Abstract
Two plane parallel plates, orthogonally intersecting each other, are provided in front of a CCD device. The plane parallel plate is supported by its two ends which are deviated from an optical path. Each end of the plane parallel plate includes an armature made of soft electromagnetic iron, and two electromagnets are provided in the optical axis direction, while sandwiching each armature. By the on/off state of the two electromagnets, the armature can control the optical device in three angled positions, thus the optical device can have three shift positions with respect to the optical axis. Therefore, by virtue of the optical devices, an optical path can be determined by selecting a shift position of said optical device from nine shift positions (3.times.3).
