Abstract: 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.
