Description

本発明は、映像装置、特に、ユーザからの操作を受け付けるスイッチを有する映像装置に関する。   The present invention relates to a video apparatus, and more particularly to a video apparatus having a switch that accepts an operation from a user.

ユーザからの操作を受け付けるスイッチの従来例が、例えば、特許文献１及び２に記載されている。特許文献１に記載されたスイッチでは、スイッチ軸としてのプランジャの先端に反射部を設け、反射部に対向する位置に一対の発光素子及び受光素子を配置している。この構成では、発光素子から出力した光を反射部で反射させ、その反射光を受光素子で受光している。ユーザからの操作に応じてプランジャが移動すると、その移動に連動して反射部の位置も移動するため、受光素子で検知する反射光の強度が変化し、その強度に応じてスイッチのＯＮ／ＯＦＦを検知している。特許文献２に記載されたスイッチは、特許文献１に記載された構造と略同一の構造を有し、発光素子の発光量を直接検知するモニタ用の受光素子をさらに設け、発光素子の発光量が一定になるようにフィードバック制御している。
特開平２−３０９５１７号公報（第１−３頁、第１−５図） 特開平２−１９２６２９号公報（第２−３頁、第１−２図） For example, Patent Documents 1 and 2 describe conventional examples of a switch that receives an operation from a user. In the switch described in Patent Document 1, a reflecting portion is provided at the tip of a plunger serving as a switch shaft, and a pair of light emitting elements and light receiving elements are disposed at positions facing the reflecting portion. In this configuration, the light output from the light emitting element is reflected by the reflecting portion, and the reflected light is received by the light receiving element. When the plunger moves according to the operation from the user, the position of the reflecting portion also moves in conjunction with the movement, so that the intensity of the reflected light detected by the light receiving element changes, and the switch is turned ON / OFF according to the intensity. Is detected. The switch described in Patent Document 2 has substantially the same structure as that described in Patent Document 1, and further includes a light receiving element for monitoring that directly detects the light emission amount of the light emitting element, and the light emission amount of the light emitting element. Is controlled so that is constant.

ところで、テレビ受像機や映像再生装置等の映像装置では、ＯＮ／ＯＦＦの検知だけでなく、スイッチの操作量を多段階に検知し、操作量に基づいてよりきめ細かな制御を行いたい場合がある。上記構成において操作量を多段階に検知するためには、受光強度の閾値を複数設定し、受光強度と各閾値との大小関係を検知する必要があるが、操作量に対して反射光強度の変化が緩やかである場合には各閾値との大小関係を正確に検知することが困難である。また、特許文献２に記載されているように発光量を一定に保つようにフィードバック制御すれば、発光素子の発光量の個体間でのばらつきを抑制することは可能であるが、操作量に対する反射強度の変化が緩やかであれば各閾値との大小関係を正確に検知することは困難である。   By the way, in a video apparatus such as a television receiver or a video reproduction apparatus, there is a case where it is desired not only to detect ON / OFF, but also to detect the operation amount of the switch in multiple stages and perform finer control based on the operation amount. . In the above configuration, in order to detect the operation amount in multiple stages, it is necessary to set a plurality of threshold values of the received light intensity and detect the magnitude relationship between the received light intensity and each threshold value. When the change is gradual, it is difficult to accurately detect the magnitude relationship with each threshold value. In addition, if feedback control is performed so as to keep the light emission amount constant as described in Patent Document 2, it is possible to suppress variation among the light emission amounts of the light emitting elements, but the reflection with respect to the operation amount. If the change in intensity is slow, it is difficult to accurately detect the magnitude relationship with each threshold value.

本発明は、映像装置において、スイッチの操作量の検知の精度を向上させることにある。   An object of the present invention is to improve the accuracy of detecting the operation amount of a switch in a video apparatus.

第１発明に係る映像装置は、ユーザの操作量を多段階に検知するスイッチを有する映像装置であって、スイッチ本体と、スイッチ本体に往復移動可能に装着されたスイッチ軸と、スイッチ軸の移動に連動して移動する反射板と、反射板に向けて光を出力する発光素子と、反射板からの反射光を検知して電気的な信号に変換する複数の受光素子と、スイッチ軸の移動量と各受光素子とを対応させたテーブルと、各受光素子からの信号に基づいてどの受光素子が反射光を検知したかを決定し、テーブルを参照して該受光素子に対応する前記移動量を算出する移動量検出部と、を備えることを特徴とする。
A video device according to a first aspect of the present invention is a video device having a switch for detecting a user's operation amount in multiple stages , the switch body, a switch shaft mounted on the switch body so as to be reciprocally movable, and movement of the switch shaft A reflector that moves in conjunction with the light source, a light-emitting element that outputs light toward the reflector, a plurality of light-receiving elements that detect reflected light from the reflector and convert it into an electrical signal, and a movement of the switch shaft A table in which the amount and each light receiving element are associated with each other, and which light receiving element detects the reflected light based on a signal from each light receiving element, and refers to the table to determine the amount of movement corresponding to the light receiving element And a movement amount detection unit for calculating.

