Description

テープカッターTape cutter
　本発明は、粘着テープ用のテープカッターに関する。 The present invention relates to a tape cutter for adhesive tape.
　従来のテープカッターとしては、例えば特許文献１に記載されたものがある。同文献に記載されたテープカッターは、粘着テープを巻芯に巻回してなるテープロールを回転自在に保持する保持部、テープロールから引き出された粘着テープの先端部が貼着される貼着部（仮留め部）、及び粘着テープを切断するための切断刃を備えている。貼着部は、保持部と切断刃との間に設けられている。 As a conventional tape cutter, there is one described in Patent Document 1, for example. The tape cutter described in the same document includes a holding part that rotatably holds a tape roll formed by winding an adhesive tape around a core, and a sticking part that sticks the leading end of the adhesive tape pulled out from the tape roll. (temporary fastening portion) and a cutting blade for cutting the adhesive tape. The sticking portion is provided between the holding portion and the cutting blade.
特開２００７－１７６６１２号公報JP 2007-176612 A
　上述のテープカッターにおいては、粘着テープを指で摘んで先端側に引っ張ることにより、粘着テープが繰り出される。このように粘着テープを指で摘めるようにするには、保持部と貼着部との間に指を入れるのに充分なスペースを確保する必要がある。そのため、保持部から切断刃までの距離を長くせざるを得ない。このことは、従来のテープカッターの小型化を妨げる要因となっていた。 In the tape cutter described above, the adhesive tape is fed out by pinching the adhesive tape with fingers and pulling it toward the tip side. In order to be able to pick up the adhesive tape with fingers in this way, it is necessary to secure a sufficient space between the holding portion and the sticking portion for inserting the fingers. Therefore, the distance from the holding portion to the cutting blade must be increased. This has been a factor hindering the miniaturization of conventional tape cutters.
　本発明は、上記課題に鑑みてなされたものであり、小型化に適した構造の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 view of the above problems, and an object of the present invention is to provide a tape cutter having a structure suitable for miniaturization.
　本発明によるテープカッターは、巻回された粘着テープ用のテープカッターであって、上記粘着テープの巻回部を回転可能に保持する保持部と、上記粘着テープにおける上記巻回部から引き出された部分である引出部を切断する切断刃と、上記巻回部と上記切断刃との間に位置し、上記粘着テープの上記引出部の一部が貼着される貼着部と、を備え、上記貼着部の幅は、上記粘着テープの幅よりも小さいことを特徴とする。 A tape cutter according to the present invention is a tape cutter for a wound adhesive tape, and includes a holding portion that rotatably holds the wound portion of the adhesive tape, and a holding portion that is pulled out from the wound portion of the adhesive tape a cutting blade that cuts the lead-out portion, which is a part, and an adhering portion that is positioned between the winding portion and the cutting blade and to which a part of the lead-out portion of the adhesive tape is affixed, The width of the sticking portion is smaller than the width of the adhesive tape.
　このテープカッターにおいては、貼着部の幅が粘着テープの幅よりも小さい。この場合、粘着テープの引出部の延在方向について貼着部と同一の領域に、貼着部に貼着されない部分が存在する。当該部分は、両面が露出しているため、指で摘むことが可能である。このため、上記領域においても、引出部を指で摘むことが可能となる。これにより、保持部から切断刃までの距離を短くしても、粘着テープの引出部を指で摘むことができる。 In this tape cutter, the width of the sticking part is smaller than the width of the adhesive tape. In this case, there is a portion not adhered to the adhered portion in the same region as the adhered portion in the extending direction of the lead-out portion of the adhesive tape. Since both sides of the portion are exposed, it is possible to pick it up with fingers. Therefore, it is possible to pick up the drawer portion with fingers even in the above region. Thereby, even if the distance from the holding part to the cutting blade is shortened, the pulled-out part of the adhesive tape can be picked up with fingers.

　図１及び図２は、それぞれ、本発明によるテープカッターの一実施形態を示す側面図及び平面図である。テープカッター１は、巻回された粘着テープ９０用のテープカッターであって、粘着テープ９０を繰り出して切断するのに用いられる。テープカッター１は、手に持って使用するタイプであってもよいし、卓上で使用するタイプであってもよい。粘着テープ９０は、円環状の芯に巻回されている。粘着テープ９０は、下面にのみ粘着面が設けられていてもよいし、両面（上面及び下面）に粘着面が設けられていてもよい。前者の例としては、例えばセロハンテープが挙げられる。後者の例としては、例えば両面テープが挙げられる。両面テープは、下面にのみ粘着面が露出していてもよいし、両面に粘着面が露出していてもよい。前者の両面テープにおいては、上面に剥離紙が貼着されている。 1 and 2 are side and plan views, respectively, of an embodiment of a tape cutter according to the present invention. The tape cutter 1 is a tape cutter for a wound adhesive tape 90 and is used to pay out and cut the adhesive tape 90 . The tape cutter 1 may be of a hand-held type or a desktop type. The adhesive tape 90 is wound around an annular core. The adhesive tape 90 may be provided with an adhesive surface only on the lower surface, or may be provided with an adhesive surface on both surfaces (upper surface and lower surface). Examples of the former include cellophane tape. Examples of the latter include, for example, double-sided tape. The adhesive surface of the double-sided tape may be exposed only on the lower surface, or may be exposed on both surfaces. In the former double-sided tape, a release paper is attached to the upper surface.
