Abstract
Description
本発明は、自分の手だけにフィットする自分だけの印鑑を簡単に作製することができる印鑑の製造方法に関するものである。 The present invention relates to a method for manufacturing a seal that can easily produce a seal for oneself that fits only one's hand.
従来から、認印や銀行印などの印鑑が広く使用されており、その形状はほとんどが丸棒や四角柱であった。また、一部であるが丸棒や四角柱の外表面に彫刻等の装飾を施したものもあった。一方、前記丸棒や四角柱では指と接触した場合にしっくりしないとか、滑って使いにくい等の問題があるため、指当て部に窪みを設けて握り易くした印鑑が提案されている（例えば、特許文献１〜特許文献３を参照）。 Heretofore, seals such as seals and bank seals have been widely used, and most of the shapes have been round bars or square poles. In some cases, the outer surfaces of round rods and square poles were partially decorated with sculptures and the like. On the other hand, in the case of the round bar or the square pillar, there is a problem that the finger does not feel good when it comes into contact with the finger, or it is difficult to use because it slips. See Patent Documents 1 to 3).
しかしながら、捺印する時の印鑑の握り方は、例えば、２本指でつまむ人、３本指で握る人、４本指で支える人、あるいは５本の指で包み込む人等、１００人いれば１００通りの握り方がある。そのため、特許文献１〜特許文献３に示されるような指当て部に窪みを設けた印鑑は、握り易いと感じる人もいれば、握りにくいと感じる人もいた。 However, the method of gripping the seal at the time of stamping is 100 if there are 100 people, such as a person holding with two fingers, a person holding with three fingers, a person holding with four fingers, or a person wrapping with five fingers. There is a way of grasping the street. For this reason, there are some people who feel that it is easy to grasp the seal having depressions provided in the finger rests as described in Patent Documents 1 to 3, and others who find it difficult to grasp.
即ち、全ての人に握り易いと感じるような印鑑を数種類の印鑑の提供で解決することは困難であり、全ての人に満足してもらうには、個人個人が注文して一個ずつ作るしか解決法がなかった。しかしながら、注文によって一個一個の印鑑を作るには、多くの費用と時間が必要であり、握り易いと感じるのに近い印鑑を自分専用の印鑑として使うことに妥協しているのが現状であった。
そこで、自分の手だけにフィットする自分だけの印鑑を手軽に短時間で、かつ安価に作製することができる新たな印鑑の製造方法の開発が求められていた。
In other words, it is difficult to solve a seal that is easy for everyone to grasp by providing several types of seals, and the only solution to satisfying everyone is to order and make each one individually. There was no law. However, it takes a lot of money and time to make individual seals by order, and at present it is a compromise to use a seal that is easy to grasp as a personal seal .
Therefore, there has been a demand for the development of a new method for manufacturing a seal that can easily and inexpensively produce a seal that fits only with one's own hands.
本発明は上記のような従来の問題点を解決して、自分の手だけにフィットする自分だけの印鑑を手軽に短時間で、かつ安価に作製することができる印鑑の製造方法を提供することを目的とするものである。 The present invention solves the conventional problems as described above, and provides a method for manufacturing a seal that can easily and inexpensively produce a seal of one's own that fits only one's hand.

図１は、本発明に係る印鑑の製造方法を示す工程図である。図１の工程図に示すように、本発明は基本的には下記の３工程からなるものである。
（１）可塑性を有する材質からなる印鑑型の棒状物を握って指当て位置に窪みを形成する工程
（２）窪みを形成した棒状物を３Ｄスキャンしてデータ化する工程
（３）得られたデータに基づいてデジタル成形機により印材を造形する工程
Preferred embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a process chart showing a method for manufacturing a seal according to the present invention. As shown in the process chart of FIG. 1, the present invention basically comprises the following three steps.
(1) Step of forming a depression at a finger contact position by grasping a seal-shaped rod made of a plastic material (2) Step of 3D-scanning the rod formed with the depression (3) Obtained The process of forming a stamping material with a digital molding machine based on data
以下、各工程について説明する。
可塑性を有する材質からなる印鑑型の棒状物を握って指当て位置に窪みを形成する工程は、自分の手だけにフィットするその人特有の窪みを形成するために、前段階としてその人の指形状に対応した窪みを印鑑型の棒状物の表面に型取りする工程である。即ち、棒状物を直接握ることにより、印鑑型の棒状物の表面にその人特有の指当て位置をトレースするとともに、その人の指形状に対応した窪みを忠実に型取りするものである。
前記印鑑型の棒状物は、可塑性を有する材質からなり前記窪みを忠実に型取りできるものである。例えば、握った時に指の形状に対応して忠実に窪み形状を表現可能な可塑性を有する粘土や石膏質材料や熱可塑性樹脂等からなる。また、棒状物の形状としては一般的な印鑑形状である円柱状や四角柱状のものである。なお、熱可塑性樹脂については型取りするのに加熱して軟化させる工程が必要で、粘土とは異なるため後述する。
Hereinafter, each step will be described.
