作業者は、引掛け溝２３２ａに指を引っ掛けて、両側の側部２３２を把持することにより、器具本体１００から光源部２００を簡単に、滑ることなく、取り外すことができる。なお、この引掛け溝２３２ａは、外殻部分に角部を形成すると、さらに指が引っ掛かり易くなり、より光源部２００を器具本体１００から取り外しやすくなる。   The operator can easily remove the light source unit 200 from the instrument main body 100 without slipping by hooking a finger on the hooking groove 232a and gripping the side portions 232 on both sides. In addition, if this hooking groove 232a forms a corner | angular part in an outer shell part, it will become easy to catch a finger | toe further and it will become easier to remove the light source part 200 from the instrument main body 100 more.

実施の形態２．
実施の形態２は、実施の形態１の側部２３２の変形例である。本実施の形態２において、実施の形態１と同様の構造については説明を省略し、本実施の形態２の特徴部分のみを説明する。図６は、実施の形態２の光源部２００の断面を示す断面図であり、図７は実施の形態２の照明器具１０００の断面を示す断面図である。図６、図７は、実施の形態１の図４、図５に対応する。 Embodiment 2. FIG.
The second embodiment is a modification of the side part 232 of the first embodiment. In the second embodiment, the description of the same structure as that of the first embodiment is omitted, and only the characteristic part of the second embodiment is described. FIG. 6 is a cross-sectional view showing a cross section of the light source unit 200 of the second embodiment, and FIG. 7 is a cross-sectional view showing a cross section of the lighting fixture 1000 of the second embodiment. 6 and 7 correspond to FIGS. 4 and 5 of the first embodiment.

実施の形態１の側部２３２は、透光性カバー２３０の外側から内側に向かって断面が滑らかに凹状に窪んで形成された引掛け溝２３２ａを有した。これに対して実施の形態２の側部２３２では、透光性カバー２３０の外側方向に凸状に突起して形成された、引掛け凸部２３２ｂを有する。引掛け凸部２３２ｂは、引掛け溝２３２ａと同様に透光性カバー２３０の長手方向にわたって形成されている。図６、図７において左側の側部２３２を第１の側部２３２とし、右側の側部２３２を第２の側部２３２とする。第１の側部２３２の引掛け凸部２３２ｂは第１側凸部であり第２の側部２３２の引掛け凸部２３２ｂは第２側凸
部である。 The side part 232 of the first embodiment has a hooking groove 232a formed so that the cross section is smoothly recessed in a concave shape from the outside to the inside of the translucent cover 230. On the other hand, the side part 232 of the second embodiment has a hooking convex part 232b formed by protruding in a convex shape in the outer direction of the translucent cover 230. The hooking convex part 232b is formed over the longitudinal direction of the translucent cover 230 similarly to the hooking groove 232a. 6 and 7, the left side 232 is referred to as a first side 232, and the right side 232 is referred to as a second side 232. The hook convex portion 232b of the first side portion 232 is a first side convex portion, and the hook convex portion 232b of the second side portion 232 is a second side convex portion.

引掛け溝２３２ａの場合と同様に、作業差は、引掛け凸部２３２ｂに指を引掛けるようにして、透光性カバー２３０の両側に設けられる側部２３２を把持することにより、器具本体１００から光源部２００を容易に取り外すことができる。なお、この引掛け凸部２３２ｂも、外殻部分に角部を形成してもよい。   As in the case of the hooking groove 232a, the work difference is determined by gripping the side portions 232 provided on both sides of the translucent cover 230 so that the finger is hooked on the hooking convex portion 232b. The light source unit 200 can be easily removed from the projector. In addition, this hooking convex part 232b may also form a corner | angular part in an outer shell part.

なお、実施の形態１の引掛け溝２３２ａ及び実施の形態２の引掛け凸部２３２ｂは、透光性カバー２３０の長手方向の全長にわたって形成される場合を説明したが一例である。引掛け溝２３２ａや引掛け凸部２３２ｂは、長手方向の全長にわたって形成されなくてもない。透光性カバー２３０の長手方向に部分的に形成されても構わない。   In addition, although the case where the hook groove 232a of Embodiment 1 and the hook convex part 232b of Embodiment 2 were formed over the full length of the longitudinal direction of the translucent cover 230 was demonstrated, it is an example. The hook groove 232a and the hook protrusion 232b may not be formed over the entire length in the longitudinal direction. It may be partially formed in the longitudinal direction of the translucent cover 230.

また、実施の形態１では引掛け溝部を説明し、実施の形態２では引掛け突部を説明したが、引掛け溝部と引掛け突部との両方を形成しても構わない。   Moreover, although the hook groove part was demonstrated in Embodiment 1, and the hook protrusion was demonstrated in Embodiment 2, you may form both a hook groove part and a hook protrusion.
