Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a pencil having an eraser attached to one end thereof is present heretofore but, in a case ready to use the eraser in order to correct an error in writing generated during writing using this pencil, it is necessary to perform operation for reversing the pencil to again hold the same and there is a case dropping the pencil when the pencil is reversed only by the right hand. <P>SOLUTION: This eraser holder is constituted of a cylindrical part for holding an inwardly inserted writing utensil, an eraser holding part for holding the eraser and an arm part for integrally connecting the cylindrical part and the eraser holding part. The cylindrical part 11 holds the writing utensil such as a pencil or the like inserted in the cylindrical part and the eraser 13 is fixed to the leading end 12a of the arm part 12, formed so as to continue to the cylindrical part 11, by an adhesive. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an eraser holder for attaching an eraser to a writing instrument such as a pencil.

[0002]

2. Description of the Related Art Conventionally, there is a pencil having an eraser attached at one end. If a correction occurs while writing with a pencil, this can be quickly erased using an eraser at the other end of the pencil.

[0003]

[Problems to be Solved by the Invention] However, if a user tries to use the eraser due to a correction while writing with a pencil having an eraser attached to one end, the operation of re-holding the pencil and reversing it is always necessary, and it is vacant. You need to use your left hand or the right hand that was holding a pencil. It's easier to change hands with your left hand, but if your left hand is blocked, you'll have to change your hand with your right hand alone, and sometimes your right hand alone would drop your pencil.

[0004]

In order to solve the above-mentioned problems, the invention of claim 1 proposes a cylindrical portion for holding a writing instrument inserted inside, an eraser holding portion for holding an eraser, and the cylindrical portion. And an eraser holder integrally formed with an eraser holder.
Here, in the eraser holder, it is possible to form a slit in the tubular portion in the axial direction, and it is also possible to form a taper on the inner surface of the tubular portion. Further, the eraser holding portion of the eraser holder can fix the eraser to the tip of the arm by adhesion, and the eraser holding portion forms a tubular portion at the tip of the arm to hold the eraser inside. It is also possible to do so.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of the present invention. In the figure, reference numeral 11 denotes a tubular portion that holds a writing instrument such as a pencil inserted inside. 12 is a tubular portion 11
Is an arm portion formed continuously with the tip 12a.
Is formed on a flat surface, and the eraser 13 is fixed by adhesion.

FIG. 2 is a vertical sectional view showing a second embodiment of the present invention, and FIG. 3 is a plan view thereof. In the figure, 2
Reference numeral 1 denotes a tubular portion that holds a writing instrument such as a pencil inserted inside. Reference numeral 22 is an arm portion formed continuously with the tubular portion 21, and the tip 22a thereof is formed into a cylindrical shape, and a cylindrical eraser 23 is held inside by an adhesive, press fit, caulking or the like. The tip 22a is not limited to a cylindrical shape, and may have a tubular shape such as a quadrangle, and the eraser 23 may also have a prismatic shape such as a quadrangle.

FIG. 4 is a vertical sectional view showing a third embodiment of the present invention. In the figure, reference numeral 31 denotes a cylindrical portion that holds a writing instrument such as a pencil inserted inside. Reference numeral 32 is an arm portion formed continuously with the tubular portion 31, and the tip 32a thereof is formed in a columnar shape, and the first half of the metal tube 34 is fitted on the outer side thereof and fixed by adhesion, press fitting, caulking or the like. . One end of a cylindrical eraser 33 is inserted inside the latter half of the metal tube 34 and is fixed by adhesion, press fitting, caulking or the like.

FIG. 5 is a vertical sectional view showing a fourth embodiment of the present invention. In the figure, reference numeral 41 designates a cylindrical portion for holding a writing instrument such as a pencil inserted inside. Reference numeral 42 denotes an arm portion formed continuously with the tubular portion 41, and the tip 42a thereof is formed in a cylindrical shape. A cylindrical eraser 43 is press-fitted and held inside the tip end 42a via an intermediate cylinder 44 formed by radially cutting a metal plate and bending it into a calyx. The intermediate cylinder 44 may be a plastic molded product.

FIG. 6 is a vertical sectional view showing a fifth embodiment of the present invention. In the figure, reference numeral 51 denotes a tubular portion, which holds a writing instrument such as a pencil inserted inside. Reference numeral 52 is an arm portion formed continuously with the tubular portion 51, and its tip 52a is formed in a columnar shape having a smaller diameter than the arm portion 52. The eraser 53 has an insertion hole formed at one end and having a diameter substantially the same as that of the tip 52a, and the tip 5 is formed by press fitting and / or bonding.
It is fitted and fixed to 2a.

FIG. 7 is an explanatory view showing a usage state of the second embodiment shown in FIGS. 2 and 3. The pencil 5 is inserted into the tubular portion 21 from the protruding side of the lead. In this state, the tip of the pencil 5 or the cylinder portion 21 is gripped for writing, and during writing of the pencil 5, the arm portion 22 and the eraser 2
Hold 3 up. Here, if a correction is made, the pencil 5 is rotated 180 degrees around the axis to move the arm 2
2 and eraser 23 are moved downward. Then, the eraser 23 is pressed and rubbed against the corrected portion of the paper. When the correction is completed, the pencil 5 is again rotated 180 degrees about the axis to move the arm portion 22 and the eraser 23 upward,
Resume writing.

As another embodiment, although not shown, the cylindrical portions 11, 21, 31, 41, 41 of the above-mentioned embodiment are not shown.
By forming the slit in the axial direction at 51, it is easy to insert a writing instrument such as a pencil. Similarly, by forming a taper on the inner surface of the cylindrical portion 11, 21, 31, 41, 51 of the above-described embodiment, it is possible to attach it to a writing instrument such as a mechanical pencil whose axial body cross section is not uniform.

[0012]

As described above, the eraser holder of the present invention is attached to the upper side of the tip of a writing instrument such as a pencil, so that if a correction occurs during writing, the finger holding the writing instrument can be used. 18 around the axis and move the writing instrument around the axis 18
When it is rotated 0 degrees, the eraser holder moves to the paper side,
As a result, the correction section can be erased by using the eraser of the eraser holding section without changing the writing instrument. Further, since the eraser holder of the present invention is held integrally with a writing instrument such as a pencil, loss of the eraser can be eliminated.
