Title: Display system for game arcade
Inventor: NOSAKA TOSHIYUKI
IPC: A63F7/02
Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a display system for a game arcade capable of confirming past operating states and grasping the variation of operating states in each game machine island in a short period of time. SOLUTION: A centralized control system stores the variation of operating states in a status memory. In order to confirm the variation of operating states in each game machine island, an operator inputs a displaying condition to the centralized control system when it displays a hall animation screen 6 and then touches a 'display' button 11. The centralized control system displays the variation of operating states stored in the status memory on a panel screen 7 in colors corresponding to the contents of the operating states on the basis of the display condition. As a result, since the variation of operating states is displayed in a layout showing game machine islands, the operator can confirm it in each game machine island through the variation of colors in a short period of time.
