Document Type and Number:
WIPO Patent Application WO/2018/230171
Kind Code:
A1
Abstract:
The present invention ensures a size reduction and reduces the effect of magnetic flux produced in one magnetic drive unit on the other magnetic drive unit. This invention is provided with: a first magnetic drive unit having a first coil to which a drive current is supplied and a first magnet that is caused to rotate when the first coil is energized; a second magnetic drive unit having a second coil to which a drive current is supplied and a second magnet that is caused to rotate when the second coil is energized; a first drive lever operated by the first magnetic drive unit; a second drive lever operated by the second magnetic drive unit; a first shutter blade, which opens/closes an opening when the first drive lever is operated; a second shutter blade, which opens/closes the opening when the second drive lever is operated; a first lock mechanism for locking the first drive lever at a prescribed position; and a second lock mechanism for locking a second drive lever at a prescribed position. At least a part of the first lock mechanism and at least a part of the second lock mechanism are positioned between the first magnetic drive unit and the second magnetic drive unit.
