Description

【０００１】
【発明の属する技術分野】
本発明は、複写機、プリンター、原稿送り装置や印刷機などの中を搬送される用紙などのシートを対象にして、その挙動を計算機によりシミュレーション解析した結果を表示するための表示装置および表示方法に関する。
【０００２】
【従来の技術】
近年コンピュータ装置の性能向上に伴い、機械設計のための一手法としてコンピュータ装置を用いたシミュレーションが広く行なわれるようになってきた。
【０００３】
設計段階において、実際に物を作る前からさまざまな条件で設計物の機能を検討することは、試作品を作り試験を行なう工数を低減でき、開発期間及び費用を低減できる。これは、企業活動に対して有益であるのみならず、資源の節約等の面から、地球環境に対する配慮もできるようになり、その重要性は高い。
【０００４】
現在、多くのシミュレーションプログラムが市販されているが、これらは汎用的なシミュレーションプログラムであるので、使いづらかったり又は機能が不足している場合がある。したがって、特定の現象だけを解析する場合には専用の解析システムを用いた方が効率良く解析できると共に、どの設計者でも容易に操作できるようにすることができる。
【０００５】
そこで、複写機、プリンタ装置、原稿送り装置又は印刷装置等の中で搬送される用紙等のシートの挙動をシミュレートするための条件設定や、シミュレート後の結果を設計者が有効活用するためのデータ処理方法および装置、設計支援装置などが本発明者により出願され、特開平１１−１１６１３３、特開平１１−１２０２２０、特開平１１−１９５０５２、特開平１１−２８２８２５等の公報に掲載されている。
【０００６】
これらの発明によりデータ処理装置の表示部あるいはコンピュータのディスプレイ装置にて、シートが搬送される過程での変形挙動のシミュレート結果が動画として可視化され、例えば、シートを案内する搬送ガイドとシート先端との当接角度などを設計者が容易に確認する事ができる。また、同時にシートと搬送ガイドとの摩擦抵抗値が確認できる。
【０００７】
【発明が解決しようとする課題】
しかしながら、上記従来における表示方法においては、以下に述べる問題点がある。
【０００８】
シート搬送経路全体（例えば複写機で、トレイから排紙するまで）を移動するシートの搬送挙動を動画表示する場合、画像が荒くなって必要なシートの変形状態が確認できない不具合が生じた。部分的に拡大表示を行い十分な解像度で動画表示は可能であるが、シートの移動に併せてユーザーが操作を行わなければならず、面倒であった。また、部分的な拡大と全体表示を同時に観察する事も重要であるが、上記発明だけでは不可能であった。
【０００９】
図１は、従来技術によるシートの搬送挙動の表示例を示す図である。図中、全搬送経路中を移動するシート２２が描画領域１５中に描画されている。ここで、シートを案内する搬送ガイド２０は線分として描画されており、直線や円弧などで構成されている。また、ローラ２１が円として表示してある。ところが、全搬送経路が描画できるような縮尺を用いているため点線で囲んだ領域２３にはシート先端が位置するが、画像が荒くてユーザーに分かりづらい。
【００１０】
図２は、指定領域を拡大した表示例を示す図である。図２において、表示部３に、拡大した領域２３が表示される。ローラ対２４ａと２４ｂで送り出されたシート２２の先端２２ａは搬送経路２５ａから搬送経路２５ｂへ移ろうとしている。しかし、カール（曲がり癖）があるためシート先端２２ａは搬送経路２５ｂへ進入する余裕度が極端に低下し、紙詰まり、あるいはその可能性が非常に高いことが予想される。
【００１１】
ユーザーは最初に、図２のように全搬送経路が示される縮尺で表示しその流れをマクロ的に把握したがるのが普通である。そして、自分が気になる領域で例えば先端が停留する恐れが無いかを詳細に観察したい要望が強い。しかし、従来技術では図２の状態でアニメーションを停止し、領域２３が拡大表示されるように複数の操作を行う。確認後は再び全搬送経路全体が表示されるように縮尺を元に戻してアニメーションを見ていく。
【００１２】
また、ユーザーが予期しなかった場所で不具合がある場合、大きな縮尺のままでは見過ごしやすい。
【００１３】
そこで、本発明の第一の課題は、複写機、プリンター装置、原稿送り装置又は印刷装置等の中で搬送される用紙等のシート挙動をシミュレートした後、その結果を効果的な動画で確認することができる表示装置を提供することである。
【００１４】
また、本発明の第二の課題は、同様に、表示方法を提供することである。
【００１５】
さらに、本発明の第三の課題は、上記のような装置での処理をコンピュータに行なわせるためのプログラムを格納した記憶媒体を提供することである。
