Abstract

<P>PROBLEM TO BE SOLVED: To provide a low-cost detection mechanism for a rotating operation member mounted on an operation panel while capable of detecting both a rotating direction and a rotating amount. <P>SOLUTION: The detection mechanism includes an elastic sheet 30 which is integrally equipped with a rocking part 40 having a base part 32, first and second movable contact points 45a, 45b, and a coupling part 34 coupling the rocking part 40 in free rocking with the base part 32. When the rocking part 40 slants to a first (a second) direction by abutting of an abutting part 18 to the rocking part 40 in a state in which a rotation part 16 rotates to the first (second) rotating direction, the coupling part 34 permits the first (second) movable contact point 45a (45b) to contact the first (second) contact point 22a (22b) by elastic deformation. When the abutting part 18 separates from the rocking part 40, the first (second) movable contact point 45a (45b) separates from the first (second) contact point 22a (22b) by making the slanted rocking part 40 stand up by elastic return force. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、車両等の操作パネルの裏側に配置され、当該操作パネルに配設された回転操作部材の回転方向及び回転量を検知する検知機構に関する。   The present invention relates to a detection mechanism that is disposed on the back side of an operation panel of a vehicle or the like and detects a rotation direction and a rotation amount of a rotation operation member disposed on the operation panel.

従来、回転操作部材が配設された操作パネルの裏側に配置され、前記回転操作部材の回転方向及び回転量を検知する検知機構として、ロータリーエンコーダが知られている。このロータリーエンコーダは、軸等の回転方向や回転量を検知することはできるが高価である。   2. Description of the Related Art Conventionally, a rotary encoder is known as a detection mechanism that is disposed on the back side of an operation panel provided with a rotation operation member and detects the rotation direction and the rotation amount of the rotation operation member. This rotary encoder can detect the rotation direction and rotation amount of a shaft or the like, but is expensive.

そこで、コストを削減するために、回転操作部材の回転方向及び回転量の検知機構として、オン・オフの切り換えといった簡素な構成を組み合わせることで回転操作部材の回転方向及び回転量を検知可能とした二方向スイッチ素子が用いられた。   Therefore, in order to reduce the cost, the rotation direction and rotation amount of the rotation operation member can be detected by combining a simple configuration such as on / off switching as the rotation direction and rotation amount detection mechanism of the rotation operation member. A bi-directional switch element was used.

この二方向スイッチ素子として、例えば、特許文献１に示されるものが知られている。具体的に、この二方向スイッチ素子は、図１５及び図１６に示されるように、ダイヤルスイッチ１００のノブ（回転操作部材）１００ａの回転に基づいて回転軸１２１ａを中心にして先端側が揺動する揺動片１２１と、２つの接点１２４ａ，１２４ｂを有し、これら２つの接点１２４ａ，１２４ｂ間が導通可能に接続されるスイッチバネ１２４と、このスイッチバネ１２４に揺動片１２１の揺動を伝達する伝達部１２２と、揺動片１２１の先端側を突出させた状態で当該揺動片１２１、伝達部１２２及びスイッチバネ１２４を収容し、揺動片１２１の揺動がスイッチバネ１２４に伝達されることで当該スイッチバネ１２４の各接点１２４ａ，１２４ｂが摺接する摺接面１２３ａを有する本体ケース１２３と、を備える。本体ケース１２３の摺接面１２３ａには、スイッチバネ１２４の接点１２４ａ，１２４ｂの摺動方向に間隔をおいて３つの接点１３１，１３２，１３３が設けられ、各接点１３１，１３２，１３３には本体ケース１２３の外部に延びる端子１３１ａ，１３２ａ，１３３ａがそれぞれ接続されている。   As this two-way switch element, for example, one shown in Patent Document 1 is known. Specifically, as shown in FIG. 15 and FIG. 16, the two-way switch element swings on the distal end side about the rotation shaft 121 a based on the rotation of the knob (rotation operation member) 100 a of the dial switch 100. A swing spring 121 and two contact points 124 a and 124 b, a switch spring 124 connected between the two contact points 124 a and 124 b so as to be conductive, and the swing of the swing piece 121 are transmitted to the switch spring 124. The oscillating piece 121, the transmitting part 122, and the switch spring 124 are accommodated in a state where the tip of the oscillating piece 121 and the oscillating piece 121 project, and the oscillation of the oscillating piece 121 is transmitted to the switch spring 124. And a main body case 123 having a slidable contact surface 123a with which the contact points 124a and 124b of the switch spring 124 are slidably contacted. Three contact points 131, 132, 133 are provided on the sliding contact surface 123 a of the main body case 123 at intervals in the sliding direction of the contacts 124 a, 124 b of the switch spring 124, and each of the contacts 131, 132, 133 has a main body. Terminals 131a, 132a, 133a extending to the outside of the case 123 are connected to each other.

この二方向スイッチ素子１２０は、揺動片１２１の先端側に対して、当該揺動片１２１の揺動方向の一方側から（図１６において先端部が左から右に向って）力が加わると、当該揺動片１２１の先端側が同方向に倒れる。この揺動が伝達部１２２によりスイッチバネ１２４に伝達されると、スイッチバネ１２４が弾性変形しつつ本体ケース１２３内で移動（図１６のＡ方向に移動）し、これに伴って接点１２４ａ及び接点１２４ｂが摺接面１２３ａ上を摺動して摺接面１２３ａの接点１３１及び接点１３２にそれぞれ接触する。そうすると、スイッチバネ１２４を介して摺接面１２３ａの接点１３１及び接点１３２に接続される端子１３１ａ，１３２ａ間が導通状態（オン）となる。そして、揺動片１２１の先端側に加わっていた力が無くなると、弾発力によってスイッチバネ１２４が弾性復帰して初期位置に戻り、摺接面１２３ａの接点１３１及び接点１３２からスイッチバネの接点１２４ａ及び接点１２４ｂがそれぞれ離れ、端子１３１ａ，１３２ａ間が絶縁状態（オフ）に戻る。   When the bi-directional switch element 120 is applied with a force from one side in the swing direction of the swing piece 121 (the tip end portion is directed from the left to the right in FIG. 16) on the tip end side of the swing piece 121. The tip side of the swing piece 121 falls in the same direction. When this swing is transmitted to the switch spring 124 by the transmission portion 122, the switch spring 124 moves in the main body case 123 while being elastically deformed (moved in the direction A in FIG. 16), and accordingly, the contact 124a and the contact 124b slides on the sliding contact surface 123a and contacts the contact 131 and the contact 132 of the sliding contact surface 123a, respectively. If it does so, between the terminals 131a and 132a connected to the contact 131 of the sliding contact surface 123a and the contact 132 via the switch spring 124 will be in a conduction | electrical_connection state (ON). When the force applied to the distal end side of the swing piece 121 disappears, the switch spring 124 is elastically restored by the elastic force and returns to the initial position, and the contact of the switch spring from the contact 131 and the contact 132 of the sliding contact surface 123a. 124a and the contact 124b are separated from each other, and the terminals 131a and 132a return to the insulated state (off).

揺動片１２１が反対側に（図１６において先端部が右から左に向かって）押し倒されると、スイッチバネ１２４が弾性変形しつつ本体ケース１２３内で移動（図１６のＢ方向に移動）して接点１２４ａ及び接点１２４ｂが摺接面１２３ａの接点１３２及び１３３にそれぞれ接触して端子１３２ａ，１３３ａ間が導通状態（オン）となる。そして、揺動片１２１に加わっていた力が無くなると、スイッチバネ１２４が弾性復帰して初期位置に戻り、端子１３２ａ，１３３ａ間が絶縁状態（オフ）に戻る。   When the swing piece 121 is pushed down to the opposite side (in FIG. 16, the tip is from right to left), the switch spring 124 is moved in the body case 123 while being elastically deformed (moved in the direction B in FIG. 16). Then, the contact 124a and the contact 124b come into contact with the contacts 132 and 133 on the sliding contact surface 123a, respectively, and the terminals 132a and 133a are in a conductive state (ON). When the force applied to the swing piece 121 is lost, the switch spring 124 is elastically restored to return to the initial position, and the terminals 132a and 133a return to the insulated state (off).

このように構成される二方向スイッチ素子１２０は、図１５に示されるように、回転操作されるノブ１００ａの近傍に配置される。ノブ１００ａの外周面からは周方向に所定間隔をおいて複数の当接部１０１が突出している。このノブ１００ａが回転操作されると、各当接部１０１が次々に二方向スイッチ素子１２０の揺動片１２１の先端側に当接して揺動片１２１を押し倒す（揺動させる）。このときに各端子間の導通回数が検知され、これに基づき回転方向及び回転量が検知される。   The two-way switch element 120 configured as described above is disposed in the vicinity of the knob 100a to be rotated as shown in FIG. A plurality of contact portions 101 protrude from the outer peripheral surface of the knob 100a at a predetermined interval in the circumferential direction. When the knob 100a is operated to rotate, the contact portions 101 successively come into contact with the distal end side of the swing piece 121 of the two-way switch element 120 to push down (swing) the swing piece 121. At this time, the number of conductions between the terminals is detected, and based on this, the rotation direction and the rotation amount are detected.

しかし、前記の二方向スイッチ素子１２０は、前記のロータリーエンコーダよりは安価であるが、構成が複雑であるためオン・オフを切り換えるだけの通常のスイッチ素子に比べて高価である。そのため、二方向スイッチ素子１２０を用いても操作パネルに配設された回転操作部材の回転方向及び回転量を検知する検知機構としてコストの削減を十分に図ることができなかった。   However, the two-way switch element 120 is less expensive than the rotary encoder, but is more expensive than a normal switch element that only switches on and off because of its complicated configuration. Therefore, even if the two-way switch element 120 is used, the cost cannot be sufficiently reduced as a detection mechanism for detecting the rotation direction and the rotation amount of the rotary operation member disposed on the operation panel.

そこで、上記問題点に鑑み、操作パネルに配設された回転操作部材の回転方向及び回転量の双方を検知可能でありながらコストを抑えた検知機構を提供することを課題とする。   In view of the above problems, an object of the present invention is to provide a detection mechanism that can detect both the rotation direction and the rotation amount of the rotary operation member disposed on the operation panel while reducing the cost.

そこで、上記課題を解消すべく、本発明者らは、回路基板上に配設される弾性シートに着目した。この弾性シートは、遮光、防水、あるいは押圧スイッチの構築といった目的で操作パネルと回路基板との間に介設されるものであり、この弾性シートを回転検知機構に利用することで、本発明の目的を達成することが可能となることを発見した。   Therefore, in order to solve the above problems, the present inventors have focused on an elastic sheet disposed on a circuit board. This elastic sheet is interposed between the operation panel and the circuit board for the purpose of light shielding, waterproofing, or construction of a push switch, and by utilizing this elastic sheet for the rotation detection mechanism, I found that it was possible to achieve the objective.

