摘要： An optical apparatus is disclosed which is capable of preventing degradation of image quality caused by an ND filter. The optical apparatus includes an aperture stop having an aperture variable in size, and an ND filter movable with respect to the aperture of the aperture stop, an actuator that drives the ND filter, and a controller that controls the actuator. The ND filter includes a part having a size that can fully cover a first aperture that is the aperture with the aperture stop being narrowed. The controller controls the actuator so that the ND filter is moved without a halt between a first position where the part is retracted with respect to the first aperture with the aperture stop being narrowed, and a second position where the part fully covers the first aperture in any stop operation.

摘要： The present invention relates to an optical instrument such as an optical axis deflecting device or an image stabilizing device having an optical member supported for rotation about a predetermined axis and rotated about the predetermined axis to thereby deflect the optical axis of passing light, moving means adapted to move in a direction along a plane inclined by a predetermined angle from a plane perpendicular to the predetermined axis to thereby rotate the optical member about the predetermined axis, and driving means for driving the moving means. With such construction, a driving force generated by the driving means acts on that portion of the optical member which is far from the rotational shaft thereof and as a result, a driving torque for driving the optical member can be enhanced without causing the bulkiness and higher cost of the device and an increase in consumed electric power.

摘要： A magnetic disc drive in which two magnetic heads, each of which has at least two magnetic gaps, are provided on a single carriage and radially spaced apart from each other by a first predetermined distance. A radially inner one of the two magnetic heads is tilted at a first predetermined angle toward a rotary shaft with which the magnetic disc is engaged, and a radially outer one of the two magnetic heads is tilted at a second predetermined angle away from the rotary shaft, thereby bringing the magnetic gaps provided on the inner and outer peripheral heads into contact with a recording/playback surface of the magnetic disc when the disc is rotated.
