    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.

    摘要： A pair of openings (302) symmetrically disposed around an optical axis of the reflector (412) is formed on a contact surface of a light-transmissive plate (301) and the reflector (412) and a cooling channel (340) for introducing cooling air to a source lamp (411) through the pair of openings (302) and a first and a second cooling channel shutters (350, 360) for shutting the cooling channel (340) when the case is detached from a projector (1) are provided on a case (300). The source lamp (411) can be efficiently cooled, so that the life of the source lamp (411) can be lengthened. Even when a light-emitting tube of the source lamp (411) is exploded while using the projector (1), the fragments of the light-emitting tube do not fall outside in exchanging the light source (413), and cooling efficiency of the source lamp (411) is not impaired.

    摘要： In embodiments of translucent object presence and condition detection based on detected light intensity, a light is emitted and directed at a first edge of a translucent object along its thickness to pass through the translucent object, such as a lens. An intensity of the light is detected proximate an opposing, second edge of the translucent object. A presence and/or a condition of the translucent object can then be determined based on the detected intensity of the light that passes through the translucent object, where the detected intensity of the light that passes through the translucent object is relative and indicates one of: the presence of the translucent object based on a lower intensity of the light, or the translucent object is not present based on a higher intensity of the light.
