Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eraser dirt remover for removing dirt attached to the surface of an eraser when the eraser is used.

[0002]

2. Description of the Related Art Conventionally, when pencil writing, ink writing, pastel writing, and the like are erased with an eraser, dirt adhering to the eraser has been rubbed off on paper or a desk. In some cases, it could not be removed cleanly, and this dirt could be transferred to paper or a desk.

[0003]

[Problems to be solved by the invention]

I. On paper or desks, it may not be possible to sufficiently remove the dirt attached to the eraser. Attempting to erase again with an eraser that cannot remove this stain may further stain the paper surface. B. In order to remove the dirt attached to the eraser neatly, it was necessary to rub hard. If you try to remove it by rubbing it with force, the paper may wrinkle or tear. C. If the stain adhered to the eraser is rubbed off on a paper or a desk, the stain may be transferred to the paper or the desk and become unsightly, or the transferred and crimped stain may be difficult to remove later. D. The eraser shavings that were created by removing the stains on the eraser were scattered on paper and desks, making it hard to see, and it took time to clean it. The present invention has been made to solve the above problems.

[0004]

A flat plate 1 of an arbitrary shape is formed. A hole 2 of an arbitrary shape is provided in the upper part of the flat plate 1, and means for arranging a large number of irregularities 3 of an arbitrary shape on the bottom surface of the hole 2 is provided.

[0005]

Embodiments of the present invention will be described below with reference to the drawings.

A flat plate 1 having an arbitrary shape is formed, and a hole 2 having an arbitrary shape is provided on the flat plate 1. A large number of fine irregularities 3 having an arbitrary shape are provided on the bottom surface of the hole 2.

[0007] The present invention is placed on a flat table, and one finger of one hand is supported on the upper end of the flat plate 1 as shown in FIG. 5 while holding the other hand with an eraser. Reciprocate while rubbing against the bottom of hole 2. At this time, since a large number of fine irregularities 3 are provided side by side on the bottom surface of the hole 2, the frictional force works strongly, and the effect of scraping off the surface of the eraser along with the dirt attached to the eraser with a light force is produced. In particular, it becomes easy to remove persistent dirt that has been pressed or fixed to the surface of the eraser, or dirt that has adhered in a large amount. In addition, it is easy to remove even an eraser having deteriorated elasticity, a rounded corner, or a stain attached to an eraser having a reduced size.

[0008] Since the dirt attached to the eraser is removed on the bottom surface of the hole 2 of the present invention, the paper is wrinkled or torn, and the paper is wrinkled or torn. It can be removed by rubbing on a paper or desk, and there is no danger of the stain being transferred to the paper or desk and becoming dirty.

The shavings of the eraser formed by removing the dirt are not pushed out of the flat plate 1 even when the eraser is reciprocated because the hole 2 has a concave shape. It does not scatter on paper or desks. Further, the shavings can be moved to a trash can and discarded collectively without having to collect and clean the shavings as in the related art.

Then, when not using the eraser,
An eraser is placed on the bottom of the hole 2 and can be used as a storage location for the eraser. As a result, it is possible to prevent the eraser from losing its location due to its unknown location or falling under the desk.

The present invention can be made of an elastic material such as rubber or soft synthetic resin. As a result, the function of the anti-slip function works to enable stable use. Further, even if the elastic member is formed of a hard material or a material having no elasticity, an elastic plate can be fixed to the lower portion of the flat plate 1 to prevent slip.

Although the present invention is formed as a single unit as shown in FIG. 1, another embodiment is shown in FIG.
If the lower plate 6 having a large number of fine irregularities 3 arranged on the upper surface is fixed below the upper plate 4 provided with the hollow portion 5 as shown in FIG. Can be.
The upper plate 4 and the lower plate 6 may be formed of different materials. Sandpaper to which fine particles are adhered can be used for the lower plate 6. If the lower plate 6 is an elastic body, it acts as a non-slip. Even if the lower plate 6 is formed of a hard material or a material having no elasticity, an elastic plate may be further fixed to the lower portion of the lower plate 6 to prevent slippage.

The flat shape of the flat plate 1 can be square as shown in FIG. A shape with a slightly rounded corner is safe and preferable. With the square shape, the flat plate 1 can be easily supported by the finger, the upper end of the corner of the flat plate 1 can be supported as shown in FIG. 5, and the eraser is rubbed with the other hand on the bottom surface of the hole 2. Does not hinder operation. In addition, since it has a symmetrical shape in the up, down, left, and right directions, the usability is improved. The size of the flat plate 1 is preferably small enough to fit in the palm of the hand. This size makes it easy to hold by hand,
When used, the upper end of the flat plate 1 is easily supported by a finger, and furthermore, it is convenient for storage and carrying, and can be stored in a pencil case.
The thickness of the flat plate 1 is preferably about 3 to 5 mm. By having such a thickness, it is easy to hold by hand, and it is easy to support the upper end of the flat plate 1 with a finger at the time of use, so that it can be used stably.

The shape of the plane of the hole 2 can be circular as shown in FIG. 2, but other shapes, for example, fruits, animals, flowers, etc. are designed to make the appearance fun. It can also be expressed.

Further, in order to arrange a large number of fine irregularities 3 on the bottom surface of the hole 2, the shape and the interval can be freely determined, but it is preferable that they are adjacent to each other finely.

[0016]

According to the present invention, dirt attached to the eraser can be removed cleanly with a light force. Thus, when this eraser is used again, characters and figures can be erased neatly. As before, even if you rub on paper or a desk, it is difficult to remove the adhered dirt neatly, transfer this dirt on paper or a desk, or scatter the shavings Can also be solved.
