Abstract: A position controller for an optical element includes a movable member and is supported by a support member to be movable from an anti-shake driving range to a removed position, an image-shake correction driver, and an insertion/removal operational member. The insertion/removal operational member includes a first press portion which presses the movable member from the anti-shake driving range to the removed position by the insertion/removal operational member moving from an insertion position to the removed holding position, a second press portion which presses the movable member to the anti-shake driving range by the insertion/removal operational member moving from the removed holding position to the insertion position, and a displacement prevention portion which allows the movable member to move within the anti-shake driving range and prevents the movable member from moving beyond the anti-shake driving range when the insertion/removal operational member is in the insertion position.

Abstract: A position controller includes a movable member which holds the optical element and supported by a support member to be linearly movable from an anti-shake driving range in which the optical element is positioned on an optical axis to a removed position outside of the anti-shake driving range, an electromagnetic actuator including first and second coils supported by the support member and first and second magnets supported by the movable member, and an insertion/removal operational member. When the movable member is in the anti-shake driving range, the first and second magnets face the first and second coils, respectively. The first and second magnets are arranged on opposite sides of a removing-direction center line passing through a center of the optical element in a moving direction of the movable member so that a distance between magnetic-pole boundary lines of the first and second magnets increases toward the anti-shake driving position.

Abstract: A photographic device, includes a shake detector, a shake mitigator, a first commander, and a shake controller. The shake detector detects a device shake, that is, a shaking of the photographic device. The shake mitigator mitigates the effects of the device shake to reduce an image shake that is a shake of a photographed subject image. The first commander commands the photographic device to photograph the subject image. The shake controller controls the shake mitigator so that the shake mitigator refrains from mitigating the effects of the device shake from the point when the first commander commands the photographic device to photograph the subject image, until the point when photographing the subject image commences.
