Abstract

<P>PROBLEM TO BE SOLVED: To shorten operation time/eliminate a waste of the operation time in a dot-impact type bankbook printer and a bankbook printing mechanism. <P>SOLUTION: A printing state checking means is composed of a reading table for putting a printed bankbook in a fixed position, an image recognition mechanism for reading printed contents, and a control part which processes recognition data, performs collation with a specification value, computes a correction value and determines printing density. Quality differences, caused by differences among operators' skills, and the correction value are accurately computed through the use of the printing state checking means, so that the checking of printing after the input of the correction value can be finished by being performed only once and so that the shortening of the operation time/the elimination of the waste of the operation time can be performed. A controller and the target printer are connected together by a communication means, and the correction value, which is computed by the printing state checking means, can also be automatically set, so that an input mistake can be eliminated. Furthermore, the mechanism of the printing state checking means is built into the printer, so that the printer can be equipped with a mechanism for self-correcting and self-determining the printing state. <P>COPYRIGHT: (C)2004,JPO

【0001】
【発明の属する技術分野】
本発明は通帳に印字することを目的とするドットインパクト式通帳印字プリンタ及び通帳印字機構での印字位置ずれ補正方法及び印字濃度確認方法に関する。
【0002】
【従来の技術】
銀行などの金融機関で使用される通帳は、各金融機関毎に大きさや印字位置等の使用が異なる。従来、通帳印字プリンタ及び通帳印字機構の生産工程にてテスト用の通帳にテストパターンを印字し、その結果を測定治工具で測定し、印字位置のずれ量を算出し、該プリンタ及び印字機構の制御部に補正値をインプットして調整を行っていた。また、印字濃度においても、印字結果を限度見本と目視にて比較し、合否判定をおこなっていた。
【0003】
通帳取り扱い装置の印字ずれ補正方法が、下記の特許文献1に記載されている。この方法は、通帳にページマークを印字し、このページマークと通帳上端との距離を測定し、補正値を求めて通帳の膨らみなどの変形に対する印字開始位置のずれを補正し印字させるものである。
【0004】
【特許文献1】
特開平10−297041号公報
【0005】
【発明が解決しようとする課題】
通帳プリンタ及び通帳印字機構生産時に発生する個々の固有の印字位置のずれや印字濃度の補正及び調整を行う必要がある。前記公知例は、通帳の膨らみなどの変形に対する印字開始位置のずれを補正するものであり、前記課題を解決するものではない。通帳プリンタ及び通帳印字機構生産工程では、装置組立後所定の用紙にテストパターンを印字させ、測定治具により目視でずれを確認し、補正値を設定したのち再度テストパターンを印字して所定の印字位置に入っていることを確認している。この作業を所定の印字位置に印字されるまで繰り返す。この補正値は測定治具にて測定した結果をその都度計算または、作業者の経験から設定値を決定している。これにより、作業者毎に補正度合いがことなり、製品品質のばらつきがでる。さらに調整回数にも差がでる。また、通帳を印字するプリンタ及び印字機構においては、納入先によりその対象通帳の大きさ、印字位置が異なり、測定治具も納入先毎に作成管理する必要がある。また、印字濃度を判別比較する限度見本も、作成及び維持管理に多大な労力を必要としている。
【0006】
【課題を解決するための手段】
印字内容を読み取るための画像認識機構、各金融機関毎の印字位置規格値データ及び印字濃度限度データを保有し、画像認識機構からの認識処理データとの照合及び補正値の算出、印字濃度の判定を行う制御部を備え、作業者の力量による品質の差異のない正確な補正値を算出し、濃度判定を行う手段。また、該制御部とプリンタ及び印字機構を通信手段により接続し、算出した補正値を自動で設定する手段。さらに、印字装置内に上記の機構を盛り込むことにより、印字状態の自己修正、自己判定をおこなう手段。
【0007】
【発明の実施の形態】
図2に本発明を実施するための概略構成を示し、図1に示す本発明の処理ステップの概略に沿って実施の形態について述べる。ステップS1で、通帳プリンタ及び通帳印字機構(以下製品と呼ぶ)の機構的組立が完了し、製品の型式や納入先に応じた動作プログラムが該製品内部の制御部にインストールされると、製品は印字動作が可能となる。ステップS2で製品の構造的ばらつきの補正や調整確認のために、納入先仕様に合せたテスト用通帳1にテストパターン6を印字する。ステップS3で、テストパターンを印字したテスト用通帳1を通帳置き台2の所定の位置にセットする。ステップS4で、通帳置き台2にセットされたテスト通帳1の印字状態を認識部3により、読み取る。ステップS5では、対象となる製品型式、納入先を指定し、制御部4にて認識部3で読み取られた印字状態データを処理し、あらかじめ設定、保存されている印字位置規格値データテーブルや印字濃度限度見本データと照合を行う。ステップS6で納入先の印字規格値との差異を照合した結果から、製品の型式毎に設定されている補正値算出計算式により、補正値を算出し、表示部5に表示する。ステップS7で表示部5に表示された補正値をもとに、作業者が製品毎に設定されている従い、補正値を入力する。ステップS8では、ステップS6と同時に印字濃度などの判定処理を行い、結果を表示部5に表示する。ここでは、印字濃度限度見本データと照合結果から、濃淡、ドット抜け、余分な打点などの不正印字の有無を表示する。ステップS9にて、表示された結果から印字ヘッドと通帳間の距離や機構部調整を行う。
