Description
本発明は、外装部材、電子機器及び画像形成装置に係り、特に外装板部に複数個所の中空部を備える外装部材、電子機器及び画像形成装置に関する。 The present invention relates to an exterior member, an electronic device, and an image forming apparatus, and more particularly, to an exterior member, an electronic device, and an image forming apparatus that include a plurality of hollow portions in an exterior plate portion.
電子機器である画像形成装置例えば電子写真装置の外装には、一方向に開閉する開閉扉が使用されることがあり、該扉を開放してメンテナンスや消耗品の補給等を行う。このような電子写真装置の開閉扉にあっては、安全上及び操作性から相当の強度が必要で、大型機の開閉扉は合成樹脂を型成形する際、リブを形成したり、コアバック成型、ブロー成型などで中空部を設け強度を確保している。 An opening / closing door that opens and closes in one direction may be used for an exterior of an image forming apparatus, for example, an electrophotographic apparatus, which is an electronic device. The door is opened to perform maintenance, supply of consumables, and the like. The doors of such an electrophotographic apparatus require considerable strength for safety and operability, and the doors of large machines are formed with ribs or core back molding when molding synthetic resin. A hollow part is provided by blow molding or the like to ensure strength.
このような画像形成装置の開閉扉に関して特許文献１の図２ないし図４に開示がある。
しかし、近来電子機器のデザインが多様化し、形状が複雑となり、開閉扉などの外装材に溝やくぼみが形作られてきており、コアバック形成などは一体で作ることが困難になってきた。すなわち、コアバック形成における製品の冷却時に、製品にへこみが生じてしまうため、強度・外観上好ましくないことになるからである。 However, the design of electronic devices has recently become diversified, the shape has become complicated, and grooves and indentations have been formed in exterior materials such as doors, making it difficult to form core backs and the like. That is, when the product is cooled in the core back formation, a dent is generated in the product, which is not preferable in terms of strength and appearance.
本発明は、複数の中空部を備えた外装部材を良好な強度・外観で製造することができる外装部材、電子機器及び画像形成装置を提供することを目的とする。 It is an object of the present invention to provide an exterior member, an electronic device, and an image forming apparatus that can manufacture an exterior member having a plurality of hollow portions with good strength and appearance.
請求項１の発明は、合成樹脂で成型され外装板部に複数個所の中空部を備えるとともに前記外装板に前記中空部を接続するリブを形成したことを特徴とする外装部材である。 The invention according to claim 1 is an exterior member that is formed of a synthetic resin and includes a plurality of hollow portions in the exterior plate portion and ribs that connect the hollow portions to the exterior plate.
請求項２の発明は、請求項１の外装部材において、前記リブの高さを前記中空部より低く形成したことを特徴とする。 According to a second aspect of the present invention, in the exterior member of the first aspect, the height of the rib is lower than that of the hollow portion.
請求項３の発明は、請求項１または２の外装部材において、前記中空部をコアバック方式で形成することを特徴とする。 According to a third aspect of the present invention, in the exterior member of the first or second aspect, the hollow portion is formed by a core back method.
請求項４の発明は、請求項１ないし３のいずれかの外装部材において、外装部材は電子機器の外装に使用することを特徴とする。 According to a fourth aspect of the present invention, in the exterior member according to any one of the first to third aspects, the exterior member is used for an exterior of an electronic device.
請求項５の発明は、請求項４の外装部材において、外装部材は、画像形成装置の開閉蓋であることを特徴とする。 According to a fifth aspect of the invention, in the exterior member of the fourth aspect, the exterior member is an open / close lid of the image forming apparatus.
請求項６の発明は、電子機器において、請求項１ないし５のいずれかの外装部材を備えたことを特徴とする。 According to a sixth aspect of the present invention, in the electronic apparatus, the exterior member according to any one of the first to fifth aspects is provided.
請求項７の発明は、電子機器において、請求項６の外装部材を開閉扉として使用したことを特徴とする。 According to a seventh aspect of the present invention, in the electronic apparatus, the exterior member of the sixth aspect is used as an opening / closing door.
請求項８の発明は、画像形成装置において、請求項１ないし５のいずれかの外装部材を備えたことを特徴とする。 According to an eighth aspect of the present invention, in the image forming apparatus, the exterior member according to any one of the first to fifth aspects is provided.
請求項９の発明は、外装部材を開閉扉として使用したことを特徴とする請求項８の画像形成装置である。 The invention according to claim 9 is the image forming apparatus according to claim 8, wherein the exterior member is used as an opening / closing door.
