Description

本発明は、複写機、レーザービームプリンター等の画像形成装置の後段に接続される排紙装置に関するものである。   The present invention relates to a paper discharge device connected to a subsequent stage of an image forming apparatus such as a copying machine or a laser beam printer.

図４に排紙装置の一例を示す。排紙装置６は、画像形成装置（図示せず）の後段に設けられ、画像形成装置から出力される印刷済用紙を揃えて積み重ねていくものである。この排紙装置６は製本や仕分けなどの後処理を考慮し、印刷済用紙のサイズ毎に複数のスタックトレイに排出され、図３のようにスタックトレイにそれぞれ設けられたドロア２上の用紙積載箱５（以下用紙バスケットと呼ぶ）の中に配されている用紙積載テーブル上に積み重ねられる。このドロア２及び用紙バスケット５は通常、スタックトレイ毎にそれぞれカバーに覆われ、必要に応じてカバーを開閉することによりドロア２を引き出し用紙バスケット５内の用紙を取り出す構成の場合や、またカバー無しの構成で直接ドロア２を引き出し、用紙バスケット５内の用紙を取り出す構成が取られている。   FIG. 4 shows an example of a paper discharge device. The paper discharge device 6 is provided at a subsequent stage of the image forming apparatus (not shown), and is configured to stack printed sheets output from the image forming apparatus in a uniform manner. In consideration of post-processing such as bookbinding and sorting, the paper discharge device 6 is discharged to a plurality of stack trays for each size of printed paper, and the paper stacking on the drawer 2 provided on each stack tray as shown in FIG. The sheets are stacked on a sheet loading table arranged in a box 5 (hereinafter referred to as a sheet basket). The drawer 2 and the paper basket 5 are usually covered with a cover for each stack tray, and the drawer 2 is pulled out by opening and closing the cover as needed to take out the paper in the paper basket 5 or no cover. In this configuration, the drawer 2 is directly pulled out and the paper in the paper basket 5 is taken out.

しかしながら、前記のような特にスタックトレイにカバー無しの構成の際には用紙バスケットが用紙サイズ（ショートサイズやロングサイズ）に分けて採用されることが無く、一種類の用紙バスケットで全ての用紙サイズに対応させる必要があるため、必然的に画像形成装置の性能最大の用紙サイズに合わせた大きい用紙バスケット（以下、ラージバスケットと称す）のみの構成であった。   However, the paper baskets are not divided into paper sizes (short size and long size), especially when the stack tray is not covered as described above, and one type of paper basket can handle all paper sizes. Therefore, the configuration is inevitably only a large paper basket (hereinafter referred to as a large basket) that matches the maximum paper size of the image forming apparatus.

さらに、ショートサイズ用紙に合わせた小さい用紙バスケット（以下、スモールバスケットと称す）を採用しようとしても、スタックトレイにカバー無しのオープン状態のために、単にスモールバスケットをセットしたのみではラージバスケットとの大きさの違いによりテーブル昇降部が剥き出しになるため、その安全性を確保するためにはダミーの箱とその検出手段等の目隠しを設ける必要がある。   In addition, even if you try to adopt a small paper basket (hereinafter referred to as a small basket) that matches short-size paper, the size of the large basket is simply the size of the small basket because it is open without a cover on the stack tray. Since the table elevating part is exposed due to the difference, it is necessary to provide a dummy box and its detection means blindfold in order to ensure its safety.

しかしながら、前記のような手段においては、画像形成装置で印刷される用紙サイズが変わり、排紙装置のスタックトレイ内の用紙バスケットを取替える場合にオペレーターの操作が煩雑になることになる。   However, in the above-described means, the paper size printed by the image forming apparatus changes, and the operator's operation becomes complicated when the paper basket in the stack tray of the paper discharge device is replaced.

