PURPOSE:To give information to an operator with high efficiency, by delivering the designated information just for a prescribed time and in response to the feeding of a coin. CONSTITUTION:When an operator pushes only a push-button switch 3a, a computer 5 reads in a state under which the switch 3a is turned on. Then the computer 5 reads in the information corresponding to the switch 3a from a floppy disk and displays it on the screen of a CRT2. In addition, the computer 5 checks whether a timer 8 is counted up or not and then continues the processing if the timer 8 is not counted up yet. While the computer 5 finishes the display processing when the timer 8 is counted up. Finally the timer 8 turns off a power supply device 7. |