この装置では、ユーザからの操作量であるスイッチの移動量に連動して反射板が移動し、それに連動して複数の受光素子のうちで反射光を検知する受光素子も変わるため、スイッチの移動量と反射光を検知する受光素子とを一対一に対応させることができる。従って、どの受光素子が反射光を検知するかによってスイッチの移動量を求めることができる。また、各受光素子が反射光を検知したか否かが分かれば良いので、発光素子の発光量のばらつきに影響され難い。また、発光素子の発光量のばらつきに影響され難いため、発光量を一定に保つためのフィードバック制御等が必要ない。
さらに、この装置では、各受光素子と移動量とを対応させたテーブルを有しているので、各発光素子からの信号に基づいてどの受光素子が反射光を検知したのかが分かれば、テーブルを参照してその受光素子に対応する移動量を簡単に求めることができる。
In this device, the reflector moves in conjunction with the amount of movement of the switch, which is the amount of operation from the user, and the light receiving element that detects the reflected light among the plurality of light receiving elements changes accordingly. The amount and the light receiving element for detecting the reflected light can be made to correspond one-to-one. Therefore, the amount of movement of the switch can be determined depending on which light receiving element detects the reflected light. In addition, since it is only necessary to know whether each light receiving element has detected reflected light, it is difficult to be affected by variations in the light emission amount of the light emitting elements. In addition, since it is difficult to be influenced by variations in the light emission amount of the light emitting element, feedback control or the like for keeping the light emission amount constant is not necessary.
Furthermore, since this apparatus has a table in which each light receiving element is associated with the amount of movement, if the light receiving element detects the reflected light based on the signal from each light emitting element, the table is stored. It is possible to easily obtain the movement amount corresponding to the light receiving element with reference to it.

この映像装置によれば、簡易な構成及び制御によって、スイッチの操作量の検知の精度を向上させることができる。   According to this video apparatus, the accuracy of detection of the operation amount of the switch can be improved with a simple configuration and control.

The video device according to a second aspect of the present invention is the video device according to the first aspect , further comprising a guide member fixed to the switch shaft and having a guide groove. The reflecting plate includes a reflecting plate body having a reflecting surface, a first support member formed on the side surface of the reflecting plate body and rotatably supported by the switch body, and formed on the side surface of the reflecting plate body and along the guide groove. And a second support member supported by the guide member so as to be reciprocally movable. The guide member moves in conjunction with the movement of the switch shaft, and the second support member rotates about the first support member in conjunction with the movement of the guide member, whereby the reflector is rotated, and the reflector The light receiving element for detecting the reflected light changes in conjunction with the rotation of.

この装置では、スイッチ軸の移動に連動させて反射板を回転させることによって、反射光を検知する受光素子が変化し、スイッチ軸の移動量と反射光を検知する受光素子とを一対一に対応させることができる。スイッチ軸の移動に対して、反射板の回転量が大きくなるように構成すれば、限られた空間で反射方向の変化範囲を大きく採ることが可能であり、省スペースで精度の高い検出が可能である。
さらに、この装置では、ガイド部材、第１及び第２支持部材という簡易な構成によって、スイッチ軸の移動に連動して反射板が回転する構造を実現することができる。
In this device, by rotating the reflector in conjunction with the movement of the switch shaft, the light receiving element that detects the reflected light changes, and the amount of movement of the switch shaft and the light receiving element that detects the reflected light correspond one-to-one. Can be made. If the configuration is such that the amount of rotation of the reflector increases with respect to the movement of the switch shaft, it is possible to increase the range of change in the reflection direction in a limited space, and space-saving and highly accurate detection is possible. It is.
Further, in this apparatus, a structure in which the reflecting plate rotates in conjunction with the movement of the switch shaft can be realized with a simple configuration of the guide member and the first and second support members.

第３発明に係る映像装置は、第２発明に係る映像装置において、第１支持部材は、反射板本体の互いに対向する側面にそれぞれ同一軸上に設けられた第１及び第２突起部であることを特徴とする。
Video apparatus according to the third invention, in the imaging apparatus according to the second invention, the first support member is a first and second protrusion provided on the respective same axis on the side opposing the reflector body It is characterized by that.

反射板本体と第１及び第２突起部とを樹脂等で一体形成することができ、コストダウンを図ることができる。   The reflector main body and the first and second protrusions can be integrally formed with a resin or the like, and the cost can be reduced.

第４発明に係る映像装置は、第１発明に係る映像装置において、反射板は、スイッチ軸に対して回転不能に固定されており、スイッチ軸の移動に連動して平行移動する。そして、反射板の移動に連動して反射光を検知する受光素子が変化することを特徴とする。
A video device according to a fourth aspect of the present invention is the video device according to the first aspect of the invention, wherein the reflecting plate is fixed so as not to rotate with respect to the switch shaft, and moves in parallel with the movement of the switch shaft. And the light receiving element which detects reflected light changes in conjunction with the movement of a reflecting plate, It is characterized by the above-mentioned.

この装置では、反射板をスイッチ軸に対して回転不能に固定することによって、反射板は傾きを一定に保った状態で平行移動するが、反射板の位置によって反射光の反射位置が変わるので、スイッチ軸の移動に連動して反射光を検知する受光素子が変化する。反射板をスイッチ軸に対して回転不能に固定するという簡易な構成により、スイッチ軸の移動量と反射光を検知する受光素子とを一対一に対応させることができる。   In this device, by fixing the reflecting plate so as not to rotate with respect to the switch shaft, the reflecting plate moves in parallel with the inclination kept constant, but the reflection position of the reflected light changes depending on the position of the reflecting plate.

本発明よれば、簡易な構成によって、スイッチの操作量の検知の精度を向上させることができる。   According to the present invention, it is possible to improve the accuracy of detecting the operation amount of the switch with a simple configuration.

（１）第１実施形態
〔構造〕
図１は、第１実施形態に係るスイッチの一部切欠き側面図である。このスイッチは、映像装置等の電気機器に適用される。スイッチ本体１と、スイッチ軸２と、ガイド部材３と、反射板５と、発光素子９と、受光素子群１１とを備えている。 (1) First Embodiment [Structure]
FIG. 1 is a partially cutaway side view of a switch according to the first embodiment. This switch is applied to electrical equipment such as a video apparatus. A switch body 1, a switch shaft 2, a guide member 3, a reflecting plate 5, a light emitting element 9, and a light receiving element group 11 are provided.

