<p><P>PROBLEM TO BE SOLVED: To make noise reduction and smooth driving of a rotating sweeper upon startup compatible with each other. <P>SOLUTION: When a start instruction is input for operation through an operation input section SW, an electric blower 2b and a rotating brush motor 83 are driven and controlled by giving a target controlled variable characteristic which makes the target controlled variable of each of the electric blower and the rotating brush motor a steady state while gradually increasing the variable while a prescribed period (t2) elapses after the electric blower 2b and the rotating brush motor 83 start up, respectively. Especially, a microcomputer 63 drives and controls the rotating sweeper electric motor 83 by giving the target controlled variable characteristic which makes the increase rate of the target controlled variable in a prescribed period (t2) nonlinear. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
