Description

この発明は、照明器具の調光レベルを制御するための調光器と、同調光器を用いた調光システムに関する。 The present invention relates to a dimmer for controlling the dimming level of a luminaire and a dimming system using a tuning dimmer.

オフィスや商業ビルなど業務用途の主照明にあっては、明るい外光が入射する日中であっても照明を消灯することは不体裁であり、節電のために間引き点灯(照明を部分的に消灯)することも受け入れ難い。
このような使途の主照明として高周波点灯型蛍光灯器具(インバータ蛍光灯器具)が用いられる場合、PWM信号(パルス幅変調信号)等の調光信号制御により、照明器具の発光出力を適宜抑制して適切な照度を確保するとともに、照明器具の消費する電力を抑制する調光システムが存在する。
近年、LED(発光ダイオード)を光源とする照明器具の需要増加に伴い、PWM信号等の調光制御信号により当該照明器具の調光レベルを制御することが容易となり、省エネに対する需要の増加も相俟って、上記PWM信号方式の調光器が各種提案されている。従来のこの種の調光器は、オフィスビル等の広い空間に施設された多数の照明器具の調光レベルを制御するための用途に用いられており、そのため比較的大形の構造をしたものが一般的であった。
For main lighting for business use such as offices and commercial buildings, it is unreasonable to turn off the lighting even during the daytime when bright outside light is incident, and thinning out lighting to save power (partially lighting) It is also unacceptable to turn off the lights.
When a high-frequency lighting type fluorescent lamp fixture (inverter fluorescent lamp fixture) is used as the main lighting for such a purpose, the light emission output of the lighting fixture is appropriately suppressed by controlling a dimming signal such as a PWM signal (pulse width modulation signal). There is a dimming system that secures an appropriate illuminance and suppresses the power consumed by the lighting equipment.
In recent years, with the increase in demand for lighting fixtures that use LEDs (light emitting diodes) as light sources, it has become easier to control the dimming level of the lighting fixtures with dimming control signals such as PWM signals, and the demand for energy saving has also increased. In addition, various types of PWM signal type dimmers have been proposed. Conventional dimmers of this type are used to control the dimming level of a large number of lighting fixtures installed in a large space such as an office building, and therefore have a relatively large structure. Was common.

これに対し、特許文献1に開示された調光器は、JISで規格化された配線器具用の取付枠(JIS C 8375)と略等しい大きさに形成された取付枠に3個まで取着可能な単位寸法の2個分の大きさ(2個モジュール寸法)に形成されたケース(同文献1の段落「0026」参照)に収められており、家庭用の照明器具を調光する用途に好適な寸法構造となっている。 On the other hand, up to three dimmers disclosed in Patent Document 1 are attached to a mounting frame formed to have a size substantially equal to that of a mounting frame (JIS C 8375) for wiring equipment standardized by JIS. It is housed in a case (see paragraph "0026" of the same document 1) formed in the size of two possible unit dimensions (two module dimensions), and is used for dimming household lighting equipment. It has a suitable dimensional structure.

しかし、特許文献1に開示された調光器は、単一の調光制御信号を出力できるのみであり、共通に制御可能な同一系統に含まれる照明器具しか調光できない。したがって、複数系統の照明器具を別々に調光するには、当該系統の数に応じた個数の調光器を用意する必要があり、それら複数の調光器を設置するためにスペースを広く確保する必要が生じるという課題があった。 However, the dimmer disclosed in Patent Document 1 can only output a single dimming control signal, and can dimm only lighting fixtures included in the same system that can be controlled in common. Therefore, in order to dimm the lighting fixtures of multiple systems separately, it is necessary to prepare the number of dimmers according to the number of the systems, and a large space is secured for installing the plurality of dimmers. There was a problem that it was necessary to do it.

また、複数系統に区分けされた各照明器具であっても、同じ調光レベル(例えば、同じ明るさ)に制御したいこともある。例えば、各系統の照明空間がともに同じ用途に使われる場合(例えば、ともにオフィス空間である場合)には、一般に同じ調光レベルに調整される。しかし、別系統に区分けされた照明器具には、それぞれ別個の調光器が割り当てられているため、同じ調光レベルに制御するには、各調光器を同じ調整量とするための細かな操作が必要となり困難性を伴うという課題があった。 In addition, even if each luminaire is divided into a plurality of systems, it may be desired to control the same dimming level (for example, the same brightness). For example, when the lighting spaces of each system are used for the same purpose (for example, when both are office spaces), they are generally adjusted to the same dimming level. However, since each luminaire divided into different systems is assigned a separate dimmer, in order to control to the same dimming level, it is necessary to make each dimmer the same amount of adjustment. There was a problem that operation was required and it was difficult.

特許第5244033号公報Japanese Patent No. 5244033

本発明は上述した事情に鑑みてなされたもので、家庭用の照明器具を調光する用途にも好適な大きさであって、2系統の照明器具に対して調光レベルを別々に制御することができ、しかも各系統の照明器具を極めて容易な操作で同じ調光レベルに制御することもできる調光器の提供を目的とする。 The present invention has been made in view of the above circumstances, has a size suitable for dimming household lighting fixtures, and controls dimming levels separately for two systems of lighting fixtures. It is an object of the present invention to provide a dimmer that can control the lighting fixtures of each system to the same dimming level with extremely easy operation.

JISで規格化された配線器具の取付枠に収まる大きさに形成され、第1,第2の各調光制御回路及び電源回路を内部に収納するとともに、第1,第2の調光操作手段が組み込まれたケース本体と、を備え、
第1,第2の各調光操作手段は、2個の可変抵抗を同軸状に設けた2本の回転軸をもって各々操作する構成の2軸2連型可変抵抗器と、この2軸2連型可変抵抗器の一方の回転軸に装着した第1の操作つまみと、2軸2連型可変抵抗器の他方の回転軸に装着され第1の操作つまみと軸方向に並べて配置した第2の操作つまみと、を含む構成としたことを特徴とする。
In order to achieve the above object, the dimmer of the present invention
The first dimming operating means for adjusting the dimming level of the luminaire,
A first dimming control circuit that generates a dimming control signal that controls the dimming level of the luminaire according to the operation of the first dimming operating means,
A second dimming operating means for adjusting the dimming level of the luminaire,
A second dimming control circuit that generates a dimming control signal that controls the dimming level of the luminaire according to the operation of the second dimming operating means,
A power supply circuit that converts the power supplied from the commercial power supply into power for operating the first and second dimming control circuits and outputs the power to each dimming control circuit.
It is formed in a size that fits in the mounting frame of the wiring equipment standardized by JIS, and houses the first and second dimming control circuits and the power supply circuit inside, and the first and second dimming operation means. With a built-in case body,
The first and second dimming operating means are a two-axis dual variable resistor having a configuration in which two variable resistors are coaxially provided and operated by two rotating shafts, and the two-axis dual resistors. A first operation knob mounted on one rotation shaft of the type variable resistor and a second operation knob mounted on the other rotation shaft of the dual-axis dual type variable resistor and arranged side by side with the first operation knob. It is characterized by having a configuration including an operation knob.

