Description

本発明は、発光表示装置及びこれを適用した電子機器に関するものである。 The present invention relates to a light emitting display device and an electronic apparatus to which the light emitting display device is applied.

従来、腕時計等の電子機器において、例えば文字板や指針等の部品に夜光塗料等の蓄光塗料を印刷その他の手法により部分的に塗布して蓄光部を形成し、これにより明るい所で蓄光部が外部光を受けてエネルギーを蓄え、暗い所で蓄光部が蓄えたエネルギーにより発光するように構成したものがある。 Conventionally, in an electronic device such as a wristwatch, for example, a phosphorescent paint such as a luminescent paint is partially applied to parts such as a dial or a pointer by printing or other methods to form a phosphorescent part. There is a configuration in which energy is stored by receiving external light, and light is emitted by energy stored in the light storage unit in a dark place.

しかし、このような腕時計等の電子機器では、蓄光部を発光させるためには予め外部光に当ててエネルギーを蓄える必要があり、外部光が弱かった場合等には十分な発光輝度を得ることができなかった。
また、このような構成では、予め外部光に当てておくことにより暗い所で蓄光部が発光して時刻等を知ることはできるが、使用者が所望するときに蓄光部を自由に発光させることはできない。
さらに、単に蓄光部が発光するだけであるため、十分な装飾効果を得ることはできないという問題があった。 However, in such an electronic device such as a wristwatch, it is necessary to store energy in advance by applying light to the external light in order to cause the light storage unit to emit light, and when the external light is weak, sufficient light emission luminance can be obtained. could not.
Also, in such a configuration, the phosphorescent part emits light in a dark place by being exposed to external light in advance, so that the time and the like can be known, but the phosphorescent part can emit light freely when desired by the user. I can't.
Furthermore, since the phosphorescent part simply emits light, there is a problem that a sufficient decoration effect cannot be obtained.

そこで、文字板（表示部）と風防部材（カバーガラス）との間に光源部を設けるとともに、風防部材の裏面に高屈折率の被膜を形成し、光源部から照射された光をこの被膜で反射させて文字板上に照射する構成が提案されている（例えば、特許文献１参照）。
このような構成とすれば、文字板等を任意の光で照らすことができ、文字板上の時字等に光に反応する発光層を設けておけば、光源部が点灯した際に発光層を発光させ、時字等を浮かび上がらせることができる。 Therefore, a light source part is provided between the dial (display part) and the windshield member (cover glass), and a film having a high refractive index is formed on the back surface of the windshield member. The structure which reflects and irradiates on a dial plate is proposed (for example, refer patent document 1).
With such a configuration, the dial or the like can be illuminated with arbitrary light, and if a light emitting layer that reacts to light is provided on the time letters on the dial, the light emitting layer is turned on when the light source unit is turned on. Can emit light, and time letters and the like can be raised.

しかしながら、特許文献１に記載の構成では、光源部から照射された光を風防部材の裏面に形成された被膜で反射させて文字板上に照射するため、風防部材と光源部との間に被覆部材を配置することができない。このため、光源部が視認側から見えてしまい、光源部の非点灯時における意匠を損ねてしまう。
また、できるだけ視認側から見た際の外観を損なわないようにするために、光源部の配置の自由度が制限されてしまうという問題もあった。 However, in the configuration described in Patent Document 1, since the light emitted from the light source part is reflected by the coating formed on the back surface of the windshield member and irradiated on the dial, the cover is provided between the windshield member and the light source part. The member cannot be placed. For this reason, a light source part will be visible from the visual recognition side, and the design at the time of non-lighting of a light source part will be spoiled.
Moreover, in order not to impair the appearance when viewed from the viewing side as much as possible, there is also a problem that the degree of freedom of arrangement of the light source unit is limited.

本発明は以上のような事情に鑑みてなされたものであり、視認側から見た際の外観を損なうことなく光源部を配置するとともに、光源部から出力された光により広く発光部を照明することのできる発光表示装置及びこれを適用した電子機器を提供することを目的とするものである。 The present invention has been made in view of the circumstances as described above, and arranges a light source unit without impairing the appearance when viewed from the viewing side, and widely illuminates the light emitting unit with light output from the light source unit. It is an object of the present invention to provide a light-emitting display device that can be used and an electronic apparatus to which the light-emitting display device is applied.

この光源部を視認側から被覆する被覆部材と、
光に反応して有色発光する発光部と、
前記光源部から出力された光が入射すると、この入射した光を前記視認側に反射させる第１の光反射部と、
前記発光部及び前記第１の光反射部よりも前記視認側に配置された半透過性の反射部であり、前記第１の光反射部によって反射された光が入射すると、この入射した光を拡散させて前記視認側とは反対側に拡散反射させ、少なくとも前記発光部に向けて照射する第２の光反射部と、
を備えていることを特徴としている。 In order to solve the above problems, a light-emitting display device according to the present invention includes:
A light source unit that outputs light;
A covering member for covering the light source part from the viewing side;
A light emitting part that emits colored light in response to light;
When the light output from the light source unit is incident, a first light reflecting unit that reflects the incident light to the viewing side;
When the light reflected by the first light reflecting portion is incident on the light transmitting portion and the first light reflecting portion, the semi-transmissive reflecting portion is disposed on the viewing side. A second light reflecting section that diffuses and diffusely reflects to the opposite side of the viewing side and irradiates at least the light emitting section;
It is characterized by having.

また、本発明に係る電子機器は、
請求項１から請求項６のいずれか一項に記載の発光表示装置と、

It is characterized by having.

