A ball 27h is formed, and a ball 27h is inserted into the tool block 17H, which is bored into the tool block 17H, and a ball 27h is involved in the trap. The member 27C is elastically urged upward by the vertically moving port 1j by the spring 27e, and the clutch member 27C and the tool block 17a are pulled out by the wedge action of the plurality of balls 2711 or the taper r11127g. 1
Since the tool block 17a and the first clutch i
The l+ material 27C and the ball screw 27b are in a state where they are tightly connected as one body. In addition, as will be described later, when the clutch (441a) located above descends and engages with the clutch pawl 27f, the clutch member 27C is pushed down to release the locked state of the adjacent taper 27g and the ball 27 amount 10. The ball screw 27b becomes rotatable. That is, the slider 17b is in the north direction only when fixing in the Y-axis direction.

The Y-axis direction correction movement mechanism 103 has the following structure and engages with the clutch pawl 27C to rotate the ball screw 27b. The gear 15C provided at the base end of the servo motor shaft 140 meshes with the gear 15a and the gear 45 for transmission. At the engagement position 1h above (FIG. 2) opposite to the clutch pawl 27f of the single clutch member 27C, there is a transmission shaft 41 carrying a clutch u't 41a, or

When the transmission shaft 41 is lowered, the transmission shaft 41 is also lowered, and the gear 42 meshes with the gear 45 at the lowest position. The meshing position of the gear 45 is regulated by the servo motor 101.
Since the meshing position of gear 2 is regulated at position 1c by the engagement member Isosu 47, etc., the tooth surfaces of gear 42 and gear 45 will not be in the same phase (the meshing will be ensured at a predetermined position 11-). By lowering the transmission gear 11141, the clutch groove 41a engages with the clutch pawl 27f provided on the tool block 178 in the normal position 1n, and the transmission gear 11141 is moved downward.
l141 and the ball screw 27b are in a connected state.

At this time, the crack member 27C is pushed slightly downward and moves downward against the spring 27e as described above, so that the locked state of the ball 27h and the tapered sail #27g is released. Therefore, the rotation of the servo motor 4+1114 is transmitted to the gears 15c, 15a, 45.42, rotates the ball screw 27b via the clutch Ij't 41a + clutch pawl 27f, and rotates the slider 17b
