【発明の属する技術分野】
本発明は、インクジェット等のプロッタにおける用紙収納装置に関する。
【０００２】
【従来の技術】
従来、インクジェットプロッタでロール紙を使用して作画する場合、作画済みの図面用紙を収納する用紙収納装置のタイプには２種類ある。その１つは、図７（Ａ）に示すバスケットタイプであり、シートにより構成されている。プロッタ（２）のプラテン（４）上で作画された用紙（６）は、１フレーム（１ページ）分がカッターによってカットされ、脚体（８）に支承されたＵ字状の用紙収納部（１０）に収納される。
用紙収納装置の他の種類は、図７（Ｂ）に示す平面状の用紙載置傾斜面（１２）を有するものであり、傾斜面（１２）は複数本の金属棒により構成されている。プラテン（４）上の作画済みの用紙（６）は、カッターによって切断され、用紙収納部（１４）の用紙載置傾斜面（１２）上に何枚も重ねて収納される。
【０００３】
【発明が解決しようとする課題】
上記図７（Ａ）に示すＵ字状バスケット型の用紙収納装置では、コシがなく印字率の低い図面用紙は、作画が終了してカット後、用紙が丸まってＵ字状の用紙収納部内に何枚も収納可能であるが、逆に、コシのある用紙（例えばフィルム）や、印字率の高い図面用紙は、作画終了後、用紙が丸まらないので、作画済みの用紙を何枚も収納することができないという問題点がある。
また、上記図７（Ｂ）に示す傾斜面型の用紙収納装置では、コシのある用紙や印字率の高い用紙は、作画が終了してカット後、用紙が丸まらないので、用紙を傾斜面上に何枚も収納可能であるが、逆に、コシのない、印字率の低い図面用紙は、作画が終了してカット後、丸まってしまい、傾斜面上に何枚も安定的に収納することができないという問題点がある。
本発明は上記問題点を解決することを目的とするものである。
【０００４】

