When a force is applied, the operation knob is displaced in the direction of sunk on the front surface or the front surface, and the protrusion amount of the operation knob from the front surface or the front surface is less than a predetermined value such as 9.5 mm described above. It is required to be.

前述した規制を満足するために、従来から種々の操作ノブの支持構造１００（図１に示し、例えば、特許文献１参照）が用いられてきた。図１に例示された操作ノブの支持構造１００は、前述した電子機器の機器本体１０１に対して操作ノブ１０２を変位自在に支持する支持部１０３と、脆弱部１０４とを備えている。操作ノブ１０２は、有底筒状に形成されたノブ本体１０５と、当該ノブ本体１０５の底部から立設した円筒状の筒部１０６とを一体に備えている。また、電子機器は、前述したインパネに取り付けられると、機器本体１０１の前面１０１ａがインパネの表面と平行になる。   In order to satisfy the above-described regulations, various operation knob support structures 100 (shown in FIG. 1, see, for example, Patent Document 1) have been used. The operation knob support structure 100 illustrated in FIG. 1 includes a support portion 103 that supports the operation knob 102 so as to be displaceable with respect to the device main body 101 of the electronic device described above, and a fragile portion 104. The operation knob 102 is integrally provided with a knob main body 105 formed in a bottomed cylindrical shape and a cylindrical cylindrical portion 106 erected from the bottom of the knob main body 105. In addition, when the electronic device is attached to the above-described instrument panel, the front surface 101a of the device main body 101 is parallel to the surface of the instrument panel.

支持部１０３は、前記機器本体１０１内に収容されかつ当該機器本体１０１の前面１０１ａと平行に固定された印刷配線板１０７と、当該印刷配線板１０７に実装されたスイッチ装置１０８とを備えている。スイッチ装置１０８は、印刷配線板１０７に固定されたスイッチ本体１０９と、このスイッチ本体１０９から突出しかつこのスイッチ本体１０９に対して回転する方向や突没する方向に変位自在に設けられた操作子１１０とを備えている。操作子１１０は、円柱状に形成され、前述した筒部１０６内に圧入されて、操作ノブ１０２が取り付けられている。このため、操作ノブ１０２は、操作子１１０によりその軸芯回りに回転する方向や前面１０１ａに対して突没する方向に変位自在即ち機器本体１０１に対して変位自在となっている。また、操作ノブ１０２は、機器本体１０１の前面１０１ａに対して直交した格好となる。   The support unit 103 includes a printed wiring board 107 housed in the device main body 101 and fixed in parallel with the front surface 101 a of the device main body 101, and a switch device 108 mounted on the printed wiring board 107. . The switch device 108 includes a switch main body 109 fixed to the printed wiring board 107, and an operation element 110 that protrudes from the switch main body 109 and is displaceable in a rotating direction and a retracting direction with respect to the switch main body 109. And. The operation element 110 is formed in a columnar shape, and is press-fitted into the above-described cylinder portion 106, and the operation knob 102 is attached thereto. For this reason, the operation knob 102 is displaceable with respect to the device main body 101 in a direction that rotates around its axis by the operation element 110 and a direction that protrudes and retracts from the front surface 101a. Further, the operation knob 102 looks orthogonal to the front surface 101a of the device main body 101.

脆弱部１０４は、操作ノブ１０２の底部から間隔をあけ、筒部１０６の内周面から突出した突部１１１を備えている。脆弱部１０４は、操作ノブ１０２に対して、前述した方向の予め定められた力が作用すると、突部１１１と筒部１０６の内周面との間が破断することで、操作ノブ１０２の機器本体１０１の前面１０１ａからの突出量を前述した予め定められた値以下とするようになっている。
特開２００６−２１０２８８号公報 The fragile portion 104 includes a protrusion 111 that is spaced from the bottom of the operation knob 102 and protrudes from the inner peripheral surface of the cylindrical portion 106. When the predetermined force in the above-described direction acts on the operation knob 102, the fragile portion 104 breaks between the protrusion 111 and the inner peripheral surface of the cylindrical portion 106, so that the device of the operation knob 102 The amount of protrusion from the front surface 101a of the main body 101 is set to be equal to or less than the predetermined value described above.
JP 2006-210288 A

前述した自動車のインパネは、当該自動車のデザイン上の多種多様性により、前記表面が鉛直方向と平行ではなく、上方に向かうにしたがって自動車の前方に向かう方向に傾斜していることが多い。このように表面が傾斜したインパネに電子機器を取り付けると、勿論、電子機器の機器本体１０１の前面１０１ａも、前述したインパネの表面と平行になって傾いてしまう。すると、勿論、スイッチ装置１０８の操作子１１０の長手方向も、自動車の前後方向（水平方向）に対して傾いてしまう。   The above-mentioned vehicle instrument panel is often inclined in the direction toward the front of the vehicle as it goes upward, due to the diversity of the design of the vehicle, and the surface is not parallel to the vertical direction. When an electronic device is attached to the instrument panel whose surface is inclined in this way, of course, the front surface 101a of the device main body 101 of the electronic device is also inclined in parallel with the surface of the instrument panel described above. Then, of course, the longitudinal direction of the operation element 110 of the switch device 108 is also inclined with respect to the front-rear direction (horizontal direction) of the automobile.

