Description

本発明は測色計に関し、詳しくは簡易な構成の携帯型の測色計に関する。   The present invention relates to a colorimeter, and more particularly to a portable colorimeter having a simple configuration.

測色計、色差計、光沢計等の光学測定機器は、主として携帯型と卓上に置いて使用する定置型との二タイプがある。   There are two types of optical measuring instruments such as a colorimeter, a color difference meter, and a gloss meter, mainly a portable type and a stationary type used on a table.

簡略な色測定を行う場合には、定置型は比較的大型であるため携帯型が主として使用されているが、携帯型であっても測定ヘッド部分のみが小型の携帯型であり、制御部及び表示部等を構成する測定器本体は定置型と変わらない大きさの別体構成のものが多かった（例えば、特許文献１及び２参照）。   When performing simple color measurement, since the stationary type is relatively large, the portable type is mainly used. However, even in the portable type, only the measurement head portion is a small portable type. In many cases, the main body of the measuring instrument constituting the display unit or the like has a separate structure that is the same size as the stationary type (see, for example, Patent Documents 1 and 2).

特に従来の光学測定機器は、種々の検査・試験・実験等に適用し得るような厳密且つ精緻な色測定に適したものであり、簡易的な色の違い程度を簡単に知りたい状況、例えば、調理や料理、壁紙や塗料、洋服生地や染色等のようにある程度の色差が正確に判別できればよいという状況に利用するには仕様・性能・価格等の点でオーバースペックであった。   In particular, conventional optical measuring instruments are suitable for rigorous and precise color measurement that can be applied to various inspections, tests, experiments, etc. It was over-spec in terms of specifications, performance, price, etc. to be used in situations where it is sufficient to be able to accurately distinguish a certain color difference, such as cooking, cooking, wallpaper, paint, clothes fabric and dyeing.

図１は本発明に係る測色計の一実施例を示す一部切欠正面図、図２は計測部の底面図、図３は表示部の平面図である。 The present invention will now be described in more detail with reference to the accompanying drawings.
FIG. 1 is a partially cutaway front view showing an embodiment of a colorimeter according to the present invention, FIG. 2 is a bottom view of a measurement unit, and FIG. 3 is a plan view of a display unit.

図１において、本発明に係る測色計は、片手で持てる大きさ及び形状のハンディタイプの本体１、光源２１と受光部２２とを有する計測部２、該計測部２を制御する制御部３、前記計測部２によって計測された結果を表示する表示部４と、測色操作を行う操作部５とから主として構成されている。   1, a colorimeter according to the present invention includes a handy-type main body 1 having a size and a shape that can be held with one hand, a measuring unit 2 having a light source 21 and a light receiving unit 22, and a control unit 3 for controlling the measuring unit 2. The display unit 4 displays a result measured by the measurement unit 2 and an operation unit 5 that performs a colorimetric operation.

計測部２は本体１の一部、具体的には先端部分下面側に設けられた窓部１１内に配設されており、制御部３は本体１内部に収納されており、表示部４は本体１の上面側、即ち、計測を行う際に計測者が見易い位置に配設されており、操作部５は本体１のグリップ部１２を持った際に操作し易い位置である該グリップ部１２の上面に配設されている。即ち、計測部分のみが携帯可能な小型ではあるが制御部等は別体の定置型である従来の携帯型のものとは異なり、各構成部材の全てが本体１内に組み込まれた構成を有している。   The measuring unit 2 is disposed in a part of the main body 1, specifically, a window portion 11 provided on the lower surface side of the tip portion, the control unit 3 is housed in the main body 1, and the display unit 4 is The grip portion 12 is disposed on the upper surface side of the main body 1, that is, at a position where the measurer can easily see when performing measurement, and the operation portion 5 is a position that is easy to operate when the grip portion 12 of the main body 1 is held. It is arrange | positioned at the upper surface. That is, unlike the conventional portable type in which only the measurement part is portable and the control unit is a separate stationary type, all the components are incorporated in the main body 1. doing.

