Description

この発明は、発光素子を用いて電子機器の動作状態や機能を表示する発光表示部を備えた電子機器に関するものである。   The present invention relates to an electronic device including a light emitting display unit that displays an operation state and a function of the electronic device using a light emitting element.

図6(a),(b)は従来の発光素子を用いた発光表示部を備えた電子機器の縦断側面図及び縦断正面図を示し、図7(a),(b)は従来の電子機器の発光表示部の分解斜視図及び図6(a)のA部拡大図を示す。図において、1は内部に電子機器本体部2を内蔵するとともに、プリント板3を内蔵・保持したケースであり、ケース1は樹脂により形成され、プリント板3には発光素子4が前面側に実装され、ケース1における発光素子4の前面には発光素子4からの光をケース1の前面側に導く開孔部5aが形成された表示部ケース5が設けられ、表示部ケース5の前面には表示パネル6が被せられ、発光表示部7が形成される。表示パネル6には動作状態や機能が文字や図柄で表記される。表示パネル6及び表示部ケース5は樹脂により形成され、内蔵するプリント板3の発光素子4の形状や位置に合わせて、専用の形状に成形されている。従って、発光素子4のレイアウトは決まっているので、表示部ケース5及び表示パネル6の形状も決まっている。また、表示パネル6には透明スモーク材が使用され、発光素子4の発光のみを際立たせて透過させるとともに、発光素子4自体は見えにくくしている。   6A and 6B are a longitudinal side view and a longitudinal front view of an electronic apparatus provided with a light emitting display unit using a conventional light emitting element, and FIGS. 7A and 7B are conventional electronic apparatuses. The disassembled perspective view of the light emission display part of FIG. 6 and the A section enlarged view of Fig.6 (a) are shown. In the figure, reference numeral 1 denotes a case in which an electronic device main body 2 is built in and a printed board 3 is built in and held. The case 1 is made of resin, and a light emitting element 4 is mounted on the printed board 3 on the front side. In addition, a display unit case 5 is provided on the front surface of the light emitting element 4 in the case 1. The display unit case 5 is provided with an opening 5 a that guides light from the light emitting element 4 to the front surface side of the case 1. The display panel 6 is covered and the light emitting display portion 7 is formed. On the display panel 6, the operating state and functions are written in characters and symbols. The display panel 6 and the display unit case 5 are made of resin, and are formed in a dedicated shape in accordance with the shape and position of the light emitting element 4 of the built-in printed board 3. Accordingly, since the layout of the light emitting elements 4 is determined, the shapes of the display unit case 5 and the display panel 6 are also determined. Further, a transparent smoke material is used for the display panel 6 so that only the light emission of the light emitting element 4 is made to stand out and transmitted, and the light emitting element 4 itself is difficult to see.

The prior art document information related to the invention of this application includes the following.
Japanese Utility Model Publication No. 6-23284 Japanese Utility Model Publication No. 6-36162 JP 2003-15562 A JP 2003-279388 A

ところで、樹脂により成形する表示部ケース5や表示パネル6は専用の成形金型が必要であるため、多量に生産されるプリント板3の発光素子4の種類や位置に合わせて、専用の成形金型を製作している。しかしながら、図8(a),(b)に示すように、発光素子4の種類や位置が異なる異種プリント板3においては、小型発光素子4の他に通常発光素子8が設けられ、生産量が少ない場合、図8(c)に示すように、一部の成形金型を新規に製作して、発光素子4,8の位置に合わせた表示部ケース5や表示パネル6を成形していた。しかし、しかし、この場合、生産量に対する金型費用が大きくなり、コストアップになった。又、生産量が少ない異種プリント板3用の表示部ケース5や表示パネル6の全部を新たな成形金型を用いて成形することは、コスト的に不可能であるので、樹脂以外の材料により製作することとなり、機種としてのデザインの統一性が保てず、機種の商品価値が低下した。   By the way, since the display unit case 5 and the display panel 6 molded with resin require a dedicated molding die, the dedicated molding die is matched to the type and position of the light emitting element 4 of the printed board 3 to be produced in large quantities. I am making a mold. However, as shown in FIGS. 8A and 8B, in the dissimilar printed board 3 in which the types and positions of the light emitting elements 4 are different, the normal light emitting elements 8 are provided in addition to the small light emitting elements 4, and the production amount is reduced. In the case where the number is small, as shown in FIG. 8C, some of the molding dies are newly manufactured, and the display unit case 5 and the display panel 6 are formed in accordance with the positions of the light emitting elements 4 and 8. However, in this case, the mold cost for the production volume is increased, resulting in an increase in cost. Further, since it is impossible in cost to form all of the display unit case 5 and the display panel 6 for the different kind of printed board 3 with a small production amount using a new molding die, As a result, the unity of the design as a model could not be maintained, and the product value of the model decreased.

