<p>905,978. Photographic cameras. PAILLARD S. A. May 12, 1959 [June 11, 1958], No. 16204/59. Class 98 (1). A camera has a photo-electric cell adapted to be moved into the light beam behind the objective and means which are operated by the shutter release device to allow the cell to be retracted by elastic means during photographing, a locking lever for the cell in its operative position being controlled by the shutter release device. A photo-electric cell 1 mounted on an arm 2, pivoted at 3, is movable over the objective aperture 8. Normally it is held away from aperture 8 by a spring 6 but when knob 9 is depressed (as shown) it is rotated until projection 18 is caught by a notch 17 in a lever 12. The lever 12 is controlled at one end 13 by a plate 14 attached via staple 19 to the shutter release device. When staple 19 is moved down to release the shutter lever 12 is rotated about a pivot 15 and arm 2 is released and is moved by spring 6 to the left. Movement of plate 14 releases the shutter control member 23. If, instead of opening the shutter, knob 9 is depressed further projection 18 moves over surface 25 and rotates lever 12 about point 13 until spring 27 catches on shoulder 28 and arm 2 is released and moves to the left, whereby moving spring 27 to the left and releasing lever 12. The sizes of noses 17, 18, 21 may be designed so that on depressing the shutter release mechanism arm 2 is released before member 23.</p> |
