Characterized by comprising
Is.

この表示装置は、側面部材によって取り付け部材側方が覆われ、保護部材によって側方を除く他の四方が覆われているため、外部から取り付け部材が視認し難くい。また、側面部材や保護部材の外面が平坦面である場合には、平坦な外面が外部から視認されることになるため、全体としてすっきりとした外観を有することとなり、優れた美観を演出することができる。このとき、保護部材は保護部材の内側に固定された固定部材によって側面部材を介して取り付け部材に固定されているため、固定部材と取り付け部材とをねじ等で固定した場合であっても、固定部材やねじ等の固定具が外部から視認される可能性を未然に低減し、全体としてシンプルな印象を与えることができる。   In this display device, the side of the attachment member is covered by the side member, and the other four sides except the side are covered by the protection member, so that the attachment member is difficult to visually recognize from the outside. Also, when the outer surface of the side member or the protective member is a flat surface, the flat outer surface will be visually recognized from the outside, so that it will have a clean appearance as a whole and produce an excellent aesthetic appearance. Can do. At this time, since the protective member is fixed to the mounting member via the side member by the fixing member fixed to the inner side of the protective member, the fixing member is fixed even if the fixing member and the mounting member are fixed with screws or the like. The possibility that fixtures such as members and screws are visually recognized from the outside is reduced, and a simple impression can be given as a whole.

本発明の表示装置において、前記固定部材は、雄ねじと、前記雄ねじの軸が通過する貫通孔を有する板状部材と、からなり、前記側面部材は、前記雄ねじが螺合するねじ孔を有し、前記固定部材は、前記雄ねじが前記ねじ孔に螺合することにより、前記保護部材を前記側面部材に着脱可能に固定することを特徴とするものであってもよい。こうすれば、側面部材に設けられたねじ孔に固定部材に設けられた貫通孔を通過する雄ねじを螺合することにより、保護部材と側面部材とが固定部材によって着脱可能に固定される。こうすることにより、保護部材が側面部材を介して取り付け部材に固定されるため、保護部材の外観がすっきりとした印象を与え、優れた美観を演出することができる。   In the display device of the present invention, the fixing member includes a male screw and a plate-like member having a through-hole through which the shaft of the male screw passes, and the side member has a screw hole into which the male screw is screwed. The fixing member may be characterized in that the protective member is detachably fixed to the side member when the male screw is screwed into the screw hole. If it carries out like this, a protection member and a side member will be detachably fixed by a fixing member by screwing the male screw which passes the through-hole provided in the fixing member to the screw hole provided in the side member. By carrying out like this, since a protection member is fixed to an attachment member via a side member, the appearance of a protection member can give a clean impression and can produce outstanding aesthetics.

An engagement recess 72 is provided on the side, and a first screw hole 74 and a second screw hole 76 are provided on the front side and the rear side in order from the inside toward the side. When the side member 70 is attached to the attachment member 30, the engaging recess 72 is positioned by engaging with the locking portion 38, and the screw hole 39 and the first screw hole 74 are fixed with a male screw (not shown). By doing so, the side member 70 and the attachment member 30 can be firmly fixed.

保護部材80は、図2及び図3に示すように、保護部材80の上方側であって、内側面に固定部材81が、保護部材80の前方側及び後方側の外面80aには一対の雄ねじ回転孔86が、それぞれ設けられた金属製のカバー部材である。この保護部材80を、図2に示すように取り付け部材30の前方側及び後方側からそれぞれ側面部材70を介して取り付けることにより、保護部材80によって取り付け部材30が覆われ、取り付け構造が外側から視認されにくく、優れた美観を提供することができる。また、雄ねじ回転孔86は、直径が後述する雄ねじ84の頭の直径よりも短く、雄ねじ84のねじ穴の直径よりも長く形成されている。このため、雄ねじ84が雄ねじ回転孔86から脱落する可能性を未然に低減するとともに、雄ねじ回転孔86を介して雄ねじ84が視認し難くなるため、優れた美観を演出することができる。   As shown in FIGS. 2 and 3, the protection member 80 is above the protection member 80, and has a fixing member 81 on the inner surface and a pair of male screws on the front and rear outer surfaces 80 a of the protection member 80. The rotation holes 86 are metal cover members provided respectively. 2, the attachment member 30 is covered by the protection member 80 from the front side and the rear side of the attachment member 30 as shown in FIG. It is hard to be done and can provide an excellent aesthetic. The male screw rotation hole 86 has a diameter shorter than the diameter of the head of the male screw 84, which will be described later, and longer than the diameter of the screw hole of the male screw 84. For this reason, the possibility that the male screw 84 falls off from the male screw rotation hole 86 is reduced, and the male screw 84 becomes difficult to visually recognize through the male screw rotation hole 86, so that an excellent aesthetic appearance can be produced.

