PROBLEM TO BE SOLVED: To reduce control load of a sub-control section.SOLUTION: A sub-control board 42 transmits command data of a "lottery request" to an upper LED control board 240. The upper LED control board 240, when receiving the command data of the "lottery request", executes substitute lottery processing of a requested type. Specifically, a one-chip CPU 241 of the upper LED control board 240 generates a random number and executes the substitute lottery processing, on the basis of the generated random number and a table related to the substitute lottery processing of a requested type in various tables stored in a RAM of the one-chip CPU 241 by loading processing. Then, the upper LED control board 240 returns the command data of a "lottery result notice" to the sub-control board 42 to notify the sub-control board 42 of the result of the substitute lottery processing. |
