    摘要: An apparatus for controlling a stepping motor (11) used for driving a chemical pump includes a random access memory (16) for storing a minimum current value required for driving the chemical pump at each of divisional intervals of one cycle of the chemical pump, two photo interrupters (13, 14) for sensing an angular location of the stepping motor (11) corresponding to each of the intervals of the chemical pump, and a central processing unit (17) connected to the two photo interrupters (13, 14) for controlling the stepping motor (11) in accordance with the angular location of the stepping motor (11) sensed by the two photo interrupters (13, 14), the central processing unit (17) being so arranged that it uses the minimum current value required for driving the chemical pump at an angular location following the angular location sensed by the two photo interrupters (13 14).
