Abstract: PROBLEM TO BE SOLVED: To surely prevent dust from being attached onto an objective lens and further prevent dust from entering an optical block. SOLUTION: A cover plate 45 is provided to cover a transparent aperture 24 of a lid member 21 that covers an objective lens 11 when an optical pickup section 12 is moved to an outer position at which the objective lens 11 is caused to be positioned at the outside of an optical disk mounted onto a disk rotation drive mechanism 3. An operating section 55 for moving the cover plate 45 away from the objective lens 11 is provided either at the lid member 21 or the cover plate 45. When the optical pickup section 12 is moved to the outside of the optical disk, the cover plate 45 is caused to be moved away from the objective lens 11 by means of the operating section 55, thereby causing the cover plate 45 to cover the objective lens 11 while avoiding abutment against the objective lens 11.

Abstract: PROBLEM TO BE SOLVED: To prevent optical characteristics from deteriorating due to dust and foreign objects and to miniaturize and make light an optical device by mounting optical parts to a hologram laser in one piece so that the lattice surface of the hologram laser can be sealed. SOLUTION: An optical base 11 formed by a flat plate has a mounting hole 11a at the mounting position of a hologram laser 12. The hologram laser 12 is mounted on the lower surface of the optical base 11 so that a lattice surface 12a opposes inside the mounting hole 11a. In this case, it is adhered over the entire periphery of a periphery step part 12b by such means as adhesion for the optical base 11. Optical parts 13 consist of a parallel flat plate, a filter, and the like and are mounted so that they are adhered to the upper surface of the optical base 11. The lower, open edge and the upper open edge of the mounting hole 11a are closed by the hologram laser 12 and the optical parts 13, respectively, so that the lattice surface 12a of the hologram laser 12 is closed by the optical parts 13 via the optical base 11.

Abstract: PROBLEM TO BE SOLVED: To provide a light source and an image display device having performance higher than that of conventional ones.
SOLUTION: In a light source device part 2, a white light LT 2 obtained by ionizing and light-emitting a gas 24 by a laser beam emitted from a semiconductor laser 10 is used as the light source. The light source obtained in this manner as the white light can be substantially treated as a spot light source, and has a uniform band level in a visible light band. An image display device is configured in a manner that a single color light for a color image is extracted from such white light and displayed. For the image displayed on the display device, pixels can be made small up to the same degree as those of the light source. As to the displayed single color light, luminous intensity balance become almost uniform without variations therein.
