Description
この発明は、特に、複写機若しくはプリンタから排出された用紙が、順序通りになるように順番にトレイに積載する用紙積載装置に関する。 In particular, the present invention relates to a sheet stacking apparatus that stacks sheets discharged from a copying machine or a printer on a tray in order so as to be in order.
従来から複写機若しくはプリンタで記録に供された用紙は、プリンタ内から排出され、排出された記録紙はトレイなどを有する排紙収納機構に収納されるようになっている。 Conventionally, paper used for recording by a copying machine or a printer is discharged from the printer, and the discharged recording paper is stored in a paper discharge storage mechanism having a tray or the like.
このような排紙収納機構として例えば、プリンタから排出された用紙を載置するためのトレイに放出されるようになっているが、トレイあるいはトレイ上の収納済みの用紙の上面に当接した状態を維持し、滑り落ちることができない。 As such a paper discharge storage mechanism, for example, the paper discharged from the printer is discharged to the tray for placing it, but is in contact with the upper surface of the tray or the stored paper on the tray. Can't keep slipping down.
そのため、トレイもしくはトレイ上の収納済みの用紙の上面の位置である排紙収納位置を、プリンタから排出された用紙が当接した後にトレイもしくはトレイ上の収納済みの用紙の上面に沿って滑ることを可能とするために、トレイは排紙ローラに対して角度を直角から離れた鋭角にするような適当な高低差をもった位置に水平に固設されているものがある。 Therefore, the paper discharge storage position that is the position of the upper surface of the tray or the stored paper on the tray slides along the upper surface of the tray or the stored paper on the tray after the paper discharged from the printer abuts. In order to achieve this, some trays are horizontally fixed at a position having an appropriate height difference such that the angle with respect to the discharge roller is an acute angle away from a right angle.
しかし、排出された用紙の先端が、トレイあるいはトレイ上の収納済みの用紙の上面に沿って滑るようにするため、排紙ローラとトレイとの鉛直距離を小さくせざるを得ず、このため収納可能な用紙の枚数が制限され、多量の用紙を収納するのには好適ではないことから、トレイ上に収納された用紙の重さに比例して、トレイが、先端部近傍を支持されて回動可能となり、排紙収納位置を、排出された用紙が滑るようにし、多量の用紙を収納可能とするものがある（特許文献１）。 However, since the leading edge of the discharged paper slides along the tray or the upper surface of the stored paper on the tray, the vertical distance between the paper discharge roller and the tray has to be reduced. Since the number of sheets that can be used is limited and is not suitable for storing a large amount of sheets, the tray is supported by the vicinity of the front end in proportion to the weight of the sheets stored on the tray. There is one that can move and allows a large amount of paper to be accommodated by sliding the ejected paper at the paper discharge storage position (Patent Document 1).
このように、トレイ上に収納された用紙の重さに比例して、トレイが、先端部近傍を支持されて回動可能となるための機構が複雑であり、しかも確実に用紙の重さに比例して回動させることができないなどの問題がある。また、単一のトレイに積載するだけであり、多量の用紙を積載することが困難であり、しかも用紙のサイズに対応したトレイへの積載もできなかった。 Thus, in proportion to the weight of the paper stored on the tray, the mechanism for allowing the tray to rotate while being supported in the vicinity of the front end is complicated, and the weight of the paper is reliably ensured. There is a problem that it cannot be rotated proportionally. In addition, it is only possible to stack on a single tray, it is difficult to stack a large amount of sheets, and it is also impossible to stack on a tray corresponding to the size of the sheet.
この発明は、このような従来の構成が有していた問題を解決しようとするものであり、簡単な構造で、用紙のサイズに応じて多量の用紙の積載を可能とする用紙積載装置を提供することを目的とする。 The present invention is intended to solve the problems of such a conventional configuration, and provides a paper stacking device capable of stacking a large amount of paper according to the paper size with a simple structure.