【００１６】

【００２２】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００２３】
図３は、本発明の一実施例に係る表示装置の構成例を示す図である。例えば、表示装置１００は、図３に示すように、入力部１、ＣＰＵ２、表示部３、外部記憶装置４、データメモリ５、プログラムメモリ６、データバス７、主制御部１４を有する。
【００２４】
主制御部１４は、表示装置１００全体を制御する。
【００２５】
入力部１は、キーボード、マウスなどのポインティングデバイスなどで、ユーザーが数値を入力したり表示部内の位置を指定したりする。
【００２６】
ＣＰＵ２は、各種演算処理を行う。
【００２７】
表示部３は、ディスプレイ装置などで搬送されるシートの変形過程をアニメーションなどの描画表示がなされる。
【００２８】
外部記憶装置４は、シミュレーション結果や本発明の一実施例に係る表示処理をコンピュータにて実行可能なプログラムとし、例えばフロッピーディスクやＣＤ−Ｒ／ＲＷ、ＭＯなど記録媒体へ記録されたデータを読み込むあるいは書き込むことができる。
【００２９】
データメモリ５は、読込んだシミュレーション結果などを記憶するシミュレーション結果記憶部９と、ユーザーが特に詳しくシートの挙動を拡大表示などさせたい領域などを記憶する表示領域記憶部８とを有する。
【００３０】
プログラムメモリ６は、前記プログラムを外部記憶装置４に差し込んだ記録媒体１５から読込み記憶しても良いし、ＲＯＭでも良い。また、プログラムメモリ６は、図３に示すように、複数表示を行う複数表示処理部１０と、全搬送経路表示に必要な描画領域を算出する描画領域算出部１１と、描画領域へのシートの進入を判断する進入判定部１２、拡大して表示するための拡大表示領域を算出する拡大表示領域算出部１３からなる。
【００３１】
全搬送経路の表示を必ず実施する場合について図４及び図５で説明する。
【００３２】
図４は、表示処理を説明するフローチャート図である。
【００３３】
描画領域算出部１１は、全搬送経路表示用の縮尺と実空間での描画領域を算出する（ステップＳ１１）。つまり、データメモリ５に記憶されているシミュレーション結果記憶部９から搬送ガイドデータを読み込む。シミュレーションでの空間すなわち実空間で、搬送ガイドが位置する最大と最小の値を求め描画領域を算出し、表示部３での表示領域とから縮尺を算出する。
【００３４】
ステップＳ１１で算出された描画領域に基づいて、搬送ガイドの描画表示処理を実行する（ステップＳ１２）。これによって、搬送経路全体が表示部３に表示される。
【００３５】
このユーザーの指定によって、描画表示の数とそれぞれの実空間における描画領域が入力される（ステップＳ１３）。
【００３６】
図５は、搬送経路全体と拡大したい領域の例を示す図である。ユーザーは拡大表示したい領域を、例えばマウスを用いて、図５に示される搬送経路全体から拡大したい領域２３及び２６と指定する。すなわち、図４において描画表示の数として２が設定される。また、領域２３と２６の表示領域での座標が認識される。これに、縮尺を用いれば拡大したい実空間の描画領域がわかる。
【００３７】
更に、ユーザーによって、表示部空間での表示領域が入力されと、その入力された表示領域が表示領域記憶部８へ格納される（ステップＳ１４）。表示部３のどの位置にどれぐらいの大きさで表示するかを、図５の拡大領域を指定したようにマウスで設定したり、Ｗｉｎｄｏｗｓのウィンドウの大きさを変えるように既に新しく生成された二つの表示ウィンドウの大きさを設定する。
【００３８】
これにより、表示部３での表示領域が決まると、拡大表示領域算出部１３は、それぞれを描画表示するときの縮尺を算出する（ステップＳ１５）。
【００３９】
表示する時刻の設定を行う（ステップＳ１６）。そして、例えば、初期状態からアニメーションを開始するとして、順次、該当時刻でのシミュレーションデータ１７であるシート各部位の座標値を外部記憶装置４からあるいはデータメモリ５のシミュレーション結果記憶部９から読込む（ステップＳ１７）。
【００４０】
次に、シート進入判定部１２は、描画表示毎にその領域にシートが存在するかどうか否かを判断し（ステップＳ１９）、存在していればシートの各部位の表示領域での座標値を算出して（ステップＳ２０）、複数表示処理部１０によって描画表示処理が行われる（ステップＳ２１）。例えば、シート先端のみを見たいのであれば拡大表示はひとつのみで良く、表示領域を共有して用いたりすれば良い。あるいは、先端以外も表示したければ個別に描画表示したり、その領域にシートが存在しなければ一時的に表示を隠しても良い。
【００４１】
