PROBLEM TO BE SOLVED: To provide a mounting device adaptable to high density mounting, narrow pitch mounting, in-cavity mounting, and the like.SOLUTION: In a mounting unit for mounting an electronic component on a circuit board while holding the electronic component, a mounting nozzle for mounting the electronic component is supported by a shaft extending in a direction perpendicular to the circuit board and capable of moving in that direction and rotating around that direction. The shaft is driven by a voice coil motor, and motion of the shaft in that direction is regulated by a solenoid coil. The shaft is supported by a spline and a bearing at a position closer to a lower end of the shaft than the voice coil motor, when viewed from the solenoid coil.SELECTED DRAWING: Figure 7 |