前記計測部２の光源２１は白色ＬＥＤから成り、受光部２２の受光素子は三原色（Ｂ・Ｇ・Ｒ）の受光センサーから成る。白色ＬＥＤ、三原色受光センサーは公知のものを特別の制限なく利用でき、例えば、三原色受光センサーとしては、浜松ホトニクス社製ＲＧＢカラーセンサモジュール（チップ）、Ｓｉフォトダイオード等を利用できる。   The light source 21 of the measuring unit 2 is composed of a white LED, and the light receiving element of the light receiving unit 22 is composed of a light receiving sensor of three primary colors (B, G, R). As the white LED and the three primary color light receiving sensors, known ones can be used without any particular limitation. For example, as the three primary color light receiving sensors, RGB color sensor modules (chips) manufactured by Hamamatsu Photonics, Si photodiodes, or the like can be used.

制御部３としては、この種の光学測定機器に用いられる公知公用の半導体を挙げることができる。   Examples of the control unit 3 include publicly known semiconductors used in this type of optical measuring instrument.

表示部４は、計測部２によって計測された数値を表示可能であればよく、具体的には液晶画面や有機ＥＬ画面を採用することができる。表示される内容としては、Ｂ・Ｇ・Ｒ値の各平均や偏差等の数値や波形等が好ましい。例えば、浜松ホトニクス社製カラーセンサモジュールＣ９３０３やＣ９３１５を用いて、ＲＧＢ色情報を数値化し、バーグラフや百分率（図３参照）で表示することが好ましい。   The display part 4 should just be able to display the numerical value measured by the measurement part 2, and can employ | adopt a liquid crystal screen and an organic electroluminescent screen specifically ,. The displayed content is preferably a numerical value such as an average or deviation of B, G, and R values, a waveform, or the like. For example, it is preferable to digitize RGB color information using a color sensor module C9303 or C9315 manufactured by Hamamatsu Photonics and display it as a bar graph or percentage (see FIG. 3).

操作部５には、計測操作用のスイッチの他に、電源ＯＮ・ＯＦＦスイッチや、オートゲインコントロール（明るさ調整）やホワイトバランス調整機能の操作手段も用意されていることが好ましい。   In addition to the measurement operation switch, the operation unit 5 is preferably provided with operation means for a power ON / OFF switch, auto gain control (brightness adjustment), and white balance adjustment function.

計測に際しては、窓部１１を被計測物の計測対象面に近接ないしは当接させ、次に操作部５を操作（例えば、計測開始スイッチＯＮ操作）することにより、白色ＬＥＤ（一定の安定した照度のもの）から成る光源２１からの出力光束が被計測物表面に照射集光し、反射し、該出力光束の反射光を、Ｂ・Ｇ・Ｒ受光センサーから成る受光部２２が受光し、該受光部の出力信号に基づき制御部３が分光帯域に対応した波長範囲の反射率等を演算し、該演算値に基づいた結果を表示部４に表示する。   In the measurement, the window portion 11 is brought close to or in contact with the measurement target surface of the object to be measured, and then the operation portion 5 is operated (for example, the measurement start switch is turned on), whereby a white LED (a constant stable illuminance) is obtained. Output light beam from the light source 21 is irradiated and condensed on the surface of the object to be measured, reflected, and the reflected light of the output light beam is received by the light receiving unit 22 including a B, G, R light receiving sensor, Based on the output signal of the light receiving unit, the control unit 3 calculates the reflectance in the wavelength range corresponding to the spectral band, and displays the result based on the calculated value on the display unit 4.

計測時に被計測物と被計測物と計測部２との接触を防止するために、図２に示すように窓部１１に防護フィルター６を設けておくことが好ましい。   In order to prevent contact between the object to be measured and the object to be measured and the measuring unit 2 at the time of measurement, it is preferable to provide a protective filter 6 on the window 11 as shown in FIG.

防護フィルター６としては、計測に光度的・色彩的に影響を与えない無色透明の樹脂ないしはガラス製の如き板体、又は網体から形成する。尚、図２に示す態様では、網体を用いている。防護フィルター６が網体である場合、被計測物の大きさより小さな網目に形成することは勿論である。   The protective filter 6 is formed of a colorless transparent resin or a plate made of glass or a net that does not affect the measurement in terms of light and color. In the embodiment shown in FIG. 2, a net is used. Of course, when the protective filter 6 is a mesh, it is formed in a mesh smaller than the size of the object to be measured.

