Abstract
An electronic endoscope system has a video-scope, a video-processor, and a liquid supply apparatus. The video-scope has a liquid transmitting tube for spouting liquid from a tip of the video-scope, and is detachably and electrically connected to the video-processor. The liquid supply apparatus is electrically connectable to the video-processor, and has a container for storing liquid and a liquid supplier that supplies the liquid in the container to the liquid transmitting tube. A liquid jet performance member for spouting the liquid is provided on the video-scope. A liquid jet performance detector detects operational status of the liquid jet performance member, and a liquid jet performance transmitter feeds a control signal regarding the operational status of the liquid jet performance member to the liquid supply apparatus. The liquid supplier supplies the liquid in the container to the liquid transmitting tube in accordance with the control signal.