　テープカッター１は、保持部１０、切断刃２０、貼着部３０、及び腕部４０を備えている。保持部１０は、粘着テープ９０の巻回部９２を回転可能に保持する。巻回部９２は、粘着テープ９０における芯に巻回された部分であり、全体として円環状をしている。巻回部９２の各部分の下面は、巻回部９２の他の部分の上面、又は芯に貼着されている。保持部１０は、側板部１２、及び軸部１４を有している。側板部１２は、粘着テープ９０を側方から覆っている。側板部１２は、粘着テープ９０の両側に設けられていてもよいし、片側にのみ設けられていてもよい。また、側板部１２は、側方から粘着テープ９０の全体を覆っていてもよいし、一部のみを覆っていてもよい。すなわち、側板部１２は、側面視で、粘着テープ９０の全体に重なっていてもよいし、一部にのみ重なっていてもよい。 The tape cutter 1 includes a holding portion 10 , a cutting blade 20 , an adhering portion 30 and an arm portion 40 . The holding portion 10 rotatably holds the winding portion 92 of the adhesive tape 90 . The wound portion 92 is a portion wound around the core of the adhesive tape 90 and has an annular shape as a whole. The lower surface of each portion of the winding portion 92 is adhered to the upper surface or core of the other portion of the winding portion 92 . The holding portion 10 has a side plate portion 12 and a shaft portion 14 . The side plate portion 12 covers the adhesive tape 90 from the sides. The side plate portions 12 may be provided on both sides of the adhesive tape 90, or may be provided on only one side. Also, the side plate portion 12 may cover the entire adhesive tape 90 from the side, or may cover only a portion thereof. That is, the side plate portion 12 may overlap the entire adhesive tape 90 or may overlap only a portion of the adhesive tape 90 in a side view.
　軸部１４は、粘着テープ９０の芯の内側に挿通された状態で、粘着テープ９０を支持する。軸部１４は、側板部１２に固定されていてもよいし、側板部１２に対して回転可能に設けられていてもよい。前者の場合、粘着テープ９０は、繰り出される際に単独で回転する。後者の場合、粘着テープ９０は、繰り出される際に軸部１４と共に回転する。軸部１４が側板部１２に固定される場合、軸部１４は、側板部１２と一体に成形されることが好ましい。保持部１０の材料としては、例えば、プラスチック、金属、木材、又は紙類を用いることができる。プラスチックは、生分解性プラスチックであってもよい。紙類には、加工紙、及びセルロースナノファイバー（ＣＮＦ）も含まれる。 The shaft part 14 supports the adhesive tape 90 while being inserted inside the core of the adhesive tape 90 . The shaft portion 14 may be fixed to the side plate portion 12 or may be provided rotatably with respect to the side plate portion 12 . In the former case, the adhesive tape 90 rotates independently when it is paid out. In the latter case, the adhesive tape 90 rotates together with the shaft portion 14 when unwound. When the shaft portion 14 is fixed to the side plate portion 12 , the shaft portion 14 is preferably molded integrally with the side plate portion 12 . As a material of the holding part 10, for example, plastic, metal, wood, or paper can be used. The plastic may be a biodegradable plastic. Papers also include processed papers and cellulose nanofibers (CNF).
　切断刃２０は、粘着テープ９０の引出部９４を切断する。引出部９４は、粘着テープ９０における巻回部９２から引き出された部分である。それゆえ、引出部９４の下面は、巻回部９２の上面にも芯にも貼着されていない。切断刃２０は、巻回部９２から離間して配置されている。これにより、切断刃２０は、一定の長さの引出部９４を残して、引出部９４を切断する。引出部９４を切断する際、切断刃２０は、引出部９４の下面に当接する。切断刃２０の材料は、保持部１０の材料と同一であってもよいし、異なっていてもよい。切断刃２０は、保持部１０と一体に成形されてもよい。 The cutting blade 20 cuts the lead-out portion 94 of the adhesive tape 90 . The pull-out portion 94 is a portion of the adhesive tape 90 pulled out from the winding portion 92 . Therefore, the lower surface of the lead-out portion 94 is attached neither to the upper surface of the wound portion 92 nor to the core. The cutting blade 20 is arranged apart from the winding portion 92 . Thereby, the cutting blade 20 cuts the lead-out portion 94 leaving a certain length of the lead-out portion 94 . When cutting the lead-out portion 94 , the cutting blade 20 contacts the lower surface of the lead-out portion 94 . The material of the cutting blade 20 may be the same as or different from the material of the holding portion 10 . The cutting blade 20 may be molded integrally with the holding portion 10 .
