摘要： A fluid supplying device having a peristaltic pump with a depression and delivery system that includes an elastic tube (17) for receiving fluid and an assembly of depressing members (15) for alternately constricting and relaxing the elastic tube. A drive shaft (10) connects the depression and delivery systems to an electric motor (24). A rotary member (21) is provided on the drive shaft to rotate with the drive shaft and a plurality of discharge-amount transmitting devices (22) are provided on the rotary member in such a manner that the distances between the discharge-amount transmitting devices can be changed as desired. A detector (23) is disposed at the position of passage of the discharge-amount transmitting devices for detecting the discharge-amount transmitting devices and a switch (40) is connected between the detector and the electric motor to deenergize the electric motor.
