次に、本発明に係るテープカッターの使用方法（作用）について説明する。
使用者は、粘着テープ巻体１から粘着テープ10を引き出し、前方倒れ姿勢の揺動カッター部材３で切断することで、固定貼着作業用（通常使用）の粘着テープ片を容易に形成できる。 Next, the usage method (action) of the tape cutter according to the present invention will be described.
The user can easily form a pressure-sensitive adhesive tape piece for fixing and sticking work (usually used) by pulling out the pressure-sensitive adhesive tape 10 from the pressure-sensitive adhesive tape roll 1 and cutting it with the swinging cutter member 3 in the forward tilted position.

そして、梱包作業等において、粘着テープ10を用いて仮止めしたい場合は、待機状態（図３及び図11参照）から、指で揺動カッター部材３を押して後方揺動させると、舌片部31によって、テープ先端領域Ｅが下方へ撓まず（垂れず）、スムーズに上方凸形に弯曲する。仮貼着部25に切断刃部39が接近し、粘着テープ10において仮貼着部25前方近傍部位と揺動カッター部材３に仮貼着した箇所の後方側部位（図４に於て切断刃部39後方近傍部位、図12に於てガイド仮着斜面61後方近傍部位10ｇ）とが相互に貼着し、上方凸形の折り返しタブ11が形成される。また、揺動カッター部材３が鉛直状姿勢に保持される。 Then, when it is desired to temporarily fix the adhesive tape 10 by using the adhesive tape 10 in the packing operation or the like, the tongue piece 31 is obtained by pushing the swing cutter member 3 backward with a finger from the standby state (see FIGS. 3 and 11). As a result, the tape tip region E does not bend downward (does not sag), and smoothly bends into an upward convex shape. The cutting blade 39 approaches the temporary adhering portion 25, and the portion near the front of the temporary adhering portion 25 in the adhesive tape 10 and the rear portion of the portion temporarily attached to the swing cutter member 3 (the cutting blade in FIG. 4). A portion near the rear of the portion 39, the portion near the rear portion 10g) of the guide temporary attachment slope 61 in FIG. Further, the swing cutter member 3 is held in a vertical posture.

また、仮貼着部25及び鉛直状姿勢の揺動カッター部材３の上方位置に、基枠２の上壁や他部材を配設していない（壁部や部材を省略している）ため、折り返しタブ11を指で摘んで上方へ持ち上げて引き出せることができ、粘着テープ10の粘着面10ｅが指の皮脂等で汚れるのを防止できる。 In addition, since the upper wall of the base frame 2 and other members are not disposed above the temporary sticking portion 25 and the swing cutter member 3 in the vertical posture (the wall portion and members are omitted), The folded tab 11 can be picked up by a finger and lifted upward to be pulled out, and the adhesive surface 10e of the adhesive tape 10 can be prevented from being soiled by the sebum of the finger.

粘着テープ10が仮貼着部25及び揺動カッター部材３から離間し、揺動カッター部材３が自重によって（自動）で、前方倒れ姿勢となる。
粘着テープ10を引き出して、折り返しタブ11より後方部位を、前方倒れ姿勢となった揺動カッター部材３で、切断することで、長手方向一端部に折り返しタブ11を有する仮止め用粘着テープ片が形成される。 The adhesive tape 10 is separated from the temporary sticking portion 25 and the swinging cutter member 3, and the swinging cutter member 3 is in a forward tilted posture by its own weight (automatic).
By pulling out the adhesive tape 10 and cutting the rear part of the folding tab 11 with the swinging cutter member 3 in the forward tilted position, the temporarily fixing adhesive tape piece having the folding tab 11 at one end in the longitudinal direction is obtained. It is formed.

特に、図11及び図12で説明したガイド仮着斜面61を設けている場合は、揺動カッター部材３を後方へ揺動させると、粘着テープ10においてガイド仮着斜面61の後方近傍部位10ｇを、図11に二点鎖線で示すように、ガイド仮着斜面61の傾斜に沿って起立させる。仮貼着部25とガイド仮着斜面61（切断刃部39）の間を確実に上方凸形に弯曲変形させる。つまり、粘着テープ10においてガイド仮着斜面61の後方近傍部位10ｇを確実に後方上傾状とでき、テープ先端領域Ｅをより確実に上方凸形に変形させて、折り返しタブ11を形成する。 In particular, in the case where the temporary guide slope 61 described with reference to FIGS. 11 and 12 is provided, when the swing cutter member 3 is swung backward, a portion 10g near the rear of the temporary guide slope 61 on the adhesive tape 10 is formed. As shown by a two-dot chain line in FIG. 11, the guide temporary attachment slope 61 is raised along the slope. The portion between the temporary sticking portion 25 and the guide temporary attaching slope 61 (cutting blade portion 39) is surely bent into an upward convex shape. That is, in the adhesive tape 10, the rear vicinity portion 10g of the guide temporary attachment slope 61 can be surely inclined upward, and the tape leading end region E is more reliably deformed into an upward convex shape to form the folded tab 11.
