Abstract

PURPOSE:To adjust a lens and a mirror by a motor which rotates in one direction by extending a wire for moving the lens to the roll of an arm member, and coupling the shaft of the arm member with a cam shaft for adjusting the position of the 2nd mirror. CONSTITUTION:The wires 10 and 11 for moving a pedestal 1 mounting a lens 2 are fixed locking metallic fixtures 12 and 13, and are extended to the roll 17 of an arm member 19 at the other ends. The shaft of the arm member 19 is coupled with the shaft of a cam 22 for adjusting the position of the 2nd mirror, and a roll 24 abuts on the cam 22. For magnification variation, when the arm member 19 is rotated as shown by an arrow 39 until an alternate long and two short dashes line, the lens 2 is drawn to left by the wire 10 and is stopped at a prescribed position by a stopper 36. At the same time, the cam 22 also rotates as shown by the arrow 39 and the 2nd mirror moves to right until the attitude of the magnification variation is obtained. Thus, the positions of the lens and mirror are adjusted by the rotation of the one directional motor.