上述したように、本発明の調光器は、ケース本体がJISで規格化された配線器具の取付枠に収まる大きさに形成されているため、小形で家庭用の照明器具を調光する用途にも好適である。 As described above, the dimmer of the present invention is used for dimming small household lighting fixtures because the case body is formed in a size that fits in the mounting frame of the wiring fixture standardized by JIS. It is also suitable for.

しかも、第1,第2の各調光制御回路からそれぞれ調光制御信号が出力されるので、各調光制御信号により2系統の照明器具に対して調光レベルを別々に制御することができる。これら第1,第2の各調光制御回路は、共通の電源回路から電力を得て動作する。このように電源回路を共通化することで小形化を実現することができる。 Moreover, since the dimming control signals are output from the first and second dimming control circuits, the dimming level can be controlled separately for the two lighting fixtures by each dimming control signal. .. Each of the first and second dimming control circuits operates by obtaining power from a common power supply circuit. By standardizing the power supply circuit in this way, miniaturization can be realized.

さらに、2軸2連型可変抵抗器に内蔵された2個の可変抵抗を、第1,第2の各操作つまみによってそれぞれ操作する構成とし、かつこれら第1,第2の各操作つまみを軸方向に並べて配置することで、各操作つまみを一緒に回転操作するだけの極めて容易な操作をもって、第1,第2の各調光制御回路から同じ調光制御信号が出力され、各系統の照明器具を同じ調光レベルに制御することが可能となる。
もちろん、各操作つまみを別々に回転操作して、各系統の照明器具をそれぞれ異なった調光レベルに制御することもできる。
Further, the two variable resistors built in the two-axis dual variable resistor are operated by the first and second operation knobs, respectively, and the first and second operation knobs are used as axes. By arranging them side by side in the direction, the same dimming control signal is output from each of the first and second dimming control circuits with extremely easy operation of rotating each operation knob together, and the lighting of each system is illuminated. It is possible to control the equipment to the same dimming level.
Of course, it is also possible to rotate each operation knob separately to control the lighting fixtures of each system to different dimming levels.

また、本発明は、第1,第2の各操作つまみは、一方の操作つまみに対し座金を介して他方の操作つまみを押し当てることで相互間の位置決めがされる構成である調光器において、
第1,第2の各操作つまみの対向部位に、一方の操作つまみには凹部を形成し、他方の操作つまみには凸部を形成するとともに、
第1,第2の各操作つまみの対向部位の間に座金が配置されているときは、凹部への凸部の入り込みが当該座金に阻まれ、
第1,第2の各操作つまみの対向部位の間に座金が配置されていないときには、第1,第2の各操作つまみを相対的に押圧回転させたとき、凹部へ凸部が入り込む構成とすることが好ましい。
Further, the present invention relates to a dimmer in which the first and second operation knobs are positioned between each other by pressing the other operation knob against one operation knob via a washer. ,
A concave portion is formed on one of the operation knobs and a convex portion is formed on the other operation knob at the opposite portions of the first and second operation knobs.
When a washer is arranged between the opposite portions of the first and second operation knobs, the washer prevents the convex portion from entering the concave portion.
When the washer is not arranged between the opposite parts of the first and second operation knobs, the convex portion enters the concave portion when the first and second operation knobs are relatively pressed and rotated. It is preferable to do so.

軸方向に並べて配置される第1,第2の各操作つまみは、一方の操作つまみに他方の操作つまみを押し当てることで、容易に相互間の位置決めをすることができ、組み立て作業性が向上する。ここで、各操作つまみを円滑に回転動作させるために、各操作つまみの間には座金を配置することが好ましい。しかし、組み立て作業において、この座金を配置し忘れることもある。そこで、上述のように構成することで、第1,第2の各操作つまみを相対的に押圧回転させるだけで、座金の有無を容易に検査することが可能となる。
すなわち、座金が配置されていないときには、第1,第2の各操作つまみを相対的に押圧回転させたとき、凹部へ凸部が入り込むので引っ掛かりが生じる。一方、座金が配置されているときは、凹部への凸部の入り込みが当該座金に阻まれるので、引っ掛かりが生じることなく、円滑に回転させることができる。この違いによって、座金の有無を容易に検査することができる。
The first and second operation knobs arranged side by side in the axial direction can be easily positioned between each other by pressing the other operation knob against one operation knob, improving assembly workability. To do. Here, in order to smoothly rotate each operation knob, it is preferable to arrange a washer between each operation knob. However, in the assembly work, it is possible to forget to place this washer. Therefore, with the above-described configuration, it is possible to easily inspect the presence or absence of a washer simply by relatively pressing and rotating the first and second operation knobs.
That is, when the washer is not arranged, when the first and second operation knobs are relatively pressed and rotated, the convex portion enters the concave portion, so that a catch occurs. On the other hand, when the washer is arranged, the convex portion is prevented from entering the concave portion by the washer, so that the washer can be smoothly rotated without being caught. Due to this difference, the presence or absence of washers can be easily inspected.

また、2軸2連型可変抵抗器には、一方の回転軸に第1の操作つまみを180゜異なる2つの角度位置で装着でき、そのうち一方の角度位置が第1の操作つまみの正規の装着位置となっている構成のものが多い。
かかる構成の2軸2連型可変抵抗器を用いるときは、第1の操作つまみに対するストッパを設けることが好ましい。
当該ストッパは、
一方の回転軸に第1の操作つまみが正規の装着位置で装着されているときは、当該第1の操作つまみの回転範囲を規制することなく、2軸2連型可変抵抗器の規定範囲を当該第1の操作つまみが回転し、
一方の回転軸に第1の操作つまみが正規の装着位置で装着されていないときは、当該第1の操作つまみの回転範囲を規制して、2軸2連型可変抵抗器の規定範囲を当該第1の操作つまみが回転できない構成とする。
In addition, the first operation knob can be mounted on one of the rotating shafts at two different angle positions by 180 ° on the two-axis dual variable resistor, and one of the angle positions is the regular mounting of the first operation knob. Many of them have a position.
When using a biaxial dual variable resistor having such a configuration, it is preferable to provide a stopper for the first operation knob.
The stopper is
When the first operation knob is mounted on one of the rotating shafts at the normal mounting position, the specified range of the 2-axis dual variable resistor can be set without restricting the rotation range of the first operating knob. The first operation knob rotates,
When the first operation knob is not mounted on one of the rotating shafts at the proper mounting position, the rotation range of the first operating knob is restricted and the specified range of the 2-axis dual variable resistor is set. The first operation knob is configured so that it cannot rotate.

