SOLUTION: The pattern display board 44 is provided with a sub-CPU 103 receiving pattern variation start command data and the like sent from an I/O interface 54 of the main board 41 through a bus-line 95. The sub-CPU 103 interprets the received command data and outputs information to a pattern examining device, and transmits variation pattern data and the like to a main CPU 100 for controlling a special pattern display device 8. |
