摘要： To provide an optical assembly capable of enhancing black level display while preventing deterioration of a WV film, and a projector assembled therewith, optical compensation elements are disposed before and after liquid crystal light valves, so that an unintended phase difference generated on the incident and emission sides of the liquid crystal light valves for individual colors is eliminated by adjusting the rotational positions of the optical compensation elements, thus enabling an enhancement in the contrast of a color image displayed on a transmission screen member. In case of B light including ultraviolet light in part, the optical compensation element is disposed at the subsequent stage of the liquid crystal light valve, so that as compared with when the optical compensation element is disposed at the preceding stage of the liquid crystal light valve, the optical compensation element can be reduced or prevented from deteriorating with age, thus enabling the contrast of image display to be maintained over a long period of time.

摘要： A projector is provided in which the production of an outer casing is facilitated, cooling efficiency is maintained well, and the outward appearance is preferable. A dustproof ventilating member is mounted in a clearance formed between the rim of an opening of a front casing forming an outer casing, and a projection lens. For this reason, cooling air can be reliably drawn into a device via the ventilating member. Since this eliminates the necessity for forming a meshed air inlet in the outer casing, the production of the outer casing is facilitated, and the manufacturing operation of the projector is easily performed. Moreover, cooling efficiency is maintained well, and the outward appearance is made preferable.

摘要： A projector, which has a main body and a plurality of feet protruding from the main body to support the main body, includes a first adjuster that adjusts stepwise the amount of protrusion of at least one of the plurality of feet, and a second adjuster that infinitely and finely adjusts the amount of protrusion of at least one of the plurality of feet. The position of a projection image of the projector can be easily and speedily adjusted by coarsely adjusting the amount of protrusion of the foot by the first adjuster, and then making fine adjustment by the second adjuster.

摘要： The invention provides a projector capable of easily replacing and efficiently cooling a light source, and capable of facilitating a reduction in the size of the projector. An exhaust fan adjacent to a light source lamp is mounted to a replacement cover so as to be removed from the main body of the projector together with the replacement cover. For this reason, by only removing the replacement cover, the light source lamp can be easily attached and detached together with the replacement cover unit. In addition, since it is not necessary to separately secure a special space for sliding the replacement cover unit, other components except the exhaust fan can be disposed closely to the periphery of the unit, and the size of the projector can be further reduced. Furthermore, when the replacement cover is closed, the exhaust fan is positioned closer to the replacement cover unit, so that a light source device in the unit can be efficiently cooled.

摘要翻译： 本发明提供了能够容易地更换和有效地冷却光源的投影仪，并且能够有助于减小投影仪的尺寸。 与光源灯相邻的排风扇安装到更换盖上，以便与更换盖一起从投影机的主体移除。 因此，通过仅移除更换盖，可以更换盖单元容易地安装和拆卸光源灯。 此外，由于不需要分开固定用于滑动替换盖单元的特殊空间，所以除了排气风扇之外的其他部件可以紧密地设置在单元的周边，并且可以进一步减小投影仪的尺寸。 此外，当更换盖关闭时，排气风扇位于更靠近更换盖单元的位置，从而能够有效地冷却该单元中的光源装置。

摘要： To provide a projector in which the position of a handle can be reliably maintained even when a housing and the handle are made of different materials. In a projector, the position of a handle is maintained with projections formed in the handle and contact portions of a lower casing being in contact with each other, and both the projections and the contact portions may be made of a same kind of material, such as resin. Therefore, there is no fear that one of the projections and the contact portions will undergo localized wear. Even when the lower casing is made of metal and the handle is made of resin, the handle can sufficiently withstand repetitive operations, and the position thereof can be reliably maintained.
