PROBLEM TO BE SOLVED: To display whether a carried bonus is in the duration of being carried or not at energization with a simple constitution. SOLUTION: When a slot game machine is energized, a sub-CPU (Central Processing Unit) makes a liquid crystal display device display an initial image. The sub-CPU responds to a signal input from a main CPU to determine whether a BB flag is written in a nonvolatile memory or not. Thus, it is determined whether the BB is in the duration of being carried or not at the energization. When the BB is not in the duration, the sub-CPU reads out demonstration image display data from a sub-ROM (Read-Only Memory) with a first rate (> a second rate) to download it to a sub-RAM (Random-Access Memory). When the BB is in the duration, the sub-CPU reads out the display data from the sub-ROM with the second rate (< the first rate) to download it to the sub-RAM. Finishing downloading, the sub-CPU makes the liquid crystal display device display the demonstration image. COPYRIGHT: (C)2009,JPO&INPIT