本発明によれば、光源部を視認側から被覆する被覆部材を設けているため、視認側から見た際の外観を損なうことがなく、光源部の配置が制約されない。
そして、第１の光反射部と第２の光反射部とによって、光源部から出力された光を発光部に導くことができるため、被覆部材によって光源部を視認側から見えないように被覆しても、発光部に広く光を照射することができるという効果を奏する。この結果、例えば、電子機器が腕時計である場合に、時字部上に発光部を形成した場合には、照射された光により時字部を外部から明確に視認することができ、時刻を明確に知ることができる。また、例えば、文字板を配置した場合には、この文字板の上面を発光部からの光により照射して、当該文字板の上面を外部から明確に視認することができる。 According to the present invention, since the covering member that covers the light source unit from the viewing side is provided, the appearance when viewed from the viewing side is not impaired, and the arrangement of the light source unit is not restricted.
Then, since the light output from the light source unit can be guided to the light emitting unit by the first light reflecting unit and the second light reflecting unit, the light source unit is covered by the covering member so as not to be seen from the viewing side. However, there is an effect that the light emitting unit can be widely irradiated with light. As a result, for example, when the electronic device is a wristwatch and the light emitting part is formed on the time character part, the time character part can be clearly seen from the outside by the irradiated light, and the time is clearly indicated. Can know. In addition, for example, when a dial is arranged, the upper surface of the dial can be irradiated with light from the light emitting unit, and the upper surface of the dial can be clearly seen from the outside.

本実施形態に係る腕時計１００は、電気的な駆動により指針１１（時針１１ａ、分針１１ｂ）を回転させて時刻を表示するものである。 FIG. 1 is a front view of the wristwatch according to the present embodiment, FIG. 2 is a cross-sectional view of a main part taken along line II-II in FIG. 1, and FIG. 3 is a main part taken along line III-III in FIG. FIG. 2 and 3, a broken line indicates a path of light output from the ultraviolet light emitting element 9 (see FIG. 2 and the like, which will be described later) serving as a light source unit.
The wristwatch 100 according to the present embodiment displays the time by rotating the hands 11 (hour hand 11a, minute hand 11b) by electrical driving.

この腕時計１００は、中空の短柱形状に形成された本体ケース１を備えている。本実施形態では、本体ケース１は、ほぼ円筒状に形成されている。
この本体ケース１の上下両端部（図１において上下端部）、つまり時計の１２時方向側端部及び６時方向側端部には、時計バンド（図示せず）が取り付けられるバンド取付部２が形成されている。 The wristwatch 100 includes a main body case 1 formed in a hollow short column shape. In the present embodiment, the main body case 1 is formed in a substantially cylindrical shape.
A band attaching portion 2 to which a watch band (not shown) is attached at both upper and lower end portions (upper and lower end portions in FIG. 1) of the main body case 1, that is, an end portion on the 12 o'clock direction and an end portion on the 6 o'clock direction Is formed.

また、本体ケース１の外周部には、時刻合わせの指示、光源部である紫外線発光素子９（図２等参照、後述）の点灯等を行うための種々の操作指示が入力される複数の操作ボタン３が設けられている。なお、操作ボタン３の数や配置等は図示例に限定されない。 In addition, a plurality of operations in which various operation instructions are input to the outer peripheral portion of the main body case 1 to perform time setting instructions, lighting of an ultraviolet light emitting element 9 (see FIG. 2, etc., which will be described later) as a light source unit Button 3 is provided. The number and arrangement of the operation buttons 3 are not limited to the illustrated example.

本体ケース１は、腕時計１００の表面側（視認側、図２及び図３において上側）の開口部と、本体ケース１の裏面側（図２及び図３において下側）の開口部とを有している。そして、本体ケース１の表面側開口部には、透明なガラス等の材料で形成された風防部材４が防水リング４ａを介して表面側開口部を閉塞するように取り付けられている。一方、本体ケース１の裏面側開口部には、裏蓋部材５が防水リング５ａを介して裏面側開口部を閉塞するように取り付けられている。 The main body case 1 has an opening on the front side (viewing side, upper side in FIGS. 2 and 3) of the wristwatch 100 and an opening on the back side (lower side in FIGS. 2 and 3) of the main body case 1. ing. And the windshield member 4 formed with materials, such as transparent glass, is attached to the surface side opening part of the main body case 1 through the waterproof ring 4a so that the surface side opening part may be obstruct | occluded. On the other hand, the back cover member 5 is attached to the back surface side opening of the main body case 1 so as to close the back surface side opening through the waterproof ring 5a.

風防部材４の裏面側（視認側とは反対側、図２及び図３において下側）には、半透過性の反射部である第２の光反射部４１が設けられている。第２の光反射部４１は、後述する紫外線発光素子９（発光部）及び第１の光反射部８４よりも視認側に配置され、第１の光反射部８４によって反射された光が入射すると、この入射した光を拡散させて視認側とは反対側に拡散反射（乱反射）させ、少なくとも発光部８３に向けて照射するものである。
第２の光反射部４１は、例えば風防部材４の裏面側の表面にアルミニウムやクロム等の金属を蒸着することによりほぼ均一な膜厚となるように形成された金属蒸着層である。なお、第２の光反射部４１を形成する材料はここに例示したものに限定されない。また、第２の光反射部４１を形成する手法は蒸着に限定されず、被膜や層を形成するための各種手法を用いることができる。
なお、第２の光反射部４１には第１の光反射部８４によって反射された光のみならず、光源部である紫外線発光素子９から直接入射した光や文字板７等、他の部材により反射された光も入射するようになっており、第２の光反射部４１は、これらの光についても拡散させて視認側とは反対側に拡散反射（乱反射）させるようになっている。また、第２の光反射部４１は発光部８３のみでなく、第１の光反射部８４や文字板７等に対しても光を反射させる。このため、紫外線発光素子９から照射された光は、第２の光反射部４１の下で様々な経路で反射を繰り返し、各発光部８３に広く均一な光を照射することができる。 A second light reflecting portion 41 that is a semi-transmissive reflecting portion is provided on the rear surface side of the windshield member 4 (the side opposite to the viewing side, the lower side in FIGS. 2 and 3). The second light reflecting portion 41 is arranged on the visual recognition side with respect to the ultraviolet light emitting element 9 (light emitting portion) and the first light reflecting portion 84 described later, and when the light reflected by the first light reflecting portion 84 enters. The incident light is diffused and diffusely reflected (diffusely reflected) on the side opposite to the viewing side, and irradiated at least toward the light emitting unit 83.
The 2nd light reflection part 41 is a metal vapor deposition layer formed so that it might become a substantially uniform film thickness by vapor-depositing metals, such as aluminum and chromium, on the surface of the back surface side of the windshield member 4, for example. In addition, the material which forms the 2nd light reflection part 41 is not limited to what was illustrated here. Moreover, the method for forming the second light reflecting portion 41 is not limited to vapor deposition, and various methods for forming a film or a layer can be used.
The second light reflecting portion 41 is not limited to the light reflected by the first light reflecting portion 84, but also by other members such as light directly incident from the ultraviolet light emitting element 9 that is the light source portion and the dial 7. The reflected light is also incident, and the second light reflecting portion 41 diffuses these light and diffusely reflects (diffuse reflection) to the side opposite to the viewing side. Further, the second light reflecting portion 41 reflects light not only to the light emitting portion 83 but also to the first light reflecting portion 84 and the dial 7. For this reason, the light emitted from the ultraviolet light emitting element 9 is repeatedly reflected through various paths under the second light reflecting portion 41, and each light emitting portion 83 can be irradiated with a wide and uniform light.

