本実施形態の表示装置１は、図３に示すように、板状に形成されたパネル２と、パネル２を保持する本体３とを備えている。本実施形態では、一例として、表示装置１が誘導灯として用いられる場合について説明するが、表示装置１は、誘導灯に限らず、例えば自照式看板などであってもよい。   As shown in FIG. 3, the display device 1 of this embodiment includes a panel 2 formed in a plate shape and a main body 3 that holds the panel 2. In the present embodiment, a case where the display device 1 is used as a guide light will be described as an example. However, the display device 1 is not limited to a guide light, and may be, for example, a self-illuminating signboard.

パネル２は、図１に示すように、矩形板状の表示部２１と、表示部２１へ給電するために表示部２１の外周縁部の一辺（図１の上辺）から突出して設けられた給電部２２とを備えている。   As shown in FIG. 1, the panel 2 has a rectangular plate-like display unit 21 and a power supply provided so as to protrude from one side of the outer peripheral edge of the display unit 21 (the upper side in FIG. 1) in order to supply power to the display unit 21. Part 22.

表示部２１は、図示しないが、光源と表示部側基材とを備えている。光源は、例えば有機ＥＬ（ElectroLuminescence）などのエレクトロルミネッセンスであり、複数の層から形成されており、本体３の制御ブロック（図示せず）から給電されると平面発光する。表示部側基材には、光源の発光部を形成する複数の層が設けられており、光源を通電させて発光させるように配線されている。表示部２１は、例えば避難口へ誘導するためのピクトグラムを表示する。ただし、表示部２１の表示内容は、上記ピクトグラムに限らず、建物の出入口の表示や案内表示などであってもよい。   Although not shown, the display unit 21 includes a light source and a display unit side base material. The light source is, for example, electroluminescence such as organic EL (ElectroLuminescence), and is formed of a plurality of layers, and emits planar light when fed from a control block (not shown) of the main body 3. The base material on the display unit side is provided with a plurality of layers that form the light emitting part of the light source, and is wired so as to emit light when the light source is energized. The display unit 21 displays, for example, a pictogram for guiding to an evacuation exit. However, the display content of the display unit 21 is not limited to the pictogram, but may be a display of an entrance / exit of a building or a guidance display.

給電部２２は、本体３に接続される給電接続部２２２と、給電接続部２２２が実装された給電部側基材２２１とを備えており、表示部２１の外周縁部に取り付けられている。給電部２２は、例えば表示部２１の表示部側基材（図示せず）に接合されることによって、表示部側基材に設けられている。   The power supply unit 22 includes a power supply connection unit 222 connected to the main body 3 and a power supply unit side substrate 221 on which the power supply connection unit 222 is mounted, and is attached to the outer peripheral edge of the display unit 21. The power feeding unit 22 is provided on the display unit side base material, for example, by being joined to a display unit side base material (not shown) of the display unit 21.

給電接続部２２２は、複数（図示例では４つ）の導電端子２２３，２２３，……で構成されており、外部電源（図示せず）からパネル２の光源（図示せず）へ給電されるように、本体３の外部電源供給部３２（図２参照）を介して上記外部電源と電気的に接続する。   The power supply connecting portion 222 is composed of a plurality (four in the illustrated example) of conductive terminals 223, 223,..., And supplies power from an external power source (not shown) to the light source (not shown) of the panel 2. As described above, the external power source 32 is electrically connected to the external power source 32 (see FIG. 2).

給電部側基材２２１は、例えば柔軟性のあるフレキシブル基材や、柔軟性のある部分と硬質の部分とからなる基材などであり、少なくとも表示部２１との接合箇所が柔軟性を有して変形可能である。この給電部側基材２２１が折り曲げられることによって、給電部側基材２２１に実装された給電接続部２２２は、表示部２１に対して向きが可変自在となる。給電部側基材２２１が折り曲げられない状態では、給電接続部２２２の向きは表示部２１の上下方向となるが、給電部側基材２２１が例えば９０°折り曲げられた状態では、給電接続部２２２の向きは表示部２１の前後方向となる。   The power feeding unit side base material 221 is, for example, a flexible flexible base material or a base material composed of a flexible part and a hard part, and at least a joint portion with the display unit 21 has flexibility. And can be deformed. By bending the power supply unit base 221, the direction of the power supply connection unit 222 mounted on the power supply unit base 221 can be changed with respect to the display unit 21. In a state in which the power supply unit base 221 is not bent, the direction of the power supply connection unit 222 is the vertical direction of the display unit 21, but in a state in which the power supply unit base 221 is bent by 90 °, for example, Is the front-rear direction of the display unit 21.

The main body 3 further includes a control block and a storage battery as an external power source, although not shown. The control block and the storage battery are housed in the housing 31. When the commercial power source is energized, the control block converts the power from the commercial power source and supplies it to the light source in order to turn on the light source (not shown) of the panel 2. On the other hand, when the commercial power supply fails, the light source of the panel 2 is lit by being fed from the storage battery.

筐体３１は、例えば合成樹脂の成型品や金属製の筐体であり、例えば天井４１や壁４２（図７参照）などの造営面に取り付けられる。図２に示すように、筐体３１は、下面および側面にノックアウト部３１１が設けられている。施工者は、筐体３１に外部電源供給部３２を取り付ける際に、ノックアウト部３１１を必要に応じて打ち抜いて筐体３１に開口を形成し、この開口の位置に外部電源供給部３２を取り付ける。これにより、筐体３１に不要な開口が形成されるのを防ぐことができる。   The housing 31 is, for example, a synthetic resin molded product or a metal housing, and is attached to a construction surface such as a ceiling 41 or a wall 42 (see FIG. 7). As shown in FIG. 2, the casing 31 is provided with knockout portions 311 on the lower surface and side surfaces. When the installer attaches the external power supply unit 32 to the housing 31, the knockout unit 311 is punched as necessary to form an opening in the housing 31, and the external power supply unit 32 is attached to the position of this opening. Thereby, it is possible to prevent unnecessary openings from being formed in the housing 31.

外部電源供給部３２は、パネル２の給電接続部２２２（図１参照）と外部電源（図示せず）とが電気的に接続されるように給電接続部２２２が接続される部品である。この外部電源供給部３２は、パネル２の給電部２２が接続される接続部３２１を備えており、この接続部３２１の差込口が外部に露出するように筐体３１に設けられている。本実施形態では、外部電源供給部３２は、ねじ止めによって筐体３１に固定されている。接続部３２１は、例えば導電材料によって弾性（ばね性）を有するように形成された端子であり、給電部２２が差込口から差し込まれた際に給電部２２を弾性によって挟持して保持する。   The external power supply unit 32 is a component to which the power supply connection part 222 is connected so that the power supply connection part 222 (see FIG. 1) of the panel 2 and the external power supply (not shown) are electrically connected. The external power supply unit 32 includes a connection unit 321 to which the power supply unit 22 of the panel 2 is connected. The external power supply unit 32 is provided in the housing 31 so that the insertion port of the connection unit 321 is exposed to the outside.