固定部材81は、図2及び図3に示すように、横板82aと貫通孔82cを有する縦板82bとが略直角に連接された金属製の板状部材82と、雄ねじ84と、を備えている。この雄ねじ84は、貫通孔82cに軸の一部が貫通した状態で雄ねじ84の頭が雄ねじ回転孔86の方向を向くように挿入されている。このとき、横板82aと縦板82bとは略直角に形成されているため、横板82aを保護部材80の上方の内面に固定した場合には、縦板82bと保護部材80の前方側及び後方側の外面80aとが略平行になる。このため、縦板82bに設けられた貫通孔82cに挿入された雄ねじ84のねじ孔と保護部材80に設けられた雄ねじ回転孔86とが略平行となるため、雄ねじ回転孔86にドライバー等を挿入して雄ねじ84を回しやすい。また、保護部材80の前方側及び後方側の内面80bと縦板82bとの間隔が、雄ねじ84の頭の厚みと略同一となる位置に固定部材81は固定されている。このため、雄ねじ84が脱落する可能性を未然に低減することができる。   As shown in FIGS. 2 and 3, the fixing member 81 includes a metal plate member 82 in which a horizontal plate 82 a and a vertical plate 82 b having a through hole 82 c are connected at a substantially right angle, and a male screw 84. ing. The male screw 84 is inserted so that the head of the male screw 84 faces the direction of the male screw rotation hole 86 with a part of the shaft passing through the through hole 82c. At this time, since the horizontal plate 82a and the vertical plate 82b are formed at substantially right angles, when the horizontal plate 82a is fixed to the inner surface above the protection member 80, the front side of the vertical plate 82b and the protection member 80 and The outer surface 80a on the rear side is substantially parallel. For this reason, since the screw hole of the male screw 84 inserted in the through hole 82c provided in the vertical plate 82b and the male screw rotation hole 86 provided in the protection member 80 are substantially parallel, a screwdriver or the like is inserted into the male screw rotation hole 86. It is easy to insert and rotate the male screw 84. The fixing member 81 is fixed at a position where the distance between the front and rear inner surfaces 80b of the protective member 80 and the vertical plate 82b is substantially the same as the thickness of the head of the male screw 84. For this reason, it is possible to reduce the possibility of the male screw 84 falling off.

次に、表示装置20を天井又は壁面に取り付ける取り付け方法について、図4から図6を用いて説明する。ここで、図4から図6は、表示装置20を天井又は壁面に取り付ける際の取り付け方法を説明した説明図であり、図4は、取り付け部材30に吊り下げ部材40を吊り下げる前後の状態を、図5は、取り付け部材30に側面部材70を取り付ける前後の状態を、図6は、保護部材80を取り付ける様子を、それぞれ示している。   Next, a method of attaching the display device 20 to the ceiling or wall surface will be described with reference to FIGS. Here, FIG. 4 to FIG. 6 are explanatory views for explaining the attachment method when attaching the display device 20 to the ceiling or the wall surface, and FIG. 4 shows the state before and after the suspension member 40 is suspended from the attachment member 30. 5 shows a state before and after attaching the side member 70 to the attachment member 30, and FIG. 6 shows a state where the protection member 80 is attached.

表示装置20を天井又は壁面に取り付ける際には、まず、接続部34を介して天井又は壁面に取り付け部材30を固定する。このとき、表示装置20と天井面又は壁面との間に空間がある場合には、接続部34を保護カバー35で覆う。こうすることにより、接続部34や図示しない電源コード等が外部から視認される可能性を低減し、優れた美観を演出することができる。なお、表示装置20を天井面又は壁面に近い位置に設置する場合には、保護カバー35を設ける必要は無い。   When attaching the display device 20 to the ceiling or the wall surface, first, the attachment member 30 is fixed to the ceiling or the wall surface via the connection portion 34. At this time, when there is a space between the display device 20 and the ceiling surface or the wall surface, the connecting portion 34 is covered with the protective cover 35. By doing so, it is possible to reduce the possibility that the connecting portion 34, a power cord (not shown) and the like are visually recognized from the outside, and produce an excellent aesthetic appearance. In addition, when installing the display apparatus 20 in the position close | similar to a ceiling surface or a wall surface, it is not necessary to provide the protective cover 35. FIG.