このため、前述した方向の力を操作ノブ１０２に加えると、まず、図２に示すように、操作ノブ１０２の底部の表面が鉛直方向と平行になるように、当該操作ノブ１０２がスイッチ装置１０９に対して傾いてしまう。この場合、機器本体１０１の前面１０１ａが鉛直方向と平行な状態よりも前述した脆弱部１０４が破断しにくくなって、操作ノブ１０２の前述した方向の前述した予め定められた力を加えても、脆弱部１０４が破断せずに、操作ノブ１０２の突出量が前述した予め定められた値以下とならないおそれがあった。   For this reason, when the force in the above-described direction is applied to the operation knob 102, first, as shown in FIG. 2, the operation knob 102 is moved to the switch device 109 so that the bottom surface of the operation knob 102 is parallel to the vertical direction. Will be inclined to. In this case, the fragile portion 104 described above is less likely to break than the state in which the front surface 101a of the device main body 101 is parallel to the vertical direction, There is a possibility that the fragile portion 104 does not break and the protruding amount of the operation knob 102 does not fall below the predetermined value described above.

したがって、本発明の目的は、例えば、表面が傾いたインパネに本体部が取り付けられた際に、予め定められた力が作用すると、脆弱部が破断して、操作ノブが没することを可能とする操作ノブの支持構造及び該操作ノブの支持構造を備えた電子機器を提供することにある。   Therefore, an object of the present invention is that, for example, when a predetermined force is applied when the main body is attached to an instrument panel whose surface is inclined, the weakened portion is broken and the operation knob can be sunk. It is an object of the present invention to provide an operation knob support structure and an electronic apparatus including the operation knob support structure.

前述した課題を解決し目的を達成するために、請求項１に記載の本発明の操作ノブの支持構造は、鉛直方向に対して傾いて配置される本体部の外表面から突出しかつ当該本体部に対して変位自在に設けられた操作ノブと、前記操作ノブを支持する支持部材と、前記支持部材を設置しかつ一端部が前記本体部に取り付けられた取付部材と、前記支持部材と前記操作ノブとの間に設けられかつ前記操作ノブが水平方向に沿って前記外表面に向かって予め定められた所定の力を超えた力で押圧されると破断する脆弱部と、前記本体部に設けられ、かつ前記取付部材の他端部に係止するとともに、前記操作ノブが水平方向に沿って前記外表面に向かって前記脆弱部が破断する前記所定の力よりも弱い第２の所定の力を超えた力で押圧されると前記他端部の係止を解除する係止部と、前記係止部の前記他端部の係止が解除された際に、前記取付部材及び本体部のうち一方に接触して、前記操作ノブの端面が鉛直方向と平行となる状態に、前記取付部材を位置付けるストッパ部材と、を備えたことを特徴としている。   In order to solve the above-described problems and achieve the object, the operation knob support structure according to the first aspect of the present invention projects from the outer surface of the main body portion arranged to be inclined with respect to the vertical direction and the main body portion.

以下、本発明の一実施形態を説明する。本発明の一実施形態にかかる操作ノブの支持構造は、操作ノブを支持した支持部材を一端部が本体部に取り付けられた取付部材に設置し、支持部材と操作ノブとの間に脆弱部を設けているとともに、取付部材の他端部を係止部によって本体部に取り付けている。そして、操作ノブが水平方向に沿って本体部の外表面に向かって脆弱部の破断する所定の力よりも弱い第２の所定の力で押圧されると、係止部の係止が解除されるとともに、ストッパ部材によって操作ノブの端面が鉛直方向と平行な状態に支持部材を位置付けられる。   Hereinafter, an embodiment of the present invention will be described. The support structure of the operation knob according to one embodiment of the present invention is such that a support member that supports the operation knob is installed on an attachment member having one end attached to the main body, and a fragile portion is provided between the support member and the operation knob. In addition, the other end of the attachment member is attached to the main body by a locking part. Then, when the operation knob is pressed with a second predetermined force that is weaker than the predetermined force that breaks the fragile portion toward the outer surface of the main body portion along the horizontal direction, the locking portion is unlocked. At the same time, the stopper member can position the support member so that the end surface of the operation knob is parallel to the vertical direction.

