The present invention is intended to realize a hold posture inspection of a plurality of components sucked by a plurality of nozzle rows provided on a head with a single scanning operation, thereby reducing the time for the hold posture inspection and improving the accuracy thereof. In order to achieve such objections, the present invention includes: a head on which at least two nozzle rows are disposed, each of which includes at least one nozzle; a circuit board holding unit for holding a circuit board on which components conveyed by the head are mounted; and an inspection unit, provided on a moving path of the head from a supplying unit to the circuit board holding unit, for inspecting hold postures of the components held by the nozzles of the head and including sensors for posture inspection independent for the respective nozzle rows.