具体的に、本発明は、回転操作部材が配設された操作パネルの裏側に配置され、前記回転操作部材の回転方向及び回転量を検知する検知機構であって、前記回転操作部材の回転と一体に回転し、その回転方向に沿って間隔をおいて並ぶ複数の当接部を有する回転部と、前記操作パネルの裏側に配置されて当該操作パネルと対向する表面に第１基板側接点及び第２基板側接点を有する回路基板と、前記回路基板の表面上に配設される弾性シートと、を備える。そして、前記弾性シートは、前記第１基板側接点及び前記第２基板側接点を含む領域を残してその外側の領域で前記回路基板の表面上に敷設されるベース部と、前記残された領域内から前記回路基板と反対の側に延び、前記第１基板側接点及び前記第２基板側接点と対応する位置に第１可動接点及び第２可動接点をそれぞれ有する揺動部と、前記揺動部を揺動可能に前記ベース部に連結する連結部と、を一体に有し、前記連結部は、前記回転部が第１の回転方向へ回転した状態で前記当接部が前記揺動部に当接することでこの揺動部がその先端を所定の第１の方向に向けて傾き前記第１可動接点が前記第１基板側接点に接触するのを弾性変形により許容すると共に、前記揺動部に当接した当接部が当該揺動部から離間することで前記第１の方向に傾いた揺動部を弾性復帰力により起立させて前記第１基板側接点から前記第１可動接点を離間させる一方、前記回転部が前記第１の回転方向と反対の第２の回転方向へ回転した状態で前記当接部が前記揺動部に当接することでこの揺動部がその先端を前記所定の第１の方向と反対の側の第２の方向に向けて傾き前記第２可動接点が前記第２基板側接点に接触するのを弾性変形により許容すると共に、前記揺動部に当接した当接部が当該揺動部から離間することで前記第２の方向に傾いた揺動部を弾性復帰力により起立させて前記第２基板側接点から前記第２可動接点を離間させ、前記複数の当接部は、前記回転部が前記第１の回転方向に回転するのに伴い、一つの当接部が前記揺動部に当接することにより当該揺動部を前記第１の方向に傾けたあと次の当接部が当該揺動部に当接するまでの間に当該揺動部が起立して前記第１可動接点と前記第１基板側接点とが離間した状態となり、前記回転部が前記第２の回転方向に回転するのに伴い、一つの当接部が前記揺動部に当接することにより当該揺動部を前記第２の方向に傾けたあと次の当接部が当該揺動部に当接するまでの間に当該揺動部が起立して前記第２可動接点と前記第２基板側接点とが離間した状態となるような間隔で並んでいることを特徴とする。   Specifically, the present invention is a detection mechanism that is disposed on the back side of the operation panel provided with the rotation operation member and detects the rotation direction and the rotation amount of the rotation operation member. A rotating part having a plurality of abutting parts that rotate integrally and are arranged at intervals along the rotation direction; and a first substrate side contact and a surface disposed on the back side of the operation panel and facing the operation panel; A circuit board having a second substrate side contact; and an elastic sheet disposed on the surface of the circuit board. The elastic sheet has a base portion laid on the surface of the circuit board in a region outside the region including the first substrate side contact and the second substrate side contact, and the remaining region. An oscillating portion extending from the inside to the opposite side of the circuit board and having a first movable contact and a second movable contact at positions corresponding to the first substrate side contact and the second substrate side contact, and the oscillation And a connecting portion that is connected to the base portion so as to be swingable. The connecting portion is configured such that the contact portion is the swinging portion while the rotating portion is rotated in the first rotation direction. The swinging portion tilts with its tip in a predetermined first direction by allowing the first movable contact to contact the first substrate side contact by elastic deformation, and the swinging portion When the contact portion that is in contact with the portion is separated from the swinging portion, the first direction The oscillating part tilted to stand up by an elastic restoring force separates the first movable contact from the first substrate side contact, while the rotating part moves in a second rotational direction opposite to the first rotational direction. When the contact portion contacts the swinging portion in a rotated state, the swinging portion tilts its tip toward a second direction opposite to the predetermined first direction. The contact is allowed to come into contact with the second substrate side contact by elastic deformation, and the abutting portion in contact with the oscillating portion is separated from the oscillating portion so that the oscillating member tilts in the second direction. The moving portion is erected by an elastic return force to separate the second movable contact from the second substrate side contact, and the plurality of contact portions are provided as the rotating portion rotates in the first rotation direction. , When one abutting portion abuts on the oscillating portion, the oscillating portion is moved in the first direction. The first swing contact and the first contact on the substrate side are separated from each other until the next contact portion comes into contact with the swing portion, and the rotating portion is As the second rotating direction rotates, one abutting portion abuts on the oscillating portion, whereby the oscillating portion is tilted in the second direction, and the next abutting portion is oscillated. Before the contact with the moving part, the oscillating part stands up and the second movable contact and the second substrate side contact are spaced apart from each other.

かかる構成によれば、回転操作部材の回転操作によって当接部が揺動部に次々に当接して揺動部が揺動することにより、回転操作部材の回転方向及び回転量の両方をそれぞれ検知できる。即ち、揺動部が各当接部の当接によって傾いたときに、いずれの接点同士が接触したかで回転操作部材の回転方向を検知し、その接触回数によって回転量を検知することができる。   According to such a configuration, both the rotation direction and the rotation amount of the rotation operation member are detected by the contact portion sequentially contacting the swinging portion and the swinging portion swinging by the rotation operation of the rotation operation member. it can. That is, when the swinging portion is tilted by the contact of each contact portion, the rotation direction of the rotation operation member can be detected depending on which contact point is in contact with each other, and the rotation amount can be detected by the number of times of contact. .

しかも、操作パネルの裏側に回路基板が配置されたときに、この回路基板の防水や遮光のために当該回路基板と操作パネルとの間に配設される弾性シートの一部を利用して前記回転操作部材の回転方向及び回転量を検知する手段を構成させることでコストの削減を図ることができる。   In addition, when the circuit board is disposed on the back side of the operation panel, the circuit board is waterproofed or shielded by using a part of the elastic sheet disposed between the circuit board and the operation panel. Costs can be reduced by configuring means for detecting the direction and amount of rotation of the rotary operation member.

本発明に係る操作パネルに配設された回転操作部材の回転方向及び回転量を検知する検知機構においては、前記揺動部は、当該揺動部の先端側に設けられ、第１の回転方向へ前記回転部が回転したときに前記各当接部が当接可能な方向を向いた第１当接面と、当該揺動部の先端側に設けられ、前記第１の回転方向と反対の第２の回転方向へ前記回転部が回転したときに前記各当接部が当接可能な方向を向いた第２当接面とを有し、前記第１当接面は、前記回転部が第１の回転方向へ回転している状態で前記当接部が当該第１当接面に当接したあと当該第１当接面上を当該第１当接面に沿って通過することにより、前記揺動部がその先端を第１の方向に向けて傾き前記第１可動接点が前記第１基板側接点に接触する形状を有し、前記第２当接面は、前記回転部が第２の回転方向へ回転している状態で前記当接部が当該第２当接面に当接したあと当該第２当接面上を当該第２当接面に沿って通過することにより、前記揺動部がその先端を前記第１の方向と反対の側の第２の方向に向けて傾き前記第２可動接点が前記第２基板側接点に接触する形状を有すること、が好ましい。   In the detection mechanism for detecting the rotation direction and the rotation amount of the rotary operation member disposed on the operation panel according to the present invention, the swinging portion is provided on the distal end side of the swinging portion, and the first rotation direction A first abutting surface facing in a direction in which the abutting portions can abut when the rotating portion is rotated, and a tip side of the swinging portion, opposite to the first rotating direction.

Are preferred.

このように回転部が回転した状態でその当接部が揺動部に当接したときの当該揺動部の傾く方向や傾き度合い等を揺動部の先端側に設けられた二つの面（第１当接面及び第２当接面）によって調整する構成とすることで、当該検知機構の構成の簡素化を図ることができる。   The two surfaces provided on the tip side of the swinging portion indicate the tilting direction and the tilting degree of the swinging portion when the contacting portion comes into contact with the swinging portion with the rotating portion rotating in this manner ( By adopting a configuration that is adjusted by the first contact surface and the second contact surface, the configuration of the detection mechanism can be simplified.

前記揺動部は、揺動部本体と、前記揺動部本体を揺動可能に前記回路基板に接続して前記揺動の支点となる接続部とを有すること、が好ましい。   It is preferable that the oscillating portion includes an oscillating portion main body and a connecting portion that is connected to the circuit board so that the oscillating portion main body can oscillate and serves as a fulcrum of the oscillating.

かかる構成によれば、揺動部が傾いたときに第１可動接点又は第２可動接点が回路基板上の対応する接点とずれることなく確実に接触する。即ち、揺動部が当接部により押し倒されたときに接続部を支点に揺動部が傾くことで、揺動部と回路基板との回路基板に沿った方向の相対位置がずれるのを防止することができる。   According to such a configuration, when the swinging portion is tilted, the first movable contact or the second movable contact is reliably in contact with the corresponding contact on the circuit board. That is, when the swinging portion is pushed down by the contact portion, the swinging portion is tilted with the connecting portion as a fulcrum, thereby preventing the relative position of the swinging portion and the circuit board in the direction along the circuit board from being shifted. can do.

この場合、具体的には、例えば、前記回路基板は、前記揺動体の接続部と対応する位置に穴部を有し、前記接続部は、前記揺動部本体の回路基板側の端部から前記回路基板の穴部内に向って延びると共に当該回路基板の穴部の内径に対応する外径を有し、前記揺動方向に撓み変形可能であってもよい。   In this case, specifically, for example, the circuit board has a hole at a position corresponding to the connection portion of the oscillating body, and the connection portion extends from an end of the oscillating portion main body on the circuit board side. The circuit board may extend toward the inside of the hole of the circuit board and have an outer diameter corresponding to the inner diameter of the hole of the circuit board, and bendable and deformable in the swinging direction.

The first contact surface and the second contact surface are arranged to face each other, and the first contact surface and the second contact surface include the first movable contact and the second movable contact, and the swinging portion stands upright. In the state, both contact surfaces are separated from the surface of the circuit board, and when the swinging portion is inclined in the first direction and the first contact surface is in contact with the surface of the circuit board, the second contact surface is The swinging portion is separated from the surface of the circuit board and the swinging portion is tilted in the second direction so that the second contact The first contact surface has a shape that separates from the surface of the circuit board when the surface comes into contact with the surface of the circuit board, and the first movable contact has the first contact surface as a surface of the circuit board. A shape that makes contact between the third substrate side contact and the first substrate side contact by straddling the third substrate side contact and the first substrate side contact, The second movable contact contacts the third substrate side contact and the second substrate side contact when the second contact surface contacts the surface of the circuit board, and the third substrate side contact It is preferable to have a shape for conducting between the second substrate side contact.

