Abstract:
1. A projection television apparatus comprising: a frame; a screen of a rear projection type attached to a front surface of the frame; and a projector unit, disposed in the frame, for emitting an image projection light beam onto the rear surface of the screen; wherein the projector unit comprises; wherein an optical axis of an optical path along which the image projection light beam travels is bent with respect to an optical axis of the projection lens; wherein a part extending from the image forming means to the projection lens is separated from a light source side unit which is a remaining part of the projector unit excluding the part extending from the image forming means to the projection lens, and the part extending from the image forming means to the projection lens is formed as an integrally coupled body into an image emergence side unit; wherein a support mechanism for supporting the image emergence side unit with respect to the frame rotatably around the optical axis of the projection lens along a plane orthogonal to the optical axis is provided; wherein an image adjusting mechanism by rotation for adjusting an angle of rotation around the optical axis of the projection lens, of the image emergence side unit is provided; and wherein a securing mechanism for loosening and tightening the image emergence side unit with respect to the frame is provided.
