The accommodating portion 433 is formed with a ring-shaped concave portion 433 a that is recessed along the outer peripheral side and is provided along the inner periphery of the accommodating portion 433.
　固定部４４は、測定プローブ３の外径Ｄ３より小さい内径Ｄ４を有する挿入部４４１を有する。固定部４４は、弾性体、たとえばゴムやシリコンゴム等を用いて形成される。固定部４４は、収容部４２１の内径Ｄ１と略同一の外径を有する先端部４４２と、第２筒部４３の外径と同じ外径を有する基端部４４３と、を有する。先端部４４２および基端部４４３は、一体的に形成される。挿入部４４１は、測定プローブ３の先端部３３を挿入可能である。また、先端部４４２には、外周側に向けて突起し、先端部４４２の外周に沿って設けられたリング状をなす凸部４４２ａが形成されている。これにより、固定部４４は、第２筒部４３の凹部４３３ａに先端部４４２の凸部４４２ａが嵌合することで、第２筒部４３に着脱可能に固定される。 The fixing part 44 has an insertion part 441 having an inner diameter D4 smaller than the outer diameter D3 of the measurement probe 3.

Accordingly, the fixing portion 44 is detachably fixed to the second cylindrical portion 43 by fitting the convex portion 442a of the tip end portion 442 to the concave portion 433a of the second cylindrical portion 43.
　校正用部材４５は、円盤状をなす標準部材を用いて実現される。ここで、標準部材とは、白色板または表面が照明光に対して高い反射率を有する部材である。校正用部材４５は、光学測定装置２および測定プローブ３のキャリブレーション処理を行う際に測定プローブ３の先端から照射される照明光の照射対象となる。 The calibration member 45 is realized by using a standard member having a disk shape. Here, the standard member is a member whose white plate or surface has a high reflectance with respect to illumination light. The calibration member 45 is an irradiation target of illumination light emitted from the tip of the measurement probe 3 when the optical measurement device 2 and the measurement probe 3 are calibrated.
　付勢部材４６は、校正用部材４５を固定部４４に向けて付勢する。具体的には、付勢部材４６は、校正用部材４５を測定プローブ３の挿入方向（矢印Ｂ方向）に向けて付勢する。付勢部材４６は、圧縮バネ等を用いて実現される。付勢部材４６は、一端がベース部４１に接続され、他端が校正用部材４５に接続される。 The urging member 46 urges the calibration member 45 toward the fixed portion 44.

The urging member 46 is realized using a compression spring or the like. The urging member 46 has one end connected to the base portion 41 and the other end connected to the calibration member 45.
　スペーサー部４７は、測定プローブ３が挿入部４４１に挿入された際に、測定プローブ３の先端部３３と校正用部材４５との距離を一定に維持する。スペーサー部４７は、測定プローブ３の照明ファイバから照射される照明光が通過可能であるとともに、校正用部材４５で反射した照明光の戻り光が通過可能な孔部４７１を有する。スペーサー部４７は、遮光部材を用いて構成される。 The spacer portion 47 keeps the distance between the distal end portion 33 of the measurement probe 3 and the calibration member 45 constant when the measurement probe 3 is inserted into the insertion portion 441. The spacer portion 47 has a hole portion 471 through which illumination light emitted from the illumination fiber of the measurement probe 3 can pass and through which return light of the illumination light reflected by the calibration member 45 can pass. The spacer portion 47 is configured using a light shielding member.
　上述のように構成された光学測定システム１は、図４に示すように、内視鏡システム１００の内視鏡装置１１０（内視鏡スコープ）に設けられた処置具チャンネル１１１を介して測定プローブ３が挿入され、測定対象物に照明光を出射し、測定プローブ３の先端部３３から測定対象物で反射および／または散乱した照明光の戻り光を受光して受光部２４に出射する。その後、演算部２８１は、受光部２４の測定結果に基づいて、測定対象物の特性値を演算する。 As shown in FIG. 4, the optical measurement system 1 configured as described above includes a measurement probe via a treatment instrument channel 111 provided in an endoscope apparatus 110 (endoscope scope) of the endoscope system 100. 3 is inserted, emits illumination light to the measurement object, receives the return light of the illumination light reflected and / or scattered by the measurement object from the tip 33 of the measurement probe 3, and emits it to the light receiving unit 24. Thereafter, the calculation unit 281 calculates the characteristic value of the measurement object based on the measurement result of the light receiving unit 24.
