Document Type and Number:
Japanese Patent JP2016122057
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a blade drive device and imaging device that are advantageous to thinness.SOLUTION: A blade drive device comprises: a blade 105 that moves in and out an optical passage route; a drive ring 103 that drives the blade 105; and a holding substrate that rotatably holds the drive ring 103. The drive ring 103 is formed of a thin sheet-like member having an engagement part engaging with the blade 105, and in the holding substrate, provided are an aperture part which penetrates in a thickness direction and through which light passes, and an abutting part which is provided so as to protrude toward an optical axis direction at a circumferential edge of the aperture part and with which an inner diameter part of the drive ring 103 comes into slide contact. The inner diameter part of the drive ring has a bending part that bends in the optical axis direction.SELECTED DRAWING: Figure 1
