Abstract: A projection display device includes a light source; an optical system which modulates light from the light source, and emits the modulated light; a projecting portion which enlarges and projects the light emitted from the optical system; a cabinet which houses the light source, the optical system, and the projecting portion; an opening which is formed in one surface of the cabinet to allow mounting or dismounting of an optical component constituting the optical system, or the light source; a cover which covers the opening; and a holding portion which holds the cover in such a manner that the cover is allowed to slide in a direction along the one surface.

Abstract: A projection display device accommodates, in a main body cabinet, a projection lens section to which light modulated by a light modulating element is entered, and a mirror section that reflects light transmitted through the projection lens section and directs the light to a projection plane. When the main body cabinet is mounted on a mounting plane so that the light transmitted through the projection lens section may get away from the mounting plane, a holding member which holds the main body cabinet in a upright state with regard to the mounting plane is mounted on the main body cabinet.

Abstract: A projection display device is provided with an adjustable leg which adjusts an inclination of the main body cabinet. The adjustable leg includes a leg portion whose projection amount from the bottom surface is changed, and a foot portion which is contacted with an installation plane of the projection display device, the adjustable leg being expandable and contractible from a reference length position at which the main body cabinet is placed in parallel to the installation plane. The bottom surface of the main body cabinet has a recess portion which is configured so as to guide in and out of the foot portion, as the adjustable leg is contracted and expanded. The foot portion has an index portion which is set to the same height as the height of the bottom surface with respect to the installation plane, when the adjustable leg is positioned at the reference length position.

Abstract: A projection image display apparatus includes: a first casing which includes an image projection unit provided therein and a projection window provided at one end side thereof; and a second casing which has one end side coupled with the other end side of the first casing pivotably around a pivot axis. The first casing and the second casing are switchable between a first condition in which one side surface of the first casing and one side surface of the second casing are aligned opposite to each other and a second condition in which the first casing is pivoted from the first condition around the pivot axis within a plane orthogonal to the pivot axis and thus erected relative to the second casing.

Abstract: A projection display apparatus (100) has an image light generating unit (200), a projection optical unit (300) and a screen (220). The projection optical unit (300) has a reflection mirror (320). The screen (220) is switchably configured to as to switch to whether to diffuse image light reflected by the reflection mirror (320) or to transmit the image light reflected by the reflection mirror (320).

Abstract: A projection display apparatus (100) includes a image light generation unit (200) and a projection optical unit (300). The projection optical unit (300) has a reflecting mirror (320). The projection optical unit (300) is configured to project image light in a plurality of directions without changing the disposition of the projection display apparatus (100).

Abstract: A projection display device comprises a main body cabinet, a projection lens section to which light modulated by a light modulating element entered, and a mirror section for reflecting the light emitted from the projection lens section to a projection plane. A level difference depending on an arrangement shift of the projection lens section and the mirror section is formed on a second side surface facing a first side surface having light projection port of the main body cabinet. Furthermore, the projection display device comprises a level difference correction section for directing the light from the mirror section in a desired direction by correcting the level difference, when the main body cabinet is planed on a plane to be placed, the second side surface facing the plane to be placed.
