Ž<P>SOLUTION: The disclosed Pachinko game machine is provided with: a main control part 21 for outputting a control command; an authentication part 202 for authenticating the main control part 201; and the peripheral part 203 for performing prescribed processing on the basis of the control command. When the control command is a losing command for making the peripheral part execute processing for the case that a drawing result during drawing is a losing, the main control part 201 adds authentication data for authenticating the main control part 201 to the losing command and supplies it to the authentication part 202. The authentication part 202 authenticates the main control part 201 using the authentication data added to the losing command, also adds an authenticated result to the losing command and supplies it to the peripheral part 203. The peripheral part 203 executes processing corresponding to the authenticated result added to the losing command. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
