Description

この発明は、光源装置等の内部で端面を外側に向けて露出させた壁面に装着される反射部材に関する。 The present invention relates to a reflecting member that is mounted on a wall surface that is exposed with an end face facing outward in a light source device or the like.

屋外に設置される表示パネルとして、透光性パネルの背面に光源装置を備えたものがある。このような光源装置では、表示パネルのサイズの変化に対応して照明面積も変更する必要がある。 Some display panels installed outdoors include a light source device on the back of a translucent panel. In such a light source device, it is necessary to change the illumination area in response to a change in the size of the display panel.

そこで、従来の光源装置では、照明面積の変更に対応すべく、それぞれが独立して光源を備えた光源モジュールを複数組み合わせて表示パネルのサイズに応じた照明面積の光源装置を構成するようにしたものがある（例えば、特許文献１参照。）。 Therefore, in the conventional light source device, in order to cope with the change of the illumination area, a light source device having an illumination area corresponding to the size of the display panel is configured by combining a plurality of light source modules each having a light source independently. There are some (for example, refer to Patent Document 1).

このような光源装置では、隣り合う光源モジュールの壁面が互いに接合された状態で内部に存在する。
特開平６−３０１３４７号公報 In such a light source device, the wall surfaces of adjacent light source modules are present inside in a state where they are joined together.
JP-A-6-301347

しかし、複数の光源モジュールを組み合わせて構成された光源装置では、照明面において壁面が対向する部分に光源が存在しないため、壁面のイメージが照明面に暗部として現れ、表示パネルの全面について均一な明度を与えることができない問題がある。 However, in a light source device configured by combining a plurality of light source modules, since the light source does not exist in the portion of the illumination surface facing the wall surface, the image of the wall surface appears as a dark portion on the illumination surface, and the brightness of the entire display panel is uniform. There is a problem that cannot be given.

光源装置内部に存在する壁面のイメージが照明面に現れないようにするため、壁面に反射部材を装着し、各光源モジュールが備える光源から壁面に向かう光を照明面に向けて反射させることが考えられる。 In order to prevent the image of the wall surface existing inside the light source device from appearing on the illumination surface, a reflection member is attached to the wall surface, and the light directed from the light source of each light source module toward the wall surface is reflected toward the illumination surface. It is done.

このような反射部材は、複数の光源モジュールを組み合わせて構成される光源装置だけでなく、内部に端面を外側に向けて露出させた壁面が存在する他の装置においても、美観の向上を目的として用いられる可能性がある。 Such a reflecting member is not only a light source device configured by combining a plurality of light source modules, but also for other devices having a wall surface with the end face exposed to the outside in order to improve aesthetics. May be used.

この発明の目的は、光源装置等の内部の壁面に容易かつ確実に装着することができる反射部材を提供することにある。 An object of the present invention is to provide a reflecting member that can be easily and reliably attached to an inner wall surface of a light source device or the like.

この発明の反射部材は、樹脂平板を折り曲げで形成され、端面が外側に向けて露出した壁面に装着され、第１及び第２の側面、第１及び第２の底面、少なくとも１つの係合対を備えている。第１及び第２の側面は、先端部から基部までの間の少なくとも一部に先端部側から基部側に向かって互いの間隔が徐々に拡大する範囲を含む。第１及び第２の底面は、第１及び第２の側面のそれぞれの基部から第１及び第２の折り曲げ線を挟んで第２及び第１の側面に向かって延出する。係合対は、第１及び第２の底面のそれぞれに形成され、第１の側面と第２の側面とが近接する方向、及び第１及び第２の折り曲げ線に沿う方向に互いに係合する。係合対を係合させた状態で第１の底面と第２の底面との間に壁面が貫通する間隙が形成される。 The reflecting member of the present invention is formed by bending a resin flat plate, and is attached to a wall surface whose end face is exposed outward, and includes at least one engagement pair of first and second side faces, first and second bottom faces. It has. The first and second side surfaces include a range in which the distance between the distal end portion and the base portion gradually increases from the distal end portion side toward the base portion side. The first and second bottom surfaces extend from the respective bases of the first and second side surfaces toward the second and first side surfaces with the first and second fold lines interposed therebetween. The engagement pair is formed on each of the first and second bottom surfaces, and engages with each other in a direction in which the first side surface and the second side surface are close to each other and in a direction along the first and second folding lines. . A gap through which the wall surface penetrates is formed between the first bottom surface and the second bottom surface with the engagement pair engaged.

