Abstract
An apparatus and method for supplying a printed circuit board to a printed circuit board drilling machine and for returning the printed circuit board after the drilling. A stocker stores a plurality of printed circuit boards in a tilted state, and a plurality of conveyor rollers provides a conveying path for the printed circuit boards. A conveyor device which includes conveyor rollers provides a conveying path connected to the first mentioned conveying path. The arrival of the printed circuit board is detected at a predetermined position, and the printed circuit board is then decelerated by braking in response to a signal from the detection. A device is provided on the printed circuit board drilling machine for delivering the printed circuit board to the printed circuit board drilling machine. A base plate can be provided with a pair of locating pins for being anchored to the drilling machine table and has the printed circuit board mounted thereon so that the drilling machine can handle one pattern and number of location pins regardless of the number and pattern of fixing pins on the printed circuit board.
