Description

パターン設定装置、パターン設定方法及びプログラムPATTERN SETTING DEVICE, PATTERN SETTING METHOD, AND PROGRAM
　本発明は、パターン設定装置、パターン設定方法及びプログラムに関し、特に、ドットの集合からなるパターンを印字のために設定するパターン設定装置、パターン設定方法及びプログラムに関する。 The present invention relates to a pattern setting device, a pattern setting method, and a program, and more particularly to a pattern setting device, a pattern setting method, and a program for setting a pattern composed of a set of dots for printing.
　近年、工業製品の生産工程などでは、例えば文字を工業製品に直接描画或いは刻印して、製品の管理やトレーサビリィティを実現するダイレクトマーキング技術が注目されている。 In recent years, in the production process of industrial products, for example, direct marking technology that realizes product management and traceability by drawing or engraving characters directly on the industrial products has attracted attention.
　工業製品に直接形成された文字は、例えばラベルなどのように製造工程で剥離する心配がなく、汚染による劣化や経年劣化なども比較的少ない。このため、高温や、薬品などにさらされる劣悪な環境下にある製造工程などでは、ダイレクトマーキング技術は必要不可欠な技術になりつつある。 Characters directly formed on industrial products do not have to worry about peeling off during the manufacturing process, such as labels, and have relatively little deterioration due to contamination or aging. For this reason, direct marking technology is becoming an indispensable technology in a manufacturing process in a poor environment exposed to high temperatures or chemicals.
　このようなダイレクトマーキング技術としては、ＹＡＧレーザやＣＯ２レーザなどで、対象物に非接触でマーキングを行う方法と、例えばピンなどで対象物の表面を打刻してマーキングを行う方法とがある。 As such a direct marking technique, there are a method of performing non-contact marking on an object with a YAG laser or a CO 2 laser, and a method of marking by marking the surface of the object with a pin or the like, for example. .
　対象物の表面を打刻してマーキングする方法は、金属部品などによく用いられるマーキング方法である。かかるマーキング方法は、例えば特許文献１に記載された打刻装置によって実現される。 The method of marking by marking the surface of an object is a marking method often used for metal parts. Such a marking method is realized, for example, by a stamping device described in Patent Document 1.
特開平８－２７６６０７号公報JP-A-8-276607
　特許文献１に記載された装置に代表される打刻装置により文字を打刻する場合、文字のパターンは、マトリクス上のドットの配置により表されることになる。また、文字を打刻する場合は、文字に下線を付したパターンを打刻する場合もある。
　その際、例えば打刻する文字が英数字であれば、打刻された文字により形成される文字列の外観上のバランスを考慮する必要があり、また、下線が付されることがあり得ることも考慮する必要がある。このため、大文字や数字については、図１５に示すように、小文字より中心を上寄りとし、マトリクスの最下行にドットを配置しないようにしてパターンが設定されていた。
　しかし、図１５のようなパターンを用いると、大文字や数字の大きさが制約を受けるため、これらの文字の視認性が不十分となる。使用頻度の高い大文字や数字がこのような制約を受けると、文字列全体の視認性も不十分なものとなる。 When a character is engraved by an engraving apparatus typified by the apparatus described in Patent Document 1, a character pattern is represented by the arrangement of dots on a matrix. Further, when a character is imprinted, a pattern in which the character is underlined may be imprinted.
At that time, for example, if the character to be imprinted is alphanumeric, it is necessary to consider the balance of the appearance of the character string formed by the imprinted character, and it may be underlined. It is also necessary to consider. For this reason, as shown in FIG. 15, for uppercase letters and numbers, patterns are set such that the center is higher than the lowercase letters and dots are not arranged in the bottom row of the matrix.
However, when the pattern as shown in FIG. 15 is used, the size of capital letters and numbers is restricted, and the visibility of these characters becomes insufficient. When capital letters and numbers that are frequently used are subject to such restrictions, the visibility of the entire character string becomes insufficient.
　本発明は、上述の事情の下になされたもので、文字列中で使用頻度の高い文字を視認性よく印字するためのパターン設定装置、パターン設定方法及びプログラムを提供することを目的とする。 The present invention has been made under the above circumstances, and an object thereof is to provide a pattern setting device, a pattern setting method, and a program for printing a frequently used character in a character string with high visibility.
　上記目的を達成するため、本願の第１の発明に係るパターン設定装置は、
　マトリクス上のドットの配置によりキャラクタのパターンを表すパターンデータを、当該キャラクタと対応付けて記憶するパターン記憶手段と、
　印字されるべきキャラクタを指定する指定データを外部より取得し、当該指定データに対応付けられたパターンデータを、前記パターン記憶手段が記憶しているパターンデータより選択して、選択されたパターンデータを、当該パターンデータが表すパターンの印字を行う外部の印字装置へと出力するパターン選択手段と、を有し、
　前記キャラクタのうち所定のものは拡大対象キャラクタに指定されており、各々の拡大対象キャラクタに対応付けて記憶されているパターンデータは少なくとも２個ずつあり、そのうち少なくとも１個が非拡大パターンを表し、少なくとも１個が拡大パターンを表すものであって、前記拡大パターンにおけるドットは、少なくとも１個が前記非拡大パターンにおけるドットよりも前記マトリクス上の外側よりに配置されている、
　ことを特徴とする。 In order to achieve the above object, a pattern setting apparatus according to the first invention of the present application is provided.
Pattern storage means for storing pattern data representing a character pattern by arranging dots on a matrix in association with the character;
The designation data for designating the character to be printed is acquired from the outside, the pattern data associated with the designation data is selected from the pattern data stored in the pattern storage means, and the selected pattern data is selected. A pattern selection means for outputting to an external printing device for printing the pattern represented by the pattern data,
A predetermined one of the characters is designated as an enlargement target character, and there are at least two pattern data stored in association with each enlargement target character, at least one of which represents a non-enlargement pattern, At least one represents an enlarged pattern, and at least one dot in the enlarged pattern is arranged on the outside of the matrix more than a dot in the non-enlarged pattern,
It is characterized by that.
　このようなパターン設定装置によれば、拡大対象キャラクタについては非拡大パターンよりもサイズの大きい拡大パターンに従ったキャラクタの印字が行われる。このため、拡大対象キャラクタの視認性が十分に確保される。 According to such a pattern setting device, the characters to be enlarged are printed according to the enlarged pattern having a size larger than that of the non-enlarged pattern. For this reason, the visibility of the enlargement target character is sufficiently ensured.
　前記マトリクスは少なくとも３行×３列の大きさを有し、前記拡大パターンにおけるドットは、前記マトリクス上の最上行及び最下行に少なくとも１個ずつ配置されていてもよい。 The matrix may have a size of at least 3 rows × 3 columns, and at least one dot in the enlarged pattern may be arranged on the top row and the bottom row on the matrix.
　各々の拡大対象キャラクタに対応付けて記憶されているパターンデータのうち、非拡大パターンにおけるドットは、前記少なくとも３行×３列の大きさを有するマトリクスの最下行以外の行にのみ配置されていてもよい。
　この場合、前記パターン選択手段は、
　取得した指定データが拡大対象キャラクタを指定しているか否かを判別し、拡大対象キャラクタを指定していると判別したときは、当該指定データが表すキャラクタに下線を付すことを指定するデータを含んでいるか否かを判別し、
　前記取得した指定データが拡大対象キャラクタを指定しており、且つ、当該指定データが表すキャラクタに下線を付すことを指定していないと判別したときは、当該拡大対象キャラクタの拡大パターンを表すパターンデータを選択し、
　前記取得した指定データが、当該指定データが表すキャラクタに下線を付すことを指定していると判別したときは、当該拡大対象キャラクタの非拡大パターンを表すパターンデータを選択し、選択した当該キャラクタのパターンデータが示す非拡大パターンとマトリクスの最下行に下線を表すためのドットを配置したパターンとを合成した結果に相当する下線入りパターンを表すパターンデータを生成し、生成したパターンデータを、選択したパターンデータに代えて前記外部の印字装置へと出力するものであってもよい。 Of the pattern data stored in association with each character to be enlarged, the dots in the non-enlarged pattern are arranged only in rows other than the lowest row of the matrix having the size of at least 3 rows × 3 columns. Also good.
