| 1. A component mounting apparatus comprising:
a supplying unit having a plurality of supplying parts for supplying components, said supplying parts being aligned in an
X direction;
a head configured to have at least two nozzle rows aligned in a Y direction orthogonal to the X direction, each of which comprises
at least one nozzle arranged in the X direction and configured to take out a component supplied from the supplying unit and
to convey the component;
a circuit board holding unit configured to hold a circuit board on which the component conveyed by the head is mounted; and
an inspection unit, which is disposed on a moving path of the head from the supplying unit to the circuit board holding unit,
configured to inspect a hold posture of the component held by the nozzle,
the inspection unit comprising:
a plurality of sensors for posture inspection, the sensors being arranged with respect to the nozzle rows, respectively, and
being arranged so that centers of fields of view of the sensors are aligned in the X direction; and
one lighting unit shared among the sensors, arranged for all nozzle rows and configured to irradiate a light beam to the head
at a time of posture inspection, the lighting unit having an entrance port of optical information, the entrance port being
shared among the sensors, for taking an image of the component held by the nozzle,
wherein the head is configured to move in the X direction to perform posture inspection such that a position in the Y direction
of each nozzle row arranged on the head and a position in the Y direction of the center of field of view of each sensor coincide
with each other.
