Optical imaging apparatus
First Claim
1. An image projecting apparatus adapted to display an image of an object whereby an observer can see the image, comprising:
- (a) a housing defining an enclosure and having an interior and an object support area adapted to receive an object to be displayed, said housing including a front portion having a view region viewable by an observer located exteriorly of said housing;
(b) a concave first reflective surface disposed in said housing and oriented to receive light from the object and operative to produce a virtual image of the object when the object is placed on the object support area;
(c) a second reflective surface disposed in said housing and oriented to reflect the virtual image produced by the first reflective surface as a real image of the object, said second reflective surface operative to project the real image into the view region; and
(d) a masking member disposed in said housing and interposed between the object support area and the view region such that the object cannot be viewed directly through the view region by said observer.

Abstract
An image projecting apparatus is provided to project a real image of an object to be displayed while obscuring the object from view by an observer located exteriorly of the image projecting apparatus. The apparatus includes a housing (12) having an interior and a view area (14) for the real image. First and second reflective surfaces (40, 50), such as mirrors, are disposed in the housing. The first reflective surf (40) must be concave of a variety of geometric shapes. The second reflective surface (50) may be concave or, alternatively, planar. A masking member is interposed between the object and the view area. The second reflective surface can define the masking member. The first and second reflective surfaces are arranged at an acute angle to each other.

10. An image projecting apparatus adapted to be supported on a support surface and operative to a support to display an image of an object whereby an observer can see the image, comprising:
-
(a) a housing defining an enclosure and having an interior and an object support area adapted to receive an object to be displayed, said housing including a front portion having a view region viewable by an observer located exteriorly of said housing;
(b) a concave first mirror disposed in said housing and having a first peripheral edge, a first median plane containing the first peripheral edge and a center, said first mirror oriented to receive light from the object and operative to produce a virtual image of the object when the object is placed on the object support area;
(c) a second mirror disposed in said housing and having a second peripheral edge, a second median plane containing the second peripheral edge and a center, said second mirror oriented to reflect the virtual image produced by the first reflective surface as a real image of the object, said second reflective surface operative to project the real image into the view region, said housing configured to support said first mirror such that the first median plane is oriented at an angle of 25°
to 80°
with respect to a horizontal plane passing through said housing and to support said second mirror such that the second median plane is oriented at an angle of 0°
to 20°
with respect to the horizontal plane; and
(d) a masking member disposed in said housing and interposed between the object support area and the view region such that the object cannot be viewed directly through the view region by said observer. - View Dependent Claims (11, 12, 13)
