Filed: 2002-10-10
Abstract: <P>PROBLEM TO BE SOLVED: To lessen the processing load of the main control substrate of a pinball game machine and increase the degree of processing freedom of the pattern control substrate.  <P>SOLUTION: The pinball game machine is built to start to variably display each pattern when image display command is transmitted from the main control substrate 30. The pressing of the variable abbreviated button 25 is effective from the time when the image display command is transmitted to 0.5 second prior to the time when the left special patter stops. Thus, when the image display command is transmitted, the varying of the special patterns starts. The main control substrate 30 does not need to manage whether or not the image control substrate 32 has started to vary the special patterns. Whether or not the special pattern during the varying process has stopped can be evaluated by the value of the variable time code. When the image control substrate 32 receives a variable abbreviated code, it forces to stop the left special pattern at time 0.5 second after receiving the code. Processing after stopping the left special pattern, that is, processing during a period from the time when the left special pattern stops to the time when the center special pattern and the right special pattern stop is the same to the processing conducted during the time when the left special pattern is not forced to stop.  <P>COPYRIGHT: (C)2003,JPO