このように一方の接触面が回路基板の表面に接触したときに他方の接触面が回路基板の表面から離間し、且つ他方の接触面が回路基板の表面に接触したときに一方の接触面が回路基板の表面から離間する第１接触面及び第２接触面が揺動部に設けられることで、回転操作部材の回転方向及び回転量の誤検知を好適に抑止することができる。即ち、揺動部が第１の方向に傾いて第１接触面が回路基板の表面に接触することで第１基板側接点と第３基板側接点との間が導通状態となったときに第２接触面が回路基板の表面から離間するため第２基板側接点と第３基板側接点との間が確実に非導通状態となる一方、揺動部が第２の方向に傾いて第２接触面が回路基板の表面に接触して第２基板側接点と第３基板側接点との間が導通状態のときに第１接触面が回路基板の表面から離間するため第１基板側接点と第３基板側接点との間が確実に非導通状態となる。   Thus, when one contact surface contacts the surface of the circuit board, the other contact surface separates from the surface of the circuit board, and when the other contact surface contacts the surface of the circuit board, Since the first contact surface and the second contact surface that are separated from the surface of the circuit board are provided in the swinging portion, erroneous detection of the rotation direction and the rotation amount of the rotation operation member can be suitably suppressed. That is, when the swinging portion is tilted in the first direction and the first contact surface comes into contact with the surface of the circuit board, the first board side contact and the third board side contact become conductive. Since the second contact surface is separated from the surface of the circuit board, the contact between the second substrate side contact and the third substrate side contact is surely made non-conductive, while the swinging portion is inclined in the second direction and the second contact is made. Since the first contact surface is separated from the surface of the circuit board when the surface contacts the surface of the circuit board and the second board side contact and the third board side contact are conductive, the first board side contact and the first board side contact The non-conducting state is surely established between the three substrate side contacts.

このような第１接触面と第２接触面とが揺動部に設けられる場合、前記第１可動接点と第２可動接点とが一体に形成されても、揺動部の傾く方向に応じて第１基板側接点と第３基板側接点との間、又は第２基板側接点と第３基板側接点との間のいずれか一方の接点間しか導通状態とならない。これにより、二つの可動接点を一体に形成しても回転方向や回転量の誤検知を防止することができる。また、二つの可動接点を一体に形成することにより部品点数の削減や構成の簡素化を図ることも可能となる。   When such a first contact surface and a second contact surface are provided in the swinging portion, even if the first movable contact and the second movable contact are formed integrally, depending on the direction in which the swinging portion tilts. Only one of the contacts between the first substrate side contact and the third substrate side contact or between the second substrate side contact and the third substrate side contact is brought into conduction. Thereby, it is possible to prevent erroneous detection of the rotation direction and the rotation amount even if the two movable contacts are integrally formed. In addition, by forming the two movable contacts integrally, it is possible to reduce the number of parts and simplify the configuration.

以上より、本発明によれば、操作パネルに配設された回転操作部材の回転方向及び回転量の双方を検知可能でありながらコストを抑えた検知機構を提供することができる。   As described above, according to the present invention, it is possible to provide a detection mechanism that can detect both the rotation direction and the rotation amount of the rotary operation member disposed on the operation panel while suppressing the cost.

以下、本発明の一実施形態について、図１〜図１０を参照しつつ説明する。   Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

本実施形態に係る操作パネルに配設された回転操作部材の回転方向及び回転量を検知する検知機構（以下、単に「検知機構」とも称する。）１０は、例えば、自動車の車室内に設けられるインストゥルメントパネル等の操作パネルの裏側に配置され、この操作パネルに設けられたダイヤルスイッチ等の回転操作部材の回転方向及び回転量を検知する機構である。以下、具体的に説明する。   A detection mechanism (hereinafter also simply referred to as “detection mechanism”) 10 for detecting the rotation direction and the rotation amount of a rotary operation member disposed on an operation panel according to the present embodiment is provided, for example, in a vehicle interior of an automobile. It is a mechanism that is arranged on the back side of an operation panel such as an instrument panel and detects the rotation direction and the rotation amount of a rotary operation member such as a dial switch provided on the operation panel. This will be specifically described below.

本実施形態の検知機構１０は、前記のようにインストゥルメントパネル（以下、「操作パネル」と称する。）Ｐの裏側に配置される。この操作パネルＰには、図１〜図４に示されるダイヤルスイッチ１２が配設される。このダイヤルスイッチ１２は、例えば、エアコンのオン・オフや設定温度を変更するため等に用いられる。ダイヤルスイッチ１２は、ダイヤルノブ（回転操作部材）１４と回転部１６とを備え、回路基板２０に配設される。これらダイヤルノブ１４及び回転部１６は操作パネルＰと略直交する軸（回転軸）Ｃを回転中心にして回動可能に配設される。   The detection mechanism 10 of the present embodiment is disposed on the back side of the instrument panel (hereinafter referred to as “operation panel”) P as described above. The operation panel P is provided with a dial switch 12 shown in FIGS. The dial switch 12 is used, for example, for turning on / off an air conditioner or changing a set temperature. The dial switch 12 includes a dial knob (rotation operation member) 14 and a rotation unit 16, and is disposed on the circuit board 20. The dial knob 14 and the rotating portion 16 are disposed so as to be rotatable about an axis (rotating axis) C substantially orthogonal to the operation panel P.

ダイヤルノブ１４は、ダイヤルスイッチ１２において運転者等の操作者によって回転操作される略円柱状の部位である。このダイヤルノブ１４は、ダイヤルスイッチ１２が配設された回路基板２０が操作パネルＰの裏側に配置されたときに、先端側の部分が操作パネルＰから車室内に向けて突出する（図２参照）。   The dial knob 14 is a substantially cylindrical portion that is rotated by an operator such as a driver in the dial switch 12. When the circuit board 20 on which the dial switch 12 is disposed is arranged on the back side of the operation panel P, the dial knob 14 protrudes from the operation panel P toward the vehicle interior (see FIG. 2). ).

回転部１６は、回路基板２０が操作パネルＰの裏側に配置されたときにこの操作パネルＰと回路基板２０との間に位置し、ダイヤルノブ１４が回転操作されたときにこのダイヤルノブ１４と一体に回転する部位である。この回転部１６は、回路基板２０と共に検知機構１０の一部を構成し、複数の当接部１８を有する。これら複数の当接部１８は、回転部１６の回転方向に沿って間隔をおいて並んでいる（図５参照）。   The rotating unit 16 is positioned between the operation panel P and the circuit board 20 when the circuit board 20 is disposed on the back side of the operation panel P, and when the dial knob 14 is rotated, It is a part that rotates together. The rotating unit 16 constitutes a part of the detection mechanism 10 together with the circuit board 20 and has a plurality of contact portions 18. The plurality of contact portions 18 are arranged at intervals along the rotation direction of the rotation portion 16 (see FIG. 5).

具体的に、回転部１６は、ダイヤルノブ１４の回路基板２０側に接続され、回路基板２０から所定の間隔をおいた位置で回転軸Ｃを回転中心にして回転する。この回転部１６の回路基板側の端部には、回転方向に沿って複数の当接部１８が所定の間隔で並んでいる。複数の当接部１８は、回転部１６が回転したときに回転軸Ｃを中心とする単一の円形軌道αをそれぞれ通るように回転部１６に配列されている。本実施形態の当接部１８は、回転部１６の回路基板側端部の周縁部から回路基板２０に向けて突出する突出片により構成されている。回転部１６と回路基板２０との間隔は、検知機構１０の揺動部４０（図３（Ａ）参照）における回転軸Ｃ方向の長さ寸法に基づいて設定される。本実施形態の回転部１６と回路基板２０との間隔は、回転部１６が回転するのに伴って各当接部１８が揺動部４０の先端部（詳しくは第１当接面４７ａ又は第２当接面４７ｂ）に当接するような間隔に設定されている。また、回転部１６には、回転軸Ｃを中心にして当該回転部１６を外側から囲む外筒部１９が設けられている。   Specifically, the rotating unit 16 is connected to the circuit board 20 side of the dial knob 14 and rotates around the rotation axis C at a position spaced from the circuit board 20 by a predetermined distance. A plurality of contact portions 18 are arranged at predetermined intervals along the rotation direction at the end of the rotation portion 16 on the circuit board side. The plurality of abutting portions 18 are arranged in the rotating portion 16 so as to pass through a single circular orbit α about the rotation axis C when the rotating portion 16 rotates. The contact portion 18 of the present embodiment is configured by a protruding piece that protrudes toward the circuit board 20 from the peripheral edge portion of the end portion on the circuit board side of the rotating portion 16. The interval between the rotation unit 16 and the circuit board 20 is set based on the length dimension in the rotation axis C direction in the swinging unit 40 (see FIG. 3A) of the detection mechanism 10. In the present embodiment, the interval between the rotating portion 16 and the circuit board 20 is such that each abutting portion 18 moves to the tip end portion of the swinging portion 40 (specifically, the first abutting surface 47a or the first substrate) as the rotating portion 16 rotates. 2 is set so as to be in contact with the contact surface 47b). Further, the rotating portion 16 is provided with an outer cylinder portion 19 that surrounds the rotating portion 16 from the outside with the rotation axis C as the center.

尚、本実施形態の回転部１６は、ダイヤルノブ１４に接続されているが、ダイヤルノブ１４と離れた位置に配設されてもよい。この場合、回転部１６がダイヤルノブ１４の回転と一体に回転できるようにダイヤルノブ１４の回転を伝達する伝達機構等がダイヤルノブ１４と回転部１６との間に設けられる。   In addition, although the rotation part 16 of this embodiment is connected to the dial knob 14, it may be arrange | positioned in the position away from the dial knob 14. FIG. In this case, a transmission mechanism or the like for transmitting the rotation of the dial knob 14 is provided between the dial knob 14 and the rotation unit 16 so that the rotation unit 16 can rotate integrally with the rotation of the dial knob 14.

検知機構１０は、前記の回転部１６及び回路基板２０と、回路基板２０の表面２０ａ上に配設されるラバーシート（弾性シート）３０とを備える。ここで、本実施形態の回路基板２０の表面２０ａとは、当該回路基板２０が操作パネルＰの裏側に当該操作パネルＰと略平行な姿勢で配置されたときにこの操作パネルＰと対向する面のことをいう。   The detection mechanism 10 includes the rotating unit 16 and the circuit board 20, and a rubber sheet (elastic sheet) 30 disposed on the surface 20 a of the circuit board 20. Here, the surface 20a of the circuit board 20 of the present embodiment is a surface that faces the operation panel P when the circuit board 20 is disposed on the back side of the operation panel P in a posture substantially parallel to the operation panel P. I mean.

