Description

画像表示装置Image display device
　本発明は、画像表示パネルを具えた画像表示装置に関する。 The present invention relates to an image display apparatus provided with an image display panel.
　この種の画像表示装置は、画像表示パネルを収容する筐体を具えており、該筐体の背面を室内の壁に向けて床に設置され、或いは、室内の壁に取り付けて使用される（例えば特開２００５－２８６９８７号公報参照）。画像表示装置を床に設置する場合、筐体にスタンドを設けて画像表示装置を床に自立させることになる。従って、画像表示装置のメンテナンス作業や修理作業を行う際にも、画像表示装置を自立させたままの状態で作業を行うことが出来、これらの作業に要する時間や労力は少なくて済む。 This type of image display device includes a housing for housing an image display panel, and the back of the housing faces the wall of the room and is installed on the floor or attached to the wall of the room (used ( See, for example, JP-A-2005-286987). When the image display device is installed on the floor, a stand is provided on the housing to make the image display device stand on the floor. Therefore, even when performing maintenance work or repair work of the image display apparatus, the work can be performed in a state where the image display apparatus is made to stand on its own, and the time and labor required for these work can be reduced.
　これに対し、画像表示装置を壁に取り付けて使用する場合、筐体にはスタンドが設けられない。このため、画像表示装置を壁から取り外してメンテナンス作業や修理作業を行う場合には、画像表示装置を自立させることが出来ず、画像表示装置を横倒しにしなければならなかった。従って、画像表示装置の前面側及び背面側の両方からメンテナンス作業等を行う場合には、画像表示装置を裏返す作業が必要となっていた。 On the other hand, when the image display apparatus is attached to a wall and used, the case is not provided with a stand. For this reason, when the image display apparatus is removed from the wall and maintenance work or repair work is performed, the image display apparatus can not stand on its own, and the image display apparatus has to be turned over. Therefore, when performing maintenance work or the like from both the front side and the back side of the image display device, it is necessary to turn the image display device over.
　画像表示装置を一時的に自立させることを可能にするべく、筐体の形状として、該筐体の高さ方向に対して底面が垂直に拡がった形状を採用することが考えられる。しかし、従来から、筐体の形状として、筐体の高さ方向に筐体の背面壁の下端縁が筐体の前面壁の下端縁からずれた形状が多く採用されており、この従来の形状を変更しなければならなくなる。 In order to allow the image display device to temporarily stand on its own, it is conceivable to adopt a shape in which the bottom surface vertically extends in the height direction of the housing as the shape of the housing. However, conventionally, as the shape of the housing, a shape in which the lower end edge of the back wall of the housing deviates from the lower end edge of the front wall of the housing in the height direction of the housing is adopted. You will have to change it.
　本発明に係る画像表示装置は、画像表示パネルと、該画像表示パネルを収容する筐体とを具え、該筐体の前面壁には、画像表示パネルの画面を外部から視認可能にする画像表示窓が設けられ、前記筐体は、その高さ方向に該筐体の背面壁の下端縁が該筐体の前面壁の下端縁からずれた形状を有している。ここで、前記筐体の底面には、少なくとも該筐体の背面壁の下端縁又はその近傍位置に、左右一対の突起部が形成されており、各突起部は、前記筐体の前面壁の下端縁と対向する位置又はその近傍位置まで突出している。 An image display apparatus according to the present invention comprises an image display panel and a case for housing the image display panel, and an image display for making the screen of the image display panel visible from the outside on the front wall of the case A window is provided, and the housing has a shape in which the lower edge of the rear wall of the housing is offset from the lower edge of the front wall of the housing in the height direction. Here, on the bottom surface of the casing, a pair of left and right protrusions are formed at least at the lower end edge of the rear wall of the casing or in the vicinity thereof, and each protrusion is the front wall of the casing It projects to a position opposite to the lower end edge or a position near the position.

　筐体(２)の上面壁、下面壁、左側面壁、及び右側面壁は、画像表示装置の前面領域が背面領域より大きな面積を有する様に傾斜している。このため、図３に示す様に筐体(２)は、その高さ方向(91)に該筐体(２)の背面壁(22)の下端縁(22a)が該筐体(２)の前面壁(21)の下端縁(21a)からずれた形状を有している。 The upper surface wall, the lower surface wall, the left side wall, and the right side wall of the housing (2) are inclined such that the front area of the image display device has a larger area than the rear area. For this reason, as shown in FIG. 3, the lower end edge (22a) of the back wall (22) of the case (2) is the same as that of the case (2) in the height direction (91) of the case (2). It has a shape offset from the lower end edge (21a) of the front wall (21).
