Description

本発明は、例えば色、光沢などの所定の光学特性を測定する光学特性測定装置および測定装置置台に関する。 The present invention relates to an optical characteristic measuring device and a measuring device stand for measuring predetermined optical characteristics such as color and gloss.

従来から、色、光沢などの所定の光学特性を測定する光学特性測定装置は知られており、例えば特許文献１に、光学特性測定装置が開示されている。この特許文献１に開示された光学特性測定装置は、測定開口を有し、所定のジオメトリの光学系を用いることによって前記測定開口に臨む測定対象における光沢を測定する光学測定部を有する測定装置本体と、光沢の校正に用いられる校正基準部材とを備えたものである。校正基準部材は、校正基準板と、一端側を開口し、校正基準板を収納した保護カバー部とから構成されている。そして、測定対象の光沢測定に際し、まず、保護カバー部に一端側から校正基準板を収納して保護カバー部と校正基準板とが係止されることによって、保護カバー部に収納した校正基準板が測定装置本体の測定開口の周部の全周に当接して測定開口全体を覆う状態にされる。そして、その状態で、光学測定部によって校正基準板の光沢値が測定されて光沢基準値とされ、その光沢基準値に基いて測定対象の光沢度が算出される。 Conventionally, an optical characteristic measuring device for measuring a predetermined optical characteristic such as color and gloss has been known. For example, Patent Document 1 discloses an optical characteristic measuring device. The optical characteristic measuring device disclosed in Patent Document 1 has a measuring aperture, and is a measuring device main body having an optical measuring unit for measuring gloss in a measuring object facing the measuring aperture by using an optical system having a predetermined geometry. And a calibration reference member used for gloss calibration. The calibration reference member is composed of a calibration reference plate and a protective cover portion having an opening on one end side and accommodating the calibration reference plate. Then, when measuring the gloss of the measurement target, first, the calibration reference plate is stored in the protective cover portion from one end side, and the protective cover portion and the calibration reference plate are locked, so that the calibration reference plate stored in the protective cover portion is stored. Is in contact with the entire circumference of the measurement opening of the measuring device main body to cover the entire measurement opening. Then, in that state, the gloss value of the calibration reference plate is measured by the optical measuring unit and used as the gloss reference value, and the glossiness of the measurement target is calculated based on the gloss reference value.

ところで、前記特許文献１では、保護カバー部と測定装置本体とが完全に係止状態にならない状態で、光学測定部によって校正基準板の光沢値が測定される場合も起こり得る。保護カバー部と測定装置本体とが完全に係止状態にならない場合では、校正基準板が測定装置本体に対する所定の姿勢位置から傾いて測定装置本体における測定開口の周部の一部とのみ当接して校正基準板と測定装置本体の測定開口の周部との間に隙間が生じた状態になり、校正基準板の光沢値にバラツキが生じる虞がある。したがって、前記特許文献１では、校正基準板の光沢値が変動してしまい、再現性が低く、校正の精度が低くなる虞があり、その結果、測定対象の光沢度の精度が低くなってしまう。 By the way, in Patent Document 1, the gloss value of the calibration reference plate may be measured by the optical measuring unit in a state where the protective cover unit and the measuring device main body are not completely locked. If the protective cover and the measuring device body are not completely locked, the calibration reference plate tilts from the predetermined posture position with respect to the measuring device body and comes into contact with only a part of the peripheral portion of the measuring opening in the measuring device body. As a result, a gap may be formed between the calibration reference plate and the peripheral portion of the measurement opening of the measuring device main body, and the gloss value of the calibration reference plate may vary. Therefore, in Patent Document 1, the gloss value of the calibration reference plate fluctuates, the reproducibility is low, and the calibration accuracy may be low. As a result, the glossiness of the measurement target is low. ..

校正基準部材３２は、光沢校正用の円板状の校正基準板３２１ａと、校正基準板３２１ａを保持する保持部材３２２とを備えている。 The calibration reference member 32 includes a disk-shaped calibration reference plate 321a for gloss calibration and a holding member 322 for holding the calibration reference plate 321a.

