Document Type and Number:
Japanese Patent JP2023141533
Kind Code:
A
Abstract:
To provide a driving device and an optical device capable of efficiently obtaining thrust and reducing size and weight even when a movement amount in driving an optical member is large and the weight of a movable portion is large.SOLUTION: A driving device includes: a magnetic circuit unit 31 having a first magnet 45, a second magnet 46, a first yoke 47 that holds the first magnet 45 and the second magnet 46, and a second yoke 48 disposed between the first magnet 45 and the second magnet 46; a first coil 32A that is bonded to a first zoom lens 22A and corresponds to the first magnet 45; and a second coil 32B that is bonded to a second zoom lens 22B and corresponds to the second magnet 46. The magnetic circuit unit 31 drives the first coil 32A and the second coil 32B, and the thickness of the second yoke 48 is larger than the thickness of the first yoke 47.SELECTED DRAWING: Figure 10
