The area of the member (details will be described later) can be increased.

(Support member)
The support member 24 supports the substrate group 23 on which the light emitting element 21 is mounted. The support member 24 also has a function of a heat sink that dissipates heat from the light emitting element 21.
As shown in FIGS. 9 and 15, the support member 24 supports the substrate group 24 facing the substrate group 23 and supporting the substrate group 23, and the power supply unit 28 provided on the back side of the substrate support surface 24 a. Power supply unit support surface 24b, and convex portions 24c that are formed at both ends of the substrate support surface 24a and project in the light irradiation direction. The substrate support surface 24 a is formed wider than the width of the substrate group 23. The support member 24 is formed such that a substrate support surface 24a that supports the substrate group 23 is recessed in the direction of the instrument body 10 with respect to the convex portion 24c.

  The support member 24 fixes the substrate group 23 on the substrate support surface 24a by a plurality of substrate fixing members 25 (details will be described later) provided at both ends of the substrate group 23 in the width direction. A plurality of protrusions are formed on the back surface (power supply unit support surface 24 b) of the substrate support surface 24 a of the support member 24 by screws 26 or the like for fixing the substrate fixing member 25 to the support member 24.

Here, as shown in FIG. 7, the support member 24 includes a first substrate fixing portion and a second substrate fixing portion for fixing the substrate group 23 to both ends of the support member 24 in the longitudinal direction. Yes. The first substrate fixing portion and the second substrate fixing portion are, for example, screw holes for attaching screws 26 and the like for fixing the substrate fixing member 25 protruding from the power supply unit support surface 24b at both ends in the longitudinal direction of the support member 24. And so on.
The through portion 24d is preferably provided between the first substrate fixing portion and the second substrate fixing portion. Thereby, it is possible to prevent the wiring 28d routed from the power supply unit support surface 24b to the substrate support surface 24a through the through portion 24d from being caught by the tip of the screw 26 exposed on the power supply unit support surface 24b.

Further, as shown in FIG. 7, the support member 24 has a first attachment portion (a first attachment portion for attaching the light emitting unit 20 to the instrument main body 10 on the back surface side (power supply portion support surface 24 b) of the substrate support surface of the support member 24. A first spring receiving portion 27a) and a second attachment portion (second spring receiving portion 27b) are provided.
More preferably, the through portion 24d is provided between the first spring receiving portion 27a and the second spring receiving portion 27b. As a result, the wiring 28d routed from the power supply support surface 24b to the substrate support surface 24a through the through portion 24d is attached to the tip of the screw 26 exposed on the power supply support surface 24b or the power supply support surface 24b. It is possible to prevent the first spring receiving portion 27a and the second spring receiving portion 27b from being caught.

  Further, as shown in FIG. 14, the penetrating portion 24 d is more preferably provided at a position facing the power source portion 28 of the support member 24. By providing the through portion 24d at a position facing the power supply portion 28, the wiring 28d led out from the power supply portion 28 is not exposed to the power supply portion support surface 24b of the support member 24, and is exposed on the substrate support surface 24a through the through portion 24d. Can be connected to the substrate group 23. For this reason, it is not necessary to route the wiring 28d in a wide area on the support member 24, the wiring 28d can be shortened, and the assembly of the light emitting unit 20 is improved. Further, since the wiring is not exposed to the outside of the 28d, the safety is improved and the double coating of the wiring becomes unnecessary.

As shown in FIG. 15, the support member 24 has fixing holes 24 e and 24 f which are second fixing holes formed on the end side of the support member 24. The fixing holes 24e and 24f are provided at positions facing the fixing holes 221a and 221b of the main cover part 221, respectively.
The support member 24 and the main cover portion 221 (see FIG. 10) are fixed by a main cover portion fixing component such as a rivet. The fixing hole portion 24e of the support member 24 and the fixing hole portion 221a of the main cover portion 221, and the fixing hole portion 24f of the support member 24 and the fixing hole portion 221b of the main cover portion 221 are respectively formed by rivets (not shown).

In this case, for example, rivets are passed from the main cover portion 221 side to the fixing hole portion 24e and the fixing hole portion 221a, and the fixing hole portion 24f and the fixing hole portion 221b, which are positioned to overlap each other, and the support member 24 side Crush the rivets with. Thereby, the main cover part 221 and the support member 24 are fixed.
The fixing holes 24e and 24f are formed in a circular shape, for example. By forming the fixing holes 24e and 24f of the support member 24 in a circular shape and the fixing holes 221a and 221b of the main cover portion 221 in an oval shape, the main cover portion 221 is formed in a high temperature environment or the like. Even in the case of deformation, it is possible to absorb the displacement of the fixing holes 24e and 24f due to the deformation.