このように構成することで、組み立て作業後に第1の操作つまみを回転させて、2軸2連型可変抵抗器の規定範囲を第1の操作つまみが回転できるか否かを確認するだけで、第1の操作つまみが正規の装着位置に装着されているか否かを容易に検査することができる。 With this configuration, it is only necessary to rotate the first operation knob after the assembly work and check whether the first operation knob can rotate within the specified range of the 2-axis dual variable resistor. It is possible to easily inspect whether or not the first operation knob is mounted in the proper mounting position.

また、ケース本体は、一端面が開口し内部に第1,第2の各調光制御回路及び電源回路の収納空間を有する筐体と、この筐体の開口面に装着される蓋体とを含む構成として、2軸2連型可変抵抗器は、蓋体に固定する構成とすることが好ましい。
2軸2連型可変抵抗器は、後述する可変抵抗器実装基板に固定することもできるが、その場合は組み立て誤差に伴い、回転軸の蓋体からの突き出し量にばらつきを生じるおそれがあり、当該回転軸に装着される第1,第2の各操作つまみの位置も不安定となる。
そこで、上述した構成とすることで、蓋体を基準に2軸2連型可変抵抗器の回転軸を位置決めすることができ、さらに当該回転軸に装着される第1,第2の各操作つまみも蓋体を基準に安定して位置決めすることができる。
Further, the case body has a housing having one end open and having storage spaces for the first and second dimming control circuits and the power supply circuit inside, and a lid body attached to the opening surface of the housing. As a configuration including the biaxial dual variable resistor, it is preferable that the biaxial dual variable resistor is fixed to the lid.
The 2-axis dual variable resistor can be fixed to the variable resistor mounting board described later, but in that case, the amount of protrusion of the rotating shaft from the lid may vary due to an assembly error. The positions of the first and second operation knobs mounted on the rotating shaft also become unstable.
Therefore, with the above-described configuration, the rotation axis of the 2-axis dual variable resistor can be positioned with reference to the lid, and the first and second operation knobs mounted on the rotation axis can be positioned. Can be stably positioned with reference to the lid.

また、本発明の調光器は、
第1,第2の各調光制御回路の中心となるマイコンを搭載してケース本体の筐体内に収納される制御基板と、
電源回路を搭載してケース本体の筐体内に収納される電源基板と、
2軸2連型可変抵抗器に実装され当該2軸2連型可変抵抗器のインタフェースを構成する可変抵抗器実装基板と、を備えた構成とし、
可変抵抗器実装基板は、2軸2連型可変抵抗器の回転軸と平行な抵抗器本体側面に配置ることが好ましい。
Further, the dimmer of the present invention is
A control board on which a microcomputer, which is the core of each of the first and second dimming control circuits, is mounted and housed in the housing of the case body, and
A power supply board equipped with a power supply circuit and stored inside the case body,
It is configured to include a variable resistor mounting board that is mounted on a 2-axis dual variable resistor and constitutes an interface of the dual-axis dual variable resistor.
The variable resistor mounting board is preferably arranged on the side surface of the resistor body parallel to the rotation axis of the dual-axis dual variable resistor.

2軸2連型可変抵抗器は、一般に2個の可変抵抗を軸方向に連設した構成となっているものが多い。かかる構成の場合、回転軸と平行な抵抗器本体側面の寸法が軸方向に延びて大きくなる。そこで、軸方向に大きくなった抵抗器本体の側面に可変抵抗器実装基板を配置することで、可変抵抗器実装基板の抵抗器本体からの突き出し量を抑制できるので、ケース本体内のスペースへ無駄なく効率的に可変抵抗器実装基板を配置することが可能となる。 In general, many 2-axis dual-type variable resistors have a configuration in which two variable resistors are connected in the axial direction. In the case of such a configuration, the dimension of the side surface of the resistor body parallel to the rotation axis extends in the axial direction and becomes large. Therefore, by arranging the variable resistor mounting board on the side surface of the resistor body that has become larger in the axial direction, the amount of protrusion of the variable resistor mounting board from the resistor body can be suppressed, which wastes space in the case body. It is possible to efficiently arrange the variable resistor mounting board without any problem.

さらに、制御基板と可変抵抗器実装基板を、可撓性を有する接続ケーブルによって電気的に接続する構成とした場合は、
可変抵抗器実装基板には、接続ケーブルの一端側が抵抗器本体の側面近傍でかつ当該側面と平行な方向から差し込み接続されるケーブル接続部を設けてある。また、制御基板には、接続ケーブルの他端側が当該制御基板の表面近傍でかつ当該表面と平行な方向から差し込み接続されるケーブル接続部を設けた構成とすることが好ましい。
Further, when the control board and the variable resistor mounting board are electrically connected by a flexible connection cable, the configuration is such that the control board and the variable resistor mounting board are electrically connected.
The variable resistor mounting board is provided with a cable connection portion in which one end side of the connection cable is inserted and connected near the side surface of the resistor body and from a direction parallel to the side surface. Further, it is preferable that the control board is provided with a cable connection portion in which the other end side of the connection cable is inserted and connected near the surface of the control board and from a direction parallel to the surface.

可変抵抗器実装基板のケーブル接続部を上述した構成とすることで、2軸2連型可変抵抗器の側面近傍に沿って、ケース本体内のスペースへ無駄なく効率的に当該ケーブル接続部を配置することが可能となる。さらに、制御基板のケーブル接続部を上述した構成とすることで、制御基板の表面に沿って、ケース本体内のスペースへ無駄なく効率的に当該ケーブル接続部を配置することが可能となる。 By configuring the cable connection part of the variable resistor mounting board as described above, the cable connection part is efficiently arranged in the space inside the case body along the vicinity of the side surface of the 2-axis dual variable resistor. It becomes possible to do. Further, by configuring the cable connection portion of the control board as described above, it is possible to efficiently arrange the cable connection portion in the space inside the case body along the surface of the control board without waste.

