そのため、請求項4に記載の照明装置(30)によれば、光源(1)および概略棒状の光源支持部材(3)を回転させることなく、導光レンズ(2)、遮光部材(5)および筒状部材(4,6)を回転させることができる。その結果、請求項4に記載の照明装置(30)によれば、光源(1)が導光レンズ(2)、遮光部材(5)および筒状部材(4,6)と共に回転せしめられる場合よりも、光源(1)に対する電力供給の信頼性を向上させることができる。   Therefore, according to the illumination device (30) of claim 4, the light guide lens (2), the light shielding member (5) and the light source (1) and the substantially rod-shaped light source support member (3) are not rotated. The cylindrical members (4, 6) can be rotated. As a result, according to the illumination device (30) of the fourth aspect, the light source (1) is rotated together with the light guide lens (2), the light shielding member (5), and the cylindrical members (4, 6). In addition, the reliability of power supply to the light source (1) can be improved.

また、請求項4に記載の照明装置(30)によれば、光源(1)が概略棒状の光源支持部材(3)に搭載されていない場合よりも、光源(1)と導光レンズ(2)とを近接させることができ、その結果、光源(1)から照射されて導光レンズ(2)に入射する光の量を増加させることができる。   Moreover, according to the illuminating device (30) of Claim 4, rather than the case where the light source (1) is not mounted in the substantially rod-shaped light source support member (3), the light source (1) and the light guide lens (2). ), And as a result, the amount of light emitted from the light source (1) and incident on the light guide lens (2) can be increased.

請求項5に記載の照明装置(30)では、光源支持部材(3)と直線運動体前側板(10)とが接続されている。また、軸受部(7b)を有する軸受部材(7)と直線運動体前側板(10)とが接続されている。更に、直線運動体前側板(10)および直線運動体後側板(11)を概略光源(1)の光軸(1’)方向に移動可能にガイドするためのガイド部材(20a,20b,20c)と、直線運動体前側板(10)および直線運動体後側板(11)を概略光源(1)の光軸(1’)方向に移動させるための駆動手段(18)とが設けられている。   In the illumination device (30) according to claim 5, the light source support member (3) and the linear motion body front side plate (10) are connected. Moreover, the bearing member (7) which has a bearing part (7b), and the linear motion body front side plate (10) are connected. Further, guide members (20a, 20b, 20c) for guiding the linear motion body front side plate (10) and the linear motion body rear side plate (11) so as to be movable in the direction of the optical axis (1 ') of the light source (1). And a drive means (18) for moving the linear motion body front side plate (10) and the linear motion body rear side plate (11) in the direction of the optical axis (1 ') of the light source (1).

そのため、請求項5に記載の照明装置(30)によれば、概略光源(1)の光軸(1’)を中心に導光レンズ(2)と遮光部材(5)とを回転させることができると共に、光源(1)と導光レンズ(2)と遮光部材(5)とを概略光源(1)の光軸(1’)方向に移動させることができる。   Therefore, according to the illuminating device (30) according to claim 5, the light guide lens (2) and the light shielding member (5) can be rotated around the optical axis (1 ′) of the schematic light source (1). In addition, the light source (1), the light guide lens (2), and the light shielding member (5) can be moved in the direction of the optical axis (1 ′) of the light source (1).

その結果、請求項5に記載の照明装置(30)によれば、光源(1)と導光レンズ(2)と遮光部材(5)とを概略光源(1)の光軸(1’)方向に移動させることができない場合よりも、照明装置(30)の見え方(照明装置(30)の光り方)のバリエーションを増加させることができる。   As a result, according to the illumination device (30) of claim 5, the light source (1), the light guide lens (2), and the light shielding member (5) are arranged in the direction of the optical axis (1 ′) of the general light source (1). The variation in the appearance of the illumination device (30) (how the illumination device (30) shines) can be increased as compared to the case where the illumination device (30) cannot be moved.