次に、予め天井面又は壁面に取り付けられた取り付け部材30に吊り下げ部材40を吊り下げ方法について、図4を用いて説明する。ここで、図4Aは、取り付け部材30に吊り下げ部材40を吊り下げる前の状態を、図4Bは、取り付け部材30に吊り下げ部材40を吊り下げた状態を、それぞれ示している。吊り下げ部材40を取り付け部材30に吊り下げる際には、挿入凹部42に突出部36aを、固定凹部44に突出部36bをそれぞれ挿入し、吊り下げ部材40を図4中の矢印の方向に移動する。こうすることにより、突出部36a及び突出部36bがそれぞれ挿入凹部42及び固定凹部44の奥に移動し、自重により吊り下げ部材30は下方向に押圧される。このとき、挿入凹部42の奥部の上方側に凹みを有しているため、この凹みに突出部36aが引っ掛かることになり、挿入凹部42から突出部26aが脱落する可能性を低減することができる。また、固定凹部44は、L字形状の凹部に突出部36bが移動すると、上方向への移動が規制されるため、固定凹部44から突出部36bが脱落する可能性を未然に低減することができる。このように、重量の大きな導光板50が固定された吊り下げ部材40を先に取り付け部材30に吊り下げることにより、以後の取り付けの際に導光板50を別途支える必要が無いため、取り付け時の労力を低減し、安全性を高めることができる。   Next, a method for suspending the suspension member 40 from the attachment member 30 that is previously attached to the ceiling surface or wall surface will be described with reference to FIG. 4A shows a state before the suspension member 40 is suspended from the attachment member 30, and FIG. 4B shows a state where the suspension member 40 is suspended from the attachment member 30, respectively. When the suspension member 40 is suspended from the mounting member 30, the protrusion 36a is inserted into the insertion recess 42 and the protrusion 36b is inserted into the fixed recess 44, and the suspension member 40 is moved in the direction of the arrow in FIG. To do. By doing so, the protruding portion 36a and the protruding portion 36b move to the back of the insertion recessed portion 42 and the fixed recessed portion 44, respectively, and the suspension member 30 is pressed downward by its own weight. At this time, since there is a dent on the upper side of the back part of the insertion recess 42, the protrusion 36a is caught in this recess, and the possibility that the protrusion 26a falls off the insertion recess 42 can be reduced. it can. Further, since the fixed recess 44 is restricted from moving upward when the protrusion 36b moves to the L-shaped recess, the possibility of the protrusion 36b dropping from the fixed recess 44 can be reduced. it can. In this way, since the suspension member 40 to which the heavy light guide plate 50 is fixed is first suspended from the attachment member 30, it is not necessary to separately support the light guide plate 50 during subsequent attachment. Labor can be reduced and safety can be increased.

続いて、吊り下げ部材40が吊り下げられた取り付け部材30に側面部材70を固定する固定方法について、図5を用いて説明する。ここで、図5Aは、取り付け部材30に側面部材70を取り付ける前の状態を、図5Bは、取り付け部材30に側面部材70を取り付けた状態を、それぞれ示している。図5Aに示すように、取り付け部材30に側面部材70を取り付ける際には、取り付け部材30の側方から、側面部材70をそれぞれ図5中の矢印の方向に移動し、それぞれ側面部材70の間に嵌め込む。具体的には、図5Bに示すように、取り付け部材30の前方側及び後方側に接続部34を中心に対向して左方側及び右方側にそれぞれ設けられた係止部38と側面部材70の端部に設けられた係合凹部72とが係合する位置まで取り付け部材30に側面部材70を嵌め込む。こうすることにより、側面部材70を取り付け部材30の所定の位置に位置決めすることができる。このとき、側面部材70に設けられた第一ねじ孔74とねじ孔39とが連通する位置に位置決めされるため、図示しない雄ねじを用いることで、側面部材70と取り付け部材30とを固定することができる。こうすることにより、側面部材70によって吊り下げ部材40の側方への移動が規制されることになるため、側面部材70と同時に吊り下げ部材40も取り付け部材30に固定される。   Next, a fixing method for fixing the side member 70 to the attachment member 30 from which the suspension member 40 is suspended will be described with reference to FIG. Here, FIG. 5A shows a state before the side member 70 is attached to the attachment member 30, and FIG. 5B shows a state where the side member 70 is attached to the attachment member 30. As shown in FIG. 5A, when attaching the side member 70 to the attachment member 30, the side member 70 is moved from the side of the attachment member 30 in the direction of the arrow in FIG. Fit into. Specifically, as shown in FIG. 5B, the locking portion 38 and the side member provided on the left side and the right side, respectively, facing the connection portion 34 at the front side and the rear side of the mounting member 30. The side member 70 is fitted into the attachment member 30 to a position where the engagement recess 72 provided at the end portion of the 70 is engaged. By doing so, the side member 70 can be positioned at a predetermined position of the attachment member 30. At this time, since the first screw hole 74 provided in the side member 70 and the screw hole 39 are positioned to communicate with each other, the side member 70 and the attachment member 30 are fixed by using a male screw (not shown). Can do. By doing so, the lateral movement of the suspension member 40 is restricted by the side member 70, so that the suspension member 40 is also fixed to the attachment member 30 simultaneously with the side member 70.

