Abstract
A movement detector of the feeder of wire solder directly touches the wire solder, and the movement detector includes (a) a rotating body which revolves when the wire solder moves along a feeding direction and (b) a rotation detector which produces a rotation detecting signal by detecting a rotation of the rotating body. An abnormal halt detector of the feeder of the wire solder compares a rotation detecting signal from a rotation detector with a rotation instructing signal sent to a motor which feeds the wire solder, and calculates the comparison result, thereby judges an abnormal halt of the wire solder. When the abnormal halt is detected, a feeding roller for the wire solder is stopped, whereby the wire solder is prevented from being bent and deformed.
