PURPOSE:To control an extraction amount by a simple construction in a manner such that means for opening and closing a plurality of outlets connected to a distribution container is closed by one rotating direction of a motor, the outlets sequentially opened by a cam by a rotation in the opposite direction are detected and the motor is controlled so as to drive or stop. CONSTITUTION:A plurality of outlets 2 to 5 formed on a distribution container l of an extraction drink are opened or closed by piston heads 6 to 9 and piston rods 10 to 13. The function of outlets 2 to 5 is usually energized in the open direction by springs. By an instruction of a control circuit 66, a motor 64 is rotated in a predetermined direction and all of the outlets 2 to 5 are held in a locked state by lock means. The motor 64 is rotated in the opposite direction, a desired number of the outlets 2 to 5 is opened by detecting means, and the drink is discharged by a distribution cam 60. Thus, the extraction amount can be adjusted as desired by a simple apparatus. |
