To easily carry out processing work exceeding a moving stroke by disposing a first linear movement mechanism of a large moving quantity disposed on one end side in the transverse direction of a work and a second linear movement mechanism of a small moving quantity placed on the moving bed of this first linear movement mechanism.

In the first linear movement mechanism 8 for imparting the large moving quantity S1, a screw shaft 801 which is, for example, long in size, itself has high mechanical strength and is bold and heavy 10 weight is turned by a motor of large driving force and, therefore, electrical consumption is large and so-called inertia is inevitably generated at the time of starting and stopping of the large-weight screw shaft 801. At the time of executing the processing within the small moving quantity 32, the work movement of small electric power consumption and extremely little inertia is embodied as the light weight screw shaft 171 is operated to be tuned if the work is assumed to be moved by the second linear movement mechanism 17.
