    摘要： A display device (100) of the present invention has a first switch (3) and a second switch (4) on an upper surface of its casing, and includes a control circuit (18) for controlling the first switch (3) and the second switch (4) and a light source (19) inside the casing. The control circuit (18) performs control so that the light source (19) is turned on when the second switch (4) is pressed after a predetermined period of time has passed from when the first switch (3) was pressed. Thereby, the display device (100) of the present invention prevents entering of a person into a projection area before projection of video, and controls inadvertent start-up.

    摘要： Disclosed herein is a laser projection device which can keep the colors of red, blue, and green laser beams constant even in high ambient temperature. The laser projection device includes a red laser light source which emits a red laser beam, a temperature sensor for detecting the temperature of the red laser light source, and a radiating unit for radiating heat from the red laser light source to the outside based on the temperature of the red laser light source detected by the temperature sensor.

    摘要： Disclosed is a compact optical pick-up head apparatus suitable for mass-production, which comprises a light radiation source, an element composed of photodetector split into a plurality of regions and integrated on the same base, an objective lens for focusing a beam from the above source on an optical disk, a blazed hologram integrated to the support member of the lens, a means for driving the support member to which the objective lens and blazed hologram are integrated in response to an output as servo signal output from the photodetector which receives a diffracted beam produced in such a manner that a return beam reflected or diffracted by the optical disk is incident on the objective lens integrated with the above hologram. The optical pickup apparatus according to the present invention employs a region-split-type phase hologram in which a pair of Flesnel zone plate-like patterns, by which a plurality of diffraction wavefronts having a different focus and the same diffraction order are produced outside an optical-axis, are non-superimposedly formed. The above hologram can be blazed with a pinpoint accuracy by lithography using a few mask patterns synthesized by a computer, and further a more preferably blazing can be realized by the combination of the ion beam etching and the lithography. Accordingly, not only noise caused by an unnecessary diffracted beam component but also the offset of a servo signal can be restrained and the size of the objective lens can be reduced by the integration of the entire optical system, which greatly contributes to the superminiaturization of an optical head.
