<p><P>PROBLEM TO BE SOLVED: To enable a caretaker to certainly understand a change in a presence/absence state of each dwelling unit without troubling the caretaker to continuously watch a display showing the state at all times. <P>SOLUTION: A display section 14 is blinked in a first color when a presence state of a dwelling unit is changed to an absence state while the display section 14 is lit in the first color indicating a presence of an inhabitant. When a corresponding dwelling unit is selected in a selection operation section 15, the display 14 is lit in a second color. In contrast, the display section 14 is blinked in the second color, when the absence state of the dwelling unit is changed to the presence state while the display section 14 is lit in the second color indicating an absence of the inhabitant. When the corresponding dwelling unit is selected in the selection operation section 15, the display section 14 is lit in the first color. Thus, a presence/absence display system enables a caretaker to certainly understand a change in the presence/absence state because blinking of the display section indicating the presence/absence state clearly shows that the presence/absence state is changed and the presence/absence state after the change is displayed when the caretaker selects the dwelling unit corresponding to the blinking display section 14. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
