Abstract
1404251 Cinematography MEOPTA NARODNI PODNIK 27 April 1973 [27 April 1972] 20063/73 Heading G2E A cine projector for projecting films of different dimensions (e.g. standard and super 8) is able to project a single frame for prolonged periods. It includes a base-plate 4 carrying a lens 48 and a lamp holder 46, the base-plate 4 having a bent portion 40 carrying a film guide 5 and a positioning member 6 on opposite sides thereof. A film feed claw arm 2, deriving motion from cams 251, 252 through pin 221, is coaxially pivotally mounted with member 6 on pin 23. When pivoted the member 6 contacts pin 221 and holds the claw 211 clear of the film F. The film guide 5 includes a base portion 51, a pressure plate (55), Fig. 8 (not shown) and a masking plate 52 having apertures 524, 525 (one for each film type). The plate 52 is moved by handle 521 and attached pins 522 are guided by diagonal slots in member 6 so that the correct position of the frame relative to the perforations is ensured. The pivoting of member 6 permits the film guide to be removed. Bracket 67 on member 6 moves a heat filter across the optical axis when the claw 211 is disengaged.
