Abstract

PURPOSE: To automatically control aperture quantity with simple and small-size constitution by magnetizing the electromagnet according to the brightness of the subject thereby adjusting the operation quantity of an aperture lever.
CONSTITUTION: The magnetization intensity and magnetizing direction of an electromagnet 18 change in correspondence to the brightness of the subject, whereby the turning of a detaining lever 15 is controlled. Cooperatively with the lever 15, an aperture lever 13 turns and the aperture quantity by a lever 14 is controlled by way of the protrusion part 13c of the lver 15. This constitution which does not require any sliding member and the like makes the automatic aperture control part simple and small in size.