　貼着部３０は、巻回部９２（保持部１０）と切断刃２０との間に位置する。本実施形態において貼着部３０は、切断刃２０から離間している。貼着部３０には、引出部９４の一部が貼着される。具体的には、貼着部３０の貼着面３２に、引出部９４の下面の一部が貼着される。貼着面３２は、貼着部３０の上面に等しい。貼着面３２は、平面状をしている。引出部９４の上記一部（貼着部３０に貼着される部分）は、引出部９４の先端９４ａと根元９４ｂとの間に存在する。貼着部３０の材料は、保持部１０の材料と同一であってもよいし、異なっていてもよい。 The sticking portion 30 is positioned between the winding portion 92 (holding portion 10 ) and the cutting blade 20 . In this embodiment, the sticking portion 30 is separated from the cutting blade 20 . A part of the lead-out portion 94 is attached to the attaching portion 30 . Specifically, a portion of the lower surface of the lead-out portion 94 is attached to the attachment surface 32 of the attachment portion 30 . The sticking surface 32 is equal to the upper surface of the sticking portion 30 . The sticking surface 32 is planar. The portion of the lead-out portion 94 (the portion adhered to the sticking portion 30) is present between the tip 94a and the base 94b of the lead-out portion 94. As shown in FIG. The material of the sticking portion 30 may be the same as or different from the material of the holding portion 10 .
　図３を参照しつつ、貼着部３０の寸法等について説明する。同図は、切断刃２０、貼着部３０及び引出部９４を、貼着面３２に垂直な方向から見た図である。貼着部３０の幅ｗ１は、粘着テープ９０の幅ｗ２よりも小さい。すなわち、幅ｗ１は、テープカッター１において使用することが想定される粘着テープ９０の幅ｗ２よりも小さく設計されている。幅ｗ１は、貼着面３２の幅方向（引出部９４の延在方向に垂直な方向）の寸法として定義される。幅ｗ１は、幅ｗ２の５０％以下であることが好ましく、２０％以下であることがより好ましい。当然、幅ｗ１は、切断刃２０の幅よりも小さい。幅ｗ１は、切断刃２０の幅の５０％以下であることが好ましく、２０％以下であることがより好ましい。 The dimensions and the like of the sticking portion 30 will be described with reference to FIG. This figure is a view of the cutting blade 20 , the sticking portion 30 and the lead-out portion 94 viewed from a direction perpendicular to the sticking surface 32 . Width w<b>1 of sticking portion 30 is smaller than width w<b>2 of adhesive tape 90 . That is, the width w1 is designed to be smaller than the width w2 of the adhesive tape 90 that is assumed to be used in the tape cutter 1 . The width w1 is defined as the dimension of the sticking surface 32 in the width direction (the direction perpendicular to the extending direction of the lead-out portion 94). The width w1 is preferably 50% or less of the width w2, more preferably 20% or less. Naturally, the width w1 is smaller than the width of the cutting blade 20. As shown in FIG. The width w1 is preferably 50% or less of the width of the cutting blade 20, more preferably 20% or less.
　貼着部３０の幅方向の寸法は、露出領域で、常に幅ｗ２よりも小さいことが好ましい。すなわち、露出領域内では、貼着部３０の高さ方向（図１の上下方向）の何れの位置においても、貼着部３０の幅方向の寸法が幅ｗ２よりも小さいことが好ましい。ここで、露出領域とは、側面視で、貼着部３０が露出する領域（保持部１０又は腕部４０に重ならない領域）をいう。図１において、貼着部３０のうち実線で表されている部分が、露出領域である。貼着部３０の幅方向の寸法は、露出領域で、一定であってもよいし、一定でなくてもよい。前者の場合、露出領域内では、貼着部３０の高さ方向の何れの位置においても、貼着部３０の幅方向の寸法が幅ｗ１に等しいということである。 It is preferable that the widthwise dimension of the sticking portion 30 is always smaller than the width w2 in the exposed area. That is, it is preferable that the widthwise dimension of the sticking portion 30 is smaller than the width w2 at any position in the height direction (the vertical direction in FIG. 1) of the sticking portion 30 in the exposed region. Here, the exposed region means a region where the sticking portion 30 is exposed (a region that does not overlap with the holding portion 10 or the arm portion 40) in side view. In FIG. 1, the portion of the sticking portion 30 indicated by solid lines is the exposed region. The widthwise dimension of the sticking portion 30 may or may not be constant in the exposed area. In the former case, the widthwise dimension of the sticking portion 30 is equal to the width w1 at any position in the height direction of the sticking portion 30 in the exposed region.