　ここで図４に示す様に、筐体(２)の底面には、該筐体(２)の背面壁(22)の下端縁(22a)から前方に向けて延びる左右一対の突起部(３)(３)が形成されており、各突起部(３)は、図３に示す様に、筐体(２)の前面壁(21)の下端縁(21a)と対向する位置又はその近傍位置まで突出している。 Here, as shown in FIG. 4, the bottom surface of the housing (2) is provided with a pair of left and right protrusions (3) extending forward from the lower end edge (22a) of the back wall (22) of the housing (2). (3) is formed, and each projection (3) is, as shown in FIG. 3, a position facing or near the lower edge (21a) of the front wall (21) of the housing (2) Stands out.
　図５に示す様に、筐体(２)には更に、リモートコントローラ（図示せず）からの制御信号を受信するための受信センサ(41)、及び、筐体(２)の周囲の環境に応じて変化する情報を取得する情報取得センサ(42)が取り付けられている。ここで、情報取得センサ(42)には、筐体(２)又は液晶表示パネル(１)に入射する光量に応じて変化する光量情報を取得するセンサ、又は、筐体(２)の周囲の温度に応じて変化する温度情報を取得するセンサ等、様々なセンサが含まれる。 As shown in FIG. 5, the housing (2) further includes a reception sensor (41) for receiving a control signal from a remote controller (not shown), and an environment around the housing (2). An information acquisition sensor (42) is attached to acquire information that changes accordingly. Here, in the information acquisition sensor (42), a sensor that acquires light amount information that changes in accordance with the amount of light incident on the housing (2) or the liquid crystal display panel (1), or around the housing (2) Various sensors are included, such as sensors that acquire temperature information that changes according to temperature.
　具体的には、筐体(２)を構成する第２筐体構成部材(2b)の内面に、図６に示す様に受信センサ(41)及び情報取得センサ(42)の何れのセンサをも取り付けることが可能な取付け台(４)が、図５に示す様に上下２箇所に設けられている。そして、上下２箇所に設けられている取付け台(４)(４)から選択された上側の取付け台(４)に情報取得センサ(42)が取り付けされ、上下２箇所に設けられている取付け台(４)(４)から選択された下側の取付け台(４)に受信センサ(41)が取り付けられている。尚、図示していないが、各取付け台(４)へのセンサの取付けには、一対のネジ部材が用いられる。
　斯くして、これらの取付け台(４)(４)には、受信センサ(41)及び情報取得センサ(42)が、これらの取付け位置を交換することが可能に取り付けられている。 Specifically, as shown in FIG. 6, both the reception sensor (41) and the information acquisition sensor (42) are provided on the inner surface of the second housing component (2b) constituting the housing (2). Attachable mounts (4) are provided at upper and lower two places as shown in FIG. Then, the information acquisition sensor (42) is attached to the upper mount (4) selected from the mounts (4) and (4) provided at the upper and lower two places, and the mounts provided at the upper and lower two places (4) The reception sensor (41) is attached to the lower mount (4) selected from (4). Although not shown, a pair of screw members are used to attach the sensor to each mount (4).
Thus, the reception sensor (41) and the information acquisition sensor (42) are attached to these mounts (4) (4) in such a manner that their mounting positions can be exchanged.
　一方、第２筐体構成部材(2b)には、図６及び図７に示す様に、各取付け台(４)の近傍位置に、第２筐体構成部材(2b)を内面から外面に貫通する３つのセンサ用貫通孔(23)～(23)が設けられており、取付け台(４)に取り付けられたセンサは３つのセンサ用貫通孔(23)～(23)に向けて配置されることになる。これにより、各センサは、３つのセンサ用貫通孔(23)～(23)を通じてセンシングを行うことが可能となっている。 On the other hand, as shown in FIGS. 6 and 7, the second housing component (2b) penetrates the second housing component (2b) from the inner surface to the outer surface, as shown in FIGS. 6 and 7. Three sensor through holes (23) to (23) are provided, and the sensors attached to the mount (4) are arranged to face the three sensor through holes (23) to (23) It will be. Thus, each sensor can perform sensing through the three sensor through holes (23) to (23).
