摘要： In a lens barrier device, one barrier blade is arranged at a different height in the optical axis direction from another barrier blade, and a barrier base is provided with a regulating portion which is at the outer peripheral portion of an optical axis forward end side barrier blade and which regulates the position in the optical direction of the optical axis forward end side barrier blade, thus forming the lens barrier device as a unit. If rotation shafts for the barrier blades are formed on an external cover, deformation or the like would be generated when the external cover is assembled to the apparatus, resulting in an increase in the requisite drive force for the opening/closing operation. Hence, it is possible to prevent a suitable opening/closing operation from being hindered by such an increase in the requisite drive force.

摘要： An information recording/reproducing device includes an optical pickup and traversing means for moving the optical pickup in a radial direction of a disc-shaped recording medium. The optical pickup includes a splitter for splitting light emitted from a light source into transmitted light and reflected light, an objective lens for focusing the transmitted light onto the recording medium, a deflecting mirror for guiding the transmitted light to the objective lens, and a photo detector that detects light reflected by the recording medium. The light source, splitter, and deflecting mirror are arranged on the optical pickup such that a light axis extending from the light source to the deflecting mirror is slanted towards an inner periphery of the recording medium with respect to a direction perpendicular to a moving direction of the optical pickup. The photo detector is disposed at an inner periphery side of the recording medium relative to the light axis.