　貼着部３０の長さｄ１は、幅ｗ１よりも大きい。長さｄ１は、引出部９４の延在方向についての貼着面３２の寸法として定義される。長さｄ１は、例えば、５ｍｍ以上１５ｍｍ以下である。本実施形態において貼着部３０の二等分平面Ｐ１は、切断刃２０の二等分平面Ｐ２に一致している。二等分平面Ｐ１は、貼着面３２を二等分する幅方向に垂直な平面である。二等分平面Ｐ２は、切断刃２０を二等分する幅方向に垂直な平面である。 The length d1 of the sticking portion 30 is greater than the width w1. The length d1 is defined as the dimension of the sticking surface 32 in the extending direction of the lead-out portion 94. As shown in FIG. The length d1 is, for example, 5 mm or more and 15 mm or less. In this embodiment, the bisecting plane P1 of the sticking portion 30 coincides with the bisecting plane P2 of the cutting blade 20 . The bisecting plane P1 is a plane perpendicular to the width direction that bisects the sticking surface 32 . The bisecting plane P2 is a plane perpendicular to the width direction that bisects the cutting blade 20 .
　図４は、切断刃２０、貼着部３０及び粘着テープ９０を示す側面図である。同図からわかるように、側面視で、貼着部３０の貼着面３２は、基準線Ｌ１（第１基準線）の上方に位置している。基準線Ｌ１は、引出部９４の根元９４ｂと切断刃２０の先端（引出部９４の先端９４ａ）とを通る直線である。基準線Ｌ１からの貼着面３２の高さｈ１は、５ｍｍ以上であることが好ましく、１０ｍｍ以上であることがより好ましい。高さｈ１は、側面視で、貼着面３２のうち基準線Ｌ１に最も近い部分（本実施形態の場合、後述する端部３２ｂ）から基準線Ｌ１に下した垂線の長さとして定義される。また、側面視で、貼着面３２の切断刃２０側（先端９４ａ側）の端部３２ａは、基準線Ｌ２（第２基準線）の上方に位置している。基準線Ｌ２は、貼着面３２の保持部１０側（根元９４ｂ側）の端部３２ｂと切断刃２０の先端とを通る直線である。 4 is a side view showing the cutting blade 20, the sticking portion 30 and the adhesive tape 90. FIG. As can be seen from the figure, the sticking surface 32 of the sticking portion 30 is positioned above the reference line L1 (first reference line) in a side view. The reference line L1 is a straight line passing through the base 94b of the lead-out portion 94 and the tip of the cutting blade 20 (the tip 94a of the lead-out portion 94). A height h1 of the sticking surface 32 from the reference line L1 is preferably 5 mm or more, and more preferably 10 mm or more. The height h1 is defined as the length of a perpendicular line drawn from a portion of the attachment surface 32 closest to the reference line L1 (in the case of this embodiment, an end portion 32b described later) to the reference line L1 in a side view. . Further, in a side view, the end portion 32a of the adhering surface 32 on the side of the cutting blade 20 (the side of the tip 94a) is located above the reference line L2 (second reference line). The reference line L2 is a straight line passing through the end portion 32b of the sticking surface 32 on the side of the holding portion 10 (the side of the root 94b) and the tip of the cutting blade 20. As shown in FIG.
　図１に戻って、腕部４０は、保持部１０と切断刃２０とを連結している。腕部４０は、引出部９４の下面側を通って、保持部１０から切断刃２０まで延びている。腕部４０の上方には、指を入れるスペースが存在する。腕部４０の材料は、保持部１０の材料と同一であってもよいし、異なっていてもよい。前者の場合、腕部４０は、保持部１０と一体に成形されることが好ましい。貼着部３０は、腕部４０に接続されている。詳細には、貼着部３０は、腕部４０に立設されている。貼着部３０は、腕部４０に対して動かないように固定されている。貼着部３０は、腕部４０と一体に成形されてもよい。 Returning to FIG. 1, the arm part 40 connects the holding part 10 and the cutting blade 20 . The arm portion 40 extends from the holding portion 10 to the cutting blade 20 through the lower surface side of the drawer portion 94 . A space for inserting a finger exists above the arm portion 40 . The material of the arm portion 40 may be the same as or different from that of the holding portion 10 . In the former case, the arm portion 40 is preferably molded integrally with the holding portion 10 . The sticking portion 30 is connected to the arm portion 40 . Specifically, the sticking portion 30 is erected on the arm portion 40 . The sticking part 30 is fixed so as not to move with respect to the arm part 40 . The sticking portion 30 may be molded integrally with the arm portion 40 .