本体ケース１の内部には、例えば樹脂等によって形成されたハウジング６が設けられている。ハウジング６には、指針１１である時針１１ａ、分針１１ｂを運針させる時計ムーブメント、各種電子部品を実装した回路基板（いずれも図示せず）等が組み込まれている。 A housing 6 made of, for example, resin is provided inside the main body case 1. The housing 6 incorporates a timepiece movement for moving the hour hand 11a and the minute hand 11b which are the hands 11, a circuit board (not shown) on which various electronic components are mounted.

ハウジング６の上側（視認側、図２及び図３において上側）には、文字板７が配置されている。
本実施形態において腕時計１００は、指針１１（時針１１ａ、分針１１ｂ）を備えるアナログ式の腕時計である。文字板７のほぼ中央部には、図示しない貫通孔が設けられており、この貫通孔には時計ムーブメントの内部機構側から風防部材４の設けられている側（図２及び図３において上側）に向けて指針１１（時針１１ａ、分針１１ｂ）を支持する軸部材１２が挿通されている。この軸部材１２が時計ムーブメントの駆動により回転すると、軸部材１２に支持された指針１１（時針１１ａ、分針１１ｂ）が文字板７の上方を運針し、後述する時字部８１，８２を指し示すことによって時刻が表示されるように構成されている。 On the upper side of the housing 6 (viewing side, upper side in FIGS. 2 and 3), a dial plate 7 is arranged.
In the present embodiment, the wristwatch 100 is an analog wristwatch provided with hands 11 (hour hand 11a, minute hand 11b). A through hole (not shown) is provided in the substantially central portion of the dial plate 7, and the through hole is provided on the side where the windshield member 4 is provided from the internal mechanism side of the timepiece movement (upper side in FIGS. 2 and 3). A shaft member 12 that supports the pointer 11 (the hour hand 11a and the minute hand 11b) is inserted therethrough. When the shaft member 12 is rotated by driving the timepiece movement, the hands 11 (the hour hand 11a and the minute hand 11b) supported by the shaft member 12 move the dial 7 above and point to time-shaped portions 81 and 82 to be described later. The time is displayed.

文字板７の上には、環状（リング状）に形成され内周面を有する枠状部材である見切り部材８が本体ケース１の内周面に沿って配置されている。
図４は、見切り部材８の斜視図である。
図４に示すように、本実施形態において、見切り部材８の上側（視認側、図２及び図３において上側）の面には、２時、４時、６時、８時、１０時、１２時に対応したアラビア数字を表す時字（アラビックインデックス）である時字部８１と、棒状の時字（バーインデックス）である時字部８２とが、交互にほぼ等間隔に設けられている。見切り部材８は、１２時を表す時字部８１が腕時計１００の上部（図１において上側）に位置し、６時を表す時字部８１が腕時計１００の下部（図１において下側）に位置するように文字板７の上に配置される。 On the dial 7, a parting member 8, which is a frame-like member formed in an annular shape (ring shape) and having an inner peripheral surface, is disposed along the inner peripheral surface of the main body case 1.
FIG. 4 is a perspective view of the parting member 8.
As shown in FIG. 4, in this embodiment, the upper surface (viewing side, upper side in FIGS. 2 and 3) of the parting member 8 is 2 o'clock, 4 o'clock, 6 o'clock, 8 o'clock, 10 o'clock, 12 A time character portion 81 which is a time character (Arabic index) representing Arabic numerals corresponding to the time and a time character portion 82 which is a bar-shaped time character (bar index) are alternately provided at substantially equal intervals. The parting member 8 has a time character portion 81 representing 12:00 located on the upper part (upper side in FIG. 1) of the wristwatch 100, and a time character portion 81 representing 6 o'clock located on the lower part (lower side in FIG. 1) of the wristwatch 100. It arrange | positions on the dial plate 7 so that it may do.

各時字部８１，８２の上側の面には、それぞれ発光素子から出力される光に反応して有色発光する発光部８３が設けられている。なお、発光部８３が設けられる位置は図示例に限定されない。各時字部８１，８２の上側の面全体に発光部８３が設けられていてもよいし、その一部である所定箇所に設けられていてもよい。また、発光部８３は全ての時字部８１，８２に設けられていなくてもよい。 A light emitting portion 83 that emits colored light in response to light output from the light emitting element is provided on the upper surface of each time character portion 81, 82. The position where the light emitting unit 83 is provided is not limited to the illustrated example. The light emitting portion 83 may be provided on the entire upper surface of each time character portion 81, 82, or may be provided at a predetermined location which is a part thereof. Further, the light emitting unit 83 may not be provided in all the time character portions 81 and 82.