The step of forming a depression at the finger contact position by gripping a seal-shaped stick made of a plastic material is performed as a pre-stage in order to form a depression unique to the person that fits only his / her hand. This is a step of forming a depression corresponding to the shape on the surface of a seal-shaped bar. That is, by directly grasping the bar-shaped object, the finger-contact position peculiar to the person is traced on the surface of the seal-shaped bar-shaped object, and the depression corresponding to the finger shape of the person is faithfully modeled.
The seal-shaped bar is made of a material having plasticity, and is capable of faithfully molding the depression. For example, it is made of plastic clay, gypsum-based material, thermoplastic resin, or the like having a plastic shape capable of faithfully representing the shape of the depression when grasped. Further, the shape of the rod-shaped object is a columnar or square columnar shape which is a general seal shape. It should be noted that a step of heating and softening the thermoplastic resin is required for molding, which is different from clay, and will be described later.
窪みを形成した棒状物を３Ｄスキャンしてデータ化する工程は、前記窪みを型取りした棒状物を３Ｄスキャナーによりスキャンして外形状を３次元のデジタルデータとして数値化する工程である
前記３Ｄスキャナーは、対象物の凹凸を感知して３Ｄデータとして取り込むための装置であり、対象物にレーザーを照射したり、センサーを当てたりしながら３次元の座標データ（Ｘ、Ｙ、Ｚ）を複数取得し、取得した点群データを三角面の集合体であるポリゴンデータに変換して立体を生成するものである。近年の３Ｄスキャナーの発展により、市販品の安価な３Ｄスキャナーにより外形状を測定して簡単にデジタルデータ化できるようになった。
The step of 3D scanning the rod-shaped object having the dent formed therein and converting the data into a data is a step of scanning the rod-shaped object obtained by molding the dent with a 3D scanner and digitizing the outer shape into three-dimensional digital data. Is a device that senses irregularities of an object and captures it as 3D data, and acquires a plurality of three-dimensional coordinate data (X, Y, Z) while irradiating the object with a laser or applying a sensor. Then, the obtained point cloud data is converted into polygon data, which is a set of triangular faces, to generate a solid. With the recent development of 3D scanners, it has become possible to measure the outer shape with a commercially available inexpensive 3D scanner and easily convert it into digital data.
得られたデータに基づいてデジタル成形機により印材を造形する工程は、前記３Ｄスキャナーにより得た３次元のデジタルデータに基づいて印材を造形する工程である。近年のデジタル成形機の発展により、市販品のデジタル成形機により立体形状の製品を簡単に製作できるようになった。これにより、窪みを型取りした印鑑型の棒状物と全く同じものを造形することができる。 The step of forming a stamping material by a digital molding machine based on the obtained data is a step of forming a stamping material based on the three-dimensional digital data obtained by the 3D scanner. The recent development of digital molding machines has made it possible to easily produce three-dimensional products using commercially available digital molding machines. This makes it possible to form exactly the same stamp-shaped rod-like material as the recessed one.
前記デジタル成形機としては、３Ｄプリンタ、ＣＮＣ切削機、レーザー加工機等があり、これらの市販品を利用して印材を造形することができる。これらの機器は、前記３次元のデジタルデータの入力により３次元の成形品を高精度に造形するものであり、窪み付きの印鑑をデータに基づいて正確に成形する。 Examples of the digital molding machine include a 3D printer, a CNC cutting machine, a laser processing machine, and the like, and a stamping material can be formed using these commercially available products. These devices form a three-dimensional molded product with high accuracy by inputting the three-dimensional digital data, and accurately form a stamp with a depression based on the data.
