Description

本発明は、ＬＥＤにより文字板に文字を浮き出させ、時刻等を表示するＬＥＤ表示付き携帯機器の文字板構造に関するものである。   The present invention relates to a dial structure of a portable device with an LED display for displaying a time and the like by raising a character on a dial with an LED.

従来、ＬＥＤ（Ｌｉｇｔ Ｅｍｉｔｔｉｎｇ Ｄｉｏｄｅ：発光ダイオード）を発光源としてデジタル表示で時刻などを表示する腕時計や電子機器が知られている（たとえば、特許文献１、２参照）。また、アナログ時計において、透過性を持つ時計文字板の裏側から、ＬＥＤにより、時刻等の表示を浮き上がらせるアナログ腕時計が開示されている（たとえば、特許文献３参照）。この特許文献３では、ＬＥＤ表示機能つき腕時計の場合、遮光板の穴にＬＥＤを配置し、樹脂の透明文字板の印刷で、光を拡散させている。   2. Description of the Related Art Conventionally, wristwatches and electronic devices that display time and the like by digital display using an LED (Light Emitting Diode) as a light source are known (for example, see Patent Documents 1 and 2). In addition, an analog wristwatch has been disclosed in which an indication of time or the like is raised by an LED from the back side of a transparent timepiece dial (see, for example, Patent Document 3). In Patent Document 3, in the case of a wristwatch with an LED display function, an LED is disposed in a hole of a light shielding plate, and light is diffused by printing a transparent dial plate made of resin.

また、このようなＬＥＤ表示機能つき腕時計の文字板の固定は以下に示す図７のようにして行われている。文字板１００に凹部１００ａの形状を設け、この凹部１００ａと嵌合するように本体側のモジュール樹脂部材１１０に凸部１１０ａを設けることで相互の固定を行っている。   Further, the dial of the wristwatch with the LED display function is fixed as shown in FIG. The dial 100 is provided with the shape of the concave portion 100a, and the module resin member 110 on the main body side is provided with the convex portion 110a so as to be fitted to the concave portion 100a.

しかしながら、上記に示されるような特許文献３に開示されている技術にあっては、遮光板の穴にＬＥＤを配置し、樹脂の透明文字板の印刷で、ＬＥＤ光を拡散させているので、文字板の間を光が拡散し、文字のコントラストがはっきりしなかった。すなわち、樹脂文字板は、光が透過してしまい、色合い等の質感がなく、安っぽいイメージであった。   However, in the technique disclosed in Patent Document 3 as shown above, the LED is arranged in the hole of the light shielding plate, and the LED light is diffused by printing the resin transparent dial plate. The light diffused between the dials, and the contrast of the letters was not clear. In other words, the resin dial plate is a cheap image because light is transmitted therethrough and there is no texture such as color.

また、従来の樹脂文字板は、文字板足が設けられないため、樹脂ダボに圧入しているが、固定が安定しないいという問題点があった。   In addition, since the conventional resin dial is not provided with the dial foot, it is press-fitted into the resin dowel, but there is a problem that the fixing is not stable.

本発明は、上記に鑑みてなされたものであって、文字板の間で光が拡散されることなく、ＬＥＤのセグメント表示のコントラストをはっきりさせ、かつ文字板の質感を向上を図ることを目的とする。   The present invention has been made in view of the above, and it is an object of the present invention to clarify the contrast of the LED segment display without diffusing light between dials and to improve the texture of the dials. .

また、文字板を本体モジュールに安定して固定可能とすることを目的とする。   It is another object of the present invention to enable the dial to be stably fixed to the main body module.

The dial structure of the portable device is characterized in that a resin member capable of transmitting light is disposed in a transmitted light hole of the metal dial.

また、請求項２にかかる発明は、請求項１において、前記金属文字板の透過光穴周辺に段部を設け、前記透過光穴に凸形状の樹脂部材を配置したことを特徴とする。   According to a second aspect of the present invention, in the first aspect, a step portion is provided around the transmitted light hole of the metal dial, and a convex resin member is disposed in the transmitted light hole.

