ABSTRACT:
A structure of a projector engine section includes: an engine section that projects through a projector lens an optical image formed by modulating a light flux depending on image information; a circuit board that has a digital mirror device control circuit and attached to the engine section; a heat sink that faces the circuit board so as to prevent a heat generation due to the fullness of heat in the engine section; and a gasket plate that is made of a sheet metal and is inserted into the space between the circuit board and the heat sink, such that the gasket plate elastically contacts with a ground pattern of the circuit board and the heat sink.