【0008】
図3にテストパターン6が印字されたテスト用通帳を示す。印字位置を確認する主な項目は、通帳左端面から印字行端面の距離A1、その距離A1の1行目と2行目の差と印字行の長さA2。また、通帳上端面から第1行目までの距離B1、1行目からページ間の空白を含めた最終行までの距離B2、行間B3である。これらの値を前記ステップ4で、通帳の幅Aや長さBとともに読取りを行う。
【0009】
また、これらの数値は、納入先金融機関毎に通帳の大きさ、印字文字の大きさなど異なり、印字位置の規格値が異なる。そのため、図4に示すような規格値データテーブルを作成し、制御部4に持たせる。この規格値データテーブルを基に、前記の測定結果と照合するものである。
【0010】
プリンタや印字機構は、通帳搬送機構であるローラの径や駆動させるモータの制御方式等により補正値の算出手段がその製品型式毎に異なり、補正値算出のための係数が設定されている。距離の差異を計測したのち、その型式毎に設定される係数により、補正値を算出する。このため規格値データテーブルには製品型式も登録しておく。
【0011】
以上の手段では、印字位置の補正値を算出したあとの製品への補正値の設定は作業者が、設定することとしているが、制御部4と製品を通信手段により接続することで、製品の制御部に直接、自動で補正値を設定することが可能となる。
【0012】
また、製品内部に認識部3や製品の制御部に前記処理機能を持たせることにより、生産時だけではなく、納入後の稼動時においての逐次補正が可能となり、さらに、印字濃度自己判断機能も付加されることになる。
【0013】
【発明の効果】
以上のように、本発明によれば1度のテスト印字により、設定しなければならない印字位置補正値を正確に算出でき、作業者のスキルに依存することなく均一な印字品質が得られる。テスト印字を繰り返す必要がなくなり、作業時間の大幅な短縮とテスト通帳の使用量が大幅に抑えられる。
【0014】
また、製品と直接通信手段で接続することにより、補正値の誤設定などの作業ミスが発生せず、作業効率の向上と確認作業の排除ができる。
【0015】
さらに、本機構を製品に組み込むことにより、生産時での細かな補正値設定などが不要となり、印字状態の自己監視機能として利用することができ、信頼性の向上につながる。

[0002]
[Prior art]
A passbook used by a financial institution such as a bank differs in use of a size, a printing position, and the like for each financial institution. Conventionally, in the production process of a passbook printing printer and a passbook printing mechanism, a test pattern is printed on a test passbook, the result is measured with a measuring jig, a printing position shift amount is calculated, and the printer and the printing mechanism are printed.

[Problems to be solved by the invention]
It is necessary to correct and adjust the individual print position shifts and print densities that occur during production of the passbook printer and the passbook printing mechanism. The known example corrects a shift of a printing start position due to a deformation such as a bulging of a passbook, and does not solve the above problem. In the production process of the passbook printer and passbook printing mechanism, after assembling the device, print a test pattern on the specified paper, check the deviation visually with a measuring jig, set the correction value, print the test pattern again, and print the specified pattern Make sure you are in position. This operation is repeated until printing is performed at a predetermined printing position. The correction value is calculated each time a result measured by a measuring jig is used, or a set value is determined from the experience of an operator. As a result, the degree of correction differs for each worker, and the product quality varies. Further, the number of adjustments also varies. In a printer and a printing mechanism for printing a passbook, the size and printing position of the target passbook differ depending on the delivery destination, and it is necessary to create and manage a measuring jig for each delivery destination. In addition, a limit sample for discriminating and comparing print densities requires a great deal of effort in preparation and maintenance.