また、請求項３にかかる発明は、請求項１において、前記金属文字板の透過光穴に樹脂部材を配置した文字板において、文字板表面に、光透過性を有する塗料を用いて塗装をしたことを特徴とする。   According to a third aspect of the present invention, in the dial according to the first aspect, in which the resin member is disposed in the transmitted light hole of the metal dial, the surface of the dial is coated with a light-transmitting paint. It is characterized by that.

また、請求項４にかかる発明は、請求項１、２または３において、前記金属文字板の透過光穴に樹脂部材を配置した文字板において、前記樹脂部材の裏面に、光透過性を有する塗料を用いて塗装をしたことを特徴とする。   According to a fourth aspect of the present invention, in the dial according to the first, second, or third aspect, the resin member is disposed in the transmitted light hole of the metal dial plate. It is characterized by having been painted using.

また、請求項５にかかる発明は、請求項４において、前記金属文字板の透過光穴に樹脂部材を配置した文字板において、前記樹脂部材の裏面に、光透過性を有する白塗料を用いて塗装をしたことを特徴とする。   According to a fifth aspect of the present invention, in the dial according to the fourth aspect, in which the resin member is disposed in the transmitted light hole of the metal dial plate, a light-transmitting white paint is used on the back surface of the resin member. It is characterized by painting.

また、請求項６にかかる発明は、請求項１において、前記金属文字板に本体側の凹部と嵌合する凸部形状部材を設けたことを特徴とする。   According to a sixth aspect of the present invention, in the first aspect, the metal dial is provided with a convex shape member that fits into the concave portion on the main body side.

本発明にかかるＬＥＤ表示付き携帯機器は、金属文字板にＬＥＤの光透過用の穴を設け、ＬＥＤにより前記金属文字板に文字を浮き出させるＬＥＤ表示付き携帯機器の文字板構造において、金属文字板の透過光穴に、光を透過可能な樹脂部材を配置したので、文字板の間で光が拡散されることなく、ＬＥＤのセグメント表示のコントラストをはっきりさせることができるという効果を奏する。   The portable device with LED display according to the present invention is a metal dial plate in the dial structure of the portable device with LED display in which a hole for light transmission of the LED is provided in the metal dial plate, and the character is raised on the metal dial plate by the LED. Since the resin member capable of transmitting light is disposed in the transmitted light hole, the LED segment display contrast can be clarified without light being diffused between the dials.

以下に添付図面を参照して、この発明にかかるＬＥＤ表示付き携帯機器の文字板構造の最良な実施の形態を詳細に説明する。なお、以下に示す実施の形態は一例でありこれに限定されるものではない。   Exemplary embodiments of a dial structure of a portable device with LED display according to the present invention will be explained below in detail with reference to the accompanying drawings. In addition, embodiment shown below is an example and is not limited to this.

（実施の形態）
図１は、この実施の形態にかかるＬＥＤ表示付き携帯機器の文字板構造を用いた腕時計の構成例を示す説明図である。この図１において、腕時計ケース１０の表側に風防ガラス１１を固着し、裏側に裏ブタ１２をねじ付けて取り付ける。裏ブタ１２は、非磁性材であり、プラスチックや強磁性体ではない金属を用いて作製される。腕時計ケース１０内には、アナログムーブメント１３を樹脂製の中枠１４で固定して収納する。ムーブメント１３には、円盤状の回路基板１６を重ね合わせる。回路基板１６には、たとえば縦が１．６ｍｍ以下、横が０．８ｍｍ以下で、厚さ０．８ｍｍ以下の薄型チップＬＥＤ１７（デジタル表示用ＬＥＤ）を複数取り付ける。 (Embodiment)
FIG. 1 is an explanatory diagram showing a configuration example of a wristwatch using a dial structure of a portable device with an LED display according to this embodiment. In FIG. 1, a windshield glass 11 is fixed to the front side of a watch case 10 and a back cover 12 is attached to the back side by screwing. The back cover 12 is a non-magnetic material, and is manufactured using a metal that is not plastic or ferromagnetic. In the watch case 10, an analog movement 13 is fixed and stored with a resin inner frame 14. A disc-shaped circuit board 16 is overlaid on the movement 13. For example, a plurality of thin chip LEDs 17 (digital display LEDs) having a vertical length of 1.6 mm or less, a horizontal size of 0.8 mm or less, and a thickness of 0.8 mm or less are attached to the circuit board 16.

