＊＊＊機能の説明＊＊＊
まず、レンズ部３１０のホルダー部３２０への装着方法に関して説明をする。
（１）はじめに、レンズユニット３００は、ホルダー部３２０の取付側開口３２６より、レンズ部３１０を出射部３１２側から挿し込みをする。
このとき、レンズ部３１０は、レンズ切欠部３１４ａにより、レンズ鍔部３１４と第２係止部３２２及び突出嵌合部３３０とが干渉しないで挿し込まれる。また、第２係止部３２２と突出嵌合部３３０とが直線状に配設されているので途中で引っ掛かることなく簡単に挿し込むことができる。
（２）レンズ部３１０のレンズ鍔部３１４がホルダー部３２０の第１係止部３２１に当接するまで挿し込んだあとに、レンズ部３１０を、レンズ鍔部３１４が第１係止部３２１を摺動するように回動させる。
レンズ部３１０は、レンズ鍔部３１４が第１係止部３２１と第２係止部３２２に挟まれ、ホルダー部３２０に装着される。
なお、レンズ部３１０をホルダー部３２０から取り外すには、装着時と逆の手順により取り外すことができる。
以上の手順により、図７に示すように、レンズ部３１０がホルダー部３２０に装着されたレンズユニット３００が完成する。 *** Description of functions ***
First, a method for attaching the lens unit 310 to the holder unit 320 will be described.
(1) First, the lens unit 300 inserts the lens part 310 from the emission part 312 side through the attachment side opening 326 of the holder part 320.
At this time, the lens part 310 is inserted by the lens notch part 314a without interference between the lens flange part 314, the second locking part 322, and the protruding fitting part 330. Moreover, since the 2nd latching | locking part 322 and the protrusion fitting part 330 are arrange | positioned linearly, it can insert easily, without being caught on the way.
(2) After inserting the lens portion 310 until the lens flange portion 314 of the lens portion 310 contacts the first locking portion 321 of the holder portion 320, the lens portion 310 and the lens flange portion 314 slide on the first locking portion 321. Rotate to move.
The lens portion 310 is attached to the holder portion 320 with the lens collar portion 314 sandwiched between the first locking portion 321 and the second locking portion 322.
In addition, in order to remove the lens part 310 from the holder part 320, it can remove by the reverse procedure to the time of mounting | wearing.
Through the above procedure, the lens unit 300 in which the lens unit 310 is mounted on the holder unit 320 is completed as shown in FIG.

次に、レンズユニット３００の器具本体部２００への装着方法に関して説明をする。
（１）レンズユニット３００は、図４の（ａ）に示すように、レンズ部３１０が器具本体部２００の側壁部２２０内側に、ホルダー部３２０が側壁部２２０の外側に配置されるように、器具本体部２００に挿し込まれる。このとき、突出嵌合部３３０は凹み嵌合部２４０に挿し込まれる。また、このとき第２係止部３２２は側壁切欠部２２２に配置される。
（２）レンズユニット３００は、第２係止部３２２が側壁切欠部２２２に配設されるとともに、突出嵌合部３３０が交差部２４３に配設されるまで挿し込まれた後に、突出嵌合部３３０を端部２４２へ回動させる。そして、突出嵌合部３３０は、凹み嵌合部２４０の端部２４２で保持される。このとき、第２係止部３２２は側壁切欠部２２２内を移動する。なお、突出嵌合部３３０が凹み嵌合部２４０の端部２４２で保持された状態でも側壁切欠部２２２に配設されたままである。 Next, a method for attaching the lens unit 300 to the instrument main body 200 will be described.
(1) As shown in FIG. 4A, the lens unit 300 is arranged such that the lens portion 310 is disposed inside the side wall portion 220 of the instrument main body portion 200 and the holder portion 320 is disposed outside the side wall portion 220. It is inserted into the instrument body 200. At this time, the protruding fitting portion 330 is inserted into the recessed fitting portion 240. At this time, the second locking portion 322 is disposed in the side wall notch portion 222.
(2) The lens unit 300 is protruded and fitted after the second locking portion 322 is disposed in the side wall notch portion 222 and inserted until the projecting fitting portion 330 is disposed in the intersecting portion 243. The part 330 is rotated to the end part 242. The protruding fitting portion 330 is held by the end portion 242 of the recessed fitting portion 240. At this time, the second locking part 322 moves in the side wall notch part 222. Even when the protruding fitting portion 330 is held by the end portion 242 of the recessed fitting portion 240, the protruding fitting portion 330 remains disposed in the side wall notch portion 222.

