A projection display device includes a projecting portion which enlarges and projects light modulated by an imager; a projection port which is formed in a main body cabinet, and passes light emitted from the projecting portion; and a cover which covers the projection port. In this arrangement, the main body cabinet is formed with a first attachment portion for attaching the cover thereon in covering the projection port, and a second attachment portion for attaching the cover detached from the first attachment portion thereon.

A projection display device includes a terminal which is disposed on a surface of a main body cabinet, and a terminal cover which is attached to the surface of the main body cabinet to cover the terminal connected to a cable. In this arrangement, the terminal cover is formed with an opening portion on a surface thereof for passing the cable therethrough, the surface of the terminal cover facing upward when the projection display device is installed in a suspended state.

A projection display device includes: a leg section that supports a main body of the projection display device with respect to an installation surface on which the main body is installed; and a filter section that is disposed on a bottom of the main body and exposes a first air intake surface to the outside. In this arrangement, the first air intake surface is inclined with respect to the bottom surface of the main body in a direction that departs from the installation surface, and air flows into the filter section through a clearance between the first air intake surface and the installation surface.

A projector to which a ceiling suspension attachment is fixed. The projector accommodates an internal device. The projector is provided with an outer case including a bottom wall that defines an outer bottom surface and an inner bottom surface of the outer case. Insert nuts are arranged on the bottom wall. Each insert nut includes a threaded hole to which a first coupling screw is fastened and a second coupling screw can be fastened. The first coupling screw couples the attachment to the outer bottom surface of the bottom wall, and the second coupling screw is fastened to the threaded hole from a side opposite to the first coupling screw. The second coupling screw is fastened at least one of the insert nuts to couple the inner device to the inner bottom surface of the bottom wall.

A projector is provided with a lamp including an arc tube, which generates light, and a reflector. The reflector includes an inner surface that reflects light from the arc tube and an opposite outer surface. The arc tube and the inner surface define an inner portion of the lamp. At least the outer surface defines an outer portion of the lamp. A housing accommodates the lamp and includes an air inlet through which air is drawn in from outside the housing. An air mixing structure mixes a cooling current that has cooled the inner portion of the lamp with the air drawn into the housing through the air inlet. A cooling current guide structure guides the cooling current mixed with the air mixing structure to the outer portion of the lamp.

A video projector including a light source used to display an image, an optical component that differs from the light source, a power supply unit that supplies power, and a centrifugal fan including a rotation shaft and a blade that rotates about the rotation shaft. The centrifugal fan is a double intake fan that draws in gas from first and second axial directions, which are parallel to the rotation shaft, by rotating the blade and sends the gas outward in a radial direction from the rotation shaft. The centrifugal fan sends gas that has cooled the optical component and the power supply unit to the light source.

A projector apparatus equipped with a metal plate structure serving as a light shield against a light source and as a heat radiator is provided. The metal plate structure is arranged over the light source to hide the light source. The metal plate structure extends farther to a cooling fan and connects to the upper end of the air expiration face of the fan. The metal plate structure thus serves as the top plate of the baffle section of the exhaust duct of the fan for leading the air expired from the fan. The metal plate structure also serves as a shield plate, which can be connected to a grounded metal piece.

A duct was configured such that an incident side and an outgoing side of each of liquid crystal panels 34r, 34g, and 34b are formed with discharge ports r1 and r2, g1 and g2, and b1 and b2 to discharge the air from fans 41 to 43 through ducts 411 to 431, and at the same time, a PBS 28 for aligning the polarizing direction of the light from a light source lamp is formed with a discharge port p1 to discharge the air from the fan 43 through the duct 432, and an incident side discharge port b1 and an outgoing side discharge port b2 of the liquid crystal panel 34b corresponding to the blue light are formed with the ducts so as to discharge the air from the fans 43 and 41 which are different from each other. As a result, even when an amount of light per unit area of high luminance is increased, the liquid crystal panels and the polarizing plates and the PBS can be effectively cooled by three sets of the fans.
