*** Description of assembly operation ***
Next, assembly of the light emitting element substrate 210, the holding portion 220, the substrate fixing member 400, and the cover portion 230 will be described.
(1) FIG. 11 is a view in the direction of arrow X in FIG. 5. As shown in FIG. 11, first, the light emitting element substrate 210 is inserted into the first through hole 224-1 and the second through hole 224 of the holder 220. The light emitting element substrate 210 is disposed in the holding portion 220 such that the second light emitting element −2 is located in the recess 214 of the substrate 212. FIG. 11 shows a first through hole 224-1, a second through hole 224-2, and a recess 214. Further, the first pressing portion 411 and the second pressing portion 422 are shown by a two-dot chain line. A width W1 (IN) indicating the inner dimension of the through holes, a width W1 (OUT) indicating the inner dimension, and a width W2 indicating the dimensions of the recesses 214 are shown. Moreover, the dimension L1 of the longitudinal direction of 2nd through-hole 224-2 was shown. The first through hole 224-1 is also similar to the second through hole 224-2. In FIG. 11, the width W1 (IN) is the same as or slightly longer than the width W2, and the dimension L1 is slightly shorter than the longitudinal length of the second through hole 224-2. The width W1 (IN), the width W1 (OUT), and the dimension L1 indicate the dimensions W11 and W22 (FIG. 6) and the dimension W33 (FIG. 8) of the substrate fixing member 400. The dimensions of the through holes are determined in relation to the dimensions W11, W22 (FIG. 6) and the dimension W33 of the substrate fixing member 400.
(2) Next, after the light emitting element substrate 210 is disposed with respect to the holding portion 220, the first protrusion 410 and the second protrusion 420 of the substrate fixing member 400 are formed in the through hole from the other surface 221b. The first holding portion 411 and the second holding portion 422, which are tip portions, are pushed in and fitted in (FIGS. 5 and 7). When the first protrusion 410 and the second protrusion 420 are fitted into the through hole, the first pressing portion 411 and the second pressing portion 422 press the substrate 212 against one surface 221 a of the holding portion 220. Insert in In addition, since the first protrusion 410 and the second protrusion 420 are positioned in the recess 214, it is possible to prevent the substrate 212 from shifting in the longitudinal direction or the lateral direction.
(3) Next, as shown in FIG. 7, the cover 230 is engaged with the holder 220 so that the diffusion part 234 covers the light emitting element substrate 210, and the cover 230 is fixed to the holder 220. At this time, as shown in FIG. 7, the reflective portion 232 covers the convex portion 213 and the concave portion 214 of the substrate 212, and the first contact portion 232-1 and the second contact portion 232-2 of the reflective portion 232. Prevents the substrate fixing member 400 from coming off the holding portion 220 by suppressing the movement of the first protrusion 410 and the second protrusion 420 by contacting the first protrusion 410 and the second protrusion 420. It can prevent.

As shown in FIG. 12, in the light source unit 200, the rising direction 222 d in which the first side surface portion 222-1 and the second side surface portion 222-2 stand up is the first side wall portion 113-1 and the second side wall It is attached to the instrument main body 1000 along the rising direction 113 d of the portion 113-2. The substrate fixing member 400 is positioned in the erecting direction 222d and protrudes from the top portions 222-T1 and 222-T2 or more of the first side surface portion 222-1 and the second side surface portion 222-2 in the erecting direction 222d. And a distal end facing portion 444 facing the distal end portion 610.
The dimension T1 shown in FIG. 12 is the length from the other surface 221b of the first side surface portion 222-1 to the top portion 222-T1 of the first side surface portion 222-1. The dimension T2 is a length from the other surface 221b of the second side surface 222-2 to the top 222-T2 of the second side surface 222-2. The dimension T3 is a length from the other surface 221b of the substrate fixing member 400 to the tip facing portion 444. In this embodiment, the tip end facing portion 444 doubles as a part of the upper surface 449. In FIG. 12, the dimension T1 and the dimension T2 have substantially the same length. Dimension T3 is longer than dimension T1 and dimension T2. Therefore, since the tip end portion 610 of the projecting attachment portion 600 is restricted from projecting in the direction of the other surface 221b by the upper surface 449 which is the tip facing portion 444, the dimension of the tip portion 610 from the other surface 221b is the dimension T1. Alternatively, it does not enter the area of dimension T2.

*** Description of the effect ***
According to the present embodiment,
First, the light emitting element substrate 210 is fixed to the holding portion 220 by the substrate fixing member 400 having the first protrusion 410, the second protrusion 420, and the fitting portion 441, so that the substrate 212 is not damaged. It can be easily fixed to the holder 220.
Second, since the first abutment portion 232-1 and the second abutment portion 232-2 of the reflection portion 232 of the cover portion 230 abut on the first projection portion 410 and the second projection portion 420, It is possible to prevent the first protrusion 410 and the second protrusion 420 from coming off the through hole.
Third, since the substrate 212 is provided with the convex portion 213 and the concave portion 214, and the first protrusion 410 and the second protrusion 420 are fitted in the concave portion 214, the reflection portion 232 of the cover portion 230 is In order to cover the convex portion 213 of the substrate 212, it can be formed large and wide.
Fourth, since the substrate fixing member 400 has the fitting portion 441, a plurality of electric wires or the like for supplying power to the light emitting element substrate 210 from the lighting device 270 disposed in the holding portion 220 is accommodated in the fitting portion 441. Wires can be bundled. Therefore, the space in the recess shape of the recess shape formed by the attachment portion 221, the first side surface portion 222-1, and the second side surface portion 222-2 in the holding portion 220 can be effectively used.
Fifth, by installing the substrate fixing member 400 at a position facing the fixing hole 112 d of the tool main body 100 of the holding portion 220, a projecting mounting portion such as a bolt for mounting the tool main body 100 to the mounting portion (building member) It is possible to prevent 600 from being inserted into the recess shape of the holding portion 220.

As a modification of the present embodiment, in the substrate fixing member 400, as shown in FIG. 10, the first protrusion 410 and the second protrusion 420 may not have a symmetrical shape. Moreover, the fitting part 441 may be formed in the side surface.
FIG. 10A shows a shape in which the first protrusion 410 and the second protrusion 420 protrude from the inside of the area of the bottom surface 448. In FIG. 10 (b), the second projection 420 is divided into two, and the first projection 410 is shaped so as to be a part of the side surface, not all. FIG. 10C shows a shape in which the fitting portion 441 is formed in a slit shape substantially parallel to the bottom surface 448.

  In the present embodiment, the substrate 212 is described as having a shape having a convex portion 213 and a concave portion 214. However, the recess may communicate with the through hole so that the first protrusion 410 and the second protrusion 420 are fitted into the opening. Moreover, the convex part should just be formed outside the concave part.

  Although the present embodiment has been described with regard to the through hole having a long hole shape, any shape may be adopted as long as the first protrusion 410 and the second protrusion 420 are fitted.

  As a modification of the present embodiment, the light source cover 240 may be configured to prevent the substrate 212 from shifting in the longitudinal direction without providing the convex portion 213 of the substrate 212. Further, a convex portion or a concave portion may be provided in the reflection portion of the cover portion 230.

  As a modification of the present embodiment, the light source cover 240 may be configured to prevent the substrate 212 from shifting in the longitudinal direction without providing the convex portion 213 of the substrate 212. In this case, as shown in FIG. 14, the substrate 212 may have a rectangular shape with the width of the recess 214, and the width in the short direction is substantially the same as the width W2 between the recesses 214 in FIG.