発光部８３は、例えば紫外線発光素子（ブラックライト）９により出力される光（紫外線）に反応するインクを複数回塗布して層状に構成したものであり、紫外線発光素子（ブラックライト）９の点灯時に、通常光源によって照明された場合とは異なる発光色が浮かび上がるものである。なお、発光部８３は、時字部８１，８２の上側の面に塗り重ねて構成してもよいし、例えば時字部８１，８２の上側の面に凹部を形成してその中にインクを塗布したものであってもよい。
発光部８３の上面は透明なオーバーコート（図示せず）で覆われて保護されていることが好ましい。 The light emitting unit 83 is configured by applying a layer of ink that reacts with light (ultraviolet light) output from the ultraviolet light emitting element (black light) 9, for example, and turns on the ultraviolet light emitting element (black light) 9. Sometimes a different emission color emerges than when illuminated by a normal light source. The light emitting unit 83 may be configured by being applied over the upper surface of the time character portions 81 and 82. For example, a concave portion is formed on the upper surface of the time character portions 81 and 82, and ink is placed therein. It may be applied.
It is preferable that the upper surface of the light emitting portion 83 is covered and protected by a transparent overcoat (not shown).

これら発光部８３は、例えば、波長が３５０〜４２０ｎｍ、または２５４〜３６５ｎｍの紫外線に反応して有色発光し、紫外線が照射されない通常状態のときに透明な状態を呈するものである。すなわち、発光部８３は、紫外線発光素子９から出力された紫外線等が照射されると、これに反応して有色発光する。
この発光部８３の発光色は、緑（または黄色）、青、赤の３色を基本として、様々な色バリエーションがある。ここで、各発光部８３は、全て同じ発光色のものであってもよいが、例えばアラビックインデックスである時字部８１と、バーインデックスである時字部８２とで各発光部８３の発光色を異なっていてもよい。また、各時字部８１，８２毎にそれぞれ発光色が異なっていてもよい。 For example, the light emitting portions 83 emit colored light in response to ultraviolet light having a wavelength of 350 to 420 nm or 254 to 365 nm, and exhibit a transparent state in a normal state where no ultraviolet light is irradiated. That is, the light emitting unit 83 emits colored light in response to irradiation with ultraviolet rays or the like output from the ultraviolet light emitting element 9.
The emission color of the light emitting unit 83 is based on three colors of green (or yellow), blue, and red, and has various color variations. Here, the light emitting units 83 may all have the same light emission color. For example, the light emission color of each light emitting unit 83 includes a time character portion 81 that is an Arabic index and a time character portion 82 that is a bar index. May be different. Further, the light emission colors may be different for the respective time character portions 81 and 82.

また、見切り部材８の内周面の一部であって各時字部８１，８２における内側の面（腕時計１００の中央に向いている面）には、視認側（図２及び図３において上側）に向けて拡開する傾斜面が形成されており、この傾斜面上には、光源部である紫外線発光素子９から出力された光が入射すると、この入射した光を視認側（図２及び図３において上側）に反射させる第１の光反射部８４が配置されている。
第１の光反射部８４は、第２の光反射部４１と同様に、例えば風防部材４の裏面側の表面にアルミニウムやクロム等の金属を蒸着することによりほぼ均一な膜厚となるように形成された金属蒸着層である。なお、第１の光反射部８４を形成する材料はここに例示したものに限定されない。また、第１の光反射部８４を形成する手法は蒸着に限定されず、被膜や層を形成するための各種手法を用いることができる。
なお、本実施形態では、後述するように６時を示す時字部８１の下方に光源部である紫外線発光素子９が配置されるため、６時を示す時字部８１には、傾斜面及び第１の光反射部８４が設けられていないが、６時を示す時字部８１にも傾斜面及び第１の光反射部８４を設けてもよい。第１の光反射部８４は、紫外線発光素子９から出力された光が入射するのみでなく、第２の光反射部４１や他の第１の光反射部８４によって反射した光が入射した際にもこれを視認側に反射させるものであるため、６時を示す時字部８１にも傾斜面及び第１の光反射部８４を設けた場合には、これら他の反射部８４，４１によって反射された光をさらに視認側に反射させることができる。 Further, a part of the inner peripheral surface of the parting member 8 and an inner surface (a surface facing the center of the wristwatch 100) in each of the time character portions 81 and 82 are on the viewing side (the upper side in FIGS. 2 and 3). An inclined surface that expands toward the surface of the light emitting element 9 is formed. When light output from the ultraviolet light emitting element 9 that is a light source is incident on the inclined surface, the incident light is viewed on the viewing side (see FIG. 2 and FIG. 2). A first light reflecting portion 84 that is reflected upward) in FIG. 3 is disposed.
As with the second light reflecting portion 41, the first light reflecting portion 84 has a substantially uniform film thickness, for example, by vapor-depositing a metal such as aluminum or chromium on the back surface of the windshield member 4. It is the formed metal vapor deposition layer. In addition, the material which forms the 1st light reflection part 84 is not limited to what was illustrated here. The method for forming the first light reflecting portion 84 is not limited to vapor deposition, and various methods for forming a film or a layer can be used.
In the present embodiment, as will be described later, since the ultraviolet light emitting element 9 that is a light source unit is disposed below the time character portion 81 indicating 6 o'clock, the time character portion 81 indicating 6 o'clock has an inclined surface and Although the 1st light reflection part 84 is not provided, you may provide an inclined surface and the 1st light reflection part 84 also in the time-character part 81 which shows 6 o'clock. The first light reflecting portion 84 not only receives the light output from the ultraviolet light emitting element 9 but also when the light reflected by the second light reflecting portion 41 and the other first light reflecting portion 84 enters. In addition, since this is reflected to the viewer side, when the inclined surface and the first light reflecting portion 84 are also provided in the time character portion 81 indicating 6 o'clock, the other reflecting portions 84 and 41 The reflected light can be further reflected to the viewer side.

