Abstract

A pinhole type camera is in the shape of a polyhedron and is formed from a cut and scored blank of paperboard. It is provided with a separate structure formed from a second cut and scored blank and disposed within the hollow polyhedron, the separate structure constraining photo-sensitive material along side edges thereof into position.

Claims

1. A camera in the form of a hollow polyhedron having structure therein for holding photo-sensitive sheet material in position by constraining the sheet along opposite sides thereof, said camera and said structure being formed from a pair of cut and scored blanks of paperboard or the like and comprising:

(a) a first blank having foldably connected rectangular front, trapezoidal-shaped top and bottom and rectangular rear panels;

(b) side panels foldably connected to said panels and foldable into erected position to define a structure of polyhedron shape;

(c) certain of the side panels being foldable with respect to said trapezoidal-shaped top panel and providing a cover extending over the side panels extending from said trapezoid-shaped bottom panel and said front rectangular panel;

(d) a second blank for forming a structure constraining said film material in position close to said rear panel and having a main panel with opposed side and opposed upper and lower flange elements extending from said main panel and foldably connected thereto;

(e) said upper and lower flange elements having curved edges against which photo-sensitive film material is constrained; and

(f) an aperture in said front panel for transmitting light therethrough against said photo-sensitive material when in position close to said main panel.

2. A camera according to claim 1, wherein said second blank provides tabs constraining said film material along the side thereof.

3. A camera according to claim 1, wherein said front panel is provided with a mask swivelable between opening and closing positions with respect to said aperture.
