Abstract:
An imaging apparatus for forming an image of a subject on an image-forming surface, comprising:first stator electrodes arranged in a predetermined direction and extending in a direction crossing the predetermined direction; a second stator electrode arranged to face the first stator electrodes and extending in the predetermined direction; a third stator electrode arranged to face the first stator electrodes and extending in the predetermined direction so as to be electrically isolated from the second stator electrode; a first movable section having a first hollow space, the first movable section being provided with first movable section electrodes and a second movable section electrode, the first movable section being movable within a moving space in the predetermined direction, the moving space being define between the first stator electrodes and the second stator electrode, the first movable section electrodes being mounted to the first movable section to face the first stator electrodes and the second movable section electrode being mounted to the first movable section to face the second stator electrode; a second movable section having a second hollow space, the second movable section being provided with third movable section electrodes and a fourth movable section electrode, the second movable section being movable within the moving space in the predetermined direction independent of the first movable section, the third movable section electrodes being mounted to the second movable section to face the first stator electrodes and the fourth movable section electrode being mounted to the second movable section to face the third stator electrode; a first optical lens system having a first optical axis arranged in the predetermined direction within the first hollow space; a second optical lens system having a second optical axis arranged in the predetermined direction within the second hollow space; and a driving circuit configured to supply a first driving signal to the first stator electrodes, to supply one of a second driving signal and a first holding voltage signal to the second stator electrode, and to supply one of a third driving signal and a second holding voltage signal to the third stator electrode so as to move both or one of the first and second movable sections in the predetermined direction relative to the image-forming surface to control image formation on the image-forming surface.