最後に、取り付け部材30に側面部材70を介して保護部材80を取り付ける取り付け方法について図6を用いて説明する。ここで、図6Aは、側面部材70に保護部材80を取り付ける前の状態を示す斜視図であり、図6Bは、側面部材70に保護部材80が固定された状態で雄ねじ回転孔86を含む平面で切断した断面図である。側面部材70に保護部材80に取り付ける際には、図6A中の矢印で示すように、取り付け部材30の前方側及び後方側から、それぞれ保護部材80を取り付ける。こうすることにより、保護部材80によって、取り付け部材30の上方側、前方側、後方側及び導光板50を除いた下方側が覆われ、側面部材70によって取り付け部材30の側方側が覆われるため、取り付け部材30が外部から視認されない。このとき、取り付け部材30に取り付けた雄ねじ等の取り付け部も外部から視認されないため、全体としてすっきりとした印象を与え、優れた美観を演出することができる。   Finally, an attachment method for attaching the protection member 80 to the attachment member 30 via the side member 70 will be described with reference to FIG. 6A is a perspective view showing a state before the protective member 80 is attached to the side member 70, and FIG. 6B is a plane including the male screw rotation hole 86 in a state where the protective member 80 is fixed to the side member 70. It is sectional drawing cut | disconnected by. When attaching to the side member 70 to the protection member 80, as shown by the arrows in FIG. 6A, the protection member 80 is attached from the front side and the rear side of the attachment member 30, respectively. By doing so, the protective member 80 covers the upper side, the front side, the rear side, and the lower side of the mounting member 30 except for the light guide plate 50, and the side member 70 covers the side of the mounting member 30. The member 30 is not visually recognized from the outside. At this time, since an attachment portion such as a male screw attached to the attachment member 30 is not visually recognized from the outside, a clean impression can be given as a whole and an excellent aesthetic appearance can be produced.

ここで、取り付け部材30に側面部材70を介して保護部材80が固定された状態について、図6Bを用いて更に詳しく説明する。取り付け部材30に側面部材70を介して保護部材80を取り付ける際には、図6Bに示すように、固定部材81を側面部材70に取り付けることで、側面部材70を介して取り付け部材30と保護部材80とを固定する。具体的には、保護部材80に設けられた雄ねじ回転孔86にドライバー等を挿入し、固定部材81に設けられた雄ねじ84を回転させる。こうすることにより、雄ねじ84が側面部材70に設けられたねじ孔76と螺合し、保護部材80と側面部材70とが固定される。   Here, the state in which the protective member 80 is fixed to the attachment member 30 via the side member 70 will be described in more detail with reference to FIG. 6B. When the protective member 80 is attached to the attachment member 30 via the side member 70, the fixing member 81 is attached to the side member 70 as shown in FIG. 80 is fixed. Specifically, a screwdriver or the like is inserted into the male screw rotation hole 86 provided in the protection member 80, and the male screw 84 provided in the fixing member 81 is rotated. By doing so, the male screw 84 is screwed into the screw hole 76 provided in the side member 70, and the protective member 80 and the side member 70 are fixed.

以上詳述した本実施の形態の表示装置20によれば、取り付け部材30の側方を取り付け部材30に固定された側面部材70が覆い、取り付け部材30の前方、後方、上方及び下方の導光板50を有しない部分を側面部材70に固定された保護部材80が覆うことにより、取り付け部材30に吊り下げられた吊り下げ部材40及び取り付け部材30と側面部材70とを固定する図示しない雄ねじが外部から視認されることを防止することができるため、表示装置20の外観を全体としてすっきりとした印象を演出し、優れた美観を演出することができる。   According to the display device 20 of the present embodiment described in detail above, the side member 70 fixed to the attachment member 30 covers the side of the attachment member 30, and the front, rear, upper and lower light guide plates of the attachment member 30 are covered. The protective member 80 fixed to the side member 70 covers the portion not having 50, so that the suspension member 40 suspended from the attachment member 30 and the male screw (not shown) that fixes the attachment member 30 and the side member 70 are external. Therefore, it is possible to prevent the display device 20 from being visually recognized, and thus it is possible to produce a clean impression as a whole and to produce an excellent aesthetic appearance.

