A projection display device includes: a housing; a fan disposed within the housing, the fan having a vane portion and a fan case accommodating the vane portion so as to be rotatable; and multiple vibration-proofing members having at least one of elasticity and viscosity, the vibration-proofing members being disposed at multiple positions in the circumferential direction of the perimeter face portion of the fan case surrounding the vane portion around the rotational axis of the vane portion, such that the vibration-proofing members are introduced between the housing and the fan case.

Projection display device

A projection display device may include a housing which can be placed on a placing face with a lower face portion thereof distanced from the placing face; a fan, disposed within the housing, to suction from a first air inlet formed in the lower face portion; a filter detachably provided to the housing the as to close off the first air inlet; and a filter replacement access lid detachably provided to the housing so as to cover the filter closing off the first air only from the placing face side, with a second air inlet for suctioning of the fan provided in the filter replacement access lid; wherein the filter replacement access lid may be formed so as to protrude toward the placing face side from the lower face portion; and wherein the second air inlet may be formed in a face of the filter replacement access lid intersecting the lower face portion.

A cabinet of a projection type display unit includes a base cabinet on which main component parts are mounted, and a top cover made from sheet metal which is mounted so as to cover the base cabinet, wherein a rear face portion of the top cover is formed in the shape of a curved surface being laid-down U-shaped in side view. The U-shaped curved surface is formed on an ergonomic basis, so that the rear face portion can be gripped securely even with one hand. On the back side of the top cover, bosses are integrally formed by use of a resin which is a different material from the sheet metal of the top cover, and the base cabinet and the top cover are fixed by fastening screws to the bosses from the base cabinet side.

Projection type display unit having a curved housing

A projection type display device, in which efficient cooling is performed in a remarkably silent manner, includes: a light source unit; an optical unit for modulating illumination light output from the light source unit based on input image information; two power source sections and; a box for housing the optical unit, the light source unit and the power source sections; and a cover member for entirely covering at least an upper surface of the box, wherein an outlet for externally exhausting air in the box by using axial fans is provided only on a bottom side of the box. Liquid crystal panels that are held by the optical unit frame absorb the illumination light from the light source unit and thus have different increased temperatures. Cooling air blown through an outlet of a sirocco fan that is directly connected to the optical unit frame is divided by a cooling air reservoir and a distribution sheet into predetermined air quantities in accordance with the temperatures of the liquid crystal panels so that the quantities of air obtained by the division are directly sent to the liquid crystal panels.

Projection type display device

A projection display device includes an optical unit, a cooling fan for cooling the circumference of light valves of the optical unit, and an exterior cabinet accommodating the optical unit and the cooling fan. The cooling fan is in the form of a sirocco fan. Cooling air of the cooling fan is brought to the circumference of the light valves through a duct, and is distributed by air-quantity controlling means arranged in the duct for effective cooling thereof.

Projection display device comprising means for cooling an optical unit and air quantity controlling means

A display apparatus of the projection type is improved in that, when a lamp valve breaks or is to be replaced, glass fragments and so forth thereof are prevented from being scattered into the inside of an outer housing of a projector apparatus through a cooling air intake port in a portion of the outer casing below the lamp valve and a comparatively small number of cooling fans are used to reduce the size and the weight of the overall display apparatus while optical modulation elements, a light source element and so forth can be forcibly cooled in a high efficiency. Cooling air blasted from an air blasting fan is blasted through an air blasting duct to three spatial optical modulation elements, a PS conversion element and a discharge lamp to forcibly air-cool the elements. A lamp box in which the light source is accommodated and which is removably mounted in an outer housing has a cooling air intake port through which cooling air is taken in to the light source. A shutter mechanism automatically opens the cooling air intake port when the lamp box is mounted in position into the outer housing, but automatically closes up the cooling air intake port when the lamp box is removed outwardly from the outer housing.

Image display apparatus of the projection type

A projector device, which is simple and small and able to display images brighter and also able to improve the usefulness considerably. The effective reflecting lights of the mirror deflection type light modulators are focused into images at the position right in front of the projection lens, and the effective reflection lights are partly turned and focused on the two-dimensional position detector means for detecting the vertical and horizontal positions of the formed images. Then, based on the detected information from the two-dimensional position detector means, the mirror deflection type light modulators are finely displaced in the vertical and horizontal directions, or the mirror deflection type light modulators are finely displaced in the vertical direction and the synthesizing mirror means is finely displaced in the direction of focal length, so that the positions of the effective reflection lights of at least two mirror deflection type light modulators are adjusted, therefore the discrepancy of the positions among the colors can be effectively corrected and the image quality can be considerably improved.

A glasses type head mounted display apparatus for seeing a virtual image through left and right lens systems provided with corresponding left and right display portions displaying left and right pictures, respectively. The display apparatus includes left and right slide mechanisms for moving the respectively left and right display portions on the main point axes of the lens systems and on segment lines through the central points of the left and right lens systems and focuses of the left and right lens systems so that the user sees through the left and right lens systems a virtual image synthesized with pictures of the left and right display portions.

Glasses type display apparatus

A disk magazine (1) for containing a plurality of disks (8) includes a detachable lid (4) for covering its disk outlet (2), enabling to take out the disks, a plurality of disk-pushing means (6) for pushing out the disks (8) one by one through the outlet (2). This prevents dust from entering or disks from popping out the magazine when the disk magazine (1) is not in use. A compact recording/reproducing apparatus provided detachably with the disk magazine (1) can be constructed if a single motor (85) is used to drive a pushing lever (87) for selectively thrusting the disk pushing means (6) to selectively push said disk (8) out of the disk magazine (1), and disk transfer means for loading the pushed disk (8) onto, or unloading it from, the recording/reproducing drive unit. A pushing lever (87) is connected to a press piece (107) which pushes portions (11a) of magazine slide levers (11) to be pushed, thereby causing discs to be pushed out of the magazine (1).