回路基板２０は、当該回路基板２０の表面２０ａにおけるダイヤルスイッチ１２と近接する位置に基板側接点２２を有する。また、回路基板２０には、揺動部４０を回路基板２０に接続する接続部４６と対応する位置に当該接続部４６が嵌入される接続用穴部２３を有する。具体的に、これら基板側接点２２及び接続用穴部２３は、回路基板２０の表面２０ａを当該表面２０ａと直交する方向から見たときに前記の各当接部１８が通る円形軌道αと重なる特定の位置にそれぞれ設けられる。また、回路基板２０の表面２０ａ上には、種々の電子部品や光源等も実装される。   The circuit board 20 has a board-side contact 22 at a position close to the dial switch 12 on the surface 20 a of the circuit board 20. Further, the circuit board 20 has a connection hole 23 into which the connection part 46 is fitted at a position corresponding to the connection part 46 that connects the swinging part 40 to the circuit board 20. Specifically, the board-side contact 22 and the connection hole 23 overlap with the circular track α through which each contact portion 18 passes when the surface 20a of the circuit board 20 is viewed from a direction orthogonal to the surface 20a. Each is provided at a specific position. Various electronic components, light sources, and the like are also mounted on the surface 20 a of the circuit board 20.

基板側接点２２は、図６にも示されるように、第１接点（第１基板側接点）２２ａ、中央接点（第３基板側接点）２２ｃ、及び第２接点（第２基板側接点）２２ｂを有する。各接点（第１接点２２ａ、中央接点２２ｃ、及び第２接点２２ｂ）は、回路基板２０の表面２０ａにおいて、揺動部４０の揺動方向に沿って、第１接点２２ａ、中央接点２２ｃ、第２接点２２ｂの順に間隔をおいて並んでいる。尚、本実施形態において揺動部４０の揺動方向とは、回路基板２０の表面２０ａに対して直交する方向から当接部１８の円形軌道αを見たときの前記特定の位置における円形軌道αの接線方向（図５の矢印参照）である。   As shown in FIG. 6, the substrate side contact 22 includes a first contact (first substrate side contact) 22a, a center contact (third substrate side contact) 22c, and a second contact (second substrate side contact) 22b. Have Each contact (the first contact 22a, the center contact 22c, and the second contact 22b) is arranged on the surface 20a of the circuit board 20 along the swing direction of the swing portion 40, the first contact 22a, the center contact 22c, the second contact. The two contacts 22b are arranged at intervals. In the present embodiment, the swinging direction of the swinging portion 40 is the circular track at the specific position when the circular track α of the contact portion 18 is viewed from a direction orthogonal to the surface 20a of the circuit board 20. It is the tangential direction of α (see the arrow in FIG. 5).

詳細には、回路基板２０の表面２０ａにおいて、前記特定の位置に中央接点２２ｃが配置される。そして、第１接点２２ａ及び第２接点２２ｂは、揺動方向に沿って中央接点２２ｃを挟み且つ中央接点２２ｃとそれぞれ間隔をおいて回路基板２０に配置される。本実施形態の各接点２２ａ，２２ｂ，２２ｃは、回路基板２０の表面２０ａ上に印刷されたカーボンで構成されている。接続用穴部２３は、回路基板２０において中央接点２２ｃの略中央位置に設けられ、回路基板２０の表面２０ａから当該回路基板２０の厚み方向に延びる穴部である。   Specifically, the center contact 22 c is disposed at the specific position on the surface 20 a of the circuit board 20. The first contact 22a and the second contact 22b are disposed on the circuit board 20 with the central contact 22c sandwiched in the swing direction and spaced from the central contact 22c. Each contact 22a, 22b, 22c of the present embodiment is made of carbon printed on the surface 20a of the circuit board 20. The connection hole 23 is a hole provided in the circuit board 20 at a substantially central position of the center contact 22 c and extending from the surface 20 a of the circuit board 20 in the thickness direction of the circuit board 20.

ラバーシート３０は、ゴム等の弾性部材により全体が比較的薄肉の略シート状に形成されたもので、操作パネルＰの裏側に回路基板２０が略平行に配置されたときに操作パネルＰと回路基板２０との間に挟み込まれる。具体的に、ラバーシート３０は、図７にも示されるように、ベース部３２と、回路基板２０の表面２０ａと直交する方向に延びて第１接点２２ａ及び第２接点２２ｂと対応する位置に第１可動接点４５ａ及び第２可動接点４５ｂをそれぞれ有する揺動部４０と、揺動部４０を揺動可能にベース部３２に連結する連結部３４とを一体に有する。   The rubber sheet 30 is formed in an approximately sheet shape with a relatively thin wall as a whole by an elastic member such as rubber. When the circuit board 20 is arranged substantially in parallel on the back side of the operation panel P, the rubber sheet 30 and the circuit are formed. It is sandwiched between the substrate 20. Specifically, as shown in FIG. 7, the rubber sheet 30 extends in a direction orthogonal to the base portion 32 and the surface 20 a of the circuit board 20 and is in a position corresponding to the first contact 22 a and the second contact 22 b. The oscillating portion 40 having the first movable contact 45a and the second movable contact 45b, respectively, and the connecting portion 34 for connecting the oscillating portion 40 to the base portion 32 so as to be oscillating are integrally provided.

尚、図１においては、ダイヤルスイッチ１２の周辺のみを示しているが、ラバーシート３０及びその裏側に配置されている回路基板２０は、その外側にも拡がっている。   In FIG. 1, only the periphery of the dial switch 12 is shown, but the rubber sheet 30 and the circuit board 20 disposed on the back side of the rubber sheet 30 also extend to the outside.

ベース部３２は、第１接点２２ａ、中央接点２２ｃ、及び第２接点２２ｂを含む領域を残してその外側の領域で回路基板２０の表面２０ａ上に敷設される部位である。即ち、ベース部３２には、当該ベース部３２を回路基板２０の表面２０ａ上に敷設したときに第１接点２２ａ、中央接点２２ｃ、及び第２接点２２ｂが露出するよう、前記の各接点を含む領域と対応する部位に空間が設けられたシート状の部位である（図３（Ｂ）参照）。この空間の周縁部（空間縁部）３３は、他の部位に比べて厚み寸法が小さく、即ち、薄肉になっている。このベース部３２は、操作パネルＰと回路基板２０との間に挟み込まれることにより、回路基板２０の表面２０ａに実装された光源についての遮光（当該光源から発せられる光の外部への漏れの阻止）や回路基板２０の表面２０ａに実装された電子部品の防水、押圧スイッチの構築等に用いられる。具体的に、ベース部３２（ラバーシート３０）は、例えば、図１に示される範囲の外側において、回路基板２０の表面２０ａに実装された電子部品等を覆ってこの電子部品等が水と接することを防いだり、回路基板２０の表面２０ａに実装された光源の周囲を囲うことで当該光源が発した光のうち操作パネルＰに向う光以外を遮光して、回路基板２０と操作パネルＰとの間に前記光源からの光が漏れ拡がらないようにしている。また、ベース部３２は、回路基板２０の表面２０ａに設けられた接点等と協働して押圧スイッチ等を構築する場合もある。   The base portion 32 is a portion that is laid on the surface 20a of the circuit board 20 in an outer region, leaving a region including the first contact 22a, the center contact 22c, and the second contact 22b. That is, the base portion 32 includes the above-described contacts so that the first contact 22a, the center contact 22c, and the second contact 22b are exposed when the base portion 32 is laid on the surface 20a of the circuit board 20. It is a sheet-like part in which a space is provided in a part corresponding to the region (see FIG. 3B). The peripheral edge portion (space edge portion) 33 of this space is smaller in thickness than other portions, that is, is thin. The base portion 32 is sandwiched between the operation panel P and the circuit board 20, thereby shielding light from the light source mounted on the surface 20 a of the circuit board 20 (preventing leakage of light emitted from the light source to the outside). ) And waterproofing of electronic components mounted on the surface 20a of the circuit board 20, construction of a push switch, and the like. Specifically, the base portion 32 (rubber sheet 30) covers, for example, the electronic components mounted on the surface 20a of the circuit board 20 outside the range shown in FIG. By blocking the periphery of the light source mounted on the surface 20a of the circuit board 20, the light emitted from the light source is shielded from light other than the light directed to the operation panel P, and the circuit board 20 and the operation panel P During this period, light from the light source is prevented from leaking and spreading. Moreover, the base part 32 may construct | assemble a press switch etc. in cooperation with the contact etc. which were provided in the surface 20a of the circuit board 20. FIG.

連結部３４は、ベース部３２よりもさらに薄肉のシート状の部位であり、弾性変形可能に揺動部４０の周面４１とベース部３２の空間縁部３３とを連結する。具体的に、連結部３４は、回路基板２０に対して起立した揺動部４０の周面４１とベース部３２の空間縁部３３とを揺動部４０の周方向の全域に亘って連結している。   The connecting portion 34 is a sheet-like portion that is thinner than the base portion 32 and connects the peripheral surface 41 of the swinging portion 40 and the space edge portion 33 of the base portion 32 so as to be elastically deformable. Specifically, the connecting portion 34 connects the peripheral surface 41 of the swinging portion 40 erected with respect to the circuit board 20 and the space edge portion 33 of the base portion 32 over the entire circumferential direction of the swinging portion 40. ing.

このように弾性変形可能な薄肉のシート状の連結部３４が揺動部４０をベース部３２に連結することにより、揺動部４０が揺動可能となる。具体的に、連結部３４は、回転部１６が図５において時計回り（第１の回転方向）に回転した状態で当接部１８が揺動部４０に当接することでこの揺動部４０がその先端を揺動方向に沿って一方（第１の方向：図５において下側）に向けて傾き第１可動接点４５ａが第１接点２２ａ及び中央接点２２ｃに接触する（図８（Ａ）及び図８（Ｂ）参照）のを弾性変形により許容すると共に、揺動部４０に当接した当接部１８が当該揺動部４０から離間することで第１の方向に傾いた揺動部４０を弾性復帰力により起立させて第１接点２２ａ及び中央接点２２ｃから第１可動接点４５ａを離間させる（図９（Ａ）〜図９（Ｄ）参照）。また、連結部３４は、回転部１６が図５において反時計回り（第２の回転方向）に回転した状態で当接部１８が揺動部４０に当接することでこの揺動部４０がその先端を揺動方向に沿って他方（第２の方向：図５において上側）に向けて傾き第２可動接点４５ｂが第２接点２２ｂ及び中央接点２２ｃに接触するのを弾性変形により許容すると共に、揺動部４０に当接した当接部１８が当該揺動部４０から離間することで第２の方向に傾いた揺動部４０を弾性復帰力により起立させて第２接点２２ｂ及び中央接点２２ｃから第２可動接点４５ｂを離間させる（図１０（Ａ）〜図１０（Ｂ）参照）。   By connecting the swinging portion 40 to the base portion 32 by the thin sheet-like connecting portion 34 that can be elastically deformed in this way, the swinging portion 40 can swing. Specifically, the connecting portion 34 is configured so that the abutting portion 18 abuts against the oscillating portion 40 in a state where the rotating portion 16 is rotated clockwise (first rotation direction) in FIG. The tip of the first movable contact 45a is tilted toward one side (first direction: lower side in FIG. 5) along the swinging direction, and contacts the first contact 22a and the center contact 22c (FIG. 8A and FIG. 8). 8B) is allowed by elastic deformation, and the abutting portion 18 that is in contact with the oscillating portion 40 is separated from the oscillating portion 40 so that the oscillating portion 40 is inclined in the first direction. Is raised by an elastic restoring force to separate the first movable contact 45a from the first contact 22a and the center contact 22c (see FIGS. 9A to 9D). Further, the connecting portion 34 is configured such that the swinging portion 40 is in contact with the swinging portion 40 in a state where the rotating portion 16 is rotated counterclockwise (second rotation direction) in FIG. The tip is inclined toward the other (second direction: upper side in FIG. 5) along the swinging direction, and the second movable contact 45b is allowed to contact the second contact 22b and the center contact 22c by elastic deformation, and The abutting portion 18 that abuts on the oscillating portion 40 moves away from the oscillating portion 40, so that the oscillating portion 40 tilted in the second direction is erected by an elastic return force, and the second contact 22b and the central contact 22c. The second movable contact 45b is moved away from (see FIGS. 10A to 10B).

