Title:
STALL OCCUPATION STATE NOTIFICATION SYSTEM
Document Type and Number:
Japanese Patent JP2011100441
Kind Code:
A
Abstract:
To provide a stall occupation state notification system that prevents "occupied" from being wrongly indicated even after a person who has been in a toilet stall leaves there.
When a user is sensed while a door 13 of a toilet 11 is closed, a display lamp 33 is kept on even if the user does not move for a long time and the user is not sensed by a person sensor 16. On the other hand, for one second after closing the door 13, a transmission side controller cancels a sensing signal from the person sensor 16. Consequently, when the person rushes out of the toilet 11 or an air group having a temperature difference enters the toilet 11 from the outside, an indicator is prevented from malfunctioning.