本発明に係る中空部間にリブを形成したので、複数の中空部を備えた外装部材を良好な強度・外観で製造することができるという効果がある。 Since the ribs are formed between the hollow portions according to the present invention, there is an effect that an exterior member having a plurality of hollow portions can be manufactured with good strength and appearance.
以下本発明を実施するための最良の形態としての実施例を図面を参照して説明する。 Embodiments as the best mode for carrying out the present invention will be described below with reference to the drawings.
図１は本発明の実施例に係る画像形成装置の全体の構成を示す図、図２は本発明の実施例に係る画像形成装置の正面開閉扉の内側を示す斜視図、図３は本発明の実施例に係る画像形成装置の正面扉の内側を示す平面図、図４は本発明の実施例に係る画像形成装置の正面扉の内側を示す拡大図である。 FIG. 1 is a diagram showing the overall configuration of an image forming apparatus according to an embodiment of the present invention, FIG. 2 is a perspective view showing the inside of a front opening / closing door of the image forming apparatus according to an embodiment of the present invention, and FIG. FIG. 4 is an enlarged view showing the inside of the front door of the image forming apparatus according to the embodiment of the present invention.
本例において、外装部材は、図１に示すように、画像形成装置２０の正面開閉扉１０に適用される。ここで、画像形成装置２０は、自動原稿移送装置２１、画像形成装置本体２２を備える。正面開閉扉１０を開け、画像形成装置２０に内蔵された画像形成ユニット、転写ユニット、定着ユニット、用紙搬送装置などが現れる。 In this example, the exterior member is applied to the front door 10 of the image forming apparatus 20 as shown in FIG. Here, the image forming apparatus 20 includes an automatic document feeder 21 and an image forming apparatus main body 22. The front opening / closing door 10 is opened, and an image forming unit, a transfer unit, a fixing unit, a sheet conveying device, and the like built in the image forming apparatus 20 appear.
本例では、正面開閉扉１０は合成樹脂で公知のコアバック方式で成型される。また、本例では、正面開閉扉１０は、外装板部材１１と、左右の立設部１２，１３と、湾曲形成部１４と垂下部１５とから構成される。また外装板部材１１には上下方向に溝部１６が形成されている。 In this example, the front opening / closing door 10 is formed of synthetic resin by a known core back method. In this example, the front opening / closing door 10 includes an exterior plate member 11, left and right standing portions 12 and 13, a curve forming portion 14, and a hanging portion 15. Further, a groove 16 is formed in the exterior plate member 11 in the vertical direction.
また、本例では、溝部１６の両側に中空部１及び中空部２が形成され補強が施されている。また、本例では、中空部１と中空部２とは９本のリブ３が形成されている。このリブ３は外装板部材１１及び湾曲形成部１４から立設形成され両中空部１，２を接続している。 Moreover, in this example, the hollow part 1 and the hollow part 2 are formed in the both sides of the groove part 16, and are reinforced. In this example, the hollow portion 1 and the hollow portion 2 are formed with nine ribs 3. The rib 3 is erected from the exterior plate member 11 and the curve forming portion 14 and connects the hollow portions 1 and 2.
さらに、本例では図３に示すように、前記リブ３は、中空部１，２より低くなっている（図４中３ａで示した）。 Furthermore, in this example, as shown in FIG. 3, the rib 3 is lower than the hollow portions 1 and 2 (indicated by 3a in FIG. 4).
従って本例によれば、独立した中空部のままでは、開閉扉全体の歪み、撓みを押さえることができず、コアバックの間に応力が集中してしまい、破損しやすくなったのに対して、リブで補強ができ正面開閉扉の強度を補うことができる。 Therefore, according to this example, if the independent hollow portion remains, the distortion and deflection of the entire open / close door cannot be suppressed, and stress is concentrated between the core backs, which is easily damaged. The rib can be reinforced and the strength of the front door can be supplemented.
また、本例ではリブを中空部より低く形成し、型の作成費を抑えるえることができる。 Further, in this example, the rib can be formed lower than the hollow portion, and the production cost of the mold can be suppressed.
なお、上記例では、電子機器として画像形成装置を例として説明したが、他の電子機器の外装部材として使用することができる。 In the above example, the image forming apparatus has been described as an example of the electronic apparatus. However, the image forming apparatus can be used as an exterior member of another electronic apparatus.
