An electronic component placement machine and an electronic component placement method are disclosed. A takeout and transfer head, provided on rotary chip takeout and transfer mechanism, removes a chip from a feeder and flips it. A placement head receives the flipped chip and places it onto a board. An image of the chip at a pre-centering recognition position is captured during a takeout and transfer operation, during which the takeout and transfer head transfers the chip to the placement head at a receiving position, so as to recognize the position. Based on this positional recognition result, the chip and the placement head are positioned by controlling a placement head driving mechanism. Moreover, the takeout and transfer head is rotated to a position which does not hinder image capturing of the electronic component for placement positioning.

An electronic component mounting apparatus for determining whether or not a nozzle replacement operation is successfully performed. A horizontal array of nozzles are accommodated in the holder in a nozzle stocker, and a light emitting device and a light receiving device are arranged so that the light path between both runs above the nozzles. The nozzle stocker is arranged in a travel path of a feeding head. The nozzle mount of the feeding head returns a used nozzle into the holder or mounts a new nozzle thereon. When any nozzle remains lifted from the holder intercepting the light path, a returning operation of the used nozzle is determined to be a failure. When a nozzle replacement is performed, its success or failure is reliably determined by detecting a intercepting height of light and release height of light by the nozzle and nozzle mount, respectively.
