Abstract
Description
フィルム状部材と、
該フィルム状部材に形成されるアンテナ部と、
該フィルム状部材に、前記アンテナ部に接続するように実装されるICチップと、
を備えるICタグにおいて、
少なくとも前記ICタグにおける前記ICチップが実装されている面を覆っており、且つ、前記ICチップ付近の部位を覆う部分が該ICチップ付近よりも外側の部位を覆う部分よりも厚く形成された弾性体製の被覆部が設けられており、
さらに、前記被覆部が、前記ICチップ付近の部位を覆う部分と該ICチップ付近よりも外側の部位を覆う部分との境界部分の少なくとも一部が湾曲した形状となるように形成されている。
フィルム状部材と、
該フィルム状部材に形成されるアンテナ部と、
該フィルム状部材に、前記アンテナ部に接続するように実装されるICチップと、
を備えるICタグにおいて、
少なくとも、前記ICタグにおける前記ICチップが実装されている面を覆っており、且つ、前記ICチップ付近の部位を覆う部分が該ICチップ付近よりも外側の部位を覆う部分よりも厚く形成された弾性体製の被覆部が設けられており、
さらに、前記被覆部が、前記ICタグに外力が加わった際に、前記ICチップ付近の部位を覆う部分と該ICチップ付近よりも外側の部位を覆う部分との境界部分の少なくとも一部においては応力が集中する位置が連続的に変化するように形成されている。
(ICタグの概略構成)
図1は、本実施例に係るICタグの概略構成を示す図である。尚、本実施例に係るICタグは、RFIDに用いられるもので、特に、リネン製品に取付けられるICタグとして、好適に用いられる。図1(a)は本実施例に係るICタグを、ICチップが実装されている面から見た場合の平面図である。図1(b),(c)は本実施例に係るICタグの模式的断面図である。図1(b)は、図1(a)中のAA断面図であり、図1(c)は、図1(a)中のBB断面図である。
本実施例に係るICタグの優れた点について図2及び3に基づいて説明する。図2及び3は、本実施例に係るICタグにおいて、外力が加わった際に折れ曲りが発生し易い部位の例を示す図である。図2及び3においては、一点鎖線が、外力が加わった際に折れ曲りが発生し易い部位を表している。
本実施例に係るICタグの被覆部における中央付近被覆部と外側被覆部との境界部分の形状は図1に示すような形状に限られるものではない。以下、本実施例に係るICタグの変形例について図4に基づいて説明する。図4は、本変形例に係るICタグをICチップが実装されている面から見た場合の平面図である。尚、本変形例に係るICタグは、被覆部の形状のみが図1に示すICタグと異なっている。そのため、図1に示した構成と同一の構成部分については同一の符号を付して、その説明を省略する。
(ICタグの概略構成)
図5は、本実施例に係るICタグの概略構成を示す図である。尚、上述した実施例1に係るICタグと同一の構成部分については同一の符号を付して、その説明を省略する。図5(a)は本実施例に係るICタグを、ICチップが実装されている面から見た場合の平面図である。図5(b)は本実施例に係るICタグの模式的断面図であり、図5(a)中のAA断面図である。
本実施例に係る構成によれば、ICタグ100に対しICチップ130の上方から押し荷重が加わった場合、中央付近被覆部140aにおいて突出部140cが形成された部分に応力が集中する。そのため、ICチップ130及び該ICチップ130とアンテナ部120との接続部にかかる応力を低減することができる。従って、ICチップ130及び該ICチップ130とアンテナ部120との接続部の破損をより高い確率で抑制することができる。
本実施例に係るICタグにおける中央付近被覆部の突出部の構成は図5に示すような構成に限られるものではない。以下、本実施例に係るICタグの変形例について図6から8に基づいて説明する。図6から8は、各変形例に係るICタグをICチップが実装されている面から見た場合の平面図である。尚、これらに示す各変形例は、中央付近被覆部の突出部の構成のみが図5に示すICタグと異なっている。そのため、図5に示した構成と同一の構成部分については同一の符号を付して、その説明を省略する。
(ICタグの概略構成)
図9は、本実施例に係るICタグの概略構成を示す図である。尚、上述した実施例1に係るICタグと同一の構成部分については同一の符号を付して、その説明を省略する。図9(a)は本実施例に係るICタグを、ICチップが実装されている面から見た場合の平面図である。図9(b)は本実施例に係るICタグの模式的断面図であり、図9(a)中のAA断面図である。
本実施例に係る構成によれば、ICタグ100におけるICチップ130が実装されている面とは反対側の面も被覆部150によって覆われることで、ICタグ100がクリーニングに供された際に、ICタグ100本体におけるICチップ130が実装されている面とは反対側の面(フィルム状部材110におけるICチップ130が実装されている面とは反対側の面)が、クリーニングに使用される溶液に直接晒されることを抑制することができる。そのため、ICタグ100が、ICチップ130が実装されている面とは反対側の面から破損することを抑制することができる。
以下、本実施例に係るICタグの変形例について図10に基づいて説明する。図10(a)は本変形例に係るICタグを、ICチップが実装されている面から見た場合の平面図である。図10(b)は本変形例に係るICタグの模式的断面図であり、図10(a)中のAA断面図である。尚、本変形例に係るICタグは、ICチップが実装されている面とは反対側の面を覆う被覆部の構成のみが図9に示すICタグと異なっている。そのため、図9に示した構成と同一の構成部分については同一の符号を付して、その説明を省略する。
図11は、本実施例に係るICタグの概略構成を示す図である。尚、上述した実施例1に係るICタグと同一の構成部分については同一の符号を付して、その説明を省略する。図11(a)は本実施例に係るICタグの斜視図である。図11(b)は本実施例に係るICタグの模式的断面図であり、図11(a)中のAA断面図である。尚、図11においては、アンテナ部の図示を省略している。
本実施例のように、被覆部140における中央付近被覆部140aと外側被覆部140bとの境界部分Z及び中央付近被覆部140aにおける突出部140gの外周壁面Wを上記のような傾斜面とすることで、ICチップ130が実装されたフィルム状部材110に対し被覆部140を設ける際の加工が容易となる。
