Abstract
A horn-holder pivot type bonding apparatus including a horn holder for holding an ultrasonic horn, and a motor for driving the horn holder to pivot, with an imaginary pivot point of the horn holder being positionally fixed on a bonding surface. The motor is provided substantially in the center of the upper portion of the horn holder. The horn holder is formed with circular arc sections in the forward and rearward portions with respect to the imaginary pivot point; and a bonding head has, at portions corresponding to the circular arc sections of the horn holder, forward and rearward cams so that the cams are pivotable by supporting shafts. The forward and rearward cams have circular arc sections that contact the circular arc sections of the horn holder, the circular arc shape of the circular arc sections of the forward and rearward cams being centered on the supporting shafts.