こうすることで、脆弱部が破断する前に、操作ノブの端面が鉛直方向と平行な状態に位置付けられて、当該脆弱部が破断する際には、操作ノブが支持部材に対して傾くことがない。よって、脆弱部が破断する際には、端面が鉛直方向と平行な操作ノブに水平方向に沿って本体部の外表面に向かって押圧する力が確実に作用することになる。したがって、脆弱部が、予め定められた所定の力が操作ノブに作用すると確実に破断することになり、本体部からの突出量が予め定められた値以下となるまで操作ノブが確実に本体部に対して没することになる。   By doing so, the end face of the operation knob is positioned in a state parallel to the vertical direction before the fragile portion breaks, and when the fragile portion breaks, the operation knob may be inclined with respect to the support member. Absent. Therefore, when the fragile portion breaks, a force that presses the end surface of the operation knob parallel to the vertical direction toward the outer surface of the main body portion along the horizontal direction surely acts. Therefore, the fragile portion is surely broken when a predetermined predetermined force acts on the operation knob, and the operation knob is surely operated until the amount of protrusion from the main body portion becomes a predetermined value or less. Will die against.

取付部材の一端部が他端部よりも前述した押圧される力の前方側に配置されていても良い。この場合、係止部の係止が解除されると、取付部材が一端部を中心として他端部が一端部と鉛直方向に並ぶ位置に向かって回転することになる。このため、脆弱部が破断する際に、操作ノブが支持部材に対して傾くことなく、端面が鉛直方向と平行な操作ノブに水平方向に沿って本体部の外表面に向かって押圧する力がより確実に作用することになる。   One end portion of the attachment member may be arranged on the front side of the pressing force described above than the other end portion. In this case, when the locking of the locking portion is released, the attachment member rotates about the one end portion toward the position where the other end portion is aligned with the one end portion in the vertical direction. For this reason, when the fragile portion breaks, the operation knob is not inclined with respect to the support member, and the force that presses the end surface of the operation knob parallel to the vertical direction along the horizontal direction toward the outer surface of the main body portion. It will work more reliably.

取付部材をその一端部を中心として回転自在に支持するヒンジ部を設けても良い。この場合、係止部の取付部材の他端部の係止が解除されると、取付部材がその一端部を中心として確実に回転する。このため、脆弱部が破断する際に、操作ノブが支持部材に対して傾くことなく、端面が鉛直方向と平行な操作ノブに水平方向と平行でかつ本体部の外表面に向かって押圧する力がより一層確実に作用することになる。   You may provide the hinge part which supports an attachment member rotatably centering on the one end part. In this case, when the locking of the other end portion of the mounting member of the locking portion is released, the mounting member reliably rotates around the one end portion. For this reason, when the fragile portion is broken, the operation knob is not inclined with respect to the support member, and the end surface is pressed against the operation knob parallel to the vertical direction in parallel to the horizontal direction and toward the outer surface of the main body portion. Will act even more reliably.

さらに、本発明では、前述した操作ノブの支持構造を備えた電子機器としても良い。この場合、電子機器は、前述した操作ノブの支持構造を備えているので、脆弱部が、予め定められた所定の力が操作ノブに作用すると確実に破断することになり、操作ノブが本体部からの突出量が予め定められた値以下となるまで確実に本体部に対して没することになる。   Furthermore, in the present invention, an electronic apparatus having the above-described operation knob support structure may be used. In this case, since the electronic device includes the above-described operation knob support structure, the weakened portion is surely broken when a predetermined force is applied to the operation knob. It will be surely immersed in a main-body part until the protrusion amount from becomes below a predetermined value.

An AV (Audio-Visual) device 1 as an electronic device according to an embodiment of the present invention includes an automobile instrument panel (indicated by a two-dot chain line in FIG. 3 and hereinafter referred to as an instrument panel) P as a moving body. It is attached to. Hereinafter, an arrow Y that is parallel to the surface of a CD or MD, which will be described later, and parallel to the direction in which the CD or MD is loaded or unloaded is referred to as a depth direction. The arrow X is called the width direction, and the arrow Z orthogonal to both the depth direction Y and the width direction X is called the thickness direction. Further, the surface Pa of the instrument panel P is inclined with respect to the vertical direction so as to go forward of the automobile as it goes upward.

ＡＶ機器１は、図３に示すように、本体部としてのケース２と、再生装置としてのＣＤ（Compact Disk）プレーヤ３と、再生装置としてのＭＤ（Mini disc）プレーヤ４と、ラジオ放送を受信するＡＭ／ＦＭチューナ５と、表示部６と、操作部７とを備えている。   As shown in FIG. 3, the AV device 1 receives a case 2 as a main unit, a CD (Compact Disk) player 3 as a playback device, an MD (Mini disc) player 4 as a playback device, and a radio broadcast.