スイッチ本体１は、略直方体形状の中空部材であり、上面に孔１ａを有している。スイッチ軸２は、棒状の部材であり、孔１ａを介してスイッチ本体１に挿入されている。スイッチ軸２の下部は、付勢部材としてのバネ１３を介してスイッチ本体１の底面に固定されている。バネ１３は、ユーザからの操作がない場合にスイッチ軸２が図１（ａ）に示す自由位置に位置するように付勢する。このときのスイッチ軸２の移動量Δｙ＝０とする。スイッチ軸２の上部にはボタン１２が固定されており、ボタン１２がユーザによって下方に押されると、スイッチ軸２はバネ１３の付勢力に抗して下方に移動する。   The switch body 1 is a hollow member having a substantially rectangular parallelepiped shape, and has a hole 1a on the upper surface. The switch shaft 2 is a rod-shaped member, and is inserted into the switch body 1 through the hole 1a. The lower part of the switch shaft 2 is fixed to the bottom surface of the switch body 1 via a spring 13 as an urging member. The spring 13 biases the switch shaft 2 so as to be positioned at the free position shown in FIG. 1A when there is no operation from the user. It is assumed that the movement amount Δy = 0 of the switch shaft 2 at this time. A button 12 is fixed to the upper part of the switch shaft 2, and when the button 12 is pressed downward by the user, the switch shaft 2 moves downward against the biasing force of the spring 13.

以下の説明では、スイッチ軸２の軸方向をｙ軸、ｙ軸に垂直な方向をｘ軸とし、ｙ軸を鉛直方向、ｘ軸を水平方向として説明する。但し、スイッチの配置の仕方によってはｙ軸及びｘ軸は互いに垂直な方向であれば任意の方向で良い。   In the following description, the axial direction of the switch shaft 2 will be described as the y-axis, the direction perpendicular to the y-axis as the x-axis, the y-axis as the vertical direction, and the x-axis as the horizontal direction. However, depending on how the switches are arranged, the y axis and the x axis may be in any direction as long as they are perpendicular to each other.

ガイド部材３は、スイッチ軸２の側面に固定され、スイッチ軸２の軸方向に垂直な方向（水平方向）に延び、反射板５の側方まで延びている。ガイド部材３は、水平方向に延びるガイド溝４を有しており、ガイド溝４には後述する反射板５の突起部８が支持されている。ここでは、ガイド部材３及びガイド溝４は、スイッチ軸２の軸方向に垂直な方向に延びる場合を説明するが、スイッチ軸２の軸方向に垂直な方向から傾いた方向に延びる場合であっても良い。
The guide member 3 is fixed to the side surface of the switch shaft 2, extends in a direction (horizontal direction) perpendicular to the axial direction of the switch shaft 2, and extends to the side of the reflecting plate 5 . The guide member 3 has a guide groove 4 extending in the horizontal direction, and a projection 8 of a reflection plate 5 described later is supported by the guide groove 4. Here, the case where the guide member 3 and the guide groove 4 extend in a direction perpendicular to the axial direction of the switch shaft 2 will be described. However, the guide member 3 and the guide groove 4 may extend in a direction inclined from the direction perpendicular to the axial direction of the switch shaft 2. Also good.

反射板５は、図１及び図２（ａ）に示すように、互いに対向する主面６ａ及び６ｂと、
主面６ａ及び６ｂに挟まれて互いに対向する側面６ｃ及び６ｄとを有する反射板本体６と、反射板本体６の互いに対向する側面６ｃ及び６ｄにそれぞれ同一軸上に設けられかつスイッチ本体１に回転自在に支持された一対の突起部７ａ及び７ｂと、反射板本体６の側面６ｃ及び６ｄに形成されかつガイド溝４に沿って往復移動可能にガイド部材３に支持された突起部８とを有している。主面６ａは、反射面であり、スイッチ軸２とは反対側に位置している。突起部７ａ及び７ｂは、それぞれ側面６ｃ及び６ｄから突出して同軸上に形成されている。突起部７ａ及び７ｂは、共通の軸線が主面６ａ及び６ｂの長辺を２等分するように形成されている。また、側面６ｃにおいて、突起部７ａから下方に離れた位置には、突起部８が側面６ｃから突出して形成されている。突起部８の長さは、突起部８が支持されるガイド部材３がスイッチ本体１の内壁面に接触せずに移動できるように、突起部７ａ及び７ｂの長さよりも短く形成されている。
As shown in FIGS. 1 and 2 (a), the reflecting plate 5 includes main surfaces 6a and 6b facing each other,
Reflector main body 6 having side surfaces 6c and 6d opposed to each other sandwiched between main surfaces 6a and 6b, and provided on the same axis on opposite side surfaces 6c and 6d of reflective plate main body 6 and provided on switch body 1 A pair of protrusions 7a and 7b supported rotatably, and a protrusion 8 formed on the side surfaces 6c and 6d of the reflector main body 6 and supported by the guide member 3 so as to be reciprocally movable along the guide groove 4. Have. The main surface 6a is a reflecting surface and is located on the side opposite to the switch shaft 2. The protrusions 7a and 7b are formed coaxially so as to protrude from the side surfaces 6c and 6d, respectively. The protrusions 7a and 7b are formed so that the common axis bisects the long sides of the main surfaces 6a and 6b. Further, on the side surface 6c, a protruding portion 8 is formed to protrude from the side surface 6c at a position away from the protruding portion 7a. The length of the protrusion 8 is shorter than the length of the protrusions 7 a and 7 b so that the guide member 3 on which the protrusion 8 is supported can move without contacting the inner wall surface of the switch body 1.

