PURPOSE:To smoothly feed a succeeding screw or the like to a predetermined position by providing a means detecting that a screw or the like is taken out from the predetermined position and a means applying vibration to a chute. CONSTITUTION:When a power switch S1 is turned on, an optical sensor 78 is operated to detect the presence of a screw 70 on a chute 30, a transistor is turned on, and a motor driving a dipper 10 is started. Next, the bit 61 of a magnet driver 60 is lowered along the slant face of a bit guide 62 to adsorb the head section of the screw 70. When the screw 70 is extracted, a hooking member 52 is quickly returned to the position of a solid line by the energizing force of a wire spring, and the unnecessary outflow of the succeeding screw is prevented. In this case, a stopper section 54 provided on the holding member 52 hits the side section of the chute 30 to give a shock to the chute 30, thus the flow of the screw on the chute 30 is made smooth.
