To facilitate a work for feeding components by connecting a new component containing tape to a component containing tape under use currently.
The component management unit of a component mounter arranged to introduce a component containing tape containing a large number of components to a component take-out position and to mount components taken out from the component containing tape at the component take-out position comprises a means 35 for calculating the remaining number of components contained in the component containing tape, and a mounting control means 34 for setting a criterion value corresponding to the remaining number of components when the remaining length of the component containing tape under use currently becomes suitable for connecting a new component containing tape, and stopping operation of the component mounter to bring about a connection waiting state at a moment in time when the remaining number of components calculated by the remaining number calculating means 35 becomes lower than the criterion value.