　図５及び図６を参照しつつ、テープカッター１の使用方法の一例を説明する。まず、図５に示すように、引出部９４を指で摘んで、引出部９４を切断刃２０及び貼着部３０から剥がした後、引出部９４が所望の長さになるまで粘着テープ９０を引き出す。次に、図６に示すように、引出部９４を切断刃２０の先端に押し当てるようにして引出部９４を切断する。切断後、引出部９４は、再び、貼着部３０に貼着された状態となる。また、引出部９４の先端９４ａは、切断刃２０に貼着された状態となる（図１参照）。このとき、引出部９４は、切断刃２０及び貼着部３０にのみ貼着されている。すなわち、テープカッター１は、テープカッター１における切断刃２０又は貼着部３０以外の部分に引出部９４が貼着されないように構成されている。 An example of how to use the tape cutter 1 will be described with reference to FIGS. First, as shown in FIG. 5, the pull-out portion 94 is pinched with fingers, and the pull-out portion 94 is peeled off from the cutting blade 20 and the adhering portion 30. Then, the adhesive tape 90 is extended until the pull-out portion 94 reaches a desired length. pull out Next, as shown in FIG. 6, the lead-out portion 94 is cut by pressing the lead-out portion 94 against the tip of the cutting blade 20 . After cutting, the lead-out portion 94 is stuck to the sticking portion 30 again. Further, the leading end 94a of the lead-out portion 94 is stuck to the cutting blade 20 (see FIG. 1). At this time, the lead-out portion 94 is stuck only to the cutting blade 20 and the sticking portion 30 . That is, the tape cutter 1 is configured so that the pull-out portion 94 is not adhered to a portion of the tape cutter 1 other than the cutting blade 20 or the adhered portion 30 .
　テープカッター１の効果を説明する。テープカッター１においては、貼着部３０の幅ｗ１が粘着テープ９０の幅ｗ２よりも小さい。この場合、図７に示すように、粘着テープ９０の引出部９４の延在方向（同図の左右方向）について貼着部３０と同一の領域Ｒ１に、貼着部３０に貼着されない部分９４ｃ（貼着面３２から食み出す部分）が存在する。同図においては、部分９４ｃに斜線が付されている。領域Ｒ１は、側面視で貼着面３２に接している領域である。部分９４ｃは、両面が露出しているため、指で摘むことが可能である。このため、領域Ｒ１においても、引出部９４を指で摘むことが可能となる。これにより、保持部１０から切断刃２０までの距離を短くしても、粘着テープ９０の引出部９４を指で摘むことができる。したがって、小型化に適した構造のテープカッター１が実現されている。 Explain the effects of Tape Cutter 1. In the tape cutter 1 , the width w<b>1 of the sticking portion 30 is smaller than the width w<b>2 of the adhesive tape 90 . In this case, as shown in FIG. 7, a portion 94c that is not adhered to the adhered portion 30 is located in the same region R1 as the adhered portion 30 with respect to the extension direction of the lead-out portion 94 of the adhesive tape 90 (horizontal direction in FIG. 7). (A portion protruding from the sticking surface 32) exists. In the figure, the portion 94c is hatched. The region R1 is a region in contact with the sticking surface 32 in side view. Since both sides of the portion 94c are exposed, it can be picked up with fingers. Therefore, it is possible to pick up the lead portion 94 with fingers even in the region R1. Thereby, even if the distance from the holding part 10 to the cutting blade 20 is shortened, the pulled-out part 94 of the adhesive tape 90 can be pinched with fingers. Therefore, the tape cutter 1 having a structure suitable for miniaturization is realized.
　このように保持部１０から切断刃２０までの距離を短くした場合、引出部９４の長さが小さくなるため、粘着テープ９０に塵埃が付着しにくくなる。また、引出部９４が貼着部３０に貼着されるため、引出部９４の先端９４ａが切断刃２０から離れたとしても、引出部９４が巻回部９２に戻ってしまう事態を起こりにくくすることができる。さらに、貼着部３０の幅ｗ１が粘着テープ９０の幅ｗ２よりも小さい場合、幅ｗ１を変えることにより、粘着テープ９０との接触面積、ひいては粘着テープ９０との間の粘着力を調整することができる。これにより、貼着部３０の材料の選択肢が増えるため、貼着部３０を他の部分（保持部１０、切断刃２０、及び／又は腕部４０）と一体に成形しやすくなる。 When the distance from the holding part 10 to the cutting blade 20 is shortened in this way, the length of the lead-out part 94 is shortened, so dust is less likely to adhere to the adhesive tape 90 . Further, since the lead-out portion 94 is attached to the sticking portion 30, even if the tip 94a of the lead-out portion 94 is separated from the cutting blade 20, the situation in which the lead-out portion 94 returns to the winding portion 92 is less likely to occur. be able to. Furthermore, when the width w1 of the adhering portion 30 is smaller than the width w2 of the adhesive tape 90, the contact area with the adhesive tape 90 and, in turn, the adhesive force with the adhesive tape 90 can be adjusted by changing the width w1. can be done. This increases options for the material of the sticking portion 30, making it easier to integrally mold the sticking portion 30 with other parts (the holding portion 10, the cutting blade 20, and/or the arm portion 40).
