PURPOSE:To feed selectively many type of screws in a restricted space to suit various types of machines by chucking screws of different types in each parts feeder with chucks fitted to a rotary table and turning the table to screw delivery positions. CONSTITUTION:When screws 20a, 20d, 20g and 20h are tightened in the order of descriptions, each of said screws is stored beforehand in parts feeders 1a, 1d, 1g and 1h. And a chuck 4a is made to hold the screw 20a, a table 5 is tuned until a chuck 46 and a linear feeder 2d are aligned with each other via computer control, the chuck 4b is made to hold the screw 20d, and chucks 4c, 4d and 4f are in turn made to hold the screws 20g, 20h, 20a and 20d. Then, the table 5 is further turned, the chucks 4a, 4b and 4c are brought to screw delivery positions 7a, 7b and 7c and the screws 20a, 20d and 20c are fed. Thereafter, the table 5 is further turned and the chucks 4d, 4e and 4f are brought to screw delivery positions 7a, 7b and 7c, thereby feeding the screws 20b, 20a and 20d.