請求項6に記載の照明装置(30)では、不動体前側板(14)に形成された軸受部(14a)によって筒状部材(4,6)が回転可能に支持される。換言すれば、請求項6に記載の照明装置(30)では、直線運動体前側板(10)に接続された軸受部材(7)の軸受部(7b)のみによって筒状部材(4,6)が回転可能に支持されるのではなく、直線運動体前側板(10)に接続された軸受部材(7)の軸受部(7b)と不動体前側板(14)に形成された軸受部(14a)とによって筒状部材(4,6)が回転可能に支持される。   In the illumination device (30) according to the sixth aspect, the cylindrical members (4, 6) are rotatably supported by the bearing portion (14a) formed on the non-moving object front side plate (14). In other words, in the illuminating device (30) according to claim 6, the cylindrical members (4, 6) are formed only by the bearing portion (7b) of the bearing member (7) connected to the linear motion body front side plate (10). Is not rotatably supported, but the bearing portion (14a) formed on the bearing portion (7b) of the bearing member (7) connected to the linear motion body front side plate (10) and the non-moving body front side plate (14). ) And the cylindrical member (4, 6) is rotatably supported.

つまり、請求項6に記載の照明装置(30)では、不動体前側板(14)に形成された軸受部(14a)が、筒状部材(4,6)を回転可能に支持する機能だけでなく、不動体前側板(14)に対して筒状部材(4,6)を概略光源(1)の光軸(1’)方向に移動可能にガイドする機能も有する。   That is, in the illumination device (30) according to claim 6, the bearing portion (14a) formed on the non-moving object front side plate (14) has only a function of rotatably supporting the cylindrical members (4, 6). And has a function of guiding the cylindrical members (4, 6) so as to be movable in the direction of the optical axis (1 ′) of the light source (1) with respect to the unmoving object front plate (14).

そのため、請求項6に記載の照明装置(30)によれば、不動体前側板(14)に対して筒状部材(4,6)を概略光源(1)の光軸(1’)方向に移動可能にガイドするための部材が不動体前側板(14)の軸受部(14a)とは別個に設けられている場合よりも、部品数を削減することができる。   Therefore, according to the illuminating device (30) of Claim 6, a cylindrical member (4, 6) is made to the optical axis (1 ') direction of a rough light source (1) with respect to an unmoving body front side plate (14). The number of parts can be reduced as compared with the case where the member for guiding the movement is provided separately from the bearing portion (14a) of the non-moving object front side plate (14).

軸受部材(7)の軸受部(7b)と、不動体前側板(14)の軸受部(14a)との同軸度を十分に高くしづらい場合には、仮に、不動体前側板(14)の軸受部(14a)の部分の板厚(t14a)が大きい値に設定されると、不動体前側板(14)の軸受部(14a)と筒状部材(4,6)との間で(図12中の位置Pで)こじりが生じてしまい、筒状部材(4,6)を概略光源(1)の光軸(1’)方向に円滑にガイドできなくなってしまうおそれがある。   If it is difficult to sufficiently increase the coaxiality between the bearing portion (7b) of the bearing member (7) and the bearing portion (14a) of the non-moving object front plate (14), it is assumed that the non-moving object front plate (14) When the plate thickness (t14a) of the portion of the bearing portion (14a) is set to a large value, the bearing portion (14a) of the non-moving object front side plate (14) and the cylindrical members (4, 6) (see FIG. 12 (position P in 12) may occur, and the cylindrical members (4, 6) may not be smoothly guided in the direction of the optical axis (1 ′) of the general light source (1).

この点に鑑み、請求項7に記載の照明装置(30)では、不動体前側板(14)のうち、軸受部(14a)以外の部分の板厚(t14)よりも、軸受部(14a)の部分の板厚(t14a)が小さい値に設定されている。   In view of this point, in the illumination device (30) according to claim 7, the bearing portion (14a) is larger than the plate thickness (t14) of the portion other than the bearing portion (14a) in the unmoving object front side plate (14). The plate thickness (t14a) of this part is set to a small value.

そのため、請求項7に記載の照明装置(30)によれば、不動体前側板(14)の軸受部(14a)と筒状部材(4,6)との間でこじりが生じてしまうおそれを低減することができる。   Therefore, according to the illuminating device (30) of Claim 7, there exists a possibility that a twist may arise between the bearing part (14a) of a stationary-body front side plate (14), and a cylindrical member (4, 6). Can be reduced.