光源２１及び受光部２２から防護フィルター６までの距離は、計測時の測定可能焦点距離の少なくとも近接限界点以上、好ましくは測定可能焦点距離の最適距離近似点としておくことで、被計測物に防護フィルター６が接するようにした状態で計測すれば誤差の少ない計測値を得ることができる。   The distance from the light source 21 and the light receiving unit 22 to the protective filter 6 is at least the proximity limit point of the measurable focal length at the time of measurement, preferably the optimum distance approximation point of the measurable focal length, thereby protecting the object to be measured. If measurement is performed with the filter 6 in contact, a measurement value with less error can be obtained.

尚、本発明に係る測色計は、電源を電源コードを介して外部のコンセントから取る構成であってもよいし、或いは、交換式又は充電式バッテリーを本体１に内蔵する構成であってもよい。   The colorimeter according to the present invention may have a configuration in which the power source is taken from an external outlet via a power cord, or a configuration in which a replaceable or rechargeable battery is built in the main body 1. Good.

尚また、本発明に係る測色計は、計測部２及び窓部１１、表示部４、操作部５、本体１並びにグリップ部１２の各構成部材の位置や形状など、上記の実施例に限定されず、簡易的な測色計が採り得る位置や形状であれば、他の態様であってもよい。   In addition, the colorimeter according to the present invention is limited to the above-described embodiments, such as the position and shape of each component of the measurement unit 2, the window unit 11, the display unit 4, the operation unit 5, the main body 1, and the grip unit 12. Any other mode may be used as long as the position and shape can be taken by a simple colorimeter.

以上の構成を有する本発明に係る測色計の利用方法としては、例えば、布の染色時に所定の色具合まで染まっているかどうかの確認に利用することができる。予め、色見本等を計測しておき、該色見本の計測値を参考値として染め具合を計測しながら調整することで、所望の色に染色することが可能となる。   As a method of using the colorimeter according to the present invention having the above-described configuration, for example, it can be used for checking whether or not a predetermined color condition is dyed when dyeing a cloth. It is possible to dye a desired color by measuring a color sample in advance and adjusting it while measuring the dyeing condition using the measured value of the color sample as a reference value.

また、コーヒー豆の焙煎にも利用することができる。豆の種類（ブラジル、マンデリン、モカ等）やローストの種類（フレンチロースト、イタリアンロースト等）に応じて予め焙煎見本参照値を明示しておけば、焙煎時に豆を炒りながらその都度計測して焙煎見本参照値となるまで焙煎することで、未熟者であっても経験者の如き焙煎を行うことが可能となる。   It can also be used for roasting coffee beans. If you specify the roast sample reference value in advance according to the type of bean (Brazil, Mandelin, Mocha, etc.) or roast type (French roast, Italian roast, etc.), you can measure each time while roasting the beans By roasting until the roast sample reference value is reached, even an unskilled person can perform roasting like an experienced person.

更に、外壁塗装時に、所望の色具合に配合したペンキを計測することで、追加のペンキが必要になった際や日を置いてのペンキ配合時に、先の色具合と同じ配合のペンキを得ることが可能となる。   In addition, by measuring the paint blended in the desired color condition at the time of exterior wall painting, when adding paint when necessary or when blending the paint in the day, obtain the paint of the same composition as the previous color condition It becomes possible.

その他の利用例として、肌の色を計測する化粧品分野、内装工事（例えば、インテリアコーディネーターによるもの）等の色追跡、色による選別ないし判別、カラーマッチングの用途にも利用することができる。   As other application examples, the present invention can also be used in the cosmetics field for measuring skin color, color tracking in interior construction (for example, by an interior coordinator), sorting or discrimination by color, and color matching.

以上の利用例は、従来の厳密且つ精緻な色測定に適した高価な光学測定機器では明らかにオーバースペックであり、特に作業現場においては本発明に係る測色計の如き簡易な計測手段を用いることで充分対応可能である。   The above usage example is clearly over-spec in the expensive optical measuring instrument suitable for the strict and precise color measurement in the past, and a simple measuring means such as the colorimeter according to the present invention is used particularly at the work site. This is enough.
