Claims

[Scope of utility model registration request]

(1) A viewing window for observing an object by projecting a real image of the object on the opposite side of the opaque material onto a screen using a positive lens system embedded in an opaque material that does not transmit light; A viewing window characterized in that convex lenses are closely juxtaposed on the screen, and a reflective optical system that inverts the entire structure at least vertically is placed adjacent to the screen.

(2) The viewing window according to claim (1), wherein the screen and the convex lens are located between the reflection/inversion optical system and the lens system.
゛

(3) The viewing window according to claim (1), wherein the screen and the convex lens are located inside the catoptric optical system.

(4) The viewing window according to claim 2 or 9, wherein the convex lens is a plano-convex lens, with its flat side facing the screen.

(5) The viewing window according to any one of claims (1) to (4) of the utility model registration claim, wherein the reflective optical system is inverted vertically and horizontally. .