In this case, the pattern selection means
It is determined whether or not the acquired designation data designates an enlargement target character, and when it is judged that the enlargement target character is designated, data that designates that the character represented by the designation data is underlined is included. Whether or not
When it is determined that the acquired designation data designates the enlargement target character and it is not designated to underline the character represented by the designation data, pattern data representing the enlargement pattern of the enlargement target character Select
When it is determined that the acquired designation data designates that the character represented by the designation data is underlined, pattern data representing a non-enlarged pattern of the enlargement target character is selected, and the selected character The pattern data representing the underlined pattern corresponding to the result of combining the non-enlarged pattern indicated by the pattern data and the pattern in which the dot for expressing the underline is arranged at the bottom row of the matrix is generated, and the generated pattern data is selected. Instead of pattern data, the data may be output to the external printing device.
　各々の拡大対象キャラクタに対応付けて記憶されているパターンデータのうち前記非拡大パターンにおけるドットは、前記少なくとも３行×３列の大きさを有するマトリクスの最下行以外の行にのみ配置されており、前記パターン選択手段は、
　過去に取得した指定データが指定している拡大対象キャラクタにつき拡大パターン又は非拡大パターンのいずれを選択したかを示す選択履歴データを生成して記憶する手段を備え、
　新たに取得した指定データが拡大対象キャラクタを指定しているか否かを判別し、拡大対象キャラクタを指定していると判別したときは、当該指定データが表すキャラクタに下線を付すことを指定するデータを含んでいるか否かを判別し、下線を付すことを指定していないと判別したときは、過去に取得した指定データにつき拡大パターン又は非拡大パターンのいずれが選択されていたかを、前記選択履歴データに基づいて判別し、
　過去に取得した指定データにつき拡大パターンが選択されていたと判別したときは、当該拡大対象キャラクタの拡大パターンを表すパターンデータを選択し、その他のときは、当該拡大対象キャラクタの非拡大パターンを表すパターンデータを選択し、
　前記取得した指定データが、当該指定データが表すキャラクタに下線を付すことを指定していると判別したときは、当該拡大対象キャラクタの非拡大パターンを表すパターンデータを選択し、選択した当該キャラクタのパターンデータが示す非拡大パターンとマトリクスの最下行に下線を表すためのドットを配置したパターンとを合成した結果に相当する下線入りパターンを表すパターンデータを生成し、生成したパターンデータを、選択したパターンデータに代えて前記外部の印字装置へと出力するものであってもよい。 Of the pattern data stored in association with each character to be enlarged, the dots in the non-enlarged pattern are arranged only in rows other than the lowest row of the matrix having the size of at least 3 rows × 3 columns. The pattern selection means includes:
Means for generating and storing selection history data indicating whether an enlargement pattern or a non-enlargement pattern has been selected for an enlargement target character designated by designated data acquired in the past,
Data that specifies whether the newly specified data specifies an enlargement target character, and if it is determined that the enlargement target character is specified, specifies that the character represented by the specified data is underlined If it is determined that underlining is not specified, the selection history indicates whether an enlarged pattern or a non-enlarged pattern has been selected for the specified data acquired in the past. Based on the data,
When it is determined that the enlargement pattern has been selected for the specified data acquired in the past, the pattern data representing the enlargement pattern of the enlargement target character is selected, and in other cases, the pattern representing the non-enlargement pattern of the enlargement target character Select the data
When it is determined that the acquired designation data designates that the character represented by the designation data is underlined, pattern data representing a non-enlarged pattern of the enlargement target character is selected, and the selected character The pattern data representing the underlined pattern corresponding to the result of combining the non-enlarged pattern indicated by the pattern data and the pattern in which the dot for expressing the underline is arranged at the bottom row of the matrix is generated, and the generated pattern data is selected. Instead of pattern data, the data may be output to the external printing device.
　このような構成によれば、下線が、キャラクタのなす文字列の全体に及ばない場合、下線がない部分の拡大対象キャラクタも非拡大パターンにより印字される。このため、下線部が部分的に含まれている文字列については、拡大対象キャラクタの視認性よりも文字列全体の外観上のバランスが優先された態様で文字列の形成が行われる。 According to such a configuration, when the underline does not reach the entire character string formed by the character, the enlargement target character in the portion without the underline is also printed with the non-enlargement pattern. For this reason, for a character string partially including the underlined portion, the character string is formed in a manner in which the balance of the appearance of the entire character string is prioritized over the visibility of the enlargement target character.
　また、本願の第２の発明に係るパターン設定方法は、
　マトリクス上のドットの配置によりキャラクタのパターンを表すパターンデータを、当該キャラクタと対応付けて記憶するパターン記憶ステップと、
　印字されるべきキャラクタを指定する指定データを外部より取得し、当該指定データに対応付けられたパターンデータを、前記パターン記憶ステップで記憶しているパターンデータより選択して、選択されたパターンデータを、当該パターンデータが表すパターンの印字を行う外部の印字装置へと出力するパターン選択ステップと、を有し、
　前記キャラクタのうち所定のものは拡大対象キャラクタに指定されており、各々の拡大対象キャラクタに対応付けて記憶されているパターンデータは少なくとも２個ずつあり、そのうち少なくとも１個が非拡大パターンを表し、少なくとも１個が拡大パターンを表すものであって、前記拡大パターンにおけるドットは、少なくとも１個が前記非拡大パターンにおけるドットよりも前記マトリクス上の外側よりに配置されている、
　ことを特徴とする。 The pattern setting method according to the second invention of the present application is

The designation data for designating the character to be printed is acquired from outside, the pattern data associated with the designation data is selected from the pattern data stored in the pattern storage step, and the selected pattern data is selected.

It is characterized by that.
　このようなパターン設定方法によっても、拡大対象キャラクタについては非拡大パターンよりもサイズの大きい拡大パターンに従ったキャラクタの印字が行われる。このため、拡大対象キャラクタの視認性が十分に確保される。 Even with such a pattern setting method, characters that are to be enlarged are printed according to an enlarged pattern having a size larger than that of the non-enlarged pattern. For this reason, the visibility of the enlargement target character is sufficiently ensured.

　以下、本発明の実施形態に係る打刻ユニット２０のヘッド３０を図面を参照して説明する。図４は、本実施形態に係る打刻ユニット２０のヘッド３０の断面図であり、ケーシング３１の中心を通りＸＺ平面に平行する断面を示す図である。なお、図４ではケーシング３１のレバーホルダ天板３１ｂと、ケーシング３１と保持部材３２とを固定する固定ばね３１ｃと、は省略している。打刻ピン３３の－Ｚ側端部は下方に向かって細くなる円錐状、或いは球状に整形されている。また＋Ｚ側端部には、他の部分よりも経が大きい大径部３３ａが形成されている。そして、－Ｚ側端部が保持部材３２から突き出た状態で、Ｚ軸に沿って移動可能に保持されている。 Hereinafter, the head 30 of the embossing unit 20 according to the embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a cross-sectional view of the head 30 of the embossing unit 20 according to this embodiment, and shows a cross-section passing through the center of the casing 31 and parallel to the XZ plane. In FIG. 4, the lever holder top plate 31 b of the casing 31 and the fixing spring 31 c that fixes the casing 31 and the holding member 32 are omitted. The −Z side end portion of the stamping pin 33 is shaped into a conical shape or a spherical shape that narrows downward. A large-diameter portion 33a having a larger warp than other portions is formed at the + Z side end portion. Then, with the −Z side end protruding from the holding member 32, it is held movably along the Z axis.
