In a solder printing inspection machine (100), an identification code and an inspection time of an inspection target board are accumulated in a memory in each time, and the accumulated data whose identification code is matched with that of the current inspection target board is searched. When the corresponding board is found, it is recognized that the board is extracted because of the defective board and the inspection target board is one that the extracted board is reintroduced. A graph in which pieces of information expressing the pieces of quality of the boards are arrayed in time series is produced based on each time of inspection result, and the graph is displayed on a monitor. In the pieces of data included in the graph, the data corresponding to the board that is recognized as the reintroduction is explicitly shown by a letter "R". |
