果を発揮する拭消面材で構成されている。2. Description of the Related Art Conventionally, a marker board for writing with a marker is one in which a liquid opaque marker liquid is applied to the surface of a enamel plate and dried so that characters and the like can be written on. When wiping off the applied and dried handwriting, Raffle having a wiping surface in which relatively thick, hard and long fibers are planted on a relatively hard base fabric surface, or a fiber having a felt-like wiping surface is used. On the other hand, a chalk board written with chalk is one in which broken chalk powder adheres to the surface of the board so that characters can be written on it, and the board surface has a file shape with a fine surface roughness due to the destruction of the chalk. Since it is only necessary to wipe off chalk powder, raffle is used which is relatively thin, soft, and has short fibers that are planted on a relatively soft base fabric surface. That is, as described above, the marker board raf and the chalk board raf are each composed of a wiping surface material that exhibits a wiping effect most suitable for the characters to be wiped.

Since it is difficult to distinguish between them, it is troublesome to check which writing board is which one and prepare the necessary raffle, and to use it properly. It is often the case that I use a marker board and a chalk board at the same time to write sentences, mathematical formulas, figures, or tables at a debriefing session, etc. In this case as well, there are two cases for the marker board and the chalk board. Not only is it inconvenient to use, it is necessary to select and use different types of Rahul each time it is used, and it is also necessary to use the same place. Always there is an inconvenience such as that it is necessary to prepare two types of Rahul to.

It is composed of two surfaces divided by a dividing line, one surface of which is composed of a wiping surface material for a marker board and the other surface of which is composed of a wiping surface material for a chalk board. Specifically, it has a gripping member having a fitting concave portion at the center of the inner surface, a fitting portion fitted in the fitting concave portion, and a bulging portion bulging from the inner surface of the gripping member. Then, the shape-retaining member formed on one surface of the bulging portion to form the two surfaces divided by a parting line extending from the end portion to the other end portion opposite to the one end surface, and so as to cover the one surface. Cover the other surface with the wiping surface material for the marker board that has been superposed on the shape-retaining member. It is composed of a wiping surface material for a chalk board superposed on a shape-retaining member, and a wiping surface is formed by a wiping surface material for a marker board and a wiping surface material for a chalk board. Preferably, the two surfaces are formed so as to be inclined in the relative direction with the section line as a boundary. In the above, as a means for attaching the wiping surface material to the shape-retaining member, a groove portion is provided along the dividing line, and each of the wiping surface material for the marker board and the wiping surface material for the chalk board is provided in the groove portion. A case in which the ends are interveningly fixed and the other ends of the wiping surface material for the marker board and the wiping surface material for the chalk board are respectively fixed to the opposite side surfaces of the shape retaining member, and the shape retaining member. Is divided into two along the dividing line, one of the shape-retaining members is overlapped with a wiping surface material for a marker board so as to cover the surface, and the other shape-retaining member is covered with the surface thereof. In some cases, a wiping surface material for a chalk board is polymerized and the divided surfaces of the two divided shape-retaining members are joined to each other, and preferably both wiping surface materials face each other on one side of the shape-retaining member. The side surface overlaps with the other side surface and the opposite side surface exposes the end surface of the wiping surface material. . In addition, the wiping surface has a rectangular shape in a plan view, and the separating line is 2 in the lateral direction.
The dividing line, the dividing line extending in the longitudinal direction so as to divide the wiping surface in two, and the dividing line extending from one corner to the other opposite corner. There are cases. Further, as the above-mentioned wiping surface material for the marker board, one made of a knitted cloth or a woven cloth in which a large number of loop elements are erected on the base cloth surface is also used as a wiping surface material for a chalk board. What is made up of a large number of thin, soft short pieces planted on the cloth surface is used.

Then, the characters on the marker are wiped off mainly by the wiping surface material for the marker board, and the characters on the chalk are wiped out mainly by the wiping surface material for the chalk board. Also, when the two surfaces consist of surfaces that are inclined in the relative direction with the dividing line as the boundary, when wiping off the characters etc. written on the marker board with the marker, while tilting in the relative direction with the dividing line as the boundary Surface, that is, the surface composed of the wiping surface material for the marker board, is rubbed while pressing it against the writing surface.Also, when wiping off the characters written on the chalk board with chalk, the dividing line is used as a boundary. Then, the other surface made of the wiping surface material for the chalk board which is inclined in the relative direction is rubbed while pressing the other surface against the writing surface to efficiently wipe the characters on the writing surface.

露出する。The wiping surface materials 9 and 12 superposed on the surface of the shape-retaining member 4 are arranged along the section line 1 as shown in FIG.
One end of each of the wiping surface material 9 for the marker board and the wiping surface material 12 for the chalk board is intervened in the groove portion 14 provided on the surface of the to secure the adhesive board with an adhesive, and The wiping face material 9 is superposed on one surface 7 and the wiping face material 12 for a chalk board is superposed on the other surface 8 in a tension state, and the other ends thereof are opposed to each other in the lateral direction. And the side surfaces of the shape-retaining member 4 facing each other in the lateral direction and the surface of the bulging portion 6 are covered by the wiping surface materials 9 and 12 in a tense state, and in the longitudinal direction. Both end surfaces of the wiping surface members 9 and 12 are exposed on the opposite side surfaces.
