Date Nov. 13, 1980.A printed circuit board (OS) with a circuit for use in a television receiver is carried to a location of a conveyor (OD) for testing process. A printed circuit board takeout device (OB), automatic parts testing device (OF), first sorting device (OG), first automatic parts measuring/adjustment device (OI), second sorting device (OJ), second automatic parts measuring/adjustment device (OK), third sorting device (OL) etc. are sequentially arranged on a path of conveyance of the printed circuit board on the conveyor (OD). The automatic parts testing device (OF) is adapted to test whether or not a component part of a desired value exists in a desired location of the printed circuit board (OS). The first sorting device (OG) is adapted to transfer an unfit printed circuit board to a conveyor (OH) for unfit printed circuit board. The first automatic parts measuring/adjustment device (OI) is adapted to primarily measure the output of the receiving system of a television circuit, while adjusting a to-be-adjusted component part through a driver device so that it has a proper circuit characteristic. The third sorting device is adapted to eventually transfer the printed circuit board to a guide device for fit printed circuit board if it is fit and to the conveyor (OH) if it is unfit.