また、保護部材80は、保護部材80の内側に設けられた固定部材81によって側面部材70に固定される。この側面部材70は取り付け部材30に固定されているため、保護部材80は側面部材70を介して取り付け部材30に固定されることになる。このため、表示装置20の外部から視認されることなく保護部材80を取り付け部材30に固定することができる。こうすることにより、表示装置20の外観を全体としてすっきりとした印象を演出し、優れた美観を演出することができる。このとき、固定部材81と側面部材70とは、雄ねじ84を回転させるという簡単な操作で着脱することができるため、着脱時の労力を低減することができる。   Further, the protection member 80 is fixed to the side member 70 by a fixing member 81 provided inside the protection member 80. Since the side member 70 is fixed to the attachment member 30, the protection member 80 is fixed to the attachment member 30 via the side member 70. For this reason, the protection member 80 can be fixed to the attachment member 30 without being visually recognized from the outside of the display device 20. By doing so, it is possible to produce a clean impression as a whole of the display device 20 and produce an excellent aesthetic appearance. At this time, the fixing member 81 and the side surface member 70 can be attached and detached by a simple operation of rotating the male screw 84, so that labor during attachment and detachment can be reduced.

更に、雄ねじ84が配置される際、雄ねじ84のねじ穴と対向する位置における保護部材80の前方側及び後方側の外面80aには雄ねじ回転孔86が設けられているため、雄ねじ回転孔86にドライバー等を挿入することで、容易に雄ねじ84を回転させることができる。加えて、雄ねじ回転孔86の直径は、雄ねじ84の頭の直径よりも短く形成されているため、雄ねじ84が雄ねじ回転孔86から脱落する可能性を未然に低減すると共に、雄ねじ84が外部に露出している場合と比較して、雄ねじ84が外部から視認され難くし、すっきりとした印象を演出し、優れた美観を演出することができる。   Furthermore, when the male screw 84 is disposed, the male screw rotation hole 86 is provided in the outer surface 80a on the front side and the rear side of the protective member 80 at a position facing the screw hole of the male screw 84. The male screw 84 can be easily rotated by inserting a screwdriver or the like. In addition, since the diameter of the male screw rotation hole 86 is shorter than the diameter of the head of the male screw 84, the possibility of the male screw 84 falling off from the male screw rotation hole 86 is reduced, and the male screw 84 is exposed to the outside. Compared to the exposed case, the male screw 84 is less likely to be visually recognized from the outside, producing a clean impression and producing an excellent aesthetic appearance.

更にまた、固定部材81は、横板82aと縦板82bとが略直角に連接された板状部材82によって、保護部材80の上方の内面に固定されているため、貫通孔82cに雄ねじ84が配置された際、雄ねじ84のねじ穴と保護部材80の前方側及び後方側の外面80aに設けられた雄ねじ回転孔86とが略平行に位置することになる。こうすることにより、雄ねじ回転孔86にドライバー等を挿入して雄ねじ84を回転させる際に、容易に回転させることができる。   Furthermore, since the fixing member 81 is fixed to the upper inner surface of the protective member 80 by a plate-like member 82 in which the horizontal plate 82a and the vertical plate 82b are connected at a substantially right angle, the male screw 84 is provided in the through hole 82c. When arranged, the screw hole of the male screw 84 and the male screw rotation hole 86 provided in the outer surface 80a on the front side and the rear side of the protection member 80 are positioned substantially in parallel. By doing so, when a screwdriver or the like is inserted into the male screw rotation hole 86 and the male screw 84 is rotated, it can be easily rotated.

そして、導光板50の固定された吊り下げ部材40を取り付け部材30の前方側及び後方側にそれぞれ設けられた突出部36a及び突出部36bに吊り下げることにより、取り付け部材30に側面部材70を固定する際や、側面部材70に保護部材80を固定する際に、重量の大きな導光板50を支える必要が無い。このため、表示装置20を組み立てる際の労力を低減することができる。このとき、吊り下げ部材40は、吊り下げ部材40に設けられた挿入凹部42及び固定凹部44に突出部36a及び突出部36bをそれぞれ挿入するという簡単な操作で吊り下げ部材40を取り付け部材30に吊り下げることができるため、表示装置20を組み立てる際の労力が少ない。   Then, the side member 70 is fixed to the attachment member 30 by suspending the suspension member 40 to which the light guide plate 50 is fixed on the protrusion 36a and the protrusion 36b provided on the front side and the rear side of the attachment member 30, respectively. When the protective member 80 is fixed to the side member 70, the heavy light guide plate 50 need not be supported. For this reason, the effort at the time of assembling the display apparatus 20 can be reduced. At this time, the suspension member 40 can be attached to the attachment member 30 by a simple operation of inserting the protrusion 36a and the protrusion 36b into the insertion recess 42 and the fixed recess 44 provided in the suspension member 40, respectively. Since it can be hung, the labor for assembling the display device 20 is small.