　本実施形態に係る打刻ユニット２０のヘッド３０は、保持部材３２と、打刻ピン３３と、復帰ばね１１３と、打刻ピン駆動レバー１１４と、可動ヨーク１１６と、ヨークケース１１７と、ヨークプレート１１８と、駆動コイル４３と、を備える。 The head 30 of the stamping unit 20 according to the present embodiment includes a holding member 32, a stamping pin 33, a return spring 113, a stamping pin drive lever 114, a movable yoke 116, a yoke case 117, and a yoke plate. 118 and a drive coil 43.
　打刻ピン駆動レバー１１４、可動ヨーク１１６、駆動コイル４３により、打刻ピン３３を駆動するアクチュエータ４０が構成される。 The stamping pin drive lever 114, the movable yoke 116, and the drive coil 43 constitute an actuator 40 that drives the stamping pin 33.
　ヨークケース１１７、ヨークプレート１１８は、９つのアクチュエータ４０を収容するケーシング３１を構成する。 The yoke case 117 and the yoke plate 118 constitute a casing 31 that accommodates the nine actuators 40.
　保持部材３２は、その内部に打刻ピン３３および打刻ピンガイド板１１５ａ～１１５ｄを収納している。この比較的長尺となる打刻ピン３３は、打刻ピンガイド板１１５ａ～１１５ｄによって、保持部材３２内において概ね一定の姿勢を維持する。打刻ピンガイド板１１５ａ～１１５ｄは板体にガイドとなる穴を貫通させたものであり、このガイド穴に打刻ピンを通すことで打刻ピンの姿勢を維持している。 The holding member 32 accommodates the stamping pin 33 and the stamping pin guide plates 115 a to 115 d therein. The relatively long stamping pin 33 maintains a substantially constant posture in the holding member 32 by the stamping pin guide plates 115 a to 115 d . The stamping pin guide plates 115 a to 115 d are formed by penetrating a hole serving as a guide through the plate body, and the posture of the stamping pin is maintained by passing the stamping pin through the guide hole.
　復帰ばね１１３は、打刻ピン３３を＋Ｚ方向に付勢するためのものであり、コイルスプリングからなり、それぞれに打刻ピン３３が挿入される。 The return spring 113 is for urging the stamping pin 33 in the + Z direction, and is composed of a coil spring, and the stamping pin 33 is inserted into each of the coil springs.
　打刻ピン駆動レバー１１４は、打刻ピン３３それぞれを待機位置から－Ｚ側（下方）に移動させるためのものである。打刻ピン駆動レバー１１４には、軟磁性体からなる可動ヨーク１１６が、例えばカシメ加工により一体に固定されている。可動ヨーク１１６は、円柱形状を有している。 The stamping pin drive lever 114 is for moving each of the stamping pins 33 from the standby position to the −Z side (downward). A movable yoke 116 made of a soft magnetic material is integrally fixed to the stamping pin drive lever 114 by caulking, for example. The movable yoke 116 has a cylindrical shape.
　打刻ピン３３は復帰ばね１１３により、＋Ｚ方向に付勢される。そして、打刻ピン３３の大径部３３ａが打刻ピン駆動レバーと当接することで、それ以上の＋Ｚ方向への移動を規制されている。この位置が打刻ピン３３の待機位置である。 The stamping pin 33 is urged in the + Z direction by the return spring 113. Further, since the large-diameter portion 33a of the stamping pin 33 is in contact with the stamping pin drive lever, further movement in the + Z direction is restricted. This position is the standby position for the marking pin 33.
　打刻ピン駆動レバー１１４は、レバーホルダ３１ａ内において、打刻ピン駆動レバー１１４の打刻ピン３３の大径部３３ａとの当接部(先端)と反対側の端部（後端）は図示しない保持機構によって保持されている。これによって、打刻ピン駆動レバー１１４はＺ軸方向に揺動することが可能である。なお、保持機構は、例えばレバーホルダ３１ａの天板であるレバーホルダ天板３１ｂと、打刻ピン駆動レバー１１４の端部との間に板ばねを設ける等して構成される。 In the lever holder 31a, the stamping pin drive lever 114 has an end portion (rear end) opposite to a contact portion (front end) with the large diameter portion 33a of the stamping pin 33 of the stamping pin drive lever 114. Not held by the holding mechanism. Thereby, the stamping pin drive lever 114 can swing in the Z-axis direction. The holding mechanism is configured, for example, by providing a leaf spring between the lever holder top plate 31b, which is the top plate of the lever holder 31a, and the end of the stamping pin drive lever 114.
　ヨークケース１１７は、可動ヨーク１１６を引きつけて打刻ピン駆動レバー１１４を待機位置から－Ｚ方向（下方）へ駆動するためのものである。ヨークケース１１７は、例えば、電磁軟鉄や珪素鋼等などの軟磁性体からなる。ヨークケース１１７は、保持部材３２上に保持される。ヨークケース１１７には、可動ヨーク１１６が配される位置に対応して円柱形状のコアが設けられている。この円柱形状のコアを中心として、駆動コイル４３が設けられる。 The yoke case 117 is for attracting the movable yoke 116 to drive the embossing pin drive lever 114 in the −Z direction (downward) from the standby position. The yoke case 117 is made of a soft magnetic material such as electromagnetic soft iron or silicon steel. The yoke case 117 is held on the holding member 32. The yoke case 117 is provided with a cylindrical core corresponding to the position where the movable yoke 116 is disposed. A drive coil 43 is provided around the cylindrical core.
　ヨークプレート１１８は、閉じた磁路を形成するためのものであり、例えば、電磁軟鉄や珪素鋼等などの軟磁性体からなる。 The yoke plate 118 is for forming a closed magnetic path, and is made of a soft magnetic material such as electromagnetic soft iron or silicon steel.
　駆動コイル４３は、電流の供給を受けて、ヨークケース１１７とヨークプレート１１８とを磁化するためのものである。ヨークケース１１７とヨークプレート１１８とが磁化されると、可動ヨーク１１６が引き付けられるため、打刻ピン駆動レバー１１４先端は－Ｚ方向へ揺動する。打刻ピン駆動レバー１１４先端が－Ｚ方向に揺動するのに伴って、打刻ピン３３も－Ｚ方向に移動する。 The drive coil 43 is for magnetizing the yoke case 117 and the yoke plate 118 upon receiving a current supply. When the yoke case 117 and the yoke plate 118 are magnetized, the movable yoke 116 is attracted, so that the tip of the stamping pin drive lever 114 swings in the −Z direction. As the tip of the stamping pin drive lever 114 swings in the −Z direction, the stamping pin 33 also moves in the −Z direction.
　駆動コイル４３への電流の供給が中断されると、打刻ピン３３を＋Ｚ方向に付勢している復帰ばね１１３により、打刻ピン３３および打刻ピン駆動レバー１１４は待機位置に復帰する。 When the supply of current to the drive coil 43 is interrupted, the stamping pin 33 and the stamping pin drive lever 114 are returned to the standby position by the return spring 113 urging the stamping pin 33 in the + Z direction.
