TECHNICAL FIELD OF THE INVENTION
The present invention relates to an eraser, also called raful, for erasing characters and the like written on a writing board such as a blackboard and a whiteboard.
[0002]
[Prior art]
Conventionally, in order to place the eraser when not in use, a tray for placing the eraser is provided on a blackboard or a lower side of a whiteboard. Therefore, there is a disadvantage that the cost is increased by the provision of the tray. In addition, there is a pen body which is attached with a magnet and can be adsorbed to a whiteboard, and an eraser is integrated with the pen body (for example, see Patent Document 1). .

[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to provide an eraser that does not need to provide a place for non-use on a blackboard or whiteboard, and does not need to be reduced in size, and can perform an erasing operation quickly.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, a blackboard, an eraser for a writing board such as a whiteboard of the present invention is an eraser for erasing characters and the like written on a writing board such as a blackboard and a whiteboard, and a erasing section and a holder section. And the magnet is attached to the holder portion.
[0006]
Further, the blackboard, whiteboard or other writing board eraser of the present invention has a configuration in which a magnet is attached to a side portion of a holder portion, and a tray portion on which a writing instrument such as a chalk or a marker can be placed is provided on the upper surface of the holder portion. Can be
[0007]
Further, the eraser for a writing board such as a blackboard or a whiteboard according to the present invention may be configured such that a bomb is provided on an upper surface of a holder portion and the bomb is used as a tray portion.
[0008]
Further, the eraser for a writing board such as a blackboard and a whiteboard of the present invention can be configured to be used together with a writing board such as a blackboard and a whiteboard formed of a magnetic material such as steel.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The drawings show one embodiment of the present invention, and the present invention is not limited to this embodiment. First, as shown in FIG. 1, the eraser of the present invention includes a eraser 1 and a holder 2 like a general eraser.
[0010]
The eraser 1 is formed of a material suitable for erasing chalk for a blackboard, and of a material suitable for erasing ink for a whiteboard.
[0011]
The holder unit 2 fixes the eraser unit 1, but is also used by a user to hold and operate the unit. The material of the holder portion 2 is free, and can be formed of, for example, plastic or the like.
[0012]
The magnet 3 is integrally attached to the holder 2. The magnet 3 can be attached to the outer surface of the holder 2 by bonding or the like, but can also be embedded in the holder 2 and attached.
[0013]
The magnet 3 can be attached to the side surface of the holder 2. If the magnet 3 is attached to the side surface of the holder 2 in this manner, the tray 4 can be provided on the upper surface of the holder 2 and a writing instrument 5 such as a chalk or a marker can be placed on the tray 4.
[0014]
The shape of the tray portion 4 provided on the upper surface of the holder portion 2 is arbitrary. For example, as shown in the drawing, a spoiler 6 can be provided on the upper surface portion of the holder portion 2, and the spoiler 6 can be used as the tray portion 4.
[0015]
The writing board 7 such as a blackboard or a white board can be formed of a magnetic material such as steel. By doing so, the eraser of the present invention can fix the side part of the holder part 2 to which the magnet 3 is attached by attracting it to a writing board 7 such as a blackboard or a whiteboard. The eraser of the present invention can, of course, be adsorbed and fixed not only on a writing board 7 such as a blackboard or a whiteboard, but also on furniture such as a cabinet made of a magnetic material such as steel.
[0016]
A writing implement 5 such as a chalk or a marker can be placed on the tray 4 provided on the upper surface of the holder 2.
[0017]
【The invention's effect】
The eraser according to the first aspect of the present invention can be attracted and fixed to a member made of a magnetic material by a magnet attached to the holder, so that there is no need to provide a place for the eraser such as a tray on a blackboard or whiteboard. The production cost of blackboards and whiteboards can be reduced. In addition, since the eraser is integrated with the holder, the size can be increased as compared with the conventional case where the eraser is integrated with the pen body, and the erasing operation can be performed quickly.
In the eraser according to the second aspect of the present invention, a writing instrument such as a chalk or a marker can be placed on a tray provided on the upper surface of the holder of the eraser that is adsorbed and fixed. There is no need to provide a place for placing a marker or the like.
In the eraser according to the third aspect of the present invention, by using the bomb provided on the upper surface of the holder portion as the tray portion, the writing implement placed on the tray portion can be made difficult to fall.
Further, the eraser according to the present invention described in claim 4 can be fixed to a blackboard or whiteboard by sucking the eraser, so that it can be used immediately when erasing characters or the like written on the blackboard or whiteboard.