また、反射板５の側面６ｂ及び６ｃ側に位置するスイッチ本体１の内壁面には、図２（ｂ）に示すような軸受部１４がそれぞれ設けられている。軸受部１４には、軸受面１５が形成されており、各内壁面の軸受部１４の軸受面１５に突起部７ａ及び７ｂが回転自在に挿入される。軸受面１５の開放部１５ａは、突起部７ａ及び７ｂの直径よりも小さく形成されている。突起部７ａ及び７ｂを軸受面１５に挿入する際には、突起部７ａ及び７ｂで開放部１５ａを押し広げるようにして挿入する。突起部７ａ及び７ｂは、軸受面１５に支持されて同図（ａ）の矢印Ａに示すように回転する。
Moreover, the bearing part 14 as shown in FIG.2 (b) is provided in the inner wall surface of the switch main body 1 located in the side surfaces 6b and 6c side of the reflecting plate 5 , respectively. A bearing surface 15 is formed in the bearing portion 14, and the protrusions 7 a and 7 b are rotatably inserted into the bearing surface 15 of the bearing portion 14 on each inner wall surface. The opening 15a of the bearing surface 15 is formed smaller than the diameter of the protrusions 7a and 7b. When the protrusions 7a and 7b are inserted into the bearing surface 15, the protrusions 7a and 7b are inserted so as to widen the opening 15a. The protrusions 7a and 7b are supported by the bearing surface 15 and rotate as indicated by an arrow A in FIG.

また、突起部８は、ガイド部材３のガイド溝４に挿入されて支持される。図２（ｃ）は、突起部８をガイド部材３のガイド溝４に挿入して支持した様子を表す拡大図である。ガイド部材３はスイッチ軸２の側面に固定されているため、スイッチ軸２の上下移動に連動してガイド部材３も上下移動する。このとき、ガイド部材３によって突起部８も上下方向に移動するが、突起部７ａ及び７ｂが軸受部１４によって支持されているため突起部７ａ及び７ｂが軸受部１４内で回転する。これにより、突起部８は、ガイド部材３の上下運動によって上下方向に移動するとともにガイド溝４に沿って水平方向に移動（矢印Ｂ）することにより、突起部７ａ及び７ｂを中心に回転する。この結果、スイッチ軸２の上下移動によって、反射板５は突起部７ａ及び７ｂを中心に回転する（矢印Ｃ）。
The protrusion 8 is inserted into the guide groove 4 of the guide member 3 and supported. FIG. 2C is an enlarged view showing a state in which the protrusion 8 is inserted and supported in the guide groove 4 of the guide member 3. Since the guide member 3 is fixed to the side surface of the switch shaft 2, the guide member 3 also moves up and down in conjunction with the vertical movement of the switch shaft 2. At this time, the protrusion 8 is also moved in the vertical direction by the guide member 3. However, since the protrusions 7 a and 7 b are supported by the bearing 14, the protrusions 7 a and 7 b rotate within the bearing 14. As a result, the protrusion 8 is moved about the protrusions 7 a and 7 b by moving in the vertical direction by the vertical movement of the guide member 3 and moving in the horizontal direction along the guide groove 4 (arrow B). As a result, as the switch shaft 2 moves up and down, the reflector 5 rotates about the protrusions 7a and 7b (arrow C).

発光素子９は、反射板５の主面６ａ（反射面）に対向するスイッチ本体１の内壁面に形成された固定部１０に固定されている。発光素子９は、指向性の高い半導体レーザが好ましい。発光素子９から出射された光は、主面６ａの中央に入射するように調整されている。受光素子群１１は、複数の受光素子１１ａ〜１１ｅから構成されており、各受光素子１１ａ〜１１ｅは１列に配置されている。各受光素子１１ａ〜１１ｅは、スイッチ軸２の上下移動によって反射板５が回転する範囲で反射光を受光できる位置に配置されている。各受光素子１１ａ〜１１ｅは、スイッチ軸２の移動量Δｙに対して何れかの受光素子１１ａ〜１１ｅに反射光が入射されるように、十分接近させて配置することが好ましい。受光素子の数及びそれらの配列間隔は、反射光の方向の変動範囲に応じて適宜選択すれば良い。
The light emitting element 9 is fixed to a fixing portion 10 formed on the inner wall surface of the switch body 1 facing the main surface 6a (reflection surface) of the reflection plate 5 . The light emitting element 9 is preferably a semiconductor laser with high directivity. The light emitted from the light emitting element 9 is adjusted to enter the center of the main surface 6a. The light receiving element group 11 includes a plurality of light receiving elements 11a to 11e, and the light receiving elements 11a to 11e are arranged in one row. Each of the light receiving elements 11 a to 11 e is disposed at a position where the reflected light can be received within a range in which the reflecting plate 5 rotates by the vertical movement of the switch shaft 2. Each of the light receiving elements 11a to 11e is preferably arranged sufficiently close to the amount of movement Δy of the switch shaft 2 so that the reflected light is incident on any of the light receiving elements 11a to 11e. The number of light receiving elements and their arrangement interval may be appropriately selected according to the fluctuation range of the direction of the reflected light.

図３は、受光素子群１１による反射光の検知からスイッチ軸２の移動量を算出するための回路の構成例である。受光素子群１１の各受光素子１１ａ〜１１ｅは、互いに並列に接続されており、それぞれ、カソード側が高電位側ＶＣＣに接続されており、アノード側が抵抗器Ｒを介して基準電位ＶＳＳ（例えば接地電位）に接続されている。各受光素子１１ａ〜１１ｅのアノード側は、それぞれ比較器１６ａ〜１６ｅ（比較部１６）に接続されている。比較器１６ａ〜１６ｅは、各受光素子１１ａ〜１１ｅでの反射光の受光を検知するために所定の閾値が設定されている。比較器１６ａ〜１６ｅは、入力電位と閾値とを比較し、各受光素子１１ａ〜１１ｅからの電気的な信号を閾値と比較し、例えば、信号が閾値より大きければＬｏｗを出力し、信号が閾値未満であればＨｉｇｈを出力する。   FIG. 3 is a configuration example of a circuit for calculating the amount of movement of the switch shaft 2 from detection of reflected light by the light receiving element group 11. The light receiving elements 11a to 11e of the light receiving element group 11 are connected in parallel to each other, the cathode side is connected to the high potential side VCC, and the anode side is connected to the reference potential VSS (for example, ground potential) via the resistor R. )It is connected to the. The anode sides of the light receiving elements 11a to 11e are connected to the comparators 16a to 16e (comparison unit 16), respectively. In the comparators 16a to 16e, a predetermined threshold is set in order to detect the reception of the reflected light at each of the light receiving elements 11a to 11e. The comparators 16a to 16e compare the input potential with the threshold value, compare the electrical signal from each of the light receiving elements 11a to 11e with the threshold value, for example, output Low when the signal is larger than the threshold value, and the signal is the threshold value. If it is less, High is output.

