Summary:PURPOSE:To enable shaped cylindrical plastic magnets to be automatically adjusted in their inner and outer diameters in mass, by providing an outer diameter adjusting ring gage having an inner diameter slightly larger than a predetermined outer diameter of the cylindrical plastic magnets and an inner diameter adjusting pin gage having an outer diameter slightly smaller than a predetermined inner diameter of the magnets and a length such that the pin gage defines a straight line with the picker when it is close to or in contact with the tip of the picker, the pin gage being associated with a pressing/drawing means. CONSTITUTION:A ring gage 18 for adjusting outer diameter of works is provided with an inner diameter slightly larger than a predetermined outer diameter of a cylindrical plastic magnet and is positioned in front of the position that a picker 10 takes when it is raised. Such ring gage 18 is fixed on the right hand of a work supply section by means of a support column. Thus, an external diameter of each work can be adjusted by passing the work through a through hole 18a of the ring gage 18. On the other hand, a pin gage 20 for adjusting inner diameter of works is provided with an outer diameter slightly smaller than the predetermined inner diameter of the cylindrical plastic magnet and is positioned on the opposite side to the picker 10. Length of such pin gage 20 is determined such that the pin gage 20 is passed through the through hole 18a of the ring gage and projected toward the picker 10 and that the distal end of the pin gage is close to or in contact with the tip end of the picker 10 on the same straight line. The pin gage is associated with a pressing/drawing means 21 such as an air cylinder or the like.