また、可塑性を有する材質が熱可塑性樹脂の場合における印鑑の製造方法を示す工程図は、図２に示すとおりである。
この場合は、熱可塑性樹脂が常温では硬い状態であり握って指当て位置に窪みを形成することは不可能であるので、印鑑型の棒状物を加熱して軟化させる工程を経た後に窪みを形成する工程へ移行する必要がある。更には、軟化した状態で３Ｄスキャナーにより外形状を測定すると変形により誤差を発生させるおそれがあるので、窪みを形成した棒状物を冷却して硬化させる工程を経た後にデータ化する工程へ移行する必要がある。このように、印鑑型の棒状物を加熱して軟化させる工程および窪みを形成した棒状物を冷却して硬化させる工程を加えることにより、自分特有の握り方に合った窪みが形成されている印鑑を製造できることとなる。
FIG. 2 is a process diagram showing a method for manufacturing a seal in a case where the material having plasticity is a thermoplastic resin.
In this case, since the thermoplastic resin is in a hard state at room temperature and it is impossible to form a depression at a finger contact position by grasping, a depression is formed after a step of heating and softening a seal-shaped rod-shaped material. It is necessary to shift to the step of performing. Furthermore, if the outer shape is measured by a 3D scanner in a softened state, an error may occur due to deformation. Therefore, it is necessary to shift to a process of cooling and hardening the bar-like material having the pits, and then to a process of digitizing the data. There is. In this way, by adding the step of heating and softening the seal-shaped bar and the step of cooling and hardening the bar formed with the depression, the stamp formed with the depression suitable for the unique gripping method. Can be manufactured.
前記熱可塑性樹脂は、成形体をガラス転移点または融点まで加熱すると柔らかくなり、再び冷やすと固くなる樹脂であり、例えば、ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリスチレン、アクリロニトリル・ブタジエン・スチレン、アクリル、ポリブチレンテレフタレート、ポリエチレンテレフタレート等がある。 The thermoplastic resin is a resin that becomes soft when the molded body is heated to a glass transition point or a melting point, and becomes hard when cooled again, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylonitrile butadiene styrene, acryl, and poly. Examples include butylene terephthalate and polyethylene terephthalate.
以上のようにして製造した印鑑は、図３に示されるように、印鑑１の外表面にその人の握り方に合った特有の窪み２が形成されている。即ち、この窪み２はその人が押印する場合に握る自然な状態の指の配置に合わせた位置、傾斜角度、長さ、深さを有する窪み２となっており、自分の手にフィットする世界で一つだけの印鑑となる。なお、図４は印鑑の使用状態を示す斜視図である。
この結果、指と窪み２がフィットして違和感なくしっかりと押印を行うことができ、また印鑑のデザインが一人ひとり異なるため、同じ苗字であっても自分の印鑑をすぐに見分けることができる。更には、印鑑をフィットした状態で握れば自然に正しい方向を向くため印面の上下位置を間違えることがなくなるという利点もある。
As shown in FIG. 3, the seal 1 manufactured as described above has a unique depression 2 formed on the outer surface of the seal 1 in accordance with the way of grasping by the person. That is, the depression 2 is a depression 2 having a position, an inclination angle, a length, and a depth corresponding to the arrangement of fingers in a natural state that the person grasps when imprinting, so that the world fits his / her hand. It becomes only one seal. FIG. 4 is a perspective view showing the use state of the seal.
As a result, the finger and the depression 2 are fitted to each other, so that the seal can be firmly performed without a sense of incongruity, and since the designs of the seals are different from one another, it is possible to immediately identify one's own seal even with the same last name. In addition, there is an advantage that if the seal is held in a fitted state, the seal is naturally oriented in the correct direction, so that the vertical position of the seal is not mistaken.
以上の説明からも明らかなように、本発明は可塑性を有する材質からなる印鑑型の棒状物を握って指当て位置に窪みを形成する工程と、窪みを形成した棒状物を３Ｄスキャンしてデータ化する工程と、得られたデータに基づいてデジタル成形機により印材を造形する工程からなる印鑑の製造方法であり、自分の指に合っており、かつ自分特有の握り方に合った窪みが形成されている世界で一つだけの印鑑を、簡単かつ安価に製造することができることとなる。 As is clear from the above description, the present invention provides a process in which a stamp-shaped bar made of a plastic material is gripped to form a depression at a finger contact position, and a data is obtained by 3D scanning the bar formed with the depression. This is a manufacturing method of a seal stamp, which consists of a process of converting the material and a process of forming a stamping material by a digital molding machine based on the obtained data, and forms a depression that fits your own finger and fits your own unique gripping method In this world, only one seal can be manufactured easily and inexpensively.