以上のように、凹み嵌合部２４０と突出嵌合部３３０とは嵌め合いされ、レンズユニット３００は器具本体部２００に装着される。
また、突出嵌合部３３０の回動によりスライド部３３４が水平側辺部２４２ａに沿って斜め上方向、すなわち斜めに取付側方向へ摺動することでホルダー部３２０の取付側開口３２６と器具本体部２００の正面縁部２１１とが密着する。さらに、側壁部２２０の開口縁部２２１が、レンズ鍔部３１４の押さえとなりレンズ部３１０の位置が移動してずれるのを防いでいる。
なお、レンズユニット３００を器具本体部２００からの取り外すには、装着時と逆の手順により取り外すことができる。 As described above, the recess fitting portion 240 and the protruding fitting portion 330 are fitted together, and the lens unit 300 is attached to the instrument main body portion 200.
Further, when the projecting fitting portion 330 is rotated, the slide portion 334 slides obliquely upward along the horizontal side portion 242a, that is, obliquely toward the attachment side, so that the attachment side opening 326 of the holder portion 320 and the instrument main body are slid. The front edge 211 of the part 200 is in close contact. Further, the opening edge portion 221 of the side wall portion 220 serves as a presser of the lens flange portion 314 and prevents the position of the lens portion 310 from moving and shifting.
In order to remove the lens unit 300 from the instrument main body 200, the lens unit 300 can be removed by a procedure reverse to that at the time of attachment.

次に、凹み嵌合部２４０と突出嵌合部３３０との嵌合方法に関して説明をする。
（１）突出嵌合部３３０を凹み嵌合部２４０の挿入部２４１より挿入し、第１配置部となる交差部２４３まで挿し込みをする。
このとき、突出嵌合部３３０は、第１傾斜部３３１が第１凸部２４４を摺動し交差部２４３に挿し込まれる。また、突出嵌合部３３０のスライド部３３４の照射側の部分が第１凸部２４４に係止され、突出嵌合部３３０が凹み嵌合部２４０の挿入部２４１から抜け難くなる。
（２）次に、レンズユニット３００を周方向に回動させ、突出嵌合部３３０を交差部２４３から第２配置部となる端部２４２へ移行させる。
このとき、突出嵌合部３３０の第２傾斜部３３２が第２凸部２４５を摺動し、突出嵌合部３３０が端部２４２へ移行され、突出嵌合部３３０は凹み嵌合部２４０と嵌合する。
なお、第２傾斜部３３２は第１傾斜部３３１より内角を大きく形成しており、第２傾斜部３３２を第２凸部２４５に摺動させる力は、第１傾斜部３３１を第２凸部２４５に摺動させる力よりも大きくなる。このように、第２傾斜部３３２は外れ難い傾斜角度に形成されており、意図せず第２傾斜部３３２が第２凸部２４５を交差部２４３の方向に摺動して外れるのを防ぐ。 Next, a method for fitting the recess fitting portion 240 and the protruding fitting portion 330 will be described.
(1) The protrusion fitting part 330 is inserted from the insertion part 241 of the dent fitting part 240, and is inserted to the intersection part 243 which becomes a 1st arrangement | positioning part.
At this time, the protrusion fitting part 330 is inserted into the intersecting part 243 with the first inclined part 331 sliding on the first convex part 244. Further, the irradiation side portion of the slide part 334 of the protrusion fitting part 330 is locked to the first convex part 244, and the protrusion fitting part 330 is difficult to be removed from the insertion part 241 of the concave fitting part 240.
(2) Next, the lens unit 300 is rotated in the circumferential direction, and the protruding fitting portion 330 is shifted from the intersecting portion 243 to the end portion 242 serving as the second arrangement portion.
At this time, the second inclined portion 332 of the protruding fitting portion 330 slides on the second convex portion 245, the protruding fitting portion 330 is moved to the end portion 242, and the protruding fitting portion 330 is connected to the recessed fitting portion 240. Mating.
The second inclined portion 332 has an inner angle larger than that of the first inclined portion 331, and the force that causes the second inclined portion 332 to slide on the second convex portion 245 causes the first inclined portion 331 to move to the second convex portion. It becomes larger than the force which makes 245 slide. Thus, the second inclined portion 332 is formed at an inclination angle that is difficult to come off, and prevents the second inclined portion 332 from unintentionally sliding off the second convex portion 245 in the direction of the intersecting portion 243.
