摘要： A laser emission unit for use in an optical head performs a plurality of functions which are integrated. A laser beam from the laser emission unit mounted in a lens holder is emitted through an objective lens and is focused on an optical medium. A reflected beam from the optical medium returns through the objective lens and a diffraction grating to a signal detection circuit in the laser emission unit. Since the laser emission unit performs a plurality of functions, the space for various elements otherwise required in the optical head can be eliminated. The space for an additional light path for the reflected beam is also eliminated. Therefore, the size of the optical head is very small. Since the optical head can be assembled by using a small number of parts, the production costs can be reduced. Furthermore, the optical head can shield the noises by using the housing and/or the lens holder itself.

摘要： A projector with high safety is provided by directly shutting down the laser beam production when normal scanning of the laser beam is not carried out, thereby reducing exposure to the laser beam. For this purpose, the projector is provided with a laser beam source (10) that outputs a laser beam and modulates the laser beam in a beam form based on an image signal, a scanning unit (30) that scans the laser beam output by the laser beam source (10) at least in one-dimensional direction, a scan driving unit (50) that drive controls the scanning unit by a first force, a retaining unit (40) that stops and retains the scanning unit at a predetermined position by a second force, and a light shielding unit (70) that shields the laser beam from the scanning unit (30) that is retained by the retaining unit (40). The scan driving unit (50) releases the scanning unit (30) retained by the retaining unit (40), and drives it when the first force is larger than the second force. The retaining unit (40) stops and retains the scanning unit (30) at the predetermined position when the second force is larger than the first force.