また、本発明の照明システムは、調光制御信号に応じて光源を調光制御する照明器具と、上述した構成の調光器と、を含むことを特徴とする。かかる照明システムは、調光器が小形であり、家庭用の照明器具を調光する用途にも好適である。 Further, the lighting system of the present invention is characterized by including a luminaire for dimming and controlling a light source in response to a dimming control signal, and a dimmer having the above-described configuration. Such a lighting system has a small dimmer and is also suitable for dimming household lighting fixtures.

以上説明したように、本発明の調光器によれば、家庭用の照明器具を調光する用途にも好適な大きさであって、2系統の照明器具に対して調光レベルを別々に制御することができるので、複数系統の照明器具の調光レベルを制御する調光システムを構築するにあたり、必要となる調光器の個数を減らして設置スペースの狭小化が実現可能となる。
しかも、第1,第2の各操作つまみを軸方向に並べて配置することで、各操作つまみを一緒に回転操作するだけの極めて容易な操作をもって、第1,第2の各調光制御回路から同じ調光制御信号が出力され、各系統の照明器具を同じ調光レベルに制御することが可能となる。
As described above, according to the dimmer of the present invention, the size is suitable for dimming household lighting fixtures, and the dimming levels are set separately for two systems of lighting fixtures. Since it can be controlled, it is possible to reduce the number of dimmers required for constructing a dimming system that controls the dimming level of a plurality of lighting fixtures, and to reduce the installation space.
Moreover, by arranging the first and second operation knobs side by side in the axial direction, it is possible to perform an extremely easy operation of rotating each operation knob together from the first and second dimming control circuits. The same dimming control signal is output, and it becomes possible to control the lighting fixtures of each system to the same dimming level.

以下、この発明の実施の形態について図面を参照して詳細に説明する。
本実施形態に係る照明システムは、図1に示すように、商用電源100と、複数の照明器具200と、各照明器具200を調光する調光器1とを含んでいる。複数の照明器具200は、電源線300を介して商用電源100に並列に接続され、当該商用電源100から交流100Vの電力を供給されて点灯する。なお、電源線300には、照明器具200及び調光器1への電源供給をオン・オフするための切替スイッチ500が直列に接続してある。
複数の照明器具200は、共通に調光レベルが制御される照明器具200が同じ系統にまとめて管理される。例えば、図1では、照明器具200a,200bを同じ系統(第1の系統200A)として一括して制御するようにしてある。同様に、照明器具200c,200dを同じ系統(第2の系統200B)として一括して制御するようにしている。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the lighting system according to the present embodiment includes a commercial power source 100, a plurality of lighting fixtures 200, and a dimmer 1 for dimming each lighting fixture 200. The plurality of lighting fixtures 200 are connected in parallel to the commercial power source 100 via the power supply line 300, and are lit by being supplied with AC 100V power from the commercial power source 100. A changeover switch 500 for turning on / off the power supply to the lighting fixture 200 and the dimmer 1 is connected in series to the power supply line 300.
In the plurality of lighting fixtures 200, the lighting fixtures 200 whose dimming level is controlled in common are collectively managed in the same system. For example, in FIG. 1, the lighting fixtures 200a and 200b are collectively controlled as the same system (first system 200A). Similarly, the lighting fixtures 200c and 200d are collectively controlled as the same system (second system 200B).

調光器1は、電源線300を介して商用電源100に接続され、当該商用電源100から交流100Vの電力を供給されて動作する。そして、照明器具200の調光レベルを制御する調光制御信号を、電源線300とは別に配線した信号線400を介して照明器具200へ出力する。
照明器具200には、LED(発光ダイオード)等の光源と、この光源の調光レベルを調光制御信号に応じて変化させる制御回路とが組み込まれている。制御回路は、調光器1から調光制御信号を入力し、当該調光制御信号に応じて、光源の明るさや色合い等の調光レベルを変更する。
The dimmer 1 is connected to a commercial power source 100 via a power supply line 300, and operates by being supplied with AC 100V power from the commercial power source 100. Then, the dimming control signal for controlling the dimming level of the luminaire 200 is output to the luminaire 200 via the signal line 400 wired separately from the power supply line 300.
The luminaire 200 incorporates a light source such as an LED (light emitting diode) and a control circuit that changes the dimming level of the light source according to a dimming control signal. The control circuit inputs a dimming control signal from the dimmer 1 and changes the dimming level such as the brightness and hue of the light source according to the dimming control signal.

調光制御信号を用いた調光方式の代表例としては、PWM信号(パルス幅変調信号)を調光制御信号とするPWM信号制御方式がある。同方式を採用した場合は、調光器1から出力されたPWM信号のデューティ比に応じて、照明器具200に組み込まれた制御回路が、光源の調光レベルを変化させる。
なお、本実施形態の照明システムと調光器1が採用可能な調光方式としては、PWM信号制御方式に限定されるものではない。
A typical example of a dimming method using a dimming control signal is a PWM signal control method in which a PWM signal (pulse width modulation signal) is used as a dimming control signal. When this method is adopted, the control circuit incorporated in the luminaire 200 changes the dimming level of the light source according to the duty ratio of the PWM signal output from the dimmer 1.
The dimming method that can be adopted by the lighting system and the dimmer 1 of the present embodiment is not limited to the PWM signal control method.

本実施形態の調光器1は、2つの調光制御信号を出力する機能を備えており、一方の調光制御信号により第1の系統200Aに含まれる照明器具200a,200bの調光レベルを制御するとともに、他方の調光制御信号により第2の系統200Bに含まれる照明器具200c,200dの調光レベルを制御する。このように、1個の調光器1で2つの系統に含まれる照明器具200の調光レベルを制御することができるので、省スペース化を図ることができる。なお、制御対象となる照明器具200を3つ以上の系統に区分けするときは、さらに調光器1を増設する必要があるものの、必要個数は従来の半分で済む。 The dimmer 1 of the present embodiment has a function of outputting two dimming control signals, and the dimming level of the lighting fixtures 200a and 200b included in the first system 200A is determined by one of the dimming control signals. In addition to controlling, the dimming level of the lighting fixtures 200c and 200d included in the second system 200B is controlled by the other dimming control signal. In this way, one dimmer 1 can control the dimming level of the lighting fixture 200 included in the two systems, so that space can be saved. When the lighting fixture 200 to be controlled is divided into three or more systems, it is necessary to add a dimmer 1 further, but the required number is only half of the conventional one.

