PROBLEM TO BE SOLVED: To restrain a wrong operation to prevent an illicit act based on the dividing of interruption and to efficiently execute various stage effects by controlling a pattern display board, a sound control board and an illumination control board through a command processing board on the basis of the command from a main board. SOLUTION: A main board 14 comprises a main CPU 18 for generating an interruption, for example, every 2 ms, and it is connected to a command processing board 50 connected to an illumination control board 28, a pattern display board 30 and a sound control board 58, and a command 35 consisting of a 2-bite numerical value is transmitted from the main board 14 according to first and second commands. When the command processing board 50 receives, for example, the first command, it generates a display control signal 36 for scrolling a special pattern for a prescribed time to the pattern display board 30. It also generates a sound control signal 37 for instructing the repeat of a prescribed melody to the sound control board 58, and an illumination control signal 38 for instructing the lighting of a fixed pattern to the illumination control board 28.
