Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention derives a concealable pressure-sensitive adhesive tape to be attached to a corrected portion when correcting characters, symbols, lines, etc. written on paper. It relates to a simple device that cuts to a required length.

[Conventional technology]

Conventionally, correction liquids containing a high concentration of white pigments such as titanium oxide have been widely used for the correction of characters, symbols, lines, etc. written on paper in various writing inks, printing, type printing, word processor printing, copying, etc. However, in recent years, adhesive correction tapes and transfer tapes for correction have appeared.

The former adhesive correction tape is a tape that has an adhesive layer on a highly concealing base material that is generally made of paper or a metal thin film deposited on the back surface of the paper, and does not require drying time like a correction liquid. Since the correction area can be hidden and erased by simply pasting it on the paper surface, quick correction is possible, there is no risk of soiling the hands, the surrounding area, and the like like a correction liquid, and the correction area can be peeled back to the original position. Therefore, there is an advantage that a temporary correction such as temporary erasure of an inconvenient portion at the time of copying becomes possible. In the past, as a device for pulling out such an adhesive correction tape, a device in which an edge-shaped or sawtooth-shaped cutter portion is provided in a case for accommodating the tape is conventionally used.

On the other hand, the correction transfer tape is a release base material such as a plastic film provided with a concealing pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer is transferred and transferred from the base material to the paper surface to press the corrected portion. It is designed to obscure concealment. However, although such a transfer tape has the advantage that the drying time is shorter than that of the correction liquid, it cannot be used for temporary correction such as an adhesive correction tape, and the current transfer jig can perform stable transfer. However, there is a drawback that the adhesive layer is easily broken in the middle.

[Problems to be solved by the device]

Although the adhesive correction tape has many advantages as compared with the correction liquid and the transfer tape for correction as described above, the existing derivation device used for this is very insufficient in performance. That is,
According to the conventional lead-out device, the tape pulled out from the case to the required length is cut like the cellophane tape is cut in the cutter part, so the tape end does not become sharp and the corrected part looks good. There is a problem in that it cannot be adopted for important documents, and it is difficult to accurately determine the length of the tape, so that it is difficult to accurately correct a document with narrow character spacing or complicated drawings.

In view of the above situation, the present invention provides, as a device for deriving an adhesive correction tape, a device that can cut the fed-out tape into an accurate length and sharply according to the correction location, and is very easy to handle. Is intended.

[Means for solving the problem]

In order to achieve the above-mentioned object, the first of the adhesive correction tape deriving device of the present invention is a housing provided with a tape housing portion for rotatably holding a wound body of the adhesive correction tape and a tape outlet. A feed roller that feeds the tape to the outlet side by rotating in contact with the adhesive surface of the tape fed out from the section, and a cutter that cuts the tape by meshing a pair of blades at the outlet. ,
The cutter has a pair of elastic strips, each of which has a blade at its tip, and whose base ends are joined to each other in such a manner that both blades are normally open, and a pressing force for operating both strips so that both blades close. It adopts a structure characterized by being composed of a lever.

In addition, the second of the adhesive correction tape deriving device of the present invention is
The tape accommodating portion of the case forms a grip portion in the first lead-out device, a tape lead-out port is formed at the tip of the beak-shaped portion protruding from the grip portion, and the pressing lever of the cutter is provided on the upper surface side of the beak-shaped portion. In addition to being arranged, a part of the feed roller is exposed on the lower surface side.

[Action]

The adhesive correction tape fed out from the tape winding body housed in the tape housing portion of the case is sent to the tape outlet port side by rotating the feed roller, and passes through between the blade bodies of the cutter of the outlet port to the outside. Derived. And, this derived amount can be arbitrarily adjusted by the rotation amount of the feed roller,
Accurate correction can be performed by adhering the tip of the tape in line with the correction start end of the paper surface, leading it to the correction end position, cutting it by operating the cutter, and sticking the whole. Further, since the cutting by the cutter is performed by the meshing of the pair of blades, the tape end has a sharp linear shape.

It should be noted that even a cutter of a type that cuts or pushes with a sharp single-edged blade can make the tape end sharp, but it has been proved that these cutters have poor durability and cannot be put to practical use. The cause is that, in general, the base material of this kind of tape contains a large amount of high-hardness fine particles such as titanium oxide for the purpose of enhancing the concealing property, so that the cutting edge easily wears and loses sharpness early. it is conceivable that.

On the other hand, the cutter adopted in the present invention cuts the tape located between them with a pair of blades so as to bite, so that it does not require a sharp edge and is hard to wear and The cutting property is less deteriorated and the life is long. Moreover, this cutter is
Each blade is provided at the tip of a pair of elastic strips whose base ends are joined to each other. Both blades are engaged only by pressing the pressing lever, and when the levers are released, the elastic restoring force of the above-mentioned strip causes the blades to both edges. With the body open, the cutting operation is very easy.

Further, a tape accommodating portion of the case is used as a grip portion, a tape lead-out port is formed at a tip of a beak-shaped portion projecting from the grip portion, and a pressing lever of a cutter is arranged on an upper surface side of the beak-shaped portion, and a lower surface of the same. If a part of the feed roller is exposed to the side, it is possible to easily and accurately pull out and cut the tape by operating the finger while holding the pulling device with one hand.

The adhesive correction tape applied to the derivation device of the present invention is typically a high concealing base material having an adhesive layer made of paper or a metal thin film adhered to the back surface thereof as described above. However, other base materials may be used.
