PROBLEM TO BE SOLVED: To provide a discharge quantity control device for a peristaltic pump capable of providing a stable dispensing accuracy even when dispensing quantity is very small. SOLUTION: The control device 1 has a peristaltic pump 10 with a plurality of rollers 21 rotatingly moving on a rotor 20, a motor 50 rotating the rotor 20, a CPU 42 controlling the motor 50, and a memory 43 storing data on discharging quantity corresponding to the rotating position of the rollers 21. The CPU 42 grasps the present rotating position of the rollers 21, refers to the data in the memory 43, and calculates the rotating angle of the rollers 21 for a desired quantity of discharge by the pump 10, thereby controlling the motor 50 based on the calculation result and rotatingly moving the rollers 21.