見切り部材８の一部であって、６時を示す時字部８１の両側部には、光源部である紫外線発光素子９から出力される光を透過させる光透過部としての切り欠き部８５が形成されている。なお、切り欠き部８５は、光源部である紫外線発光素子９に対応する部分の周囲の少なくとも一部に設けられていればよく、切り欠き部８５の形状等は図示例に限定されない。 A part of the parting member 8 is a notch 85 as a light transmitting part that transmits light output from the ultraviolet light emitting element 9 that is a light source part, on both sides of the hour character part 81 indicating 6 o'clock. Is formed. Note that the cutout portion 85 only needs to be provided in at least a part of the periphery of the portion corresponding to the ultraviolet light emitting element 9 that is the light source portion, and the shape of the cutout portion 85 is not limited to the illustrated example.

図５は、腕時計１００の６時側周辺を拡大し６時を示す時字部８１の一部を切り欠いた要部斜視図である。
図２及び図５に示すように、見切り部材８の６時を示す時字部８１が設けられている部分の下方には、光源部である紫外線発光素子９が配置されている。
紫外線発光素子９は、ブラックライトと呼ばれるものであり、例えば波長が２５４〜４２０ｎｍ（ナノメートル）の紫外線、又は波長が３７４〜３８９ｎｍの紫外線、好ましくは３６５ｎｍ付近の紫外線を発光する紫外線灯または紫外線発光ダイオード（ＬＥＤ）等で構成されている。
この紫外線発光素子９は、図示しない電極端子によってハウジング６内の回路基板と電気的に接続されている。
紫外線発光素子９から出力された光（紫外線）は、見切り部材８に設けられている第１の光反射部８４に入射して視認側に反射され、風防部材４に設けられている第２の光反射部４１に入射して拡散され、視認側とは反対側に拡散反射されて、少なくとも発光部８３に向けて照射される。また、光透過部としての切り欠き部８５から上方向に透過した光は直接第２の光反射部４１に入射して拡散され、視認側とは反対側に拡散反射される。これにより、紫外線発光素子９から出力された光が広く拡散し、効率よく均一に各発光部８３に照射される。 FIG. 5 is a perspective view of a main part in which a portion around the hour character portion 81 is enlarged by enlarging the vicinity of the 6 o'clock side of the wristwatch 100 to indicate 6 o'clock.
As shown in FIGS. 2 and 5, an ultraviolet light emitting element 9, which is a light source part, is disposed below the part of the parting member 8 where the hour character portion 81 indicating 6 o'clock is provided.
The ultraviolet light emitting element 9 is a so-called black light. For example, an ultraviolet lamp or ultraviolet light emitting light having a wavelength of 254 to 420 nm (nanometers), an ultraviolet light having a wavelength of 374 to 389 nm, preferably an ultraviolet light having a wavelength of around 365 nm. It is composed of a diode (LED) or the like.
The ultraviolet light emitting element 9 is electrically connected to the circuit board in the housing 6 by electrode terminals (not shown).
The light (ultraviolet light) output from the ultraviolet light emitting element 9 enters the first light reflecting portion 84 provided on the parting member 8, is reflected on the viewing side, and is provided on the windshield member 4. The light is incident on the light reflecting portion 41 and diffused, diffused and reflected on the side opposite to the viewing side, and irradiated at least toward the light emitting portion 83. Further, the light transmitted upward from the cutout portion 85 as the light transmitting portion is directly incident on the second light reflecting portion 41 and diffused, and is diffusely reflected on the side opposite to the viewing side. As a result, the light output from the ultraviolet light emitting element 9 is diffused widely, and the light emitting portions 83 are efficiently and uniformly irradiated.

なお、本実施形態では、光源部である紫外線発光素子９、発光部８３、被覆部材としての見切り部材８、見切り部材８の傾斜面に設けられた第１の光反射部８４、風防部材４に設けられた第２の光反射部４１を備えて発光表示装置が構成されている。 In the present embodiment, the ultraviolet light emitting element 9 as the light source unit, the light emitting unit 83, the parting member 8 as the covering member, the first light reflecting unit 84 provided on the inclined surface of the parting member 8, and the windshield member 4 are provided. A light emitting display device is configured by including the provided second light reflecting portion 41.

次に、本実施形態における発光表示装置及び電子機器である腕時計１００の作用について説明する。 Next, the operation of the light emitting display device and the wristwatch 100 which is an electronic device in the present embodiment will be described.

光源部である紫外線発光素子９の点灯を行うための操作ボタン３が操作されると、紫外線発光素子９から光（紫外線）が照射され、見切り部材８の傾斜面に設けられている各第１の光反射部８４に入射して視認側に反射される。また、光の一部は、光透過部としての切り欠き部８５から上方向に透過する。
第１の光反射部８４によって視認側に反射された光、又は切り欠き部８５から上方向に透過した光、その他文字板７と風防部材４との間に存する各部材によって視認側に反射された光は、風防部材４に設けられている第２の光反射部４１に入射して拡散され、視認側とは反対側に拡散反射される。
第２の光反射部４１によって反射された光、紫外線発光素子９から出力され切り欠き部８５から上方向に透過した光等は、少なくとも発光部８３に向けて照射され、各発光部８３は、この光に反応して各色に発光する。
また、紫外線発光素子９から出力された光や第１の光反射部８４、第２の光反射部４１等によって反射された光は、第１の光反射部８４、第２の光反射部４１その他の部材に入射して反射を繰り返し、文字板７と風防部材４との間で広く拡散して、効率よく均一に各発光部８３に照射される。 When the operation button 3 for turning on the ultraviolet light emitting element 9 which is a light source unit is operated, light (ultraviolet light) is irradiated from the ultraviolet light emitting element 9, and each first provided on the inclined surface of the parting member 8. Is incident on the light reflecting portion 84 and reflected to the viewing side. Further, part of the light is transmitted upward from the cutout portion 85 as a light transmission portion.
Light reflected on the viewing side by the first light reflecting portion 84, light transmitted upward from the notch portion 85, and other members existing between the dial 7 and the windshield member 4 are reflected on the viewing side. The incident light enters the second light reflecting portion 41 provided on the windshield member 4 and is diffused, and is diffusely reflected on the side opposite to the viewing side.
The light reflected by the second light reflecting portion 41, the light output from the ultraviolet light emitting element 9 and transmitted upward from the notch portion 85 is irradiated toward at least the light emitting portion 83, and each light emitting portion 83 is In response to this light, each color emits light.
In addition, the light output from the ultraviolet light emitting element 9 and the light reflected by the first light reflecting portion 84, the second light reflecting portion 41, and the like are the first light reflecting portion 84 and the second light reflecting portion 41. The light is incident on other members and repeatedly reflected, and diffuses widely between the dial 7 and the windshield member 4 so that the light emitting portions 83 are efficiently and uniformly irradiated.