　又、図７に示す様に、第２筐体構成部材(2b)の外面には、３つのセンサ用貫通孔(23)～(23)を塞ぐシール部材(40)が貼着されている。よって、３つのセンサ用貫通孔(23)～(23)からは水や塵が浸入し難く、その結果、取付け台(４)に取り付けられたセンサは水や塵から保護されることになる。 Further, as shown in FIG. 7, on the outer surface of the second housing component (2b), a seal member (40) for sealing the three sensor through holes (23) to (23) is attached. Therefore, water and dust do not easily enter from the three sensor through holes (23) to (23). As a result, the sensor attached to the mount (4) is protected from water and dust.
　第１筐体構成部材(2a)及び第２筐体構成部材(2b)は、ＡＢＳ（Acrylonitrile　Butadiene　Styrene）樹脂やＰＣ（Polycarbonate）樹脂等、高い難燃性を有する樹脂から形成されている。 The first housing component (2a) and the second housing component (2b) are formed of a resin having high flame retardancy, such as ABS (Acrylonitrile Butadiene Styrene) resin or PC (Polycarbonate) resin.
　一方、図示していないが、第１筐体構成部材(2a)の外面には、該第１筐体構成部材(2a)が有する耐候性と耐汚染性よりも高い耐候性と耐汚染性を有する被膜が形成されている。ここで、該被膜は、耐候性と耐汚染性とを有する塗料を第１筐体構成部材(2a)の外面に塗布することにより形成されたものである。尚、耐候性は、紫外線に対する耐性を意味し、耐汚染性は、有機溶剤に対する耐性を意味する。又、該塗料には、カシュー社製のストロンエースやアスコート等を用いることが出来る。
　同様に、第２筐体構成部材(2b)の外面には、該第２筐体構成部材(2b)が有する耐候性と耐汚染性よりも高い耐候性と耐汚染性を有する被膜が形成されている。 On the other hand, although not shown, on the outer surface of the first housing component (2a), the weather resistance and the contamination resistance higher than that of the first housing component (2a) are obtained. The film which it has is formed. Here, the film is formed by applying a paint having weatherability and stain resistance to the outer surface of the first housing component (2a). Incidentally, the weather resistance means the resistance to ultraviolet light, and the stain resistance means the resistance to an organic solvent. In addition, Stron Ace or As Coat manufactured by Cashew may be used as the paint.
Similarly, on the outer surface of the second housing component (2b), a film having weather resistance and contamination resistance higher than that of the second housing component (2b) is formed. ing.
　本実施形態の画像表示装置は、室内又は屋外に設けられている壁や柱等に設置することが可能である。具体的には、画像表示装置は、壁や柱等の一定の位置に取り付けられた固定具（図示せず）に固定されることにより、壁や柱等に設置されることになる。より具体的な構成は、以下のとおりである。 The image display apparatus of the present embodiment can be installed on a wall, a pillar, or the like provided indoors or outdoors. Specifically, the image display apparatus is installed on a wall, a pillar, or the like by being fixed to a fixture (not shown) attached to a fixed position such as a wall, a pillar, or the like. A more specific configuration is as follows.
　図２に示す様に、筐体(２)内には、固定具に連結されるべき左右一対の連結部材(５)(５)が上下に一対ずつ配備されている。図８及び図１２に示す様に、各連結部材(５)は、筐体(２)の背面壁(22)と液晶表示パネル(１)の背部との間に介在しており、連結部材(５)には、該連結部材(５)をクランク状に屈曲させることにより、液晶表示パネル(１)の背面(11)に沿う第１平坦部(51)と、筐体(２)の背面壁(22)に沿う第２平坦部(52)とが形成されている。又、第１平坦部(51)と第２平坦部(52)とは、両平坦部(51)(52)に対して略垂直に拡がる第３平坦部(53)によって互いに結合されている。 As shown in FIG. 2, in the housing (2), a pair of left and right connecting members (5) and (5) to be connected to the fixing tool are provided in pairs at the top and bottom. As shown in FIG. 8 and FIG. 12, each connecting member (5) is interposed between the back wall (22) of the housing (2) and the back of the liquid crystal display panel (1). In 5), by bending the connecting member (5) in a crank shape, the first flat portion (51) along the back surface (11) of the liquid crystal display panel (1), and the back wall of the housing (2) A second flat portion (52) is formed along the (22). Also, the first flat portion (51) and the second flat portion (52) are connected to each other by a third flat portion (53) which extends substantially perpendicularly to the two flat portions (51) (52).