本発明は、画像形成装置から排出される印刷済用紙を、印刷済用紙のサイズ毎に積み重ねる排紙装置であって、用紙積載テーブルである底面及び用紙を保持する側面よりなり、印刷済用紙を収容、運搬するため着脱可能に設けられた用紙積載箱と、出力する用紙のサイズに応じた用紙積載箱を搭載するべく、該用紙積載箱を前記排紙装置より出し入れするためのドロアを備え、該ドロアの引き出し方向前側に、該ドロアの引き出し方向と直交する方向に延在する仕切り板を回転収容可能に設け、前記画像形成装置の印刷性能の最大長さの用紙サイズよりも用紙長さの短い用紙サイズを収納する用紙積載箱を使用する際には前記仕切り板を前記ドロアとのなす角が略９０度となるようにセットすることを特徴とする。
The present invention relates to a paper discharge device that stacks printed paper discharged from an image forming apparatus for each size of printed paper, and includes a bottom surface that is a paper stacking table and a side surface that holds the paper. A paper stacking box detachably provided for storing and transporting, and a drawer for loading and unloading the paper stacking box from the paper discharge device in order to mount a paper stacking box corresponding to the size of the output paper, A partition plate extending in a direction perpendicular to the drawer pull-out direction is provided on the front side of the drawer pull-out direction so as to be capable of rotating accommodation, and has a sheet length that is larger than the maximum sheet size of the printing performance of the image forming apparatus. When a paper stacking box that stores a short paper size is used, the partition plate is set so that an angle formed by the drawer is approximately 90 degrees .

本発明によれば、排紙装置の用紙サイズによる用紙バスケットの交換の際の煩雑さを防止でき、且つ安全性を確保できる。   According to the present invention, it is possible to prevent complications when replacing the paper basket depending on the paper size of the paper discharge device, and to ensure safety.

相違なバスケット交換時のオペレーターの煩雑さの軽減と、ショートバスケットセット時の安全性の確保という目的を、ドロアに回転収納可能なしきり板にて実現した。以下本発明を実施例図面によって説明する。   The purpose of reducing the complexity of the operator when changing the basket and ensuring the safety when setting the short basket has been realized with a squeeze plate that can be rotated and stored in the drawer. The present invention will be described below with reference to the accompanying drawings.

図１および図２は本発明の画像形成装置の排紙装置の一実施例である。
図１において、スモールバスケット１をドロア２にセットする際は、仕切り板３をドロア２上にドロア２とのなす角度が９０度となるようにセットされる。 1 and 2 show an embodiment of a paper discharge device of the image forming apparatus of the present invention.
In FIG. 1, when the small basket 1 is set on the drawer 2, the partition plate 3 is set on the drawer 2 so that the angle between the drawer 2 and the drawer 2 is 90 degrees.

このとき、仕切り板３が図２の状態のように収納されている場合は、スモールバスケット1をセットすることができないようになっており、さらに仕切り板３がドロア２上に所定の位置（９０度）にセットされない場合はスモールバスケット１と干渉しセットできなくなる。   At this time, when the partition plate 3 is stored as shown in FIG. 2, the small basket 1 cannot be set, and the partition plate 3 is placed on the drawer 2 at a predetermined position (90 If it is not set, it will interfere with the small basket 1 and cannot be set.

仕切り板３を正常にセットした場合は、スモールバスケット３セットの際のテーブルアーム昇降による安全性を確保することができる。   When the partition plate 3 is normally set, safety by raising and lowering the table arm when the small basket 3 is set can be ensured.

また図２において、ラージバスケット４をドロア２にセットする際は、仕切り板３をドロア２上に図２の如く折り畳む。この際に仕切り板３が折り畳まれていない場合は、ラージバスケット４と干渉しセットできなくなり、誤挿入を防ぐことができる。   In FIG. 2, when the large basket 4 is set on the drawer 2, the partition plate 3 is folded on the drawer 2 as shown in FIG. 2. At this time, when the partition plate 3 is not folded, it cannot be set by interfering with the large basket 4, and erroneous insertion can be prevented.