The case 2 is attached to the instrument panel P described above with the front panel 18a attached to the front side of the case body 18b in FIG. In the case 2, the case main body 18b is attached to the instrument panel P described above, the front panel 18a is exposed to the outside, and faces the passenger (also referred to as a user). A front surface 2a as an exposed outer surface of the front panel 18a located on the front side in FIG. 1 of the case 2 is parallel to the surface Pa of the instrument panel P when the case 2 is attached to the instrument panel P. For this reason, the front surface 2a is inclined with respect to the vertical direction in a state where the angle with the vertical direction is predetermined.

また、本発明の電子機器としてのＡＶ機器１は、予めインパネＰに取り付けられる自動車の車種が定められているので、インパネＰの表面Ｐａ及びフロントパネル１８ａの前面２ａの鉛直方向に対する角度は、予め定められている。また、フロントパネル１８ａの前面２ａには、ＣＤ用挿入口８と、ＭＤ用挿入口９と、操作部用孔１３とが開口している。   In the AV apparatus 1 as the electronic apparatus of the present invention, since the vehicle type of the automobile to be attached to the instrument panel P is determined in advance, the angles of the surface Pa of the instrument panel P and the front surface 2a of the front panel 18a with respect to the vertical direction are determined in advance. It has been established. Further, a CD insertion slot 8, an MD insertion slot 9, and an operation section hole 13 are opened in the front surface 2a of the front panel 18a.

ＣＤ用挿入口８は、内側にＣＤを通して、該ＣＤをケース２即ちＣＤプレーヤ３に出し入れする。ＭＤ用挿入口９は、内側にＭＤを通して、該ＭＤをケース２即ちＭＤプレーヤ４に出し入れする。操作部用孔１３は、前記フロントパネル１８ａを貫通している。操作部用孔１３即ちフロントパネル１８ａは、操作部７の後述する操作ボタン１１を収容するとともに、前記前面２ａに対して直交する奥行き方向Ｙに沿って、当該操作ボタン１１を移動自在に支持する。   The CD insertion slot 8 allows the CD to pass into and out of the case 2, that is, the CD player 3 through the CD inside. The MD insertion port 9 passes the MD inward, and puts the MD in and out of the case 2, that is, the MD player 4. The operation portion hole 13 passes through the front panel 18a. The operation portion hole 13, that is, the front panel 18a accommodates an operation button 11 to be described later of the operation portion 7, and supports the operation button 11 movably along a depth direction Y orthogonal to the front surface 2a. .

また、ケース２には、図４に示すように、孔１４と、支持部１６と、内部壁１７とが設けられている。孔１４は、前面２ａに開口し、かつ平面形状が丸形に形成されている。支持部１６は、内側筒部１９と、ヒンジ支持部２０とを備えている。内側筒部１９は、円筒状に形成されかつ孔１４の内縁部からケース２の内側に向かって立設している。   Further, as shown in FIG. 4, the case 2 is provided with a hole 14, a support portion 16, and an inner wall 17.

ストッパ部材２４は、図示例では、内部壁１７の基板ホルダ３２のホルダ本体３５の他端部３５ｂと奥行き方向Ｙに沿って並ぶ位置に設けられ、かつ内部壁１７から前面２ａに向かって突に形成されている。また、ストッパ部材２４は、ケース２即ちＡＶ機器１がインパネＰに取り付けられると、その先端部がヒンジ支持部２０の孔２１と鉛直方向に並ぶ位置に設けられている。   In the illustrated example, the stopper member 24 is provided at a position aligned with the other end portion 35b of the holder body 35 of the substrate holder 32 of the inner wall 17 along the depth direction Y, and protrudes from the inner wall 17 toward the front surface 2a. Is formed. Further, when the case 2, that is, the AV device 1 is attached to the instrument panel P, the stopper member 24 is provided at a position where the tip end portion is aligned with the hole 21 of the hinge support portion 20 in the vertical direction.

ストッパ部材２４は、操作ノブ１５が自動車の前後方向（水平方向）に沿って前面２ａに向かって押圧されて、係止部２２，３７の係止爪２７，３９の係止が互いに解除されると、基板ホルダ３２のホルダ本体３５の他端部３５ｂ即ち支持部２３と接触して、ホルダ本体３５、印刷配線板３３及び操作ノブ１５の外表面２８ａが鉛直方向と平行になる状態に基板ホルダ３２を位置付ける。   In the stopper member 24, the operation knob 15 is pressed toward the front surface 2a along the front-rear direction (horizontal direction) of the automobile, and the locking claws 27, 39 of the locking portions 22, 37 are unlocked from each other. And the other end 35b of the holder main body 35 of the substrate holder 32, that is, the support 23, and the holder main body 35, the printed wiring board 33, and the outer surface 28a of the operation knob 15 are parallel to the vertical direction. 32 is positioned.

