Component information including operating parameters for numerical determination of an operation mode of an electronic component mounting operation unit and a change history of the component information are stored in a component information change history storage unit. A mounting error occurring during an electronic component mounting operation is detected, mounting error information relating to an occurrence situation of the mounting error is recorded, and a transition of the mounting error is displayed on a display unit. When the component information is changed, the past mounting error information in which the mounting error information relating to the mounting error occurring during the electronic component mounting operation for the electronic component as changed is associated with the past component information immediately before the change is stored in the past mounting error storage unit and displayed on a display screen. |
