(54) Electronic component mounting apparatus


(57) The invention is directed to minimization of mounting time of each of electronic components by starting simultaneous operations of the suction nozzle in vertical movement and horizontal movement based on start delay of a vertical movement mechanism or horizontal axes of the suction nozzle. When the suction nozzle is to lower, CPU determines a lowering start position of the suction nozzle during its movement based on start delay time of a nozzle vertical movement motor for vertically moving the suction nozzle, that is, time (NL axis start delay) from the time when the CPU outputs an operation signal for the nozzle vertical movement motor until the time when the nozzle vertical movement motor actually starts operating, that is stored in RAM, and time from the time when the suction nozzle starts lowering until the time when the suction nozzle reaches a distance at its lowering speed. This realizes the earlier timing to start the lowering of the suction nozzle during the movement of the mounting head, that is, during the movement of the suction nozzle.
