摘要： An imaging apparatus includes an optical system, an image pickup device, an image blur correction mechanism, and a holding mechanism having a holding member and a state capable of being switched between a holding state where the holding member is engaged with the image blur correction mechanism so as to mechanically hold the image pickup device and a released state where the engagement of the holding member with the image blur correction mechanism is released, the holding mechanism being set to the holding state when the image blur correction mechanism is not operated. The holding mechanism has a positioning mechanism having an elastic member configured to bias the holding member to position the image pickup device from a held position where the image pickup device is held in the holding state to an original position where the image pickup device is to be electrically held by the image blur correction mechanism. A deviation eliminating operation in which the holding mechanism is set to the released state when the holding mechanism is set to the holding state is executed.

摘要： The magnitude of magnetic attraction generated between an electromagnetic coil and a magnetic metal member (or an amount of electric current flowed to the electromagnetic coil) is controlled depending on a direction of acceleration (acceleration caused by the gravity (a gravitational acceleration) and acceleration caused by shake (shake acceleration)) working on an imaging apparatus. This magnetic attraction moves a second slider (including a CCD and a first slider) as a whole toward the electromagnetic coil. This movement brings two inclined surfaces (or fourth and fifth surfaces) of a shaft hole 10d into contact with a second guide shaft with no gap being interposed in between, and keeps the this contact condition.