移動量算出部１７は、比較器１６ａ〜１６ｅからの信号に基づいて反射光を受光した受光素子を決定し、テーブル１８を参照し、該受光素子に対応する移動量Δｙを算出する。   The movement amount calculation unit 17 determines the light receiving element that has received the reflected light based on the signals from the comparators 16a to 16e, refers to the table 18, and calculates the movement amount Δy corresponding to the light receiving element.

なお、各受光素子１１ａ〜１１ｅそれぞれからの電気信号を、比較器１６ａ〜１６ｅに入力する代わりに、直接または増幅（昇圧、降圧）して移動量算出部１７に入力し、移動量算出部１７において各受光素子１１ａ〜１１ｅからの信号を比較して反射光を受光した受光素子を決定するようにしても良い。   In addition, instead of inputting the electrical signals from the respective light receiving elements 11a to 11e to the comparators 16a to 16e, they are directly or amplified (boosted and stepped down) and input to the moving amount calculating unit 17, and the moving amount calculating unit 17 The light receiving elements that receive the reflected light may be determined by comparing signals from the light receiving elements 11a to 11e.

テーブル１８は、図４に示すように、反射光を受光する各受光素子１１ａ〜１１ｅとスイッチ軸２の移動量Δｙとを対応付けて保持している。テーブル１８は、スイッチ軸２の移動量Δｙと反射光を受光する各受光素子１１ａ〜１１ｅとの対応を実験により求め、予
め保持しておく。 As shown in FIG. 4, the table 18 holds the respective light receiving elements 11 a to 11 e that receive reflected light and the movement amount Δy of the switch shaft 2 in association with each other. The table 18 obtains the correspondence between the movement amount Δy of the switch shaft 2 and each of the light receiving elements 11a to 11e that receives the reflected light by experiment, and holds it in advance.

ユーザがボタン１２を操作していない状態では、図１（ａ）に示すように、ユーザの操作量であるスイッチ軸２の移動量はΔｙ＝０であり、反射板５のｙ軸からの傾きθ＝θ０である。ここでは、θ０を４５°とするが、４５°以外の角度であっても良い。発光素子９から出射した光は、反射板５の主面６ａで反射されて反射位置の真下にある受光素子１１ａに入射する。このとき、図３において、受光素子１１ａのみ導通し、受光素子１１ａのアノード側にのみ電圧が発生する。従って、比較器１６ａのみがＬｏｗを出力し、比較器１６ｂ〜１６ｅはＨｉｇｈを出力する。移動量算出部１７は、比較器１６ａ〜１６ｅからの信号に基づいて受光素子１１ａが反射光を検知したことを決定し、テーブル１７を参照し、受光素子１１ａに対応する移動量Δｙ＝０を出力する。
[Function and effect]
In a state where the user is not operating the button 12, as shown in FIG. 1A, the movement amount of the switch shaft 2, which is the operation amount of the user, is Δy = 0, and the inclination of the reflecting plate 5 from the y axis. θ = θ0. Here, θ0 is 45 °, but it may be an angle other than 45 °. The light emitted from the light emitting element 9 is reflected by the main surface 6a of the reflecting plate 5 and enters the light receiving element 11a directly below the reflecting position. At this time, in FIG. 3, only the light receiving element 11a is conducted, and a voltage is generated only on the anode side of the light receiving element 11a. Therefore, only the comparator 16a outputs Low, and the comparators 16b to 16e output High. The movement amount calculation unit 17 determines that the light receiving element 11a has detected the reflected light based on the signals from the comparators 16a to 16e, refers to the table 17, and sets the movement amount Δy = 0 corresponding to the light receiving element 11a. Output.

ユーザがボタン１２を下方に押すと、図１（ｂ）に示すように、スイッチ軸２及びガイ
ド部材３が連動して下方に移動する。これにより、反射部３の突起部８は、ガイド部材３に連動して下方に移動するとともにガイド溝４内をスイッチ軸２から離れる方向に移動し、突起部７ａ及び７ｂを中心に紙面に向かって時計回り（図２（ａ）矢印Ａ）に回転し、反射板５のｙ軸からの傾きθはθ１（＜θ０）に減少する。この結果、発光素子９から出射された光の反射角も減少し、反射光が受光素子１１ｂに入射する。このとき、図３において、受光素子１１ｂのみ導通し、受光素子１１ｂのアノード側にのみ電圧が発生する。従って、比較器１６ｂのみがＬｏｗを出力する。移動量算出部１７は、比較器１６ａ〜１６ｅからの信号に基づいて受光素子１１ｂが反射光を検知したことを決定し、テーブル１７を参照し、受光素子１１ｂに対応する移動量Δｙ＝Δｙ１を出力する。
When the user presses the button 12 downward, as shown in FIG. 1B, the switch shaft 2 and the guide member 3 move downward in conjunction with each other. As a result, the protrusion 8 of the reflecting portion 3 moves downward in conjunction with the guide member 3 and moves in the direction away from the switch shaft 2 in the guide groove 4, and toward the paper surface with the protrusions 7a and 7b as the center. Rotate clockwise (arrow A in FIG. 2A), and the inclination θ of the reflecting plate 5 from the y-axis decreases to θ1 (<θ0). As a result, the reflection angle of the light emitted from the light emitting element 9 also decreases, and the reflected light enters the light receiving element 11b. At this time, in FIG. 3, only the light receiving element 11b is conducted, and a voltage is generated only on the anode side of the light receiving element 11b. Therefore, only the comparator 16b outputs Low. The movement amount calculation unit 17 determines that the light receiving element 11b has detected the reflected light based on the signals from the comparators 16a to 16e, refers to the table 17, and sets the movement amount Δy = Δy1 corresponding to the light receiving element 11b. Output.

