PROBLEM TO BE SOLVED: To propose a variation time setting technique that can be applied even in a pinball game machine with only one kind of special pattern and can reduce a required capacity of a ROM of a main control device.SOLUTION: A conventional variation time data table has a value with two bytes with respect to a variation time of one variation pattern. In a pinball game machine of the present invention, variation pattern data are formed from one byte and a setting counter value corresponding to bits of the one byte is stored in a time constant table (shown in a figure). A variation time is calculated by adding a setting counter value corresponding to a bit that becomes "1" in the variation pattern data, thereby reducing data capacitance of the variation time. Further, even in a model that comprises only one kind of special pattern, the required capacity of the ROM of the main control device can be saved.SELECTED DRAWING: Figure 12 |
