Abstract
1331784 Cine cameras AGFA GEVAERT A G 2 Oct 1970 [3 Oct 1969] 46960/70 Heading G2E A cine camera has a dissolve device comprising a rotary cam 2 driven by electric motor 19 when the device is switched on and the camera release is pressed, cam 2 operating firstly to close switch 21 in a circuit which progressively closes the diaphragm aperture 57 as film is loosely fed into a space in the cassette a spool, then, after 180 degrees rotation, to trip contacts 26, 27 to reverse motor 19 whereby the loose film is re-wound with the diaphragm closed, and finally, after a further 180 degrees, cam 2 opens switch 18 to stop the motor, the fade-in being provided after disconnection of the drive to cam 2 when film transport is switched on and switch 21 is opened to progressively open the diaphragm blades. The device is switched on by rotating knob 35 to lower slider 1 whereby pawl 3 locks takeup sprocket 38 against a friction clutch connection to motor-driven worm 37, and connected arm 4 depresses bell-crank 10 to engage gear 11 on eccentric 11a with worm 37. The eccentric reciprocates lever 14 carrying the spring-loaded pawl 15 which then rotates cam 2 by engaging teeth 2a. An inter-lock with slider 1 holds camera release 33 depressed so that the fade-out sequence cannot be halted. Fade-in may commence after rotation through 90 degrees of knob 35 to raise slider 1. In an alternative form, pawl 3 is selectively operable either as above with non-return cassettes to engage sprocket 38, or without engaging the sprocket of the cassette permits re-winding. The selective use of pawl 3 is controlled by a slider which senses the presence or absence of a groove on the cassette indicative of its type.
