Class 97(1) An intermittent feed projector includes a plurality of discharge lamps and a condenser system which is moved rapidly relatively to the film gate each lamp being lit when in optimum relationship with its associated condenser and the gate. Thus, as shown, successive parts of each film frame 6 are illuminated by lamps 1, illuminated in sequence, in association with one of a series of condenser lenses 3 mounted in a rotating disc 2, for projection by the objective 7. This arrangement is advantageous where the film frame has a large width : height ratio. |
