Abstract: A projector includes a projection lens and a projector body. In the projection lens, a U-shaped optical path is formed by optical axis to optical axis. A lens barrel is a U-shaped barrel. A housing of the projector body includes a storage section. The projection lens is supported rotatably about the optical axis with respect to the housing, in an up-down direction and a right-left direction of the housing perpendicular to the optical axis, between a first position where the projection lens is stored inside a storage section provided in the housing and a second position where the projection lens is protruding from the housing.

Abstract: A projection-type display device includes: R, G, and B light sources that emit light beams with different colors; a projection unit that projects light beams based on image information among light beams emitted from the light sources onto a projection screen; a heat sink that radiates heat generated from the R light source, which has a maximum change in light emission intensity relative to a change in temperature, among the light sources; and a heat sink that radiates heat generated from the G and B light sources and that has a surface area smaller than that of the heat sink. In a use state, the R light source is disposed on a side apart from the other light sources in a direction opposite to a direction of gravitational force.

Abstract: A first holding barrel, a first mirror bending a first optical axis of the first holding barrel at 90°, a second holding barrel, a second mirror bending a second optical axis of the second holding barrel at 90°, and a third holding barrel are disposed on an optical axis from a screen side to an image forming panel. A first connection member connects the first holding barrel including the first mirror to the second holding barrel to be rotationally movable in increments of 90°. A second connection member connects the second holding barrel and the second mirror to the third holding barrel to be rotationally movable in increments of 90°. An orientation of a display image of the image forming panel is changed based on rotational movement states of an optical axis of a first sensor and an optical axis of a second sensor to make an orientation of a projection image on the screen match an original image.

Abstract: A first optical system, a first mirror, a second optical system, a second mirror, and a third optical system are disposed in order on an optical axis from an image forming panel to a screen. A first optical axis of the first optical system, a second optical axis of the second optical system, and a third optical axis of the third optical system are formed in a U shape, and orientations of luminous fluxes of the first optical axis and the third optical axis are reversed. The first mirror, the second optical system, the second mirror, and the third optical system are held to make a second holding barrel with respect to the first optical system. The second holding barrel is rotationally moved in a rotational movement range of 45° with respect to a first holding barrel. In projecting portrait image instead of a landscape image, the second holding barrel is rotated in increments of 45° with respect to the first holding barrel.
