Description

本発明は、画像形成装置、装置外装カバー、用紙搬送ガイドに関する。   The present invention relates to an image forming apparatus, an apparatus exterior cover, and a sheet conveyance guide.

従来の電子写真方式の画像形成装置では、記録シート上のトナー像を加熱定着する際に、用紙が高温で加熱されるため、装置内に熱気が篭りやすくなる。この熱気は装置内の部材に悪影響を与えるため、速やかに熱気を画像形成装置外に排気する必要がある。   In a conventional electrophotographic image forming apparatus, when a toner image on a recording sheet is heated and fixed, the sheet is heated at a high temperature, so that hot air is easily generated in the apparatus. Since this hot air adversely affects members in the apparatus, it is necessary to quickly exhaust the hot air outside the image forming apparatus.

例えば、装置内で発生する水蒸気を含む排気を導くダクトを設け、排気を装置外に排出するための開口部を装置外装にダクトに連続して形成する画像形成装置がある(例えば、特許文献1参照。)。

以下、本発明に係る画像形成装置、装置外装カバー、用紙搬送ガイドの実施の形態について添付図面を参照して詳細に説明する。   Hereinafter, embodiments of an image forming apparatus, an apparatus exterior cover, and a sheet conveyance guide according to the present invention will be described in detail with reference to the accompanying drawings.

図1は、本発明に係る画像形成装置1の断面図の一例である。   FIG. 1 is an example of a cross-sectional view of an image forming apparatus 1 according to the present invention.

図1に示すように、画像形成ユニット2の上方部に位置する開閉可能(図に示す矢印方向に開閉が可能)な外装カバー3に排気ファン4を設け、更に、外装カバー3に画像形成ユニット2で画像形成を施された用紙を用紙搬送路5に沿って案内するための用紙搬送ガイド6を複数設けている。   As shown in FIG. 1, an exhaust fan 4 is provided in an exterior cover 3 that can be opened and closed (can be opened and closed in the direction of the arrow shown in the figure) located above the image forming unit 2. A plurality of sheet conveyance guides 6 are provided for guiding the sheet on which the image is formed in 2 along the sheet conveyance path 5.

図2は、用紙搬送ガイド6の斜視図の一例である。   FIG. 2 is an example of a perspective view of the paper transport guide 6.

なお、図4に示す一番右側の用紙搬送ガイド6だけを排気ファン4の近くまで伸ばす形状とすることで、排気ダクトの機能を更に高めることが可能になり、排気ファン4への気流の集中が更に効率良くなる。   It is possible to further enhance the function of the exhaust duct by concentrating only the rightmost sheet conveyance guide 6 shown in FIG. Becomes more efficient.

従って、図5に示すように、画像形成ユニット2から発生して装置内の上部に上昇した熱気は、用紙搬送ガイド6によって効率良く排気ファン4に集中し、装置内の熱気の排気が効率良く行われることになる。   Therefore, as shown in FIG. 5, the hot air generated from the image forming unit 2 and rising to the upper part in the apparatus is efficiently concentrated on the exhaust fan 4 by the sheet conveyance guide 6, and the hot air in the apparatus is efficiently exhausted. Will be done.

なお、用紙搬送ガイド6の形状を変形させることで、用紙搬送ガイド6に排気ダクトの機能を兼ねさせる上述の一例に限定することなく、用紙の搬送路5が外装カバー3の近くに設けられていない場合は、外装カバー3の内側表面に排気ファンの位置に向けて湾曲させたまたは折り曲がった凹溝等を設けることで、外装カバー3自体に排気ダクトの機能を兼ねさせる構成でも適用可能である。   In addition, by changing the shape of the paper conveyance guide 6, the paper conveyance path 5 is provided near the exterior cover 3 without being limited to the above example in which the paper conveyance guide 6 also functions as an exhaust duct. If not, a configuration in which the outer cover 3 itself also serves as an exhaust duct can be applied by providing a concave groove or the like curved or bent toward the position of the exhaust fan on the inner surface of the outer cover 3. is there.

本発明に係る画像形成装置の断面図の一例である。1 is an example of a cross-sectional view of an image forming apparatus according to the present invention. 用紙搬送ガイドの斜視図の一例である。FIG. 3 is an example of a perspective view of a paper transport guide. 外装カバーを開いた状態の画像形成装置の断面図の一例である。1 is an example of a cross-sectional view of an image forming apparatus with an exterior cover open. 外装カバーを図3中のA−B線に見た平面図の一例である。It is an example of the top view which looked at the exterior cover at the AB line in FIG. 画像形成装置内における熱気の排気処理の一例を示す図である。FIG. 4 is a diagram illustrating an example of hot air exhaust processing in the image forming apparatus.
