, 34D, respectively.

Then, each of the insertion guides 9A, 9B, 9C, and 9D moves onto the X table 2 and inserts the irregularly shaped electronic component into the printed circuit board PB.

In addition, in the operation description of the above embodiment, four insertion guides 9
Although the case has been described in which four types of odd-shaped electronic parts corresponding to A, 9B, 9C, and 9D are specified at the same time, one to three types of the four types of odd-shaped electronic parts can also be specified.