一方、ステップＳ１９において、描画表示毎にその領域にシートが存在しない場合、ステップＳ２２へ進む。
【００４２】
更に、ユーザーによって指定された描画表示がまだあるか否かを判断する（ステップＳ２２）。描画表示がまだある場合、ステップ１８へ戻り、上記処理を繰り返す。
【００４３】
一方、描画表示がない場合、最後の時刻まで描画表示をしたか否かを判断する（ステップＳ２３）。最後の時刻まで描画表示をしていない場合、ステップＳ１６へ戻り、上記処理を繰り返す。一方、最後の時刻まで描画表示をした場合、表示処理を終了する。
【００４４】
図６は、領域２３に先端がある場合の表示例を示す図である。図６において、全搬送経路を表示するウィンドウ２７と、領域２３を拡大して表示するウィンドウ２８とが表示部３に表示される。ウィンドウ２８において、シート先端２２ａが搬送経路２５ａから搬送経路２５ｂへ移るところで、シート先端２２ａのカール（曲がり癖）によって、ジャムの発生が予測できる。
【００４５】
図７は、表示指定領域にシート先端がある場合の表示例を示す図である。図７において、全搬送経路を表示するウィンドウ２７と、領域２６を拡大して表示するウィンドウ２９とが表示部３に表示される。ローラ対３１ａと３１ｂのニップ部へシート先端２２ａがシート２２のカールのために進入できないでいる状態が分かる。この表示によって、ジャムの発生が予測できる。
【００４６】
上述より、拡大したい領域へシートが進入し存在している場合の表示処理について説明した。
【００４７】
シートの特定部位に着目しこれが移動する場合に拡大表示する領域もいっしょに移動させる表示処理について説明する。
【００４８】
図８は、シート移動に応じて拡大表示が変化する表示処理を説明するフローチャート図である。図８中、図４に示すステップＳ１１からＳ１５までの処理が同様に行われるため、そのステップが省略され、また、その説明を省略する。
【００４９】
図８において、表示時刻を設定し（ステップＳ３１）、該当時刻のシミュレーションデータ１７から各部位の座標値を読込む（ステップＳ３２）。
【００５０】
続けて、着目するシート部位ごとに処理を行う（ステップＳ３３）。例えば、シート先端と後端が設定されている場合、表示領域のどこに着目部位を描画するかは種々考えられる。例えば、中心に置くとか、移動方向により表示領域の所定位置になるように適宜設定しておく。これにより描画領域を算出しその値を更新する（ステップＳ３４）。次に、シート各部位の表示領域での座標値算出を行い（ステップＳ３５）、描画表示処理を行う（ステップＳ３６）。
【００５１】
描画表示処理が終了すると、描画表示はまだあるか否かを判断し（ステップＳ３７）、まだある場合、ステップＳ３３へ戻り上記処理を繰り返す。一方、描画表示がない場合、ステップＳ３８を実行する。
【００５２】
ステップＳ３８において、最後の時刻まできたか否かを判断し、最後の時刻まできていない場合、ステップＳ３１へ戻り上記処理を繰り返す。一方、最後の時刻まできている場合、表示処理を終了する。
【００５３】
図８に示す表示処理によって、例えば、先端に着目すればジャム発生につながる挙動の存在を常に確認できる。また、後端に着目すればガイドへ強く衝突する様子が観察できる。
【００５４】
図９は、シートの先端及び後端を常に拡大表示するように設定した場合の表示例を示す図である。図９において、全搬送経路を表示するウィンドウ２７と、領域２６を拡大して表示するウィンドウ３２と、領域３４を拡大して表示するウィンドウ３３とが表示部３に表示される。ウィンドウ３２によって、ローラ対３１ａと３１ｂのニップ部へシート先端２２ａがシート２２のカールのために進入できないでいる状態が分かる。また、ウィンドウ３３によって、シート２２の後端が表示される。
【００５５】
上述より、本発明によれば、複数表示領域を設け、同時刻で異なる個所でのシートの変形状態を容易に確認することができ、効率的な設計支援が可能となる。
【００５６】
また、搬送経路全体でのシート搬送挙動とその時の拡大表示を同時に可視化できるため、効率的な設計支援が可能となる。
【００５７】
更に、ユーザーが拡大表示したい領域を初期に設定しておくことで、複数の拡大領域で効率的に表示が行われ、効率的な設計支援が可能となる。
【００５８】
また、シート移動に伴って拡大表示領域が自動で移動するため、シートの任意位置に着目しその位置での挙動を追跡でき、操作が省略されて効率的な設計支援が可能となる。
【００５９】
更に、シート移動に伴ってシート先端と後端の挙動を自動で追跡できる。先端はジャム発生とかかわりが強く全体表示といっしょに先端の詳細な挙動が自動で確認できる。また、後端はガイドと強く衝突する場合などは騒音発生の原因となるため、そのような挙動を常に観察可能となり、効率的で有効な設計支援が容易となる。