　つぎに、光学測定システム１が実行するキャリブレーション処理の操作手順について説明する。図５Ａは、校正モジュール４に測定プローブ３が挿入される際の校正モジュール４の断面図である。図５Ｂは、校正モジュール４に測定プローブ３が挿入された直後の校正モジュール４の断面図である。図５Ｃは、校正モジュール４に測定プローブ３が挿入された後に操作者が測定プローブ３から手を離した際の校正モジュール４の断面図である。 Next, the operation procedure of the calibration process executed by the optical measurement system 1 will be described. FIG. 5A is a cross-sectional view of the calibration module 4 when the measurement probe 3 is inserted into the calibration module 4. FIG. 5B is a cross-sectional view of the calibration module 4 immediately after the measurement probe 3 is inserted into the calibration module 4. FIG. 5C is a cross-sectional view of the calibration module 4 when the operator releases the hand from the measurement probe 3 after the measurement probe 3 is inserted into the calibration module 4.
　図５Ａに示すように、まず、操作者は、測定プローブ３を校正モジュール４の固定部４４の挿入部４４１に挿入して、測定プローブ３の先端部３３がスペーサー部４７に接触するまで押し込む（図５Ａ→図５Ｂ）。この際、固定部４４の挿入部４４１は、測定プローブ３の挿入方向（矢印Ｂ方向）に沿って弾性変形する。 As shown in FIG. 5A, first, the operator inserts the measurement probe 3 into the insertion portion 441 of the fixing portion 44 of the calibration module 4 and pushes in until the distal end portion 33 of the measurement probe 3 comes into contact with the spacer portion 47 ( FIG. 5A → FIG. 5B). At this time, the insertion portion 441 of the fixing portion 44 is elastically deformed along the insertion direction (arrow B direction) of the measurement probe 3.
　続いて、操作者は、測定プローブ３を手から離す（図５Ｂ→図５Ｃ）。この場合、固定部４４は、弾性力によって元の形状に戻るため、測定プローブ３を測定プローブ３の挿入方向と逆向きに押し上げる。このとき、付勢部材４６は、校正用部材４５を固定部４４に向けて付勢しているので、スペーサー部４７および校正用部材４５が固定部４４に向けて移動する。この結果、測定プローブ３の先端部３３と校正用部材４５との距離を常に一定の状態に維持することができる。 Subsequently, the operator releases the measurement probe 3 from the hand (FIG. 5B → FIG. 5C). In this case, since the fixing portion 44 returns to the original shape by the elastic force, the measuring probe 3 is pushed up in the direction opposite to the insertion direction of the measurement probe 3. At this time, since the urging member 46 urges the calibration member 45 toward the fixed portion 44, the spacer portion 47 and the calibration member 45 move toward the fixed portion 44. As a result, the distance between the distal end portion 33 of the measurement probe 3 and the calibration member 45 can always be kept constant.
　その後、操作者は、入力部２５を操作することにより、光源部２２に照明光を出射させることにより、測定プローブ３の先端部３３から照明光を校正用部材４５に向けて照射させる。この際、校正処理部２８２は、受光部２４から入力される測定結果に基づいて、光学測定装置２および測定プローブ３のキャリブレーション処理を実行する。 Thereafter, the operator operates the input unit 25 to emit the illumination light to the light source unit 22, thereby irradiating the illumination light toward the calibration member 45 from the distal end portion 33 of the measurement probe 3. At this time, the calibration processing unit 282 executes calibration processing of the optical measurement device 2 and the measurement probe 3 based on the measurement result input from the light receiving unit 24.