この発明は上記のような課題を解決するために成されたものであり、表示部ケースや表示パネルに汎用性を持たせることにより、表示部ケースや表示パネルの形成に新たな成形金型を製作する必要が無く、コストダウンが可能であるとともに、表示部ケースや表示パネルの形成を樹脂により形成することができ、デザインの統一性を保持して機種としての商品価値を高めることができる電子機器を得ることを目的とする。   The present invention has been made to solve the above-described problems, and by providing versatility to the display unit case and the display panel, a new molding die is used for forming the display unit case and the display panel. There is no need to manufacture, the cost can be reduced, and the display case and display panel can be made of resin, maintaining the uniformity of the design and increasing the product value as a model. The purpose is to obtain equipment.

この発明の請求項に係る電子機器は、ケースの内部に電子機器本体部が収納されるとともに、ケースの内部に発光素子が前面側に実装されたプリント板が収納された電子機器において、ケースにおける各発光素子の前面側に設けられ、発光表示部全体に対応した開口部を有する表示部ケースと、透明材からなり、表示部ケースの前面側に設けられた表示パネルと、表示部ケースと表示パネルとの間に設けられ、各発光素子の位置に合わせて開孔部を有する遮光板と、表示部ケースと遮光板との間に設けられ、各発光素子の位置に合わせて開孔部を有し、開孔部以外の箇所で、発光素子の光を遮断する導光用の板とから構成された発光表示部を備えたものである。 Electronic device according to claim 1 of the present invention, along with the electronic device main body is housed inside the case, an electronic apparatus emitting element printed circuit board mounted on the front side is accommodated inside the case, the case A display unit case provided on the front side of each light emitting element and having an opening corresponding to the entire light emitting display unit, a display panel made of a transparent material, provided on the front side of the display unit case, and a display unit case, A light-shielding plate provided between the display panel and having an aperture in accordance with the position of each light-emitting element, and provided between the display unit case and the light-shielding plate and in accordance with the position of each light-emitting element. have a, in portions other than the opening portion, in which a light-emitting display unit which is composed of a plate for guiding light for blocking light of the light emitting element.

以上のようにこの発明の請求項1によれば、表示部ケースと表示パネルとの間に各発光素子の位置に合わせて開孔部を有する遮光板を設けたので、発光素子の位置が変更になった場合には簡易抜型で容易に製作できる遮光板を変更するだけでよく、表示部ケースや表示パネルに汎用性を持たせることができ、新たな成形金型の製造を不要とすることができ、コストダウンが可能となる。このため、発光表示部の形成が容易となり、生産量が少ない異種プリント板を内蔵する電子機器の生産が容易となる。又、新たな成形金型が不要であるので、表示部ケースや表示パネルをすべて樹脂により形成することができ、デザインの統一性を保持し、商品価値を高めることができる。
特に、遮光板と、導光用の板の併用により発光表示部の視認性を高めることができる。
As described above, according to the first aspect of the present invention, the position of the light emitting element is changed because the light shielding plate having the apertures is provided between the display case and the display panel in accordance with the position of each light emitting element. In this case, it is only necessary to change the shading plate that can be easily manufactured by simple die cutting, and the display case and display panel can be made versatile, making it unnecessary to manufacture a new mold. And cost reduction is possible. For this reason, it becomes easy to form a light-emitting display portion, and it becomes easy to produce an electronic device incorporating a different kind of printed board with a small production amount. In addition, since a new molding die is not required, the display unit case and the display panel can all be formed of resin, so that the design uniformity can be maintained and the commercial value can be increased.
In particular, the visibility of the light-emitting display portion can be enhanced by the combined use of a light shielding plate and a light guide plate.
