A glass plate cutting device 1 with a bridge frame 4 supported at its opposite ends 5 and 6 so as to be movable in a Y direction. The bridge frame 4 has an X direction linearly moving unit 3 for moving a cutter head 2 linearly in the X direction. Ball screw nuts 7 and 8 are attached rotatably to the corresponding ends 5 and 6 of the bridge frame 4. Ball screws 9 and 10 extend in the Y direction and are screwed in the corresponding nuts 7 and 8. Y direction linearly moving units 11 synchronously rotate the corresponding nuts 7 and 8 to move the bridge frame 4 in the Y direction. A further ball screw 12 extending in the X direction is provided on the bridge frame 4. A further ball screw 12 is screwed in the further ball screw nut 13 attached to an X direction linearly moving unit 3, whereby the further ball screw 13 is rotated by the X direction linearly moving unit 3 to move the cutter head 2 linearly in the X direction.
A glass plate cutting device comprising a bridge frame supported at opposite ends so as to be movable in a Y direction, the bridge frame having an X direction linearly moving means for moving a cutter head linearly in an X direction, a pair of ball screw nuts each attached rotatably to a respective one of said ends of the bridge frame, a pair of ball screws extending in the Y direction with each ball screw being screwed in a respective one of the ball screw nuts, and Y direction linearly moving means for synchronously rotating both the nuts to move the bridge frame in the Y direction.