【００６０】
また、コンピュータを用いて表示装置が実現でき、上記効果が容易に得られる。
【００６１】
上記実施例において、本発明は、上記機器以外でも、シートを移動させる特徴を持つ、キャシュディスペンサー、抄紙機などで搬送されるシートの挙動を、計算機にて解析した結果の表示処理に適応することができる。
【００６２】
【発明の効果】
以上、説明してきたように、請求項１乃至４記載の本願発明によれば、複数の表示箇所での媒体の搬送状態を、異なる縮尺で同時にシミュレートすることができる表示装置を提供することができる。
【００６３】
また、請求項５乃至８記載の本願発明によれば、複数の表示箇所での媒体の搬送状態を、異なる縮尺で同時にシミュレートすることができる表示方法を提供することができる。
【００６４】
さらに、請求項９乃至１１記載の本願発明によれば、上記のような表示装置での処理をコンピュータに行なわせるためのプログラムを格納した記憶媒体を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a display device and a display method for displaying a result of a simulation analysis of a behavior of a sheet such as a sheet conveyed in a copying machine, a printer, a document feeder, a printing machine, or the like by a computer. About.
[0002]
[Prior art]
In recent years, with the improvement in performance of computer devices, simulations using computer devices have become widely used as a method for machine design.
[0003]
Examining the function of a design under various conditions before actually making the product at the design stage can reduce the man-hours for making a prototype and performing the test, and can reduce the development period and cost. This is not only useful for corporate activities, but also makes it possible to consider the global environment in terms of resource saving and the like, and its importance is high.
[0004]
At present, many simulation programs are commercially available, but these are general-purpose simulation programs, so that they may be difficult to use or lack functions. Therefore, when analyzing only a specific phenomenon, it is possible to perform analysis efficiently by using a dedicated analysis system, and any designer can easily operate.
[0005]
Therefore, in order to make effective use of the condition settings for simulating the behavior of sheets such as paper conveyed in a copying machine, printer, document feeder, or printing device, and the results after simulation No. 11-116133, JP-A-11-120220, JP-A-11-195052, JP-A-11-282825, and the like have been filed by the present inventors. .
