When performing the device type changing operation with the change of the board type to undergo mounting, the component mounting device, which has a first mounting lane and a second mounting lane and which is structured so as to be able to select either an independent mounting mode or an alternate mounting mode, moves a mounting head of the mounting lane to and thereafter positions and fixes to a previously-set predetermined withdraw position [P] where entry of a portion of a body of an operator by way of an opening (19) formed in a protective cover (18a) can be prevented and where safety of the operator is not impaired even if a mounting head of a mounting lane on the other side has undergone collision. |
