Problems solved by technology

Moreover, the current situation is that there is an operating force of a degree that would cause discomfort to the user when cutting due to the raw material of these tapes, and / or the tape is twisted largely to intentionally concentrate the stress acting on the tape. Situations where this particular action is difficult for the user

[0044] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0045] The tape cutter 1 according to this embodiment is suitable for use in offices and homes. In addition, the tape cutting machine 1 is used to hold a refill R formed by winding a tape T such as an adhesive tape using cellophane or other resin as a base material on a paper core R1, and pull out the adhesive tape by only the Desired length and cut products.

[0046] Such as Figure 1 to Figure 9 As shown, this tape cutting machine 1 has: a main body capable of holding a refill R; a cutting blade for cutting a tape T; and a rotating body 4 holding a refill R while being rotatably supported by the main body. The main body has: a tape cutting part 21 for cutting the tape T; a shaft support part 22 for pivotally supporting the rotating body 4; a storage part 23 for accommodating a refill R; and a blade fixing part 24 for fixing a cutting blade.

[0047] In this ...

[0070] Hereinafter, regarding the second embodiment and modifications of the present invention, refer to Figure 16 ~ Figure 21 Be explained. In the present embodiment and modifications, elements corresponding to the constituent elements of the above-mentioned embodiment are given the same symbols, and specific descriptions thereof are omitted.

[0071] Such as Figure 16 As shown, in the cutting blade according to the present embodiment, the raised dimension α at which the raised portion rises is set to be larger than 0.2 mm. The configuration other than the raised dimension α is the same as that of the cutting blade 3 according to the above-mentioned first embodiment.

[0072] According to this configuration, the tape T can be cut with a smaller operation force than the product in which the above-mentioned raised dimension is set to 0.2 mm or less. Here, it is generally considered that the thickness of the skin of a human finger is about 0.2 mm. Therefore, when the thick...

Abstract

A cutting blade (3) is provided with: rising sections (31), each having a distal end-side edge (34) disposed at the distal end-side of tape (T) that has been fed out so as to rise in a direction perpendicular to the plane direction of the tape (T); and contact sections (32) that are continuously provided from the rising sections (31) to the distal end-side of the tape (T), and are able to be in contact with the surface of the tape (T) when the edges (34) cut the tape (T).

Description

technical field [0001] The present invention relates to a cutting blade and a tape cutting machine for cutting a tape unwound from a wound state to a desired length. Background technique [0002] Conventionally, various proposals have been made regarding a cutting blade that cuts a wound tape, such as an adhesive tape or a packaging film, into a desired length while the tape is unwound. Furthermore, in recent years, various types of cutting blades having a shape of a tip portion different from a shape having a sharp angle in a front view as in the past have been disclosed. (For example, refer to Patent Document 1 and Patent Document 2) [0003] The cutting blade described in the above-mentioned patent document can cut the tape with a relatively small operating force even if the sharp angle of the front view is not provided by appropriately forming the shape of the tip of the cutting blade by a technique such as punching, and since there is no front view The sharp angle pre...