この構成では、第１及び第２の底面は、第１及び第２の折り曲げ線で第１及び第２の側面のそれぞれの内側に向けて折り曲げて係合対を係合させると、互いに第１の側面と第２の側面とが近接する方向、及び第１及び第２の折り曲げ線に沿う方向への移動を規制される。第１及び第２の側面及び第１及び第２の底面は、閉空間を形成する状態に維持される。 In this configuration, when the first and second bottom surfaces are bent toward the inner sides of the first and second side surfaces at the first and second folding lines, The movement in the direction in which the side surface and the second side surface are close to each other and the direction along the first and second fold lines is restricted. The first and second side surfaces and the first and second bottom surfaces are maintained in a state of forming a closed space.

この構成において、係合対は、第１及び第２の延出部、第１の孔部、第２の孔部、係合片を含むものとすることが好ましい。第１及び第２の延出部は、第１及び第２の底面における第１及び第２の折り曲げ線と反対側の端部から第３及び第４の折り曲げ線を挟んで延出する。第１の孔部は、第１の底面に第３の折り曲げ線から所定距離離れて形成されている。第２の孔部は、第３の折り曲げ線に沿う方向の幅が第１の孔部より狭く、第１の孔部から第１の延出部に連続して形成されている。係合片は、第２の延出部内に形成され第４の折り曲げ線側を挟んで第２の底部から延出し、第１及び第２の孔部に第１の底面の外側から内側に向かって貫通する。 In this configuration, the engagement pair preferably includes first and second extending portions, a first hole portion, a second hole portion, and an engagement piece. The first and second extending portions extend from the ends of the first and second bottom surfaces opposite to the first and second fold lines with the third and fourth fold lines interposed therebetween. The first hole is formed on the first bottom surface at a predetermined distance from the third fold line. The second hole is narrower than the first hole in the direction along the third fold line, and is formed continuously from the first hole to the first extension. The engagement piece is formed in the second extension portion and extends from the second bottom portion with the fourth fold line side in between, and extends from the outside of the first bottom surface to the inside of the first and second holes. Penetrate.

第１の延出部と第２の延出部とを互いに接合させ、係合片を第１及び第２の孔部に第１の底面の外側から内側に向かって貫通させると、第１の孔部における第３の折り曲げ線に平行な側面が係合片と第３の折り曲げ線に直交する方向に当接する。また、第１の延出部に形成された第２の孔部における第３の折り曲げ線に直交する側面が係合片と第３の折り曲げ線に平行な方向に当接する。さらに、第１の延出部に形成された第２の孔部における第３の折り曲げ線に平行な側面が係合片と第１の延出部の面方向に当接する。 When the first extension portion and the second extension portion are joined to each other, and the engagement piece is passed through the first and second holes from the outside to the inside of the first bottom surface, Side surfaces of the hole portion parallel to the third fold line abut on the engagement piece and the direction perpendicular to the third fold line. In addition, the side surface orthogonal to the third fold line in the second hole formed in the first extension part abuts in the direction parallel to the engagement piece and the third fold line. Furthermore, the side surface parallel to the third fold line in the second hole portion formed in the first extension portion abuts in the surface direction of the engagement piece and the first extension portion.

したがって、第３の折り曲げ線に直交する方向、第３の折り曲げ線に平行な方向、第１の延出部の面方向について、第１の底面及び第２の底面の互いに離間する方向への移動が規制され、樹脂平板は第１〜第４の折り曲げ線で折り曲げた状態の形状に確実に維持される。 Accordingly, the first bottom surface and the second bottom surface are moved away from each other in the direction orthogonal to the third fold line, the direction parallel to the third fold line, and the surface direction of the first extension portion. Is regulated, and the resin flat plate is reliably maintained in a shape folded at the first to fourth folding lines.

