To carry out a shape steel material after the processing from a conveying position smoothly and automatically.

A conveyer frame having a driving roller 4 connected to a driving source is arranged at a carrying out position, the driving roller 4 is formed of a rotary shaft 4b and an outer tube 4, a gear 4a is fixed to the end of the rotary shaft 4b, and a clutch mechanism 4d is provided between the rotary shaft 4b and the outer tube 4c, so as to transmit the rotation in one direction of the rotary shaft to the outer tube, while the outer tube is made rotatable in the conveying direction of a shape steel material, when the rotary shaft is being stopped. On the other hand, the shape steel material is supported by a driven roller rotating following the transfer of the shape steel material is arranged between driving rollers, and the shape steel material carried from a processing machine main body by the rotation of the driving rollers is carried out automatically, by the driving rollers 4 and the driven roller.