　図５は、９本の打刻ピン３３の配置を示す斜視図である。図５に示されるように、９本の打刻ピン３３それぞれは、＋Ｚ側端がＺ軸に平行な鉛直軸Ｌを中心とする円Ｃ１に沿って位置した状態で、保持部材３２によって保持されている。また、打刻ピン３３をそれぞれ駆動する打刻ピン駆動レバー１１４および駆動コイル４３も、鉛直軸Ｌからの距離が相互に等しくなるように配置されている。 FIG. 5 is a perspective view showing the arrangement of nine embossing pins 33. As shown in FIG. 5, each of the nine punching pins 33 is held by the holding member 32 in a state where the + Z side end is located along a circle C <b> 1 centering on the vertical axis L parallel to the Z axis. ing. Further, the embossing pin drive lever 114 and the drive coil 43 that respectively drive the embossing pins 33 are also arranged so that the distances from the vertical axis L are equal to each other.
　また、図６に示すように打刻ピン３３は、打刻ピン３３の中心軸と鉛直軸Ｌとの成す角度θが９つの打刻ピン３３にわたって相互に等しくなるように配置される。なお、角度θは、作図の便宜上、図６では鉛直軸Ｌに平行な線ｌと打刻ピン３３の中心軸とのなす角度θとして示している。本実施形態では図６に示されるように、打刻ピン３３それぞれの下端は、鉛直軸Ｌ上に中心を有し半径が円Ｃ１よりも小さい円Ｃ２上に位置するように配置されている。 Further, as shown in FIG. 6, the stamping pins 33 are arranged so that the angle θ formed by the center axis of the stamping pins 33 and the vertical axis L is equal to each other over the nine stamping pins 33. For convenience of drawing, the angle θ is shown as an angle θ formed by the line l parallel to the vertical axis L and the central axis of the stamping pin 33 in FIG. In the present embodiment, as shown in FIG. 6, the lower ends of the embossing pins 33 are arranged so as to be located on a circle C2 having a center on the vertical axis L and a radius smaller than the circle C1.
　図７は、打刻ピン３３それぞれの下端（対象物に当接する端）の配置を示す図である。本実施形態では、図７を参照するとわかるように、打刻ピン３３それぞれの下端は、ＸＹ面における円Ｃ２上に位置するとともに、Ｙ軸方向に関して距離ｄずつ離間するように配置されている。この距離ｄは、解像度を２００ｄｐｉとするパターンを構成するドットＤ２の径の２倍の距離に概ね相当し、解像度を３００ｄｐｉとするパターンを構成するドットＤ３の径の３倍の距離に概ね相当する。以下、９本の打刻ピン３３について、最も－Ｙ側にある打刻ピン３３を打刻ピン３３１と表示し、＋Ｙ方向に向かってそれぞれの打刻ピン３３を打刻ピン３３２、３３３、…３３９とも表示する。 FIG. 7 is a diagram showing the arrangement of the lower ends (ends contacting the object) of the embossing pins 33. In the present embodiment, as can be seen with reference to FIG. 7, the lower ends of the embossing pins 33 are located on a circle C2 in the XY plane and are arranged so as to be separated by a distance d in the Y-axis direction. This distance d substantially corresponds to a distance twice as large as the diameter of the dot D2 constituting the pattern having a resolution of 200 dpi, and roughly corresponds to a distance three times as large as the diameter of the dot D3 constituting the pattern having a resolution of 300 dpi. . Hereinafter, the nine embossing pins 33, the most -Y in side embossing pins 33 displays the embossing pins 33 1, + Y embossing pins 33 2 each embossing pins 33 in a direction, 33 3, ... 33 9 both to display.
　図８は、打刻ユニット２０のブロック図である。前記ドライバ２６は、ベース部材２１に形成された第２部分２１ｂの＋Ｙ側に配置され、Ｘモータ５０Ｘ、Ｙモータ５０Ｙ、及びヘッド３０と電気的に接続されている。そして、図８を参照するとわかるように、ＣＰＵ１１の指示に基づいて、Ｘモータ５０Ｘ及びＹモータ５０Ｙを駆動して、ヘッド３０をＸ軸方向及びＹ軸方向へ移動する。また、ヘッド３０の打刻ピン３３１～３３９を駆動するアクチュエータ４０１～４０９それぞれの駆動コイル４３にパルス信号を供給する。 FIG. 8 is a block diagram of the stamping unit 20. The driver 26 is disposed on the + Y side of the second portion 21 b formed on the base member 21 and is electrically connected to the X motor 50 </ b> X, the Y motor 50 </ b> Y, and the head 30. Then, as can be seen with reference to FIG. 8, the X motor 50X and the Y motor 50Y are driven based on the instruction of the CPU 11 to move the head 30 in the X axis direction and the Y axis direction. In addition, a pulse signal is supplied to the drive coils 43 of the actuators 40 1 to 40 9 that drive the marking pins 33 1 to 33 9 of the head 30.
　図９Ａには、ドライバ２６が、アクチュエータ４０１～４０９それぞれの駆動コイル４３に供給するパルス信号Ｐ２及びパルス信号Ｐ３が示されている。パルス信号Ｐ２は、対象物に解像度を２００ｄｐｉとするパターンを構成するドットを打刻するための電圧信号の１例である。また、パルス信号Ｐ３は、対象物に解像度を３００ｄｐｉとするパターンを構成するドットを打刻するための電圧信号の１例である。また、パルス信号Ｐ２は、最大電圧がＶ２であり、パルス幅がＴの矩形波である。一方、パルス信号Ｐ３は、最大電圧がＶ２よりも小さいＶ３であり、パルス幅がＴの矩形波である。 FIG. 9A shows a pulse signal P2 and a pulse signal P3 that the driver 26 supplies to the drive coils 43 of the actuators 40 1 to 40 9 . The pulse signal P2 is an example of a voltage signal for imprinting dots constituting a pattern with a resolution of 200 dpi on the object. The pulse signal P3 is an example of a voltage signal for imprinting dots constituting a pattern with a resolution of 300 dpi on the object. The pulse signal P2 is a rectangular wave having a maximum voltage of V2 and a pulse width of T. On the other hand, the pulse signal P3 is a rectangular wave having a maximum voltage V3 smaller than V2 and a pulse width T.
　一例として、図９Ｂには、打刻ピン３３の、待機位置Ｄ０からの変位と時間との関係を示す曲線Ｓ２及び曲線Ｓ３が示されている。曲線Ｓ２は、アクチュエータ４０にパルス信号Ｐ２が供給されたときの打刻ピン３３の変位と時間との関係を示す曲線である。また、曲線Ｓ３は、アクチュエータ４０にパルス信号Ｐ３が供給されたときの打刻ピン３３の変位と時間との関係を示す曲線である。 As an example, FIG. 9B, the embossing pins 33, curves S2 and a curve S3 shows the relationship between the displacement and the time from the standby position D 0 is shown. A curve S2 is a curve showing the relationship between the displacement of the stamping pin 33 and the time when the pulse signal P2 is supplied to the actuator 40. A curve S3 is a curve showing the relationship between the displacement of the stamping pin 33 and the time when the pulse signal P3 is supplied to the actuator 40.