　以上説明した本発明の実施の形態１によれば、付勢部材４６が固定部４４に向けて校正用部材４５を付勢するので、操作者が測定プローブ３から手を離した場合であっても、測定プローブ３の先端部３３が校正用部材４５と接触した状態を維持することができる。 According to the first embodiment of the present invention described above, the urging member 46 urges the calibration member 45 toward the fixed portion 44, so that the operator releases the hand from the measurement probe 3. In addition, the state in which the tip 33 of the measurement probe 3 is in contact with the calibration member 45 can be maintained.
　また、本発明の実施の形態１によれば、測定プローブ３が挿入部４４１に挿入された際に、スペーサー部４７が測定プローブ３の先端部３３と校正用部材４５との距離を一定に維持するので、正確なキャリブレーション処理を実行することができる。 Further, according to the first embodiment of the present invention, when the measurement probe 3 is inserted into the insertion portion 441, the spacer portion 47 keeps the distance between the distal end portion 33 of the measurement probe 3 and the calibration member 45 constant. Therefore, accurate calibration processing can be executed.
　また、本発明の実施の形態１によれば、スペーサー部４７または校正用部材４５が汚れた場合であっても、固定部４４を第２筒部４３から容易に取り外すことができ、他のスペーサー部４７または校正用部材４５に取り替えることができるので、コンタミネーションを防止することができる。 Further, according to Embodiment 1 of the present invention, even when the spacer portion 47 or the calibration member 45 is dirty, the fixing portion 44 can be easily detached from the second cylindrical portion 43, and other spacers Since the portion 47 or the calibration member 45 can be replaced, contamination can be prevented.
　また、本発明の実施の形態１によれば、校正モジュール４に液体等が浸入した場合であっても、第２筒部４３を第１筒部４２から容易に取り外すことができ、スペーサー部４７および校正用部材４５を含めて洗浄および消毒等を容易に行うことができる。 Further, according to the first embodiment of the present invention, even when a liquid or the like enters the calibration module 4, the second cylinder portion 43 can be easily detached from the first cylinder portion 42, and the spacer portion 47. In addition, cleaning and disinfection including the calibration member 45 can be easily performed.
　なお、本発明の実施の形態１では、付勢部材４６が校正用部材４５を固定部４４に向けて付勢していたが、付勢部材４６に換えて弾性部材を用いてよい。この場合、弾性部材が固定部４４に向けて校正用部材４５を付勢するので、操作者が測定プローブ３から手を離した場合であっても、測定プローブ３の先端部３３が校正用部材４５と接触した状態を維持することができる。 In the first embodiment of the present invention, the urging member 46 urges the calibration member 45 toward the fixed portion 44, but an elastic member may be used instead of the urging member 46. In this case, since the elastic member biases the calibration member 45 toward the fixed portion 44, the tip 33 of the measurement probe 3 remains the calibration member even when the operator releases the hand from the measurement probe 3.

　第１筒部５２は、略筒状をなす。第１筒部５２は、内部でスペーサー部４７、移動体５８および拡散板５９を測定プローブ３の挿入方向（矢印Ｂ）に沿って移動可能に収容する収容部５２１を有する。また、第１筒部５２は、円環部４２３が設けられている。 The first cylinder part 52 has a substantially cylindrical shape. The first cylinder part 52 includes an accommodating part 521 that accommodates the spacer part 47, the moving body 58 and the diffusion plate 59 so as to be movable along the insertion direction (arrow B) of the measurement probe 3. Further, the first tube portion 52 is provided with an annular portion 423.
　光源部５３は、光ファイバ５４を介して拡散板５９に照明光を出射する。光源部５３は、白色ＬＥＤを用いて構成される。 The light source unit 53 emits illumination light to the diffusion plate 59 via the optical fiber 54. The light source unit 53 is configured using a white LED.