【発明の実施の形態】
以下に本発明の実施の形態を、添付した図面を参照して詳細に説明する。
図１及び図５において、（８）は、プロッタ（２）の脚体であり、左右に所定間隔を存して、一対垂直に設けられ、一対の脚体（８）（８）間に、２本のサイドステー（１６）（１８）が架設されている。（２０）は、第１の収納シートであり、これの一方の縁部に筒状部（２２）が形成され、この筒状部（２２）に軸（２４）が挿入されている。第１の収納シート（２０）の縁部の近傍には、結合用の止めホック（２６）が設けられている。（２８）は、第２の収納シートであり、一方の縁部（３０）を残して、内部に固い芯材が配置されている。
【０００６】
第２の収納シート（２８）の一方の面には、結合用の止めホック（３２）が複数段の並列線上に、各々、複数配設されている。第２のシートの一方の縁部（３０）には、開閉自在な筒状部が形成され、該筒状部は、止めホックにより筒状に止めることができ、ホックを外すと、平面状に展開自在となっている。
【０００７】
（３４）は吊り上げ部材であり、その一方に引掛部（３６）が形成され、他方に結合用の止めホック（３８）が配設されている。前記吊り上げ状部材（３４）は３乃至４枚用意されている。
（４０）は、一対のトレイフックであり、一端部には、前記軸（２４）をスライド自在に受け入れるためのリング部（４２）が形成され、他方には、前記上下のサイドステー（１６）（１８）と係合し、トレイフック（４０）の位置を固定するための、係合部（４４）（４６）が形成されている。
【０００８】
次に、用紙収納装置の組み立て方法について説明する。
まず、用紙収納装置を丸まってしまう作画済み用紙を収納するのに適した形状に組み立てる場合について説明する。
まず、予め、第１と第２の収納シート（２０）（２８）を、図３に示すように互いの結合長さが最長となるように、互いの縁部を止めホック（２６）（３２）により結合しておく。軸（２４）に、２本の中の１本のトレイフック（４０）のリング部（４２）、第１の収納シート（２０）の筒状部（２２）、２本の中の他の１本のトレイフック（４０）のリング部（４２）の順で通し、軸（２４）の両端に抜脱防止のためのキャップ（４８）をする。
【０００９】
次に、２本のサイドステー（１６）（１８）にそれぞれトレイフック（４０）の係合部（４４）（４６）を引掛け、トレイフック（４０）を、脚体（８）に、下向きの荷重に対して揺動しないように支承する。次に、第２の収納シート（２８）の開放側の縁部（３０）を下側のサイドステー（１８）に巻き付け、外側で止めホック（５０）を留めて、筒状部を閉じ、第２の収納シート（２８）の縁部（３０）を下側のサイドステー（１８）に連結する。
【００１０】
これにより、用紙収納装置の組み立てが完了し、プロッタ（２）の脚体（８）間に側面形状がＵ字状の、シート（２０）（２８）による用紙収納部（５２）が形成される。
カット紙あるいは、ロール紙に対して、１フレーム分の作図が完了すると、ロール紙の場合は、カッターにより所定の寸法にカットされ、矢方向Ｅから、用紙収納部（５２）に落下する。用紙収納部（５２）に落下した用紙が、コシがなく印字率が低い場合には、用紙は、用紙収納部（５２）内で丸まってしまい、この状態で順次多数の作画済み用紙（６）が用紙収納部（５２）内に収納される。即ち、プロッタ（２）が印字率（データ量）の低い印字を行う場合、Ｕ字型の用紙収納部（２０）が選択される。
【００１１】
次に、用紙収納部の形状を、作画終了後、丸まらない用紙を収納するのに適した形状に変更する場合について説明する。
まず、第１の収納シート（２０）と第２の収納シート（２８）とのホックによる結合を一旦外し、長さ方向に互いに広い範囲で重なるように、第１の収納シート（２０）と第２の収納シート（２８）との結合位置をずらし、図（４）に示すように、両者を止めホック（２６）（３２）で留める。この結合状態において、両シート（２０）（２８）の全長は、Ｕ字状の用紙収納部（５２）を形成したときよりも短くなる。
【００１２】
次に、複数枚の吊り上げ部材（３４）の各々の一方を止めホック（３８）（３２）によって、第２の収納シート（２８）の一方の縁部（３０）から所定間隔離れた位置に結合し、各吊り上げ部材（３４）の引掛部（３６）を、上側のサイドステー（１６）に引掛ける。これにより、第２の収納シート（２８）は、吊り上げ部材（３４）によって吊り上げられ、下側のサイドステー（１８）を中心として、第１図中、反時計方向に傾斜し、第１の収納シート（２０）は、略平面状の用紙載置傾斜面（５６）を有する側面Ｖ字状の用紙収納部（５４）が形成される。
【００１３】
コシのあるあるいは印字率の高い図面用紙は、作画終了後、用紙が丸まらないで平面状を保持した状態で矢方向Ｅから用紙収納部（５４）に降下し、傾斜面（５６）に載置され、Ｖ字状の係止部（５８）に係止される。用紙（６）の、この傾斜面（５６）からはみ出た部分は、自重により、第１の収納シート（２０）の筒状部（２２）から垂れ下がる。このような状態で、１フレーム分の作画が完了するごとに所定の寸法に切断された図面用紙（６）は、何枚も傾斜面（５６）上に重なって収納される。
上記実施形態において、図３に示すように、第１のシート（２０）と第２のシート（２８）とをホック（２６），（３２）を介して、互いの結合長さが最長となるように結合し、該結合したシート状部材の一方側をサイドステー（１８）を介してプロッタに脱着自在に支承し、シート状部材の他方側を軸（２４）とトレイフック（４０）のリング部（４２）を介して、プロッタに脱着自在に支承し、シート状部材の中間部がＵ字状に弛むようにした構成は、第１の手段を構成している。また、図４に示すように、第１のシート（２０）と第２のシート（２８）とをホック（２６），（３２）を介して、互いの結合長さが最長の状態よりも所定長さ短くなるように結合し、該結合したシート状部材の第２のシート（２８）側に吊り上げ部材（３４）を脱着自在に取り付け、該吊り上げ部材（３４）の引掛部（３６）を、第２のシート（２８）がサイドステー（２４）を中心として傾斜するように、プロッタ側のサイドステー（１６）に脱着自在に支承し、第２のシート（２８）のサイドステー（１８）を中心とする傾斜により第１のシート（２０）に平板状の用紙載置傾斜面が形成されるようにした構成は、第２の手段を構成している。これら、第１の手段と第２の手段は、プロッタに選択的に脱着できるように構成されている。
【００１４】
尚、上記実施形態は、手操作によって、印字率の高低に応じて用紙収納部の形状を変更するものであるが、図６に示すようにモータ等のアーム駆動装置（６０）の出力側に可動アーム（６２）を連結し、該可動アーム（６２）に連結する軸を、前後の縁部がトレイフック（図示省略）と、下側のサイドステー（１８）に支承されたシート（６４）の所定位置に対向配置し、プロッタ側で印字作図のデータ量を検出し、印字率（データ量）によって、用紙収納部の形状を、自動的に変更しても良い。この実施の形態では、印字率小のとき、可動アーム（６２）は上昇位置に移働し、シート（６４）は、Ｕ字状の用紙収納部を構成する。印字率大のとき、可動アーム（６２）は下降位置に移動し、軸によってシート（６４）を加圧して変形させ、略平面状の用紙載置の傾斜面を有する側面Ｖ字状の用紙収納部を構成する。
【００１５】

The second means couples the first and second sheets so that the coupling length is shorter than the longest state by a predetermined length, and the lifting member can be attached to and detached from the second sheet side of the sheet-like member. The second sheet is lifted by the lifting member so as to be tilted about its support portion, and a substantially flat sheet placement inclined surface is formed on the first sheet by the tilt, Hard core material inside the second sheet Paper storage device plotter according to claim 1, characterized in that the placed.

In a paper storage device of a plotter in which the drawn paper descending from the platen is stored in a paper storage portion formed of a sheet-like member, the shape of the paper storage portion is suitable for storing many rounded drawings. It can be changed to either a U-shaped shape or a shape having a substantially flat sheet-mounting inclined surface suitable for storing a large number of planar drawings. The shaft connected to the movable arm of the arm drive device is opposed to a predetermined position of the sheet-like member, and the shaft is moved to a position where the sheet-like member loosens in a U-shape. And the shaft can be moved in the direction in which the sheet-like member is pressed, so that a substantially flat sheet placement inclined surface is formed on the sheet-like member by the pressing, and the arm driving means is driven. The sheet-like part Intermediate portion plotter paper storage device being characterized in that the selectable one of the states substantially flat sheet holding 置傾 slope is formed on the sheet member in a state in which slack in the substantially U-shaped.
