Title: Game machine
Inventor: NASU TAKASHI
IPC: A63F5/04
Filed: 2008-12-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a game machine which enables the transmission of one command preferentially to other commands.  <P>SOLUTION: The game machine is equipped with a power recovery command buffer in addition to a command buffer to keep a command (e.g. power recovery command) required to be transmitted preferentially to other commands set on the power recovery command buffer. In a command output processing (S21), when the command to be transmitted to the power recovery command buffer is already stored, the command to be stored into the power recovery command buffer is transmitted preferentially to the commands to be stored into the command buffer. As a result, if any command is desired to be transmitted to a sub control board preferentially to other commands, it is stored into the power recovery buffer and can be transmitted to the sub control board preferentially to other commands to be stored into the command buffer. In other words, this enables the transmission of one command preferentially to other commands.  <P>COPYRIGHT: (C)2009,JPO&INPIT
