Description
本発明は、複写機、プリンタ、ファクシミリ、又は、それらの複合機等の画像形成装置やその周辺機器等の機器に設けられるＬＥＤ発光レンズなどを用いた発光部構造に関し、詳細には、操作者のどの立ち位置からでも視認しやすくしたものに関する。 The present invention relates to a light emitting unit structure using an LED light emitting lens or the like provided in an image forming apparatus such as a copying machine, a printer, a facsimile, or a complex machine thereof, or a device such as a peripheral device thereof. It relates to things that are easy to see from any standing position.
図１は、画像形成システムの一例を示す外観図であり、図の中央に位置する画像形成ユニット１に、大量給紙ユニット２と排紙ユニット３を組み合わせて構成してある。画像形成ユニット１は、図示は省略するが画像形成を行う作像部を内蔵し、外部には、上面の排紙ユニット３寄りの位置に自動原稿給紙装置（ＡＤＦ）４を設け、その右側の大量給紙ユニット２側にトナーボトル収納部５を備えている。また、トナーボトル収納部５の天井面上部には操作用ディスプレイ６がアーム７を介して角度可変に設けてある。画像形成ユニット１の下部には給紙部８を備えている。 FIG. 1 is an external view showing an example of an image forming system. The image forming unit 1 located in the center of the figure is combined with a large-volume paper feeding unit 2 and a paper discharging unit 3. Although not shown, the image forming unit 1 has a built-in image forming unit for forming an image, and an external document feeder (ADF) 4 is provided on the outside at a position near the paper discharge unit 3 on the right side. The toner bottle storage unit 5 is provided on the large-volume paper supply unit 2 side. Further, an operation display 6 is provided at an upper portion of the ceiling surface of the toner bottle storage unit 5 via an arm 7 so that the angle can be changed. A paper feed unit 8 is provided below the image forming unit 1.
このような画像形成システムでは、上述した各種の機器がドアの開閉や、給紙トレイの出し入れ等の操作を伴うので、カバーの開閉やトレイの操作を楽にするため、操作用のレバーを備えているが、その近傍には、カバーやトレイが存在することを操作者に視認させるための発光部が設けられている。 In such an image forming system, since the various devices described above involve operations such as opening and closing the door and loading and unloading the paper feed tray, an operation lever is provided to facilitate the opening and closing of the cover and the operation of the tray. However, in the vicinity thereof, a light emitting unit is provided for allowing the operator to visually recognize the presence of the cover and the tray.
例えば給紙トレイ９の操作は、給紙部８から給紙トレイ９を引き出し、あるいは給紙部８押し込む操作となるが、操作部位である給紙トレイ９を示すため、各給紙トレイ９の外装面に設けた発光部２０のうち、操作対象となる発光部２０を発行させるなどしている。あるいは、操作対象となる給紙トレイ９の位置に応じた発光は行わせなくても、図示せぬが給紙段の名称を近傍に記載するなどして操作者が視認しやすくしてある。 For example, the operation of the paper feed tray 9 is an operation of pulling out the paper feed tray 9 from the paper feed unit 8 or pushing in the paper feed unit 8. Among the light emitting units 20 provided on the exterior surface, the light emitting unit 20 to be operated is issued. Alternatively, even if the light emission according to the position of the paper feed tray 9 to be operated is not performed, the name of the paper feed stage is not shown, but it is easy for the operator to visually recognize.
なお図中１４は画像形成ユニット１の前ドア、１５はその取手１５、１６は大量給紙ユニット２の給紙段、１７はその操作用の取手１７、１８は排紙ユニット３の前ドア、１９はその取手１９である。図示の例では、大量給紙ユニット２の給紙段（図の例では３段）にそれぞれ発光部２０が設けてある。 In the figure, 14 is the front door of the image forming unit 1, 15 is the handle 15, 16 is the paper feed stage of the large-volume paper feed unit 2, 17 is the handle 17 for operation, 18 is the front door of the paper discharge unit 3, Reference numeral 19 denotes the handle 19. In the example shown in the figure, the light emitting units 20 are provided in the paper feed stages (three stages in the example) of the large-volume paper feed unit 2, respectively.