校正基準板３２１ａは、測定開口形成部材１２７の測定開口１３０よりも径が大きく、測定開口形成部材１２７の測定開口１３０の周縁全体に当接可能な大きさの部材である。 The calibration reference plate 321a is a member having a diameter larger than that of the measurement opening 130 of the measurement opening forming member 127 and having a size capable of contacting the entire peripheral edge of the measurement opening 130 of the measurement opening forming member 127.

保持部材３２２は、その上部側に校正基準板３２１ａを保持する基準板保持部３２３を備える。この基準板保持部３２３は、校正基準板３２１ａを下方側から受ける受け板３２４と、受け板３２４を囲むように受け板３２４の外周縁から上方に延ばされた周壁３２５とを備えており、基準板保持部３２３に保持された校正基準板３２１ａの上面が露出するように（外部に臨むように）なっている。 The holding member 322 includes a reference plate holding portion 323 for holding the calibration reference plate 321a on the upper side thereof. The reference plate holding portion 323 includes a receiving plate 324 that receives the calibration reference plate 321a from the lower side, and a peripheral wall 325 that extends upward from the outer peripheral edge of the receiving plate 324 so as to surround the receiving plate 324.

このように構成された校正基準部材３２は、校正基準板３２１ａを保持部材３２２で保持した状態で、置台ハウジング２１内において、測定開口形成部材嵌挿部３１の下部側に、下方側から突出するとともに、測定開口形成部材嵌挿部３１内を上下移動可能に配置されている。したがって、測定開口形成部材１２７が測定開口形成部材嵌挿部３１に嵌挿されると、測定開口形成部材１２７と校正基準板３２１ａの上面とが当接するようになっている。 The calibration reference member 32 configured in this way projects from the lower side to the lower side of the measurement opening forming member fitting portion 31 in the pedestal housing 21 in a state where the calibration reference plate 321a is held by the holding member 322. At the same time, the measurement opening forming member fitting portion 31 is arranged so as to be movable up and down. Therefore, when the measurement opening forming member 127 is fitted into the measuring opening forming member fitting portion 31, the measurement opening forming member 127 and the upper surface of the calibration reference plate 321a come into contact with each other.

校正基準部材３２が置台ハウジング２１内に配置された状態で、保持部材３２２の受け板３２４の凹部３２６は、測定開口形成部材嵌挿部３１の略中心に配置され、測定開口形成部材嵌挿部３１に嵌挿された測定開口形成部材１２７における測定開口１３０の略中心に位置するようになっている。 With the calibration reference member 32 arranged in the pedestal housing 21, the recess 326 of the receiving plate 324 of the holding member 322 is arranged substantially in the center of the measurement opening forming member fitting portion 31, and the measuring opening forming member fitting portion is inserted. It is located at substantially the center of the measurement opening 130 in the measurement opening forming member 127 fitted in the 31.

押圧機構３３は、押圧板３３１と、押圧板３３１を付勢するコイルばね（付勢部材）３３２とを備える。 The pressing mechanism 33 includes a pressing plate 331 and a coil spring (urging member) 332 that urges the pressing plate 331.

押圧板３３１は、円板状の本体部３３３と、校正基準部材３２の校正基準板３２１ａに当接する当接部（被係合部）３３４とを備える。 The pressing plate 331 includes a disk-shaped main body portion 333 and an abutting portion (engaged portion) 334 that abuts on the calibration reference plate 321a of the calibration reference member 32.

当接部３３４は、この実施形態では、本体部３３３の中心部に、本体部３３３と一体的に、本体部３３３から上方に突設された突出部から構成されている。この実施形態の当接部３３４は、円柱部の先端に、保持部材３２２の凹部３２６に嵌合して係合可能な半球面（曲面）に形成されている。 In this embodiment, the contact portion 334 is composed of a protruding portion projecting upward from the main body portion 333 integrally with the main body portion 333 at the central portion of the main body portion 333. The contact portion 334 of this embodiment is formed at the tip of the cylindrical portion into a hemispherical surface (curved surface) that can be fitted and engaged with the recess 326 of the holding member 322.