脆弱部２５は、操作ノブ１５の底部２８から間隔をあけ、筒部３１の内周面から突出した突部４２を備えて、図示例では、操作ノブ１５に一体に設けられている。突部４２は、スイッチ装置３４の操作子４１の先端面上に重ねられる。このように、突部４２が筒部３１の内周面から突出して設けられてスイッチ装置３４の操作子４１の先端面上に重ねられることを、本発明では、脆弱部２５が、スイッチ装置３４と操作ノブ１５の間に設けられているという。脆弱部２５は、操作ノブ１５が自動車の前後方向（水平方向）に沿って前面２ａに向かって、予め定められた所定の力を超えた力（図５中に矢印Ｆで示す）で押圧されると、突部４２が筒部３１の内周面から破断する。そして、脆弱部２５は、筒部３１内を操作子４１が摺動して、操作子４１が底部２８に近づくのを許容する。こうして、脆弱部２５は、操作ノブ１５のケース２の前面２ａからの突出量を前述した予め定められた値以下となるように、当該操作ノブ１５が孔１４即ちフロントパネル１８ａの前面２ａに没する方向に変位することを許容する。このように、脆弱部２５は、突部４２が筒部３１の内周面から破断することで、操作ノブ１５が孔１４内即ちフロントパネル１８ａの前面２ａに没することを許容する。   The fragile portion 25 includes a protrusion 42 that is spaced from the bottom 28 of the operation knob 15 and protrudes from the inner peripheral surface of the cylindrical portion 31, and is provided integrally with the operation knob 15 in the illustrated example. The protrusion 42 is overlaid on the distal end surface of the operation element 41 of the switch device 34. As described above, the protrusion 42 is provided so as to protrude from the inner peripheral surface of the cylindrical portion 31 and is superimposed on the distal end surface of the operation element 41 of the switch device 34. It is said that it is provided between the operation knob 15. The fragile portion 25 is pressed by a force (indicated by an arrow F in FIG. 5) in which the operation knob 15 exceeds a predetermined force toward the front surface 2a along the longitudinal direction (horizontal direction) of the automobile. Then, the protrusion 42 is broken from the inner peripheral surface of the cylindrical portion 31. The fragile portion 25 allows the operation element 41 to slide in the cylindrical portion 31 and the operation element 41 to approach the bottom portion 28. In this way, the fragile portion 25 sinks the operation knob 15 into the hole 14, that is, the front surface 2 a of the front panel 18 a so that the protruding amount of the operation knob 15 from the front surface 2 a of the case 2 is equal to or less than the predetermined value described above. It is allowed to be displaced in the direction to do. As described above, the fragile portion 25 allows the operation knob 15 to be submerged in the hole 14, that is, the front surface 2 a of the front panel 18 a by the protrusion 42 being broken from the inner peripheral surface of the cylindrical portion 31.

前述した支持構造１２は、基板ホルダ３２のホルダ本体３５にスイッチ装置３４を実装した印刷配線板３３が取り付けられて、基板ホルダ３２のヒンジ軸３６がヒンジ支持部２０の孔２１内に通され、係止部２２，３７の係止爪２７，３９を互いに係止されて、組み立てられる。そして、操作ノブ１５が、スイッチ装置３４の操作子４１に取り付けられる。すると、印刷配線板３３及び基板ホルダ３２のホルダ本体３５の表面がフロントパネル１８ａの前面２ａと平行になるとともに、前記一端部３５ａが前記他端部３５ｂよりも前記押圧される力Ｆの前方側に配置されて、印刷配線板３３即ち基板ホルダ３２が、鉛直方向に対して傾いて配置されている。   In the support structure 12 described above, the printed wiring board 33 on which the switch device 34 is mounted is attached to the holder main body 35 of the substrate holder 32, and the hinge shaft 36 of the substrate holder 32 is passed through the hole 21 of the hinge support portion 20. The locking claws 27 and 39 of the locking portions 22 and 37 are locked together and assembled. The operation knob 15 is attached to the operation element 41 of the switch device 34. Then, the front surfaces of the printed wiring board 33 and the holder main body 35 of the substrate holder 32 are parallel to the front surface 2a of the front panel 18a, and the one end 35a is more forward than the other end 35b. The printed wiring board 33, that is, the substrate holder 32 is arranged to be inclined with respect to the vertical direction.

支持構造１２は、操作ノブ１５が押圧されると、この押圧されたことをスイッチ装置３４が検出して、ＡＶ機器１全体の電源をオン・オフし、操作ノブ１５が軸芯回りに回転されると、この回転されたことをスイッチ装置３４が検出して、再生中又は受信中のプログラムの音量を調整するために用いられる。   In the support structure 12, when the operation knob 15 is pressed, the switch device 34 detects that the operation knob 15 is pressed, turns on / off the power supply of the entire AV apparatus 1, and the operation knob 15 is rotated around the axis. Then, the switch device 34 detects this rotation and is used to adjust the volume of the program being reproduced or received.

