Description
ここで、上記文献に記載の画像形成装置では、外装カバーをヘルムホルツ吸音管とする一方で、外装カバーによって覆われる作像部の内部でシートが搬送される構成となっていた。しかし、この構成では、シートの搬送に伴ってシート搬送路で発生する振動放射音を十分に低減できないという課題があった。 Here, in the image forming apparatus described in the above document, the outer cover is a Helmholtz sound absorbing tube, while the sheet is conveyed inside an image forming unit covered by the outer cover. However, in this configuration, there is a problem that vibration radiated sound generated in the sheet conveyance path as the sheet is conveyed cannot be sufficiently reduced.
そこで、本発明は、このような現状に鑑みてなされたものであり、シート搬送路を搬送されるシートの振動放射音を低減することのできるシート搬送装置、画像読取装置及び画像形成装置を提供することを目的とするものである。 Accordingly, the present invention has been made in view of such a current situation, and provides a sheet conveying apparatus, an image reading apparatus, and an image forming apparatus capable of reducing vibration radiation sound of a sheet conveyed in a sheet conveying path. It is intended to do.
本発明は、シート搬送装置において、シートが通過するシート搬送路と、前記シート搬送路を通過するシートの振動による振動放射音を吸音する吸音手段と、を備え、前記吸音手段は、前記シート搬送路を構成し、搬送されるシートを案内すると共に、複数の孔が形成されたガイド部材と、前記ガイド部材のシートと当接する側と反対側に配置され、前記複数の孔とそれぞれ連通する複数の空間を有するベース部材と、を備えることを特徴とするものである。 The present invention provides a sheet conveying apparatus, comprising: a sheet conveying path through which a sheet passes; and a sound absorbing means for absorbing vibration radiation sound caused by vibration of the sheet passing through the sheet conveying path, wherein the sound absorbing means includes the sheet conveying path. A guide member that forms a path and guides a sheet to be conveyed, and a plurality of holes that are formed on a side opposite to the side of the guide member that abuts against the sheet and communicates with the plurality of holes. a base member having a space is characterized in that to obtain Bei a.
また本発明は、シート搬送装置において、シートが通過するシート搬送路と、前記シート搬送路を通過するシートの振動による振動放射音を吸音する吸音手段と、を備え、前記吸音手段は、前記シート搬送路を構成し、搬送されるシートを案内すると共に、複数の孔が形成されたガイド部材と、前記ガイド部材のシートと当接する側と反対側に配置され、前記複数の孔とそれぞれ連通する複数の空間を有し、前記複数の孔の前記複数の空間に対する開口面積と、前記複数の孔に連通した状態にある前記複数の空間の体積との少なくとも一方を変更するよう前記ガイド部材に沿って移動可能な変更手段と、を有することを特徴とするものである。 In the sheet conveying apparatus, the present invention further includes: a sheet conveying path through which the sheet passes; and a sound absorbing means for absorbing vibration radiation sound caused by vibration of the sheet passing through the sheet conveying path, wherein the sound absorbing means includes the sheet A conveyance path is configured to guide the conveyed sheet, and a guide member having a plurality of holes is disposed on a side opposite to the side of the guide member that contacts the sheet, and communicates with each of the plurality of holes. Along the guide member so as to change at least one of an opening area of the plurality of holes with respect to the plurality of spaces and a volume of the plurality of spaces in communication with the plurality of holes. And changing means movable.
本発明のように、ガイド部材に複数の孔を設けて吸音手段とすることにより、シート搬送路を搬送されるシートの振動放射音を効果的に低減することができる。
As in the present invention, by a sound absorbing means provided multiple holes in the guide member, it is possible to effectively reduce the vibration noise radiation sheet conveyed to the sheet conveying path.