請求項8に記載の照明装置(30)では、導光レンズ(2)の出射面(2c1,2c2)からの光を反射して照明装置(30)の照射方向に照射するために導光レンズ(2)の周囲に配列された複数の反射面(21a1,21a2,21a3,21a4,21a5,21a6,21a7,21a8,21a9,21a10,21a11,21a12,21a13,21a14,21a15,21a16,21a17,21a18,21a19,21a20,21a21,21a22,21a23,21a24,21a25,21a26,21a27,21a28,21a29,21a30,21a31,21a32,21a33,21a34,21a35,21a36)を有するリフレクタ(21)が設けられている。更に、相互に隣接する2つの反射面(21a1,21a2,21a3,21a4,21a5,21a6,21a7,21a8,21a9,21a10,21a11,21a12,21a13,21a14,21a15,21a16,21a17,21a18,21a19,21a20,21a21,21a22,21a23,21a24,21a25,21a26,21a27,21a28,21a29,21a30,21a31,21a32,21a33,21a34,21a35,21a36)が不連続な面によって形成されている。   In the illumination device (30) according to claim 8, the light guide lens for reflecting the light from the emission surface (2c1, 2c2) of the light guide lens (2) and irradiating it in the irradiation direction of the illumination device (30).

Furthermore, two reflecting surfaces (21a1, 21a2, 21a3, 21a4, 21a5, 21a6, 21a7, 21a8, 21a9, 21a10, 21a11, 21a12, 21a13, 21a14, 21a15, 21a16, 21a17, 21a18, 21a19, 21a20 , 21a21, 21a22, 21a23, 21a24, 21a25, 21a26, 21a27, 21a28, 21a29, 21a30, 21a31, 21a32, 21a33, 21a34, 21a35, 21a36).

そのため、請求項8に記載の照明装置(30)によれば、導光レンズ(2)を回転させることにより、照明装置(30)の照射方向から照明装置(30)を見た時に光って見える反射面(21a1,21a2,21a3,21a4,21a5,21a6,21a7,21a8,21a9,21a10,21a11,21a12,21a13,21a14,21a15,21a16,21a17,21a18,21a19,21a20,21a21,21a22,21a23,21a24,21a25,21a26,21a27,21a28,21a29,21a30,21a31,21a32,21a33,21a34,21a35,21a36)を変化させることができる。   Therefore, according to the illuminating device (30) of claim 8, by rotating the light guide lens (2), the illuminating device (30) is seen to shine when viewed from the irradiation direction of the illuminating device (30).

詳細には、第1の実施形態の照明装置30では、図3に示すように、導光レンズ2を隔てて光源1の反対側(図3の下側)に遮光部材5の本体部5aが配置されている。また、図5、図7および図9に示すように、遮光部材5の本体部5aから光源1の側(図5の左側)に延びている遮光部材5の脚部5b1,5b2,5b3,5b4が、遮光部材5の本体部5aの周方向に部分的に配置されている。更に、導光レンズ2の回転時に、導光レンズ2と一体的に遮光部材5が回転せしめられる。   In detail, in the illuminating device 30 of 1st Embodiment, as shown in FIG. 3, the main-body part 5a of the light-shielding member 5 is on the opposite side (lower side of FIG. 3) of the light source 1 across the light guide lens 2. As shown in FIG. Is arranged. As shown in FIGS. 5, 7 and 9, the legs 5b1, 5b2, 5b3 and 5b4 of the light shielding member 5 extending from the main body 5a of the light shielding member 5 toward the light source 1 (left side in FIG. 5). Are partially arranged in the circumferential direction of the main body 5a of the light shielding member 5. Further, when the light guide lens 2 is rotated, the light shielding member 5 is rotated integrally with the light guide lens 2.

