It is characterized by being located on a bias line that is biased downward in a concave shape. In this case, the bias line that is concavely biased downward with respect to the horizontal line connecting both ends in the width direction of the planar member is, for example, either a substantially U shape that is curvedly curved or a substantially V shape that is linearly biased. Also good.

また、請求項７に記載の発明は、請求項１ないし５のいずれかに記載のテープ用切断刃において、夫々の単位刃の上記エッジ部が、上記平面部材の幅方向の両端を結ぶ水平線に対して上方に凸状に偏倚する偏倚線上に位置する、ことを特徴とする。この場合、平面部材の幅方向の両端を結ぶ水平線に対して上方に凸状に偏倚する偏倚線としては、例えば曲線状に偏倚する略逆Ｕ形状や直線状に偏倚する略逆Ｖ形状のいずれであってもよい。 According to a seventh aspect of the present invention, in the tape cutting blade according to any one of the first to fifth aspects, the edge portion of each unit blade is a horizontal line connecting both ends in the width direction of the planar member. On the other hand, it is located on a deviation line that is convex upward. In this case, as the bias line that is convex upward with respect to the horizontal line that connects both ends of the planar member in the width direction, for example, either a substantially inverted U shape that is curvedly curved or a substantially inverted V shape that is linearly biased It may be.

また、請求項８に記載の発明は、請求項１ないし５のいずれかに記載のテープ用切断刃において、夫々の単位刃の上記エッジ部が、上記平面部材の幅方向の両端を結ぶ水平線に対して上下方向に凹凸状に偏倚する偏倚線上に位置する、ことを特徴とする。この場合、平面部材の幅方向の両端を結ぶ水平線に対して上下方向に凹凸状に偏倚する偏倚線としては、例えば曲線状あるいは直線状に偏倚する略波形状のいずれであってもよい。 The invention according to claim 8 is the tape cutting blade according to any one of claims 1 to 5 , wherein the edge portion of each unit blade is a horizontal line connecting both ends in the width direction of the planar member. On the other hand, it is located on a deviation line that is uneven in the vertical direction. In this case, the deviation line that is unevenly deviated in the vertical direction with respect to the horizontal line that connects both ends in the width direction of the planar member may be, for example, either a curved shape or a substantially wave shape that deviates linearly.

また、請求項９に記載の発明は、請求項１ないし８のいずれかに記載のテープ用切断刃において、内側面に接着剤が塗布された接着テープを繰り出して切断するためのテープカッターに取り付けられ、上記平面部材の他端部に該平面部材の幅方向に渡って板面から上方に突出する突出部を設け、繰り出された上記接着テープが該突出部において仮止めされた後、上記一端縁に設けられた刃先に至るようにした、ことを特徴とする。 The invention according to claim 9 is the tape cutting blade according to any of claims 1 to 8 , wherein the tape cutting blade is attached to a tape cutter for feeding and cutting an adhesive tape having an inner surface coated with an adhesive. And the other end of the planar member is provided with a projecting portion that projects upward from the plate surface across the width direction of the planar member, and the one end of the adhesive tape is temporarily fixed at the projecting portion, and then the one end It is characterized in that it reaches the cutting edge provided at the edge.

（１）請求項１〜８に記載の発明によれば、テープ切断時にテープ繰り出し方向からみて下に真っ直ぐ引くと、テープの一部が平面部材の幅方向の両端を結ぶ水平線に対して偏倚する偏倚線上に位置する上端角部に接触して切り込み線が生じ、上端角部に連なるエッジ部により切り込み線が切断されてゆき、隣の単位刃の上端角部によって更に切り込まれるという繰り返しによってテープを幅方向に一直線状に切断することができる。したがって、テープを捻るように切断する等のテクニックを必要とすることなく、容易に切断面が一直線状となるように切断することができる。 (1) According to the inventions described in claims 1 to 8 , when the tape is cut straight when viewed downward from the tape feeding direction, a part of the tape is biased with respect to a horizontal line connecting both ends in the width direction of the planar member. A tape is formed by repeatedly contacting the upper end corner located on the deflection line to form a cut line, cutting the cut line by the edge part connected to the upper end corner, and further cutting by the upper end corner of the adjacent unit blade. Can be cut in a straight line in the width direction. Therefore, it is possible to easily cut the cut surface so as to be in a straight line without requiring a technique such as cutting the tape so as to be twisted.

（２）請求項９に記載の発明によれば、上記（１）に加えて更に、接着テープ用のテープカッターに取り付けて使用されるので、テープの接着剤によって刃先にテープが固定された状態で、テープの切断を行うことができる。また、平面部材の他端部に突出する突出部でテープを仮止めした後に、刃先へと至らしめことができる。また、突出部の次に接するのが刃先のエッジ部であるので、陥没部の凸凹形状に従ってテープが切断されるのを防止することができると共に、一部のエッジ部以外にテープは接着していないので、次の切断のために平面部材から引き剥がす際に、弱い力で引き剥がすことができる。
(2) According to the invention described in claim 9 , in addition to the above (1), since the tape is further attached to a tape cutter for adhesive tape, the tape is fixed to the blade edge by the tape adhesive. The tape can be cut. Further, after the tape is temporarily fixed by the protruding portion protruding to the other end portion of the planar member, it can be brought to the cutting edge. In addition, since the edge part of the blade edge is in contact with the protrusion part, it is possible to prevent the tape from being cut according to the concave and convex shape of the depressed part, and the tape is bonded to other than the edge part. Therefore, it can be peeled off with a weak force when it is peeled off from the flat member for the next cutting.