そして、薄型チップＬＥＤ１７を用いて１つのセグメント１８を構成し、デジタル数値で時刻を表示可能になるように平面的に配置する。回路基板１６には、中心に中心孔をあけ、その中心孔を挟んで上下に１つずつ設けた薄型チップＬＥＤ１７を用いてコロンを構成し、そのコロンを挟んで左右にセグメントを２つずつ振り分けて配置する。   Then, one segment 18 is configured using the thin chip LED 17 and is arranged in a plane so that the time can be displayed with a digital numerical value. The circuit board 16 is formed with a central hole in the center, and a thin chip LED 17 provided one above and below the central hole to form a colon, and two segments are distributed to the left and right across the colon. Arrange.

回路基板１６は、それより薄い遮光板２２に重ねて取り付け、その遮光板２２で支持する。遮光板２２には、表裏を貫通して複数の光透過孔２３を開ける。光透過孔２３は、回路基板１６の各薄型チップＬＥＤ１７に対向して開け、光透過孔２３ごとにそれぞれ薄型チップＬＥＤ１７を各１つずつ対応して設け、遮光板２２の裏側に回路基板１６を取り付けたときに薄型チップＬＥＤ１７の発光面が光透過孔２３ごとに合致するように構成する。そして、遮光板２２に回路基板１６を重ね合わせても、たとえば厚さ１．５ｍｍ以下となるように構成する。   The circuit board 16 is attached to the light shielding plate 22 thinner than the circuit board 16 and supported by the light shielding plate 22. A plurality of light transmission holes 23 are opened through the front and back of the light shielding plate 22. The light transmission holes 23 are opened to face the thin chip LEDs 17 of the circuit board 16, and one thin chip LED 17 is provided for each light transmission hole 23, and the circuit board 16 is provided on the back side of the light shielding plate 22. The light emitting surface of the thin chip LED 17 is configured to match each light transmitting hole 23 when attached. Then, even if the circuit board 16 is overlaid on the light shielding plate 22, the thickness is, for example, 1.5 mm or less.

遮光板２２は，遮光性の高い黒色などの濃い色の樹脂材料を用いて形成する。遮光板２２は，表面に時刻数字や時刻などの時刻表示を有する金属文字板２４を重ね合わせる。   The light shielding plate 22 is formed using a dark color resin material such as black having a high light shielding property. The light shielding plate 22 has a metal dial plate 24 having a time display such as a time number and time superimposed on the surface.

ここで、金属文字板２４の詳細な構成例について図２〜図を参照し説明する。図２はこの実施の形態にかかる金属文字板２４の全体構成を示す説明図である。この図２に図示する符号２４ａはデジタル表示のためＬＥＤ光を透過させる透過光孔、符号２４ｂは時字印刷、符号２４ｃはアナログセンター孔、符号２４ｄは文字板足である。   Here, a detailed configuration example of the metal dial 24 will be described with reference to FIGS. FIG. 2 is an explanatory view showing the overall configuration of the metal dial 24 according to this embodiment. Reference numeral 24a shown in FIG. 2 is a transmission light hole for transmitting LED light for digital display, reference numeral 24b is time-character printing, reference numeral 24c is an analog center hole, and reference numeral 24d is a dial foot.

