Abstract

1,235,192. Picture viewing apparatus. P.R. JOHNSON, K.W. MELCHIOR, P. L. HANSON. [trading as OPTICAL DEVICES CO; ] May 13, 1968 [May 12, 1967], No. 22649/68. Headings G2C and G2E. In a motion or still picture display apparatus, an array of picture frame areas and a corresponding array of lenses, one for each frame, are continuously moved relative to an objective lens with a continuously open aperture such that the lenses and frames move together in succession past the objective lens. A viewing device comprises a spiral lens matrix 20 against which is separably mounted a similar picture disc 54, located by pin 56, the disc and matrix being rotated, by means of a hand-crank 48 and belt drive 28, on a shaft 42. A pin 50 in casing 12 engages a spiral groove in the matrix to cam the rotating unit through an arc which allows successive frames to be viewed through aperture 60 in eye-piece 58, shaft 42 moving in slot 36 for this purpose. Disc 54 is at the focal distance from lens matrix 20 so that parallel light enters lens 24 adjacent aperture 60 and is imaged for direct viewing, or projection on to a screen. A modification of this form includes a hand-driven sprocket engages perforations in the matrix. The picture matrix may be embossed on the rear surface of the lens matrix.