そして、支持構造１２は、操作ノブ１５が自動車の前後方向（水平方向）に沿って、当該操作ノブ１５をフロントパネル１８ａの前面２ａに向かって押圧されると、図６に示すように、底部２８の端面としての外表面２８ａが鉛直方向と平行になるように、操作ノブ１５が回転する。   When the operation knob 15 is pressed toward the front surface 2a of the front panel 18a along the front-rear direction (horizontal direction) of the automobile, the support structure 12 has a bottom portion as shown in FIG. The operation knob 15 is rotated so that the outer surface 28a as an end face of 28 is parallel to the vertical direction.

そして、前述した押圧される力Ｆが、前述した所定の力よりも弱い第２の所定の力を超えていると、係止部２２，３７の係止爪２７，３９同士の係止が解除されて、ヒンジ軸３６即ち一端部３５ａを中心として、操作ノブ１５が孔１４内即ち前面２ａに没する方向に基板ホルダ３２即ち支持部２３が回転する。すると、図７に示すように、ストッパ部材２４に基板ホルダ３２が接触して、スイッチ装置３４の操作子４１が自動車の前後方向（水平方向）と平行になるとともに、印刷配線板３３即ち基板ホルダ３２と操作ノブ１５の端面としての外表面２８ａが鉛直方向と平行になる。   When the above-described pressing force F exceeds the second predetermined force that is weaker than the above-described predetermined force, the locking claws 27 and 39 of the locking portions 22 and 37 are unlocked. Then, the substrate holder 32, that is, the support portion 23 rotates around the hinge shaft 36, that is, the one end portion 35 a in the direction in which the operation knob 15 is immersed in the hole 14, that is, the front surface 2 a. Then, as shown in FIG. 7, the substrate holder 32 comes into contact with the stopper member 24 so that the operation element 41 of the switch device 34 is parallel to the longitudinal direction (horizontal direction) of the automobile, and the printed wiring board 33, that is, the substrate holder. 32 and an outer surface 28a as an end face of the operation knob 15 are parallel to the vertical direction.

その後、前述した押圧される力Ｆが、前述した所定の力を超えると、図８に示すように、脆弱部２５の突部４２が操作ノブ１５の筒部３１の内周面から破断する。すると、操作子４１が筒部３１内を摺動して、操作ノブ１５が孔１４内即ち前面２ａに没する方向に移動して、図８に示すように、操作子４１と破断した突部４２と底部２８とが密に接触する。すると、勿論、操作ノブ１５の前面２ａからの突出量Ｔ（図８に示す）が、前述した所定の値を下回る。   Thereafter, when the pressing force F described above exceeds the predetermined force described above, the protrusion 42 of the fragile portion 25 is broken from the inner peripheral surface of the cylindrical portion 31 of the operation knob 15 as shown in FIG. Then, the operating element 41 slides in the cylindrical portion 31, and the operating knob 15 moves in the direction of sunk in the hole 14, that is, in the front surface 2a. As shown in FIG. 42 and the bottom 28 are in intimate contact. Then, of course, the protruding amount T (shown in FIG. 8) of the operation knob 15 from the front surface 2a is less than the predetermined value described above.

本実施例によれば、操作ノブ１５を支持したスイッチ装置３４を一端部３５ａがフロントパネル１８ａに取り付けられた基板ホルダ３２に設置し、スイッチ装置３４と操作ノブ１５との間に脆弱部２５を設けているとともに、基板ホルダ３２の他端部３５ｂを係止部２２によってフロントパネル１８ａに取り付けている。そして、操作ノブ１５が自動車の前後方向（水平方向）に沿ってフロントパネル１８ａの前面２ａに向かって脆弱部２５が破断する所定の力よりも弱い第２の所定の力を超えた力で押圧されると、係止部２２の係止が解除されて、ストッパ部材２４によって操作ノブ１５の底部２８の外表面２８ａが鉛直方向と平行な状態に基板ホルダ３２を位置付けられる。   According to the present embodiment, the switch device 34 supporting the operation knob 15 is installed on the substrate holder 32 having one end 35 a attached to the front panel 18 a, and the fragile portion 25 is provided between the switch device 34 and the operation knob 15. While being provided, the other end 35 b of the substrate holder 32 is attached to the front panel 18 a by the locking portion 22. The operation knob 15 is pressed with a force exceeding a second predetermined force that is weaker than a predetermined force that breaks the fragile portion 25 toward the front surface 2a of the front panel 18a along the front-rear direction (horizontal direction) of the automobile. Then, the locking of the locking portion 22 is released, and the substrate holder 32 is positioned by the stopper member 24 so that the outer surface 28a of the bottom portion 28 of the operation knob 15 is parallel to the vertical direction.