また、第１及び第２の側面は、先端部から基部までの長さが等しい平面で構成することが好ましい。第１〜第４の折り曲げ線で折り曲げた樹脂平板が三角形の均一な断面形状に維持される。 Moreover, it is preferable to comprise the 1st and 2nd side surface by the plane where the length from a front-end | tip part to a base part is equal. The resin flat plate folded at the first to fourth folding lines is maintained in a uniform triangular cross-sectional shape.

さらに、第１及び第２の底面は、第１及び第２の折り曲げ線と平行な第５及び第６の折り曲げ線であって第１及び第２の折り曲げ線と逆方向に折り曲げられる第５及び第６の折り曲げ線を備えることが好ましい。反射部材を装着すべき壁面が基端側に傾斜面を有する場合に、第１及び第２の底面を壁面の傾斜面に密着させて反射部材を確実に装着することができる。 Further, the first and second bottom surfaces are fifth and sixth fold lines parallel to the first and second fold lines, and are folded in the direction opposite to the first and second fold lines. Preferably, a sixth fold line is provided. When the wall surface on which the reflecting member is to be mounted has an inclined surface on the base end side, the reflecting member can be reliably mounted by bringing the first and second bottom surfaces into close contact with the inclined surface of the wall surface.

この発明によれば、樹脂平板を所定形状に折り曲げた形状を確実に維持することができ、光源装置等の内部の壁面に容易かつ確実に装着することができる。 According to this invention, the shape which bent the resin flat plate to the predetermined shape can be maintained reliably, and it can mount | wear easily and reliably on the inner wall surfaces, such as a light source device.

図１は、この発明の実施形態に係る反射部材が用いられる光源装置を備えた表示パネル装置の斜視図である。図２は、同表示パネル装置の断面図である。 FIG. 1 is a perspective view of a display panel device including a light source device using a reflecting member according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the display panel device.

表示パネル装置１００は、表示パネル１０１と光源装置２００とからなる。表示パネル１０１は、樹脂等の透光性平板からなり、表面に任意の文字、図形、写真等が表記されている。光源装置２００は、内部に例陰極管等の光源２０２を収納し、前面が開放した薄型筐体である。光源装置２００の前面の面積は表示パネル１０１と等しくされており、光源装置２００の前面を被覆するように表示パネル１０１が取り付けられる。 The display panel device 100 includes a display panel 101 and a light source device 200. The display panel 101 is made of a translucent flat plate such as a resin, and arbitrary characters, figures, photographs, etc. are written on the surface. The light source device 200 is a thin casing in which a light source 202 such as a cathode tube is housed and the front surface is open. The area of the front surface of the light source device 200 is equal to that of the display panel 101, and the display panel 101 is attached so as to cover the front surface of the light source device 200.

光源装置２００は、一例として２つの光源モジュール２０１を横方向に連結して構成されている。光源モジュール２０１は、横方向及び縦方向に連結自在に構成されている。表示パネル１０１の面積に応じて光源モジュール２０１の個数及び連結方向を変更することで、表示パネル１０１の面積の変化に対応できる。 As an example, the light source device 200 is configured by connecting two light source modules 201 in the horizontal direction. The light source module 201 is configured to be connectable in the horizontal direction and the vertical direction. By changing the number and connection direction of the light source modules 201 according to the area of the display panel 101, it is possible to cope with a change in the area of the display panel 101.

光源モジュール２０１は、金属平板を素材としてプレス加工等によって前面が開放した薄型筐体に成形されている。光源モジュール２０１の内部には、光源２０２が略全幅にわたって配置されている。光源２０２の両端は、光源モジュール２０１の内側の角部に配置されたカバー２０３で被覆されている。 The light source module 201 is formed into a thin casing whose front surface is opened by pressing or the like using a metal flat plate as a material. Inside the light source module 201, the light source 202 is disposed over substantially the entire width. Both ends of the light source 202 are covered with covers 203 arranged at corners inside the light source module 201.