以上のように、本実施形態によれば、光源部である紫外線発光素子９の上方を覆うように被覆部材としての見切り部材８を設けているため、視認側から見た際の外観を損なうことがなく、紫外線発光素子９の配置が制約されない。そして、紫外線発光素子９から出力された光を見切り部材８に設けられた第１の光反射部８４によって視認側に反射させ、この第１の光反射部８４によって反射された光を、風防部材４に設けられた半透過性の第２の反射部４１によって拡散させて視認側とは反対側に拡散反射させ、少なくとも発光部８３に向けて照射する。このため、見切り部材８によって紫外線発光素子９を視認側から被覆しても、第１の光反射部８４と第２の反射部４１とによって紫外線発光素子９からの光を発光部８３に導くことができ、紫外線発光素子９に広く光を照射することができる。
また、紫外線発光素子９から照射された光を第１の光反射部８４及び第２の反射部４１を介して間接的に発光部８３に導くため、紫外線発光素子９が１つである場合でも広く均一な光を各発光部８３に照射することができる。
さらに、第２の反射部４１は、半透過性の反射部であり、入射した光を拡散反射させて発光部８３に照射するものであるため、より広く均一な光を各発光部８３に隈なく照射することができる。
また、被覆部材である見切り部材８における、光源部に対応する部分の周囲、すなわち、本実施形態では、紫外線発光素子９を覆っている６時を示す時字部８１（６時のアラビックインデックス）の両側部分に、紫外線発光素子９から出力される光を透過させる光透過部としての切り欠き部８５が設けられている。このため、紫外線発光素子９から出力された光をこの切り欠き部８５から見切り部材８の上方に透過・拡散させることができ、６時を示す時字部８１及びその近傍に配置された時字部８１，８２の上に設けられている発光部８３や、第２の反射部４１等に、広く光を照射することができる。
また、被覆部材が、内周面を有し光源部である紫外線発光素子９の視認側を覆う見切り部材８（枠状部材）であり、第１の光反射部は、この見切り部材８（枠状部材）の内周面の一部（所定個所）に設けられている。このため、腕時計１００において別途被覆部材を設ける必要がなく、部品点数を増やすことなく光源部の被覆を実現することができる。
また、第１の光反射部８４は、枠状部材である見切り部材８の内周面の一部（所定個所）である時字部８１に設けられた傾斜面上に配置されている。このため、外観的な意匠を損なうことなく、紫外線発光素子９から照射された光を効率よく拡散させることができる。
また、本実施形態では、発光部８３に、時字（アラビックインデックス及びバーインデックス）が形成されているため、時刻表示となる時字部８１を紫外線発光素子９から照射された光によって照明し、各種の色に発色、発光させて、引き立たせ、美しい意匠を表現することができる。
また、本実施形態では、光源部として、紫外線発光素子（ブラックライト）を用いているため、発光部８３を各色に発色、発光させて、引き立たせ、美しい意匠を表現することができる。 As described above, according to the present embodiment, since the parting member 8 as the covering member is provided so as to cover the upper part of the ultraviolet light emitting element 9 that is the light source unit, the appearance when viewed from the viewing side is impaired. The arrangement of the ultraviolet light emitting elements 9 is not restricted. Then, the light output from the ultraviolet light emitting element 9 is reflected to the viewing side by the first light reflecting portion 84 provided on the parting member 8, and the light reflected by the first light reflecting portion 84 is reflected by the windshield member. 4 is diffused and reflected to the opposite side of the viewing side by the semi-transparent second reflecting portion 41 provided at 4, and is irradiated toward at least the light emitting portion 83. Therefore, even if the ultraviolet light emitting element 9 is covered from the viewing side by the parting member 8, the light from the ultraviolet light emitting element 9 is guided to the light emitting part 83 by the first light reflecting portion 84 and the second reflecting portion 41. Thus, the ultraviolet light-emitting element 9 can be widely irradiated with light.
Further, since the light emitted from the ultraviolet light emitting element 9 is indirectly guided to the light emitting part 83 through the first light reflecting portion 84 and the second reflecting portion 41, even when the number of the ultraviolet light emitting elements 9 is one. Each light emitting unit 83 can be irradiated with wide and uniform light.
Further, the second reflecting portion 41 is a semi-transmissive reflecting portion, and diffuses and reflects incident light to irradiate the light emitting portions 83, so that wider and uniform light is transmitted to each light emitting portion 83. Irradiation can be performed.
In addition, in the parting member 8 that is a covering member, around the portion corresponding to the light source portion, that is, in this embodiment, the hour character portion 81 (6 o'clock arabic index) indicating 6 o'clock covering the ultraviolet light emitting element 9. At both side portions, cutout portions 85 are provided as light transmitting portions that transmit light output from the ultraviolet light emitting element 9. Therefore, the light output from the ultraviolet light emitting element 9 can be transmitted and diffused from the cutout portion 85 to above the parting member 8, and the time character portion 81 indicating 6 o'clock and the time character disposed in the vicinity thereof. Light can be widely irradiated to the light emitting portion 83 provided on the portions 81 and 82, the second reflecting portion 41, and the like.
Further, the covering member is a parting member 8 (frame-like member) that has an inner peripheral surface and covers the viewing side of the ultraviolet light emitting element 9 that is a light source part, and the first light reflecting part is the parting member 8 (frame). Is provided in a part (predetermined location) of the inner peripheral surface of the member. For this reason, it is not necessary to provide a separate covering member in the wristwatch 100, and the light source portion can be covered without increasing the number of parts.
Further, the first light reflecting portion 84 is disposed on an inclined surface provided in the time character portion 81 which is a part (predetermined portion) of the inner peripheral surface of the parting member 8 which is a frame-shaped member. For this reason, the light irradiated from the ultraviolet light emitting element 9 can be efficiently diffused without impairing the appearance design.
Further, in the present embodiment, since the time character (Arabic index and bar index) is formed in the light emitting portion 83, the time character portion 81 serving as a time display is illuminated with the light emitted from the ultraviolet light emitting element 9, A variety of colors can be developed and emitted to enhance and enhance the appearance of beautiful designs.
Further, in the present embodiment, since an ultraviolet light emitting element (black light) is used as the light source unit, the light emitting unit 83 can be colored and emitted in each color to enhance and express a beautiful design.

