<P>PROBLEM TO BE SOLVED: To improve a working machine body moving device moving a working machine body with respect to a base by a screw mechanism. <P>SOLUTION: A flange 240 is arranged at the front end of a male screw member 148 held by a printing machine body 20, a rod 252 is fitted to the flange 240 so as to be relatively movable in the axial direction, and an engaging plate 292 attached to a projection directed to the rear of the flange 240 of the rod 252 is moved to an engaging position for engaging with an engage member 330 fixed to the base 22 and to a non-engaging position deviating from the engage member 330 in the axial direction for non-engagement by the movement of the rod 252. In drawing out the printing machine body 20 from the base 22, an operation part 308 of an attaching/detaching handle 302 is inserted to a through-hole 250, and the rod 252 is retracted to move the engaging plate 292 to the non-engaging position and to allow the male screw member 148 to rotate. After drawing out, a worker detaches the attaching/detaching handle 302 from the flange 240 to prevent other workers from rotating the flange 240 and retracting the printing machine body 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