[0006]
According to these inventions, the simulation result of the deformation behavior in the process of conveying the sheet is visualized as a moving image on the display unit of the data processing apparatus or the display unit of the computer. For example, the conveyance guide for guiding the sheet, the sheet leading edge, It is possible for the designer to easily check the abutment angle. At the same time, the frictional resistance value between the sheet and the conveyance guide can be confirmed.
[0007]
[Problems to be solved by the invention]
However, the conventional display method has the following problems.
[0008]
When displaying the moving behavior of a sheet moving along the entire sheet conveying path (for example, in a copying machine, until the sheet is discharged from the tray), a problem arises in which the image becomes rough and the necessary deformation state of the sheet cannot be confirmed. Partially enlarged display and moving image display with sufficient resolution are possible, but the user has to perform an operation as the sheet moves, which is troublesome. It is also important to observe partial enlargement and the entire display at the same time, but this is not possible with the above invention alone.
[0009]
FIG. 1 is a diagram illustrating a display example of a sheet conveyance behavior according to a conventional technique. In the drawing, a sheet 22 moving in the entire conveyance path is drawn in the drawing area 15. Here, the conveyance guide 20 for guiding the sheet is drawn as a line segment, and is composed of a straight line, an arc, or the like. The roller 21 is displayed as a circle. However, since the scale that can draw the entire transport path is used, the leading edge of the sheet is located in the area 23 surrounded by the dotted line, but the image is rough and difficult for the user to understand.
[0010]
FIG. 2 is a diagram illustrating a display example in which the designated area is enlarged. In FIG. 2, an enlarged area 23 is displayed on the display unit 3. The leading end 22a of the sheet 22 fed by the roller pairs 24a and 24b is about to move from the transport path 25a to the transport path 25b. However, since there is a curl (curl), the margin of entry of the sheet leading edge 22a into the conveyance path 25b is extremely reduced, and it is expected that the possibility of paper jam or the possibility thereof is very high.
[0011]
As shown in FIG. 2, the user usually wants to display the entire transport path at a reduced scale so as to grasp the flow in a macro manner. And there is a strong demand to observe in detail whether there is no fear of the tip being stopped in an area of concern. However, in the prior art, the animation is stopped in the state of FIG. 2, and a plurality of operations are performed so that the region 23 is enlarged and displayed. After confirmation, the scale is returned to the original so that the entire transport path is displayed again, and the animation is viewed.
[0012]
Also, if there is a problem at a location that the user did not expect, it is easy to overlook it at a large scale.
[0013]
Therefore, the first problem of the present invention is to simulate the behavior of a sheet of paper conveyed in a copying machine, a printer device, a document feeding device, or a printing device, and confirm the result with an effective moving image. It is to provide a display device that can be used.
[0014]
Moreover, the 2nd subject of this invention is providing the display method similarly.
[0015]
Furthermore, the third object of the present invention is to provide a storage medium storing a program for causing a computer to perform the processing in the apparatus as described above.
[0016]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is a diagram illustrating a configuration example of a display device according to an embodiment of the present invention. For example, as illustrated in FIG. 3 , the display device 100 includes an input unit 1, a CPU 2, a display unit 3, an external storage device 4, a data memory 5, a program memory 6, a data bus 7, and a main control unit 14.
[0024]
The main control unit 14 controls the entire display device 100.
[0025]
The input unit 1 is a pointing device such as a keyboard or a mouse, and the user inputs a numerical value or designates a position in the display unit.
[0026]
The CPU 2 performs various arithmetic processes.
[0027]
The display unit 3 displays a drawing process such as an animation of a deformation process of a sheet conveyed by a display device or the like.
[0028]
The external storage device 4 is a program that can execute simulation results and display processing according to an embodiment of the present invention on a computer, and reads data recorded on a recording medium such as a floppy disk, CD-R / RW, or MO. Or you can write.
[0029]
The data memory 5 includes a simulation result storage unit 9 that stores the read simulation result and the like, and a display region storage unit 8 that stores a region that the user wants to display the sheet behavior in a particularly detailed manner.
