In an electronic parts installation device, increasing throughput by brining parallel operation of motors, etc., to the maximum, and having high reliability by reducing contacts and/or interferences generating the parallel operations, an electronic parts installation head actuator (9), comprises a plural number of suction nozzles (115), each for sucking an electronic part to install it on a printed circuit board, a nozzle selector member (301) for selecting a predetermined suction nozzle from the plural number of suction nozzles (115), and an elevating device (101) for elevating the plural number of suction nozzles (115), wherein the nozzle selector member (301) has a permanent magnet for attracting the suction nozzle (115), which is biased in one direction by a spring (112), to the direction opposite to that one direction, and an excitation coil for neutralizing a magnetic force of the permanent magnet by applying current therein. |
