Description

  The present invention relates to a white board eraser for erasing characters written with a releasable ink on a white board.

The conventional stationary white board eraser has a white board marker cap and a shaft body each time, even if you want to erase one of the letters written on the white board with releasable ink or make a small mistake. It was inconvenient because it was necessary to pick up and wipe off the stationary white plate eraser. Furthermore, the entrepreneur who feels troublesome to hold the stationary type white board eraser often wipes it off with the fingers of his hand, which is very uncomfortable because his fingers are dirty.
In order to solve these problems, for example, there is Japanese Utility Model Publication No. 63-176695 (hereinafter referred to as (A)) in the prior application.
In (A), one holder is provided on each of both edges of the central portion of the base, which is made of an elastic material and is lightly curved toward the tip. When using, put your finger between the two holders so that the ink wiping part faces outward, and if you make a mistake, erase it with the ink wiping part.
Further, it is known that the eraser is configured integrally with the shaft body and the cap body of the writing instrument so that the writing instrument has the function of the eraser. For example, the prior applications include Japanese Utility Model Publication No. 48-97034 (hereinafter referred to as (B)) and Japanese Utility Model Application Publication No. 48-97035 (hereinafter referred to as (C)). (B) and (c) have a function as an eraser by fitting a cover tube in which a wiping portion is implanted into a shaft body or a cap body of a writing instrument.

  However, in the whiteboard eraser, the area of the wiping portion is predetermined and cannot be adjusted to the area desired by the user. Therefore, when you want to erase a character or make a small mistake, you will use the corners of the wiping part to wipe off, but even if you use the corners, you will wipe up the part you want to keep. There were also unsuitable for small mistakes and writing mistakes. Furthermore, when the holder or the cover tube is mounted on the user's finger, the shaft main body of the writing instrument, or the cap main body of the writing instrument, the diameter of the wound body such as the user's finger or a cylindrical body is limited.

  The present invention has been made paying attention to the above-mentioned problems of the prior art, and in order to wipe out small mistakes and mistakes in writing, the wiping portion can be adjusted to the area desired by the user. An object of the present invention is to provide a white plate eraser that can be wound flexibly in accordance with the diameter of the body to be wound, such as a finger or a cylindrical body.

  In order to achieve the above-mentioned object, the present invention is characterized in that a wiping portion is covered on a shaft portion formed of a shape-variable material, and is wound around a wound body at the time of use so that the wiping can be performed. This is an eraser for white board.

  In the white plate eraser of the present invention, the area of the wiping portion can be adjusted by the number of times of winding around the wound body and the diameter of the wound body. Therefore, since the wiping portion can be adjusted to an area desired by the user, the wiping portion area can be finely adjusted in order to wipe small mistakes and writing mistakes. In addition, since it is attached to the body to be wound by winding, there is no limit on the diameter of the body to be wound, such as the user's finger or tubular body, and it can be flexibly wound according to the body to be wound, It does not fall off easily after installation. Furthermore, when the eraser for white board of the present invention is wrapped around the shaft body or cap body of a fingertip or a white board marker as a body to be wound, small writing errors and partial mistakes that occur at the time of writing are There is no need to pick up and wipe the eraser. When a substantially prismatic object, a stationery, or the like is used as the body to be wound, it is possible to create a user original white plate eraser. If the wiping portion has become dirty due to use, a new white plate eraser can be unwound from the shaft core 3 and used.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1, 2, 3, 4, 5, and 6.
Reference numeral 1 denotes a shaft portion made of a shape-variable material, which has a thin cylindrical shape. However, if it can be wound, the shaft portion 1 has a particularly triangular shape, a quadrangular prism shape, or the like. I don't care. Also, the thickness may be any thickness as long as it can be wound. The material of the shaft part 1 can be a metal such as stainless steel, copper or brass, but is not limited to this. A thermoplastic resin such as pet resin, polystyrene, polyethylene, polypropylene or polyamide, or urea resin. Any material that is a thermosetting resin such as a melamine resin, a phenol resin, or the like that can be deformed to such an extent that it can be wound is intended by the applicant.

The material of the wiping portion 2 can be used as long as it can wipe off characters written with peelable ink on a white plate with synthetic fibers such as felt, polypropylene, polyethylene, and acrylic, and natural fibers such as cloth.

  Reference numeral 3 denotes a shaft core, which is wrapped with a white plate eraser when not in use. The shape is preferably a cylindrical shape, but is not particularly limited to a triangular prism shape, a quadrangular prism shape, or the like as long as it is possible to wind a white plate eraser.

  4 is a to-be-wrapped body and winds the white board eraser at the time of use. The wound body 4 is not particularly limited as long as it can wind the fingertip, the shaft main body of the writing instrument, the cap main body of the writing instrument, stationery such as a ruler, and the white board eraser of the present invention.

Next, the operation of the first embodiment of the present invention will be described.
The white plate eraser of the present invention is unwound from the shaft core 3 and wound around the fingertip 41 in a spiral shape. At this time, the wiping part 2a arises by the wiping part 2 being wound spirally. Since the area of the wiping portion 2a can be adjusted by the number of windings and the diameter of the fingertip 41, the white plate eraser is cut with scissors or the like when the area of the wiping portion 2a is the size desired by the user. To do.
Thus, for example, a white board eraser is attached to the fingertip 41 and written on the white board. When a small entry error or partial mistake is made at the time of writing, it is not necessary to re-wipe and remove the stationary eraser each time. In order to change the position of the fingertip 41 in use, the white plate eraser may be released from the fingertip 41 and wound around another fingertip 41 in a spiral shape.
After use, the white plate eraser is unwound from the fingertip 41 and wound around the shaft core 3 or the like for storage. If the wiping portion becomes dirty due to use, a new white plate eraser may be used by unscrewing from the shaft core 3.
