PROBLEM TO BE SOLVED: To provide a game machine in which hours of use of a display device can be grasped and the display device can be recycled effectively.SOLUTION: When a liquid crystal panel switch is depressed shorter than five seconds (S31: No), a value of total hours-of-use data stored in a liquid crystal panel memory is confirmed through processing of S32 to S34, and the number of display LEDs to be lighted is changed through processing of S35 to S37. For example, when the value of the total hours-of-use data of the liquid crystal panel stored in the liquid crystal panel memory is 40,000 hours or longer (S32: Yes), all display LEDs 49, namely, a third LED, a second LED and a first LED are lighted all (S35-S37) and such a state is continued for five seconds (S38: No). Therefore, lighting of all the display LEDs allows an operator to grasp that the hours of use of the liquid crystal panel are 40,000 hours or longer, and determine whether the liquid crystal panel can be recycled. |