　幅ｗ１を小さくした方が、貼着部３０に貼着されない部分９４ｃが広くなるため、部分９４ｃを指で摘みやすくなる。かかる観点から、幅ｗ１は、幅ｗ２の５０％以下であることが好ましく、２０％以下であることがより好ましい。他方、幅ｗ１が小さすぎると、貼着部３０と粘着テープ９０との間の粘着力が不充分になりかねない。かかる観点から、幅ｗ１は、幅ｗ２の５％以上であることが好ましい。 The smaller the width w1, the wider the portion 94c that is not attached to the sticking portion 30, making it easier to pick up the portion 94c with fingers. From this point of view, the width w1 is preferably 50% or less of the width w2, more preferably 20% or less. On the other hand, if the width w1 is too small, the adhesive force between the sticking portion 30 and the adhesive tape 90 may become insufficient. From this point of view, the width w1 is preferably 5% or more of the width w2.
　貼着部３０の幅方向の寸法が露出領域で常に幅ｗ２よりも小さい場合、部分９４ｃの下方に指を入れるスペースを広く確保するのに有利である。貼着部３０の幅方向の寸法が露出領域で一定である場合、露出領域内では、部分９４ｃの下方に貼着部３０が全く入り込まないため、指を入れるスペースを広く確保するのに特に有利である。 If the widthwise dimension of the sticking portion 30 is always smaller than the width w2 in the exposed area, it is advantageous to ensure a wide space for inserting a finger under the portion 94c. When the widthwise dimension of the sticking portion 30 is constant in the exposed region, the sticking portion 30 does not enter below the portion 94c in the exposed region, which is particularly advantageous for securing a wide space for inserting a finger. is.
　貼着部３０は、切断刃２０から離間している。これにより、部分９４ｃを摘む際に指が切断刃２０に触れにくくなるため、テープカッター１の安全性を高めることができる。 The sticking part 30 is separated from the cutting blade 20. This makes it difficult for fingers to touch the cutting blade 20 when pinching the portion 94c, so that the safety of the tape cutter 1 can be enhanced.
　貼着部３０の二等分平面Ｐ１は、切断刃２０の二等分平面Ｐ２に一致している。この場合、切断刃２０で引出部９４を切断する際、引出部９４が貼着部３０によって幅方向に略均等に支持されるため、切断を円滑に行いやすくなる。 The bisecting plane P1 of the sticking portion 30 coincides with the bisecting plane P2 of the cutting blade 20 . In this case, when cutting the lead-out portion 94 with the cutting blade 20, the lead-out portion 94 is supported substantially evenly in the width direction by the adhering portion 30, so that the cutting can be smoothly performed.
　貼着部３０の長さｄ１は、貼着部３０の幅ｗ１よりも大きい。このように長さｄ１を大きくすることにより、引出部９４が貼着部３０に貼着された状態を安定的に維持しやすくなる。 The length d1 of the sticking portion 30 is greater than the width w1 of the sticking portion 30. By increasing the length d1 in this way, it becomes easier to stably maintain the state in which the lead-out portion 94 is stuck to the sticking portion 30 .
　側面視で、貼着部３０の貼着面３２は、基準線Ｌ１の上方に位置している。この場合、基準線Ｌ１の上方で引出部９４を摘むことが可能になる。このように基準線Ｌ１の上方のスペースを活かすことにより、保持部１０から切断刃２０までの距離を短くしやすくなる。また、この場合、切断刃２０で引出部９４を切断する際、貼着面３２が引出部９４の下面に強く接触するため、引出部９４を貼着面３２に貼着させやすくなる。 When viewed from the side, the sticking surface 32 of the sticking portion 30 is positioned above the reference line L1. In this case, it is possible to pinch the lead portion 94 above the reference line L1. By utilizing the space above the reference line L1 in this way, the distance from the holding part 10 to the cutting blade 20 can be easily shortened. Further, in this case, when the cutting blade 20 cuts the lead-out portion 94 , the sticking surface 32 strongly contacts the lower surface of the lead-out portion 94 .
　基準線Ｌ１からの貼着面３２の高さｈ１が大きい方が、基準線Ｌ１の上方のスペースを活かすのにも、貼着面３２を引出部９４の下面に強く接触させるのにも有利である。かかる観点から、高さｈ１は、５ｍｍ以上であることが好ましく、１０ｍｍ以上であることがより好ましい。他方、高さｈ１が大きすぎると、引出部９４の切断に支障を来しかねない。かかる観点から、高さｈ１は、３０ｍｍ以下であることが好ましい。 A larger height h1 of the adhering surface 32 from the reference line L1 is advantageous in utilizing the space above the reference line L1 and in bringing the adhering surface 32 into strong contact with the lower surface of the drawer portion 94. be. From this point of view, the height h1 is preferably 5 mm or more, more preferably 10 mm or more. On the other hand, if the height h1 is too large, cutting of the lead-out portion 94 may be hindered. From this point of view, the height h1 is preferably 30 mm or less.
