PROBLEM TO BE SOLVED: To provide a game machine which can perform appropriate signal transmission from a control side to an accessory side.SOLUTION: In a configuration where a game board forming a game area is provided with a rotary display device, a slip ring 4101 is used for signal transmission to LED drivers 3302a and 3302b of the rotary display device from a lamp control board 1550. Then, the LED driver 3302a of the rotary display device is provided with a latch generation part 3302c. The latch generation part generates LAT on the basis of DAT outputted by the lamp control board 1550. Thus, the slip ring 4101 transmits 4 signals, GND, CLK, DAT, and 15V.SELECTED DRAWING: Figure 42 |