次に、本実施形態に係る調光器1について詳細に説明する。

ケース本体10の蓋体12には、図2及び図4に示すように、2軸2連型可変抵抗器50が組み込まれている。2軸2連型可変抵抗器50は、内蔵する2個の可変抵抗を、同軸状に設けた2本の回転軸をもって各々操作する構成のボリュームである。
本実施形態で用いる2軸2連型可変抵抗器50は、図7に示すような外観構成をしており、立方体形状の抵抗器本体51のボス面から第1の回転軸52と第2の回転軸53が同軸状に突き出している。抵抗器本体51の側面51aは、これら各回転軸52,53と平行に配置されている。
As shown in FIGS. 2 and 4, a biaxial dual variable resistor 50 is incorporated in the lid 12 of the case body 10. The 2-axis dual variable resistor 50 is a volume having a configuration in which two built-in variable resistors are operated by two coaxially provided rotating shafts.
The 2-axis dual variable resistor 50 used in the present embodiment has an external configuration as shown in FIG. 7, and has a cubic-shaped resistor body 51 from the boss surface to the first rotating shaft 52 and the second rotating shaft 52. The rotating shaft 53 protrudes coaxially. The side surface 51a of the resistor main body 51 is arranged in parallel with the respective rotating shafts 52 and 53.

抵抗器本体51には、2個の可変抵抗が軸方向に並べて内蔵してある。したがって、2軸2連型可変抵抗器50は、同じタイプで1個の可変抵抗を内蔵する1軸単連型可変抵抗器よりも、抵抗器本体51の側面51aが軸方向に延びて大きくなる。
この抵抗器本体51の側面51aには、2軸2連型可変抵抗器50のインタフェースを構成する可変抵抗器実装基板60が配設してある。
このように、軸方向に大きくなった抵抗器本体51の側面51aに可変抵抗器実装基板60を配置することで、可変抵抗器実装基板60の抵抗器本体51からの突き出し量を抑制できるので、ケース本体10内のスペースへ無駄なく効率的に可変抵抗器実装基板60を配置することが可能となる。
Two variable resistors are built in the resistor main body 51 side by side in the axial direction. Therefore, in the biaxial dual variable resistor 50, the side surface 51a of the resistor main body 51 extends in the axial direction and becomes larger than that of the single axis single variable resistor 50 having one variable resistor of the same type. ..
On the side surface 51a of the resistor main body 51, a variable resistor mounting board 60 that constitutes an interface of the dual-axis dual variable resistor 50 is arranged.
By arranging the variable resistor mounting board 60 on the side surface 51a of the resistor main body 51 which is enlarged in the axial direction in this way, the amount of protrusion of the variable resistor mounting board 60 from the resistor main body 51 can be suppressed. The variable resistor mounting board 60 can be efficiently arranged in the space inside the case body 10 without waste.

2軸2連型可変抵抗器50とともに可変抵抗器実装基板60もケース本体10の蓋体12に固定されるので、ケース本体10の筐体11内へ収納される制御基板20とは物理的に離れている。そこで、図2(b)に拡大して示すように、可変抵抗器実装基板60と制御基板20は、可撓性を有する接続ケーブル61を介して電気的に接続する構成としてある。 Since the variable resistor mounting board 60 is also fixed to the lid 12 of the case body 10 together with the 2-axis dual variable resistor 50, it is physically different from the control board 20 housed in the housing 11 of the case body 10. is seperated. Therefore, as shown in an enlarged manner in FIG. 2B, the variable resistor mounting substrate 60 and the control substrate 20 are configured to be electrically connected via a flexible connection cable 61.

ここで、可変抵抗器実装基板60には、接続ケーブル61の一端側が抵抗器本体51の側面51a近傍でかつ当該側面51aと平行な方向から差し込み接続されるケーブル接続部62を設けてある。このように構成することで、2軸2連型可変抵抗器50の側面51aに沿って、ケース本体10内のスペースへ無駄なく効率的に当該ケーブル接続部62を配置することが可能となる。 Here, the variable resistor mounting board 60 is provided with a cable connecting portion 62 in which one end side of the connecting cable 61 is inserted and connected in the vicinity of the side surface 51a of the resistor main body 51 and from a direction parallel to the side surface 51a. With this configuration, the cable connection portion 62 can be efficiently and efficiently arranged in the space inside the case body 10 along the side surface 51a of the dual-axis dual variable resistor 50.

また、制御基板20には、接続ケーブル61の他端側が当該制御基板20の表面近傍でかつ当該表面と平行な方向から差し込み接続されるケーブル接続部27を設けてある。このように構成することで、制御基板20の表面に沿って、ケース本体10内のスペースへ無駄なく効率的に当該ケーブル接続部27を配置することが可能となる。 Further, the control board 20 is provided with a cable connection portion 27 in which the other end side of the connection cable 61 is inserted and connected in the vicinity of the surface of the control board 20 and from a direction parallel to the surface. With this configuration, the cable connection portion 27 can be efficiently and efficiently arranged in the space inside the case body 10 along the surface of the control board 20.

図8及び図9に示すように、2軸2連型可変抵抗器50の第1の回転軸52には第1の操作つまみ70が装着され、第2の回転軸53には第2の操作つまみ80が装着される。
すなわち、2軸2連型可変抵抗器50の第1の回転軸52には、先端部で周方向に180゜離れた2箇所(すなわち、中心軸を挟む対向位置)に位置決め用の縦溝52aが形成してある。第1の操作つまみ70には、内部壁71の下面から円筒状の嵌合部72が軸方向に突出して形成してあり、さらにこの嵌合部72における内周面の2箇所(周方向に180゜離れた2箇所)に、縦溝52aへ係合する突条72aが形成してある。第1の操作つまみ70は、突条72aを縦溝52aに係合させながら、円筒状の嵌合部72に第1の回転軸52に外周面を嵌め込むことで、第1の回転軸52に装着される。
このとき、縦溝52aへ突条72aを係合させることで、2軸2連型可変抵抗器50にあらかじめ設定された第1の回転軸52に対する回転動作の原点と、第1の操作つまみ70にあらかじめ設定された回転操作の原点とを、自動的に合致させることができるように構成されている。
As shown in FIGS. 8 and 9, a first operation knob 70 is attached to the first rotating shaft 52 of the dual-axis dual variable resistor 50, and a second operation is applied to the second rotating shaft 53. The knob 80 is attached.
That is, the first rotating shaft 52 of the two-axis dual variable resistor 50 has a vertical groove 52a for positioning at two locations (that is, opposite positions sandwiching the central axis) at the tip portion 180 ° apart in the circumferential direction. Is formed. In the first operation knob 70, a cylindrical fitting portion 72 is formed so as to project in the axial direction from the lower surface of the inner wall 71, and further, two positions (in the circumferential direction) of the inner peripheral surface of the fitting portion 72 are formed. At two locations 180 ° apart), ridges 72a that engage with the flutes 52a are formed. The first operation knob 70 fits the outer peripheral surface of the first rotating shaft 52 into the cylindrical fitting portion 72 while engaging the ridge 72a with the vertical groove 52a, whereby the first rotating shaft 52 It is attached to.
At this time, by engaging the ridge 72a with the vertical groove 52a, the origin of the rotational operation with respect to the first rotary shaft 52 preset in the dual-axis dual variable resistor 50 and the first operation knob 70 It is configured so that it can be automatically matched with the origin of the rotation operation set in advance.

