Abstract
An adjusting mechanism for a rod module adapted to an optical engine is provided. The adjusting mechanism utilizes two wedge-shaped blocks moving in perpendicular directions so as to convert the vertical adjustment of horizontal adjusting component into horizontal adjustment of an LIR module. Therefore, operators may adjust the horizontal and vertical position of the rod module from the same side of the projector, thus increasing the convenience in adjusting the position of the rod module.