[0006]
[Means for Solving the Problems]
It has an image recognition mechanism for reading the print contents, print position standard value data and print density limit data for each financial institution, collates with recognition processing data from the image recognition mechanism, calculates correction values, and determines print density. Means for calculating an accurate correction value having no difference in quality due to the ability of an operator and performing density determination. Means for connecting the control unit with a printer and a printing mechanism by means of communication means and automatically setting the calculated correction value; Further, means for performing self-correction and self-judgment of a printing state by incorporating the above mechanism in the printing apparatus.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 2 shows a schematic configuration for carrying out the present invention, and the embodiment will be described along the outline of the processing steps of the present invention shown in FIG. In step S1, the mechanical assembly of the passbook printer and the passbook printing mechanism (hereinafter, referred to as a product) is completed, and an operation program corresponding to the product type and delivery destination is installed in the control unit inside the product. Printing operation is enabled. In step S2, a test pattern 6 is printed on the test passbook 1 in accordance with the delivery destination specification in order to correct the structural variation of the product and confirm the adjustment. In step S3, the test passbook 1 on which the test pattern is printed is set at a predetermined position on the passbook holder 2. In step S <b> 4, the print state of the test passbook 1 set on the passbook holder 2 is read by the recognition unit 3. In step S5, the target product model and delivery destination are specified, the control unit 4 processes the print state data read by the recognition unit 3, and sets and stores the print position specification value data table and print Check with the concentration limit sample data. In step S6, a correction value is calculated from the result of collation with the printing standard value of the delivery destination by a correction value calculation formula set for each product model, and displayed on the display unit 5. Based on the correction value displayed on the display unit 5 in step S7, the operator inputs the correction value according to the setting for each product. In step S8, determination processing such as print density is performed simultaneously with step S6, and the result is displayed on the display unit 5. Here, based on the print density limit sample data and the collation result, the presence or absence of illegal printing such as shading, missing dots, and extra dots are displayed. In step S9, the distance between the print head and the passbook and the mechanism are adjusted based on the displayed result.
[0008]
FIG. 3 shows a test passbook on which the test pattern 6 is printed. The main items for checking the print position are the distance A1 from the left end face of the passbook to the end face of the print line, the difference between the first and second lines of the distance A1, and the length A2 of the print line. Further, a distance B1 from the upper end face of the passbook to the first line is a distance B2 from the first line to a last line including a space between pages, and a line spacing B3. These values are read in step 4 together with the width A and length B of the passbook.
[0009]
Further, these numerical values are different depending on the destination financial institution, such as the size of the passbook, the size of the printing characters, and the standard value of the printing position is different. Therefore, a standard value data table as shown in FIG. Based on the standard value data table, the data is collated with the measurement result.
[0010]
In printers and printing mechanisms, means for calculating a correction value differs for each product model depending on the diameter of a roller serving as a passbook transport mechanism, a control method of a motor to be driven, and the like, and a coefficient for calculating a correction value is set. After measuring the difference in distance, a correction value is calculated by a coefficient set for each model. Therefore, the product model is also registered in the standard value data table.
[0011]
In the above means, the operator sets the correction value for the product after calculating the correction value of the printing position, but by connecting the control unit 4 and the product by communication means, It is possible to automatically set the correction value directly in the control unit.
[0012]
In addition, by providing the processing function to the recognition unit 3 and the control unit of the product inside the product, it is possible to perform the correction not only at the time of production but also at the time of operation after delivery, and the print density self-judgment function is also provided. Will be added.
[0013]
【The invention's effect】
As described above, according to the present invention, the print position correction value to be set can be accurately calculated by one test print, and uniform print quality can be obtained without depending on the skill of the operator. This eliminates the need to repeat test printing, greatly reducing work time and greatly reducing the amount of test passbooks used.
[0014]
Further, by directly connecting to the product by the communication means, work errors such as erroneous setting of the correction value do not occur, thereby improving the work efficiency and eliminating the check work.
[0015]
Further, by incorporating this mechanism into a product, it is not necessary to set a fine correction value at the time of production, and the mechanism can be used as a self-monitoring function of a printing state, leading to an improvement in reliability.