図３は図２における金属文字板２４の積層構成例を示し、図４はこの図３のＡ部を拡大して示す図である。また、図５に光を透過可能な材質でなる凸形状の樹脂部材の構成例を示し、図６は金属文字板２４の斜視図である。これらの図において、金属文字板２４の透過光孔２４ａに、光を透過可能な材質でなる樹脂部材４０を配置する。すなわち、この例では、金属文字板２４の透過光孔２４ａの周辺に文字板段部２４ｅを設け、透過光孔２４ａの部分に凸形状の樹脂部材４０を配置する。なお、この樹脂部材４０の固定には圧入、接着などを用いる。また、金属文字板２４は、図３の下部に示すように、文字板足２４ｄは本体側モジュール部分に圧入されることで固定される。   FIG. 3 shows an example of a laminated structure of the metal dial plate 24 in FIG. 2, and FIG. 4 is an enlarged view of a portion A in FIG. FIG. 5 shows a configuration example of a convex resin member made of a material that can transmit light, and FIG. 6 is a perspective view of the metal dial 24. In these drawings, a resin member 40 made of a material capable of transmitting light is disposed in the transmitted light hole 24 a of the metal dial 24. That is, in this example, the dial plate step 24e is provided around the transmitted light hole 24a of the metal dial 24, and the convex resin member 40 is disposed in the transmitted light hole 24a. The resin member 40 is fixed by press-fitting or bonding. Further, as shown in the lower part of FIG. 3, the metal dial 24 is fixed by press-fitting the dial foot 24d into the module part on the main body side.

また、図４に示すように、金属文字板２４の表面に、光透過性を有する文字板塗装４１を施す。なお、この文字板塗装４１は、イオンコーティイングなどであってもよい。金属板への塗装のため、色合い等の質感が出しやすく、塗料の選定も自由度が大きい。樹脂部材４０の裏面には、光透過性を持つ塗料材を用いて樹脂部材塗装４２を行い、樹脂部材４０内部での光の拡散を良好にさせる。このとき、白色の塗装であれば、樹脂部材４０での光拡散が大きくなり、さらに見栄えがよくなる。   Further, as shown in FIG. 4, a dial coating 41 having light transmittance is applied to the surface of the metal dial 24. The dial coating 41 may be ion coating or the like. Because the paint is applied to the metal plate, it is easy to create textures such as shades, and the choice of paint is great. A resin member coating 42 is applied to the back surface of the resin member 40 using a light-transmitting coating material so that light diffusion inside the resin member 40 is improved. At this time, if the paint is white, light diffusion in the resin member 40 is increased, and the appearance is further improved.

つぎに、図１に戻ってさらに説明する。デジタル表示用の薄型チップＬＥＤ１７を点灯したときのみ薄型チップＬＥＤ１７のデジタル表示を金属文字板２４を透して視認し得る光透過率で形成する。好ましくは、その光透過率を１〜７０％とする。そして、金属文字板２４の周縁を腕時計ケース１０の見切り部に当てて、全体を腕時計ケース１０内に収納するとともに、文字板足２４ｄ本体側モジュール部分の凹部に位置決めし、圧入して固定する。   Next, referring back to FIG. Only when the thin chip LED 17 for digital display is turned on, the digital display of the thin chip LED 17 is formed with a light transmittance that can be seen through the metal dial 24. Preferably, the light transmittance is 1 to 70%. Then, the periphery of the metal dial plate 24 is applied to the parting portion of the watch case 10, and the whole is housed in the watch case 10, and positioned in the concave portion of the dial plate foot 24d main body side, and is press-fitted and fixed.

金属文字板２４の裏側に遮光板２２を備え、その遮光板２２の裏側に回路基板１６を配置し、回路基板１６の裏側に、回路基板１６上の薄型チップＬＥＤ１７を配置する。運針軸１５は、回路基板１６の中心孔から遮光板２２の中心孔を通して金属文字板２４まで貫通して先端を金属文字板２４の表面に露出する。そして、先端に、時針２５、分針２６、秒針２７を取り付ける。   A light shielding plate 22 is provided on the back side of the metal dial plate 24, the circuit board 16 is arranged on the back side of the light shielding plate 22, and the thin chip LED 17 on the circuit board 16 is arranged on the back side of the circuit board 16. The needle movement shaft 15 penetrates from the central hole of the circuit board 16 to the metal dial plate 24 through the central hole of the light shielding plate 22, and the tip is exposed on the surface of the metal dial plate 24. Then, the hour hand 25, the minute hand 26, and the second hand 27 are attached to the tip.