光源モジュール２０１の一方の壁面２０３は他の壁面よりも低くされている。２つの光源ユニット２０１は、互いの壁面２０３を接合させて連結される。 One wall surface 203 of the light source module 201 is set lower than the other wall surface. The two light source units 201 are connected by joining the wall surfaces 203 to each other.

図３は、同表示パネル装置の要部の拡大断面図である。図３（Ａ）に示すように、連結された２つの光源モジュール２０１のそれぞれで、互いに接合された壁面２０４の近傍には光源２０２が存在しない。このため、表示パネル１０１における壁面２０４に対向する部分には、照明光のイメージとして影部１０２が形成され、表示パネル１０１に表記された文字等の美観が損なわれる。 FIG. 3 is an enlarged cross-sectional view of a main part of the display panel device. As shown in FIG. 3A, the light source 202 does not exist in the vicinity of the wall surface 204 joined to each other in each of the two connected light source modules 201. For this reason, a shadow portion 102 is formed as an image of illumination light on the portion of the display panel 101 facing the wall surface 204, and the aesthetic appearance of characters and the like written on the display panel 101 is impaired.

そこで、図３（Ｂ）に示すように、カバー２０３の上面に載置される反射部材１０を壁面２０４の端部から装着する。光源２０２の光を反射部材１０の側面に反射させ、表示パネル１０１における壁面２０４に対向する部分に配光する。反射部材１０は、図３（Ｂ）の紙面に直交する方向の全長にわたって壁面２０４に装着される。表示パネル１０１に影部１０２が形成されることがなく、表示パネル１０１に表記された文字等の美観を損なうことがない。 Therefore, as shown in FIG. 3B, the reflecting member 10 placed on the upper surface of the cover 203 is attached from the end of the wall surface 204. The light from the light source 202 is reflected on the side surface of the reflecting member 10 and is distributed to the portion of the display panel 101 facing the wall surface 204. The reflecting member 10 is attached to the wall surface 204 over the entire length in the direction orthogonal to the paper surface of FIG. The shadow 102 is not formed on the display panel 101, and the appearance of characters and the like written on the display panel 101 is not impaired.

反射部材１０は、一例として表面に光沢のある白色の樹脂平板の所定の位置にプレス加工等によって形成した折り曲げ線で折り曲げて所定の形状にしたものである。図３（Ｂ）に示す例では、反射部材１０は、先端部から基端部までが平面状の２側面を有する三角形の断面形状を呈しているが、２側面が内側に凸となる形状に湾曲又は屈曲していてもよい。 As an example, the reflecting member 10 is formed into a predetermined shape by being bent at a predetermined position of a glossy white resin flat plate on a surface by a folding line formed by pressing or the like. In the example shown in FIG. 3B, the reflecting member 10 has a triangular cross-sectional shape having two planar side surfaces from the distal end portion to the proximal end portion, but the two side surfaces are convex inward. It may be curved or bent.

図４（Ａ）〜（Ｃ）は、この発明の実施形態に係る反射部材の組立工程を示す図である。反射部材１０は、一例として表面に光沢のある白色の樹脂平板を、プレス加工によって長尺状に打ち抜いて形成される。このとき、反射部材１０には、図４（Ａ）に示すように、長手方向（矢印Ｙ方向）に平行な主折り曲げ線２０、第１〜第４の折り曲げ線２１〜２４、孔部３０、係合片４０、延出部１５，１６及び切欠き部１７，１８が同時に形成される。 4 (A) to 4 (C) are diagrams showing an assembling process of the reflecting member according to the embodiment of the present invention. For example, the reflecting member 10 is formed by punching a white resin flat plate having a glossy surface into a long shape by pressing. At this time, as shown in FIG. 4A, the reflecting member 10 has a main fold line 20 parallel to the longitudinal direction (arrow Y direction), first to fourth fold lines 21 to 24, a hole 30, Engagement piece 40, extension parts 15 and 16, and notch parts 17 and 18 are formed simultaneously.