こうすることで、脆弱部２５が破断する前に、操作ノブ１５の外表面２８ａが鉛直方向と平行な状態に位置付けられて、当該脆弱部２５が破断する際には、操作ノブ１５がスイッチ装置３４に対して傾くことがない。よって、脆弱部２５が破断する際には、外表面２８ａが鉛直方向と平行な状態の操作ノブ１５に、水平方向に沿ってフロントパネル１８ａの前面２ａに向かって押圧する力が確実に作用することになる。したがって、脆弱部２５が、予め定められた所定の力が操作ノブ１５に作用すると確実に破断することになり、操作ノブ１５がケース２から突出量Ｔが予め定められた値以下となるまで確実にフロントパネル１８ａに対して没することになる。   By doing so, before the fragile portion 25 breaks, the outer surface 28a of the operation knob 15 is positioned in a state parallel to the vertical direction, and when the fragile portion 25 breaks, the operation knob 15 is switched to the switch device. 34 does not tilt. Therefore, when the fragile portion 25 breaks, the force that presses the operation knob 15 with the outer surface 28a parallel to the vertical direction toward the front surface 2a of the front panel 18a along the horizontal direction surely acts. It will be. Therefore, the fragile portion 25 is surely broken when a predetermined predetermined force acts on the operation knob 15, and the operation knob 15 is surely secured until the projection amount T from the case 2 becomes a predetermined value or less. It will be sunk with respect to the front panel 18a.

基板ホルダ３２の一端部３５ａが他端部３５ｂよりも前述した押圧される力Ｆの前方側に配置されているので、係止部２２の係止が解除されると、支持部２３が、一端部３５ａを中心として他端部３５ｂが一端部３５ａと鉛直方向に並ぶ位置に向かって回転することになる。このため、脆弱部２５が破断する際に、操作ノブ１５がスイッチ装置３４に対して傾くことなく、外表面２８ａが鉛直方向と平行な操作ノブ１５に自動車の前後方向（水平方向）に沿ってフロントパネル１８ａの前面２ａに向かって押圧する力Ｆがより確実に作用することになる。   Since the one end portion 35a of the substrate holder 32 is disposed on the front side of the pressing force F described above than the other end portion 35b, when the locking of the locking portion 22 is released, the support portion 23 is The other end 35b rotates around the portion 35a toward a position aligned with the one end 35a in the vertical direction. For this reason, when the fragile portion 25 breaks, the operation knob 15 does not tilt with respect to the switch device 34, and the outer surface 28a extends along the front-rear direction (horizontal direction) of the vehicle to the operation knob 15 parallel to the vertical direction. The force F pressed toward the front surface 2a of the front panel 18a acts more reliably.

基板ホルダ３２をその一端部３５ａを中心として回転自在に支持するヒンジ軸３６を設けているので、係止部２２の基板ホルダ３２の他端部３５ｂの係止が解除されると、当該基板ホルダ３２即ち支持部２３がその一端部３５ａを中心として確実に回転する。このため、脆弱部２５が破断する際に、操作ノブ１５がスイッチ装置３４に対して傾くことなく、外表面２８ａが鉛直方向と平行な操作ノブ１５に自動車の前後方向（水平方向）に沿ってフロントパネル１８ａの前面２ａに向かって押圧する力Ｆがより一層確実に作用することになる。   Since the hinge shaft 36 that supports the substrate holder 32 so as to be rotatable about the one end portion 35a is provided, when the other end portion 35b of the substrate holder 32 of the engaging portion 22 is released, the substrate holder 32, that is, the support portion 23 is reliably rotated around the one end portion 35a. For this reason, when the fragile portion 25 breaks, the operation knob 15 does not tilt with respect to the switch device 34, and the outer surface 28a extends along the front-rear direction (horizontal direction) of the vehicle to the operation knob 15 parallel to the vertical direction. The force F that presses toward the front surface 2a of the front panel 18a acts more reliably.

さらに、ＡＶ機器１は、前述した操作ノブの支持構造１２を備えているので、予め定められた所定の力が操作ノブ１５に作用すると、脆弱部２５が確実に破断することになり、操作ノブ１５がフロントパネル１８ａから突出量Ｔが予め定められた値以下となるまで確実にフロントパネル１８ａに対して没することになる。   Further, since the AV apparatus 1 includes the operation knob support structure 12 described above, when a predetermined force acts on the operation knob 15, the fragile portion 25 is surely broken, and the operation knob 15 is surely submerged with respect to the front panel 18a until the projection amount T becomes equal to or less than a predetermined value from the front panel 18a.

前述した実施例では、ストッパ部材２４をケース２の内部壁１７から立設させている。しかしながら、本発明では、ストッパ部材２４を基板ホルダ３２即ち支部部材２３から立設させても良い。要するに、本発明では、係止部２２，３７の係止爪２７，３９同士の係止が解除された際に、ストッパ部材２４がケース２と基板ホルダ３２の一方に接触して、基板ホルダ３２及び操作ノブ１５の外表面が鉛直方向と平行になるように、当該ストッパ部材２４をケース２と基板ホルダ３２の他方に設ければ良い。   In the embodiment described above, the stopper member 24 is erected from the inner wall 17 of the case 2. However, in the present invention, the stopper member 24 may be erected from the substrate holder 32, that is, the support member 23.

