Abstract

PURPOSE:To simplify the drive apparatus, by moving the first and second moving bodies on two paths parallel to each other in the directions reverse from each other like one body. CONSTITUTION:First moving body 7 containing an optical system immodilized in the direction other than the horizontal one, and second moving body 8 having an almost same mass as body 7 are arranged so that these two bodies 7, 8 can move on two paths parallel to each other in the direction reverse from each other like in one body. In other words, bodies 7, 8 are formed into a closed loop with wires 11, 11, which are supported with pulleys 9, 10 driven with a motor, etc.