更に、第1の実施形態の照明装置30では、導光レンズ2(図8および図11(A)参照)の出射面2c1,2c2(図7、図8および図11(A)参照)から出射した光の一部が、遮光部材5(図7および図9参照)の脚部5b1,5b2,5b3,5b4(図7および図9参照)によって遮られる。つまり、第1の実施形態の照明装置30では、導光レンズ2の出射面2c1,2c2から出射した光の残りの一部が、遮光部材5の脚部5b1,5b2,5b3,5b4によって遮られない。そのため、第1の実施形態の照明装置30によれば、導光レンズ2を回転させることによって照明装置30の見え方(照明装置30の光り方)を変化させることができる。   Furthermore, in the illuminating device 30 of 1st Embodiment, it radiate | emits from the output surfaces 2c1 and 2c2 (refer FIG. 7, FIG. 8 and FIG. 11 (A)) of the light guide lens 2 (refer FIG. 8 and FIG. 11 (A)). A portion of the light is blocked by the legs 5b1, 5b2, 5b3, 5b4 (see FIGS. 7 and 9) of the light blocking member 5 (see FIGS. 7 and 9). That is, in the illumination device 30 according to the first embodiment, the remaining part of the light emitted from the emission surfaces 2c1 and 2c2 of the light guide lens 2 is blocked by the legs 5b1, 5b2, 5b3, and 5b4 of the light shielding member 5. Absent. Therefore, according to the illumination device 30 of the first embodiment, the appearance of the illumination device 30 (how the illumination device 30 shines) can be changed by rotating the light guide lens 2.

詳細には、図8(D)に示す断面形状を光源1の光軸1’を中心に回転させることにより得られる回転体によって導光レンズ2が形成されている第5の実施形態の照明装置30であっても、導光レンズ2を回転させることによって照明装置30の見え方(照明装置30の光り方)を変化させることができる。   Specifically, the illumination device of the fifth embodiment in which the light guide lens 2 is formed by a rotating body obtained by rotating the cross-sectional shape shown in FIG. 8D around the optical axis 1 ′ of the light source 1. Even if it is 30, the appearance of the illumination device 30 (how the illumination device 30 shines) can be changed by rotating the light guide lens 2.

更に、第1の実施形態の照明装置30では、図11(A)に示すように、導光レンズ2が筒状部材4,6に接続されている。更に、筒状部材6を回転可能に支持するための軸受部7b,14aが、光源1を隔てて導光レンズ2の反対側(図11(A)の上側)に配置されている。そのため、第1の実施形態の照明装置30によれば、筒状部材4,6)を回転可能に支持するための軸受部7b,14aが光源1よりも導光レンズ2の側(図11(A)の下側)に配置されるのに伴って、光源1からの光の一部が軸受部7b,14aによって遮られてしまうおそれを排除することができる。つまり、第1の実施形態の照明装置30によれば、筒状部材4,6を回転可能に支持するための軸受部7b,14aが光源1よりも導光レンズ2の側(図11(A)の下側)に配置されている場合よりも、光源1からの光の利用効率を向上させることができる。   Furthermore, in the illuminating device 30 of 1st Embodiment, as shown to FIG. 11 (A), the light guide lens 2 is connected to the cylindrical members 4 and 6. FIG. Furthermore, bearing portions 7b and 14a for rotatably supporting the cylindrical member 6 are disposed on the opposite side of the light guide lens 2 (upper side in FIG. 11A) with the light source 1 therebetween. Therefore, according to the illuminating device 30 of 1st Embodiment, the bearing parts 7b and 14a for supporting the cylindrical members 4 and 6 rotatably are the light guide lens 2 side rather than the light source 1 (FIG. 11 (FIG. The possibility that a part of the light from the light source 1 is blocked by the bearing portions 7b and 14a as it is disposed on the lower side A) can be eliminated. That is, according to the illumination device 30 of the first embodiment, the bearing portions 7b and 14a for rotatably supporting the cylindrical members 4 and 6 are closer to the light guide lens 2 than the light source 1 (FIG. 11A). The utilization efficiency of light from the light source 1 can be improved as compared with the case where the light source 1 is disposed on the lower side.