一方、2軸2連型可変抵抗器50の第2の回転軸53には、先端部の一部に位置決め用の切欠き53aが形成してあり、これにより同回転軸の先端部は横断面がD字形状に形成されている。第2の操作つまみ80には、内底部から装着部81が軸方向に突出しており、この装着部81に横断面がD字形状をした嵌合中空部82が軸方向に延びるように形成されている。この嵌合中空部82には、内壁に沿ってばね部材83が圧入される。そして、第2の操作つまみ80は、嵌合中空部82に第2の回転軸53の先端部を嵌め込むことで、第2の回転軸53に装着される。このとき、ばね部材83のばね力によって、第2の回転軸53の先端部は嵌合中空部82でがたつき無く固定される。
2軸2連型可変抵抗器50にあらかじめ設定された第2の回転軸53に対する回転動作の原点と、第2の操作つまみ80にあらかじめ設定された回転操作の原点とは、横断面がD字形状に形成された第2の回転軸53の先端部を、同じく横断面がD字形状に形成された第2の操作つまみ80の嵌合中空部82に合わせることで、自動的に合致させることができる。
On the other hand, the second rotating shaft 53 of the two-axis dual variable resistor 50 is formed with a notch 53a for positioning in a part of the tip portion thereof, whereby the tip portion of the rotating shaft has a cross section. Is formed in a D shape. In the second operation knob 80, a mounting portion 81 protrudes in the axial direction from the inner bottom portion, and a fitting hollow portion 82 having a D-shaped cross section is formed in the mounting portion 81 so as to extend in the axial direction. ing. A spring member 83 is press-fitted into the fitting hollow portion 82 along the inner wall. Then, the second operation knob 80 is attached to the second rotating shaft 53 by fitting the tip end portion of the second rotating shaft 53 into the fitting hollow portion 82. At this time, due to the spring force of the spring member 83, the tip end portion of the second rotating shaft 53 is fixed by the fitting hollow portion 82 without rattling.
The cross section of the origin of the rotational operation with respect to the second rotary shaft 53 preset in the dual-axis dual variable resistor 50 and the origin of the rotary operation preset in the second operation knob 80 are D-shaped. The tip of the second rotating shaft 53 formed in a shape is automatically matched by aligning with the fitting hollow portion 82 of the second operation knob 80 whose cross section is also formed in a D shape. Can be done.

また、第1の操作つまみ70は、上面から軸方向に窪み空間73が形成してあり、この窪み空間73内に第2の操作つまみ80の装着部81が挿入配置される。このとき、第2の操作つまみ80における装着部81の先端面と、第1の操作つまみ70における窪み空間73内にある内部壁71の上面とが対向し、それら対向部位の間に円盤状の座金90が配置される。 Further, the first operation knob 70 has a recessed space 73 formed in the axial direction from the upper surface, and the mounting portion 81 of the second operation knob 80 is inserted and arranged in the recessed space 73. At this time, the tip surface of the mounting portion 81 of the second operation knob 80 and the upper surface of the inner wall 71 in the recessed space 73 of the first operation knob 70 face each other, and a disk shape is formed between the facing portions. The washer 90 is arranged.

第1の操作つまみ70は、2軸2連型可変抵抗器50とともに、照明器具200の調光レベルを調節するための第1の調光操作手段を構成する。既述した第1の調光制御回路は、この第1の調光操作手段の操作(具体的には、第1の操作つまみ70の操作)に応じた調光制御信号を発生させる。例えば、第1の調光制御回路が調光制御信号としてPWM信号を発生させる構成のときは、第1の調光操作手段の操作に応じて、PWM信号のデューティー比を変化させる。 The first operation knob 70, together with the two-axis dual variable resistor 50, constitutes a first dimming operation means for adjusting the dimming level of the luminaire 200. The first dimming control circuit described above generates a dimming control signal according to the operation of the first dimming operation means (specifically, the operation of the first operation knob 70). For example, when the first dimming control circuit is configured to generate a PWM signal as a dimming control signal, the duty ratio of the PWM signal is changed according to the operation of the first dimming operation means.

同様に、第2の操作つまみ80は、2軸2連型可変抵抗器50とともに、照明器具200の調光レベルを調節するための第2の調光操作手段を構成する。既述した第2の調光制御回路は、この第2の調光操作手段の操作(具体的には、第2の操作つまみ80の操作)に応じた調光制御信号を発生させる。例えば、第2の調光制御回路が調光制御信号としてPWM信号を発生させる構成のときは、第2の調光操作手段の操作に応じて、PWM信号のデューティー比を変化させる。 Similarly, the second operation knob 80, together with the two-axis dual variable resistor 50, constitutes a second dimming operation means for adjusting the dimming level of the luminaire 200. The second dimming control circuit described above generates a dimming control signal according to the operation of the second dimming operation means (specifically, the operation of the second operation knob 80). For example, when the second dimming control circuit is configured to generate a PWM signal as a dimming control signal, the duty ratio of the PWM signal is changed according to the operation of the second dimming operation means.

