PROBLEM TO BE SOLVED: To provide an automatic water supply device capable of inexpensively having a second signal input means by using a control means of a signal input means, to shorten a developing period and to restrain a developing cost by eliminating the necessity of newly designing an exclusive control means, and to expand the second signal input means in the executed water supply device by simple work at an execution site. SOLUTION: This automatic water supply device has a water supply means for discharging water and cutting off the water, the signal input means for indicating water discharge and water cut-off to the water supply means, and a control means for controlling the water supply means by receiving a signal from the signal input means via a communication cable. A communication means receives the signal of the second signal input means, and is connected to the communication cable for connecting the signal input means and the control means. The signal from the second signal input means is also transmitted to the control means via the communication means. COPYRIGHT: (C)2003,JPO
