Abstract

PURPOSE: To remove inconvenience of an omission of an eraser when the eraser is required by a method wherein an opening groove of such size that thickness of a pencil enters is formed in a part of the eraser, and the eraser is arranged at any position of the pencil by passing the pencil through the open groove. CONSTITUTION: An open groove 2 of suck size that thickness of a pencil enters is formed in a part of an eraser 1. Then, the pencil is passed through the open groove 2, and the eraser 1 is arranged at any position of the pencil. When the eraser 1 is used as a stopper for slipping of the pencil in that case, the eraser 1 is fitted to a tip side of the pencil, and the pencil is held from over the eraser 1. Then, since holding power is lightened by elasticity of the eraser 1, fatigue caused by writing can be reduced. Since the eraser 1 is used by inserting it into the open groove 2, it can be easily attached and detached. Further, since the pencil and the eraser 1 can be always integrally stored and used, there is no loss of the eraser 1 and labor for finding it can be removed. When the eraser 1 is used under a state wherein it is fitted to a tip of the pencil, the eraser is always conveniently together with the pencil.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an eraser.

[0002]

2. Description of the Related Art Most conventional erasers are square or round erasers, and they are used as an eraser alone.

[0003]

Since the conventional eraser is used alone as an eraser, there is an inconvenience that the pencil and the eraser are stored separately and when the eraser is needed, there is no eraser. There is also a pencil with an eraser, but there was the inconvenience that the instrument where the eraser was attached would come off after being used many times. It was difficult to replace the pencil with the eraser when the eraser was exhausted.

[0004]

[Means for Solving the Problems] An opening groove 2 is provided in a part of an eraser so that a pencil thickness can be accommodated therein. The open groove 2 is shown in FIG.
As shown in FIGS. 2 and 3, the shape is round, rhombic or square. The present invention is an eraser having the above structure.

[0005]

Operation: The pencil is passed through the open groove 2 provided in the eraser 1 as shown in FIG. 7. The eraser 1 can be moved and installed at any position of the pencil.

[0006]

EXAMPLES Examples of the present invention will be described. Since the eraser 1 is used in a state where it is inserted into the open groove 2, the position of the eraser may be attached to the end of the pencil or the tip, or may be arbitrarily attached depending on the convenience of the user. When using the eraser as a non-slip material for a pencil, attach it in the direction of the tip of the pencil and hold the pencil on the eraser. When the pencil is held on the eraser, the holding force becomes soft due to the flexibility of the rubber and fatigue is reduced. Since a pencil is generally held by the index finger and thumb, the eraser position is adjusted so that the eraser is positioned in the space created by the index finger and thumb so that it does not get in the way. Fig. 4, the eraser of the present invention opens as shown in Fig. 1. Since the eraser is used by inserting it into the groove 2, the eraser is firmly attached and fixed to the outer diameter of the pencil due to the elasticity of the rubber. To move the pencil, simply open it along the groove of the eraser. When the eraser is used as a sack so that the pencil lead is not broken, it may be installed at the tip of the pencil (FIG. 5). When used as a pencil with an eraser, it can be attached to the end of the pencil and used in FIG.

[0007]

Since the pencil and the eraser are held in close contact with an arbitrary position of the pencil by the elasticity of the opening groove 2 and the eraser itself, the eraser is not lost. The eraser is not slippery, so if you're wearing the eraser, you won't even roll your pencil off the desk. If you use the eraser like a sack, you can avoid breaking the sharpened pencil lead by dropping it. Since the eraser is used by inserting it into the opening groove 2, it can be easily attached and detached. If the pencil is exhausted, the eraser can be replaced with another pencil. Since the pencil and eraser can always be stored and used together, there is no need to lose or search for the eraser. If you use the eraser attached to the end of the pencil, the eraser is convenient because it is always with the pencil. When used only as an eraser, the eraser can be removed from the pencil and used as a conventional eraser.