そのようなムーブメント１３の裏ブタ１２側には、充電回路を設け、コイン型の二次電池３０をムーブメント１３と重ね合わせて配置するとともに、その二次電池３０の周囲を囲むようにコイルボビン３１に環状に巻き付けて二次コイル３２を取り付ける。つまり、二次電池３０と二次コイル３２を、腕時計ケース１０内において同一平面に配置する。   A charging circuit is provided on the back cover 12 side of such a movement 13, and a coin-type secondary battery 30 is disposed so as to overlap the movement 13, and the coil bobbin 31 is surrounded by the periphery of the secondary battery 30. The secondary coil 32 is attached in a ring shape. That is, the secondary battery 30 and the secondary coil 32 are arranged on the same plane in the watch case 10.

また、腕時計ケース１０内において、回路基板１６の裏側には、ムーブメント１３と同一平面に、薄型チップＬＥＤ１７を駆動するＬＥＤ駆動回路３３を取り付ける。このＬＥＤ駆動回路３３は、外部操作に基づき薄型チップＬＥＤ１７のすべてを点灯するＬＥＤ駆動機能を備える。また、外部操作に基づき、ストップウォッチ、アラーム、タイマなどの付加時計機能を働かせる機能を備える。   In the wristwatch case 10, an LED drive circuit 33 that drives the thin chip LED 17 is attached to the back side of the circuit board 16 in the same plane as the movement 13. The LED drive circuit 33 has an LED drive function for lighting all the thin chip LEDs 17 based on an external operation. In addition, it has a function to activate additional clock functions such as a stopwatch, an alarm, and a timer based on an external operation.

他方、この実施の形態にかかる腕時計は、外部にリューズ３５を取り付ける巻真３６を、腕時計ケース１０を貫通して挿入してムーブメント１３内に入れる。また、図示を省略するが、外端にスイッチを取り付ける操作軸を、同様に腕時計ケース１０を貫通して挿入してムーブメント１３内に入れる。   On the other hand, in the wristwatch according to this embodiment, a winding stem 36 for attaching a crown 35 to the outside is inserted through the wristwatch case 10 and placed in the movement 13. Although not shown, an operation shaft for attaching a switch to the outer end is similarly inserted through the watch case 10 and placed in the movement 13.

そして、図示するようなアナログ腕時計では、通常時は、デジタル表示用の薄型チップＬＥＤ１７を点灯せず、二次電池３０でムーブメント１３を駆動して針２５〜２７を回転し、金属文字板２４の時刻表示を指して時刻をアナログ表示する。必要に応じ、適宜外部操作により、デジタル表示用の薄型チップＬＥＤ１７を点灯してその光を遮光板２２の光透過孔２３で導光して金属文字板２４を透し、時刻、月日、曜日などをデジタル表示する。時刻修正時は、リューズ３５を操作して巻真３６を介してムーブメント１３を動かし、針２５〜２７を回す。   In an analog wristwatch as shown in the figure, normally, the thin chip LED 17 for digital display is not turned on, the movement 13 is driven by the secondary battery 30 to rotate the hands 25 to 27, and the metal dial 24 Point to the time display and display the analog time. If necessary, the digital display thin chip LED 17 is turned on by an appropriate external operation, and the light is guided through the light transmission hole 23 of the light shielding plate 22 to pass through the metal dial plate 24. Etc. are digitally displayed. When the time is adjusted, the crown 35 is operated to move the movement 13 via the winding stem 36, and the hands 25 to 27 are turned.

