ABSTRACT:
An apparatus is provided which maintains alignment of panels in a projector. The apparatus includes a synthesizing system holding device positioned at an upper portion of a synthesizing system of the projector which securely supports the synthesizing system and maintains a relative position of various components of the synthesizing system, even in the event of an external force or vibration applied to the projector. This apparatus can prevent deviation or misalignment between at least two or more prisms and panels in the synthesizing system of the projector, thereby improving reliability and durability of the projector and enhancing image quality.
