- the position of the lower end of the nozzle 6 is detected by driving the side imaging camera 23 to image the nozzle 6 .
- positional deviation of the side imaging camera 23 in the Z direction can be corrected.
- a measurement nozzle may be used to perform the calibration process. Since the measurement nozzle is a jig whose dimensions are designed with high accuracy, it is possible to perform calibration processing with high accuracy. On the other hand, the calibration process using the measurement nozzle requires a relatively long time because it is necessary to attach and detach the measurement nozzle to the mounting head 16 . Regarding this point, in the above-described embodiment, when it is determined that there is little need to perform the calibration process (NO in S12 of FIG. 5, NO in S34 of FIG. 6), the calibration process is not performed. In this way, the technology disclosed in this specification is more useful in determining whether or not to perform calibration processing that takes a relatively long time.
