<P>PROBLEM TO BE SOLVED: To achieve miniaturization and reduction of weight in a device for control of an optical element enabling image blur correction operation and removal operation when being housed. <P>SOLUTION: The device for control of the optical element has: a first moving member that is supported movably in a first direction perpendicular to an optical axis of an optical system relative to a supporting member; a second moving member that holds the optical element constituting the optical system and is supported movably in a second direction perpendicular to the optical axis and non-parallel with the first direction relative to the first moving member; an electromagnetic actuator that includes magnets and coils provided in one of the supporting member and the second moving member, and the other, and gives driving force for moving at least the second moving member by energizing the coils in the magnetic field of the magnets; and an insertion/removal driving mechanism that moves the second moving member in the second direction between an anti-shake driving position where the second moving member can be positionally controlled by the magnets and the coils and a removal position where the second moving member is out of a position control range by the magnets and the coils. <P>COPYRIGHT: (C)2011,JPO&INPIT |