なお、以上本発明の実施形態について説明したが、本発明は、かかる実施形態に限定されず、その要旨を逸脱しない範囲で、種々変形が可能であることは言うまでもない。 Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made without departing from the scope of the present invention.

例えば、本実施形態では、光源部としての紫外線発光素子９が１つ設けられている例を挙げて説明したが、紫外線発光素子９の数は特に限定されない。
また、紫外線発光素子が配置される位置は、腕時計１００の６時側に限定されない。
紫外線発光素子を腕時計１００の６時側以外の位置に配置する場合には、当該紫外線発光素子に対応する部分にも切り欠き部を設けて光が上方に透過できるように構成する。 For example, in the present embodiment, an example in which one ultraviolet light emitting element 9 as a light source unit is provided has been described, but the number of ultraviolet light emitting elements 9 is not particularly limited.
Further, the position where the ultraviolet light emitting element is disposed is not limited to the 6 o'clock side of the wristwatch 100.
When the ultraviolet light emitting element is disposed at a position other than the 6 o'clock side of the wristwatch 100, a portion corresponding to the ultraviolet light emitting element is provided with a notch so that light can be transmitted upward.

また、本実施形態においては、光源部として紫外線発光素子９を設ける場合を例として説明したが、光源部は発光部８３を発光させることのできるものであればよく、紫外線発光素子に限定されない。光源部は、例えば可視光線発光素子、赤外線発光素子等でもよい。光源部が可視光線発光素子、赤外線発光素子等である場合には、発光部８３を、光源部から照射されるそれぞれの光に反応して有色発光する材料により形成する。 In the present embodiment, the case where the ultraviolet light emitting element 9 is provided as the light source portion has been described as an example. However, the light source portion is not limited to the ultraviolet light emitting element as long as the light emitting portion 83 can emit light. The light source unit may be, for example, a visible light emitting element, an infrared light emitting element, or the like. When the light source unit is a visible light emitting element, an infrared light emitting element, or the like, the light emitting unit 83 is formed of a material that emits colored light in response to each light emitted from the light source unit.

また、本実施形態においては、発光部８３が見切り部材８に設けられた時字部８１，８２に設けられている場合を例示して説明したが、発光部８３が設けられる位置は時字部８１，８２に限定されない。例えば、文字板７の上や指針１１（時針１１ａ、分針１１ｂ等）の上等の所定の個所に設けられていてもよい。
また、発光部８３は、全ての時字部８１，８２に設けられていなくてもよい。
また、本実施形態では、発光部８３に数字である時字が形成されている場合を例としたが、発光部８３に形成されるものは数字に限定されず、例えばアルファベット等の文字や、各種ロゴマーク等の図形や記号等であってもよい。数字や文字、ロゴマーク等を発光部８３に形成することにより、光源部９からの光によりこれらを発光させ、引き立たせることができる。
なお、このように、時字部８１，８２、指針１１、文字板７等、様々な時計部品に発光部８３を設ける場合には、時刻を視認しやすくするために、少なくとも時字部８１，８２、指針１１と、文字板７上の図形とでは発光部８３の発光色が異なるようにすることが好ましい。例えば、文字板７の発光部８３は赤系色で発光し、時字部８１，８２や指針１８の発光部８３は青系色で発光するというように、それぞれ発光色が異なる方が時刻を確認しやすい。また、文字板７のマーク部分の発光部８３、時字部８１，８２の発光部８３、指針１１の発光部８３とで各発光色をそれぞれ異なるようにしてもよい。 Further, in the present embodiment, the case where the light emitting portion 83 is provided in the time character portions 81 and 82 provided in the parting member 8 is described as an example, but the position where the light emitting portion 83 is provided is the time character portion. It is not limited to 81,82. For example, it may be provided at a predetermined location such as on the dial 7 or on the hands 11 (hour hand 11a, minute hand 11b, etc.).
Moreover, the light emission part 83 does not need to be provided in all the time character parts 81 and 82. FIG.
Further, in the present embodiment, the case where a time character that is a number is formed in the light emitting unit 83 is taken as an example, but what is formed in the light emitting unit 83 is not limited to a number, for example, letters such as alphabets, It may be a figure such as various logo marks or a symbol. By forming numbers, letters, logo marks, and the like on the light emitting portion 83, these can be emitted by the light from the light source portion 9 and can be made to stand out.
In this way, in the case where the light emitting portion 83 is provided in various timepiece parts such as the time character portions 81 and 82, the pointer 11, the dial plate 7, etc., at least the time character portion 81, 82, it is preferable that the emission color of the light emitting portion 83 is different between the pointer 11 and the figure on the dial 7. For example, the light emitting portion 83 of the dial 7 emits light in a red color, and the time character portions 81 and 82 and the light emitting portion 83 of the pointer 18 emit light in a blue color. Easy to check. Further, the light emission colors of the light emitting portion 83 of the mark portion of the dial plate 7, the light emitting portion 83 of the time character portions 81 and 82, and the light emitting portion 83 of the pointer 11 may be different.

