In a component mounting machine comprising a mounting head that sequentially picks up electronic components from the individual component extraction positions of the component supply unit and sequentially mounts them on the printed circuit board, the component supply unit includes a tape cassette type component supply unit and a component extraction position bottom. Tilting-type component supply units each having a hole for detecting a component in a wall can be selectively mounted in parallel with each other in a plurality of rows, and the tilting-type components can be installed in a direction parallel to the tilt-type component supply unit at the rear end. The component supply unit has a mounting portion formed with a plurality of connection ports connected to an air source capable of supplying air to the component passage of the supply unit. Is provided with a movable body that is movable in conjunction with the mounting head along a guide shaft extending in the parallel direction of each of the component supply units, and the movable body acts on each feeding mechanism of the tape cassette type component supply unit.