押圧板３３１は、当接部３３４が保持部材３２２の凹部３２６に嵌合した状態で、保持部材３２２の下方側に配設されている。 The pressing plate 331 is arranged on the lower side of the holding member 322 in a state where the contact portion 334 is fitted in the recess 326 of the holding member 322.

コイルばね３３２は、押圧板３３１の下方側に配設され、コイルばね３３２の上端が押圧板３３１の下面に係止され、コイルばね３３２の下端が置台ハウジング２１に係止されることにより、コイルばね３３２は、押圧板３３１を上方側に付勢している。これにより、押圧板３３１の当接部３３４を介して保持部材３２２の略中心部が、上方に付勢されている。 The coil spring 332 is arranged on the lower side of the pressing plate 331, the upper end of the coil spring 332 is locked to the lower surface of the pressing plate 331, and the lower end of the coil spring 332 is locked to the pedestal housing 21. The spring 332 urges the pressing plate 331 upward. As a result, the substantially central portion of the holding member 322 is urged upward via the contact portion 334 of the pressing plate 331.

上述のように測定開口形成部材１２７が測定開口形成部材嵌挿部３１に嵌挿されると、上述のように測定開口形成部材１２７と校正基準板３２１ａの上面とが当接するが、この付勢によって、その当接した校正基準板３２１ａの上面が、測定開口形成部材１２７に押し付けられる。 When the measurement opening forming member 127 is fitted into the measuring opening forming member fitting portion 31 as described above, the measuring opening forming member 127 and the upper surface of the calibration reference plate 321a come into contact with each other as described above. The upper surface of the calibration reference plate 321a that is in contact with the measurement reference plate 321a is pressed against the measurement opening forming member 127.

第２校正部３ｂは、色彩校正用の校正基準板３２１ｂが用いられている点で、光沢校正用の校正基準板３２１ａが用いられている第１校正部３ａと異なる。第２校正部３ｂにおけるそれ以外の構成は、第１校正部３ａと同構成を採っている。なお、色彩校正用の校正基準板３２１ｂは、光沢校正用の校正基準板３２１ａと同形状である。 The second calibration unit 3b is different from the first calibration unit 3a in that the calibration reference plate 321b for color calibration is used, and the calibration reference plate 321a for gloss calibration is used. Other configurations in the second calibration unit 3b are the same as those in the first calibration unit 3a. The calibration reference plate 321b for color calibration has the same shape as the calibration reference plate 321a for gloss calibration.

ゼロ校正部４は、図４に示すように、置台ハウジング２１の上壁２１１に形成されたゼロ校正用の測定開口形成部材嵌挿部４１と、そのゼロ校正用の測定開口形成部材嵌挿部４１と置台ハウジング２１の内部とを連通する連通孔４２とを備えており、この第２測定開口形成部材嵌挿部４１に測定開口形成部材１２７が嵌挿された状態で、測定装置本体１００が所定の操作をされることで光学特性測定部をゼロ校正できるようになっている。 As shown in FIG. 4, the zero calibration unit 4 includes a measurement opening forming member fitting portion 41 for zero calibration and a measuring opening forming member fitting portion for zero calibration formed on the upper wall 211 of the stand housing 21. The measuring device main body 100 is provided with a communication hole 42 for communicating the 41 and the inside of the pedestal housing 21, and the measuring opening forming member 127 is fitted into the second measuring opening forming member fitting portion 41. The optical characteristic measurement unit can be zero-calibrated by performing a predetermined operation.