ユーザがボタン１２を押す量（操作量）の増大とともに、上記同様にして反射板５のｙ軸からの傾きが減少し、反射光は受光素子１１ｃ、１１ｄ、１１ｅに順番に入射する。受光素子１１ｃ、１１ｄ、１１ｅでの反射光の検知に従い、移動量算出部１７はテーブル１８を参照することによりそれぞれ移動量Δｙ＝Δｙ２、Δｙ３、Δｙ４を出力する。
As the amount by which the user presses the button 12 (operation amount) increases, the inclination of the reflecting plate 5 from the y-axis decreases in the same manner as described above, and the reflected light sequentially enters the light receiving elements 11c, 11d, and 11e. As the reflected light is detected by the light receiving elements 11c, 11d, and 11e, the movement amount calculation unit 17 refers to the table 18 and outputs movement amounts Δy = Δy2, Δy3, and Δy4, respectively.

本実施形態に係るスイッチによれば、スイッチ軸２の移動に連動して反射板５が回転することにより、反射光を検知する受光素子１１ａ〜１１ｅが順次変化するため、反射光を検知する受光素子１１ａ〜１１ｅとスイッチ軸２の移動量Δｙとを一対一に対応させることができる。従来の構成のように、反射光の強度の大きさに応じてスイッチ軸２の移動量Δｙを求めようとすると、発光素子９の個体間でのばらつきに影響され易い。一方、本実施形態では、スイッチ軸２の移動量Δｙに物理的に対応する位置に各受光素子１１ａ〜１１ｅを配置し、どの受光素子が反射光を検知したかに基づいて移動量Δｙを決定するので、各受光素子１１ａ〜１１ｅでは検知したか否かのみの判断が行えれば良く、発光素子９の個体間でのばらつきに影響されにくい。
According to the switch according to the present embodiment, the light receiving elements 11a to 11e that detect the reflected light change sequentially as the reflecting plate 5 rotates in conjunction with the movement of the switch shaft 2, and thus the light receiving that detects the reflected light. The elements 11a to 11e and the movement amount Δy of the switch shaft 2 can be made to correspond one-to-one. When the movement amount Δy of the switch shaft 2 is determined according to the intensity of the reflected light as in the conventional configuration, it is easily affected by the variation among the individual light emitting elements 9. On the other hand, in the present embodiment, the light receiving elements 11a to 11e are arranged at positions physically corresponding to the movement amount Δy of the switch shaft 2, and the movement amount Δy is determined based on which light receiving element detects the reflected light. Therefore, it is only necessary to determine whether or not each of the light receiving elements 11a to 11e has detected, and it is difficult to be influenced by the variation among the individual light emitting elements 9.

また、発光素子９の発光量のばらつきに影響され難いため、発光量を一定に保つためのフィードバック制御等が必要ない。また、各受光素子１１ａ〜１１ｅと移動量Δｙとを対応させたテーブル１８を有しているので、各受光素子１１ａ〜１１ｅからの信号に基づいてどの受光素子が反射光を検知したのかが分かれば、テーブル１８を参照してその受光素子に対応する移動量Δｙを簡単に求めることができる。   Further, since it is difficult to be affected by variations in the light emission amount of the light emitting element 9, feedback control or the like for keeping the light emission amount constant is not necessary. Further, since the table 18 in which each of the light receiving elements 11a to 11e is associated with the movement amount Δy is provided, which light receiving element detects the reflected light based on the signal from each of the light receiving elements 11a to 11e. For example, the movement amount Δy corresponding to the light receiving element can be easily obtained by referring to the table 18.

このスイッチを映像装置に用いれば、簡易な構成によって、スイッチの操作量の検知の精度を向上させることができる。   If this switch is used in a video apparatus, the detection accuracy of the operation amount of the switch can be improved with a simple configuration.

上記スイッチを映像装置に用いる場合、スイッチによって実行される機能が例えば音量アップ又はダウン、チャンネルアップ又はダウン、早送り又は巻き戻し、画面の輝度調整
である場合には、スイッチ軸２の移動量Δｙを検知し、それに基づいて各機能の実行をよりきめ細やかに制御することが可能になる。具体的には、ユーザからの操作量がΔｙ＝Δｙ１である場合には音量アップ又はダウンのスピードをｖ１とし、Δｙ＝Δｙ２でｖ２（＞ｖ１）、Δｙ＝Δｙ３でｖ３（＞ｖ２）、Δｙ＝Δｙ４でｖ４（＞ｖ３）というように、操作量Δｙの増加に従い音量アップ又はダウンのスピードを増加させるようにしても良い。チャンネルアップ又はダウン等についても同様である。 When the switch is used in a video apparatus, when the function executed by the switch is, for example, volume up or down, channel up or down, fast forward or rewind, screen brightness adjustment, the movement amount Δy of the switch shaft 2 is set to It is possible to detect and control the execution of each function more finely based on it. Specifically, when the operation amount from the user is Δy = Δy1, the volume up / down speed is set to v1, Δy = Δy2 is v2 (> v1), Δy = Δy3 is v3 (> v2), Δy = V4 (> v3) at Δy4, the volume up / down speed may be increased as the operation amount Δy increases. The same applies to channel up or down.

また、ユーザの操作量Δｙによって機能実行の感度を変化させたい場合には、Δｙ＝Δｙ１〜Δｙ３では機能実行のスピードｖ１，ｖ２，ｖ３を緩やかに増加又は変化なしとし、Δｙ＝Δｙ４で機能実行のスピードｖ４をｖ３から大幅に増加させるようにしても良い。   When it is desired to change the function execution sensitivity according to the user operation amount Δy, the function execution speeds v1, v2, v3 are gradually increased or unchanged at Δy = Δy1 to Δy3, and the function execution is performed at Δy = Δy4. The speed v4 may be significantly increased from v3.