　曲線Ｓ２と曲線Ｓ３とを見るとわかるように、打刻ピン３３はパルス信号がハイレベルとなる時刻ｔ１から少し遅れて移動を開始する。移動を開始した打刻ピン３３は、パルス信号がローレベルとなる時刻ｔ２までの間に加速され、パルス信号がローレベルとなった後も移動を継続し、変位がＤＴとなる対象物に当接する位置に達する。そして、しばらくその位置に留まった後に変位がＤ０となる待機位置まで戻る。 As can be seen from the curves S2 and S3, the embossing pin 33 starts moving with a slight delay from the time t1 when the pulse signal becomes high level. The stamping pin 33 that has started to move is accelerated until time t2 when the pulse signal becomes low level, and continues to move even after the pulse signal becomes low level, so that the displacement becomes DT. Reach the abutting position. Then, the flow returns to the standby position which is displaced after remained in that position while the D 0.
　本実施形態においては、パルス信号Ｐ２によって得られるドット径が、２００ｄｐｉのパターンを形成するためのドット径である。また、パルス信号Ｐ３によって得られるドット径が、３００ｄｐｉのパターンを形成するためのドット径となるように設定されている。 In this embodiment, the dot diameter obtained by the pulse signal P2 is a dot diameter for forming a 200 dpi pattern. Further, the dot diameter obtained by the pulse signal P3 is set to be a dot diameter for forming a 300 dpi pattern.
　ドライバ２６は、ＣＰＵ１１からの指示により、最大電圧値及びパルス幅がそれぞれ異なるパルス信号Ｐ２、及びパルス信号Ｐ３を選択的にアクチュエータ４０１～４０９それぞれに供給する。これにより、対象物に当接するときの打刻ピン３３１～３３９の速度が解像度に見合った速度となる。そして、対象物に、解像度が３００ｄｐｉのパターンを構成するドットと、解像度２００ｄｐｉのパターンを構成するドットとを選択的に打刻することができる。 In response to an instruction from the CPU 11, the driver 26 selectively supplies a pulse signal P2 and a pulse signal P3 having different maximum voltage values and pulse widths to the actuators 40 1 to 40 9 respectively. As a result, the speed of the embossing pins 33 1 to 33 9 when coming into contact with the object becomes a speed commensurate with the resolution. Then, dots that form a pattern with a resolution of 300 dpi and dots that form a pattern with a resolution of 200 dpi can be selectively imprinted on the object.
　上述のように構成された打刻ユニット２０は、図１０を参照するとわかるように、ベース部材２１の上面がほぼ水平となった状態で、例えばベルトコンベア１２０の上方にヘッド３０が位置するように不図示の支持部材によって支持されている。また、本実施形態では、ベルトコンベア１２０に載置された対象物１００の上面は、打刻ピン３３の待機位置と打刻限界位置との間に位置した状態となっている。 The stamping unit 20 configured as described above is configured such that the head 30 is positioned above the belt conveyor 120, for example, with the upper surface of the base member 21 being substantially horizontal, as can be seen with reference to FIG. It is supported by a support member (not shown). Further, in the present embodiment, the upper surface of the object 100 placed on the belt conveyor 120 is in a state located between the standby position of the stamping pin 33 and the stamping limit position.

In the present embodiment, an external device such as a personal computer is connected to the interface 16. Information about characters formed on the object 100 is notified to the CPU 11 via the interface 16 and the system bus 10a.
　対象物１００に形成する文字に関する情報は、具体的には、例えば当該文字のキャラクタコード、当該文字が含まれるべき文字列が横書きであるとして当該文字が下線付きであるか否かを示すデータからなっている。 Specifically, the information about the character formed on the object 100 is, for example, from the character code of the character, data indicating whether the character string that should contain the character is horizontal writing, and whether the character is underlined. It has become.
　前記ＣＰＵ１１は、補助記憶部１３に記憶されたプログラムなどを読み出して、このプログラムに従って、打刻ユニット２０などの各部を統括的に制御する。 The CPU 11 reads a program stored in the auxiliary storage unit 13 and controls each unit such as the embossing unit 20 according to the program.
　次に、上述のように構成された打刻装置１０の動作について説明する。前提として、対象物１００は、図１０に示されるように、打刻ユニット２０の下方に搬送され、ＣＰＵ１１によって検出部１５を介して検出されているものとする。また、本実施形態では、一例として英文字「Ａ」「Ｂ」「Ｃ」「ｐ」「ｑ」「ｒ」を、図１１に示すような９行９列のマトリクスＭ上に、打刻して形成するものとする。 Next, the operation of the engraving apparatus 10 configured as described above will be described. As a premise, it is assumed that the object 100 is conveyed below the embossing unit 20 and detected by the CPU 11 via the detection unit 15 as shown in FIG. In this embodiment, as an example, English letters “A”, “B”, “C”, “p”, “q”, and “r” are imprinted on a matrix M of 9 rows and 9 columns as shown in FIG. Shall be formed.
　まず、ＣＰＵ１１は、外部装置などから文字に関する情報が供給されると、この管理情報から対象物１００に形成するこの文字の文字パターンを設定する。文字パターンの設定は、例えば、補助記憶部１３が予め文字パターンを表す文字パターンデータを、当該文字パターンが表す文字のキャラクタコードに対応付けて記憶する。そして、ＣＰＵ１１がこれらの文字パターンデータのうちから、文字に関する情報に含まれるキャラクタコードに対応付けられているものを選択することにより行う。 First, when information about characters is supplied from an external device or the like, the CPU 11 sets a character pattern of the characters formed on the object 100 from the management information. For example, the auxiliary storage unit 13 stores character pattern data representing a character pattern in association with the character code of the character represented by the character pattern. And CPU11 performs by selecting the thing matched with the character code contained in the information regarding a character among these character pattern data.
　文字パターンデータは、例えば図１２に示すような、上述のマトリクスＭ上のドットの配置により文字パターンを表すデータである（なお、図１２、図１３Ａ及び図１３Ｂにおいては、「●」がドットを示す）。 The character pattern data is data representing a character pattern by the dot arrangement on the matrix M as shown in FIG. 12, for example (in FIG. 12, FIG. 13A and FIG. 13B, “●” indicates a dot). Show).
　所定の文字（以下、拡大対象文字と呼ぶ）のキャラクタコードには、図１２に示すようにマトリクスＭの最下行及び最上行に必ずドットが分布する形をとる文字パターン（以下、「拡大文字パターン」と呼ぶ）を表す拡大文字パターンデータと、図１５に示すようにマトリクスＭの最下行にはドットが分布しない文字パターン（以下、「通常文字パターン」と呼ぶ）を表す通常文字パターンデータとが対応付けられているものとする。なお、図１２、図１３Ａ及び図１３Ｂは、文字「Ａ」「Ｂ」及び「Ｃ」が拡大対象文字であって文字「ｐ」「ｑ」及び「ｒ」が拡大対象文字でない場合を例示している。 As shown in FIG. 12, the character code of a predetermined character (hereinafter referred to as a character to be enlarged) has a character pattern (hereinafter referred to as an “enlarged character pattern”) in which dots are always distributed in the bottom row and the top row of the matrix M. ) And normal character pattern data representing a character pattern in which dots are not distributed in the bottom row of the matrix M (hereinafter referred to as “normal character pattern”) as shown in FIG. Assume that they are associated. 12, 13A, and 13B exemplify the case where the characters “A”, “B”, and “C” are the characters to be expanded, and the characters “p”, “q”, and “r” are not the characters to be expanded. ing.