ところでこのような画像形成装置において、給紙部８などを含む保守補給操作を誘導するための状態表示を行うにはＬＥＤを利用した発光部を用いることが多くなってきているが、ＬＥＤを利用した発光体は取り付ける面とＬＥＤの発光面を同一面あるいは略同一面とすることができ、省スペースに貢献し得るものであるが、そのような構成とした場合、画像形成装置の左右問わず斜め方向からの視認も困難になる。 By the way, in such an image forming apparatus, in order to display a status for guiding a maintenance and replenishment operation including the paper feeding unit 8 and the like, a light emitting unit using an LED is often used. The light-emitting body can be mounted on the same surface or substantially the same light-emitting surface of the LED, and can contribute to space saving. Viewing from an oblique direction is also difficult.
また、ＬＥＤを利用した発光体をレンズごと出っ張らせて設けた場合、ユーザーがその設置箇所の近傍を通過する際に、例えば手の甲が当たって怪我をしたり、外部からの衝撃によって発光部、発光体が凹んだり、傷付いたり、破損したりする等の事態が懸念される。 In addition, when a light-emitting body using an LED is provided so as to protrude with the lens, when the user passes near the installation location, for example, the back of the hand hits him or gets injured, or an external impact causes the light-emitting part to emit light. There are concerns that the body will be dented, scratched, or damaged.
また、ＬＥＤを利用した発光体の発光面を上向き、もしくは下向きのいずれかに限定して装備した場合、視認できる範囲も限定されてしまう。発光面をルーレット加工にすることによりある程度の輝度を得ることは可能であるが、成形上の制約条件により、充分な輝度を得られるというレベルまでに上げることは多大な作業時間、コストを要する場合がある。 Further, when the light emitting surface of the light emitting body using the LED is limited to either upward or downward, the visible range is also limited. It is possible to obtain a certain level of brightness by making the light emitting surface roulette processed, but if it takes a lot of work time and cost to raise it to a level where sufficient brightness can be obtained due to molding restrictions There is.
すなわち、取り付け面とＬＥＤ発光面が同一面にある場合、画像形成装置の左右だけでなく斜め方向からの視認が困難であること、また、そのままレンズごと出っ張らせた場合、ユーザーが画像形成装置の近傍を通過する人に当たるなどして怪我をさせる心配があること、また外部からの衝撃によって破損すること等の事態が懸念される。 That is, when the mounting surface and the LED light emitting surface are on the same surface, it is difficult to see the image forming apparatus not only from the right and left sides but also from an oblique direction. There is a concern that there may be a risk of injury by hitting a person passing through the vicinity, or damage due to an external impact.
そこで本発明においては、角度が異なる２つの面で構成された形状とすることにより、画像形成装置の前におけるどの立ち位置からでも視認が容易で、低コスト化が図れる発光部構造と、これを用いた画像形成装置を提供することを目的とする。 Therefore, in the present invention, a light-emitting unit structure that can be easily viewed from any standing position in front of the image forming apparatus and reduced in cost by adopting a shape constituted by two surfaces with different angles, and this is provided. An object of the present invention is to provide an image forming apparatus used.

本発明に係る発光部構造は、発光部を、画像形成装置の前におけるどの立ち位置からでも容易に視認できるという効果がある。また、レンズ表面の下側の面を斜め下方へ向いた発光面とすることにより、下側のレンズ面は下端に向かうほど機器の外装面に近づくので、下側のレンズ面が単に鉛直方向に平行な向きよりも、機器の外装面の裏側に配置された発光体と下側のレンズ面との間の距離は近くなる。つまり、下側のレンズ面を、鉛直方向に平行な向きの発光面とするよりも、斜め下方へ向いた発光面とするほうが、下側のレンズ面からの光の射出量が多くなるので、発光部全体としてより明るく視認することができる。
The light emitting unit structure according to the present invention has an effect that the light emitting unit can be easily visually recognized from any standing position in front of the image forming apparatus. In addition, by making the lower surface of the lens surface a light emitting surface that faces obliquely downward, the lower lens surface approaches the exterior surface of the device toward the lower end, so the lower lens surface is simply in the vertical direction. The distance between the light emitter disposed on the back side of the exterior surface of the device and the lower lens surface is closer than the parallel orientation. In other words, the amount of light emitted from the lower lens surface is larger when the lower lens surface is a light emitting surface directed obliquely downward than the light emitting surface oriented in the vertical direction. The entire light emitting unit can be visually recognized more brightly.