また、移動量Δｙの検出精度を向上させる場合（検出感度を向上させる場合）には、検出精度を向上させたい移動量Δｙの範囲で受光素子の密度を高くすればよい。例えば、移動量Δｙが小さい範囲（０〜Δｙ２）で検出精度を向上させる場合には、図１に示す受光素子群１１においてスイッチ軸２に近い側にある受光素子の密度を高くすれば良い。   When the detection accuracy of the movement amount Δy is improved (when the detection sensitivity is improved), the density of the light receiving elements may be increased within the range of the movement amount Δy where the detection accuracy is desired to be improved. For example, when the detection accuracy is improved in a range where the movement amount Δy is small (0 to Δy2), the density of the light receiving elements on the side closer to the switch shaft 2 in the light receiving element group 11 shown in FIG.

なお、本実施形態では、反射板５の回転中心である突起部７ａ及び７ｂを主面６ａ及び６ｂの長辺を二等分する位置に、作用点である突起部８を回転中心よりも下方に配置したが、突起部８を回転中心よりも上方に配置しても良い。この場合、スイッチ軸２の移動に伴う反射板５の回転方向が逆になり（反時計回り）、反射光が移動する方向も逆になるので、受光素子群１１を回転中心の位置からスイッチ軸２に近い側に配置する必要がある。
In the present embodiment, the protrusions 7a and 7b that are the rotation center of the reflecting plate 5 are positioned so that the long sides of the main surfaces 6a and 6b are equally divided, and the protrusion 8 that is the action point is located below the rotation center. However, the protrusion 8 may be disposed above the center of rotation. In this case, the rotation direction of the reflecting plate 5 accompanying the movement of the switch shaft 2 is reversed (counterclockwise), and the direction in which the reflected light moves is also reversed, so that the light receiving element group 11 is moved from the position of the rotation center to the switch shaft. It is necessary to arrange on the side close to 2.

また、回転中心（突起部７ａ及び７ｂ）と作用点（突起部８）との間の距離を大きくするほど、スイッチ軸２の移動量Δｙに対する反射板５の傾きの変化も大きくなり、反射光の方向が変化する範囲も大きくなる。従って、スイッチ軸２の移動量が微小である場合に移動量Δｙの検出精度を向上させるには、回転中心と作用点との距離を大きくして反射方向の変化範囲を大きくすることが有効である。
Further, as the distance between the rotation center (protrusions 7a and 7b) and the action point (protrusion 8) increases, the change in the inclination of the reflecting plate 5 with respect to the movement amount Δy of the switch shaft 2 also increases. The range in which the direction of changes also increases. Therefore, in order to improve the detection accuracy of the movement amount Δy when the movement amount of the switch shaft 2 is very small, it is effective to increase the range of change in the reflection direction by increasing the distance between the rotation center and the action point. is there.

また、回転中心（突起部７ａ及び７ｂ）は、反射板５の主面６ａ及び６ｂの長辺を二等分する位置にある必要はなく、他の位置にあっても良い。例えば、回転中心（突起部７ａ及び７ｂ）を一端部付近に設け、作用点（突起部８）を他端部付近に設ければ、反射板５の回転半径を大きくとることができる。
Further, the rotation center (projections 7a and 7b) does not need to be at a position where the long sides of the main surfaces 6a and 6b of the reflecting plate 5 are equally divided, and may be at another position. For example, if the center of rotation (projections 7a and 7b) is provided near one end and the point of action (projection 8) is provided near the other end, the radius of rotation of the reflector 5 can be increased.

また、上記では、図３に示すように、各受光素子１１ａ〜１１ｅそれぞれからの電気信号を個々に比較したが、比較回路１６の代わりに、各受光素子１１ａ〜１１ｅそれぞれからの電気信号を直接または増幅（昇圧、降圧）して移動量算出部１７に入力し、移動量算出部１７においてどの受光素子１１ａ〜１１ｅからの電気信号が最大かを判断し、信号が最大である受光素子を「反射光を検知した受光素子」として決定しても良い。このようにすれば、発光素子９がＬＥＤ等であり隣接する受光素子で反射光を受光してしまう場合にも、受光量が最大の受光素子に基づいて移動量Δｙを求めることができる。   In the above description, as shown in FIG. 3, the electric signals from the respective light receiving elements 11a to 11e are individually compared. However, instead of the comparison circuit 16, the electric signals from the respective light receiving elements 11a to 11e are directly compared. Alternatively, the signal is amplified (boosted, stepped down) and input to the movement amount calculation unit 17, and the movement amount calculation unit 17 determines which light receiving element 11 a to 11 e has the maximum electric signal. You may determine as a light receiving element which detected reflected light. In this way, even when the light emitting element 9 is an LED or the like and the adjacent light receiving element receives the reflected light, the movement amount Δy can be obtained based on the light receiving element having the maximum light receiving amount.

（２）第２実施形態
〔構造〕
図５は、第２実施形態に係るスイッチの一部切欠き断面図である。本実施形態が上記第１実施形態と異なる点は、反射板５が傾きを一定に保った状態で、スイッチ軸２の移動に連動してスイッチ軸２と同じ方向に平行移動する点である。
(2) Second Embodiment [Structure]
FIG. 5 is a partially cutaway sectional view of a switch according to the second embodiment. The present embodiment is different from the first embodiment in that the reflector 5 is translated in the same direction as the switch shaft 2 in conjunction with the movement of the switch shaft 2 with the inclination kept constant.

