The first movable portion 414A can be moved in the X-axis direction by the interaction with the magnetic field generated by the magnetic field generated by the magnetic field generated from the right end face side of the fixed magnet portion 411 in the Y-axis direction in FIG. The second movable part 414B can be moved in the X-axis direction by interaction with the magnetic field generated by the second movable coil 416B of the second movable part 414B.
Accordingly, the amount of permanent magnets necessary for the linear motor drive mechanism 41 configured to move the first movable portion 414A on which the first head portion 3A is mounted and the second movable portion 414B on which the second head portion 3B is mounted is set for each. Compared to the configuration in which the fixed magnet portion 411 is provided for each of the movable portions 414A and 414B, the cost of the linear motor drive mechanism 41 can be reduced, and as a result, the cost of the component mounting apparatus 100 can be reduced. Can be planned.

In the above embodiment, the head portions 3A and 3B are mounted on both the first movable portion 414A and the second movable portion 414B. However, the present invention is not limited to this, and the first movable portion 414A and the second movable portion 414B are not limited thereto. It is only necessary that the head portion 3A (3B) is mounted on at least one of the second movable portions 414B.
That is, for example, as shown in FIG. 5, the linear motor driving mechanism 141 has the head portion 3A mounted on the first movable portion 414A, and the second movable portion 414B includes, for example, the imaging device 105 and the mirror unit (light guide mechanism). 8 may be mounted.

For example, in order to reduce the thickness of the mirror unit 8 in the Z-axis direction, it is preferable to reduce the mounting angle of each mirror and increase the number of reflections by increasing the number of mirrors.

Therefore, when imaging the electronic component P held by the plurality of suction nozzles 31 of the head portion 3A, the first mirror 81 is moved to the predetermined suction nozzle 31 based on the movement of the second movable portion 414B in the X-axis direction. The imaging device 105 and the mirror unit 8 can be moved in the X-axis direction so as to be almost directly below the held electronic component P. Thereby, it is possible to easily perform imaging of the electronic component P held by the plurality of suction nozzles 31 arranged in parallel in the X-axis direction. For example, when imaging of the electronic component P is not performed, the plurality of suction components Since it can be moved to a place where it does not interfere with the operation of mounting the electronic component P by the nozzle 31, a more attractive component mounting apparatus 100 can be provided.
That is, when the imaging device 105 is arranged on the stage of the component mounting device 100, the number of electronic component feeders 11 attached to the component supply unit 1 is limited, or the electronic component P is attracted by the suction nozzle 31.