また、第1の実施形態の照明装置30では、図3、図4および図5に示すように、光源1が概略棒状の光源支持部材3に搭載されている。更に、光源支持部材3が、筒状部材4,6と非接触の状態で筒状部材4,6の内部に配置されている。そのため、第1の実施形態の照明装置30によれば、光源1および概略棒状の光源支持部材3を回転させることなく、導光レンズ2、遮光部材5および筒状部材4,6を回転させることができる。その結果、第1の実施形態の照明装置30によれば、光源1が導光レンズ2、遮光部材5および筒状部材4,6と共に回転せしめられる場合よりも、光源1に対する電力供給の信頼性を向上させることができる。つまり、第1の実施形態の照明装置30では、例えば特開2008−16332号公報の図2に記載されているような可動(摺動式)接点を用いる必要がなく、また、光源1に対する電力供給するための配線が光源1の回転に伴って捩じれてしまうおそれもない。   Moreover, in the illuminating device 30 of 1st Embodiment, as shown in FIG.3, FIG4 and FIG.5, the light source 1 is mounted in the light source support member 3 of a substantially rod shape. Further, the light source support member 3 is disposed inside the cylindrical members 4 and 6 in a non-contact state with the cylindrical members 4 and 6.

Can be improved. That is, in the illumination device 30 according to the first embodiment, it is not necessary to use a movable (sliding) contact as described in FIG. 2 of Japanese Patent Application Laid-Open No. 2008-16332, for example. There is no possibility that the wiring for supply is twisted with the rotation of the light source 1.

また、第1の実施形態の照明装置30によれば、図3、図4および図5に示すように、光源1と導光レンズ2とを近接させることができ、その結果、光源1から照射されて導光レンズ(2)に入射する光の量を増加させることができる。   Moreover, according to the illuminating device 30 of 1st Embodiment, as shown in FIG.3, FIG4 and FIG.5, the light source 1 and the light guide lens 2 can be adjoined, As a result, it irradiates from the light source 1. Thus, the amount of light incident on the light guide lens (2) can be increased.

更に、第1の実施形態の照明装置30では、図4および図5に示すように、光源支持部材3と直線運動体前側板10とが接続されている。また、軸受部7bを有する軸受部材7と直線運動体前側板10とが接続されている。更に、図1および図6に示すように、直線運動体前側板10および直線運動体後側板11を概略光源1(図3参照)の光軸1’方向(図6の左右方向)に移動可能にガイドするためのガイド部材20a,20b,20cと、直線運動体前側板10および直線運動体後側板11を概略光源1の光軸1’方向に移動させるためのモータ18とが設けられている。そのため、第1の実施形態の照明装置30によれば、概略光源1の光軸1’を中心に導光レンズ2(図3参照)と遮光部材5とを回転させることができると共に、光源1と導光レンズ2と遮光部材5とを概略光源1の光軸1’方向(図6の左右方向)に移動させることができる。その結果、第1の実施形態の照明装置30によれば、光源1と導光レンズ2と遮光部材5とを概略光源1の光軸1’方向(図6の左右方向)に移動させることができない場合よりも、照明装置30の見え方(照明装置30の光り方)のバリエーションを増加させることができる。   Furthermore, in the illuminating device 30 of 1st Embodiment, as shown in FIG.4 and FIG.5, the light source support member 3 and the linear motion body front side board 10 are connected. Further, the bearing member 7 having the bearing portion 7b and the linear motion body front side plate 10 are connected. Furthermore, as shown in FIGS. 1 and 6, the linear motion body front side plate 10 and the linear motion body rear side plate 11 can be moved in the direction of the optical axis 1 ′ of the general light source 1 (see FIG. 3) (left and right direction in FIG. 6). Guide members 20a, 20b, and 20c for guiding the linearly moving body and the motor 18 for moving the linearly moving body front side plate 10 and the linearly moving body rear side plate 11 in the direction of the optical axis 1 ′ of the light source 1 are provided. . Therefore, according to the illumination device 30 of the first embodiment, the light guide lens 2 (see FIG. 3) and the light shielding member 5 can be rotated around the optical axis 1 ′ of the schematic light source 1 and the light source 1. The light guide lens 2 and the light shielding member 5 can be moved in the direction of the optical axis 1 ′ of the light source 1 (the left-right direction in FIG. 6). As a result, according to the illumination device 30 of the first embodiment, the light source 1, the light guide lens 2, and the light shielding member 5 can be moved in the direction of the optical axis 1 ′ of the light source 1 (the left-right direction in FIG. 6). Variations in how the illumination device 30 looks (how the illumination device 30 shines) can be increased as compared to when it is impossible.