発光部が備えるレンズを、出っ張らせかつ両端をあまり大きくは突出させないようＲ面で処理した形状を有し、また、発光体の発光面を上向き、もしくは下向きいずれかに限定した場合、視認できる範囲も限定されてしまうという課題を解決するために、角度が異なる２つの面で構成したレンズカバー形状を有するレンズ部を備えることで、ハウジング外または可能な限りハウジング側端部に近い位置からイメージを入力するという手段をとり、これを、最小の部品点数で、光学系構成部品の厚みを損なわずに実現した。 Range that can be visually recognized when the lens provided in the light emitting part has a shape processed by an R surface so that it protrudes and both ends do not protrude too much, and the light emitting surface of the light emitter is limited to either upward or downward In order to solve the problem of being limited, an image can be obtained from a position outside the housing or as close to the end on the side of the housing as possible by providing a lens portion having a lens cover shape composed of two surfaces with different angles. By taking the means of input, this was achieved with the minimum number of parts and without sacrificing the thickness of the optical system components.
＜実施例１＞
以下本発明に係る実施例を図面を参照して説明する。なお以下では、図１に示した画像形成システムをなす画像形成ユニット１の給紙部８に設けたＬＥＤを用いた発光部２０の構造についてのみ説明するが、その他の部位の発光部についても同じ構造を採用することができ、また本発明は図示の具体的な構造には限定されず、本発明の概念、趣旨に基づいて種々変形例を想到可能であることは言うまでもない。すなわち、発光体もＬＥＤに限定されるものではない。また符号は図１と共通する部分には同一の符号を付して説明する。
<Example 1>
Embodiments according to the present invention will be described below with reference to the drawings. Hereinafter, only the structure of the light emitting unit 20 using the LED provided in the paper feeding unit 8 of the image forming unit 1 constituting the image forming system shown in FIG. 1 will be described, but the same applies to the light emitting units of other parts. Needless to say, the present invention is not limited to the illustrated specific structure, and various modifications can be conceived based on the concept and spirit of the present invention. That is, the light emitter is not limited to the LED. Further, the same reference numerals are given to the portions common to FIG.
まず、画像形成ユニット１の給紙部８の外面と発光部２０の外面（具体的には後述するが、レンズの外面となる。）がいわゆる面一状態にある場合、画像形成ユニット１の左右問わず斜め方向からでも視認は困難になる。しかし、そのままレンズごと出っ張らせた場合、ユーザーが近傍を通過する際に手の甲がレンズに接触、当接して怪我をしたり、外部からのレンズへの衝撃による凹み、傷、破損などの事態が懸念される。発光部２０の発光面を上向き、もしくは下向きのいずれかに限定した場合、やはり視認できる範囲が限定されてしまう。 First, when the outer surface of the paper feeding unit 8 of the image forming unit 1 and the outer surface of the light emitting unit 20 (specifically, the outer surface of the lens, which will be described later) are in a so-called flush state, Regardless of the direction, it is difficult to see even from an oblique direction. However, if the entire lens is projected as it is, the back of the hand may come into contact with or contact the lens when the user passes nearby, causing injuries, or dents, scratches, or damage due to external impact on the lens. Is done. When the light emitting surface of the light emitting unit 20 is limited to either upward or downward, the visible range is also limited.
図２は、本発明の実施例１に係る発光部２０の外観を示す斜視図（Ａ）と正面図（Ｂ）である。また図３は、図２に示した発光部２０を画像形成ユニット１の給紙部８に取り付けた状態の平面図（Ａ）と側面図（Ｂ）である。 FIG. 2 is a perspective view (A) and a front view (B) showing an appearance of the light emitting unit 20 according to the first embodiment of the present invention. FIG. 3 is a plan view (A) and a side view (B) of the light emitting unit 20 shown in FIG. 2 attached to the paper feed unit 8 of the image forming unit 1.