このように、アナログ表示とともにデジタル表示を行なうことができる腕時計において、通常時は、デジタル表示用の薄型チップＬＥＤ１７を点灯せず、時刻をアナログ表示し、金属文字板２４を隠してデジタル表示用の薄型チップＬＥＤ１７が見えないようにし、金属文字板２４にデジタル表示窓を開けたりする必要をなくしてデザイン上の制約を少なくし、デザイン上の多様性を確保することができる。また、必要に応じ，種々の色で、暗いところでも明るく表示し、表示の見栄えが悪いとか暗いところでは見にくいとかの液晶パネル特有の欠点を解消する一方、デジタル表示を金属文字板２４いっぱいに大きく見やすく表示することができる。   As described above, in a wristwatch capable of performing digital display together with analog display, normally, the thin display LED 17 for digital display is not lit, the time is displayed in analog, the metal dial 24 is hidden, and digital display is used. It is possible to prevent the thin chip LED 17 from being seen, eliminate the need to open a digital display window on the metal dial plate 24, reduce design restrictions, and ensure design diversity. In addition, if necessary, the display is brightly displayed in various colors, even in dark places, eliminating the disadvantages inherent to liquid crystal panels such as poor display or difficult to see in dark places. It can be displayed easily.

回路基板１６の中心孔を挟んでデジタル表示用の薄型チップＬＥＤ１７を用いて構成したコロンを設け、そのコロンを挟んで、デジタル表示用の薄型チップＬＥＤ１７を用いて構成したセグメント１８を２つずつ振り分けて配置するので、金属文字板２４に近い大きさの回路基板１６を用い、その回路基板１６いっぱいにセグメント１８を配置することにより金属文字板２４を有効に利用してデジタル表示を大きく見やすくすることができる。   A colon configured using the thin chip LED 17 for digital display is provided across the center hole of the circuit board 16, and the segments 18 configured using the thin chip LED 17 for digital display are distributed two by two across the colon. Since the circuit board 16 having a size close to the metal dial plate 24 is used and the segments 18 are arranged over the circuit board 16, the metal dial plate 24 can be effectively used to make the digital display easier to see. Can do.

また、金属文字板２４、遮光板２２、回路基板１６、アナログムーブメント１３、ＬＥＤ駆動回路３３などの構成部品をコンパクトにまとめて腕時計ケース１０内に収納し、腕時計全体を小型化することができる。このアナログ腕時計では、運針軸１５が貫通する回路基板１６を中心孔を挟んで薄型チップＬＥＤ１７を設け、それらのＬＥＤを用いてコロン１９を構成することで、アナログ表示とともにデジタル表示も文字板いっぱいに表示可能とし、アナログ表示とデジタル表示をともに大きく見やすく表示することができる。   In addition, components such as the metal dial plate 24, the light shielding plate 22, the circuit board 16, the analog movement 13, and the LED drive circuit 33 can be compactly stored in the watch case 10 to reduce the size of the entire watch. In this analog wristwatch, a thin chip LED 17 is provided with a circuit board 16 through which the hand movement shaft 15 passes sandwiching a center hole, and a colon 19 is formed by using these LEDs, so that a digital display as well as an analog display fills the dial. Display is possible, and both analog display and digital display can be displayed large and easy to see.

また、ＬＥＤ駆動回路３３に、外部操作にしたがって薄型チップＬＥＤ１７のすべてを点灯するＬＥＤ駆動機能を備えるので、たとえば暗いところで鍵穴などが見えにくいときなど、明かりが必要なところでは、外部操作によりＬＥＤ駆動回路３３を働かせて薄型チップＬＥＤ１７のすべてを点灯することができる。そして、二次電池３０を電源として風防ガラス１１を透かして外部を照射し、時刻など薄型チップＬＥＤ１７をそのまま照明用としても利用し、別途照明光源を備えることにより大型化したり見栄えを悪くしたりすることなく、まわりを照らすことができる。   Further, since the LED drive circuit 33 has an LED drive function for lighting all of the thin chip LEDs 17 according to an external operation, the LED drive is performed by an external operation when a light is necessary, for example, when a keyhole is difficult to see in a dark place. All the thin chip LEDs 17 can be lit by operating the circuit 33. Then, the secondary battery 30 is used as a power source to illuminate the outside through the windshield glass 11, and the thin chip LED 17 such as the time is also used for illumination as it is, and by providing a separate illumination light source, the size is increased or the appearance is deteriorated. Without illuminating the surroundings.