[0030]
The program memory 6, to the pre-Symbol program from the recording medium 15 is inserted in the external storage device 4 may be read stored, it may be ROM. Further, as shown in FIG. 3 , the program memory 6 includes a plurality of display processing units 10 that perform a plurality of displays, a drawing region calculation unit 11 that calculates a drawing region necessary for displaying all conveyance paths, and a sheet to the drawing region. An entry determination unit 12 that determines entry and an enlargement display region calculation unit 13 that calculates an enlargement display region for display in an enlarged manner.
[0031]
The case where the display of all the transport routes is always performed will be described with reference to FIGS.
[0032]
FIG. 4 is a flowchart for explaining the display process.
[0033]
The drawing area calculation unit 11 calculates the scale for displaying the entire conveyance path and the drawing area in the real space (step S11). That is, the conveyance guide data is read from the simulation result storage unit 9 stored in the data memory 5. The drawing area is calculated by obtaining the maximum and minimum values at which the conveyance guide is located in the simulation space, that is, the real space, and the scale is calculated from the display area on the display unit 3.
[0034]
Based on the drawing area calculated in step S11, a drawing display process of the conveyance guide is executed (step S12). As a result, the entire conveyance path is displayed on the display unit 3.
[0035]
In accordance with the user's designation, the number of drawing displays and the drawing area in each real space are input (step S13).
[0036]
FIG. 5 is a diagram illustrating an example of the entire conveyance path and an area to be enlarged. The user designates areas to be enlarged as areas 23 and 26 to be enlarged from the entire conveyance path shown in FIG. 5 using, for example, a mouse. That is, 2 is set as the number of drawing displays in FIG. In addition, the coordinates of the display areas 23 and 26 are recognized. If the scale is used for this, the drawing area of the real space to be enlarged can be known.
[0037]
Further, when a display area in the display unit space is input by the user, the input display area is stored in the display area storage unit 8 (step S14). The position of the display unit 3 and the size of the display are set with the mouse so as to specify the enlargement area in FIG. 5 or the newly generated two-dimensional display is changed so as to change the size of the Windows window. Sets the size of one display window.
[0038]
Thus, when the display area on the display unit 3 is determined, the enlarged display area calculation unit 13 calculates a scale when each of them is drawn and displayed (step S15).
[0039]
The display time is set (step S16). For example, assuming that the animation is started from the initial state, the coordinate values of each part of the sheet, which is the simulation data 17 at the corresponding time, are sequentially read from the external storage device 4 or the simulation result storage unit 9 of the data memory 5 ( Step S17).
[0040]
Next, the sheet entry determination unit 12 determines whether or not a sheet exists in the area for each drawing display (step S19). If there is a sheet, the coordinate value in the display area of each part of the sheet is determined. After calculating (step S20), the multiple display processing unit 10 performs drawing display processing (step S21). For example, if only the leading edge of the sheet is to be viewed, only one enlarged display is required, and the display area may be shared. Alternatively, if it is desired to display other than the leading edge, the image may be drawn and displayed individually. If there is no sheet in the area, the display may be temporarily hidden.
[0041]
On the other hand, in step S19, if there is no sheet in that area for each drawing display, the process proceeds to step S22.
[0042]
Further, it is determined whether there is still a drawing display designated by the user (step S22). If there is still a drawing display, the process returns to step 18 to repeat the above processing.
[0043]
On the other hand, if there is no drawing display, it is determined whether or not drawing display has been performed until the last time (step S23). When the drawing display is not performed until the last time, the process returns to step S16 and the above process is repeated. On the other hand, when the drawing display is performed until the last time, the display process is terminated.
[0044]
FIG. 6 is a diagram illustrating a display example when the region 23 has a tip. In FIG. 6, a window 27 that displays the entire conveyance path and a window 28 that displays an enlarged area 23 are displayed on the display unit 3. In the window 28, when the sheet leading edge 22a moves from the conveying path 25a to the conveying path 25b, the occurrence of a jam can be predicted due to the curl of the sheet leading edge 22a.
