ABSTRACT OF THE DISCLOSURE This invention relates to a cold/hot water discharging apparatus which is used for cold/hot water massage shower, and the like. In order to alternately switch and supply hot water of a predeter- mined temperature supplied from a hot water source to a discharge portion, a valve of a cold/hot water mixing tap is driven by a motor and is reciprocared in a pre-set period between a position where high temperature hot water is discharged and low temperature hot water is discharged. In each of the periods for discharging low/high temperature hot water, an optimum gain of this period is determined from the previous period and previous gain so as to shorten the discharge period of cold/hot water and to obtain a stable curve of the discharge hot water.