　側面視で、貼着面３２の端部３２ａは、基準線Ｌ２の上方に位置している。この場合、切断刃２０で引出部９４を切断する際、貼着面３２の全体が引出部９４の下面に強く接触するため、引出部９４を貼着面３２の全体に貼着させやすくなる。 As viewed from the side, the end 32a of the sticking surface 32 is located above the reference line L2. In this case, when cutting the lead-out portion 94 with the cutting blade 20 , the entire sticking surface 32 strongly contacts the lower surface of the lead-out portion 94 .
　テープカッター１は、テープカッター１における切断刃２０又は貼着部３０以外の部分に引出部９４が貼着されないように構成されている。この場合、引出部９４のうち切断刃２０にも貼着部３０にも貼着されていない部分の全体において、粘着テープ９０の両面が露出することになる。これにより、指で摘める部分の割合が大きくなる。このことも、保持部１０から切断刃２０までの距離を短くするのに有利である。 The tape cutter 1 is configured so that the pull-out portion 94 is not attached to a portion of the tape cutter 1 other than the cutting blade 20 or the attaching portion 30 . In this case, both sides of the adhesive tape 90 are exposed in the entire portion of the pull-out portion 94 that is not attached to the cutting blade 20 or the attaching portion 30 . This increases the percentage of the portion that can be picked with the fingers. This is also advantageous for shortening the distance from the holding part 10 to the cutting blade 20 .
　テープカッター１には、腕部４０が設けられている。これにより、簡易な構成で、保持部１０と切断刃２０との間に所定の間隔が保たれたテープカッター１を実現することができる。 An arm portion 40 is provided on the tape cutter 1 . This makes it possible to realize the tape cutter 1 in which a predetermined distance is maintained between the holding portion 10 and the cutting blade 20 with a simple configuration.
　腕部４０が保持部１０と一体に成形される場合、テープカッター１の製造工程を簡略化し、それによりテープカッター１の製造コストを削減することができる。 When the arm portion 40 is formed integrally with the holding portion 10, the manufacturing process of the tape cutter 1 can be simplified, thereby reducing the manufacturing cost of the tape cutter 1.
　貼着部３０は、腕部４０に接続されている。これにより、簡易な構成で、巻回部９２と切断刃２０との間に貼着部３０が配置されたテープカッター１を実現することができる。 The sticking part 30 is connected to the arm part 40 . As a result, the tape cutter 1 in which the adhering portion 30 is arranged between the winding portion 92 and the cutting blade 20 can be realized with a simple configuration.
　貼着部３０が腕部４０と一体に成形される場合、テープカッター１の製造工程を簡略化し、それによりテープカッター１の製造コストを削減することができる。 When the sticking portion 30 is formed integrally with the arm portion 40, the manufacturing process of the tape cutter 1 can be simplified, thereby reducing the manufacturing cost of the tape cutter 1.
　テープカッター１がＣＮＦを材料として含有する場合、テープカッター１の軽量化及び高強度化を図るのに有利となる。また、ＣＮＦを用いることは、環境負荷の低減にも資する。 When the tape cutter 1 contains CNF as a material, it is advantageous for reducing the weight and increasing the strength of the tape cutter 1. Moreover, using CNF also contributes to reduction of environmental load.
　粘着テープ９０が両面に粘着面が露出した両面テープである場合、下面にのみ粘着面が露出した粘着テープに比して、引出部９４の上面に塵埃が付着しやすい。それゆえ、引出部９４の長さを小さくすることのできるテープカッター１が特に有用となる。 When the adhesive tape 90 is a double-sided tape with adhesive surfaces exposed on both sides, dust tends to adhere to the upper surface of the drawer portion 94 compared to an adhesive tape with an adhesive surface exposed only on the lower surface. Therefore, the tape cutter 1 that can reduce the length of the lead-out portion 94 is particularly useful.
　本発明は、上記実施形態に限定されるものではなく、様々な変形が可能である。上記実施形態においては、貼着部３０が切断刃２０から離間している場合を例示した。しかし、貼着部３０は、切断刃２０に隣接していてもよい。その場合、貼着部３０を切断刃２０と一体に成形しやすくなる。 The present invention is not limited to the above embodiments, and various modifications are possible. In the above-described embodiment, the case where the adhering portion 30 is separated from the cutting blade 20 is exemplified. However, the sticking portion 30 may be adjacent to the cutting blade 20 . In that case, it becomes easier to form the sticking portion 30 integrally with the cutting blade 20 .
