PROBLEM TO BE SOLVED: To set a dilution ratio in a simple manner with high accuracy by providing a divider means which divides reference clock corresponding to input data to output divided clock, and controlling a raw material feed motor for driving a raw material feed pump based on drive signals corresponding to the frequency of the divided clock. SOLUTION: There are provided an encoder 2, in which numerical values inputted from an input circuit 1, which has a numerical value input key such as ten-key pad and a memory into which inputted numerical values are stored, are received to output code signals of 8 bits, and a reference clock oscillating circuit for outputting reference clock. And code signals are inputted from the encoder 2 by means of a divider circuit 4 so that reference clock of 10kHz is divided at a predetermined dividing ratio of maximum dividing ratio of 512 or less to output a drive signal from a driver circuit 5 corresponding to the divided clock. A raw material feed pump is actuated by a stepping motor 6 to feed raw material from a box stored bag so that a drink having a predetermined dilution ratio can be supplied. |