The support member 24 has a first engaged portion formed on the end side of the support member 24.
As illustrated in FIG. 15, the support member 24 includes, as the first engaged portion, for example, protrusions 24 g and 24 h from which a part of the support member 24 protrudes. The protrusions 24g and 24h shown in FIG. 15 are formed so as to cut and raise part of the substrate support surface 24a of the support member 24 and rise in the holes 222a and 222b of the first end cover 222. 222b (see FIG. 11).
The support member 24 may have a hole (not shown) instead of the protrusions 24g and 24h as the first engaged portion. In this case, the first end cover 222 is provided with a protruding portion as a first engaging portion, and the protruding portion is locked in the hole portion of the support member 24.

The support member 24 has a second engaged portion formed on the end side of the support member 24.
As shown in FIG. 15, the support member 24 includes, for example, engaging holes 24 i and 24 j (the engaging holes 24 j are not shown) as the second engaged portion. When the first end cover 222 is attached to the engagement holes 24i and 24j of the support member 24, the protrusions 222c and 222d (see FIG. 11) of the first end cover 222 are locked.
The engagement holes 24i and 24j are formed in a rectangular shape, for example. By forming the engagement holes 24i and 24j of the support member 24 in a rectangular shape, even when the first end cover 222 is deformed in a high temperature environment or the like, the deformation of the first end cover 222 is absorbed. Can do.

  The support member 24 has the same configuration as the fixing holes 24e and 24f, the protrusions 24g and 24h, and the engagement holes 24i and 24j at the other end of the support member 24 to which the second end cover 223 is attached. A fixing hole, a protrusion, and a hole are provided.

Hereinafter, the substrate fixing member 25 a to the substrate fixing member 25 n are referred to as the substrate fixing member 25.

As shown in FIG. 16, the substrate fixing member 25 has a shape that supports the side portion of the substrate group 23 and projects on the light emitting element mounting surface of the substrate group 23. The substrate fixing member 25 is fixed to the support member 24 with screws 26.
For this reason, the substrate group 23 is fixed so as not to float with respect to the support member 24.

FIG. 17 is an orthographic projection showing the shapes of the board fixing members 25a to 25c, 25e to 25g, 25h to 25j, and 25l to 25n in FIG. 17A is a front view of the substrate fixing member, FIG. 17B is a left side view of the substrate fixing member, and FIG. 17C is a right side view of the substrate fixing member. FIG. 17D is a top view of the substrate fixing member, FIG. 17E is a bottom view of the substrate fixing member, and FIG. 17F is a rear view of the substrate fixing member.
A substrate fixing member (hereinafter referred to as a substrate fixing member 251) shown in FIG. 17 is formed between the substrate group 23 and the convex portions 24c formed in both ends of the substrate supporting surface 24a of the supporting member 24 and projecting in the light irradiation direction. A main part 251a disposed on the board, a board pressing part 251b that covers a part of the mounting surface of the board group 23 and holds the board group 23 in the direction of the support member 24, and a reflective component that holds the reflecting member on the surface of the main part 251a Holding part 251c. The substrate fixing member 251 has a screwing portion 251 d that is screwed when the substrate fixing member 251 is fixed with the screw 26.

As shown in FIGS. 16 and 17, the substrate fixing member 251 fixes the reflecting member that reflects the light emitted from the light emitting element 21. Specifically, the substrate pressing portion 251b of the substrate fixing member 251 moves the first reflective component 29a (see FIG. 9) that exposes the light emitting element 21 and covers the substrate group 23 in the direction of the support member 24 together with the substrate group 23. Hold down.
In addition, the reflection component holding portion 251c of the board fixing member 251 includes a second reflection component 29b arranged to be inclined from both ends in the width direction of the first reflection component 29a toward the light irradiation direction from the light emitting element 21; The third reflective component 29c (see FIG. 9) is held on the surface of the main portion 251a. At this time, the reflective component holding part 251c is configured such that a part of the top portion is provided in a state where a gap capable of holding the second reflective component 29b or the third reflective component 29c is provided between the reflective component holding portion 251c and the top of the convex portion 24c of the support member 24. It is formed to cover. That is, the reflective component holding portion 251 c is formed in a shape that does not adhere to the top of the convex portion 24 c of the support member 24 when the substrate fixing member 251 is attached to the support member 24. The second reflective component 29b or the third reflective component 29c can be held in a gap formed between the reflective component holding portion 251c and the top of the convex portion 24c of the support member 24.

