摘要： A guide shaft and a guide portion movably guide a lens holder for holding a collimator lens (i.e. correction lens) in an optical axis direction. A stepping motor rotates a screw shaft arranged in parallel to the optical axis direction. A nut member converts a rotating movement of the screw shaft into a rectilinear movement of the optical axis direction. An urging spring urges the lens holder against the guide shaft and the guide portion. The lens holder is driven in the optical axis direction along the guide shaft by the stepping motor, with a first contact portion and a second contact portion of the lens holder being contacted with the guide shaft, and a third contact portion of the lens holder being contacted with the guide portion by an urging force of the urging spring. The optical pickup device having the above arrangement allows for stable driving of a correction lens.

摘要： A magnetic head (4) and a magnetic head holding member (41) are cantilevered by a joint member (40). The magnetic head (4) includes a head main body (5) attached to a free end and a supporting member (6) having a supporting member elastic portion (10). The magnetic head holding member (41) has an elastic spring portion (44) near the joint member (40) and is opposed to an information recording medium (1) with the supporting member (6) interposed therebetween. The magnetic head holding member (41) includes position holding portions (48) protruding toward the information recording medium. When the magnetic head (4) is in a first position where the head main body (5) is located close to or in contact with the information recording medium (1) so as to perform recording or reproducing, the position holding portions (48) contact a cartridge holder (49). This makes it possible to reduce the thickness of a magnetic head device and a magneto-optical recording/reproducing apparatus. Further, due to the reduction of the number of components, the price of a magneto-optical recording/reproducing apparatus can be lowered further.

摘要： The present invention is directed to a bi-axial pivoting type actuator having a first movable section, a second movable section supporting the first movable section, and backlining. A first conductive portion and a second conductive portion for independently applying a driving voltage to each of the first movable section and the second movable section are provided on the second movable section, in a state of being split by isolation trenches and being stabilized by the backlining provided under the second movable section. By providing such backlining, mutual stabilization of the first conductive portion and the second conductive portion in an electrically isolated state, and simplification of the production steps for the actuator are realized. By providing a mirror on the first conductive portion of the actuator of the present invention as such, it becomes possible to provide a bi-axial pivoting type mirror device through a simple production process.
