A component mounter which exchangeably holds rotary head 11 in head holding unit 21 is provided with Z-axis driving mechanism 51 that engages lever engaging piece 39 of the nozzle holder 12, which performs component pickup and mounting operations, among multiple nozzle holders 12 held on rotary head 11, from above and below with pushing down roller 54 and Z-axis lever 52 in order to lower and raise the nozzle holder 12. The interval between lever engaging piece 39(A) of first holder 12(A) that performs component pickup and mounting operation first and lever engaging piece 39(L) of last holder 12(L) that performs component pickup and mounting operation last is set at a wide interval at which engagement with Z-axis lever 52 is released, and the wide interval between lever engaging piece 39(A) of first holder 12(A) and lever engaging piece 39(L) of last holder 12(L) is used as a passage through which Z-axis lever 52 passes in an up/down direction when rotary head 11 is attached/removed to/from head holding unit 21. |
