Abstract:
1. A projection type image display apparatus comprising a light source, an optical component that modulates light from the light source and projects an image signal, a circuit board that has via holes and on which a plurality of external connectors are mounted, and a cabinet that houses the aforementioned elements; the projection type image display apparatus further comprising a single connector cover provided to cover the plurality of external connectors so that a tip end part of each of the external connectors is exposed respectively to the outside, and a single dustproof cover provided for the external connectors opposing the connector cover, the dustproof cover having a base member from which a solid peripheral wall extends, the base member having a peripheral portion where the peripheral wall is not present that defines a first edge, the peripheral wall defining a second edge in a plane that is spaced from the base member and third and fourth edges that extend between the first edge and the second edge, the second edge engaging the circuit board, and the first, third and fourth edges engaging the connector cover to define a closed space enclosing the plurality of external connectors, whereby dust and dirt entered from a clearance between the tip end part of each of the external connectors and the connector cover are prevented from further entering into an area of the optical component by the presence of the closed space.