さらに、ＬＥＤ駆動回路３３に、スイッチ（不図示）の外部操作にしたがって、ストップウォッチ、アラーム、タイマなどの付加時計機能を働かせるＬＥＤ駆動態様を備えるので、アナログ表示とともにデジタル表示を行なうことができる腕時計において、さらに機能アップして付加機能を高めることができる。   Further, the LED driving circuit 33 is provided with an LED driving mode in which additional clock functions such as a stopwatch, an alarm, and a timer are operated in accordance with an external operation of a switch (not shown), so that a wristwatch capable of performing digital display as well as analog display. In addition, the function can be further improved to increase the additional function.

不図示のスイッチをさらにもう一度外部操作すると、薄型チップＬＥＤ１７を消灯する。もちろん、残照時間を設定してスイッチ操作後一定時間が経過した後、薄型チップＬＥＤ１７を自動的に消灯するようにしてもよい。   When the switch (not shown) is further externally operated again, the thin chip LED 17 is turned off. Of course, the thin chip LED 17 may be automatically turned off after a certain time has elapsed after the switch operation after setting the afterglow time.

ところで、この例における腕時計では、使用により二次電池３０の電池容量が低下したときは、不図示の充電器上に載せて電磁誘導方式を用いて充電する。つまり、ＡＣコードを介して供給されるＡＣ電流を流して充電器の一次コイルで交流磁界を発生させ、この交流磁界によりこの腕時計の二次コイル３２に交流電流を発生させ、整流回路で整流して直流電源として二次電池３０を充電する。   By the way, in the wristwatch in this example, when the battery capacity of the secondary battery 30 decreases due to use, it is placed on a charger (not shown) and charged using an electromagnetic induction method. In other words, an AC current supplied via an AC cord is passed to generate an AC magnetic field at the primary coil of the charger, an AC current is generated at the secondary coil 32 of the wristwatch by the AC magnetic field, and the current is rectified by a rectifier circuit. Then, the secondary battery 30 is charged as a DC power source.

電源として二次電池３０を使用するので、薄型チップＬＥＤ１７を多用することにより電池がなくなっても電池交換をすることなく充電するだけでよいので、電池寿命を気にする必要なく、かつ電池交換の煩わしさや費用を気にすることなく、照明機能を存分に使うことができる。これにより、液晶パネルに比べて消費電力の大きいＬＥＤを用いてデジタル表示を行なうことによる欠点を解消することができる。   Since the secondary battery 30 is used as a power source, it is only necessary to charge the battery without replacing the battery even if the battery is exhausted by using the thin chip LED 17, so there is no need to worry about the battery life and the battery replacement. The lighting function can be fully used without worrying about bothersomeness and expense. Thereby, the fault by performing a digital display using LED with large power consumption compared with a liquid crystal panel can be eliminated.

なお、ここでは、電磁誘導方式を用いて充電回路の二次電池３０を充電したが、二次電池３０を太陽電池や、直接電源端子を接続して充電することにしてもよい。二次コイル３２を備え、電磁誘導方式を用いて二次電池３０を充電可能とすると、デザイン上の制約を受けないとともに、防水構造を複雑にすることなく、簡単かつ確実な充電が可能となる。   Here, the secondary battery 30 of the charging circuit is charged using the electromagnetic induction method, but the secondary battery 30 may be charged by connecting a solar battery or a direct power supply terminal. If the secondary coil 32 is provided and the secondary battery 30 can be charged using the electromagnetic induction method, it is possible to perform simple and reliable charging without being restricted in design and without complicating the waterproof structure. .