[0045]
FIG. 7 is a diagram illustrating a display example when the sheet leading edge is in the display designation area. In FIG. 7, a window 27 that displays the entire conveyance path and a window 29 that displays an enlarged area 26 are displayed on the display unit 3. It can be seen that the sheet tip 22a cannot enter the nip portion between the roller pair 31a and 31b due to the curl of the sheet 22. The occurrence of the jam can be predicted by this display.
[0046]
From the above description, the display process when the sheet enters and exists in the region to be enlarged has been described.
[0047]
A display process for focusing on a specific part of the sheet and moving the area to be enlarged when the sheet moves will be described.
[0048]
FIG. 8 is a flowchart for explaining a display process in which the enlarged display changes according to the sheet movement. In FIG. 8, since the processing from step S11 to S15 shown in FIG. 4 is performed in the same manner, that step is omitted and the description thereof is omitted.
[0049]
In FIG. 8, the display time is set (step S31), and the coordinate value of each part is read from the simulation data 17 at the corresponding time (step S32).
[0050]
Subsequently, processing is performed for each sheet part of interest (step S33). For example, when the front end and the rear end of the sheet are set, there are various possible places in the display area where the target part is drawn. For example, it is set appropriately so as to be placed at the center or at a predetermined position in the display area depending on the moving direction. Thus, the drawing area is calculated and the value is updated (step S34). Next, coordinate values in the display area of each part of the sheet are calculated (step S35), and a drawing display process is performed (step S36).
[0051]
When the drawing display process is completed, it is determined whether or not there is a drawing display (step S37). If there is still a drawing display, the process returns to step S33 and the above process is repeated. On the other hand, if there is no drawing display, step S38 is executed.
[0052]
In step S38, it is determined whether or not the last time has been reached. If the last time has not been reached, the process returns to step S31 and the above processing is repeated. On the other hand, if the last time is reached, the display process is terminated.
[0053]
With the display processing shown in FIG. 8, for example, if attention is paid to the tip, it is possible to always confirm the presence of a behavior that leads to the occurrence of a jam. In addition, if attention is paid to the rear end, it is possible to observe a state of strong collision with the guide.
[0054]
FIG. 9 is a diagram illustrating a display example when the front end and the rear end of the sheet are set to be always displayed in an enlarged manner. In FIG. 9, a window 27 that displays the entire transport path, a window 32 that displays an enlarged area 26, and a window 33 that displays an enlarged area 34 are displayed on the display unit 3. By the window 32, it can be seen that the sheet leading end 22a cannot enter the nip portion of the roller pair 31a and 31b due to curling of the sheet 22. Further, the rear end of the sheet 22 is displayed by the window 33.
[0055]
As described above, according to the present invention, it is possible to provide a plurality of display areas and easily check the deformation state of the sheet at different locations at the same time, thereby enabling efficient design support.
[0056]
In addition, since the sheet conveyance behavior in the entire conveyance path and the enlarged display at that time can be visualized at the same time, efficient design support is possible.
[0057]
Furthermore, by setting an area that the user wants to enlarge and display at an initial stage, efficient display is performed in a plurality of enlarged areas, and efficient design support becomes possible.
[0058]
Further, since the enlarged display area automatically moves with the movement of the sheet, attention can be paid to an arbitrary position of the sheet, the behavior at that position can be traced, and the operation can be omitted, thereby enabling efficient design support.
[0059]
Further, the behavior of the leading edge and the trailing edge of the sheet can be automatically tracked as the sheet moves. The tip is strongly related to the occurrence of jam, and the detailed behavior of the tip can be automatically confirmed along with the whole display. In addition, when the rear end strongly collides with the guide, it causes noise, so that such behavior can always be observed, and efficient and effective design support is facilitated.
[0060]
In addition, a display device can be realized using a computer, and the above effects can be easily obtained.
[0061]
In the above-described embodiment, the present invention is applicable to display processing of results obtained by analyzing the behavior of a sheet conveyed by a cash dispenser, a paper machine, etc., which has a feature of moving a sheet, other than the above-described devices. Can do.
