PROBLEM TO BE SOLVED: To precisely regulate ground beans in response to the kind of ground beans, the kind of a drink or a variation of the extraction condition, and accurately feed a suitable amount of the ground beans by measuring the volume of the ground beans, and stopping the feeding of the ground beans when the ground beans have reached a specified volume. SOLUTION: Beans, which are ground by a coffee mill, are fed into a measuring chamber 51 through an introduction section 5A. When a specified volume of the ground beans is fed into the measuring chamber 51A, an actuator plate 50E moves based on the pressure, and a switch 56F is turned on. When the switch 56F is turned on, a driving circuit stops the energization to a mill motor 60. After the mill motor is stopped, the driving circuit energizes the motor 60, and rotates a driving shaft 58 counterclockwise. By this motion, a piston 56D moves in the direction to a front lid 5B. Based on the movement of the piston 56D, the ground beans in the measuring chamber 51 are fed downward by pushing to open the front lid 5B, and are fed to a coffee extractor through a chute. |
