PURPOSE:To simplify operation, by using a microcomputer to drive a body in accordance with a prescribed program and display the driven state of the body. CONSTITUTION:A set signal from an operating section 3, a rotation signal from a rotational frequency sensor 13 and a signal from a flow rate detector 15 for a water tank 14 are entered into a microcomputer 12, which processes these signals in accordance with prescribed program to control a pump P for rotating a driven body 2 such as a mixer drum and show the state of the driven body on the display part 16 of the operating section 3. Since the drive of the body 2 is controlled in accordance with the prescribed program, operation is simplified. Since the state of the driven body 2 is shown, the total time of rotation and the amount of water in the tank 14 can be known. |
