Title: Improvements in or relating to photographic cameras
IPC: G03B7/083
Filed: 1966-10-19
Abstract: 1,142,994. Photographic camera. PRONTORWERK ALFRED GAUTHIER, G.m.b.H. Oct. 19, 1966 [Oct. 23, 1965], No.46736/66. Heading G2A. An automatic camera comprises a moving-coil galvanometer 5 having a needle 4 deflected in accordance with the illumination of a photo-cell (20), means for sensing the position of the needle on actuation of the shutter release which set the lens aperture of the camera by a diaphragm 12 in accordance with the position of the needle, a shutter 24 controlled by an electronic timing circuit containing the photo-cell (20), and a further device for altering the timing in accordance with the selected aperture. On depression of camera release 2, needle 4 is immediately clamped against further movement by a pivoted bar 8 and a spring biased sensing member 6 attached to the setting ring 13 of diaphragm 12 moves downwards until its surface 6d engages and is halted by needle 4, the total movement of member 6, and hence the aperture set by ring 13, being dependant on the position of needle 4 and the shape of surface 6d. Further movement of shutter release 2 closes a switch S2, which energizes an electromagnet (M) in the timing circuit, and trips a lever 29 to release a shutter driver 26, so that shutter 24 is opened, but is prevented from closing by electromagnet (M) which has an armature 42. Simultaneously with the opening of shutter 24, the state of two switches S3, S4 in the circuit is changed by shutter drive 26 to initiate the charging of a capacitor (C) by a battery (33); when charging is complete, the state of a pair of transistors (T1), (T2) is changed so that electromagnet (M) is de-energized allowing shutter 24 to close. The time taken for charging and hence the exposure time is determined by the resistance, and hence the illumination of photo-cell (20) during charging; this, in turn, is determined by the ambient light, by a grey-wedge 46 set in accordance with the film-speed, and by a diaphragm 18 which is positioned in front of the cell and is set by and in accordance with, diaphragm 12. Needle 4 moves over a visible scale (50) to indicate when exposures are possible and what aperture and time the camera will set. A switch S1 is provided in the electronic circuit which shorts out photo-cell (20) so that the deflection of needle 4 is controlled only by battery (33) and thus tests the state of the latter; if desired a second battery (55) may be provided in the circuit for this test. In alternative embodiments, a grey-wedge in front of photo-cell (20) or a variable resistance (R1) in the electronic circuit, is set in accordance with the lens aperture, and a photo-cell diaphragm in front of photo-cell (20) is set in accordance with the film sensitivity; the shape of surface 6d may be altered to provide a different lens aperture/exposure time programme.