FIG. 18 is an orthographic projection showing the shapes of the substrate fixing members 25d and 25k in FIG. 18A is a front view of the substrate fixing member, FIG. 18B is a left side view of the substrate fixing member, and FIG. 18C is a right side view of the substrate fixing member. FIG. 18D is a top view of the substrate fixing member, FIG. 18E is a bottom view of the substrate fixing member, and FIG. 18F is a rear view of the substrate fixing member.
A substrate fixing member (hereinafter referred to as a substrate fixing member 252) shown in FIG. 18 includes a main portion 252a corresponding to the main portion 251a of the substrate fixing member 251, a substrate pressing portion 252b corresponding to the substrate pressing portion 251b, and a reflection. A reflection component holding portion 252c corresponding to the component holding portion 251c and a screwing portion 252d corresponding to the screwing portion 251d are provided. The board fixing member 252 further includes a wiring fixing mechanism 252e that fixes the wirings 23c and 28d connected to the board group 23.
The substrate fixing member 252 is disposed at a position covering the wiring 23c or 28d (see FIG. 12) connected to the light emitting element substrates 231 and 232. In the light emitting unit 20 of the present embodiment, the substrate fixing member 252 is disposed at a joint portion of the light emitting element substrates 231 and 232 in the substrate group 23. The wiring fixing mechanism 252e is formed in a shape that can secure a space through which the wiring 23c or 28d can be led out even when the substrate fixing member 252 is fixed to the support member 24. The wiring 23c or 28d is connected to the light emitting element substrates 231 and 232 through the wiring fixing mechanism 252e. For this reason, by using the substrate fixing member 252, it is possible to prevent the substrate fixing member 25 from pressing the wirings 23c and 28d.

  The main part 252a, the board pressing part 252b, the reflection component holding part 252c, and the screwing part 252d of the board fixing member 252 are the main part 251a, the board pressing part 251b, the reflection part holding part 251c, and the screw fixing part 252d. It has the same function as the screwing portion 251d.

Such a substrate fixing member 25 (substrate fixing members 251 and 252) is formed, for example, by injection molding a resin material.
The substrate fixing member 25 is preferably formed of a highly reflective material. Even if a part of the substrate fixing member 25 is exposed from the first reflecting component 29a, the second reflecting component 29b, or the third reflecting component 29c, the light of the light emitting element 21 can be efficiently reflected. It is.
Further, the substrate fixing member 25 (substrate fixing members 25d and 25k shown in FIGS. 9 and 16) disposed so as to cover the wirings 23c and 28d connected to the light emitting element substrates 231 and 232 is formed of a transparent material. It is preferable. Since the wiring state of the wiring 23c can be confirmed through the substrate fixing member 25, it is possible to more easily prevent the wirings 23c and 28d from being pressed by the substrate fixing member 25.

(Reflective member)
The reflection member 29 has a function of reflecting the light emitted from the light emitting element 21. The light emitted from the light emitting element 21 is reflected by the reflecting member 29 in a preset direction (for example, a direction toward the floor surface). The reflection member 29 is fixed by an adhesive, a pin, a screw or the like at an arbitrary position such as the substrate group 23, the support member 24, or the substrate fixing member 25.

  As shown in FIGS. 8 and 9, the light emitting unit 20 according to the present embodiment includes a first reflection component 29 a, a second reflection component 29 b, and a third reflection component 29 c as the reflection member 29. . The first reflective component 29a exposes the light emitting element 21 and covers the substrate group 23 (with the light emitting element substrates 231 and 232). The second reflective component 29b is disposed so as to be inclined from one end portion in the width direction of the first reflective component 29a toward the irradiation direction of the light from the light emitting element 21. The third reflective component 29c is disposed so as to be inclined from the other end portion in the width direction of the first reflective component 29a toward the direction of irradiation of light from the light emitting element 21. The first reflective component 29a, the second reflective component 29b, and the third reflective component 29c are different components. Thereby, each attachment of the 1st reflective component 29a, the 2nd reflective component 29b, and the 3rd reflective component 29c becomes easy.

