前記本体は、前記粘着テープが引き出されることが可能に、巻回された前記粘着テープを保持し、前記刃及び前記照射部を搭載する。
ユーザが目的の箇所に貼り付けられた粘着テープを剥がすとき、粘着力が低下された部分を摘みとして粘着テープを剥がすことができるので、ユーザは、スムーズに粘着テープを剥がすことができる。
前記基材は、第1の面と、前記第1の面とは反対側の第2の面とを有する。
前記粘着層は、前記第1の面側に設けられた光硬化性の粘着層である。
前記遮光層は、前記第2の面側に設けられる。
また、本発明では、基材の第2の面に遮光層が設けられている。これにより、遮光層側からの外光(例えば、自然光)が粘着層に照射されてしまい、不必要に粘着面の粘着力が低下されてしまうことを防止することができる。
前記刃は、光硬化性の粘着面を有する粘着テープを切断可能である。
前記照射部は、前記粘着テープの前記粘着面に対して光を照射する。
前記本体は、前記粘着テープが引き出されることが可能に、巻回された前記粘着テープを保持し、前記刃及び前記照射部を搭載する。
ユーザが目的の箇所に貼り付けられた粘着テープを剥がすとき、粘着力が低下された部分を摘みとして粘着テープを剥がすことができるので、ユーザは、スムーズに粘着テープを剥がすことができる。
これにより、照射部の照射と、非照射とを切り替えることができるので、照射部による消費電力を低減させることができる。
この場合、前記スイッチ機構は、前記カバーが移動することにより電気的導通を行うコンタクタを有していてもよい。
本発明では、導電性の弾性体は、カバーに弾性力を与える機能と、照射部の照射と非照射とを切り替えるスイッチ機構のコンタクタとしての機能とを兼用する。このように、弾性体が2つの機能を兼用するので、テープカッターに用いられる部材の部品点数を低減することができ、コストを削減することができる。
例えば、蛍光灯等の外光には、紫外線の波長領域の光はほとんど含まれないので、蛍光灯などの外光により、粘着面の粘着力が不必要に低下してしまうことを防止することができる。
これにより、テープの適切な位置の粘着力を低下させることができる。
これにより、照射部からの光が本体外部へ漏れてしまうことを防止することができる。
これにより、例えば、蛍光灯からの光や、自然光等の外光が本体内部に入りこみ、粘着テープの粘着面の粘着力が不必要に低下してしまうことを防止することができる。
これにより、遮光面側からの外光が粘着面に照射されてしまい、不必要に粘着面の粘着力が低下されてしまうことを防止することができる。
前記基材は、第1の面と、前記第1の面とは反対側の第2の面とを有する。
前記粘着層は、前記第1の面側に設けられた光硬化性の粘着層である。
前記遮光層は、前記第2の面側に設けられる。
<第1実施形態>
図1は、本発明の第1実施形態に係るテープカッターを模式的に示す斜視図である。図2は、テープカッターの内部構造を示す、模式的な側方スケルトン図である。なお、本明細書中において、テープカッター100や、テープカッター100が有する各部材について、図面を見やすく表示するため、実際の大きさと異なって表示する場合がある。
剥離層4が紫外線遮蔽性を有することで、例えば、蛍光灯からの光や自然光などの外光が基材3の上面側から粘着層1へ到達し、不必要に粘着層1の粘着力が低下してしまうことを防止することができる。
粘着テープは、粘着剤、接着剤、剥離剤に所定の成分を混合することで、製造することができるので、既存の設備を変更することなく製造可能である。
なお、以降の説明では、切り欠き部21が設けられた側を前方側、反対側を後方側として説明する。
これにより、蛍光灯や自然光等の外光により、粘着テープ5の粘着層1の粘着力が不必要に低下してしまうことを防止することができる。
接点61、62は、導線75を介して照射部70及び電池72に電気的に接続される。
導電部材63は、上下方向で接点61、62に対応する位置に配置される。導電部材63は、カバー50の移動に応じて、2つの接点61、62と接触し、電池72と照射部70とを電気的に導通させて、照射部70から紫外線を照射させる。
[動作説明]
次に、テープカッター100の動作について説明する。
図6~図8は、テープカッター100の動作を説明するための図である。
次に粘着テープ5が使用されるまでの間は、刃40の切断部41は、カバー50に覆われた状態とされるので、テープカッター100の安全性を向上させることができる。
ユーザは、任意の長さに粘着テープ5を切断すると、例えば、野菜や、植木の苗などの仮止めや、工事現場での仮止め用として、粘着テープ5を目的の箇所へ貼り付ける。このとき、ユーザの指に粘着テープ5が粘着することもなく、ユーザは、スムーズに粘着テープ5を目的の箇所に貼り付けることできる。
一方で、紫外線が照射される位置が、切断端から遠すぎると、粘着テープ5の剥離時、あるいは、粘着テープの切断時にユーザにより摘まれる部分とは異なる位置の粘着力が低下してしまう。
<第2実施形態>
第2実施形態では、上述の第1実施形態と、コンタクタの構成が異なっている。従って、その点を中心に説明する。なお、第2実施形態の以降では、上述の第1実施形態と同様の構成、機能を有する部材等については、同一符号を付して説明する。
接点81、82、83、84は、導線75を介して照射部70及び電池72に電気的に接続される。
バネ78、79の上端部は、カバー50の下面に固定され、バネ78、79の下端部は、凹部22の底面に固定される。
バネ78の下端部は、接点81及び82の間を通り、これらの接点81及び82に触れない程度の細い形状を有しており、かつ、カバー50に弾性力を与えることができる程度の剛性を有している。バネ79の下端部も同様に、接点83及び84の間を通り、これらの接点83及び84に触れない程度の細い形状を有しており、かつ、カバー50に弾性力を与えることができる程度の剛性を有している。バネ78、79は、アルミニウム、銅、鉄などの導電性の材料により構成されている。
上述の各実施形態の説明では、テープカッター100及び粘着テープ5について、紫外線の波長領域の光を利用した形態について説明した。しかし、これに限られず、テープカッター100及び粘着テープ5は、可視光領域の光を利用した形態であってもよい。この場合、粘着テープ5の粘着層1は、可視光硬化性の粘着層1とされ、照射部70は、可視光硬化性の粘着層1に対して可視光領域の光を照射する照射部70とされる。
