PURPOSE: A supporting board is provided to prevent characters from being smeared or notes from getting dirty. CONSTITUTION: A supporting board(100) comprises a body unit(130), a supporting unit(110), a support part(150), a first hinge part(160), and a second hinge part(180). The supporting unit is formed to be supported by a writing instrument having a black lead at one side of the main body. The supporting part is combined with the other side of the main body and supports a hand of a user so that the supporting unit can be separated. The first hinge part is combined in an area which connects the main body to the supporting unit so that the main body can be rotated around the supporting unit. The second hinge part is combined in an area which connects the main body to the supporting part so that the supporting part can be rotated around the main body. |
