Description

[Detailed description of the invention] (Field of industrial application) The invention supports cellophane tape, double-sided tape, drafting tape, etc. in a rotatable manner so that these tapes can be cut to a desired length. Regarding tape cutters.

(Prior art) Conventionally, in this type of tape cutter, the tape is press-fitted into a reel and this reel is rotatably supported by the tape cutter body, and the distance between the center of the reel and the bottom wall of the tape cutter body is It was constant and unchangeable.

However, as mentioned above, tapes range from those with a diameter of 105 mm like regular cellophane tape.
There are various types of tape, from 120mm like double-sided tape to 130mm like drafting tape, and when cellophane tape is attached to a large tape cutter for drafting tape, the tape cannot be used. However,
Although such a large tape cutter is not originally required, it is uneconomical to use a large and expensive tape cutter. On the other hand, when a large-diameter drafting tape is attached to a small tape cutter for cellophane tape, the outer circumferential surface of the drafting tape comes into contact with the bottom wall of the tape cutter body, making the tape unable to rotate and making it impossible to use it. There were some inconveniences, such as an impossible situation.

Therefore, as a solution to such problems, Publication Utility Model Publications No. 46-9837 and Publication No. 47-98
Japanese Patent No. 39275 discloses a tape cutter in which a pair of side walls of a tape cutter body are formed with two supporting parts, upper and lower, for supporting a reel.

However, with something like this, if you make a mistake in selecting the upper and lower support parts, that is, a large diameter tape is used to some extent, and when it becomes small diameter and is supported by the lower support part via the reel, the tape will be damaged. If the tape comes into contact with the bottom wall of the tape cutter body and the tape cannot rotate smoothly, the reel on which the tape is placed must be removed from the support again and attached to a new support, making the operation cumbersome. . In particular, in a conventional example in which a plurality of bearing parts are formed above and below, the more the number of bearing parts increases, the more cases of wrong selection of the bearing parts, and the more the number of attachments and attachments to the bearing parts. This increases the number of support parts, making the operation even more troublesome.Furthermore, the height of the pair of side walls increases due to the addition of the supporting parts, resulting in an increase in the size of the tape cutter body.

(Purpose) The present invention was devised in view of the above-mentioned problems.The tape cutter body itself does not need to be enlarged, and once the reel is attached to the support, there is no need to attach it again. The purpose of the present invention is to provide a tape cutter that can be attached and used in the optimum condition for everything from large-diameter drafting tape to small-diameter cellophane tape.

(Structure) In order to achieve the above object, the tape cutter of the present invention has one end of the reel holder, which is installed upright on the left and right sides of the bottom wall of the tape cutter body, rotatably pivoted to the tape cutter body. By rotating the reel holder around the pivot joint, the pair of reel shaft support parts formed on the left and right upper parts of the reel shaft can be moved away from and approached the bottom wall of the tape cutter body. A plurality of engaging portions and a plurality of engaged portions for releasably locking the reel to the tape cutter body at a plurality of positions in the vertical direction are provided, one of which is provided at the lower part of the reel holder and the other is provided on the tape cutter body.