折り曲げ線２０〜２４は、反射部材１０の表面側から裏面側に達しない切り込みによって形成する。孔部３０は、矢印Ｙ方向の幅が異なる第１孔部３１と第２孔部３２とで構成され、反射部材１０の表面側から裏面側に達する打ち抜きによって形成する。係合片４０は、矢印Ｙ方向の幅が異なる第１係合部３１と第２係合３２とで構成され、反射部材１０の表面側から裏面側に達する切り込みによって形成する。係合片３０及び孔部４０がこの発明の係合対を構成する。 The fold lines 20 to 24 are formed by cutting that does not reach the back surface side from the front surface side of the reflecting member 10. The hole 30 is composed of a first hole 31 and a second hole 32 having different widths in the arrow Y direction, and is formed by punching from the front surface side to the back surface side of the reflecting member 10. The engagement piece 40 includes a first engagement portion 31 and a second engagement 32 having different widths in the arrow Y direction, and is formed by a notch reaching from the front surface side to the back surface side of the reflection member 10. The engagement piece 30 and the hole 40 constitute an engagement pair of the present invention.

延出部１５，１６は、反射部材１０のＹ方向に平行な両側面の互いに対向する位置に、矢印Ｙ方向に沿って所定の間隔で形成する。孔部３０及び係合片４０は、延出部１５，１６内に形成する。切欠き１７，１８は、一例として反射部材１０が装着される壁面２０４（図３参照。）に取り付けられた固定ネジとの干渉を避けるべく設けられている。壁面２０４に反射部材１０を装着する際に反射部材１０に干渉する部材が壁面２０４に無い場合には、切欠き１７，１８は省略できる。 The extending portions 15 and 16 are formed at predetermined intervals along the arrow Y direction at opposite positions on both side surfaces parallel to the Y direction of the reflecting member 10. The hole 30 and the engagement piece 40 are formed in the extending portions 15 and 16. As an example, the notches 17 and 18 are provided to avoid interference with a fixing screw attached to a wall surface 204 (see FIG. 3) on which the reflecting member 10 is mounted. When the wall member 204 has no member that interferes with the reflecting member 10 when the reflecting member 10 is mounted on the wall surface 204, the notches 17 and 18 can be omitted.

図４（Ｂ）に示すように、反射部材１０は、折り曲げ線２０〜２４で裏面側に向けて折り曲げる。折り曲げ線２４は、係合片４０内には形成されていない。このため、延出部１６を折り曲げ線２４で底面１４から裏面側に折り曲げた際にも、係合片４０は底面１４と面一の状態を保つ。 As shown in FIG. 4 (B), the reflecting member 10 is bent toward the back side along the fold lines 20 to 24. The fold line 24 is not formed in the engagement piece 40. For this reason, even when the extending portion 16 is bent from the bottom surface 14 to the back surface side along the folding line 24, the engagement piece 40 is kept flush with the bottom surface 14.

さらに、底面１３の端面と底面１４の端面とを近接させていき、図４（Ｃ）に示すように、側面１１，１２及び底面１３，１４の内側で、延出部１５の表面と延出部１６の表面とを当接させる。底面１３と底面１４との間には、延出部１５，１６及び切欠き１７，１８の形成位置を除く範囲に、間隙５１が形成される。この間隙５１の矢印Ｙ方向の幅は、壁面２０４の幅に略等しくされている。また、切欠き１７，１８は、底面１３と底面１４との間に空間５２を形成する。 Further, the end surface of the bottom surface 13 and the end surface of the bottom surface 14 are brought close to each other, and as shown in FIG. 4C, the surface of the extending portion 15 extends to the inside of the side surfaces 11 and 12 and the bottom surfaces 13 and 14. The surface of the part 16 is brought into contact. A gap 51 is formed between the bottom surface 13 and the bottom surface 14 in a range excluding the positions where the extending portions 15 and 16 and the notches 17 and 18 are formed. The width of the gap 51 in the arrow Y direction is substantially equal to the width of the wall surface 204. Further, the notches 17 and 18 form a space 52 between the bottom surface 13 and the bottom surface 14.

係合片４０を孔部３０内に反射部材１０の底面側から内部に挿入すると、係合片４０が孔部３０に係合し、反射部材１０は、一様な三角形断面形状を維持する。 When the engaging piece 40 is inserted into the hole 30 from the bottom surface side of the reflecting member 10, the engaging piece 40 engages with the hole 30 and the reflecting member 10 maintains a uniform triangular cross-sectional shape.