また、第1の実施形態の照明装置30では、図1および図3に示すように、不動体前側板14に形成された軸受部14aによって筒状部材6が回転可能に支持される。換言すれば、第1の実施形態の照明装置30では、直線運動体前側板10に接続された軸受部材7の軸受部7bのみによって筒状部材6が回転可能に支持されるのではなく、直線運動体前側板10に接続された軸受部材7の軸受部7bと不動体前側板14に形成された軸受部14aとによって筒状部材6が回転可能に支持される。つまり、第1の実施形態の照明装置30では、不動体前側板14に形成された軸受部14aが、筒状部材6を回転可能に支持する機能だけでなく、不動体前側板14に対して筒状部材6を概略光源1の光軸1’方向(図3の上下方向)に移動可能にガイドする機能も有する。そのため、第1の実施形態の照明装置30によれば、不動体前側板14に対して筒状部材6を概略光源1の光軸1’方向(図3の上下方向)に移動可能にガイドするための部材が不動体前側板14の軸受部14aとは別個に設けられている場合よりも、部品数を削減することができる。   Moreover, in the illuminating device 30 of 1st Embodiment, as shown to FIG. 1 and FIG. 3, the cylindrical member 6 is rotatably supported by the bearing part 14a formed in the non-moving body front side plate 14. FIG. In other words, in the lighting device 30 of the first embodiment, the cylindrical member 6 is not rotatably supported only by the bearing portion 7b of the bearing member 7 connected to the linear moving body front side plate 10, but is linear. The cylindrical member 6 is rotatably supported by the bearing portion 7 b of the bearing member 7 connected to the moving body front side plate 10 and the bearing portion 14 a formed on the non-moving body front side plate 14. That is, in the illuminating device 30 of the first embodiment, the bearing portion 14a formed on the non-moving object front side plate 14 has not only a function of rotatably supporting the cylindrical member 6 but also the non-moving object front side plate 14. It also has a function of guiding the cylindrical member 6 so as to be movable in the direction of the optical axis 1 ′ of the light source 1 (up and down direction in FIG. 3). Therefore, according to the illuminating device 30 of 1st Embodiment, the cylindrical member 6 is guided with respect to the stationary body front plate 14 so that a movement to the optical axis 1 'direction (up-down direction of FIG. 3) of the light source 1 is possible. Therefore, the number of components can be reduced as compared with the case where the member for providing is provided separately from the bearing portion 14a of the unmoving object front side plate 14.

第1の実施形態の照明装置30のように、軸受部材7(図1参照)と不動体前側板14(図1参照)とが複数の部品を介して接続されており、軸受部材7の軸受部7b(図3参照)と、不動体前側板14の軸受部14a(図3参照)との同軸度を十分に高くしづらい場合には、仮に、図12に破線で示すように、不動体前側板14の軸受部14aの部分の板厚が大きい値t14に設定されると、不動体前側板14の軸受部14aと筒状部材6の外周面6b’との間で(図12中の位置Pで)こじりが生じてしまい、筒状部材6を概略光源1(図3参照)の光軸1’(図3参照)方向(図12の上下方向)に円滑にガイドできなくなってしまうおそれがある。   As in the lighting device 30 of the first embodiment, the bearing member 7 (see FIG. 1) and the non-moving object front side plate 14 (see FIG. 1) are connected via a plurality of components, and the bearing of the bearing member 7 If it is difficult to sufficiently increase the degree of coaxiality between the portion 7b (see FIG. 3) and the bearing portion 14a (see FIG. 3) of the unmoving member front side plate 14, as shown by the broken line in FIG. When the plate thickness of the bearing portion 14a portion of the front side plate 14 is set to a large value t14, between the bearing portion 14a of the non-moving object front side plate 14 and the outer peripheral surface 6b ′ of the cylindrical member 6 (in FIG. 12). There is a risk that the twisting occurs at the position P and the cylindrical member 6 cannot be guided smoothly in the direction of the optical axis 1 ′ (see FIG. 3) of the general light source 1 (see FIG. 3) (vertical direction in FIG. 12). There is.

