Abstract
Description
以下、本発明に係る種シート及び種シートの製造装置について、図面を参照しながら説明する。なお、以下に説明する実施の形態によって本発明が限定されるものではない。また、各図において同じ部分には同じ符号を付し、一部の説明を省略する。また、各図は模式的に描かれたものであって、本発明は図示された形状のみに限定されるものではない。
図1は、実施の形態1に係る種シート製造装置100の主要部の模式図である。図2は、実施の形態1に係る種シート10の断面構造の模式図である。図3は、図2の種シート10を台紙表面11a側から見た平面図である。種シート製造装置100は、植物の種子57が混合されたペースト50を台紙11の表面に印刷する装置である。つまり、種シート製造装置100は、印刷対象物である台紙11の表面に、ペースト50により形成される印刷要素56を形成し、印刷物である種シート10を得るためのものである。ペースト50は、通常の印刷においてはインクに相当し、印刷要素56は、通常の印刷においてインクで形成される文字や画像を構成する1ドットに相当する。種シート製造装置100は、例えばグラビア印刷機と同様な構成を有する。即ち、種シート製造装置100は、版シリンダ20と、圧着ローラー30と、を備える。そして、版シリンダ20の表面には凹みであるセル22が形成されている。種シート製造装置100は、台紙11を版シリンダ20の表面に押しつけることにより、セル22に充填されたペースト50を台紙表面11aに転写するものである。
以上のように、種シート製造装置100は、台紙11に種子57を含むペースト50を印刷することにより、種子57を台紙表面11a上に所定のパターンに配置することができる。図2及び図3は、種シート10の一部の構造を示している。台紙表面11aには、所定のパターンに配置された印刷要素56が載置されている。台紙表面11aに配置された複数の印刷要素56は、流動体58と種子57とから構成されている。流動体58は、ペースト50に含まれる水、糊、デンプンなどから構成されており、図2及び図3に示される種シート10が完成した状態においては、固化しており、流動しない。
実施の形態2に係る種シート製造装置200及び種シート210について説明する。種シート製造装置200は、実施の形態1に係る種シート製造装置100に対し版シリンダ20の形状を変更したものである。なお、実施の形態1と同一の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
実施の形態3に係る種シート製造装置300及び種シート310について説明する。種シート製造装置300は、実施の形態1に係る種シート製造装置100に対し版シリンダ20の形状を変更したものである。なお、実施の形態1と同一の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
実施の形態4に係る種シート410aについて説明する。種シート410aは、種シート製造装置100により製造されるものであり、実施の形態1に係る種シート10に対し印刷要素56が多層で形成されていることが変更点である。実施の形態4については、実施の形態1~3に対する変更点を中心に説明し、同一の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