The stopper member 24 may be provided on the other of the case 2 and the substrate holder 32 so that the outer surface of the operation knob 15 is parallel to the vertical direction.

さらに、本発明では、ヒンジ部としてのヒンジ軸３６を設けずに、ケース２のヒンジ支持部２０と基板ホルダ３２とを一体に成形し、これらの間にこれらよりも薄肉に設けられたセルフヒンジを前述したヒンジ部として設けても良い。また、本発明では、脆弱部２５を、操作子４１即ちスイッチ装置３４に一体に設けても良く、操作子４１即ちスイッチ装置３４と操作ノブ１５との双方と別体に設けても良い。要するに、本発明では、脆弱部２５を、操作ノブ１５とスイッチ３４の互いに接触する部分の間に設ければ良い。   Further, in the present invention, the hinge support portion 20 and the substrate holder 32 of the case 2 are integrally formed without providing the hinge shaft 36 as the hinge portion, and the self-hinge provided thinner than these between them. May be provided as the hinge portion described above. In the present invention, the fragile portion 25 may be provided integrally with the operation element 41, that is, the switch device 34, or may be provided separately from both the operation element 41, that is, the switch device 34 and the operation knob 15. In short, in the present invention, the fragile portion 25 may be provided between the portions of the operation knob 15 and the switch 34 that are in contact with each other.

前述した実施例では、電子機器として自動車に取り付けられるＡＶ機器１を示している。しかしながら、本発明では、ＡＶ機器１に限らず、種々の電子機器に適用しても良い。   In the above-described embodiment, the AV device 1 attached to a car as an electronic device is shown.

付記によれば、操作ノブ１５を支持したスイッチ装置３４を一端部３５ａがフロントパネル１８ａに取り付けられた基板ホルダ３２に設置し、スイッチ装置３４と操作ノブ１５との間に脆弱部２５を設けているとともに、基板ホルダ３２の他端部３５ｂを係止部２２によってフロントパネル１８ａに取り付けている。そして、操作ノブ１５が自動車の前後方向（水平方向）に沿ってフロントパネル１８ａの前面２ａに向かって脆弱部２５が破断する所定の力よりも弱い第２の所定の力を超えた力で押圧されると、係止部２２の係止が解除されて、ストッパ部材２４によって操作ノブ１５の底部２８の外表面２８ａが鉛直方向と平行な状態に基板ホルダ３２を位置付けられる。   According to the remarks, the switch device 34 supporting the operation knob 15 is installed on the substrate holder 32 whose one end 35 a is attached to the front panel 18 a, and the fragile portion 25 is provided between the switch device 34 and the operation knob 15. In addition, the other end portion 35 b of the substrate holder 32 is attached to the front panel 18 a by the locking portion 22. The operation knob 15 is pressed with a force exceeding a second predetermined force that is weaker than a predetermined force that breaks the fragile portion 25 toward the front surface 2a of the front panel 18a along the front-rear direction (horizontal direction) of the automobile. Then, the locking of the locking portion 22 is released, and the substrate holder 32 is positioned by the stopper member 24 so that the outer surface 28a of the bottom portion 28 of the operation knob 15 is parallel to the vertical direction.

こうすることで、脆弱部２５が破断する前に、操作ノブ１５の外表面２８ａが鉛直方向と平行な状態に位置付けられて、当該脆弱部２５が破断する際には、操作ノブ１５がスイッチ装置３４に対して傾くことがない。よって、脆弱部２５が破断する際には、外表面２８ａが鉛直方向と平行な操作ノブ１５に水平方向に沿ってフロントパネル１８ａの前面２ａに向かって押圧する力が確実に作用することになる。したがって、脆弱部２５が、予め定められた所定の力が操作ノブ１５に作用すると確実に破断することになり、操作ノブ１５がケース２から突出量Ｔが予め定められた値以下となるまで確実にフロントパネル１８ａに対して没することになる。   By doing so, before the fragile portion 25 breaks, the outer surface 28a of the operation knob 15 is positioned in a state parallel to the vertical direction, and when the fragile portion 25 breaks, the operation knob 15 is switched to the switch device. 34 does not tilt. Therefore, when the fragile portion 25 breaks, the force that the outer surface 28a presses the operation knob 15 parallel to the vertical direction along the horizontal direction toward the front surface 2a of the front panel 18a surely acts. . Therefore, the fragile portion 25 is surely broken when a predetermined predetermined force acts on the operation knob 15, and the operation knob 15 is surely secured until the projection amount T from the case 2 becomes a predetermined value or less. It will be sunk with respect to the front panel 18a.
