A posture of the glass plate is changed based on the squareness information of a corner portion and a side of the glass plate is ground with a wheel so that squareness is revised. Each coordinate of four corner portions of the glass plate are obtained by photographing so that the squareness of the four corner portions are obtained. The posture of the glass plate is changed based on the obtained coordinates so that a reference side of the glass plate gets toward a reference variation predetermined direction. A side adjacent to the reference side is chamfered by relatively moving the glass plate or the wheel.</p> |
