Abstract
1,175,454. Optical viewing or projecting apparatus. ITEK CORP. Jan. 3, 1967 [Jan.3, 1966], No.346/67. Heading G2J. An optical viewer or projector has a support mechanism adjacent the film gate for supporting a transparency, said mechanism including a support member and a transparency positioning means for selectively moving the support member along its length and orthogonally thereto but perpendicular to the optical axis. As shown in Fig. 1, the transparency 6 rides on belt 1, passing over pulleys 2, 3 and around a reinforcing member 4. The transparency is moved horizontally by turning knob 9, which acts through gears 11, 12 to move the belt 6 about the pulleys 3, and vertically by turning the knob 14 which acts through pulleys 25, 28, 29 to lift or lower the reinforcing member 4. The transparency is also supported between optical flats Fig. 4 (not shown) one of which is fixed and the other which pivots under the action of a solenoid to allow the transparency to move. The solenoid is actuated by turning the knobs 9 or 14 which activates switch 58 or 59. If a strip of film is used turning of the spools carrying it activates similar switches.
