch 20 and an imaging device 22 according to an embodiment of the present invention.

本実施の形態に係る撮像装置２２は、図示しないＣＣＤ（Ｃｈａｒｇｅ Ｃｏｕｐｌｅｄ Ｄｅｖｉｃｅ）等の撮像素子を備えて、この撮像素子により取込んだ画像データを記憶しておくことができるようになっている。また、この撮像装置２２は、図示しない撮像系のレンズの位置を調節して望遠又は広角で撮影することができ、その調節をシーソースイッチ２０で行なうようになっている。   The imaging device 22 according to the present embodiment includes an imaging element such as a CCD (Charge Coupled Device) (not shown), and can store image data captured by the imaging element. The imaging device 22 can adjust the position of an imaging system lens (not shown) to take a picture at a telephoto or wide angle, and the adjustment is performed by the seesaw switch 20.

図１に示すように、本実施の形態に係る撮像装置２２の筐体２４は、一方の筐体片２６（第１の軸支部材）と、この筐体片２６に対応する不図示の筐体片等で構成される。シーソースイッチ２０は、この筐体片２６に、操作部材２８及び押さえ部材３８（第２の軸支部材）等が取付けられて構成されるようになっている。   As shown in FIG. 1, the housing 24 of the imaging device 22 according to the present embodiment includes one housing piece 26 (first shaft support member) and a housing (not shown) corresponding to the housing piece 26. It consists of body pieces. The seesaw switch 20 is configured by attaching an operation member 28, a pressing member 38 (second shaft support member) and the like to the casing piece 26.

図２に示すように、操作部材２８は、所定の形状の押下部３０を有しており、この押下部３０の長さ方向における略中央の位置であって幅方向の両端面２８ａのそれぞれから、幅方向に回動軸３２が突出している。この回動軸３２は、突出方向に直角の断面が押下部３０の長さ方向に略平行な直線を有する略半円形に形成されている。また、この押下部３０の長さ方向における両端部のそれぞれには、その厚さ方向に突出する突起２８ｂが形成されている。   As shown in FIG. 2, the operation member 28 includes a pressing portion 30 having a predetermined shape. The operation member 28 is located at a substantially central position in the length direction of the pressing portion 30 from each of both end faces 28 a in the width direction. The rotation shaft 32 protrudes in the width direction. The rotation shaft 32 is formed in a substantially semicircular shape in which a cross section perpendicular to the protruding direction has a straight line substantially parallel to the length direction of the pressing portion 30. In addition, a protrusion 28b protruding in the thickness direction is formed at each of both end portions of the pressing portion 30 in the length direction.

図１に示すように、筐体片２６には、操作部材２８における押下部３０の長さ方向及び幅方向の形状に対応する取付け孔３４が形成されている。また、筐体片２６には、溝部３６が形成されており、この溝部３６は、その長さ方向の一方の端部が取付け孔３４の長さ方向における略中央の位置に開放されて、操作部材２８の回動軸３２に対応する略半円形の断面を有している。この溝部３６は、取付け孔３４の幅方向における両側の位置に形成されており、筐体片２６は操作部材２８の回動軸３２を軸支する軸支部材としての役割を兼ねるようになっている。   As shown in FIG. 1, a mounting hole 34 corresponding to the shape in the length direction and the width direction of the pressing portion 30 in the operation member 28 is formed in the casing piece 26. Further, a groove 36 is formed in the casing piece 26, and this groove 36 has one end in the length direction opened to a substantially central position in the length direction of the mounting hole 34, and the operation is performed. The member 28 has a substantially semicircular cross section corresponding to the rotation shaft 32 of the member 28. The groove portions 36 are formed at positions on both sides in the width direction of the mounting hole 34, and the casing piece 26 also serves as a shaft support member that supports the rotation shaft 32 of the operation member 28. Yes.

操作部材２８は、その回動軸３２が溝部３６に軸支されると、押下部３０がその厚さ方向に取付け孔３４に入り込み、図３に示すように、この押下部３０の一部だけが外側に露出するようになっている。   When the rotary shaft 32 is pivotally supported by the groove portion 36, the operating member 28 has the pressing portion 30 entering the attachment hole 34 in the thickness direction, and only a part of the pressing portion 30 is shown in FIG. Is exposed to the outside.

