Description

本発明は、テープカッター、特にロール状のテープ（以下、テープ巻体ともいう）に好適で片手での操作が可能なハンドカッター等のテープカッターに関する。 The present invention relates to a tape cutter, and particularly to a tape cutter such as a hand cutter that is suitable for roll-shaped tape (hereinafter also referred to as a tape roll) and can be operated with one hand.

粘着テープ等のテープ巻体から必要長さのテープを引き出したり繰り出したりして切断するテープカッターとして、片手での把持や操作が可能なものが知られている。 2. Description of the Related Art Tape cutters that can be held and operated with one hand are known as tape cutters that pull out or feed out and cut a required length of tape from a tape roll such as an adhesive tape.

この種のテープカッターとして、例えば特許文献１には、図１０に示すように、操作入力が可能な摺動部１３０を図１０（ａ）中の矢印Ｓｃ方向に移動させると、粘着テープ１０１の切断位置１０１ａより内奥側で摺動部１３０のテープ押止部１３１がテープ引出部１１１に押し付けられ、粘着テープ１０１の粘着面がテープ押止部１３１に貼り付くことで、粘着テープ１０１の切断位置１０１ａが固定され、カッター部１２０によるテープ切断の操作が容易になるハンドカッター１００が開示されている。 As this kind of tape cutter, for example, in Patent Document 1, as shown in FIG. The tape holding part 131 of the sliding part 130 is pressed against the tape pull-out part 111 on the inner back side of the cutting position 101a, and the adhesive surface of the adhesive tape 101 sticks to the tape holding part 131, whereby the adhesive tape 101 is cut. A hand cutter 100 is disclosed in which the position 101a is fixed and the tape cutting operation by the cutter section 120 is facilitated.

このハンドカッター１００では、摺動部１３０を図１０（ｂ）中の矢印ＳＦ方向に移動させると、粘着テープ１０１の先端部分をテープ引出部１１１から引き出すことができ、テープ引出し時に切断位置１０１ａを探したりテープ巻体の外周面に貼り付いた切断位置１０１ａを剥がしたりする手間がかからずに済むという利点がある。 In this hand cutter 100, when the sliding part 130 is moved in the direction of the arrow SF in FIG. There is an advantage that there is no need to spend time searching for or peeling off the cutting position 101a stuck to the outer peripheral surface of the tape roll.

特許文献２には、図１１（ａ）－（ｃ）に示すように、テープ収容部２１０を有する本体２２０と、テープ収容部２１０から引き出したテープ２１３を本体２２０の開口部２２６から送り出す送出部２４０と、開口部２２６の近傍にカッター２５２を有するカット部２５０と、送出部２４０およびカット部２５０を作動させるカム機構２３０とを備え、カム機構２３０のカムカバー２３８に対して本体２２０を押し下げるスタンプ動作により、カム機構２３０を介して送出部２４０のラチェット歯付きのプルローラ２４１を回転させたりカット部２５０のカッター２５２を切断方向に移動させたりするものが開示されている。 Patent Document 2, as shown in FIGS. 11(a) to 11(c), includes a main body 220 having a tape accommodating section 210, and a sending section that sends out the tape 213 pulled out from the tape accommodating section 210 from an opening 226 of the main body 220. 240, a cutting part 250 having a cutter 252 near the opening 226, and a cam mechanism 230 that operates the feeding part 240 and the cutting part 250, and a stamping operation that pushes down the main body 220 against the cam cover 238 of the cam mechanism 230. discloses a system in which a pull roller 241 with ratchet teeth of a delivery section 240 is rotated via a cam mechanism 230, and a cutter 252 of a cutting section 250 is moved in the cutting direction.

この装置では、テープ２１３を一定の長さだけ送り出して、先端部分２１３ａを切断し対象物３００に貼り付けるという一連の動作を一回の押下操作のみで実行することができるという利点がある。 This device has the advantage that a series of operations such as feeding out the tape 213 a certain length, cutting the tip portion 213a, and pasting it on the object 300 can be performed with only one pressing operation.

しかしながら、前述の摺動部１３０を往復動作させる従来の前者のテープカッターにあっては、摺動部１３０の移動方向に応じてテープの切断用の保持や引出し動作を切り替える構成であったため、不慣れな使用者には操作方法が容易に理解できず、近時要求されているユニバーサルデザインの観点等から、改善の余地があった。 However, in the former type of conventional tape cutter in which the sliding part 130 moves back and forth, the holding and pulling out operations for cutting the tape are switched depending on the direction of movement of the sliding part 130, which makes it difficult for users to understand. The operation method was not easy for users to understand, and there was room for improvement from the perspective of universal design, which is required in recent years.

一方、スタンプ動作を行う従来の後者のテープカッターにあっては、操作方法は明確であるものの、カム機構２３０のカムカバー２３８に対して本体２２０を押し下げる必要から、使用時の姿勢が一つに限定されてしまい、使用者によって楽な操作姿勢を選択することができないという点で、やはり、ユニバーサルデザインの観点から改善の余地があった。 On the other hand, in the case of the conventional latter type of tape cutter that performs a stamping operation, although the operation method is clear, the main body 220 must be pushed down against the cam cover 238 of the cam mechanism 230, so the posture during use is limited to one. However, there is still room for improvement from the standpoint of universal design, since the user cannot select a comfortable operating posture.

本発明は、上述のような従来の課題を解決すべくなされたものであり、操作部位の機能および操作方向が明確で理解し易く、使用者が誰でも操作が簡単で使い勝手の良いテープカッターを提供することを目的とする。 The present invention has been made in order to solve the conventional problems as described above, and provides a tape cutter that is easy to use and easy for any user to operate, with clear and easy-to-understand functions and operating directions of operating parts.