そして更に、挿入凹部42は上方に凹みを有する直線形状に、固定凹部44は上方側が開放されたL字形状に形成されているため、挿入凹部42及び固定凹部44に突出部36a及び突出部36bが一度係合した場合には、重力により係止されることになり、吊り下げ部材40が取り付け部材30から脱落する可能性を未然に低減することができる。   Further, since the insertion recess 42 is formed in a linear shape having a recess on the upper side, and the fixing recess 44 is formed in an L shape with the upper side opened, the protrusions 36 a and 36 b are formed in the insertion recess 42 and the fixing recess 44. Is engaged by gravity, it is possible to reduce the possibility that the suspension member 40 will fall off the attachment member 30 in advance.

そして更にまた、吊り下げ部材40は、側面部材70及び保護部材80によって表示装置20の内側に格納されることになるため、外部から視認されにくい。こうすることにより、表示装置20の全体として整然とした優れた美観を演出することができる。   Furthermore, since the suspension member 40 is stored inside the display device 20 by the side member 70 and the protection member 80, the suspension member 40 is not easily seen from the outside. By doing so, it is possible to produce an excellent and tidy appearance as a whole of the display device 20.

加えて、取り付け部材30に吊り下げ部材40を吊り下げた際、一対の吊り下げ部材40と取り付け部材30及び導光板50に囲まれた領域に光源部材60が配置されるため、取り付け部材30を吊り下げ部材40に吊り下げるという一連の操作の中で、光源部材60を配置することができる。このため、光源部材60を配置するために新たな労力を必要としない。   In addition, when the suspension member 40 is suspended from the attachment member 30, the light source member 60 is disposed in a region surrounded by the pair of suspension members 40, the attachment member 30, and the light guide plate 50. The light source member 60 can be arranged in a series of operations of hanging on the hanging member 40. For this reason, a new effort is not required to arrange the light source member 60.

なお、本発明は上述した実施の形態に何ら限定されることはなく、本発明の技術的範囲に属する限り種々の態様で実施し得ることはいうまでもない。   In addition, this invention is not limited to embodiment mentioned above at all, and as long as it belongs to the technical scope of this invention, it cannot be overemphasized that it can implement with a various aspect.

例えば、上述した実施の形態では、表示装置20を1つの取り付け部材30で取り付けるものとしたが、図7に示すように、2つの取り付け部材30で取り付けても良いし、3つ以上の取り付け部材30で取り付けても良い。導光板50の大きさに合わせて、取り付け部材30を使用する数は適宜選択することができる。   For example, in the embodiment described above, the display device 20 is attached by one attachment member 30, but as shown in FIG. 7, it may be attached by two attachment members 30, or three or more attachment members. It may be attached at 30. According to the size of the light guide plate 50, the number of the attachment members 30 to be used can be selected as appropriate.

上述した実施の形態では、導光板50は透過性を有するメタクリル樹脂製の板であるものとしたが、透過性を有する素材であればメタクリル樹脂製に限定されるものでなく、メチルメタクリレートやエチルメタクリレート等のメタクリル樹脂意外にも、例えば、メチルアクリレート、エチルアクリレート等のアクリル製樹脂、ABS樹脂、ポリカーボネート、ポリエチレン等の種々の素材を用いることができる。いずれの場合であっても、上述した実施の形態と同様の効果が得られる。   In the above-described embodiment, the light guide plate 50 is a plate made of methacrylic resin having transparency. However, the light guide plate 50 is not limited to methacrylic resin as long as the material has transparency, and methyl methacrylate or ethyl In addition to methacrylic resins such as methacrylate, various materials such as acrylic resins such as methyl acrylate and ethyl acrylate, ABS resins, polycarbonate, and polyethylene can be used. In any case, the same effect as the above-described embodiment can be obtained.

上述した実施形態にでは、一対の吊り下げ部材40を導光板50の両主面側に固定するものとしたが、導光板50の一方主面側又は両主面側の表面側に乳半板を配置し、導光板50と乳半板とを同時に固定しても良い。こうすれば、導光板50に設けられた拡散ドット52を外部から視認し難くし、全体としてより均一な光を照射することができる。また、上方が開放された導光板50が収納可能な大きさのケースに収納しても良い。この場合も、導光板50に設けられた拡散ドット52を外部から視認し難くし、全体としてより均一な光を照射することができる。   In the embodiment described above, the pair of suspension members 40 are fixed to both main surfaces of the light guide plate 50. However, the milk half plate is placed on one main surface side or both main surface sides of the light guide plate 50. The light guide plate 50 and the milk half plate may be fixed simultaneously. This makes it difficult to visually recognize the diffusing dots 52 provided on the light guide plate 50 from the outside, and more uniform light can be irradiated as a whole. Alternatively, the light guide plate 50 opened upward may be stored in a case that can be stored. Also in this case, it is difficult to visually recognize the diffusing dots 52 provided on the light guide plate 50 from the outside, and it is possible to irradiate more uniform light as a whole.

