1. A component mounting machine that mounts components on a board, the component mounting machine comprising:
a head configured to hold the components and mount the components onto the board;
a head moving device configured to move the head;
an imaging device provided to move together with the head by the head moving device and configured to image the board; and
a controller configured to control the operation of the head, the head moving device, and the imaging device, wherein the controller is configured to execute a lower component mounting operation that controls the head and the head moving device so that lower components are mounted on the board, an upper component mounting operation that controls the head and the head moving device so that upper components are mounted on the lower components mounted on the board such that respective ones of the lower components are located below each of the upper components, and a lower component mounting inspection operation that controls the imaging device and the head moving device so as to image the board on which the lower components are mounted and performs a mounting inspection of the lower components based on the imaging of the board on which the lower components are mounted after the lower component mounting operation is performed and before the upper component mounting operation is performed, wherein
the control device executes the lower component mounting inspection operation in an inspection mode selected from multiple inspection modes including a first inspection mode in which the lower component mounting inspection of the respective ones of the lower components located below a respective one of the upper components is performed immediately before the upper component mounting operation for the respective one of the upper components, which is sequentially performed for each of the upper components and a second inspection mode in which the lower components are all inspected continuously before the upper component mounting operation of the upper components.