　上記実施形態においては、貼着部３０の二等分平面Ｐ１が切断刃２０の二等分平面Ｐ２に一致する場合を例示した。しかし、二等分平面Ｐ１は、例えば図８に示すように、二等分平面Ｐ２に一致しなくてもよい。この場合、引出部９４に対して貼着部３０が幅方向に偏るため、貼着部３０に貼着されない部分９４ｃを貼着部３０の片側（図８の上側）に広く確保することができる。これにより、部分９４ｃを指で摘みやすくなる。 In the above embodiment, the bisecting plane P1 of the sticking portion 30 coincides with the bisecting plane P2 of the cutting blade 20 as an example. However, the bisecting plane P1 does not have to coincide with the bisecting plane P2, for example as shown in FIG. In this case, since the sticking portion 30 is biased in the width direction with respect to the drawer portion 94, a portion 94c that is not stuck to the sticking portion 30 can be secured widely on one side of the sticking portion 30 (upper side in FIG. 8). . This makes it easier to pick up the portion 94c with fingers.
　上記実施形態においては、貼着部３０の長さｄ１が貼着部３０の幅ｗ１よりも大きい場合を例示した。しかし、長さｄ１は、幅ｗ１に等しくてもよいし、幅ｗ１より小さくてもよい。 In the above embodiment, the case where the length d1 of the sticking portion 30 is greater than the width w1 of the sticking portion 30 is exemplified. However, length d1 may be equal to width w1 or may be less than width w1.
　上記実施形態においては、側面視で貼着部３０の貼着面３２が基準線Ｌ１の上方に位置する場合を例示した。しかし、貼着面３２は、基準線Ｌ１上に位置してもよいし、基準線Ｌ１の下方に位置してもよい。その場合、引出部９４の切断後に、引出部９４を貼着面３２に指で上から押し付けることにより、引出部９４を貼着面３２に確実に貼着させることができる。 In the above embodiment, the case where the sticking surface 32 of the sticking portion 30 is positioned above the reference line L1 in side view is exemplified. However, the sticking surface 32 may be positioned on the reference line L1 or may be positioned below the reference line L1. In this case, after the lead-out portion 94 is cut, the lead-out portion 94 can be reliably attached to the attachment surface 32 by pressing the lead-out portion 94 against the attachment surface 32 from above with a finger.
　上記実施形態においては、側面視で貼着面３２の端部３２ａが基準線Ｌ２の上方に位置する場合を例示した。しかし、端部３２ａは、基準線Ｌ２上に位置してもよいし、基準線Ｌ２の下方に位置してもよい。その場合、引出部９４の切断後に、引出部９４を貼着面３２に指で上から押し付けることにより、引出部９４を貼着面３２の全体に確実に貼着させることができる。 In the above embodiment, the case where the end 32a of the sticking surface 32 is located above the reference line L2 in side view is illustrated. However, the end portion 32a may be positioned on the reference line L2 or may be positioned below the reference line L2. In this case, after the lead-out portion 94 is cut, the lead-out portion 94 can be reliably attached to the entire attachment surface 32 by pressing the lead-out portion 94 against the sticking surface 32 from above with a finger.
　上記実施形態においてテープカッター１には、例えば図９及び図１０に示すように、張出部５０が設けられていてもよい。図１０は、図９の張出部５０を上から見た図である。張出部５０は、保持部１０から引出部９４の上方に張り出している。本例において張出部５０は、貼着部３０の上方まで延びている。すなわち、張出部５０は、平面視で、貼着部３０に重なっている。張出部５０は、平面視で、貼着部３０の全体に重なっている。また、張出部５０は、切断刃２０の上方まで延びている。すなわち、張出部５０は、平面視で、切断刃２０に重なっている。ただし、張出部５０は、切断刃２０の上方に達していなくてもよいし、貼着部３０の上方に達していなくてもよい。 In the above embodiment, the tape cutter 1 may be provided with an overhang portion 50 as shown in FIGS. 9 and 10, for example. FIG. 10 is a top view of the projecting portion 50 of FIG. The overhanging portion 50 overhangs the drawer portion 94 from the holding portion 10 . In this example, the projecting portion 50 extends above the sticking portion 30 . That is, the projecting portion 50 overlaps the sticking portion 30 in plan view. The projecting portion 50 overlaps the entire sticking portion 30 in plan view. Moreover, the projecting portion 50 extends above the cutting blade 20 . That is, the projecting portion 50 overlaps the cutting blade 20 in plan view. However, the protruding portion 50 does not have to reach above the cutting blade 20 and does not have to reach above the sticking portion 30 .
　このように張出部５０を設けることにより、引出部９４に塵埃が付着するのを抑制する効果が得られる。張出部５０が貼着部３０の上方まで延びている場合、上記効果を引出部９４の広範囲に及ぼすことができる。特に張出部５０が切断刃２０の上方まで延びている場合、上記効果を引出部９４の略全体に及ぼすことができる。 By providing the protruding portion 50 in this manner, the effect of suppressing dust from adhering to the drawer portion 94 can be obtained. When the projecting portion 50 extends above the sticking portion 30 , the above effect can be exerted over a wide range of the drawing portion 94 . In particular, when the protruding portion 50 extends above the cutting blade 20 , the above effect can be exerted on substantially the entire drawn portion 94 .
