A groove processing apparatus which processes a groove having a triangle shaped cross section on a side surface of a plate comprises: a cutting member which cuts a side surface of a plate; a first driving unit which moves the cutting member to a first position or a second position; and a second driving unit which moves the cutting member in a groove cutting direction. Here, the first position corresponds to any one of two sides having the same vertex in the triangle shape, the second position corresponds to the other one of said two sides, and the vertex is located within the plate. |