また、図１に示すように、押さえ部材３８は、樹脂やゴム等の弾性材質で形成されている。この押さえ部材３８は、その一部に板状の押さえ板３８ａが形成され、この押さえ板３８ａ以外の部分は、シーソースイッチ２０以外の他の押しボタン等の一部を構成するようになっており、押さえ板３８ａと押さえ板３８ａ以外の部分は一体的に形成されている。また、本実施の形態とは、異なる別の形態として、押さえ部材３８は、他の部品等を取付けるために用いられていてもよい。   Further, as shown in FIG. 1, the pressing member 38 is formed of an elastic material such as resin or rubber. The presser member 38 is formed with a plate-like presser plate 38a in a part thereof, and a part other than the presser plate 38a constitutes a part of a push button other than the seesaw switch 20 or the like. The portions other than the pressing plate 38a and the pressing plate 38a are integrally formed. Further, as another form different from the present embodiment, the pressing member 38 may be used for attaching other parts and the like.

また、筐体片２６には、押さえ板３８ａの厚さとほぼ同じ高さに突出する突出部４０が、取付け孔３４の長さ方向における両側の近傍の位置に形成されていて、それぞれの突出部４０には、その先端面に開口する雌ネジ４０ａが形成されている。   Further, the housing piece 26 is formed with projecting portions 40 projecting to substantially the same height as the thickness of the pressing plate 38a at positions in the vicinity of both sides in the length direction of the mounting hole 34. 40 is formed with a female screw 40a that opens to the front end surface thereof.

押さえ部材３８の押さえ板３８ａには、操作部材２８の突起２８ｂのそれぞれに対応する突起用孔４２と、筐体片２６の突出部４０のそれぞれに対応する固定用孔４４及び切欠き４６が形成されている。押さえ板３８ａは、固定用孔４４及び切欠き４６が突出部４０に嵌合すると共に、突出部４０の雌ネジ４０ａにネジ結合する雄ネジ４８の頭部と筐体片２６により、厚さ方向に挟まれて固定される。   In the pressing plate 38 a of the pressing member 38, a protrusion hole 42 corresponding to each of the protrusions 28 b of the operation member 28, a fixing hole 44 and a notch 46 corresponding to each of the protruding portions 40 of the housing piece 26 are formed. Has been. The pressing plate 38 a is fitted in the thickness direction by the head portion of the male screw 48 and the housing piece 26, the fixing hole 44 and the notch 46 are fitted in the protruding portion 40 and screwed to the female screw 40 a of the protruding portion 40. It is sandwiched between and fixed.

図４に示すように、操作部材２８における突起２８ｂのそれぞれの先端は、押さえ板３８ａの突起用孔４２を貫通している。そして、それぞれの突起２８ｂの突出方向の近傍には、不図示の接触式スイッチが設けられており、操作部材２８は、その押下部３０の長さ方向における両端部のいずれかが押し込まれると、対応する方の突起２８ｂが、不図示の接触式スイッチに接触して電気的に導通し、不図示の撮像系のレンズの位置が移動して、望遠又は広角の調節が行なわれるようになっている。   As shown in FIG. 4, the tips of the protrusions 28b of the operation member 28 penetrate the protrusion holes 42 of the pressing plate 38a. Then, a contact type switch (not shown) is provided in the vicinity of the protruding direction of each protrusion 28b, and when the operation member 28 is pushed in either one of the end portions in the length direction of the pressing portion 30, The corresponding projection 28b is brought into electrical contact with a contact switch (not shown), and the position of the lens of the imaging system (not shown) is moved so that telephoto or wide-angle adjustment is performed. Yes.

また、図５に示すように、押さえ部材３８は、筐体片２６の溝部３６に軸支された操作部材２８の回動軸３２に対して、その断面における直線の部分に当接するようになっている。   Further, as shown in FIG. 5, the pressing member 38 comes into contact with a linear portion in the cross section with respect to the rotation shaft 32 of the operation member 28 supported by the groove portion 36 of the casing piece 26. ing.