なお、光沢校正および色彩校正を実施しない場合、図４に示すように、第１校正部３ａおよび第２校正部３ｂそれぞれの校正基準板３２１ａ、３２１ｂは、保護カバー３２８が被せられ、これによって、校正基準板３２１ａ、３２１ｂに埃等の付着の防止や、校正基準板３２１ａ、３２１ｂに他のものが当たることによる損傷の防止等が可能となっている。 When gloss calibration and color calibration are not performed, as shown in FIG. 4, the calibration reference plates 321a and 321b of the first calibration section 3a and the second calibration section 3b are covered with a protective cover 328, whereby the protective cover 328 is covered. It is possible to prevent dust and the like from adhering to the calibration reference plates 321a and 321b, and to prevent damage caused by hitting the calibration reference plates 321a and 321b with other objects.

次に、この実施形態の光学特性測定装置１の校正の動作について説明する。図６は、前記測定装置置台に設けられた第１校正部に測定装置本体に設けられた測定開口形成部材を嵌挿した状態の要部の拡大断面図である。図７は、図６の状態で、第１校正部に設けられた校正基準板に光を当てた際の説明図である。図８は、比較例における校正部の校正基準板に光を当てた際の説明図である。図９は、実施形態の測定装置置台と比較例の測定装置置台とのそれぞれの校正基準板の光学特性値（光沢値）を測定したデータをグラフに表した図である。 Next, the operation of calibrating the optical characteristic measuring device 1 of this embodiment will be described. FIG. 6 is an enlarged cross-sectional view of a main part in a state where a measurement opening forming member provided in the measuring device main body is fitted in the first calibration unit provided in the measuring device stand. FIG. 7 is an explanatory view when light is applied to the calibration reference plate provided in the first calibration unit in the state of FIG. FIG. 8 is an explanatory diagram when light is applied to the calibration reference plate of the calibration unit in the comparative example. FIG. 9 is a graph showing data obtained by measuring the optical characteristic values (gloss values) of the respective calibration reference plates of the measuring device stand of the embodiment and the measuring device stand of the comparative example.

光沢測定する際の校正を行う場合、ユーザは、第１校正部３ａの保護カバー３２８を外し、図６に示すように測定装置本体１００の測定開口形成部材１２７を測定装置置台２の測定開口形成部材嵌挿部３１に嵌挿する。その際、測定開口形成部材嵌挿部３１の周壁の内周が、測定開口形成部材１２７をガイドし、測定開口形成部材１２７が、円滑に測定開口形成部材嵌挿部３１内に入り込む。 When performing calibration when measuring gloss, the user removes the protective cover 328 of the first calibration unit 3a, and as shown in FIG. 6, the measurement opening forming member 127 of the measuring device main body 100 is used to form the measuring opening of the measuring device stand 2. It is fitted and inserted into the member fitting portion 31. At that time, the inner circumference of the peripheral wall of the measuring opening forming member fitting portion 31 guides the measuring opening forming member 127, and the measuring opening forming member 127 smoothly enters the measuring opening forming member inserting portion 31.

測定開口形成部材１２７が測定開口形成部材嵌挿部３１内に入り込んでいくと、測定開口形成部材１２７の下面（外面）が、光沢校正用の校正基準板３２１ａに当接し、更に、測定開口形成部材１２７が測定開口形成部材嵌挿部３１内に押し込まれると、測定開口形成部材１２７が、光沢校正用の校正基準板３２１ａをコイルばね３３２の付勢力に抗して押し下げた状態で嵌挿される。 When the measurement opening forming member 127 enters the measurement opening forming member fitting portion 31, the lower surface (outer surface) of the measuring opening forming member 127 abuts on the calibration reference plate 321a for gloss calibration, and further, the measurement opening is formed. When the member 127 is pushed into the measuring opening forming member fitting portion 31, the measuring opening forming member 127 is fitted and inserted in a state where the calibration reference plate 321a for gloss calibration is pushed down against the urging force of the coil spring 332. ..

したがって、測定開口形成部材１２７が測定開口形成部材嵌挿部３１内に嵌挿された状態で、測定開口形成部材１２７の下面（外面）に光沢校正用の校正基準板３２１ａがコイルばね３３２の付勢力によって押し付けられた状態になる。 Therefore, with the measurement opening forming member 127 fitted in the measuring opening forming member fitting portion 31, a calibration reference plate 321a for gloss calibration is attached to the lower surface (outer surface) of the measuring opening forming member 127 with the coil spring 332. It will be in a state of being pressed by the forces.

