    • A projection apparatus includes an optical engine (10) that projects an image on a screen from a rear side, an engine supporting plate (100) on which the optical engine (10) is placed, an adjusting member (500) of a substantially wedge-shape inserted into between a base portion (11) and a lower surface of the engine supporting plate (100) so that front or rear end of the engine supporting plate (100) is vertically rotatable, a front-to-rear position adjusting unit (56) capable of moving the adjusting member (500) in front-to-rear direction, a slope portion (108) having a slope surface (109) that gradually increases or decreases an angle of a surface of the adjusting member (500) contacting the engine supporting plate (100) in accordance with a movement of the adjusting member (500), and a fixing unit (551, 552) that fixes the engine supporting plate (100) to an adjusted position.
    • 投影装置包括从后侧将图像投影在屏幕上的光学引擎(10),放置有光学引擎(10)的发动机支撑板(100),大致楔形的调节构件(500) 插入到基部(11)和发动机支撑板(100)的下表面之间,使得发动机支撑板(100)的前端或后端可竖直旋转,前后位置调节单元 能够沿前后方向移动调节构件(500)的倾斜部(56),具有逐渐增大或减小调节构件(500)的表面的角度的倾斜面(109)的倾斜部(108) 根据调节构件(500)的移动使发动机支撑板(100)接触,以及将发动机支撑板(100)固定到调整位置的固定单元(551,552)。
