PURPOSE:To urge the self management of game time on a person who plays a game by measuring the elapse of time from time when a system is switched to a game mode, namely, game time, by a timer and displaying it on a screen at all times. CONSTITUTION:When an input signal from a game machine selection switch comes, the system is switched to the game mode through a switch circuit 2, and the game time timer Tg is started. When the game mode continues, an elapse time message is superimposed to CRT 5 at every 30 minutes in accordance with the value of the timer Tg. The display is eliminated after it is executed only for prescribed time. When game time Tg becomes 15 minutes before a maximum value Tmax (two hours, for example), which is previously set, the alarm message of 'It will be two hours soon. Let's stop playing a game', for example is superimposed and displayed on CRT 5. When game time becomes Tmax=2 hours, a power switch 12 is turned off, and the power of a television device is switched off. |
