Abstract

PURPOSE:To make construction small and simple and facilitate controlling by constituting a movable part of a bobbin wound with coils and an optical mechanism part into one piece, and disposing this in the magnetic path movably in 3-axis directions. CONSTITUTION:A ring 11 is secured to the bottom surface of a yoke 14, and a ring 15 is secured to the top surface of a projecting part 14c. Holding members 12, 17 are secured to the rings 11, 16. A bobbin 15 is secured to the top end face of the projection 13b of the holder 13 of a lens 19, and its lower part is fitted into and held by the member 12. The four projections 13b are disposed by passing through the four projecting parts 14c of the yoke 14. The member 17 is fitted to the small diameter part 15a of the bobbin 14. An optical mechanism part 18 is adhered and secured to the part 15a. The movable part formed with the part 18, the bobbin 15 and the holder 13 in one piece is disposed movably in 3-axis directions between two pairs of orthogonal magnets 5. Thereby, the construction is made simple and control is made easy.
