CONSTITUTION:A base material 4 where a tray 5 for storing electronic components to be supplied this time are placed is lead onto one elevation table T1 out of a plurality of elevation tables T1 and T2 and a component take-out head 17 picks up electronic components from the tray 5 on one elevation table T1 in a component supplying area. At the other elevation table T2, the base material 4 where the tray 5 for storing electronic components to be supplied next time are placed are lead out. Then, the switching of the tray 5 is completed extremely quickly by simply changing the elevation table in the component supplying area from one elevation table T1 to the other elevation table T2. |