Further, a resistor element (not shown) may be provided on the mounting surface side of the light emitting element 21 of the substrate group 23. In this case, the first reflecting component 29a is provided with an opening for exposing the light emitting element 21 and an opening for exposing the resistance element.
By providing the above-described opening in the first reflective component 29a, the light emitted from the light emitting element 21 is reflected on the entire surface of the first reflective component 29a, the second reflective component 29b, and the third reflective component 29c, thereby efficiently illuminating. Used for light emission of the device 1.

FIG. 19 is a perspective view showing a state in which the first reflective component 29a, the second reflective component 29b, and the third reflective component 29c are attached to the board fixing member 25 (25a to 25n). 20 is a cross-sectional view showing a CC ′ cross-section shown in FIG.
As shown in FIGS. 19 and 20, the second reflective component 29 b has one end on the side adjacent to the substrate group 23 in the width direction of the second reflective component 29 b positioned outside one end in the width direction of the substrate group 23. Are arranged as follows. The third reflective component 29c is arranged so that one end of the third reflective component 29c adjacent to the substrate group 23 in the width direction is located outside the other end of the substrate group 23 in the width direction. That is, the second reflective component 29 b and the third reflective component 29 c are arranged so as not to fog over the first reflective component 29 a provided on the substrate group 23.

The second reflective component 29b is preferably arranged so that one end of the second reflective component 29b adjacent to the substrate group 23 in the width direction faces the one end in the width direction of the substrate group 23 without a gap. The third reflective component 29c is preferably arranged so that one end of the third reflective component 29c adjacent to the substrate group 23 in the width direction faces the other end in the width direction of the substrate group 23 without a gap. .
Here, in this embodiment, “opposing without a gap” is limited to the case where the first reflective component 29a and the second reflective component 29b, and the first reflective component 29a and the third reflective component 29c are completely arranged without a gap. I can't. The term “opposing without a gap” means the position of one end on the side adjacent to the substrate group 23 in the width direction of the second reflective component 29b when viewed from the mounting surface side of the substrate group 23 (light emitting element substrates 231 and 232). This means that the position of one end in the width direction of the substrate group 23 coincides.

  The first reflective component 29 a is fixed on the substrate support surface 24 a of the support member 24 by the substrate fixing member 25. Further, the second reflective component 29 b and the third reflective component 29 c are fitted and fixed in a gap formed between the top of the convex portion 24 c of the support member 24 and a part of the substrate fixing member 25. Specifically, the second reflective component 29b and the third reflective component 29c are fitted into a gap formed between the top of the convex portion 24c of the support member 24 and the reflective component holding portion 251c of the substrate fixing member 251. Yes. Accordingly, the second reflective component 29b and the third reflective component 29c are inclined along the shape of the top of the convex portion 24c of the support member 24. The second reflective component 29b and the third reflective component 29c are fixed by different board fixing members 25.

  Thereby, in the assembled light emitting unit 20, the second reflective component 29b and the third reflective component 29c are arranged to be inclined toward the projecting portions 221c and 221d formed on the inner wall surface of the translucent cover, respectively. . That is, the second reflective component 29b has one end on the side not adjacent to the substrate group 23 in the width direction of the second reflective component 29b (that is, the other end opposite to one end adjacent to the substrate group 23). The cover 22 is disposed to be inclined toward the protrusion 221 c formed on the inner wall surface. In addition, the third reflective component 29c has one end on the side not adjacent to the substrate group 23 in the width direction of the third reflective component 29c (that is, the other end facing the one end adjacent to the substrate group 23). The cover 22 is disposed so as to be inclined toward the protruding portion 221d formed on the inner wall surface. Thus, even when the second reflective component 29b or the third reflective component 29c is displaced in the floor direction due to weight or the like, the protruding portion 221c or 221d of the translucent cover 22 serves as a stopper, and the second reflective component 29b or The third reflective component 29c can be prevented from falling.

21A, the first reflective component 29a disposed on the substrate group 23 is disposed on the light-emitting element substrate 232 and the first reflective component 291a disposed on the light-emitting element substrate 231. And the first reflecting component 292a. In FIG. 21A, the first reflective component 291a and the first reflective component 292a are indicated by diagonal lines.
At this time, the first reflective components 291a and 292a cover a region excluding the region surrounded by the power supply connection terminal group (connectors 231a and 232a) and the board connection terminal group (connectors 231b and 232b). That is, the first reflective component 291a covers the board group 23 from one end of the board group 23 to the installation positions of the connectors 231a and 231b. The first reflective component 292a covers the board group 23 from the other end of the board group 23 to the installation positions of the connectors 232a and 232b. Note that the wiring 23c and the wiring 28d are not illustrated in FIG.

