PROBLEM TO BE SOLVED: To provide a game machine which can simplify wiring inside the game machine and improve accuracy of synchronization control of a device and an accessory to be controlled.SOLUTION: Two circuit boards where a plurality of LED are arranged on a straight line are arranged face to face, and two circuit boards and a motor driver of a rotary display device which rotates the circuit boards with an LED arrangement direction as a rotation axis and generates an afterimage are multistage-connected to a lamp control board 1550. In the multistage connection, by using a three-line system synchronous serial interface of a clock signal, a data signal, and a latch signal, wiring can be simplified, and synchronization control of the circuit boards and the motor from the lamp control board 1550 is possible.SELECTED DRAWING: Figure 42 |