図9及び図3に示すように、第1,第2の各操作つまみ70,80を軸方向に並べて配置することで、各操作つまみ70,80を一緒に回転操作することができる。この回転操作により、第1,第2の各調光制御回路は同じ調光制御信号を発生するので、図1に示した各系統200A,200Bの照明器具200を、同じ調光制御信号によって同じ調光レベルに制御することが可能となる。
もちろん、各操作つまみ70,80を別々に回転操作して、各系統200A,200Bの照明器具200をそれぞれ異なった調光レベルに制御することもできる。
As shown in FIGS. 9 and 3, by arranging the first and second operation knobs 70 and 80 side by side in the axial direction, the operation knobs 70 and 80 can be rotated together. By this rotation operation, the first and second dimming control circuits generate the same dimming control signal. Therefore, the lighting fixtures 200 of the systems 200A and 200B shown in FIG. 1 are the same by the same dimming control signal. It is possible to control the dimming level.
Of course, it is also possible to rotate the operation knobs 70 and 80 separately to control the lighting fixtures 200 of the systems 200A and 200B to different dimming levels.

図8及び図9に示すように、第1,第2の各操作つまみ70,80は、一方の操作つまみに対し座金90を介して他方の操作つまみを押し当てることで相互間の位置決めがされる構成としてある。このように、一方の操作つまみに他方の操作つまみを押し当てることで、容易に相互間の位置決めをすることができ、組み立て作業性が向上する。しかも、このように位置決めすることで、第1,第2の各操作つまみ70,80の相互間に大きな隙間が生じて操作性を低下させるおそれがなくなる。 As shown in FIGS. 8 and 9, the first and second operation knobs 70 and 80 are positioned between each other by pressing the other operation knob against one operation knob via the washer 90. It is a configuration. In this way, by pressing the other operation knob against one operation knob, positioning between the two can be easily performed, and the assembly workability is improved. Moreover, by positioning in this way, there is no possibility that a large gap is generated between the first and second operation knobs 70 and 80 and the operability is deteriorated.

座金90は、第1,第2の各操作つまみ70,80を個々に回転操作する際の摩擦抵抗を低減し、円滑な操作性を確保するために必要な部品である。しかし、この座金90は小さく、調光器1の組立作業において、取付けを忘れてしまう可能性がある。かかる作業ミスが生じても、2軸2連型可変抵抗器50の各回転軸52,53に各操作つまみ70,80を装着した後は、各操作つまみ70,80の間に座金90が無いことを外部から視覚的に確認することができない。 The washer 90 is a component necessary for reducing frictional resistance when the first and second operation knobs 70 and 80 are individually rotated to ensure smooth operability. However, the washer 90 is small, and there is a possibility that the washer 1 may be forgotten to be attached in the assembling work. Even if such a work error occurs, there is no washer 90 between the operation knobs 70 and 80 after the operation knobs 70 and 80 are attached to the rotation shafts 52 and 53 of the dual-axis dual variable resistor 50. It cannot be visually confirmed from the outside.

そこで、図10に示すように、第1,第2の各操作つまみ70,80の対向部位に、それぞれ凹部74と凸部84が形成してある。具体的には、第2の操作つまみ80における装着部81の先端面に、3個の凸部84を周方向にほぼ120゜の間隔をおいて形成してあり、一方、第1の操作つまみ70における窪み空間73内にある内部壁71の上面であって、第2の操作つまみ80における装着部81の先端面と対向する部位に、凹部74を周方向に3分割して形成してある。
これら凹部74と凸部84が形成された対向部位(すなわち、第1,第2の各操作つまみ70,80の対向部位)の間には、上述したとおり座金90が配置される。
Therefore, as shown in FIG. 10, a concave portion 74 and a convex portion 84 are formed at the opposite portions of the first and second operation knobs 70 and 80, respectively. Specifically, three convex portions 84 are formed on the tip surface of the mounting portion 81 of the second operation knob 80 at intervals of approximately 120 ° in the circumferential direction, while the first operation knob is formed. The recess 74 is formed by dividing the recess 74 into three parts in the circumferential direction on the upper surface of the inner wall 71 in the recess space 73 in the 70 and facing the tip surface of the mounting portion 81 of the second operation knob 80. ..
As described above, the washer 90 is arranged between the concave portion 74 and the opposite portion where the convex portion 84 is formed (that is, the opposite portions of the first and second operation knobs 70 and 80).

凹部74と凸部84は、第1,第2の各操作つまみ70,80の対向部位の間に座金90が配置されているときは、凹部74への凸部84の入り込みが座金90によって阻まれる(図11(a)参照)。一方、第1,第2の各操作つまみ70,80の対向部位の間に座金90が配置されていないときには、第1,第2の各操作つまみ70,80を相対的に押圧回転させたとき、凹部74へ凸部84が入り込む(図11(b)参照)。 When the washer 90 is arranged between the opposite portions of the first and second operation knobs 70 and 80, the concave portion 74 and the convex portion 84 are prevented from entering the concave portion 74 by the washer 90. (See FIG. 11 (a)). On the other hand, when the washer 90 is not arranged between the opposite portions of the first and second operation knobs 70 and 80, when the first and second operation knobs 70 and 80 are relatively pressed and rotated. , The convex portion 84 enters the concave portion 74 (see FIG. 11B).

上述のように構成することで、第1,第2の各操作つまみ70,80を相対的に押圧回転させるだけで、座金90の有無を容易に検査することが可能となる。
すなわち、座金90が配置されていないときには、第1,第2の各操作つまみ70,80を相対的に押圧回転させたとき、凹部74へ凸部84が入り込むので引っ掛かりが生じる(図11(b)参照)。一方、座金90が配置されているときは、凹部74への凸部84の入り込みが当該座金90に阻まれるので、引っ掛かりが生じることなく、円滑に回転させることができる(図11(a)参照)。この違いによって、座金90の有無を容易に検査することができる。
With the above configuration, the presence or absence of the washer 90 can be easily inspected only by relatively pressing and rotating the first and second operation knobs 70 and 80.
That is, when the washer 90 is not arranged, when the first and second operation knobs 70 and 80 are relatively pressed and rotated, the convex portion 84 enters the concave portion 74, so that a catch occurs (FIG. 11 (b). )reference). On the other hand, when the washer 90 is arranged, the convex portion 84 is blocked from entering the concave portion 74 by the washer 90, so that the washer 90 can be smoothly rotated without being caught (see FIG. 11A). ). Due to this difference, the presence or absence of the washer 90 can be easily inspected.