  In the “region surrounded by the power supply connection terminal group (connectors 231a and 232a) and the board connection terminal group (connectors 231a and 232a)”, the opposite short-side ends on the light emitting element substrates 231 and 232 are arranged. Two or more light emitting elements 21 arranged in the part are included. In FIG. 21, four light emitting elements 21 are included in a region that is not covered with the first reflective components 291 a and 292 a.

Furthermore, as shown in FIG. 21B, the light emitting unit 20 includes a substrate facing portion reflection component 293a disposed so as to cover the short sides of the two light emitting element substrates 231 and 232. Also good. In FIG. 21B, the first reflection component 291a, the first reflection component 292a, and the substrate facing portion reflection component 293a are indicated by hatching.
As a result, the light emitted from the light emitting element 21 can be sufficiently reflected even at the joint portion between the two light emitting element substrates 231 and 232, so that the brightness can be made uniform over the entire surface of the substrate group 23. .

(Spring holder)
As shown in FIG. 22, the spring receiving portion 27 maintains the state where the light emitting unit 20 is attached to the instrument main body 10 by engaging with the spring part 13 (see FIG. 5B) of the instrument main body 10. Used for Specifically, the first spring receiving portion 27 a engages with the first spring portion 13 a of the instrument body 10, and the second spring receiving portion 27 b engages with the second spring portion 13 b of the instrument body 10. That is, the spring part 13 (the first spring part 13a and the second spring part 13b) and the spring receiving part 27 (the first spring receiving part 27a and the second spring receiving part 27b) place the light emitting unit 20 in the light emitting unit mounting recess 111. It functions as an attachment state maintaining unit that maintains the attached state. Note that the attachment state maintaining unit may have a shape different from the spring part 13 and the spring receiving part 27 described in the present embodiment as long as the state where the light emitting unit 20 is attached to the instrument body 10 is maintained.

(Power supply part)
The power supply unit 28 houses a lighting circuit (that is, a power supply circuit) for the light emitting element 21 such as an LED. The power supply unit 28 is connected to a power supply cable led into the light emitting unit mounting recess 111 from a mounted surface such as a ceiling to which the instrument main body 10 shown in FIG. 5 is mounted.
As shown in FIG. 22, the power supply unit 28 includes a power supply board 28 a including a power supply circuit, an insulating member 28 b, a power supply box 28 c that accommodates the power supply board 28 a and the insulating member 28 b therein, and power for the light emitting element 21. Wiring 28d (wiring 28d is not shown in FIG. 22).
The power supply unit 28 is disposed close to the support member 24.

The power supply circuit provided on the power supply board 28 a converts, for example, alternating current power supplied from a power supply cable into direct current, and supplies the output (that is, direct current power) to the light emitting element 21. The power supply substrate 28a is fixed to the surface of the insulating member 28b on the support member 24 side.
Further, as shown in FIG. 14, the power supply board 28a is disposed closer to the support member 24 in the internal space of the power supply box 28c.

The insulating member 28b is made of a resin material having a high melting point and insulating properties such as polypropylene and polyethylene. The insulating member 28 b is disposed on the power supply unit support surface 24 b of the support member 24. As a result, the power supply substrate 28 a is disposed on the insulating member 28 b and insulated from the support member 24.
The insulating member 28b has, for example, a box shape formed by bending a plurality of sheet-like members, and is disposed so as to surround the power supply substrate 28a.

The power supply box 28c is made of a material such as plastic, aluminum, or stainless steel. The power supply box 28c is a housing that covers the power supply board 28a.
The wiring 28 d is connected to the substrate group 23 through the through portion 24 d provided on the substrate support surface 24 a of the support member 24.

The power supply unit 28 is fixed to the power supply unit support surface 24b of the support member 24 by, for example, a claw unit (not shown) provided in the power supply box 28c. The power supply unit 28 may be fixed to the power supply unit support surface 24b of the support member 24 by a fastening member such as a screw.
The power supply unit 28 overlaps with a power supply cable (not shown) when viewed in the normal direction of the mounted surface. That is, the power supply cable is wired in a power supply cable housing space secured between the upper surface of the power supply unit 28 and the instrument body 10. For this reason, the attachment of the light emitting unit 20 is not hindered by the power supply cable.