　拡大対象文字は、例えば、使用頻度が高く視認性を確保する必要性が高いか、といった観点から予め人為的に選別された文字であればよい。また、補助記憶部１３は、当該拡大対象文字のキャラクタコード群を予め記憶するものである。そして、ＣＰＵ１１は、補助記憶部１３にアクセスしてこのキャラクタコード群を参照することにより、対象物１００に形成すべき文字が拡大対象文字であるか否かを判別すればよい。 The character to be expanded may be a character that has been artificially selected in advance from the viewpoint of, for example, whether it is frequently used and it is highly necessary to ensure visibility. The auxiliary storage unit 13 stores a character code group of the character to be enlarged in advance. And CPU11 should just determine whether the character which should be formed in the target object 100 is an expansion object character by accessing the auxiliary | assistant memory | storage part 13 and referring this character code group.
　ＣＰＵ１１は、拡大対象文字の文字パターンを通常文字パターンとするか拡大文字パターンとするかの決定、及び文字パターンデータの選択を、例えば、以下（１）～（４）として示す手順により決定する。
（１）　文字に関する情報を新たに取得し、この情報に含まれるキャラクタコードが拡大対象文字を示すものか否かを判別する。拡大対象文字を示すものでないと判別したときは、当該キャラクタコードに対応付けられている文字パターンデータを選択する。
（２）　拡大対象文字を示すと（１）で判別したときは、（１）で取得した情報が、下線を付すことを指定するものか否かを判別する。下線を付すことを指定していると判別したときは、（１）で取得した情報に含まれるキャラクタコードに対応付けられている通常文字パターンデータを選択する。
（３）　下線を付すことを指定していないと（２）で判別したときは、過去に情報を取得した拡大対象文字につき拡大文字パターン又は通常文字パターンのいずれを選択したかを判別する。この判別は、例えば、当該選択を行うたびに当該選択の結果を示す選択履歴データを生成して補助記憶部１３に記憶させ、この選択履歴データに基づいて行うようにすればよい。なお、どの範囲の過去の選択履歴データを判別に用いるかは任意であり、例えば、対象物１００にすでに形成した文字についての選択履歴データすべてを判別に用いてもよい。また、形成しようとする文字と共通する行に属する文字についての選択履歴データのみを用いてもよい。
（４）　過去に情報を取得した拡大対象文字につき拡大文字パターンが選択されていたと判別したときは、（１）で取得した情報に含まれるキャラクタコードに対応付けられている拡大文字パターンデータを選択する。通常文字パターンが選択されていたと判別したときは、（１）で取得した情報に含まれるキャラクタコードに対応付けられている通常文字パターンデータを選択する。 The CPU 11 determines whether the character pattern of the character to be enlarged is a normal character pattern or an enlarged character pattern, and the selection of character pattern data, for example, according to the following procedures (1) to (4).
(1) Information on characters is newly acquired, and it is determined whether or not the character code included in the information indicates a character to be enlarged. When it is determined that the character to be enlarged is not indicated, the character pattern data associated with the character code is selected.
(2) When an enlargement target character is indicated, when it is determined in (1), it is determined whether or not the information acquired in (1) specifies underlining. When it is determined that the underline is specified, normal character pattern data associated with the character code included in the information acquired in (1) is selected.
(3) If it is determined in (2) that the underline is not designated, it is determined whether an enlarged character pattern or a normal character pattern has been selected for the enlargement target character for which information has been acquired in the past. This determination may be performed based on the selection history data, for example, by generating selection history data indicating the result of the selection every time the selection is performed and storing the selection history data in the auxiliary storage unit 13. Note that it is arbitrary which range of past selection history data is used for discrimination. For example, all selection history data for characters already formed on the object 100 may be used for discrimination. Alternatively, only the selection history data for characters belonging to the same line as the character to be formed may be used.
(4) When it is determined that an enlarged character pattern has been selected for the enlargement target character whose information has been acquired in the past, the enlarged character pattern data associated with the character code included in the information obtained in (1) is selected. To do. When it is determined that the normal character pattern has been selected, the normal character pattern data associated with the character code included in the information acquired in (1) is selected.
　次に、ＣＰＵ１１が、打刻ユニット３０を制御して、生成した文字を対象物１００の上面に打刻する動作を説明する。図７に示すように、本実施形態においては、打刻ピン３３１～３３９は、Ｙ軸方向に関して距離ｄずつ離間するように配置されている。この距離ｄは１／１００インチである。 Next, an operation in which the CPU 11 controls the stamping unit 30 to stamp the generated character on the upper surface of the object 100 will be described. As shown in FIG. 7, in this embodiment, the embossing pins 33 1 to 33 9 are arranged so as to be separated by a distance d with respect to the Y-axis direction. This distance d is 1/100 inch.
　ＣＰＵ１１は、ヘッド３０を移動させて、対象物１００の上面の文字を打刻するべき位置にヘッド３０を位置決めする。そして、この状態で打刻ピン３３1～３３９のうちで、図１１に示すマトリクスＭの１列目において、文字を生成するのに必要なドットに相当する打刻ピンを駆動させてドットを打刻する。 The CPU 11 moves the head 30 to position the head 30 at a position where the characters on the upper surface of the object 100 are to be engraved. Then, among the embossing pins 33 1-33 9 in this state, in the first column of the matrix M shown in FIG. 11, the dots by driving the embossing pins corresponding to required dot to generate a character Imprint.
　マトリクスＭの１列目の打刻が完了すると、ＣＰＵ１１は、ヘッド３０を－Ｘ方向に移動させ、マトリクスＭの２列目に位置決めする。なお、この場合のマトリクスＭの各列間の距離は１／１００とする。そして、この状態で打刻ピン３３1～３３９のうちで、図１１に示すマトリクスＭの２列目において、文字を生成するのに必要なドットに相当する打刻ピンを駆動させてドットを打刻する。 When the marking of the first column of the matrix M is completed, the CPU 11 moves the head 30 in the −X direction and positions the second column of the matrix M. In this case, the distance between each column of the matrix M is 1/100. Then, among the embossing pins 33 1-33 9 in this state, in the second column of the matrix M shown in FIG. 11, the dots by driving the embossing pins corresponding to required dot to generate a character Imprint.
　以下、これを繰り返して、９列全てを打刻すると、１文字分の打刻が完了する。さらにＸ方向に文字を生成する必要がある場合には、上述した動作を繰り返して必要なだけ文字を生成する。このようにして、文字を生成すると、文字列が１行完成する。 Hereafter, if this is repeated and all 9 rows are engraved, the engraving for one character is completed. Further, when it is necessary to generate characters in the X direction, the above-described operation is repeated to generate as many characters as necessary. When characters are generated in this way, one line of character string is completed.
　さらに、２行目の文字列を生成する場合には、ＣＰＵ１１は、ヘッド３０をＸＹ方向に移動させて、２行目の最初の文字を打刻する位置にヘッド３０を位置決めして、上述した動作を繰り返すことで、２行目の文字を生成する。 Further, when generating the character string on the second line, the CPU 11 moves the head 30 in the X and Y directions to position the head 30 at the position where the first character on the second line is imprinted. The character on the second line is generated by repeating the operation.
　上述の動作の結果、文字を構成する全てのドットを打刻すると、ＣＰＵ１１は、対象物１００に対する文字の生成を完了させ、処理を終了する。 As a result of the above-described operation, when all the dots constituting the character are engraved, the CPU 11 completes the generation of the character for the object 100 and ends the process.
　このようにして形成される１文字の解像度は１００ｄｐｉである。従って、隣り合うドットの中心から中心までの寸法は０．２５４ｍｍである。従来の文字パターンは、図１５に示すように、高さ方向は７ドットで文字が構成されているので、文字の高さ方向のドットの中心からドットの中心までの寸法は１．５２４ｍｍとなる。 The resolution of one character formed in this way is 100 dpi. Therefore, the dimension from the center of adjacent dots to the center is 0.254 mm. In the conventional character pattern, as shown in FIG. 15, since the character is composed of 7 dots in the height direction, the dimension from the center of the dot in the height direction of the character to the center of the dot is 1.524 mm. .
