Abstract: This wire shape inspecting apparatus comprises a camera which captures an image of a wire from above, a light which illuminates the wire from above, and a control unit, wherein the control unit performs: an inspection image acquiring process of acquiring a plurality of inspection images by causing the camera to capture images of the wire a plurality of times while changing a focal distance; and a first shape detecting process of identifying, in each inspection image, a light emitting portion, which is an image part including reflected light comprising light from the light that has been reflected by the wire, and identifying an actual light emitting portion position, which is the actual position of the light emitting portion, on the basis of the position of the light emitting portion in the inspection image and the focal distance when the inspection image was acquired.

Abstract: The present invention includes: an ultrasonic horn (14) to which two ultrasonic vibrations can be input to excite a capillary (15) mounted to a front end with different frequencies in a Y-direction and an X-direction; and a control unit (50) which adjusts the respective magnitude of the two ultrasonic vibrations. The Y-direction is a direction in which the ultrasonic horn (14) extends. The control unit (50) adjusts the respective magnitude of the two ultrasonic vibrations to adjust a ratio (ΔY/ΔX) of amplitude of the capillary (15) in the Y-direction and the X-direction. Thus, degradation in the quality of the joining between wires and leads is suppressed.