　図９及び図１０に示す様に、第１平坦部(51)と第３平坦部(53)には、両平坦部(51)(53)に対して略垂直に拡がる一対の第１補強部(54)(54)が結合されると共に、第２平坦部(52)と第３平坦部(53)には、両平坦部(52)(53)に対して略垂直に拡がる一対の第２補強部(55)(55)が結合されている。これにより、連結部材(５)の強度が高められている。 As shown in FIGS. 9 and 10, in the first flat portion (51) and the third flat portion (53), a pair of first reinforcing portions extending substantially perpendicularly to both flat portions (51) (53) (54) and (54) are coupled, and the second flat portion (52) and the third flat portion (53) are a pair of second flat portions that extend substantially perpendicularly to both flat portions (52) and (53). Reinforcement parts (55) (55) are connected. Thereby, the strength of the connecting member (5) is enhanced.
　図８及び図１２に示す様に、各連結部材(５)の第１平坦部(51)には、該第１平坦部(51)の一部を屈曲させることによって***部(６)が形成されており、該***部(６)は、筐体(２)の背面壁(22)側へ***している。***部(６)には、液晶表示パネル(１)を筐体(２)に固定するためのネジ部材(７)が貫通すべき貫通孔(61)が開設されると共に、液晶表示パネル(１)側の表面に、貫通孔(61)を包囲する円筒部(62)（図９及び図１０も参照）が突設されている。 As shown in FIGS. 8 and 12, the first flat portion (51) of each connecting member (5) is formed with a raised portion (6) by bending a part of the first flat portion (51). The raised portion (6) is raised toward the back wall (22) of the housing (2). A through hole (61) through which a screw member (7) for fixing the liquid crystal display panel (1) to the housing (2) is to be penetrated is formed in the raised portion (6) and the liquid crystal display panel (1) A cylindrical portion (62) (see also FIG. 9 and FIG. 10) surrounding the through hole (61) is protruded from the surface on the) side.
　ここで、円筒部(62)は、図１２に示す様に***部(６)の高さ寸法Ｔ１と略同一の高さ寸法Ｔ２を有すると共に、図１３に示す様にネジ部材(７)が貫挿されたときに該ネジ部材(７)と円筒部(62)の内周面との間に僅かな隙間が形成されることとなる内面形状を有している。 Here, the cylindrical portion (62) has a height dimension T2 substantially the same as the height dimension T1 of the raised portion (6) as shown in FIG. 12, and as shown in FIG. 13, the screw member (7) It has an inner surface shape in which a slight gap is formed between the screw member (7) and the inner peripheral surface of the cylindrical portion (62) when it is inserted.
　図８及び図１２に示す様に、連結部材(５)の第２平坦部(52)には、連結部材(５)を固定具に連結するためのボルト（図示せず）が捻じ込まれるべき雌ネジ部(８)が、筐体(２)の背面壁(22)側に向けて突設されている。 As shown in FIGS. 8 and 12, a bolt (not shown) for connecting the connecting member (5) to the fixture should be screwed into the second flat portion (52) of the connecting member (5). The female screw portion (8) is protruded toward the back wall (22) side of the housing (2).
　一方、筐体(２)の背面壁(22)には、各連結部材(５)に対応して、画像表示装置の組立て状態において連結部材(５)の第１平坦部(51)と対向することとなる領域に、筐体(２)の内側に***した***部(81)が形成されると共に、画像表示装置の組立て状態において連結部材(５)の第２平坦部(52)と対向することとなる領域に、雌ネジ部(８)が貫挿されるべき貫通孔(80)が設けられている。ここで、***部(81)の先端部には、ネジ部材(７)が貫通すべき貫通孔(82)が開設されている。 On the other hand, the rear wall (22) of the housing (2) faces the first flat portion (51) of the connecting member (5) in the assembled state of the image display device corresponding to each connecting member (5). In the region to be formed, a raised ridge (81) is formed on the inside of the housing (2), and it faces the second flat portion (52) of the connecting member (5) in the assembled state of the image display device In the area to be provided, a through hole (80) into which the female screw (8) is to be inserted is provided. Here, a through hole (82) to be penetrated by the screw member (7) is opened at the tip of the raised portion (81).