　一方、本実施形態によれば所定の文字は拡大対象文字に指定されており、拡大パターンにおけるドットは、マトリクスＭの最下行及び最上行のそれぞれに少なくとも１個ずつ配置されている。従って、拡大パターンによれば最大９×９ドットで文字が構成されるので文字高さは最大で２．０３２ｍｍとなり、従来の文字パターンに比べて視認性が向上する。 On the other hand, according to the present embodiment, the predetermined character is designated as the character to be enlarged, and at least one dot in the enlarged pattern is arranged in each of the lowermost row and the uppermost row of the matrix M. Therefore, according to the enlarged pattern, since the character is composed of a maximum of 9 × 9 dots, the character height is 2.032 mm at the maximum, and the visibility is improved as compared with the conventional character pattern.
　このように、ひとつの文字を生成する場合に、文字の高さ方向のドット数が、ヘッド３０が有する打刻ピンの数を超えないような打刻方法をとるのは高速化のためである。本実施形態において、ひとつの文字を生成する場合に、Ｘ軸方向のみにヘッド３０が移動するだけなので文字を生成する速度が高速化する。 As described above, in order to increase the speed, a single character is generated so that the number of dots in the height direction of the character does not exceed the number of marking pins of the head 30. . In the present embodiment, when generating a single character, the speed of generating the character is increased because the head 30 only moves in the X-axis direction.
　ただし、この場合、文字の高さ方向のサイズは、ヘッド３０に配置されている打刻ピン間の最大の距離を越えることができない。このような場合に従来の文字パターンのようにヘッド３０が有する打刻ピンの全てを使って文字を生成できない場合には、それだけ文字の高さ方向のサイズが小さくなるので視認性は悪くなる。 However, in this case, the size in the height direction of the character cannot exceed the maximum distance between the marking pins arranged on the head 30. In such a case, when a character cannot be generated using all the embossing pins of the head 30 as in the conventional character pattern, the size in the height direction of the character is reduced accordingly, and the visibility is deteriorated.
　これに対して、本実施形態ではヘッド３０が有する打刻ピンの全てを使って文字を生成することで文字の高さ方向のサイズを最大に出来るので、従来よりも視認性を向上させることができる。 On the other hand, in the present embodiment, the size in the height direction of the character can be maximized by generating the character using all of the embossing pins of the head 30, so that the visibility can be improved as compared with the conventional case. it can.
　本発明は、ヘッド３０をＸＹ方向に移動させながら文字を生成するような場合においても有効である。そのような実施例を次に説明する。 The present invention is also effective in the case of generating characters while moving the head 30 in the XY directions. Such an embodiment will now be described.
　３００ｄｐｉで文字を生成する場合について図１４を参照しつつ説明する。なお、図１４においては、打刻ピン３３１～３３９それぞれは、１～９までの番号が割り当てられ、この番号を囲む丸で示されている。また、Ｙ軸方向への移動距離は、１／３００インチをＤとして、このＤを用いて示すものとする。 A case of generating characters at 300 dpi will be described with reference to FIG. In FIG. 14, each of the stamping pins 33 1 to 33 9 is assigned a number from 1 to 9, and is indicated by a circle surrounding this number. Further, the movement distance in the Y-axis direction is indicated by using 1/300 inch as D.
　ＣＰＵ１１は、ヘッド３０を移動させて、図１４に示されるように、マトリクスＭの１行目、４行目、７行目の＋Ｘ側に、打刻ピン３３７～３３９を位置決めする。そして、この状態から、ヘッド３０を－Ｘ方向へ移動させながら、打刻ピン３３７～３３９をそれぞれ駆動して、マトリクスＭの１行目、４行目、７行目に、文字を構成するドットを打刻していく。 The CPU 11 moves the head 30 to position the embossing pins 33 7 to 33 9 on the + X side of the first row, fourth row, and seventh row of the matrix M as shown in FIG. From this state, the marking pins 33 7 to 33 9 are driven while moving the head 30 in the −X direction, and characters are formed in the first, fourth, and seventh rows of the matrix M. I will engrave the dots.
　マトリクスＭの１行目、４行目、７行目の打刻が完了すると、ＣＰＵ１１は、ヘッド３０を距離１０Ｄだけ＋Ｙ方向へ移動させ、マトリクスＭの２行目、５行目、８行目の＋Ｘ側に、打刻ピン３３４～３３6を位置決めする。そして、この状態から、ヘッド３０を－Ｘ方向へ移動させながら、打刻ピン３３４～３３6をそれぞれ駆動して、マトリクスＭの２行目、５行目、８行目に、文字を構成するドットを打刻していく。 When the first row, the fourth row, and the seventh row of the matrix M are completed, the CPU 11 moves the head 30 in the + Y direction by the distance 10D, and the second row, the fifth row, and the eighth row of the matrix M. Position the embossing pins 33 4 to 33 6 on the + X side. From this state, the marking pins 33 4 to 33 6 are driven while moving the head 30 in the −X direction, and characters are formed on the second, fifth, and eighth lines of the matrix M. I will engrave the dots.
　マトリクスＭの２行目、５行目、８行目の打刻が完了すると、ＣＰＵ１１は、ヘッド３０を距離１０Ｄだけ＋Ｙ方向へ移動させ、マトリクスＭの３行目、６行目、９行目の＋Ｘ側に、打刻ピン３３１～３３3を位置決めする。そして、この状態から、ヘッド３０を－Ｘ方向へ移動させながら、打刻ピン３３１～３３3をそれぞれ駆動して、マトリクスＭの３行目、６行目、９行目に、文字を構成するドットを打刻していく。 When the second, fifth, and eighth lines of the matrix M have been imprinted, the CPU 11 moves the head 30 by a distance of 10D in the + Y direction, and the third, sixth, and ninth lines of the matrix M. The stamping pins 33 1 to 33 3 are positioned on the + X side. From this state, the marking pins 33 1 to 33 3 are driven while moving the head 30 in the −X direction to form characters on the third, sixth, and ninth lines of the matrix M. I will engrave the dots.
　上述の動作の結果、マトリクスＭのすべての行について、文字を構成するドットを打刻すると、対象物１００に対する文字の生成が完了し、ＣＰＵ１１は処理を終了する。 As a result of the above-described operation, when the dots constituting the characters are imprinted for all the rows of the matrix M, the generation of characters for the object 100 is completed, and the CPU 11 ends the processing.
　ＣＰＵ１１による打刻ユニット２０の制御は、例えば、選択した文字パターンデータを打刻ユニット２０に供給して行う。ただし、形成すべき文字に下線を付すことが指定されていた場合は、この文字を表すものとして選択した文字パターンデータが示すパターンと、マトリクスＭの最下行に下線を表すためのドットを配置したパターンとを合成した結果に相当する下線入りパターンを表すデータを生成する。そして、生成したこのデータを、選択した文字パターンデータに代えて打刻ユニット２０へと供給するものとする。 The control of the stamping unit 20 by the CPU 11 is performed by supplying the selected character pattern data to the stamping unit 20, for example. However, if it is specified that the character to be formed is underlined, a pattern indicated by the character pattern data selected to represent this character and a dot for expressing the underline in the bottom row of the matrix M are arranged. Data representing an underlined pattern corresponding to the result of combining the pattern is generated. The generated data is supplied to the marking unit 20 in place of the selected character pattern data.
