Abstract
Abstract A tape applicator for rotatably mounting a roll of adhesive tape to adhere the tape to an article and cut off the desired length of adhered tape comprising a roller belt for mounting the tape roll on an annular portion with the belt interposed therebetween, a finger inserting apertured portion defined by the annular portion and providing a finger engaging portion, and a safety stopper and a cutter attached to the applicator main body. The cutter is slanted toward one end of the applicator from the front side to the rear side thereof. The applicator is safe to use without causing any injuries to the finger, and well-balanced and easy to use even if large-sized. The tape is applicable under suitable tension and therefore will not be creased or warp the article.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
255 words
An adhesive tape applicator comprising: a main body having a finger inserting aperture formed in its center, a swing member housed in the main body and pivotably supported at one end of the main body, the member including a guide roller and a tape press roller at one end and an annular portion in its center for rotatably mounting a roll of adhesive tape, the member further having substantially the same aperture as the above and a finger engaging portion provided in the aperture, a rotatable member provided in the main body and rotatably supported at the other end of the main body, the member including a disc rotatable by the swing member in a direction opposite to the direction of turn of the swing member when the swing member is turned toward the rotatable member and a peripheral wall projecting from the disc toward the front, a spring mounted on the main body to bias the swing member away from the rotatable member, a revolving split ring in the form of a partially cut ring interposed between the annular portion and the tape roll, a cutter attached to a slanting end of the peripheral wall of the rotatable member slanting toward the other end of the main body from the front toward the rear, and a cover detachably fittable to the main body and having substantially the same aperture as the above, whereby the pressure of fingers inserted in said aperture against said fingers engaging portion is substantially sufficient to cut said adhesive tape.
Claim 2
Dependent Claim
255 words
An adhesive tape applicator comprising: a main body having a finger inserting aperture formed in its center, a swing member housed in the main body and pivotably supported at one end of the main body, the member including a guide roller and a tape press roller at one end and an annular portion in its center for rotatably mounting a roll of adhesive tape, the member further having substantially the same aperture as the above and a finger engaging portion provided in the aperture, a rotatable member provided in the main body and rotatably supported at the other end of the main body, the member including a disc rotatable by the swing member in a direction opposite to the direction of turn of the swing member when the swing member is turned toward the rotatable member and a peripheral wall projecting from the disc toward the front, a spring mounted on the main body to bias the swing member away from the rotatable member, a revolving split ring in the form of a partially cut ring interposed between the annular portion and the tape roll, a cutter attached to a slanting end of the peripheral wall of the rotatable member slanting toward the other end of the main body from the front toward the rear, and a cover detachably fittable to the main body and having substantially the same aperture as the above, whereby the pressure of fingers inserted in said aperture against said fingers engaging portion is substantially sufficient to cut said adhesive tape.
Claim 3
Dependent Claim
23 words
The adhesive tape applicator of claim 1, wherein the rotatable member has a protecting projection at the front side of the slanting end.
Claim 4
Dependent Claim