　図１３に示す様に、画像表示装置の組立て状態においては、連結部材(５)の第１平坦部(51)が液晶表示パネル(１)の背面(11)に当接し、連結部材(５)の第２平坦部(52)に突設されている雌ネジ部(８)が、貫通孔(80)に貫挿されて筐体(２)の背面に露出する。
　又、連結部材(５)の第１平坦部(51)に形成されている***部(６)には、その背面側から、筐体(２)の背面壁(22)に形成されている***部(81)が当接する。このとき、第１平坦部(51)の***部(６)に設けられている貫通孔(61)と、筐体(２)の***部(81)に設けられている貫通孔(82)とが対向する。 As shown in FIG. 13, in the assembled state of the image display device, the first flat portion (51) of the connecting member (5) abuts on the back surface (11) of the liquid crystal display panel (1), and the connecting member (5) The female screw portion (8) provided to project from the second flat portion (52) is inserted through the through hole (80) and exposed on the back surface of the housing (2).
In addition, the protuberances (6) formed on the first flat portion (51) of the connection member (5) are protuberances formed on the back wall (22) of the housing (2) from the back side. The part (81) abuts. At this time, the through hole (61) provided in the raised portion (6) of the first flat portion (51) and the through hole (82) provided in the raised portion (81) of the housing (2) Face each other.
　そして、液晶表示パネル(１)の背部にはネジ孔(12)（図８及び図１２参照）が設けられており、ネジ部材(７)が、両***部(６)(81)に設けられている貫通孔(61)(82)を貫通してネジ孔(12)に捻じ込まれる。このとき、該貫通孔(61)(82)に貫挿されたネジ部材(７)は、円筒部(62)を通過することになるので、該ネジ部材(７)が捻じ込まれるべきネジ孔(12)へスムーズに導かれることになる。これにより、液晶表示パネル(１)は、筐体(２)内に固定されると共に、連結部材(５)に直接連結されることになる。 Then, a screw hole (12) (see FIGS. 8 and 12) is provided on the back of the liquid crystal display panel (1), and a screw member (7) is provided on both of the raised portions (6) and (81). Through the through holes (61) (82) and screwed into the screw holes (12). At this time, since the screw member (7) inserted through the through holes (61) (82) passes through the cylindrical portion (62), the screw hole to which the screw member (7) should be screwed It will be led to (12) smoothly. Thus, the liquid crystal display panel (1) is fixed in the housing (2) and directly connected to the connection member (5).
　ここで、上記画像表示装置においては、液晶表示パネル(１)の背面(11)に連結部材(５)の第１平坦部(51)が当接し、更に該第１平坦部(51)（具体的には***部(６)）の背面に筐体(２)の***部(81)が当接しているので、液晶表示パネル(１)の背部には、液晶表示パネル(１)の背面(11)に近い位置からネジ部材(７)が捻じ込まれることになる。従って、液晶表示パネル(１)と連結部材(５)との締結強度は高くなっている。 Here, in the image display device, the first flat portion (51) of the connecting member (5) is in contact with the back surface (11) of the liquid crystal display panel (1), and the first flat portion (51) (specifically Since the ridge (81) of the housing (2) is in contact with the back of the ridge (6), the back of the liquid crystal display panel (1) The screw member (7) is screwed in from a position close to 11). Therefore, the fastening strength between the liquid crystal display panel (1) and the connecting member (5) is high.
　上記画像表示装置を固定具に固定する場合、ボルトが固定具を貫通した状態（図示せず）で雌ネジ部(８)に捻じ込まれることになる。これにより、連結部材(５)が固定具に連結されることになる。ここで、雌ネジ部(８)は、貫通孔(80)に貫挿されて筐体(２)の背面に露出している。従って、画像表示装置を固定具に固定する際に、雌ネジ部(８)は固定具に近づくことになる。このため、固定具に近い位置にて雌ネジ部(８)にボルトが捻じ込まれることになる。よって、ボルトによって連結された連結部材(５)と固定具との締結強度は高くなる。 When the image display device is fixed to the fixture, the bolt is screwed into the female screw (8) in a state (not shown) through the fixture. Thereby, the connecting member (5) is connected to the fixture. Here, the female screw portion (8) is inserted into the through hole (80) and exposed on the back surface of the housing (2). Therefore, when fixing the image display device to the fixture, the female screw (8) approaches the fixture. Therefore, a bolt is screwed into the female screw portion (8) at a position close to the fixing tool. Therefore, the fastening strength between the connecting member (5) connected by the bolt and the fixture becomes high.