本実施形態に係る反射板５は、図６に示すように、互いに対向する主面６ａ及び６ｂと、主面６ａ及び６ｂに挟まれて互いに対向する側面６ｃ及び６ｄとを備えている。第１実施形態と同様に、スイッチ軸２と反対側に配置された主面６ａが反射面である。主面６ｂの中央付近には棒状の固定部材３ａの一端が固定されており、固定部材３ａの他端がスイッチ軸２に固定されている。即ち、反射板５は、固定部材３ａによってスイッチ軸２に対して回転不能に固定されている。固定の方法は、反射板５がスイッチ軸２に対して回転不能に固定される方法であれば、他の方法であっても良い。
As shown in FIG. 6, the reflecting plate 5 according to the present embodiment includes main surfaces 6a and 6b facing each other, and side surfaces 6c and 6d facing each other sandwiched between the main surfaces 6a and 6b. Similar to the first embodiment, the main surface 6a disposed on the opposite side of the switch shaft 2 is a reflecting surface. One end of a rod-shaped fixing member 3a is fixed near the center of the main surface 6b, and the other end of the fixing member 3a is fixed to the switch shaft 2. That is, the reflecting plate 5 is fixed to the switch shaft 2 so as not to rotate by the fixing member 3a. The fixing method may be other methods as long as the reflecting plate 5 is fixed to the switch shaft 2 so as not to rotate.

受光素子群１１での受光に基づいて移動量Δｙを算出する回路の構成は、図３及び図４と同様である。   The configuration of the circuit that calculates the movement amount Δy based on the light received by the light receiving element group 11 is the same as in FIGS. 3 and 4.

〔作用効果〕
ユーザがボタン１２を操作していない状態では、図５（ａ）に示すように、スイッチ軸２の移動量Δｙ＝０であり、反射板５のｙ軸からの傾きはθ＝θ０（例えば４５°）である。従って、発光素子９から出射した光は、反射板５の主面６ａで反射されて反射位置の真下にある受光素子１１ａに入射する。このとき、受光素子１１ａのみが導通し、比較器１６ａのみからＬｏｗが出力され、他の比較器からはＨｉｇｈが出力される。移動量算出部１７は、比較器１６ａ〜１６ｅからの信号に基づいて受光素子１１ａが反射光を検知したことを決定し、テーブル１７を参照し、受光素子１１ａに対応する移動量Δｙ＝０を出力する。
[Function and effect]
In a state where the user does not operate the button 12, as shown in FIG. 5A, the movement amount Δy = 0 of the switch shaft 2 and the inclination of the reflecting plate 5 from the y axis is θ = θ0 (for example, 45). °). Therefore, the light emitted from the light emitting element 9 is reflected by the main surface 6a of the reflecting plate 5 and enters the light receiving element 11a immediately below the reflection position. At this time, only the light receiving element 11a is conducted, Low is output only from the comparator 16a, and High is output from the other comparators. The movement amount calculation unit 17 determines that the light receiving element 11a has detected the reflected light based on the signals from the comparators 16a to 16e, refers to the table 17, and sets the movement amount Δy = 0 corresponding to the light receiving element 11a. Output.

ユーザがボタン１２を下方に押すと、図５（ｂ）に示すように、スイッチ軸２が下方に移動するとともに、反射板５が傾きをθ＝θ０に保った状態で下方に平行移動する。これにより、発光素子９からの光の反射位置が同図（ａ）の場合よりも外側上方にずれて、反射光は受光素子１１ｂに入射される。このとき、受光素子１１ｂのみが導通し、比較器１６ｂのみがＬｏｗを出力する。移動量算出部１７は、比較器１６ａ〜１６ｅからの信号に基づいて受光素子１１ｂで反射光を検知したことを決定し、テーブル１８を参照し、受光素子１１ｂに対応するスイッチ軸２の移動量Δｙ＝Δｙ１を出力する。
When the user presses the button 12 downward, as shown in FIG. 5B, the switch shaft 2 moves downward, and the reflecting plate 5 translates downward with the inclination maintained at θ = θ0. As a result, the reflection position of the light from the light emitting element 9 is shifted outward and upward as compared with the case of FIG. 9A, and the reflected light enters the light receiving element 11b. At this time, only the light receiving element 11b conducts and only the comparator 16b outputs Low. The movement amount calculating unit 17 determines that the reflected light is detected by the light receiving element 11b based on the signals from the comparators 16a to 16e, refers to the table 18, and moves the switch shaft 2 corresponding to the light receiving element 11b. Δy = Δy1 is output.

ユーザがボタン１２を押す量（操作量）の増大とともに、上記同様にして反射板５が下方に平行移動し、光の反射位置が外側上方に向かって移動し、反射光は受光素子１１ｃ、１１ｄ、１１ｅに順番に入射されるようになる。受光素子１１ｃ、１１ｄ、１１ｅでの反射光の受光に従い、移動量算出部１７はテーブル１８を参照することによりそれぞれ移動量Δｙ＝Δｙ２、Δｙ３、Δｙ４を出力する。
As the amount by which the user presses the button 12 (the amount of operation) increases, the reflecting plate 5 translates downward in the same manner as described above, the light reflection position moves outward and upward, and the reflected light is received by the light receiving elements 11c and 11d. , 11e in order. As the reflected light is received by the light receiving elements 11c, 11d, and 11e, the movement amount calculation unit 17 refers to the table 18 and outputs movement amounts Δy = Δy2, Δy3, and Δy4, respectively.

本実施形態に係るスイッチでは、スイッチ軸２の移動に連動して反射板５を回転させる機構の代わりに、反射板５をスイッチ軸２に回転不能に固定して平行移動させる構成としたことにより、より簡易な構成で、上記第１実施形態と同様の作用効果を奏する。 In the switch according to the present embodiment, instead of the mechanism for rotating the reflecting plate 5 in conjunction with the movement of the switch shaft 2, the reflecting plate 5 is fixed to the switch shaft 2 so as not to rotate and is translated. With a simpler configuration, the same operational effects as those of the first embodiment can be obtained.