このように以上説明してきたＬＥＤにより文字板に文字を浮き出させる腕時計によれば、金属文字板２４にＬＥＤ光の透過光孔２４ａを設けたことにより、ＬＥＤによるゼグメント表示のコントラストが向上する。さらに、従来における樹脂文字板は、文字板足が設けられないため、樹脂ダボに圧入しているので、固定が安定しなかったが、この実施の形態における金属文字板２４では、文字板足２４ｄが設けられるため、金属文字板２４の固定が安定する。   As described above, according to the wristwatch in which the character is raised on the dial by the LED, the transmission light hole 24a for the LED light is provided in the metal dial 24, thereby improving the contrast of the segment display by the LED. Further, since the conventional resin dial is not provided with the dial foot and is press-fitted into the resin dowel, the fixing is not stable. However, in the metal dial 24 in this embodiment, the dial foot 24d is not stable. Is provided, the metal dial 24 is fixed stably.

また、金属文字板２４の透過光穴に樹脂部材４０を配置したことにより、ＬＥＤが外部より直接見えなくなり、見栄えがよくなる。さらに、金属文字板２４の透過光穴周辺に文字板段部２４ｅを設け、穴部に凸形状の樹脂部材４０を配置したので、樹脂部材４０の取り付け性が向上する。   Further, by arranging the resin member 40 in the transmitted light hole of the metal dial plate 24, the LED is not directly visible from the outside, and the appearance is improved. Furthermore, since the dial plate step portion 24e is provided around the transmitted light hole of the metal dial plate 24 and the convex resin member 40 is disposed in the hole portion, the mounting property of the resin member 40 is improved.

また、従来の樹脂文字板では、光が透過してしまい、色合い等の質感がなく、安っぽいイメージであったが、この実施の形態では、金属文字板２４の文字板表面に、光透過性をもつ、塗装をしたので、文字板の質感が大幅に向上する。さらに、金属文字板２４への塗装のため、色合い等の質感が出しやすく、塗料の選定における自由度が高くなる。また、樹脂部材４０の裏面に、光透過性をもつ塗装をしたので、樹脂部材４０内部での光の拡散ができ、セグメントの見栄えがよくなる。また、樹脂部材４０の裏面に、光透過性をもつ、白塗装をしたので、光の拡散がさらに良くなる。   In addition, in the conventional resin dial plate, light is transmitted and there is no texture such as color, and it is a cheap image. However, in this embodiment, the dial surface of the metal dial plate 24 is made light transmissive. Since it has been painted, the texture of the dial is greatly improved. Furthermore, because the paint is applied to the metal dial plate 24, it is easy to produce a texture such as a hue, and the degree of freedom in selecting a paint is increased. Further, since the light-transmitting coating is applied to the back surface of the resin member 40, light can be diffused inside the resin member 40, and the appearance of the segments is improved. In addition, since the back surface of the resin member 40 is coated with light and white, light diffusion is further improved.

以上により、先に述べた従来のＬＥＤ表示機能つき腕時計において、文字のコントラストがはっきりしない、文字板の色合い等の質感がなく、安っぽいイメージとなる、といった問題点や、樹脂文字板の固定が安定しないといった問題点の解消が実現する。   As described above, in the conventional wristwatch with LED display function described above, the character contrast is not clear, there is no texture such as the color of the dial, and a cheap image is obtained, and the resin dial is fixed stably. This eliminates the problem of not doing so.

以上のように、本発明にかかるＬＥＤ表示付き携帯機器の文字板構造は、デジタル表示の腕時計、携帯機器に有用であり、特に、金属文字板を用いてＬＥＤ表示する小型の機器に適している。   As described above, the dial structure of the portable device with LED display according to the present invention is useful for digital display wristwatches and portable devices, and is particularly suitable for small devices that display LEDs using a metal dial. .
