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.
Claims19
A projector comprising:
- an image forming panel for displaying images;
- a light source that illuminates the image forming panel;
- a housing that houses the image forming panel and the light source, and includes a storage section formed by cutting a part of the housing, a first surface, a second surface intersecting the first surface, and a third surface facing the second surface;
- and
- a projection lens disposed in the storage section and attached to the first surface, the projection lens including a first holding member through which light with a first optical axis passes, a first reflective member which bends the first optical axis to form a second optical axis, and a second holding member through which the light with the second optical axis passes,
- wherein the projection lens is rotatable around the first optical axis between a first position where the second holding member faces along the long side direction of the first surface and a second position where the second holding member protrudes from the second surface in a side view, and
- wherein the projection lens faces the third surface.
