Abstract:
A proximity projection-type projector includes a housing; a dust-proof cover arranged on a top portion of the housing; and a projection unit arranged within the housing. The projection unit projects projection light though the dust-proof cover on the housing toward a screen disposed outside the housing. An anti-reflection film forms a light incident surface of the dust-proof cover.