その際、コイルばね３３２が押圧板３３１の当接部３３４および保持部材３２２を介して校正基準板３２１ａを、測定開口形成部材１２７における測定開口１３０の中心部に当たる部分で押圧するため、コイルばね３３２の付勢力が、測定開口形成部材１２７における測定開口１３０の周部の全体に略均等にかかる。 At that time, the coil spring 332 presses the calibration reference plate 321a via the contact portion 334 and the holding member 322 of the pressing plate 331 at the portion corresponding to the central portion of the measurement opening 130 in the measurement opening forming member 127, so that the coil spring 332 The urging force of the above is applied substantially evenly to the entire peripheral portion of the measurement opening 130 in the measurement opening forming member 127.

例えば、比較例では、図８に示すように、バネで校正基準板３２１ａの端を押圧する場合、図８に示すように、光沢校正用の校正基準板３２１ａが測定開口形成部材１２７に対して所定位置から傾いて測定開口１３０の周部の一部と光沢校正用の校正基準板３２１ａとの間に隙間ｔが、生じ易くなる。したがって、この場合では、光沢校正用の校正基準板３２１ａの光沢測定値にバラツキが生じる虞れがあり、光沢校正用の校正基準板３２１ａの光沢値を正確に再現し難く、精度の高い校正を行い難い。 For example, in the comparative example, when the end of the calibration reference plate 321a is pressed by a spring as shown in FIG. 8, the calibration reference plate 321a for gloss calibration is applied to the measurement opening forming member 127 as shown in FIG. A gap t is likely to occur between a part of the peripheral portion of the measurement opening 130 tilted from a predetermined position and the calibration reference plate 321a for gloss calibration. Therefore, in this case, the gloss measurement value of the calibration reference plate 321a for gloss calibration may vary, and it is difficult to accurately reproduce the gloss value of the calibration reference plate 321a for gloss calibration, so that highly accurate calibration can be performed. Difficult to do.

一方、本実施形態では、コイルばね３３２の付勢力が測定開口形成部材１２７における測定開口１３０の周部の全体に略均等にかかるため、図７に示すように、光沢校正用の校正基準板３２１ａが測定開口形成部材１２７に対して傾くことなく、より確実に、所定位置に配置され、測定開口１３０の周部の全体が光沢校正用の校正基準板３２１ａに当接し、測定開口１３０の周部と光沢校正用の校正基準板３２１ａとの間に隙間が生じ難くなる。したがって、光沢校正用の校正基準板３２１ａの光沢値にバラツキが生じる虞れが少なく、より確実に、光沢校正用の校正基準板３２１ａの光沢値を正確に再現でき、精度の高い校正ができる。 On the other hand, in the present embodiment, the urging force of the coil spring 332 is applied substantially evenly to the entire peripheral portion of the measurement opening 130 in the measurement opening forming member 127. Therefore, as shown in FIG. 7, the calibration reference plate 321a for gloss calibration is applied. Is more reliably arranged in a predetermined position without tilting with respect to the measurement opening forming member 127, and the entire peripheral portion of the measurement opening 130 comes into contact with the calibration reference plate 321a for gloss calibration, and the peripheral portion of the measurement opening 130 A gap is less likely to occur between the surface and the calibration reference plate 321a for gloss calibration. Therefore, there is little possibility that the gloss value of the calibration reference plate 321a for gloss calibration will vary, and the gloss value of the calibration reference plate 321a for gloss calibration can be reproduced more reliably, and highly accurate calibration can be performed.

ここで、光沢校正用の校正基準板３２１ａの光沢値について、本実施形態の光学特性測定装置１と、図８に示す比較例とのそれぞれについて、比較試験が実施されたので、以下に説明する。 Here, regarding the gloss value of the calibration reference plate 321a for gloss calibration, a comparative test was carried out for each of the optical characteristic measuring device 1 of the present embodiment and the comparative example shown in FIG. 8, which will be described below. ..