上述した実施の形態では、拡散ドット52は両主面側に設けられるものとしたが、一方主面側にのみ設けるものとしてもよい。この場合であっても、上述した実施の形態と同様の効果が得られる。このとき、拡散ドット52を形成した側に反射シートを設けても良い。こうすれば、拡散ドット52が形成された側に拡散された光を反射シートで反射することができるため、拡散ドット52が形成されていない側の主面からより明るい光を出射することができる。   In the above-described embodiment, the diffusing dots 52 are provided on both main surfaces, but may be provided only on one main surface. Even in this case, the same effect as the above-described embodiment can be obtained. At this time, a reflection sheet may be provided on the side where the diffusion dots 52 are formed. In this way, since the light diffused to the side where the diffusion dots 52 are formed can be reflected by the reflection sheet, brighter light can be emitted from the main surface on the side where the diffusion dots 52 are not formed. .

上述した実施の形態では、拡散ドット52の配置位置により、文字又は模様を表現するものとしたが、拡散ドット52に変えて、レーザー加工痕や超音波加工痕、切削加工痕等によって文字又は模様を表現しても良いし、これらを組み合わせて文字又は模様を表現しても良い。いずれの場合であっても、上述した実施の形態と同様の効果を得ることができる。   In the above-described embodiment, the character or pattern is expressed by the arrangement position of the diffusing dots 52. However, instead of the diffusing dots 52, the characters or patterns are changed by laser processing marks, ultrasonic processing marks, cutting marks, etc. May be expressed, or a character or a pattern may be expressed by combining these. In any case, the same effect as that of the above-described embodiment can be obtained.

上述した実施の形態では、拡散ドット52は、四角錐形状の凹部であり、拡散ドット52の各辺の長さが約0.6mm、深さが約0.4mmであり、隣り合う四角錐型の拡散ドット52間のピッチが2.0mmに形成されているものとしたが、これに限定されるものではなく、適宜好適なサイズを選択することができる。四角錐型の拡散ドット52の各辺の長さは、例えば、0.2mm〜1.5mmで選択してもよい。また、四角錐型の拡散ドット52の深さは、例えば、0.4mm〜0.8mmで選択してもよい。更に、隣り合う四角錐型の拡散ドット52間のピッチは、例えば、1.5mm〜8.0mmのピッチの間から適宜選択してもよいし、1.5mm〜3.0mmであってもよい。いずれの場合であっても、上述した実施の形態と同様の効果を得ることができる。   In the embodiment described above, the diffusion dot 52 is a quadrangular pyramid-shaped recess, the length of each side of the diffusion dot 52 is about 0.6 mm, the depth is about 0.4 mm, and the adjacent quadrangular pyramid shape. However, the present invention is not limited to this, and a suitable size can be selected as appropriate. The length of each side of the quadrangular pyramid-shaped diffusion dot 52 may be selected from 0.2 mm to 1.5 mm, for example. The depth of the quadrangular pyramid-shaped diffusion dots 52 may be selected from 0.4 mm to 0.8 mm, for example. Furthermore, the pitch between adjacent quadrangular pyramid-shaped diffusion dots 52 may be appropriately selected from a pitch of 1.5 mm to 8.0 mm, or may be 1.5 mm to 3.0 mm. . In any case, the same effect as that of the above-described embodiment can be obtained.