図５は、反射部材に形成された凹部及び係合片の底面側から見た斜視図である。係合片４０は、底面１４に対して延出部１６を裏面側に折り曲げることで延出部１６と分離し、矢印Ｙ方向について幅Ｌ１の第１係合部４１と幅Ｌ２の第２係合部４２とで構成されている。矢印Ｙ方向に直交する矢印Ｘ方向について、第１係合部４１は長さＬ３にされており、第２係合部４２は長さＬ４にされている。第１係合部４１の開放端側は、傾斜面４１１が形成されている。 FIG. 5 is a perspective view of the concave portion formed on the reflecting member and the bottom surface side of the engaging piece. The engaging piece 40 is separated from the extending portion 16 by bending the extending portion 16 to the back surface side with respect to the bottom surface 14, and the first engaging portion 41 having the width L1 and the second engaging portion having the width L2 in the arrow Y direction. It is comprised with the joint part 42. FIG. In the arrow X direction orthogonal to the arrow Y direction, the first engagement portion 41 has a length L3, and the second engagement portion 42 has a length L4. An inclined surface 411 is formed on the open end side of the first engagement portion 41.

孔部３０は、底面１３と延出部１５とに連続して形成されており、矢印Ｙ方向について幅Ｌ６の第１孔部３１と幅Ｌ７の第２孔部３２とで構成されている。矢印Ｘ方向について、第１孔部３１は長さＬ８にされており、第２孔部３２は長さＬ９にされている。第２孔部３２の第１孔部３１側の側面には、傾斜面３１１が形成されている。 The hole 30 is formed continuously from the bottom surface 13 and the extension 15, and includes a first hole 31 having a width L 6 and a second hole 32 having a width L 7 in the arrow Y direction. In the direction of the arrow X, the first hole portion 31 has a length L8, and the second hole portion 32 has a length L9. An inclined surface 311 is formed on the side surface of the second hole portion 32 on the first hole portion 31 side.

矢印Ｘ方向及び矢印Ｙ方向に直交する矢印Ｚ方向について、係合片４０は反射部材１０の全体と同様に厚さＬ５にされており、第２孔部３２は深さＬ１０にされている。 In the arrow Z direction orthogonal to the arrow X direction and the arrow Y direction, the engagement piece 40 has a thickness L5 as in the entire reflecting member 10, and the second hole 32 has a depth L10.

上記の各部の寸法は、少なくともＬ１≦Ｌ６、Ｌ２≦Ｌ７、Ｌ５≦Ｌ８、Ｌ５≦Ｌ１０、Ｌ９≦Ｌ４の関係にされている。 The dimensions of the above parts are at least in the relationship of L1 ≦ L6, L2 ≦ L7, L5 ≦ L8, L5 ≦ L10, and L9 ≦ L4.

図６は、組立後の反射部材の断面図である。反射部材１０における凹部３０及び係合片４０の各部の寸法が図５に示す関係にされているため、係合片４０を反射部材１０の底面側から孔部３０を経由して反射部材１０の内部に挿入すると、第１係合部の先端が底面１３の裏面（内側面）に当接する。また、第２係合部４２は、第２凹部３２内に位置する。さらに、第１延出部４１の底面１４側の側面が、延出部１５の裏面に当接する。 FIG. 6 is a cross-sectional view of the reflecting member after assembly. Since the dimensions of the respective portions of the recess 30 and the engagement piece 40 in the reflection member 10 are in the relationship shown in FIG. 5, the engagement piece 40 is connected to the reflection member 10 from the bottom surface side of the reflection member 10 through the hole 30. When inserted into the interior, the tip of the first engaging portion abuts against the back surface (inner surface) of the bottom surface 13. Further, the second engagement portion 42 is located in the second recess 32. Further, the side surface on the bottom surface 14 side of the first extension portion 41 contacts the back surface of the extension portion 15.

