Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2015090413
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To disclose a content regarding a way to align a travelling position of a mechanical shutter and a rotation phase of a stepping motor, which are of importance for making a driving pattern of an electronic shutter highly accurately match a travelling pattern of the mechanical shutter, and efficiently travelling the mechanical shutter in high speed.SOLUTION: An imaging device comprises: a cover part having an opening part; a curtain mechanism that is held by the cover part, and is movable between a position where the opening part is blocked by a stopper of the cover part and a position where the opening part is not blocked; an actuator that actuates the curtain mechanism; and control means for controlling the actuator. The actuator has a rotor that has at least two poles magnetized, a first coil and a second coil. The curtain mechanism is configured to be energized to the stopper by force allowing the rotor to move to a rotation position with respect to the first coil and the second coil in a non-electrified state.