尚、本実施形態では、回転部１６に並んでいる複数の当接部１８の各間隔を調節することにより、回転部１６が第１の回転方向に回転したときに、一つの当接部１８が揺動部４０に当接することにより当該揺動部４０を第１の方向に傾けたあと次の当接部１８が当該揺動部４０に当接するまでの間に当該揺動部４０が起立して第１可動接点４５ａと第１接点２２ａ及び中央接点２２ｃとが離間した状態となり、回転部１６が第２の回転方向に回転したときに、一つの当接部１８が揺動部４０に当接することにより当該揺動部４０を第２の方向に傾けたあと次の当接部１８が当該揺動部４０に当接するまでの間に当該揺動部４０が起立して第２可動接点４５ｂと第２接点２２ｂ及び中央接点２２ｃとが離間した状態となるようにしている。   In the present embodiment, by adjusting the intervals between the plurality of contact portions 18 arranged in the rotation portion 16, when the rotation portion 16 rotates in the first rotation direction, one contact portion 18. The swinging portion 40 is raised while the swinging portion 40 is tilted in the first direction until the next contact portion 18 comes into contact with the swinging portion 40. Thus, when the first movable contact 45a is separated from the first contact 22a and the center contact 22c, and the rotating part 16 rotates in the second rotational direction, one contact part 18 becomes the swinging part 40. After the tilting of the swinging part 40 in the second direction by the contact, the swinging part 40 rises until the next contact part 18 contacts the swinging part 40, and the second movable contact point. 45b is separated from the second contact 22b and the central contact 22c.

揺動部４０は、先端部が円形軌道αを通る当接部１８と当接するように回路基板２０の表面と直交する方向に沿って表面２０ａの近傍から円形軌道αまで延びる部位である。即ち、揺動部４０は、その回路基板側の端部がベース部３２の空間縁部３３に囲まれた領域内に位置し且つ先端が当接部１８の通る円形軌道α内に位置するような長さ寸法を有する。また、揺動部４０は、回路基板側の端部における第１接点２２ａ及び第２接点２２ｂと対応する位置に第１可動接点４５ａ及び第２可動接点４５ｂをそれぞれ有する。この揺動部４０は、回転部１６の回転に伴って各当接部１８が揺動部４０の先端部に次々に当接することにより揺動方向に沿って揺動する。   The swinging portion 40 is a portion that extends from the vicinity of the surface 20a to the circular track α along the direction orthogonal to the surface of the circuit board 20 so that the tip portion contacts the contact portion 18 that passes through the circular track α. That is, the oscillating portion 40 has an end on the circuit board side located in a region surrounded by the space edge portion 33 of the base portion 32 and a distal end located in a circular orbit α passing through the contact portion 18. Length. The swinging portion 40 has a first movable contact 45a and a second movable contact 45b at positions corresponding to the first contact 22a and the second contact 22b at the end on the circuit board side. The swinging portion 40 swings along the swinging direction as the abutting portions 18 successively come into contact with the tip end portions of the swinging portion 40 as the rotating portion 16 rotates.

具体的に、揺動部４０は、ベース部３２及び連結部３４と一体に形成されるラバー部４２と、導体によって形成され、ラバー部４２の回路基板側に接続される導体部４３とを有する。本実施形態のラバー部４２と導体部４３とは、接着により互いに接続されている。   Specifically, the swing part 40 includes a rubber part 42 formed integrally with the base part 32 and the coupling part 34, and a conductor part 43 formed of a conductor and connected to the circuit board side of the rubber part 42. . The rubber part 42 and the conductor part 43 of this embodiment are mutually connected by adhesion | attachment.

導体部４３は、第１可動接点４５ａ及び第２可動接点４５ｂを含む導体部本体４４と、この導体部本体４４から回路基板２０に向って延びる接続部４６とを有する。本実施形態の導体部本体４４と接続部４６とは、カーボンによって一体成形されている。導体部本体４４は、円盤状の部位４４ａと、この円盤状の部位４４ａの中央部から揺動部４０の先端側に向って延びる接続部位４４ｂとを有する。この接続部位４４ｂは、導体部４３をラバー部４２に接続するときにラバー部４２に対する導体部４３の位置決めを容易にするための部位であり、ラバー部４２の対応する位置に設けられた穴４２ａに嵌入される。   The conductor portion 43 includes a conductor portion main body 44 including a first movable contact 45 a and a second movable contact 45 b, and a connection portion 46 extending from the conductor portion main body 44 toward the circuit board 20. The conductor part main body 44 and the connection part 46 of this embodiment are integrally formed of carbon. The conductor main body 44 has a disk-shaped part 44a and a connection part 44b extending from the central part of the disk-shaped part 44a toward the distal end side of the swinging part 40. This connection part 44b is a part for facilitating positioning of the conductor part 43 with respect to the rubber part 42 when the conductor part 43 is connected to the rubber part 42, and a hole 42a provided at a corresponding position of the rubber part 42. Inserted.

また、導体部本体４４は、基板側接点２２と対向するように回路基板２０の表面２０ａ側を向いた基板側端面４５を有する。この基板側端面４５は、揺動方向の中央部に設けられた底面４５ｃと、この底面４５ｃを揺動方向に沿って挟む第１接触面１４５ａ及び第２接触面１４５ｂとを有する。本実施形態では、導体部４３の全体が導体（カーボン）で形成されているため、第１接触面１４５ａ及び第２接触面１４５ｂがそれぞれ接点の役割を果たすことができる。そこで、本実施形態では、第１接触面１４５ａが第１可動接点４５ａと用いられ、第２接触面１４５ｂが第２可動接点４５ｂとして用いられる。   The conductor main body 44 has a board-side end face 45 facing the front surface 20 a of the circuit board 20 so as to face the board-side contact 22. The substrate-side end surface 45 includes a bottom surface 45c provided at the center in the swing direction, and a first contact surface 145a and a second contact surface 145b that sandwich the bottom surface 45c along the swing direction. In this embodiment, since the whole conductor part 43 is formed with the conductor (carbon), the 1st contact surface 145a and the 2nd contact surface 145b can each play the role of a contact. Therefore, in the present embodiment, the first contact surface 145a is used as the first movable contact 45a, and the second contact surface 145b is used as the second movable contact 45b.

底面４５ｃは、回路基板２０の表面２０ａと平行な部位であり、接続部４６が設けられている。この接続部４６は、揺動部４０を回路基板２０に接続する部位であり、揺動部４０が揺動するときの支点となる。接続部４６は、底面４５ｃから回路基板２０の接続用穴部２３内に延び、当該接続部４６が接続用穴部２３に嵌入した状態で底面４５ｃが回路基板２０の表面２０ａと僅に離間した状態（図８（Ａ）参照）となるような長さ寸法を有する。また、接続部４６は、接続用穴部２３の内径に対応する外径を有し、揺動方向に撓み変形可能に構成される。   The bottom surface 45 c is a part parallel to the surface 20 a of the circuit board 20, and a connection portion 46 is provided. The connecting portion 46 is a portion that connects the swinging portion 40 to the circuit board 20 and serves as a fulcrum when the swinging portion 40 swings. The connection portion 46 extends from the bottom surface 45 c into the connection hole portion 23 of the circuit board 20, and the bottom surface 45 c is slightly separated from the surface 20 a of the circuit board 20 with the connection portion 46 fitted in the connection hole portion 23. It has a length dimension so as to be in a state (see FIG. 8A). Further, the connecting portion 46 has an outer diameter corresponding to the inner diameter of the connecting hole portion 23 and is configured to be able to bend and deform in the swinging direction.

第１可動接点４５ａ（第１接触面１４５ａ）及び第２可動接点４５ｂ（第２接触面１４５ｂ）は、第１接点２２ａ及び第２接点２２ｂと対応するように回路基板２０の表面２０ａ側を向き、底面４５ｃから揺動方向に沿って離れるに従って回路基板２０の表面２０ａからの距離が大きくなる傾斜面である。このように第１可動接点４５ａ及び第２可動接点４５ｂが表面２０ａに対して傾斜することにより、揺動部４０が回路基板２０に対して起立した姿勢では第１可動接点４５ａ及び第２可動接点４５ｂのいずれの面も回路基板２０の表面２０ａから離間し（図９（Ａ）参照）、揺動部４０が第１の方向（図９（Ｃ）では左側）に傾いて第１可動接点４５ａが回路基板２０の表面２０ａと接触したときに第２可動接点４５ｂが回路基板２０の表面２０ａから離間し（図９（Ｃ）参照）、揺動部４０が第２の方向（図１０（Ｃ）では右側）に傾いて第２可動接点４５ｂが回路基板２０の表面２０ａと接触したときに第１可動接点４５ａが回路基板２０の表面２０ａから離間する。   The first movable contact 45a (first contact surface 145a) and the second movable contact 45b (second contact surface 145b) face the surface 20a side of the circuit board 20 so as to correspond to the first contact 22a and the second contact 22b. The inclined surface is such that the distance from the surface 20a of the circuit board 20 increases as the distance from the bottom surface 45c increases in the swing direction. As described above, the first movable contact 45a and the second movable contact 45b are inclined with respect to the surface 20a, so that the first movable contact 45a and the second movable contact are in a posture in which the swinging portion 40 stands with respect to the circuit board 20. Both surfaces of 45b are separated from the surface 20a of the circuit board 20 (see FIG. 9A), and the swinging portion 40 is tilted in the first direction (left side in FIG. 9C) to be in contact with the first movable contact 45a. Is in contact with the surface 20a of the circuit board 20, the second movable contact 45b is separated from the surface 20a of the circuit board 20 (see FIG. 9C), and the swinging portion 40 is in the second direction (FIG. 10C). ) Is inclined to the right) and the first movable contact 45a is separated from the surface 20a of the circuit board 20 when the second movable contact 45b comes into contact with the surface 20a of the circuit board 20.

