Abstract: A projection type image display device to be used with a mobile terminal has a housing with an upper side case having a reflective mirror attached thereto and an openable mirror cover formed thereon and a lower side case having a plurality of air exhausting openings provided on a side wall surface thereof. A light source is provided for shining image light that has been magnified and projected onto the reflective mirror; and an image is magnified and projected on the basis of the light from the light source. An optical system is disposed within the lower side case parallel to the bottom surface of the case along a central axis of the device, and also an image processing unit, which includes the light source, and a power supply unit are disposed within the lower case symmetrically with the optical system as the center.

Abstract: Without increasing the size of a projection video display device that has a mirror that can be raised and lowered, this invention makes it easy to raise and lower said mirror. In order to do so, this projection video display device, which enlarges and projects an image from an image-displaying means, has a housing (10) and a raisable/lowerable mirror (30) wherein: a power supply, a light source, and a lens unit are accommodated inside the housing (10); said lens unit enlarges light from the light source after said light has been directed to the aforementioned image-displaying means; and the raisable/lowerable mirror (30) covers a projection-light opening (26) formed in the top surface of the housing (10), is provided so as to be able to rotate with respect to the housing (10), and has a convex mirror (110) on the inside surface thereof. With the raisable/lowerable mirror (30) covering the top surface of the housing (10), the top surface of the projection video display device forms a smoothly connected, smooth, convexly curved surface with no height difference between the edge of the raisable/lowerable mirror (30) and the front edge of the opening (26), and a half-bowl-shaped concavity (45) is formed on at least one side of the raisable/lowerable mirror (30) in the direction of the axis of rotation thereof.
