Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fine adjusting mechanism for positioning capable of smoothly adjusting the vertical moving of a fine adjustable screw, since the vertical moving adjustment of the screw was substantially impossible in a fine adjustment using a microswitch because of yearly downsizing the positioning mechanism with a potentiometer. SOLUTION: The fine adjusting mechanism comprises fine adjustable screws 4, 4' attached to a feed nut 2 in a positioning mechanism with a potentiometer, upper and lower microswitches 5, 5' positioned facing the top ends of the adjustable screws 4, 4', an adjusting hole 6 formed into the feed nut 2, and an adjusting tool 8 having a lengthwise protrusion 9 at the top end; this protrusion 9 being formed in a size near the thread pitch of the fine adjustable screws 4, 4' so that the tool 8 is inserted into the adjusting hole 6 to finely adjust the fine adjustable screws 4, 4' upward and downward respectively and rotated to shift the fine adjustable screws 4, 4' to the microswitches 5, 5', relative to the nut 2, thereby finely adjusting them.
