PROBLEM TO BE SOLVED: To prevent a bias in combining renditions to be performed in respective electric part control means by performing the renditions by the electric part control means at random. SOLUTION: The count value of a prediction random number counter 1 is counted-up by prescribed cycle. The contents of a last-time left stop pattern storage area are added to the count value of the prediction random number counter 1 when pattern change is started in a variable display device. The pattern number of a left stop pattern when the last-time pattern is variably displayed is stored in the last-time left stop pattern storage area. Besides, the contents of a last-time right stop pattern storage area are added to the count value of the prediction random number counter 1. Then the count values of the prediction random number counters 1 and 2 are read and adopted as prediction determining random numbers 1 and 2. A prediction rendition mode is determined based on the prediction determining random number 1. When the prediction determining random number 2 coincides with the same prediction judgement value and is made to be a big hit, the prediction rendition is performed in a mode being the same as that of the last-time prediction rendition.