これらにより、延出部１５の表面と延出部１６の表面との当接状態が維持され、図５に示した矢印Ｘ，Ｙ，Ｚの３方向について、底面１３及び底面１４が互いに離間する方向へ移動することを規制できる。このため、反射部材１０は断面形状を自己保持し、作業者は、反射部材１０の形状を維持することなく、図４（Ｃ）に示した間隙５１に壁面２０４を貫通かせることで、反射部材１０を壁面２０４に容易に装着することができる。なお、反射部材１０は、底面１３，１４をカバー２０３に接着剤や両面テープを介して接着され、壁面２０４に対する装着状態が維持される。 Accordingly, the contact state between the surface of the extending portion 15 and the surface of the extending portion 16 is maintained, and the bottom surface 13 and the bottom surface 14 are separated from each other in the three directions of arrows X, Y, and Z shown in FIG. It is possible to regulate movement in the direction. Therefore, the reflecting member 10 self-holds the cross-sectional shape, and the operator allows the wall surface 204 to penetrate the gap 51 shown in FIG. 4C without maintaining the shape of the reflecting member 10. 10 can be easily attached to the wall surface 204. The reflecting member 10 has the bottom surfaces 13 and 14 bonded to the cover 203 via an adhesive or double-sided tape, and the mounting state on the wall surface 204 is maintained.

第２孔部３２には傾斜面３１１が形成されており、第１係合部４１には傾斜面４１１が形成されているため、係合片４０を孔部３０に容易に貫通させることができる。反射部材１０の素材や寸法形状によって係合片４０を孔部３０に容易に貫通させることができることを条件に、傾斜面３１１及び４１１を省略できる。また、傾斜面３１１及び４１１に代えて円弧形状とすることもできる。 Since the inclined surface 311 is formed in the second hole portion 32 and the inclined surface 411 is formed in the first engaging portion 41, the engaging piece 40 can be easily passed through the hole portion 30. . The inclined surfaces 311 and 411 can be omitted on the condition that the engagement piece 40 can be easily penetrated through the hole 30 depending on the material and dimensions of the reflecting member 10. Further, instead of the inclined surfaces 311 and 411, an arc shape may be used.

図７は、この発明の別の実施形態に係る反射部材の断面図である。反射部材１１０は、側面１１，１２のそれぞれと底面１３，１４のそれぞれとの間に、斜面１３１，１４１を形成したものである。底面１３，１４には、延出部１５，１６とともに孔部３０及び係合片４０が形成されている。斜面１３１，１４１は、壁面２０４に設けられたカバー２０３の斜面に当接する。 FIG. 7 is a cross-sectional view of a reflecting member according to another embodiment of the present invention. The reflecting member 110 has slopes 131 and 141 formed between the side surfaces 11 and 12 and the bottom surfaces 13 and 14, respectively. A hole 30 and an engagement piece 40 are formed on the bottom surfaces 13 and 14 together with the extending portions 15 and 16. The slopes 131 and 141 are in contact with the slope of the cover 203 provided on the wall surface 204.

反射部材１１０は、斜面１３１，１４１を備えることでカバー２０３との接合面積が拡大するとともに、弾性力によって斜面１３１，１４１をカバー２０３に圧接させることができ、壁面２０４に対する装着状態をより確実に維持できる。 Since the reflecting member 110 includes the slopes 131 and 141, the joint area with the cover 203 is increased, and the slopes 131 and 141 can be pressed against the cover 203 by elastic force, so that the mounting state with respect to the wall surface 204 can be more reliably performed. Can be maintained.

なお、反射部材１１０には、底面１３，１４と斜面１３１，１４１との間に、裏面側から折り曲げ線１１１，１１２を形成する。 In addition, bend lines 111 and 112 are formed on the reflecting member 110 from the back surface side between the bottom surfaces 13 and 14 and the inclined surfaces 131 and 141.

また、上述の反射部材１０及び１１０は、表示ユニット１００の光源装置２００だけでなく、内部に端面を露出して位置する壁面を備えた装置に同様に適用することができる。 Moreover, the above-described reflecting members 10 and 110 can be similarly applied not only to the light source device 200 of the display unit 100 but also to a device including a wall surface that is located with an end face exposed inside.