比較試験は、本実施形態の光学特性測定装置１（本実施形態品）と、図８に示す比較例とのそれぞれについて、光沢校正用の校正基準板３２１ａの光沢値を、その都度脱着しながら２０回、測定し、それぞれの光沢値について、各１回目に測定した光沢値に対する差を求めることにより実施された。図９の横軸は、測定回数であり、その縦軸は、１回目の測定値との差である。 In the comparative test, the gloss value of the calibration reference plate 321a for gloss calibration is attached and detached each time for each of the optical characteristic measuring device 1 (the product of the present embodiment) of the present embodiment and the comparative example shown in FIG. It was measured 20 times, and for each gloss value, the difference from the gloss value measured at the first time was obtained. The horizontal axis of FIG. 9 is the number of measurements, and the vertical axis thereof is the difference from the first measured value.

その結果は、図９に示すように、本実施形態品による光沢値の差は、比較例の場合よりもバラツキが小さくなることが確認できた。 As a result, as shown in FIG. 9, it was confirmed that the difference in gloss value between the products of the present embodiment was smaller than that in the case of the comparative example.

色彩測定する際の校正を行う場合も、ユーザは、上述の光沢の校正の場合と同様に、第２校正部３ｂの保護カバー３２８を外し、測定装置本体１００の測定開口形成部材１２７を測定装置置台２の測定開口形成部材嵌挿部３１に嵌挿する。その場合においても、測定開口形成部材嵌挿部３１の周壁の内周が、測定開口形成部材１２７をガイドし、測定開口形成部材１２７が、円滑に測定開口形成部材嵌挿部３１内に入り込む。 When performing calibration at the time of color measurement, the user removes the protective cover 328 of the second calibration unit 3b and measures the measurement opening forming member 127 of the measuring device main body 100 as in the case of the gloss calibration described above. It is fitted and inserted into the measurement opening forming member fitting portion 31 of the stand 2. Even in that case, the inner circumference of the peripheral wall of the measuring opening forming member fitting portion 31 guides the measuring opening forming member 127, and the measuring opening forming member 127 smoothly enters the measuring opening forming member fitting portion 31.

測定開口形成部材１２７が測定開口形成部材嵌挿部３１内に入り込んで嵌挿された状態で、測定開口形成部材１２７に色彩校正用の校正基準板３２１ｂがコイルばね３３２の付勢力によって押し付けられた状態になる。 A calibration reference plate 321b for color calibration was pressed against the measurement opening forming member 127 by the urging force of the coil spring 332 in a state where the measuring opening forming member 127 was inserted into the measuring opening forming member fitting portion 31 and inserted. Become in a state.

その場合においても、コイルばね３３２が押圧板３３１の当接部３３４および保持部材３２２を介して校正基準板３２１ｂを、測定開口形成部材１２７における測定開口１３０の中心部に当たる部分で押圧するため、コイルばね３３２の付勢力が、測定開口形成部材１２７における測定開口１３０の周部の全体に略均等にかかる。これにより、色彩校正用の校正基準板３２１ｂが、測定開口形成部材１２７に対して傾くことなく、より確実に、所定位置に配置され、測定開口１３０の周部の全体が、色彩校正用の校正基準板３２１ｂに当接し、測定開口１３０の周部と色彩校正用の校正基準板３２１ｂとの間に隙間が、生じ難くなる。したがって、色彩校正用の校正基準板３２１ｂの色彩値にバラツキが生じる虞れが少なく、色彩校正用の校正基準板３２１ｂの色彩校正値を正確に再現でき、精度の高い校正ができる。 Even in that case, since the coil spring 332 presses the calibration reference plate 321b via the contact portion 334 and the holding member 322 of the pressing plate 331 at the portion corresponding to the central portion of the measurement opening 130 in the measurement opening forming member 127, the coil. The urging force of the spring 332 is applied substantially evenly to the entire peripheral portion of the measurement opening 130 in the measurement opening forming member 127. As a result, the calibration reference plate 321b for color calibration is more reliably arranged at a predetermined position without being tilted with respect to the measurement opening forming member 127, and the entire peripheral portion of the measurement opening 130 is calibrated for color calibration. It comes into contact with the reference plate 321b, and a gap is less likely to occur between the peripheral portion of the measurement opening 130 and the calibration reference plate 321b for color calibration. Therefore, there is little possibility that the color value of the calibration reference plate 321b for color calibration will vary, and the color calibration value of the calibration reference plate 321b for color calibration can be accurately reproduced, and highly accurate calibration can be performed.

