Title:
APPARATUS FOR DETECTING CENTER POSITION OF BODY
Document Type and Number:
Japanese Patent JPH0271101
Kind Code:
A
Abstract:
PURPOSE:To easily and certainly detect the center position of a body by providing a screw rod, a holder and a stopper. CONSTITUTION:Stoppers 15, 15 moving so as to be brought into contact with both surface of a body, left and right screw rods 11 rotating in order to respectively move the stoppers 15, 15 symmetrically, a guide rod 13 fixed in parallel to the screws 11 and a pair of movable holders 12 for holding the stoppers 15, 15 are provided. The stoppers 15, 15 can move relatively in a left-and-right symmetric manner on the basis of the center point of the left and right screw rods 11 in the longitudinal direction thereof by rotating the left and right screw rods 11 screwed with each other through a pair of the holders 12. Therefore, both stoppers 15, 15 are brought into contact with two side opposed surfaces of the body so as to respectively hold the body therebetween. As a result, regardless of the length between two opposed side surfaces of the body, the center point of the left and right screw rods 11 in the longitudinal direction thereof always coincides with the center position of the body. By utilizing this action, the center position of the body can be detected.
