PROBLEM TO BE SOLVED: To provide a game machine which can easily renew the model. SOLUTION: Because a rotary body 100 with a plurality of symbols is equipped with electronic paper 98 to display a plurality of symbols by moving charged particles in an electronic ink layer interposed between a first substrate and a second substrate to change color, a plurality of symbols displayed on the electronic paper 98 can be renewed into new symbols. Accordingly, even in a case to renew a game machine, symbols on the rotary body 100 can be renewed into new symbols and parts exchange to replace a rotary body itself by a new rotary body is unnecessary, thereby making game machine renewal easier.