この点に鑑み、第1の実施形態の照明装置30では、図12に実線で示すように、不動体前側板14のうち、軸受部14a以外の部分の板厚t14よりも、軸受部14aの部分の板厚t14aが小さい値に設定されている。そのため、第1の実施形態の照明装置30によれば、不動体前側板14の軸受部14aと筒状部材6の外周面6bとの間でこじりが生じてしまうおそれを低減することができる。   In view of this point, in the illuminating device 30 of the first embodiment, as shown by a solid line in FIG. 12, the thickness of the bearing portion 14a is larger than the plate thickness t14 of the portion other than the bearing portion 14a in the unmoving object front side plate 14. The plate thickness t14a of the portion is set to a small value. Therefore, according to the illuminating device 30 of 1st Embodiment, a possibility that a twist may arise between the bearing part 14a of the non-moving body front side plate 14 and the outer peripheral surface 6b of the cylindrical member 6 can be reduced.

更に、第1の実施形態の照明装置30では、導光レンズ2(図11(A)参照)の出射面2c1,2c2(図11(A)参照)からの光を反射して照明装置30の照射方向(図11(A)の下側)に照射するために導光レンズ2の周囲に配列された複数の反射面21a1,21a2,21a3,21a4,21a5,21a6,21a7,21a8,21a9,21a10,21a11,21a12,21a13,21a14,21a15,21a16,21a17,21a18,21a19,21a20,21a21,21a22,21a23,21a24,21a25,21a26,21a27,21a28,21a29,21a30,21a31,21a32,21a33,21a34,21a35,21a36(図2参照)を有するリフレクタ21(図2および図11(A)参照)が設けられている。更に、相互に隣接する2つの反射面21a1,21a2,21a3,21a4,21a5,21a6,21a7,21a8,21a9,21a10,21a11,21a12,21a13,21a14,21a15,21a16,21a17,21a18,21a19,21a20,21a21,21a22,21a23,21a24,21a25,21a26,21a27,21a28,21a29,21a30,21a31,21a32,21a33,21a34,21a35,21a36が不連続な面によって形成されている。   Furthermore, in the illuminating device 30 of 1st Embodiment, the light from the output surfaces 2c1 and 2c2 (refer FIG. 11 (A)) of the light guide lens 2 (refer FIG. 11 (A)) is reflected, and the illuminating device 30 of FIG.

Furthermore, two mutually adjacent reflecting surfaces 21a1, 21a2, 21a3, 21a4, 21a5, 21a6, 21a7, 21a8, 21a9, 21a10, 21a11, 21a12, 21a13, 21a14, 21a15, 21a16, 21a17, 21a18, 21a19, 21a20, 21a21, 21a22, 21a23, 21a24, 21a25, 21a26, 21a27, 21a28, 21a29, 21a30, 21a31, 21a32, 21a33, 21a34, 21a35, 21a36 are formed by discontinuous surfaces.

そのため、第1の実施形態の照明装置30によれば、導光レンズ2(図8および図11(A)参照)を回転させることにより、照明装置30の照射方向(図11(A)の下側)から照明装置30を見た時に光って見える反射面21a1,21a2,21a3,21a4,21a5,21a6,21a7,21a8,21a9,21a10,21a11,21a12,21a13,21a14,21a15,21a16,21a17,21a18,21a19,21a20,21a21,21a22,21a23,21a24,21a25,21a26,21a27,21a28,21a29,21a30,21a31,21a32,21a33,21a34,21a35,21a36(図2参照)を変化させることができる。   Therefore, according to the illuminating device 30 of 1st Embodiment, by rotating the light guide lens 2 (refer FIG. 8 and FIG. 11 (A)), the irradiation direction (FIG. 11 (A) below) of the illuminating device 30 is rotated.