上述した実施の形態では、拡散ドット52は四角錐形状の凹部であるものとしたが、拡散ドット52として形成される拡散凹部の形状及び大きさは、特に限定するものではない。適宜様々な形状及び大きさの拡散凹部からなる拡散ドット52を採用することができる。例えば、図8Bは、円錐側の拡散凹部からなる拡散ドット52を示している。図8Cは、四角柱型の拡散凹部からなる拡散ドット52を示している。図8Dは、四角錐台形の拡散凹部からなる拡散ドット52を示している。図8Eは、半球型の拡散凹部からなる拡散ドット52を示している。また作製方法としては、超音波加工、加熱加工、レーザー加工、切削加工等種々の加工方法を採用してもよいし、予め凹凸が刻まれた金型を用いて射出成形等の方法を用いてもよい。また、例えば、図8Fに示すように、凸状の膨らんだ拡散凸部であってもよい。拡散凸部は、クリーン印刷やシルク印刷等によって、盛り上がるように(凸状)主面に形成する。また、それぞれの拡散ドット52の大きさは、同じであっても異なっていても良い。例えば、後方側から上方側に向かって、四角錐型の拡散ドット52の各辺を徐々に長くしたり、四角錐型の拡散ドット52の深さを徐々に深くしたりしても良い。こうすれば、LED64から近く光が強い位置では拡散される光量が小さくなり、LED64から遠ざかるにつれて拡散される光量が大きくなるため、主面から照射される光の光量を均一に近づけることができる。   In the above-described embodiment, the diffusion dots 52 are quadrangular pyramid-shaped recesses, but the shape and size of the diffusion recesses formed as the diffusion dots 52 are not particularly limited. A diffusion dot 52 composed of diffusion recesses of various shapes and sizes can be used as appropriate. For example, FIG. 8B shows a diffusion dot 52 composed of a diffusion recess on the conical side. FIG. 8C shows a diffusing dot 52 composed of a quadrangular prism-shaped diffusing recess. FIG. 8D shows a diffusion dot 52 composed of a quadrangular pyramid-shaped diffusion recess. FIG. 8E shows a diffusing dot 52 comprising a hemispherical diffusing recess. In addition, as a manufacturing method, various processing methods such as ultrasonic processing, heating processing, laser processing, and cutting processing may be employed, or a method such as injection molding is used using a mold in which irregularities are engraved in advance. Also good. Further, for example, as shown in FIG. The diffusion convex portion is formed on the main surface so as to rise (clean) by clean printing, silk printing, or the like. The size of each diffusion dot 52 may be the same or different. For example, each side of the quadrangular pyramid-shaped diffusion dot 52 may be gradually lengthened from the rear side to the upper side, or the depth of the quadrangular pyramid-shaped diffusion dot 52 may be gradually increased. By doing so, the amount of light diffused becomes small at a position where the light is close to the LED 64 and the light is strong, and the amount of light diffused increases as the distance from the LED 64 increases, so that the amount of light emitted from the main surface can be made closer to uniform.

上述した実施の形態では、LED64は、平面発光型の白色の発光ダイオードとしたが、平面発光型に限定されるものでなく、側面発光型、砲弾型等いずれのタイプであってもよい。また、LED64の光の色は、白色に限定するものではなく、例えば、赤色、橙色、黄色、緑色、青色、藍色又は紫色のいずれかの色若しくはそれらの色の組み合わせ等であってもよい。いずれの場合であっても、上述した実施の形態と同様の効果が得られる。   In the embodiment described above, the LED 64 is a planar light emitting white light emitting diode, but is not limited to the planar light emitting diode, and may be any type such as a side light emitting type or a shell type. Further, the color of light of the LED 64 is not limited to white, and may be, for example, any one of red, orange, yellow, green, blue, indigo and purple, or a combination of these colors. . In any case, the same effect as the above-described embodiment can be obtained.

上述した実施の形態では、吊り下げ部材40に上方に凹みを有する直線形状の挿入凹部42と、上方側が開放されたL字形状に形成された固定凹部44とを設けるものとしたが、吊り下げ部材40を取り付け部材30の前方側及び後方側に設けられた突出部36a及び突出部36bに吊り下げ可能な形状であれば、これらの形状に限定されるものではなく、また、挿入凹部42と固定凹部44とが同一の形状であっても、異なる形状であっても良い。いずれの場合であっても、吊り下げ部材40を取り付け部材30に吊り下げることができる。   In the above-described embodiment, the suspension member 40 is provided with the linear insertion recess 42 having a dent on the upper side and the fixed recess 44 formed in an L shape with the upper side open. The member 40 is not limited to these shapes as long as the member 40 can be suspended from the protrusions 36a and 36b provided on the front side and the rear side of the attachment member 30, and the insertion recess 42 and The fixed recess 44 may have the same shape or a different shape. In either case, the suspension member 40 can be suspended from the attachment member 30.

上述した実施の形態では、雄ねじ84を設けるにあたり、雄ねじ84の頭の厚みと保護部材80の前方側及び後方側の内面80bと縦板82bとの間隔が略同一となる位置に固定部材81を固定することで雄ねじ84の脱落を防止するものとしたが、雄ねじ84を貫通孔82cに螺合することで雄ねじ84の脱落を防止するものとしても良いし、前方側及び後方側の内面80bと縦板82bとの間隔を雄ねじ84の軸の長さより短くすることで、雄ねじ84の脱落する可能性を未然に低減してもよい。いずれの場合であっても、上述した実施の形態と同様の効果が得られる。   In the above-described embodiment, when the male screw 84 is provided, the fixing member 81 is placed at a position where the thickness of the head of the male screw 84 and the distance between the front side and rear side inner surface 80b of the protective member 80 and the vertical plate 82b are substantially the same. Although the male screw 84 is prevented from falling off by being fixed, the male screw 84 may be prevented from falling off by screwing the male screw 84 into the through hole 82c, and the front and rear inner surfaces 80b The possibility that the male screw 84 will drop off may be reduced by making the distance from the vertical plate 82b shorter than the length of the shaft of the male screw 84. In any case, the same effect as the above-described embodiment can be obtained.
