1. A component mounting machine that holds and mounts a component on a board, the machine comprising:
a head having a suction nozzle configured to hold the component;
a camera configured to image the component when the component is held in the suction nozzle; and
a control device including a processor configured to:
control the head to pick up the component with the suction nozzle,
obtain an image of the component held in the suction nozzle using the camera,
perform a pre-mounting inspection for inspecting a state of the component held in the suction nozzle based on the image of the component,
when a determination of abnormality is made in the pre-mounting inspection,
control the head to discard the component held in the suction nozzle in a discard box, and
set a flag indicating that a post-mounting inspection is required when abnormality is determined,
when a determination of normality is made in the pre-mounting inspection,
determine whether there is a suspicion of abnormality based on at least one of a time taken to perform the pre-mounting inspection and a change in an amount of positional deviation of the component held in the suction nozzle compared to a positional deviation of a previously held component,
set the flag indicating that the post-mounting inspection is required when there is a suspicion of abnormality, and
control the head so that the component held in the suction nozzle is mounted on the board, and
perform the post-mounting inspection for inspecting a state of a mounted component on the board by the head when the flag is set indicating that the post-mounting inspection is required.