図示しないが、操作部材２８の押下部３０の長さ方向における両端部のいずれかが、ユーザーにより手の指等で押し込まれると、回動軸３２は回動して、この回動軸３２の略半円形の断面における直線の部分の一方の端部が、押さえ板３８ａに押し付けられ、この押さえ板３８ａを湾曲させる。   Although not shown in the drawings, when any one of both end portions of the operation member 28 in the length direction of the pressing portion 30 is pushed by the user with a finger or the like, the rotating shaft 32 rotates, and the rotating shaft 32 One end portion of the straight portion in the substantially semicircular cross section is pressed against the pressing plate 38a, and the pressing plate 38a is curved.

湾曲した押さえ板３８ａは、弾性力により元の状態に戻ろうとするため、回動軸３２の断面における直線の部分の一方の端部を押し戻すように作用する。したがって、ユーザーが手の指等を操作部材２８の押下部３０から離すと、操作部材２８は元の中立位置に戻るようになっている。   The curved pressing plate 38a acts to push back one end portion of the straight portion in the cross section of the rotating shaft 32 in order to return to the original state by the elastic force. Therefore, when the user removes a finger or the like from the pressing portion 30 of the operation member 28, the operation member 28 returns to the original neutral position.

また、操作部材２８の押下部３０の長さ方向における両端部のいずれかが、ユーザーにより手の指等で押し込まれると、回動軸３２が押さえ板３８ａを湾曲させるだけでなく、この回動軸３２にも若干の捩りが生じる。そのため、この回動軸３２に捩りを生じさせる荷重の反力によっても、操作部材２８は元の中立位置に戻るようになっている。   Further, when either one of both end portions of the operation member 28 in the length direction of the pressing portion 30 is pushed by a finger of a hand or the like by the user, the rotation shaft 32 not only curves the holding plate 38a but also this rotation. The shaft 32 is also slightly twisted. Therefore, the operation member 28 is returned to the original neutral position also by the reaction force of the load that causes torsion of the rotating shaft 32.

このような本実施の形態に係るシーソースイッチ２０及び撮像装置２２によれば、回動軸３２が、押さえ板３８ａにより、常に溝部３６に押し付けられるようになっているので、操作時にがたつきを感じることがないため、操作性を向上することができる。   According to the seesaw switch 20 and the imaging device 22 according to the present embodiment, the rotation shaft 32 is always pressed against the groove portion 36 by the pressing plate 38a. Since it does not feel, operability can be improved.

また、押さえ部材３８は、押さえ板３８ａと、この押さえ板３８ａ以外の部分であって、シーソースイッチ２０以外の他の押しボタン等の一部を構成する部材と一体的に形成することができるので、製造費を低減することができる。   Further, the pressing member 38 can be formed integrally with a pressing plate 38a and a member other than the pressing plate 38a and constituting a part of other push buttons other than the seesaw switch 20. Manufacturing costs can be reduced.

また、操作部材２８の回動軸３２は、その断面が略半円形になっているため、押下部３０の長さ方向における両端部のいずれかが手の指等で押し込まれるとき、または、この手の指等を離して操作部材２８が元の中立位置に戻るときには、回動軸３２の回動動作が滑らか（スムーズ）になる。   Further, since the rotary shaft 32 of the operation member 28 has a substantially semicircular cross section, when either one of both end portions in the length direction of the pressing portion 30 is pushed in with a finger of a hand or the like, When the operation member 28 returns to the original neutral position by releasing the finger or the like, the rotation operation of the rotation shaft 32 becomes smooth.

また、湾曲した押さえ板３８ａが、回動軸３２の断面における直線の部分の一方の端部を押し戻す作用により、操作部材２８が元の中立位置に戻るようになっているので、この操作部材２８を元の中立位置に戻すためにクッション材やスプリング等を新たに設ける必要がなく、簡単な構造にすることができる。   In addition, the operation member 28 is returned to the original neutral position by the action of the curved pressing plate 38a pushing back one end of the straight portion in the cross section of the rotation shaft 32. There is no need to newly provide a cushioning material, a spring or the like in order to return to the original neutral position, and a simple structure can be achieved.