また、本実施形態では、被覆部材がリング状（環状）の枠状部材である見切り部材８である場合を例として説明したが、被覆部材の構成はこれに限定されない。
例えば、腕時計等、発光表示装置が適用される電子機器の視認側の面が四角形状である場合には、その外形に沿った形状の見切り部材を枠状部材として備える。
また、被覆部材は光源部を視認側から被覆することができるものであればよく、枠状部材に限定されない。例えば、光源部とその周辺のみを覆う庇部等であってもよい。 Moreover, although this embodiment demonstrated as an example the case where a coating | coated member is the parting member 8 which is a ring-shaped (annular) frame-shaped member, the structure of a coating | coated member is not limited to this.
For example, when a surface on the viewing side of an electronic device to which the light emitting display device is applied, such as a wristwatch, is a quadrangular shape, a parting member having a shape along the outer shape is provided as a frame-shaped member.
Moreover, the coating | coated member should just be what can coat | cover a light source part from the visual recognition side, and is not limited to a frame-shaped member. For example, it may be a flange that covers only the light source unit and its periphery.

また、本実施形態では、第１の光反射部が被覆部材である見切り部材８に設けられている時字部８１，８２に形成された傾斜面に設けられている例を示したが、第１の光反射部は、光源部（本実施形態では紫外線発光素子９）から出力された光が入射した際に、この入射した光を視認側に反射させることができるものであればよく、第１の光反射部を設ける位置等は実施形態に限定されない。例えば、見切り部材８の内周面全域に亘って第１の光反射部が形成されていてもよいし、見切り部材とは別個に第１の光反射部を設けてもよい。 Moreover, in this embodiment, although the 1st light reflection part showed the example provided in the inclined surface formed in the time character parts 81 and 82 provided in the parting member 8 which is a coating | coated member, The light reflecting portion 1 may be any member that can reflect the incident light to the viewing side when light output from the light source portion (ultraviolet light emitting element 9 in the present embodiment) is incident. The position of providing one light reflecting portion is not limited to the embodiment. For example, the first light reflecting part may be formed over the entire inner peripheral surface of the parting member 8, or the first light reflecting part may be provided separately from the parting member.

また、本実施形態では、光を透過させる光透過部として、被覆部材である見切り部材８における光源部（本実施形態では紫外線発光素子９）に対応する部分の周囲に切り欠き部８５を設けたが、光透過部は光源部（紫外線発光素子９）から照射された光を被覆部材の上方に透過させるものであればよく、切り欠き部に限定されない。例えば、光透過部としてスリット孔等を設けてもよい。 Further, in the present embodiment, a notch portion 85 is provided around the portion corresponding to the light source portion (ultraviolet light emitting element 9 in the present embodiment) in the parting member 8 that is a covering member as a light transmitting portion that transmits light. However, the light transmission part is not limited to the notch part as long as it transmits the light emitted from the light source part (ultraviolet light emitting element 9) to the upper side of the covering member. For example, you may provide a slit hole etc. as a light transmissive part.

また、本実施形態では、第２の光反射部が風防部材４の裏面側に蒸着された金属蒸着層である場合を例示したが、第２の光反射部は、発光部（本実施形態では紫外線発光素子９）及び第１の光反射部８４よりも視認側に配置された半透過性の反射部であって、少なくとも第１の光反射部８４によって反射された光が入射すると、この入射した光を拡散させて視認側とは反対側に拡散反射させ、少なくとも発光部（紫外線発光素子９）に向けて照射することができるものであればよく、第２の光反射部を設ける位置等は実施形態に限定されない。 Further, in the present embodiment, the case where the second light reflecting portion is a metal deposition layer deposited on the back surface side of the windshield member 4 is exemplified, but the second light reflecting portion is a light emitting portion (in the present embodiment, When the light reflected by at least the first light reflecting portion 84 is incident on the semi-transparent reflecting portion disposed on the viewing side from the ultraviolet light emitting element 9) and the first light reflecting portion 84, the incident light is incident. As long as the light is diffused and diffused and reflected to the side opposite to the viewing side and can be irradiated at least toward the light emitting part (ultraviolet light emitting element 9), the position where the second light reflecting part is provided, etc. Is not limited to the embodiment.

また、本実施形態では、時字が見切り部材８の上面に設けられている時字部８１である場合を例としたが、時字が設けられる位置はこれに限定されない。例えば時字を文字板上に印刷、貼着、蒸着、彫刻等の手段により形成してもよい。 Moreover, although the case where the time character is the time character part 81 provided in the upper surface of the parting member 8 was taken as an example in this embodiment, the position where the time character is provided is not limited to this. For example, time characters may be formed on a dial by means such as printing, sticking, vapor deposition, or engraving.

また、本実施形態においては、腕時計１００が指針を備えるアナログ式の腕時計である場合について説明したが、腕時計は、アナログ式に限定されない。例えば、液晶パネル等で構成された液晶表示部を備えるデジタル式の腕時計でもよいし、指針及び液晶表示部の双方を備える腕時計であってもよい。 In the present embodiment, the case where the wristwatch 100 is an analog wristwatch provided with a pointer has been described, but the wristwatch is not limited to an analog wristwatch. For example, a digital wristwatch provided with a liquid crystal display unit composed of a liquid crystal panel or the like, or a wristwatch provided with both a pointer and a liquid crystal display unit may be used.

また、本実施形態では、発光表示装置が適用される電子機器として腕時計を例示したが、発光表示装置が適用される電子機器は腕時計に限定されない。電子機器は、例えば携帯電話機、自動車の計器類など、各種機器であってもよい。 In this embodiment, a wristwatch is illustrated as an electronic device to which the light-emitting display device is applied.