図１０は、前記測定装置置台の他の実施形態の要部の説明図である。図１１は、前記測定装置に設けられた測定開口形成部材の他の実施形態の断面図である。 FIG. 10 is an explanatory view of a main part of another embodiment of the measuring device stand. FIG. 11 is a cross-sectional view of another embodiment of the measurement opening forming member provided in the measuring device.

なお、上記実施形態では、保持部材３２２の受け板３２４に凹部３２６が設けられ、押圧板３３１に凹部３２６に嵌合する突出部からなる当接部３３４が設けられたが、この形態のものに限らず、例えば、図１０に示すように、保持部材３２２ａの受け板３２４ａに、受け板３２４ａから下方に突出する突出部３２６ａが設けられ、押圧板３３１ａにその突出部３２６ａが嵌合する凹部からなる当接部３３４ａが設けられても良く、適宜に変更できる。 In the above embodiment, the receiving plate 324 of the holding member 322 is provided with a recess 326, and the pressing plate 331 is provided with a contact portion 334 formed of a protruding portion that fits into the recess 326. Not limited to this, for example, as shown in FIG. 10, the receiving plate 324a of the holding member 322a is provided with a protruding portion 326a protruding downward from the receiving plate 324a, and the protruding portion 326a is fitted into the pressing plate 331a from a recess. The contact portion 334a may be provided, and can be appropriately changed.

また、上記実施形態では、コイルばね３３２は、上端の径が下端の径よりも小さいものであったが、コイルばね３３２は、特に限定されず、例えば図１０に示すように、例えば上端の径と下端の径とが略同じコイルばね３３２ａであっても良い。 Further, in the above embodiment, the diameter of the upper end of the coil spring 332 is smaller than the diameter of the lower end, but the coil spring 332 is not particularly limited, and for example, as shown in FIG. 10, the diameter of the upper end is, for example. The coil spring 332a may have substantially the same diameter at the lower end.

また、測定開口形成部材１２７における、校正に際して校正基準板３２１ａ、３２１ｂと対向する対向面となる外面（下面）１２８は、平面でも良いが、図１１に示すように、前記外面１２８は、測定開口１３０の少なくとも周辺領域において、測定開口１３０の周縁１２８ａに向かって（径方向内側に行くに従い）漸次外方（測定開口１３０の開口面における法線方向に沿った内側から外側に向かう方向）に突出し、かつ、前記測定開口１３０の周縁１２８ａが最も外方に突出する膨出形状またはテーパ形状に形成されても良い。このように構成することにより、測定開口形成部材１２７における測定開口１３０の周縁１２８ａ全体を、より確実に校正基準板３２１ａ、３２１ｂに当接させ易くできる。なお、測定開口形成部材１２７の外周端から測定開口１３０の周縁１２８ａまでの突出量は、例えば数μｍ程度でも良く、図１１では、測定開口形成部材１２７の外周端から測定開口１３０の周縁１２８ａまでの突出量が誇張して図示されている。 Further, the outer surface (lower surface) 128 of the measurement opening forming member 127, which is a facing surface facing the calibration reference plates 321a and 321b during calibration, may be a flat surface, but as shown in FIG. 11, the outer surface 128 is a measurement opening. In at least the peripheral region of 130, it gradually protrudes outward (from the inside to the outside along the normal direction in the opening surface of the measurement opening 130) toward the peripheral edge 128a of the measurement opening 130 (inward in the radial direction). In addition, the peripheral edge 128a of the measurement opening 130 may be formed in a bulging shape or a tapered shape that protrudes most outward. With this configuration, the entire peripheral edge 128a of the measurement opening 130 in the measurement opening forming member 127 can be more reliably brought into contact with the calibration reference plates 321a and 321b. The amount of protrusion from the outer peripheral end of the measurement opening forming member 127 to the peripheral edge 128a of the measurement opening 130 may be, for example, about several μm. In FIG. 11, from the outer peripheral end of the measurement opening forming member 127 to the peripheral edge 128a of the measurement opening 130. The amount of protrusion of is shown exaggerated.