なお、本実施の形態においては、図５に示すように、筐体片２６に溝部３６を形成して、操作部材２８の回動軸３２を軸支するようになっていたが、溝部３６を筐体片２６に形成する代わりに、この溝部３６に相当する溝部を押さえ板３８ａに形成すると共に、操作部材２８の回動軸３２について、その突出方向に直角の断面の半円形を略１８０°向きを変えて形成するようにしてもよい。   In the present embodiment, as shown in FIG. 5, the groove portion 36 is formed in the casing piece 26 to support the rotation shaft 32 of the operating member 28. Instead of forming the casing piece 26, a groove corresponding to the groove 36 is formed on the pressing plate 38a, and the rotating shaft 32 of the operating member 28 has a semicircular shape with a cross section perpendicular to the protruding direction of approximately 180 °. You may make it form changing direction.

また、本実施の形態において、回動軸３２は、その突出方向に直角の断面が、半円形に形成されていたが、この半円形の円弧の部分を他の異なる形状に形成するようにしてもよい。例えば、楕円の円弧、曲線、又は、六角形や八角形等のような多角形の一部であって、その角を丸めて形成したもの等であってもよい。このような場合には、溝部３６は、その長さ方向に直角の断面が、回動軸３２の断面に対応するように形成されることはいうまでもない。   In the present embodiment, the rotary shaft 32 has a semicircular cross section perpendicular to the protruding direction. However, the semicircular arc portion is formed in another different shape. Also good. For example, an elliptical arc, a curve, or a part of a polygon such as a hexagon or an octagon may be formed by rounding the corner. In such a case, it is needless to say that the groove portion 36 is formed so that a cross section perpendicular to the length direction thereof corresponds to the cross section of the rotating shaft 32.

また、回動軸３２は、その突出方向に直角の断面の直線が、この直線の両方の端部の中間において連続している必要はなく、例えば、この中間部分に略Ｕ字型の凹部が形成されたり、このような凹部が複数形成されて凹部と直線が交互に断続的に並ぶように形成されたりしてもよい。すなわち、回動軸３２は、その突出方向に直角の断面の直線が、少なくとも、回動時に押さえ板３８ａに押し付けられる両方の端部だけが残るように形成されていればよい。   Further, the rotation shaft 32 does not have to have a straight line having a cross section perpendicular to the projecting direction in the middle between both ends of the straight line. For example, a substantially U-shaped recess is formed in the middle part. It may be formed, or a plurality of such recesses may be formed so that the recesses and straight lines are arranged alternately and intermittently. In other words, the rotation shaft 32 only needs to be formed so that at least both ends that are pressed against the pressing plate 38a at the time of rotation remain in a straight line having a cross section perpendicular to the protruding direction.

また、本実施の形態において、押さえ部材３８は、樹脂やゴム等の弾性材質で形成されるようになっていたが、例えば薄い金属板等で形成されるようになっていてもよい。押さえ部材３８に用いる材質として、樹脂、ゴム又は金属等の中から異なるものを用いるようにすれば、同じ変形量を与えるのに必要な荷重が異なるため、操作部材２８の大きさや回動軸３２の直径等に応じて、適切な材質を選択することができる。   In the present embodiment, the pressing member 38 is formed of an elastic material such as resin or rubber, but may be formed of, for example, a thin metal plate. If a different material from resin, rubber, metal, or the like is used as the pressing member 38, the load required to give the same amount of deformation differs. Therefore, the size of the operation member 28 and the rotation shaft 32 are different. An appropriate material can be selected according to the diameter of the material.

また、本実施の形態に係るシーソースイッチ２０は、撮像装置２２以外の他の電子機器等にも設けることができることはいうまでもない。   Needless to say, the seesaw switch 20 according to the present embodiment can also be provided in electronic devices other than the imaging device 22.