　アダプタ部材５７は、筒状をなし、内部で光ファイバ５４を保持する本体部５７１と、本体部５７１から外周側に向けて延在して設けられ、移動体５８の凸部５８２に当接する係止部５７２と、を有する。本体部５７１の外周側には、移動体５８の凸部５８２の雌ネジ部５８２ａおよびスリーブ５６と螺合可能なネジ切りが施された雄ネジ部５７１ａが形成されている。これにより、アダプタ部材５７、移動体５８およびスリーブ５６は、一体的に測定プローブ３の挿入方向に沿って移動可能に収容部５２１に収容される。 The adapter member 57 has a cylindrical shape and is provided with a main body portion 571 that holds the optical fiber 54 therein, an extension extending from the main body portion 571 toward the outer peripheral side, and abutting against the convex portion 582 of the moving body 58.

Thereby, the adapter member 57, the moving body 58, and the sleeve 56 are accommodated in the accommodating part 521 so that it can move integrally along the insertion direction of the measurement probe 3.
　移動体５８は、略筒状をなし、内部でスペーサー部４７および拡散板５９を保持する収容部５８１を有する。収容部５８１は、中心に向けて突起した凸部５８２が設けられている。凸部５８２には、アダプタ部材５７の一部と螺合するためのネジ切りが施された雌ネジ部５８２ａが形成されている。 The moving body 58 has a substantially cylindrical shape, and has an accommodating portion 581 that holds the spacer portion 47 and the diffusion plate 59 therein. The accommodating portion 581 is provided with a convex portion 582 protruding toward the center. The convex portion 582 is formed with a female screw portion 582 a that is threaded to be screwed with a part of the adapter member 57.
　拡散板５９は、光ファイバ５４を介して光源部５３から出射された光の輝度ムラを緩和させて均一な光（一様な光）を透過させる。なお、本実施の形態２では、拡散板５９が校正用部材として機能する。 The diffuser plate 59 alleviates luminance unevenness of the light emitted from the light source unit 53 through the optical fiber 54 and transmits uniform light (uniform light). In the second embodiment, the diffusion plate 59 functions as a calibration member.
　付勢部材６０は、ベース部５１の収容部５１２に収容され、移動体５８を固定部４４に向けて付勢する。付勢部材６０は、コイルバネ等を用いて実現される。 The urging member 60 is accommodated in the accommodating portion 512 of the base portion 51 and urges the moving body 58 toward the fixed portion 44. The biasing member 60 is realized using a coil spring or the like.
　このように構成された校正モジュール５は、測定プローブ３が固定部４４の挿入部４４１に挿入されて測定プローブ３の先端部３３がスペーサー部４７に接触するまで押し込まれる。この場合、固定部４４は、元の形状に戻るため、測定プローブ３を挿入方向と逆向きに押し上げる。このとき、付勢部材６０は、移動体５８を固定部４４に向けて付勢する。これにより、測定プローブ３の先端部３３と拡散板５９との距離は、常に一定を維持した状態になる。 The calibration module 5 configured in this manner is pushed in until the measurement probe 3 is inserted into the insertion portion 441 of the fixing portion 44 and the tip portion 33 of the measurement probe 3 comes into contact with the spacer portion 47. In this case, since the fixing portion 44 returns to the original shape, the measuring probe 3 is pushed up in the direction opposite to the insertion direction. At this time, the urging member 60 urges the moving body 58 toward the fixed portion 44. Thereby, the distance between the distal end portion 33 of the measurement probe 3 and the diffusion plate 59 is always kept constant.
　以上説明した本発明の実施の形態２によれば、付勢部材６０が固定部４４に向けて拡散板５９を保持する移動体５８を付勢するので、操作者が測定プローブ３から手を離した場合であっても、測定プローブ３の先端部３３が拡散板５９と接触した状態を維持することができ、正確なキャリブレーション処理を実行することができる。 According to the second embodiment of the present invention described above, the urging member 60 urges the moving body 58 that holds the diffusing plate 59 toward the fixed portion 44, so that the operator releases the hand from the measurement probe 3. Even in this case, the state where the tip 33 of the measurement probe 3 is in contact with the diffusion plate 59 can be maintained, and an accurate calibration process can be executed.