また、第１可動接点４５ａは、当該第１可動接点４５ａが回路基板２０の表面２０ａに接触したときに中央接点２２ｃと第１接点２２ａとに跨るように接触する形状を有する。そのため、揺動部４０が第１の方向に傾いて第１可動接点４５ａが回路基板２０の表面２０ａと接触すると、第１可動接点４５ａを介して中央接点２２ｃと第１接点２２ａとの間が導通状態となる。一方、第２可動接点４５ｂは、当該第２可動接点４５ｂが回路基板２０の表面２０ａに接触したときに中央接点２２ｃと第２接点２２ｂとに跨るように接触する形状を有する。そのため、揺動部４０が第２の方向に傾いて第２可動接点４５ｂが回路基板２０の表面２０ａと接触すると、第２可動接点４５ｂを介して中央接点と第２接点との間が導通状態となる。   The first movable contact 45a has a shape that contacts the central contact 22c and the first contact 22a when the first movable contact 45a contacts the surface 20a of the circuit board 20. Therefore, when the swinging portion 40 is tilted in the first direction and the first movable contact 45a comes into contact with the surface 20a of the circuit board 20, there is a gap between the central contact 22c and the first contact 22a via the first movable contact 45a. It becomes a conductive state. On the other hand, the second movable contact 45b has a shape that contacts the central contact 22c and the second contact 22b when the second movable contact 45b contacts the surface 20a of the circuit board 20. Therefore, when the swinging portion 40 is inclined in the second direction and the second movable contact 45b comes into contact with the surface 20a of the circuit board 20, the central contact and the second contact are in a conductive state via the second movable contact 45b. It becomes.

ラバー部４２は、先端部に円形軌道αを移動する当接部１８と当接可能な第１当接面４７ａ及び第２当接面４７ｂを有する。これら第１当接面４７ａ及び第２当接面４７ｂは、回転部１６の回転に伴って当接部１８が当接したときに、揺動部４０の傾く方向及び傾き度合いを規定するための面である。即ち、これら第１当接面４７ａ及び第２当接面４７ｂの形状（即ち、回路基板２０の表面２０ａに対する傾斜角や傾斜方向における長さ、当接面の向いている方向等）により、回転部の回転に基づく揺動部の揺動方向及び傾斜角が規定される。本実施形態の第１当接面４７ａ及び第２当接面４７ｂは、回路基板２０の表面２０ａに対して傾斜した平らな傾斜面である。   The rubber portion 42 has a first contact surface 47a and a second contact surface 47b that can contact the contact portion 18 that moves on the circular track α at the tip portion. The first contact surface 47a and the second contact surface 47b are used to define the direction and degree of inclination of the swinging part 40 when the contact part 18 comes into contact with the rotation of the rotary part 16. Surface. That is, the rotation depends on the shape of the first contact surface 47a and the second contact surface 47b (that is, the tilt angle with respect to the surface 20a of the circuit board 20, the length in the tilt direction, the direction in which the contact surface faces, etc.). A swing direction and an inclination angle of the swing part based on the rotation of the part are defined. The first contact surface 47 a and the second contact surface 47 b of the present embodiment are flat inclined surfaces that are inclined with respect to the surface 20 a of the circuit board 20.

具体的に、第１当接面４７ａは、回転部１６が第１の回転方向に回転したときに各当接部１８が当接可能な方向を向き、第２当接面４７ｂは、回転部１６が第２の回転方向に回転したときに各当接部１８が当接可能な方向を向いている。詳しくは、第１当接面４７ａは、揺動部４０の先端側且つ第２の方向を向いた傾斜面であり、第２当接面４７ｂは、揺動部４０の先端側且つ第１の方向を向いた傾斜面である。これら第１当接面４７ａ及び第２当接面４７ｂは、回路基板２０と直交する方向から揺動部４０を見たときに、先端側の端部同士を当接させて互いに背中合わせとなるように揺動部４０の先端部に設けられる。   Specifically, the first contact surface 47a faces a direction in which each contact portion 18 can contact when the rotation portion 16 rotates in the first rotation direction, and the second contact surface 47b indicates the rotation portion. When 16 rotates in the 2nd rotation direction, it has faced the direction which each contact part 18 can contact. Specifically, the first contact surface 47a is an inclined surface facing the tip side of the swinging portion 40 and in the second direction, and the second contact surface 47b is a tip side of the swinging portion 40 and the first surface. It is an inclined surface facing the direction. The first contact surface 47a and the second contact surface 47b are configured such that when the swinging portion 40 is viewed from a direction orthogonal to the circuit board 20, the end portions on the front end side are in contact with each other and are back to back. Is provided at the tip of the swinging portion 40.

このような形状の第１当接面４７ａによれば、回転部１６が第１の回転方向へ回転することで当接部１８が第１当接面４７ａに当接し、この当接部１８が第１当接面４７ａ上を当該第１当接面４７ａに沿って通過することにより、揺動部４０がその先端を第１の方向に向けて傾き第１可動接点４５ａが回路基板２０の表面２０ａ（詳細には、第１接点２２ａ及び中央接点２２ｃ）に接触する（図９（Ａ）〜図９（Ｄ）参照）。また前記の第２当接面４７ｂによれば、回転部１６が第２の回転方向へ回転することで当接部１８が第２当接面４７ｂに当接し、この当接部１８が第２当接面４７ｂ上を当該第２当接面４７ｂに沿って通過することにより、揺動部４０がその先端を第２の方向に向けて傾き第２可動接点４５ｂが回路基板２０の表面２０ａ（詳細には、第２接点２２ｂ及び中央接点２２ｃ）に接触する（図１０（Ａ）〜図１０（Ｄ）参照）。   According to the first contact surface 47a having such a shape, the rotation portion 16 rotates in the first rotation direction, so that the contact portion 18 contacts the first contact surface 47a. By passing the first abutting surface 47a along the first abutting surface 47a, the oscillating portion 40 is inclined with the tip thereof directed in the first direction, and the first movable contact 45a is the surface of the circuit board 20. 20a (specifically, the first contact 22a and the center contact 22c) (see FIGS. 9A to 9D). Further, according to the second contact surface 47b, the rotation portion 16 rotates in the second rotation direction, so that the contact portion 18 contacts the second contact surface 47b. By passing on the contact surface 47b along the second contact surface 47b, the swinging portion 40 tilts its tip toward the second direction, and the second movable contact 45b becomes the surface 20a ( Specifically, the second contact 22b and the center contact 22c) are contacted (see FIGS. 10A to 10D).

このように、当接部１８が揺動部４０に当接したときの当該揺動部４０の傾く方向や傾き度合い等を揺動部４０の先端側に設けられた二つの面（第１当接面４７ａ及び第２当接面４７ｂ）によって調整可能にすることで、当該検知機構１０の構成の簡素化を図ることができる。   As described above, when the abutting portion 18 abuts on the oscillating portion 40, the direction in which the oscillating portion 40 inclines, the degree of inclination, and the like are determined on two surfaces (first contact) By making adjustment possible by the contact surface 47a and the second contact surface 47b), the configuration of the detection mechanism 10 can be simplified.

以上のようなラバーシート３０は、揺動部４０の導体部４３を除いた部位（即ち、ベース部３２、連結部３４、及び揺動部４０のラバー部４２）がプレスや射出成形等によって一体成形され、この成形体に別途に成形された導体部４３が取り付けられることにより製造される。   In the rubber sheet 30 as described above, the portions (that is, the base portion 32, the connecting portion 34, and the rubber portion 42 of the swinging portion 40) excluding the conductor portion 43 of the swinging portion 40 are integrated by pressing, injection molding, or the like. It is manufactured by molding and attaching a conductor part 43 separately molded to this molded body.

次に、当該検知機構１０によるダイヤルノブ１４の回転方向及び回転量の検知方法について説明する。   Next, a method for detecting the direction and amount of rotation of the dial knob 14 by the detection mechanism 10 will be described.

ダイヤルノブ１４が回転操作される前の初期状態では、揺動部４０は、回路基板２０に対して起立した状態（起立状態）である（図９（Ａ）及び図１０（Ａ）参照）。この起立状態では、第１可動接点４５ａ及び第２可動接点４５ｂがいずれも回路基板２０の表面２０ａと離間している。   In an initial state before the dial knob 14 is rotated, the swinging portion 40 is in a standing state (standing state) with respect to the circuit board 20 (see FIGS. 9A and 10A). In this standing state, the first movable contact 45 a and the second movable contact 45 b are both separated from the surface 20 a of the circuit board 20.

操作者がダイヤルノブ１４を時計回り（第１の回転方向）に回転操作すると、ダイヤルノブ１４の回転と一体に回転部１６が回転する。この回転部１６の回転に伴って一つの当接部１８が第１当接面４７ａに当接する（図９（Ｂ）参照）。この状態から更に回転部１６が回転して当接している当接部１８が移動すると、この当接部１８によって揺動部４０が先端部（第１当接面４７ａ）を第１の方向に押される。このとき、第１当接面４７ａの形状等によって揺動部４０の傾く方向や傾き度合いが規定されるが、本実施形態の第１当接面４７ａによれば、揺動部４０が先端部を第１の方向へ向けて傾く共に第１可動接点４５ａが回路基板２０の表面２０ａに接触するまで傾く（図９（Ｃ）参照）。このとき、揺動部４０が傾くのに伴って連結部３４が弾性変形すると共に接続部４６が撓み変形する。第１可動接点４５ａが回路基板２０の表面２０ａに接触すると、第１可動接点４５ａが第１接点２２ａと中央接点２２ｃとに跨るように接触する。これにより、第１可動接点４５ａを介して第１接点２２ａと中央接点２２ｃとの間が導通状態となる。   When the operator rotates the dial knob 14 clockwise (first rotation direction), the rotating unit 16 rotates together with the rotation of the dial knob 14. As the rotating portion 16 rotates, one contact portion 18 contacts the first contact surface 47a (see FIG. 9B). From this state, when the rotating portion 16 further rotates and contacts the contacting portion 18, the contacting portion 18 causes the swinging portion 40 to move the tip portion (first contacting surface 47 a) in the first direction. Pressed. At this time, the inclination direction and the degree of inclination of the swinging portion 40 are defined by the shape of the first contact surface 47a and the like, but according to the first contact surface 47a of the present embodiment, the swinging portion 40 is the tip portion. And the first movable contact 45a is inclined until it contacts the surface 20a of the circuit board 20 (see FIG. 9C). At this time, the connecting portion 34 is elastically deformed and the connecting portion 46 is bent and deformed as the swinging portion 40 is tilted. When the first movable contact 45a contacts the surface 20a of the circuit board 20, the first movable contact 45a comes into contact with the first contact 22a and the central contact 22c. Thereby, between the 1st contact 22a and the center contact 22c will be in a conduction state via the 1st movable contact 45a.

