PURPOSE:To remove the gas generating at laser cutting time on the upper and down of a cutting sheet and to reduce the environmental pollution by providing to the laser cutting head as well the suction box for flue gas deodorizing provided at the lower part of the cutting table. CONSTITUTION:A suction box 3c is set up at the lower part of a cutting table 2a and the suction box 3c' is provided also on a laser cutting head 2c as well. The suction box 3c' is located therefore at the upper part of the cutting part of a cutting sheet material 1 together with the laser cutting head 2c and linked to a flue gas deodorizer 3a by a duct hose 3b.
