Patent ID: 7712505

Claim:
A tape cutter device comprising: a holding portion capable of holding an adhesive tape having an adhesion surface at one side thereof and a non-adhesion surface at the other side thereof; a drawing-out portion where the adhesive tape held by the holding portion is drawn out; a cutting blade that cuts the adhesive tape drawn out from the drawing-out portion, wherein the cutting blade is disposed at the non-adhesion-surface side of the adhesive tape, and is provided so as to be rotatable in a drawing-out direction of the adhesive tape as the adhesive tape is drawn out, a biasing member that biases the cutting blade in a direction opposite to the drawing-out direction of the adhesive tape; a resin plate secured with the cutting blade, the resin plate generating static electricity; a rotating roller disposed at the holding-portion side near the cutting blade so that the non-adhesion surface of the adhesive tape is wound thereupon, a rotation of the rotating roller causes the cut end portion of the adhesive tape to be flexed into a recess form so that the adhesion surface is positioned at the inner side, thereby forming a flex portion in the adhesive tape, the flex portion is held by static electricity generated by the resin plate and the rotating roller, the rotating roller rotating as the adhesive tape is drawn out, to form a fold, including a non-adhesion portion, at a cut end portion of the adhesive tape so as to be situated between the rotating roller and the cutting blade when the adhesive tape is cut; and a stopper portion constructed with the cutting blade, the stopper portion restricts a rotation of the finger placing portion, wherein a guide member is provided at an inner-side portion, situated at the holding-portion side, of the cutting blade, the guide member contacts the non-adhesion surface of the adhesive tape drawn out from the holding portion and rotates the cutting blade in the drawing-out direction of the adhesive tape against a biasing force of the biasing member, and wherein the guide member has a curved folding positioning portion.
