Title:
LIGHT-SHIELDING BLADE, BLADE DRIVE DEVICE, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026448
Kind Code:
A1
Abstract:
One embodiment of this light-shielding blade is a light-shielding blade for an imaging device, wherein the light-shielding blade comprises a magnet having a hole part disposed along a center axis extending in one direction, and a blade body having a fixing surface facing one side in the axial direction. The magnet is fixed to the fixing surface on one side in the axial direction of the blade body. The hole part is recessed from the end part on the other side in the axial direction of the magnet to one side in the axial direction. The blade body has a through hole that passes through the blade body in the axial direction and connects to the hole part. The magnet has a facing part on the outer side in the radial direction of the hole part, the facing part being disposed facing the other side in the axial direction, and separated on the one side in the axial direction from the fixing surface. An adhesive that adheres the facing part and the fixing surface is disposed in the gap in the axial direction between the facing part and the fixing surface.
