Abstract: PURPOSE: A projector and a display device with the same are provided to minimize the length of a projecting window of the projector even though the projecting window is arranged in the center and to improve the thermal stability of the projector. CONSTITUTION: A projector comprises an optical system, a light source heat radiation unit, circuit boards(120,130), an inhalation unit, an exhaust unit, and a path dividing unit(340). The optical system forms images, magnify-projects the images, and includes at least one light source. The light source heat radiation unit radiates heats of the light source. The circuit boards operate the projector. The inhalation unit includes an air inlet. The exhaust unit includes an air outlet. The path dividing unit divides a cooling path formed between the air inlet and air outlet into upper and lower cooling paths.

Abstract: PURPOSE: A focus controlling device and a projector applying the same is provided to overcome an asymmetric of focus controlling amount by optical characteristic. CONSTITUTION: A focus controlling device comprises a focus control unit(40) and an operating unit(50). The focus control unit is installed at a projecting lens unit to control the focus by rotating lens barrel of a projection lens unit. The operating unit is gear meshed to the focus control unit to provide rotation strength on the focus control unit by installing on the main body of the projector to rectilinear. The focus control unit and the operating unit vary the rotation quantity of the focus control unit to the constant rate liner movement of the operating unit.

Abstract: An image projection device is provided to distribute influence of environment and temperature on the projection optics evenly so as to prevent the optical performance difference between elements of the projection optics. An image projection device comprises a cabinet(30), a screen(41) formed in the cabinet, a display element(50) which is arranged inside the cabinet to form an image, one or more mirrors(M) projecting the formed image onto a screen, a support member(65) holding the mirrors, and a frame(67) fixing the support member to the cabinet. The mirrors, the support member and the frame are arranged in the same internal space formed by the cabinet and the screen.