本実施形態の発光部２０のレンズ２１は、画像形成ユニット１の給紙部８の表面から出っ張らせ、かつ左右方向では両端をあまり大きくは突出させないようＲ面２２を形成して処理した形状としてある。そして、Ｒ面２２を設けることにより、例えば図４に示すように、ユーザー２５、３０が画像形成ユニット１にかなり近付いた立ち位置からでも、またその立ち位置が正面でなくて左右いずれかに寄っていても容易に視認できるようになる。そのため、ユーザー２５が近傍を通過する際、手の甲などを当てて怪我するなどの事態を回避できるだけでなく、画像形成ユニット１の装置本体の外観を損なわないデザイン性を発揮できる。 The lens 21 of the light emitting unit 20 of the present embodiment has a shape that is processed by forming an R surface 22 so as to protrude from the surface of the paper feeding unit 8 of the image forming unit 1 and not project both ends too much in the left-right direction. is there. By providing the R surface 22, for example, as shown in FIG. 4, even when the users 25 and 30 are standing close to the image forming unit 1, the standing positions are not on the front but on either the left or right side. Even if it is, it will be easily visible. For this reason, when the user 25 passes the vicinity, not only can the user 25 be injured by hitting the back of the hand, but also the design that does not impair the appearance of the main body of the image forming unit 1 can be exhibited.
本実施例の発光部２０のレンズ２１は、図２（Ｂ）に示した水平な線Ｘを境に、その上下で角度が異なる２つの面にすることにより、図３（Ｂ）に示すように、ユーザー２５の通常の立ち位置から確認できる視線高さ（Ａ）からは上向きの発光面２１ａが視認できる。画像形成ユニット１の比較的低い位置にある給紙トレイ９に設けても同様である。さらに、ユーザーが遠方にいるときや、しゃがんだ状態、または車イスユーザーのような低い視線高さ（Ｂ）からは、やや下向きの発光面２１ｂで発光部２０を視認できるようになる。また、現状の成型技術、低コストで容易に量産が可能である。さらに、レンズ表面の下側の面（以下、「下側のレンズ面」）を斜め下方へ向いた発光面（下向きの発光面２１ｂ）とすることにより、下側のレンズ面は下端に向かうほど機器の外装面に近づくので、下側のレンズ面が単に鉛直方向に平行な向きとするよりも、機器の外装面の裏側に配置された発光体と下側のレンズ面との間の距離は近くなる。つまり、下側のレンズ面を鉛直方向に平行な向きの発光面とするよりも、斜め下方へ向いた発光面とするほうが、下側のレンズ面からの光の射出量が多くなるので、発光部全体としてより明るいと視認できるようになる。
As shown in FIG. 3B, the lens 21 of the light emitting unit 20 according to the present embodiment has two surfaces with different angles at the top and bottom of the horizontal line X shown in FIG. 2B. In addition, the upward light emitting surface 21a can be seen from the line-of-sight height (A) that can be confirmed from the normal standing position of the user 25. The same applies to the paper feed tray 9 provided at a relatively low position of the image forming unit 1. Further, when the user is far away, in a squatting state, or from a low line-of-sight height (B) like a wheelchair user, the light emitting unit 20 can be visually recognized with the light emitting surface 21b facing slightly downward. Moreover, mass production can be easily performed with the current molding technology and low cost. Furthermore, by setting the lower surface of the lens surface (hereinafter referred to as “lower lens surface”) as a light emitting surface (downward light emitting surface 21 b) that faces obliquely downward, the lower lens surface becomes closer to the lower end. Since it approaches the exterior surface of the device, the distance between the illuminant placed on the back side of the exterior surface of the device and the lower lens surface is less than the lower lens surface simply oriented parallel to the vertical direction. Get closer. In other words, the amount of light emitted from the lower lens surface is larger when the lower lens surface is a light emitting surface that faces obliquely downward than the light emitting surface that is parallel to the vertical direction. If the whole part is brighter, it will be visible.
なお、図示の例では上側の発光面、すなわち上向きの発光面２１ａのほうを、下側の発光面、すなわち下向きの発光面２１ｂよりも面積を大きくしているが、これは上方からの視認性を考慮したものである。ただし、本発明ではこれを逆にして下側のほうが面積が大きい構造としてもよい。 In the illustrated example, the area of the upper light emitting surface, that is, the upward light emitting surface 21a is larger than that of the lower light emitting surface, that is, the downward light emitting surface 21b. Is taken into account. However, in the present invention, this may be reversed and the lower area may have a larger area.
さらに、図３（Ａ）に示すように、平面形状としても発光部２０のレンズ２１の左右方向両端を薄く形成し、ユーザー２５が近傍を通過する際に引っ掛かりにくくしてある。 Furthermore, as shown in FIG. 3 (A), both ends in the left-right direction of the lens 21 of the light emitting unit 20 are thinly formed so as to have a planar shape so that the user 25 is not easily caught when passing the vicinity.
＜実施例２＞