The light emitting unit 20 may include a wiring protection insulating member that is positioned inside the through portion 24d of the support member 24 and protects the wiring 28d. Here, the “inside” of the penetrating portion 24d indicates a direction toward the central axis of the penetrating portion 24d.
In the light emitting unit 20, the wiring 28 d is led out from the power supply unit 28 to the substrate support surface 24 a side through the through part 24 d of the support member 24. At this time, the wiring 28d may hit and damage the inner wall of the through portion 24d of the support member 24. For example, when the wiring 28d is covered with a covering material, the covering material may be peeled off. For this reason, it is preferable to provide a wiring protection insulating member that makes it difficult for the inner wall of the through portion 24d and the wiring 28d to come into contact with each other.

Examples of the wiring protection insulating member include the following.
(1) First Example FIG. 23A is a perspective sectional view showing a BB ′ section of FIG.
When the penetrating portion 24d is provided at a position facing the power supply portion 28 of the support member 24, the insulating member 28b can also serve as an insulating member for wiring protection as shown in FIG. That is, the wiring 28d connected to the power supply substrate 28a is connected to the substrate group 23 provided on the substrate support surface 24a through the through portion 24d of the support member 24. At this time, since the insulating member 28 b is provided between the power supply substrate 28 a and the support member 24, a through portion 281 b smaller than the through portion 24 d is provided in the insulating member 28 b, and the through portion 24 d of the support member 24 is provided. The insulating member 28b is disposed so that the through portion 281b of the insulating member 28b overlaps. For this reason, it is possible to make it difficult for the insulating member 28b to contact the penetrating portion 24d of the support member 24 and the wiring 28d.

(2) Second Example FIG. 23B shows the configuration of the wiring 28d led out to the substrate support surface 24a side through the power supply substrate 28a, the insulating member 28b, and the through portion 24d provided in the support member 24. It is sectional drawing shown.
As shown in FIG. 23B, the wiring protection insulating member 28e, which is a component different from the insulating member 28b, is provided on at least one of the substrate support surface 24a and the power supply unit support surface 24b of the support member 24 (FIG. In B), it may be provided in close contact with the power source support surface 24b). The wiring protection insulating member 28e is formed of, for example, an insulating resin material.
As shown in FIG. 23B, the wiring protection insulating member 28e includes a through part 281e smaller than the through part 24d, and the through part 24d of the support member 24 and the through part of the wiring protection insulating member 28e. The wiring protection insulating member 28e is arranged so as to overlap with 281e. For this reason, the wiring protection insulating member 28e makes it difficult for the penetrating portion 24d of the support member 24 and the wiring 28d to come into contact with each other, and damage to the wiring 28d can be suppressed.
In the case of the second example, it is not necessary that the penetrating portion 24d is provided at a position facing the power supply portion 28 of the support member 24 as in the first example. Whatever the position of the penetrating part 24d is provided on the support member 24, the wiring protection insulating member 28e may be provided in close contact with the penetrating part 24d.

(3) Third Example FIG. 23C shows a configuration of the power supply substrate 28a, the insulating member 28b, and the wiring 28d led out to the substrate support surface 24a side through the through portion 24d provided in the support member 24. It is sectional drawing shown.
As shown in FIG. 23C, a wiring protection insulating member 28e, which is a component different from the insulating member 28b, may be provided so as to cover at least the inner wall of the through portion 24d. The wiring protection insulating member 28e is formed of, for example, an insulating resin material.
As shown in FIG. 23C, the wiring protection insulating member 28e is provided so as to cover at least the inner wall of the through portion 24d. For this reason, it becomes difficult for the corner | angular part of the penetration part 24d of the supporting member 24, and the wiring 28d to contact, and damage to the wiring 28d can be suppressed.
Further, the wiring protection insulating member 28e may cover the substrate support surface 24a and the power supply unit support surface 24b of the support member 24. In this case, the insulating member 28e for wiring protection covers the corners formed by the substrate supporting surface 24a and the power source supporting surface 24b of the supporting member 24 and the inner wall of the penetrating portion 24d, thereby further suppressing damage to the wiring 28d. can do.
Also in the case of the third example, it is not necessary that the penetrating part 24d is provided at a position facing the power supply part 28 of the support member 24, and no matter what position of the supporting member 24 the penetrating part 24d is provided, the wiring The protective insulating member 28e may be provided so as to cover the inner wall of the penetrating portion 24d.
