Abstract: A capillary guide device (40) includes: a guide body portion (41) capable of being in contact with a capillary (8) held in a hole (7h); and a drive portion (42) which arranges the guide body portion (41) at a position capable of being in contact with the capillary (8) by moving the guide body portion (41) along an X-axis direction. The drive portion (42) includes: a table (46) connected to the guide body portion (41); a drive shaft (47b) extending in the X-axis direction and exhibiting a frictional resistance force with the table (46); and an ultrasonic element (47a) fixed to an end of the drive shaft (47b) and supplying an ultrasonic wave to the drive shaft (47b).

Abstract: This wire clamp apparatus calibration method comprises: a step for driving a driving piezoelectric element by applying a predetermined frequency that causes a pair of arm portions to vibrate in an opening/closing direction; a step for detecting whether or not end portions of the pair of arm portions collide with each other on the basis of an output current outputted from the driving piezoelectric element when the pair of arm portions are vibrating in the opening/closing direction; a step for calculating, on the basis of the detection result, reference voltages in a state where the pair of arm portions are closed; and a step for performing calibration of a drive voltage to be applied to the driving piezoelectric element on the basis of the reference voltages. Accordingly, accuracy improvement and stabilization in an opening/closing operation of the wire clamp apparatus can be achieved.