また、上記実施形態では、測定装置本体１００は、光沢および色彩を測定できるものとされているが、例えば光沢と色彩とのいずれか一方を測定できるものであればよい。また、測定装置置台２も、光沢校正用の第１校正部３ａと色彩校正用の第２校正部３ｂとゼロ校正部４とを備えているが、光沢校正用の第１校正部３ａと色彩校正用の第２校正部３ｂとの少なくともいずれか一方を備えたものであれば良く、適宜に変更できる。 Further, in the above embodiment, the measuring device main body 100 is supposed to be capable of measuring gloss and color, but for example, it may be any as long as it can measure either gloss or color. Further, the measuring device stand 2 also includes a first calibration unit 3a for gloss calibration, a second calibration unit 3b for color calibration, and a zero calibration unit 4, but the first calibration unit 3a for gloss calibration and color. It suffices as long as it is provided with at least one of the second calibration unit 3b for calibration, and can be appropriately changed.

また、上記実施形態では、コイルばね３３２が用いられ、コイルばね３３２により、押圧板３３１の当接部３３４を保持部材３２２の略中心部を押圧することにより、校正基準部材３２は、測定開口形成部材１２７における測定開口１３０の略中央部に当たる部分で押圧されているが、この形態のものに限らず、例えば板バネが用いられ、前記板バネで、校正基準部材３２は、測定開口形成部材１２７における測定開口１３０の内側（内周側）に当たる部分で押圧されてよく、適宜に変更できる。 Further, in the above embodiment, the coil spring 332 is used, and the calibration reference member 32 forms a measurement opening by pressing the contact portion 334 of the pressing plate 331 against the substantially central portion of the holding member 322 by the coil spring 332. Although it is pressed at a portion of the member 127 that corresponds to a substantially central portion of the measurement opening 130, not limited to this form, for example, a leaf spring is used, and in the leaf spring, the calibration reference member 32 is the measurement opening forming member 127. It may be pressed at the portion corresponding to the inside (inner peripheral side) of the measurement opening 130 in the above, and can be appropriately changed.

また、上記実施形態では、押圧機構３３は、押圧板３３１とコイルばね３３２とを備えているが、例えば押圧機構３３は、コイルばね３３２のみから構成され、押圧板３３１を有さない形態のものでも良い。押圧機構３３がコイルばね３３２のみから構成され、コイルばね３３２の上端が校正基準部材３２に当接される場合において、コイルばね３３２の上端は、測定開口１３０の径よりも小さく、校正基準部材３２に対し、測定開口形成部材１２７における測定開口１３０の内側（内周側）に当たる部分に当接されればよい。 Further, in the above embodiment, the pressing mechanism 33 includes a pressing plate 331 and a coil spring 332. For example, the pressing mechanism 33 is composed of only the coil spring 332 and does not have the pressing plate 331. But it's okay. When the pressing mechanism 33 is composed of only the coil spring 332 and the upper end of the coil spring 332 is in contact with the calibration reference member 32, the upper end of the coil spring 332 is smaller than the diameter of the measurement opening 130, and the calibration reference member 32. On the other hand, it suffices to abut the portion of the measurement opening forming member 127 that corresponds to the inside (inner peripheral side) of the measurement opening 130.