　この様に上記画像表示装置を固定具に固定することにより、液晶表示パネル(１)は、連結部材(５)を介して固定具に連結されることになる。このため、筐体(２)が経年劣化してその強度が低下した場合でも、液晶表示パネル(１)は固定具から脱落することがない。 By fixing the image display device to the fixture in this manner, the liquid crystal display panel (1) is connected to the fixture via the connecting member (5). For this reason, even when the housing (2) is aged and its strength is reduced, the liquid crystal display panel (1) does not fall off from the fixture.
　又、上記画像表示装置においては、液晶表示パネル(１)は、ボルトとは別のネジ部材(７)によって連結部材(５)に連結されている。従って、筐体(２)の背面側からネジ部材(７)を取り外すことにより、固定具への連結部材(５)の連結を解除することなく、液晶表示パネル(１)の筐体(２)への固定を解除することが出来る。よって、筐体(２)の第１筐体構成部材(2a)を第２筐体構成部材(2ｂ)から取り外した後、ネジ部材(７)を取り外すことにより、固定具への連結部材(５)の連結を解除せずに液晶表示パネル(１)を筐体(２)から取り外すことが可能である。 In the image display device, the liquid crystal display panel (1) is connected to the connecting member (5) by a screw member (7) other than a bolt. Therefore, the housing (2) of the liquid crystal display panel (1) can be obtained without releasing the connection of the connecting member (5) to the fixing tool by removing the screw member (7) from the back side of the housing (2). You can unlock it. Therefore, by removing the screw member (7) after removing the first case component member (2a) of the case (2) from the second case component member (2b), the connecting member (5 It is possible to remove the liquid crystal display panel (1) from the housing (2) without releasing the connection of.
　更に、上記画像表示装置においては、連結部材(５)の第１平坦部(51)に形成されている***部(６)は、筐体(２)の背面壁(22)と液晶表示パネル(１)の背部との間に介在するスペーサとして機能する。即ち、第１平坦部(51)の***部(６)の高さ寸法Ｔ１（スペーサの厚さ寸法）を調整することにより、液晶表示パネル(１)の前後方向の位置を調整することが出来る。尚、第１平坦部(51)の***部(６)の高さ寸法Ｔ１を調整することにより、前後方向についての第１平坦部(51)と第２平坦部(52)との間の距離、即ち第３平坦部(53)の長さＬ１（図１２参照）が変化することになる。 Furthermore, in the image display device, the raised portion (6) formed on the first flat portion (51) of the connection member (5) is the back wall (22) of the housing (2) and the liquid crystal display panel It functions as a spacer interposed between the back of 1). That is, by adjusting the height dimension T1 (the thickness dimension of the spacer) of the raised portion (6) of the first flat portion (51), the position of the liquid crystal display panel (1) in the front-rear direction can be adjusted. . The distance between the first flat portion (51) and the second flat portion (52) in the front-rear direction by adjusting the height dimension T1 of the raised portion (6) of the first flat portion (51) That is, the length L1 (see FIG. 12) of the third flat portion 53 changes.
　従って、筐体(２)に収容する液晶表示パネル(１)の厚さ寸法が異なる場合であっても、該厚さ寸法に応じて第１平坦部(51)の***部(６)の高さ寸法Ｔ１を調整することにより、液晶表示パネル(１)を所定の位置に配置することが出来る。よって、上記画像表示装置によれば、筐体(２)を、厚さ寸法の異なる液晶表示パネル(１)において共通化することが可能である。 Therefore, even if the thickness dimension of the liquid crystal display panel (1) housed in the housing (2) is different, the height of the raised portion (6) of the first flat portion (51) according to the thickness dimension By adjusting the dimension T1, the liquid crystal display panel (1) can be disposed at a predetermined position. Therefore, according to the image display device, it is possible to make the housing (2) common to the liquid crystal display panels (1) having different thickness dimensions.
