Abstract

PURPOSE:To provide a device which saves an amount of water used and is excellent in reliability and safety, by a method wherein a device is provided with a load detecting substance which is reduced in an inner volume through the weighing of a load, and liquid which is sealed in the load detecting substance. CONSTITUTION:An attendance detector, including a load detecting substance 5 for detecting an attendance and for discharging water through a shower nozzle 2 only in case the attendance passes through a shower room 1, is set in the shower room 1. The load detecting substance 5 is constituted such that it is reduced in the inner volume resulting from the compression of a bag substance 6 through the weighing of the load when the attendance steps a footboard, and liquid such as water is sealed in the bag substance 6 and a water supply tank 10. If the footboard 7 is stepped and the bag substance 6 is compressed, a switching mechanism 17 operates to discharge water through a nozzle 2. This obtaines an object detecting device which saves an amount of water used and has an improved reliability and safety.
