PROBLEM TO BE SOLVED: To provide an automatic water-discharge controller capable of making precise water-discharge control by corresponding to the movement such as a forward movement of a hand to the water-discharge controller, a hand washing and a backward movement of the hand or the like of a user in the water discharge controller making use of an object sensor. SOLUTION: When water is not discharged, the first electromagnetic wave beam 23 is emitted to the first direction facilitating the detection of the forward movement of the hand 10 from a microwave motion-body sensor 22. When the forward movement of the hand 10 is detected by the first electromagnetic wave 23, the water discharge starts and, at the same time, the second electromagnetic wave beam 31 is emitted to the second direction facilitating the detection of the movement of scattering water 34 during the hand washing and having difficulty in making detection of a stream 30 naturally flowing out from a faucet 21. When the movement of the scattering water 34 can't be detected by the second electromagnetic wave beam 31, the water discharge stops. COPYRIGHT: (C)2006,JPO&NCIPI
