An adjustment apparatus comprises a base seat, sliding bracket and supporting stand, in which the lower surface of sliding bracket is contacted with the upper surface of the base seat and capable of being slid thereon. A mounting plate is installed at the upper end of the sliding bracket and a raised pin is projected on the surface of the mounting plate. The raised pin can be engaged with a rotating plate. A lens of an optical engine fixed and mounted on the surface of the rotating plate can be rotated levelly around the raised pin to do an adjustment to revise the rightward and leftward trapezoid deformation of an image projected on a screen. Besides, every kind of deformation can be revised by means of the multi-angles adjustment of a reflection mirror on the supporting stand installed at the front end of the sliding bracket.