更に回転部１６が回転すると、第１当接面４７ａが当接部１８によって更に回路基板側に押されて揺動部４０（ラバー部４２）が弾性変形し、これにより当接部１８の第１当接面４７ａ上の通過が許容される。このとき、前記の弾性変形に基づく揺動部４０（ラバー部４２）の弾発力により第１可動接点４５ａ（第１接触面１４５ａ）が回路基板２０の表面２０ａに対して十分な力で押し付けられ、その結果、第１可動接点４５ａと第１接点２２ａ及び中央接点２２ｃとが確実に接触する。   When the rotating portion 16 further rotates, the first abutting surface 47a is further pushed toward the circuit board by the abutting portion 18, and the swinging portion 40 (rubber portion 42) is elastically deformed. 1 The passage on the contact surface 47a is allowed. At this time, the first movable contact 45a (first contact surface 145a) is pressed against the surface 20a of the circuit board 20 with sufficient force by the elastic force of the swinging portion 40 (rubber portion 42) based on the elastic deformation. As a result, the first movable contact 45a, the first contact 22a, and the center contact 22c are reliably in contact with each other.

更に回転部１６が回転して当接部１８が第１当接面４７ａ上を通過したあと、弾性変形した連結部３４の弾性復帰力（弾発力）及び撓み変形した接続部４６の弾性復帰力（弾発力）によって揺動部４０が起こされる。ここで、本実施形態では、回転部１６が回転し続けたときに、一つの当接部１８が第１当接面４７ａに当接したあと次の当接部１８が第１当接面４７ａに当接するまでの間に揺動部４０が起立して第１可動接点４５ａと第１接点２２ａ及び中央接点２２ｃとが離間した状態となるような間隔で複数の当接部１８が回転部１６に並んでいる。そのため、前記の連結部３４及び接続部４６の弾性復帰力により起こされた揺動部４０は、次の当接部１８が当接する前に第１可動接点４５ａが第１接点２２ａ及び中央接点２２ｃと離間する角度まで起き上がる。   Further, after the rotating portion 16 rotates and the contact portion 18 passes over the first contact surface 47a, the elastic return force (elastic force) of the elastically deformed connection portion 34 and the elastic return of the connection portion 46 that is bent and deformed. The swinging portion 40 is raised by force (elastic force). Here, in this embodiment, when the rotating portion 16 continues to rotate, the next contact portion 18 contacts the first contact surface 47a after the one contact portion 18 contacts the first contact surface 47a. The abutting portions 18 are erected until the first movable contact 45a and the first contact 22a and the center contact 22c are separated from each other until the swinging portion 40 stands up until the rotating portion 16 comes into contact with the rotating portion 16. Are lined up. Therefore, in the swinging portion 40 caused by the elastic restoring force of the connecting portion 34 and the connecting portion 46, the first movable contact 45a becomes the first contact 22a and the central contact 22c before the next contact portion 18 contacts. Get up to an angle that separates.

ダイヤルノブ１４の回転操作により回転部１６が第１の回転方向に回転し続けている間、上記のような、１）第１当接面４７ａへ当接部１８が当接し（図９（Ｂ）参照）、２）この当接部１８に押されて揺動部４０が第１の方向へ傾くことにより第１可動接点４５ａが第１接点２２ａと中央接点２２ｃとの間を導通させ（図９（Ｃ）参照）、３）第１当接面４７ａ上を当接部１８が通過したあと、次の当接部１８が当該第１当接面４７ａに当接するまでの間に揺動部４０が起立して第１可動接点４５ａが回路基板２０から離間し、第１接点２２ａと中央接点２２ｃとの間が非導通状態に戻る（図９（Ｄ）参照）、といった一連の動作が繰り返される。   While the rotating portion 16 continues to rotate in the first rotation direction by the rotation operation of the dial knob 14, the contact portion 18 contacts the first contact surface 47a as described above (FIG. 9B). 2) The first movable contact 45a is electrically connected between the first contact 22a and the central contact 22c by being pushed by the contact portion 18 and tilting the swinging portion 40 in the first direction (see FIG. 9) (3) After the contact portion 18 has passed over the first contact surface 47a, the swinging portion until the next contact portion 18 contacts the first contact surface 47a. 40 is erected, the first movable contact 45a is separated from the circuit board 20, and the first contact 22a and the central contact 22c return to a non-conducting state (see FIG. 9D). It is.

一方、ダイヤルノブ１４が反時計回り（第２の回転方向）に回転操作されると、時計回りに回転操作されたときと同様に、１）第２当接面４７ｂへ当接部１８が当接し（図１０（Ｂ）参照）、２）この当接部１８に押されて揺動部４０が第２の方向へ傾くことにより第２可動接点４５ｂが第２接点２２ｂと中央接点２２ｃとの間を導通させ（図１０（Ｃ）参照）、３）第２当接面４７ｂ上を当接部１８が通過したあと、次の当接部１８が当該第２当接面４７ｂに当接するまでの間に揺動部４０が起立して第２可動接点４５ｂが回路基板２０の表面２０ａから離間し、第２接点２２ｂと中央接点２２ｃとの間が非導通状態に戻る（図１０（Ｄ）参照）、といった一連の動作が繰り返される。   On the other hand, when the dial knob 14 is rotated counterclockwise (second rotational direction), as in the case where the dial knob 14 is rotated clockwise, 1) the contact portion 18 contacts the second contact surface 47b. 2) The second movable contact 45b is pushed between the second contact 22b and the center contact 22c by being pushed by the contact portion 18 and tilting the swinging portion 40 in the second direction. 3) Until the next contact portion 18 contacts the second contact surface 47b after the contact portion 18 passes over the second contact surface 47b. During this time, the oscillating portion 40 stands and the second movable contact 45b is separated from the surface 20a of the circuit board 20, and the second contact 22b and the center contact 22c return to a non-conductive state (FIG. 10D). A series of operations are repeated.

このとき、いずれの接点同士が接触したか、即ち、回路基板２０に設けられた各接点２２ａ，２２ｂ，２２ｃ間の導通状態が検出されることで、ダイヤルノブ１４の回転方向が検知され、その接触回数（導通回数）によってダイヤルノブ１４の回転量が検知される。   At this time, the contact direction between the contacts 22a, 22b, and 22c provided on the circuit board 20 is detected by detecting which contacts are in contact with each other, thereby detecting the rotation direction of the dial knob 14. The amount of rotation of the dial knob 14 is detected based on the number of times of contact (number of times of conduction).

以上のように、本実施形態に係る検知機構１０によれば、ダイヤルノブ１４の回転操作によって当接部１８が揺動部４０に次々に当接して揺動部４０が揺動することで、ダイヤルノブ１４の回転方向及び回転量の両方をそれぞれ検知することができる。しかも、操作パネルＰの裏側に回路基板２０が配置されたときにこの回路基板２０の防水や遮光のために当該回路基板２０と操作パネルＰとの間に配設される弾性シート３０の一部を利用して検知機構１０を構成させることで、コストの削減を図ることができる。   As described above, according to the detection mechanism 10 according to the present embodiment, when the dial knob 14 is rotated, the contact portion 18 contacts the swing portion 40 one after another, and the swing portion 40 swings. Both the rotation direction and the rotation amount of the dial knob 14 can be detected. In addition, when the circuit board 20 is disposed on the back side of the operation panel P, a part of the elastic sheet 30 disposed between the circuit board 20 and the operation panel P for waterproofing or shielding the circuit board 20. The cost can be reduced by configuring the detection mechanism 10 using.

また、前記の検知機構１０によれば、揺動部４０が接続部４６により回路基板２０に接続されることによって、揺動部４０が傾いたときに第１可動接点又は第２可動接点が回路基板２０上の対応する接点と確実に接触する。即ち、揺動部４０が当接部１８により押し倒されたときにこの接続部４６を支点に揺動部４０が倒れることで、揺動部４０と回路基板２０との回路基板２０の表面２０ａに沿った方向の相対位置がずれるのを防止することができる。これにより、揺動部４０が傾いたときに、第１可動接点４５ａと第１接点２２ａ及び中央接点２２ｃとが確実に接触し、又は、第２可動接点４５ｂと第２接点２２ｂ及び中央接点２２ｃとが確実に接触する。   Further, according to the detection mechanism 10 described above, the swinging part 40 is connected to the circuit board 20 by the connecting part 46, so that the first movable contact or the second movable contact is connected to the circuit when the swinging part 40 is tilted. Reliable contact with corresponding contacts on the substrate 20. That is, when the swinging portion 40 is pushed down by the contact portion 18, the swinging portion 40 is tilted with the connecting portion 46 as a fulcrum, so that the surface 20 a of the circuit board 20 between the swinging portion 40 and the circuit board 20 is placed. It is possible to prevent the relative position in the direction along the direction from deviating. Thereby, when the swinging part 40 is tilted, the first movable contact 45a, the first contact 22a and the central contact 22c are surely contacted, or the second movable contact 45b, the second contact 22b and the central contact 22c. And contact with each other.

また、前記の検知機構１０によれば、第１可動接点４５ａ（第１接触面１４５ａ）及び第２可動接点４５ｂ（第２接触面１４５ｂ）が傾斜方向が反対の傾斜面によりそれぞれ構成されることによって、揺動部４０が傾いて第１可動接点４５ａが回路基板２０の表面２０ａに接触したときに第２可動接点４５ｂが回路基板２０の表面２０ａから離間し、又は第２可動接点４５ｂが回路基板２０の表面２０ａに接触したときに第１可動接点４５ａが回路基板２０の表面２０ａから離間する。そのため、ダイヤルノブ１４の回転方向及び回転量の誤検知を好適に抑止することができる。即ち、揺動部４０が第１の方向に傾いて第１可動接点４５ａが回路基板２０の表面２０ａに接触することで第１接点２２ａと中央接点２２ｃとの間が導通状態となったときに第２可動接点４５ｂが回路基板２０の表面２０ａから離間して第２接点２２ｂと中央接点２２ｃとの間が確実に非導通状態となる。一方、揺動部４０が第２の方向に傾いて第２可動接点４５ｂが回路基板２０の表面２０ａに接触して第２接点２２ｂと中央接点２２ｃとの間が導通状態のときに第１可動接点４５ａが回路基板２０の表面２０ａから離間して第１接点２２ａと中央接点２２ｃとの間が確実に非導通状態となる。   Further, according to the detection mechanism 10, the first movable contact 45 a (first contact surface 145 a) and the second movable contact 45 b (second contact surface 145 b) are respectively configured by inclined surfaces having opposite inclination directions. Thus, when the swinging portion 40 is tilted and the first movable contact 45a contacts the surface 20a of the circuit board 20, the second movable contact 45b is separated from the surface 20a of the circuit board 20, or the second movable contact 45b is connected to the circuit. The first movable contact 45a is separated from the surface 20a of the circuit board 20 when contacting the surface 20a of the board 20. Therefore, erroneous detection of the rotation direction and the rotation amount of the dial knob 14 can be suitably suppressed. That is, when the swinging portion 40 is tilted in the first direction and the first movable contact 45a comes into contact with the surface 20a of the circuit board 20, the first contact 22a and the central contact 22c are in a conductive state. The second movable contact 45b is separated from the surface 20a of the circuit board 20, and the second contact 22b and the center contact 22c are surely disconnected. On the other hand, when the swinging portion 40 is tilted in the second direction, the second movable contact 45b contacts the surface 20a of the circuit board 20, and the first movable when the second contact 22b and the central contact 22c are in a conductive state. The contact 45a is separated from the surface 20a of the circuit board 20, and the first contact 22a and the center contact 22c are surely disconnected.

