PROBLEM TO BE SOLVED: To provide a game machine which enables stable serial transmission without increasing the processing load of a CPU and has a simplified circuit constitution.SOLUTION: A game machine includes an upstream circuit TR which receives drive data output in parallel from a performance control unit, and outputs it as serial data; a downstream circuit RV which receives the serial data output from the upstream circuit and drives a light emitter of a movable performance body to be turned on; and a movable connection body SL in which a plurality of conduction passages are stationarily maintained despite the movement of a movable part. The upstream circuit TR and the downstream circuit RV are connected without using a transmission line of a transfer clock. The upstream circuit TR repeatedly outputs the drive data received from the performance control unit in a self-running state.SELECTED DRAWING: Figure 6 |
