Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 2002-04-30
Abstract: <P>PROBLEM TO BE SOLVED: To lighten the processing burden of a game control means on notice rendering performed using a plurality of rendering control means and to prevent a synchronization discrepancy in the notice rendering.  <P>SOLUTION: A display control means determines whether to perform notice rendering, and the kind of notice upon receiving a display control command of variable pattern specification from a main board. In the case of performing notice rendering, a lamp control command and a sound control command indicating the kind of notice rendering are transmitted. An emitter control means performs rendering with a lamp/LED in response to receiving a lamp control command indicating the kind of notice rendering, and a sound control means performs rendering with a lamp/LED in response to receiving a sound control command indicating the kind of notice rendering. The control burden of the game control means is thereby lightened, and synchronous notice rendering can be performed.  <P>COPYRIGHT: (C)2004,JPO