　以上説明したように、本実施形態では、拡大対象文字については、下線を付す場合でなく、且つ、過去に拡大対象文字を通常文字パターンで形成したのでない場合、拡大文字パターンに従った文字の形成を行う。このため、拡大対象文字の視認性が十分に確保される。 As described above, in the present embodiment, the character to be enlarged is not underlined, and if the character to be enlarged has not been formed in the past as a normal character pattern, Form. For this reason, the visibility of the characters to be enlarged is sufficiently ensured.
　以上、本発明の実施形態について説明したが、本発明は上記実施形態によって限定されるものではない。例えば、ＣＰＵ１１は、拡大対象文字の形成は、過去に拡大文字パターンでの文字の形成が行われていたか否かを問わず、下線を付す場合でない限りは拡大文字パターンに従って行うように文字パターンデータの選択を行ってもよい。 As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment. For example, the character pattern data is used so that the CPU 11 forms the enlargement target character according to the enlarged character pattern unless it is underlined regardless of whether or not the character has been formed in the enlarged character pattern in the past. May be selected.
　拡大対象文字について、下線を付す場合でなく、且つ、過去に拡大対象文字を通常文字パターンで形成したのでない場合のみ拡大文字パターンに従った文字の形成を行う実施の形態では、下線が文字列の全体に及ばない場合、例えば図１３Ａに示すように、下線がない部分の拡大対象文字も通常文字パターンにより形成される。このように文字を形成することにより、下線部が部分的に含まれている文字列については、拡大対象文字の視認性よりも文字列全体の外観上のバランスが優先された態様で文字列の形成が行われる。 In the embodiment in which characters are formed according to the enlarged character pattern only when the enlargement target character is not underlined and the enlargement target character has not been formed in the past as a normal character pattern, the underline is a character string. For example, as shown in FIG. 13A, the enlargement target character having no underline is also formed by the normal character pattern. By forming characters in this way, for character strings partially including underlined portions, the character strings are displayed in a manner in which the balance of the appearance of the entire character string is prioritized over the visibility of the character to be enlarged. Formation takes place.
　これに対し、過去に拡大文字パターンでの文字の形成が行われていたか否かを問わず、下線を付す場合でない限りは拡大文字パターンに従って行うように文字パターンデータの選択を行う実施の形態によれば、図１３Ｂに示すように、下線がない部分の拡大対象文字は拡大文字パターンにより形成されることとなり、下線の付されない拡大対象文字の視認性の確保が優先される。 On the other hand, in the embodiment in which character pattern data is selected to be performed according to the enlarged character pattern unless underlined, regardless of whether or not the character has been formed with the enlarged character pattern in the past. Accordingly, as shown in FIG. 13B, the enlargement target character in the portion without the underline is formed by the enlargement character pattern, and priority is given to ensuring the visibility of the enlargement target character without the underline.
　例えば、上記実施形態では、解像度が１００ｄｐｉ及び３００ｄｐｉのパターンを形成する場合について説明したが、これに限らず、対象物に当接するときの打刻ピン３３の速度を制御することで、種々の解像度のパターンを構成するドットを打刻することができる。一般に、対象物に当接するときの打刻ピンの速度とドット径とは比例関係にある。この特性を利用して、打刻ピン３３の速度を制御することで、種々の解像度のパターンを構成するドットを打刻することができる。 For example, in the above-described embodiment, the case where a pattern having a resolution of 100 dpi and 300 dpi is formed has been described. However, the present invention is not limited to this, and various resolutions can be achieved by controlling the speed of the embossing pin 33 when contacting the object. The dots constituting the pattern can be imprinted. In general, the speed of the stamping pin when contacting the object and the dot diameter are in a proportional relationship. By utilizing this characteristic and controlling the speed of the marking pin 33, dots constituting various resolution patterns can be stamped.
　また、本実施形態では、マトリクスとして９行×９列のマトリクスＭを使用したが、これに限らず、マトリクスとしては任意の行数×任意の列数のものを用いることができる。ここで、マトリクスとしては、３行×３列以上の大きさのものが好ましい。 In this embodiment, the matrix M of 9 rows × 9 columns is used as the matrix. However, the matrix is not limited to this, and any matrix having any number of rows × any number of columns can be used. Here, the matrix preferably has a size of 3 rows × 3 columns or more.
　また、本実施形態では、拡大文字パターンのドットを９行×９列のマトリクスＭをフルに使って配置したが、これに限らず、例えば非拡大文字パターンのドットを９行×９列のマトリクスＭのうちの中心よりの６行×６列内に配置し、拡大文字パターンのドットをその外側の８行×８列を使って配置してもよい。 In this embodiment, the dots of the enlarged character pattern are arranged using the 9 × 9 matrix M, but the present invention is not limited to this. For example, the dots of the non-enlarged character pattern are arranged in a 9 × 9 matrix. The dots may be arranged within 6 rows × 6 columns from the center of M, and the dots of the enlarged character pattern may be arranged using the outer 8 rows × 8 columns.
　また、本実施形態では、対象物１００に対してヘッド３０を移動させながら対象物１００にパターンを形成したが、これに限らず、ヘッド３０に対して、対象物１００を移動させてもよい。 In the present embodiment, the pattern is formed on the object 100 while moving the head 30 relative to the object 100. However, the present invention is not limited thereto, and the object 100 may be moved relative to the head 30.
　また、本実施形態に係る打刻ユニット２０では、ヘッド３０を相互に直交するＸ軸方向及びＹ軸方向へ移動させる場合について説明したが、これに限らずヘッド３０は、対象物１００の打刻面に沿って移動可能な構成であればよい。 In the embossing unit 20 according to the present embodiment, the case where the head 30 is moved in the X axis direction and the Y axis direction orthogonal to each other has been described. Any configuration that can move along the surface is acceptable.
　また、打刻ユニット２０は必ずしもダイレクトマーキングを行うものでなくてもよく、紙面に印刷を行うものであってもよい。 Further, the stamping unit 20 does not necessarily perform direct marking, and may perform printing on a paper surface.
　また、本実施形態において、打刻ピン３３のそれぞれは円状に配置されているが、これに限られず、扇状、直線状および千鳥状に配置されていてもよい。 Further, in the present embodiment, each of the embossing pins 33 is arranged in a circular shape, but is not limited thereto, and may be arranged in a fan shape, a linear shape, and a staggered shape.
　また、上記実施形態において打刻装置１０の補助記憶部１３に記憶されているプログラムは、フレキシブルディスク、ＣＤ－ＲＯＭ（Compact Disk Read-Only Memory）、ＤＶＤ（Digital Versatile Disk）、ＭＯ（Magneto-Optical disk）等のコンピュータ読み取り可能な記録媒体に格納して配布し、そのプログラムをインストールすることにより、上述の処理を実行する装置を構成することとしてもよい。 In the above embodiment, the programs stored in the auxiliary storage unit 13 of the engraving apparatus 10 are flexible disk, CD-ROM (Compact Disk Read-Only Memory), DVD (Digital Versatile Disk), MO (Magneto-Optical).

　また、プログラムをインターネット等の通信ネットワーク上の所定のサーバ装置が有するディスク装置等に格納しておき、例えば、搬送波に重畳させて、ダウンロード等するようにしても良い。 Further, the program may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded, for example, superimposed on a carrier wave.
　なお、上述の機能を、ＯＳ（Operating System）が分担して実現する場合又はＯＳとアプリケーションとの協働により実現する場合等には、ＯＳ以外の部分のみを媒体に格納して配布してもよく、また、ダウンロード等しても良い。 When the above functions are realized by sharing an OS (Operating System), or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed.