なお、凸部84は周方向にほぼ120゜の間隔をおいて3個形成する構成に限定されず、凹部74は周方向に3分割して形成する構成に限定されるものではない。また、第1の操作つまみ70に凸部84を形成し、第2の操作つまみ80に凹部74を形成することもできる。 The convex portion 84 is not limited to the configuration in which three convex portions 84 are formed at intervals of approximately 120 ° in the circumferential direction, and the concave portion 74 is not limited to the configuration in which the concave portion 74 is formed by dividing into three in the circumferential direction. Further, the convex portion 84 can be formed on the first operation knob 70, and the concave portion 74 can be formed on the second operation knob 80.

上述したように、第1の操作つまみ70は、周方向に180゜離れた2箇所に形成した突条72aを、第1の回転軸52における先端部で周方向に180゜離れた2箇所(すなわち、中心軸を挟む対向位置)に形成した位置決め用の縦溝52aに係合させることで、2軸2連型可変抵抗器50にあらかじめ設定された第1の回転軸52に対する回転動作の原点と、第1の操作つまみ70にあらかじめ設定された回転操作の原点とを、自動的に合致させることができるように構成されている。 As described above, in the first operation knob 70, the ridges 72a formed at two locations 180 ° apart in the circumferential direction are separated from each other by 180 ° in the circumferential direction at the tip of the first rotation shaft 52 ( That is, by engaging with the vertical groove 52a for positioning formed at the opposite positions sandwiching the central axis), the origin of the rotational operation with respect to the first rotating shaft 52 preset in the dual-axis dual variable resistor 50. And the origin of the rotation operation set in advance on the first operation knob 70 are configured to be automatically matched.

ところが、縦溝52aと突条72aとは、第1の回転軸52に対して第1の操作つまみ70を180゜異なる2つの角度位置で係合させることができてしまう。
第1の回転軸52に対して第1の操作つまみ70を正規の角度位置で装着した場合は、第1の操作つまみ70に設けられた目盛り75の位置が、第1の回転軸52の回転に伴い変化する可変抵抗の抵抗値の大きさに対応して移動する。一方、第1の回転軸52に対して第1の操作つまみ70を正規の角度位置から180゜ずれた状態で装着した場合は、第1の操作つまみ70に設けられた目盛り75が、第1の回転軸52の回転に伴い変化する可変抵抗の抵抗値の大きさ示す位置からずれた状態で移動することになる。
However, the flutes 52a and the ridges 72a can engage the first operation knob 70 with the first rotation shaft 52 at two different angle positions by 180 °.
When the first operation knob 70 is attached to the first rotation shaft 52 at a regular angle position, the position of the scale 75 provided on the first operation knob 70 is the rotation of the first rotation shaft 52. It moves according to the magnitude of the resistance value of the variable resistor that changes with it. On the other hand, when the first operation knob 70 is attached to the first rotation shaft 52 in a state of being deviated by 180 ° from the regular angle position, the scale 75 provided on the first operation knob 70 is the first. The variable resistance that changes with the rotation of the rotation shaft 52 of the above moves in a state deviated from the position indicated by the magnitude of the resistance value.

そこで、第1の操作つまみ70に対するストッパを設けることで、第1の操作つまみ70が正規の装着位置に装着されているか否かを容易に検査できるようにしている。
図8及び図2に示すように、本実施形態では調光器1を装着する取付枠42の表面側に化粧カバー44が装着される。そこで、本実施形態ではこの化粧カバー44に係止部44aを形成するとともに、第1の操作つまみ70から被係止部76を径方向に突き出して形成し、これら係止部44aと被係止部76とでストッパを構成してある。
なお、係止部44aの形成箇所は化粧カバー44に限定されず、例えば、取付枠42や調光器1のケース本体10であってもよい。
Therefore, by providing a stopper for the first operation knob 70, it is possible to easily inspect whether or not the first operation knob 70 is mounted at the proper mounting position.
As shown in FIGS. 8 and 2, in the present embodiment, the decorative cover 44 is mounted on the surface side of the mounting frame 42 on which the dimmer 1 is mounted. Therefore, in the present embodiment, the locking portion 44a is formed on the decorative cover 44, and the locked portion 76 is formed so as to protrude in the radial direction from the first operation knob 70, and is locked with the locking portion 44a. A stopper is formed by the portion 76.
The location where the locking portion 44a is formed is not limited to the decorative cover 44, and may be, for example, the mounting frame 42 or the case body 10 of the dimmer 1.

ストッパは、第1の回転軸52に第1の操作つまみ70が正規の装着位置で装着されているときは、第1の操作つまみ70の回転範囲を規制することなく、2軸2連型可変抵抗器50の規定範囲(角度αの範囲)を第1の操作つまみ70が回転するように、係止部44aと被係止部76の形成位置を調整してある(図12(a)参照)。一方、第1の回転軸52に第1の操作つまみ70が正規の装着位置で装着されていないときは、係止部44aに被係止部76が当接して、第1の操作つまみ70の回転範囲が規制され、2軸2連型可変抵抗器50の規定範囲(角度αの範囲)よりも小さい回転角度範囲βとなるように、係止部44aと被係止部76の形成位置を調整してある(図12(b)参照)。 When the first operation knob 70 is mounted on the first rotation shaft 52 at the normal mounting position, the stopper is a two-axis dual type variable without restricting the rotation range of the first operation knob 70. The forming positions of the locking portion 44a and the locked portion 76 are adjusted so that the first operation knob 70 rotates within the specified range (range of the angle α) of the resistor 50 (see FIG. 12A). ). On the other hand, when the first operating knob 70 is not mounted on the first rotating shaft 52 at the proper mounting position, the locked portion 76 comes into contact with the locking portion 44a, and the first operating knob 70 The formation positions of the locking portion 44a and the locked portion 76 are set so that the rotation range is restricted and the rotation angle range β is smaller than the specified range (range of the angle α) of the 2-axis dual variable resistor 50. It has been adjusted (see FIG. 12B).

このように構成することで、組み立て作業後に第1の操作つまみ70を回転させて、2軸2連型可変抵抗器50の規定範囲を第1の操作つまみ70が回転できるか否かを確認するだけで、第1の操作つまみ70が正規の装着位置に装着されているか否かを容易に検査することができる。 With this configuration, the first operation knob 70 is rotated after the assembly work, and it is confirmed whether or not the first operation knob 70 can rotate within the specified range of the 2-axis dual variable resistor 50. Only by itself, it is possible to easily inspect whether or not the first operation knob 70 is mounted in the proper mounting position.

なお、本発明は上述した実施形態に限定されるものではなく、必要に応じて種々の変形実施や応用実施が可能であることは勿論である。 It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications and applications can be implemented as needed.