　上述した様に、上記画像表示装置においては、筐体(２)の底面に形成されている各突起部(３)が、筐体(２)の背面壁(22)の下端縁(22a)から前方に向けて延びると共に、筐体(２)の前面壁(21)の下端縁(21a)と対向する位置又はその近傍位置まで突出している。このため、筐体(２)の前面壁(21)の下端縁(21a)と各突起部(３)の先端とが、Ｔ字状に配置されると共に、筐体(２)の高さ方向(91)に対して略垂直な同一平面上に揃うことになる。 As described above, in the image display device, each protrusion (3) formed on the bottom surface of the housing (2) is from the lower end edge (22a) of the back wall (22) of the housing (2) It extends forward and protrudes to a position facing or near the lower end edge (21a) of the front wall (21) of the housing (2). Therefore, the lower end edge (21a) of the front wall (21) of the housing (2) and the tips of the protrusions (3) are arranged in a T shape, and the height direction of the housing (2) It aligns on the same plane substantially perpendicular to (91).
　従って、画像表示装置を水平面上に立てたとき、画像表示装置は、筐体(２)の前面壁(21)の下端縁(21a)と一対の突起部(３)(３)とによって水平面上に支持されることになる。よって、画像表示装置を僅かな力で支えるだけで、画像表示装置を水平面上に立てておくことが可能である。 Therefore, when the image display apparatus is erected on a horizontal plane, the image display apparatus is positioned on the horizontal plane by the lower end edge (21a) of the front wall (21) of the housing (2) and the pair of protrusions (3) (3). Will be supported by Therefore, it is possible to stand the image display device on a horizontal surface only by supporting the image display device with a slight force.
　この様な画像表示装置によれば、画像表示装置を水平面上に立てたままで画像表示装置のメンテナンス作業や修理作業を行うことが可能である。よって、これらの作業に要する時間や労力が削減されることになる。 According to such an image display apparatus, it is possible to perform maintenance work and repair work of the image display apparatus while the image display apparatus is standing on a horizontal surface. Therefore, the time and effort required for these tasks will be reduced.
　又、上記画像表示装置においては、第２筐体構成部材(2b)の内面の２箇所に設けられている取付け台(４)(４)にはそれぞれ、受信センサ(41)及び情報取得センサ(42)が、これらの取付け位置を交換することが可能に取り付けられている。従って、画像表示装置の設置場所や使用態様等に応じて、受信センサ(41)及び情報取得センサ(42)の取付け位置を変更することが出来る。例えば、上側の取付け台(４)に受信センサ(41)を取り付け、下側の取付け台(４)に情報取得センサ(42)を取り付けることや、上下両方の取付け台(４)(４)に受信センサ(41)或いは情報取得センサ(42)を取り付けることが可能である。 Further, in the image display device described above, the mounting sensors (4) and (4) provided at two places on the inner surface of the second housing component (2b) respectively receive a reception sensor (41) and an information acquisition sensor 42) are mounted so as to be able to exchange these mounting positions. Therefore, the mounting positions of the reception sensor (41) and the information acquisition sensor (42) can be changed in accordance with the installation place and use mode of the image display apparatus. For example, attach the reception sensor (41) to the upper mount (4) and attach the information acquisition sensor (42) to the lower mount (4), or to both the upper and lower mounts (4) (4) It is possible to attach a reception sensor (41) or an information acquisition sensor (42).
　更に、上記画像表示装置においては、高い難燃性を有する樹脂から形成された第１筐体構成部材(2a)と第２筐体構成部材(2b)とから筐体(２)が構成されている。ここで、高い難燃性を有する樹脂は着火又は延焼が生じ難い。従って、筐体(２)には、着火又は延焼が生じ難い。 Furthermore, in the above-mentioned image display device, the housing (2) is formed of the first housing component (2a) and the second housing component (2b) which are formed of resin having high flame retardancy. There is. Here, the resin having high flame retardancy hardly causes ignition or fire spread. Therefore, the casing (2) is less likely to be ignited or spread.
　一方、高い難燃性を有する樹脂は、耐候性及び耐汚染性が低下し易い。しかしながら、上記画像表示装置においては、第１筐体構成部材(2a)と第２筐体構成部材(2b)の外面、即ち筐体(２)の外周面が、筐体(２)が有する耐候性と耐汚染性よりも高い耐候性と耐汚染性を有する被膜によって覆われている。 On the other hand, the resin having high flame retardancy tends to have reduced weatherability and stain resistance. However, in the above-mentioned image display device, the outer surfaces of the first housing component (2a) and the second housing component (2b), that is, the outer peripheral surface of the housing (2) have the weather resistance of the housing (2). It is covered by a film that has higher weathering resistance and stain resistance than resistance and stain resistance.