このように第１可動接点４５ａと第２可動接点４５ｂとがそれぞれ傾斜面で構成される場合、第１可動接点４５ａと第２可動接点４５ｂとが一体に形成されても、揺動部４０の傾く方向に応じて第１接点２２ａと中央接点２２ｃとの間、又は第２接点２２ｂと中央接点２２ｃとの間のいずれか一方の接点間しか導通状態とならない。これにより、二つの可動接点４５ａ，４５ｂを一体に形成、即ち、第１可動接点４５ａと第２可動接点４５ｂとの間が導通していても、ダイヤルノブ１４の回転方向や回転量の誤検知が防止できる。また、二つの可動接点４５ａ，４５ｂを一体に形成することにより部品点数の削減や構成の簡素化を図ることも可能となる。   As described above, when the first movable contact 45a and the second movable contact 45b are each formed of an inclined surface, even if the first movable contact 45a and the second movable contact 45b are integrally formed, Only one of the contacts between the first contact 22a and the center contact 22c or between the second contact 22b and the center contact 22c is brought into conduction according to the tilting direction. Thereby, the two movable contacts 45a and 45b are integrally formed, that is, even if the first movable contact 45a and the second movable contact 45b are electrically connected, erroneous detection of the rotation direction or amount of rotation of the dial knob 14 is detected. Can be prevented. In addition, by forming the two movable contacts 45a and 45b integrally, the number of parts can be reduced and the configuration can be simplified.

尚、本発明の操作パネルに配設された回転操作部材の回転方向及び回転量を検知する検知機構は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   The detection mechanism for detecting the rotation direction and the rotation amount of the rotary operation member disposed on the operation panel of the present invention is not limited to the above-described embodiment, and various detection mechanisms can be used without departing from the scope of the present invention. Of course, changes can be made.

上記の実施形態の操作パネルＰには、１つの回転操作部材（ダイヤルノブ）１４が配設されているが、これに限定されず、複数の回転操作部材１４が配設されてもよい。この場合、各回転操作部材１４に対応するように検知機構１０を操作パネルＰの裏側にそれぞれ配置することにより、各回転操作部材１４の回転方向及び回転量をそれぞれ検知することができる。   Although one rotation operation member (dial knob) 14 is disposed on the operation panel P of the above embodiment, the present invention is not limited to this, and a plurality of rotation operation members 14 may be disposed. In this case, by arranging the detection mechanism 10 on the back side of the operation panel P so as to correspond to each rotation operation member 14, the rotation direction and the rotation amount of each rotation operation member 14 can be detected.

上記の実施形態における第１当接面及び第２当接面の形状は、揺動部４０の揺動方向が回路基板２０と直交する方向から見たときに当接部１８の円形軌道αの接線方向となるようにそれぞれ構成されているが、これに限定されず、揺動部４０の揺動方向が円形軌道αの直径方向となるように構成されてもよい。具体的に、例えば、図１１に示されるように、揺動部４０を上記の実施形態での姿勢から当該揺動部４０をその中心軸を回転中心にして４５°回転させた姿勢で配置する。即ち、揺動部４０の先端において第１当接面４７ａの先端と第２当接面４７ｂの先端との境界に形成される峰部５０が円形軌道αの接線方向に対して４５°となるような姿勢で揺動部４０が配置される。これにより、回転部１６が時計回りに回転して当接部１８が第１当接面４７ａに当接すると、揺動部４０は、その先端を円形軌道αの中心側（図１１の矢印β側）に向けて傾く。一方、回転部１６が反時計回りに回転して当接部１８が第２当接面４７ｂに当接すると、揺動部４０は、その先端を円形軌道αの径方向外側（図１１の矢印γ側）に向けて傾く。   The shape of the first contact surface and the second contact surface in the above embodiment is such that the circular orbit α of the contact portion 18 when the swing direction of the swing portion 40 is viewed from a direction orthogonal to the circuit board 20. Although each is configured to be in the tangential direction, the present invention is not limited to this, and the swinging direction of the swinging portion 40 may be configured to be the diameter direction of the circular track α. Specifically, for example, as shown in FIG. 11, the swinging unit 40 is disposed in a posture rotated from the posture in the above-described embodiment by 45 ° around the central axis of the swinging unit 40. . That is, the peak 50 formed at the boundary between the tip of the first contact surface 47a and the tip of the second contact surface 47b at the tip of the swinging portion 40 is 45 ° with respect to the tangential direction of the circular orbit α. The swinging part 40 is arranged in such a posture. As a result, when the rotating portion 16 rotates clockwise and the abutting portion 18 abuts on the first abutting surface 47a, the swinging portion 40 has its tip at the center side of the circular orbit α (arrow β in FIG. 11). Tilt toward the side. On the other hand, when the rotating portion 16 rotates counterclockwise and the abutting portion 18 abuts on the second abutting surface 47b, the oscillating portion 40 has its tip end radially outward of the circular track α (arrow in FIG. 11). Tilt toward (γ side).

回転部に設けられる当接部の具体的な形状は限定されない。例えば、上記の実施形態の回転部１６では、各当接部１８が回転部１６から回路基板２０に向けて突出する突出片により構成されているが、図１２に示すように、回転部１６の径方向に突出する突出片１８ａにより構成されてもよい。また、当接部１８は、突出片で構成される必要もない。即ち、当接部は、回転部１６が回転したときに円形軌道αを通り、揺動部の先端部に間欠的に当接するように構成されていればよい。   The specific shape of the contact part provided in a rotation part is not limited. For example, in the rotating part 16 of the above embodiment, each contact part 18 is configured by a protruding piece that protrudes from the rotating part 16 toward the circuit board 20, but as shown in FIG. You may be comprised by the protrusion piece 18a which protrudes to radial direction. Moreover, the contact part 18 does not need to be comprised by a protrusion piece. That is, the abutting portion only needs to be configured to pass through the circular track α when the rotating portion 16 rotates and to intermittently abut the tip of the swinging portion.

揺動部４０の先端部に設けられる第１当接面及び第２当接面の具体的形状は、限定されない。例えば、上記の実施形態では、第１当接面４７ａ及び第２当接面４７ｂは、断面形状が真っ直ぐな傾斜面であるが、断面形状が外側に膨出するような曲面１４７ａ，１４７ｂ（図１３（Ａ）参照）であってもよく、内側に窪んだ曲面２４７ａ，２４７ｂ（図１３（Ｂ）参照）であってもよい。また、上記の実施形態では、揺動部４０の先端は、第１当接面４７ａの先端と第２当接面４７ｂの先端とが当接して断面が尖った形状となっているが、図１３（Ｃ）に示されるように、第１当接面３４７ａの先端と第２当接面３４７ｂの先端とが回路基板２０の表面２０ａに沿った方向に離れていてもよい。即ち、第１当接面と第２当接面とは、当接部が当接したときに、回転部の回転方向によって揺動部の傾く方向が反対となり、且つ、揺動部が傾いたときに揺動部の可動接点と回路基板の基板側接点とが互いに接触するような形状であればよい。   Specific shapes of the first contact surface and the second contact surface provided at the tip of the swinging portion 40 are not limited. For example, in the above-described embodiment, the first contact surface 47a and the second contact surface 47b are inclined surfaces having straight cross-sectional shapes, but curved surfaces 147a and 147b (see FIG. 13 (A)) or curved surfaces 247a and 247b (see FIG. 13B) recessed inward. Further, in the above-described embodiment, the tip of the swinging portion 40 has a shape in which the tip of the first contact surface 47a and the tip of the second contact surface 47b come into contact with each other and the cross section is sharp. 13C, the tip of the first contact surface 347a and the tip of the second contact surface 347b may be separated in a direction along the surface 20a of the circuit board 20. That is, when the abutting portion comes into contact with the first abutting surface and the second abutting surface, the direction in which the oscillating portion inclines is opposite depending on the rotation direction of the rotating portion, and the oscillating portion is inclined. It is sufficient that the movable contact of the swinging part and the board-side contact of the circuit board are sometimes in contact with each other.

揺動部４０の回路基板側の端部に設けられる第１可動接点及び第２可動接点の具体的構成は限定されない。例えば、上記の実施形態では、導体部４３の回路基板側の面１４５ａ、１４５ｂにより第１可動接点４５ａ及び第２可動接点４５ｂが構成されているが、図１４に示されるように、揺動部４０ｄの略全体を弾性体で形成し、この揺動部４０ｄの回路基板側の端部において第１接点２２ａ及び第２接点２２ｂを望む第１接触面１４５ａ及び第２接触面１４５ｂ上に導体で形成された層５１ａ，５１ｂをそれぞれ形成し、これを第１可動接点及び第２可動接点としてもよい。この場合、第１接触面１４５ａ及び第２接触面１４５ｂの略全体に導体で形成された層５１ａ，５１ｂが形成されてもよく、また、回路基板２０の表面２０ａに第１接触面１４５ａ（又は第２接触面１４５ｂ）が接触したときに中央接点２２ｃと第１接点２２ａ（又は第２接点２２ｂ）とを跨ぐように接触できる範囲で第１接触面１４５ａ（又は第２接触面１４５ｂ）の一部に導体による層が形成されてもよい。また、第１可動端子５１ａと第２可動端子５１ｂとの間は、導通されてなくてもよい。即ち、第１可動端子５１ａと第２可動端子５１ｂは、互いに導通可能に（一体に）形成されてもよく、別々に形成されてもよい。   The specific configurations of the first movable contact and the second movable contact provided at the end of the oscillating unit 40 on the circuit board side are not limited. For example, in the above embodiment, the first movable contact 45a and the second movable contact 45b are configured by the circuit board side surfaces 145a and 145b of the conductor portion 43. However, as shown in FIG. 40d is formed of an elastic body, and a conductor is provided on the first contact surface 145a and the second contact surface 145b where the first contact 22a and the second contact 22b are desired at the end of the swinging portion 40d on the circuit board side. The formed layers 51a and 51b may be formed and used as the first movable contact and the second movable contact. In this case, layers 51a and 51b made of a conductor may be formed on substantially the entire first contact surface 145a and second contact surface 145b, and the first contact surface 145a (or the surface 20a of the circuit board 20 may be formed). One of the first contact surfaces 145a (or the second contact surface 145b) within a range that can contact the center contact 22c and the first contact 22a (or the second contact 22b) when the second contact surface 145b) contacts. A layer made of a conductor may be formed on the part. Further, the first movable terminal 51a and the second movable terminal 51b may not be electrically connected. That is, the first movable terminal 51a and the second movable terminal 51b may be formed so as to be conductive to each other (integrally) or may be formed separately.
