Abstract

PURPOSE:To simplify the constitution of a control method for controlling a body to be controlled by adding and subtracting two controlled variables, prevent the occurrence of clattering and improve reliability by making use of a control cable consisting of an outer casing and an inner wire. CONSTITUTION:In the case of regulating exposure manually, the dial 7 of an operation part is rotated forward of backward, by which pulling force or pushing force is acted upon an inner wire 2, and along with this, a diaphragm ring 6 is rotated forward or backward, whereby arbitrary and delicate adjustment of exposure can be controlled. At the changing of copying magnification, a moving table 5 holding a lens barrel 3 is moved on a rail 4 by the magnification change-over operation signal and electricity is supplied to a motor 11, then the angle cam 12 corresponding to the changed copying magnification turns with respect to a cam follower 13, and required exposure correction is automatically controlled by way of the same control cable as that of the manual system.
