Water supply system for developing apparatus

A rinsing water supply system for supplying rinsing water to a rinsing unit in which a photosensitive material is rinsed, comprising:

• water supply passage means for supplying water from a water source to said rinsing unit;
• first solenoid valve means for opening and closing said water supply passage means;
• monitoring means for monitoring a level of contamination of said rinsing water in said rinsing unit;
• and
• optical signal transmitting means, disposed along and integrally with said water supply means, for transmitting light signals from said monitoring means to said first solenoid valve means to operate said solenoid valve means in response to said level of contamination.

A rinsing water supply system for supplying rinsing water to a rinsing unit in which a photosensitive material is rinsed, comprising:

• water supply passage means for supplying water from a water source to said rinsing unit;
• branched water supply passage means branched from said water supply passage means, through which said water flows, for diluting contaminated rinsing water;
• means for draining said contaminated rinsing water from said rinsing unit;
• means for diluting said drained contaminated water:
• first solenoid valve means for opening and closing said water supply passage means;
• second solenoid valve means for controlling an amount of water to flow through said water supply passage means and said branched water supply passage means, to supply said water to rinse said photosensitive material in said rinsing unit and to mix and dilute said contaminated and drained water in said diluting means;
• monitoring means for monitoring a level of contamination of said rinsing water in said rinsing unit;
• and
• optical signal transmitting means, disposed along and integrally with said water supply means, for transmitting light signals from said monitoring means to said first solenoid valve means to operate said solenoid valve means in response to said level of contamination.
