Abstract

PURPOSE: To enable an imaging optical system to be moved to specified positions and its positioning to be performed by providing an optical axis correcting means maintaining the optical axis direction of the imaging optical system always constant in cooperation with the turning of the oscillating arm pivotally supporting the imaging optical system.
CONSTITUTION: An imaging optical system 3 is pivotally fitted to one end 2 of an oscillating arm 1 of U-form in section and the other end 4 fits to a circular oscillating shaft 5 of a partly notched section and is able to move in the Z-axis direction. The entire part thereof is so constituted as to be slidable in the X-axis direction as well. When the oscillating shaft 5 turns by an angle θ in the clockwise direction, the oscillating arm 1 is also turend clockwise by the angle θ with the through-part of the oscillating shaft 5 as a fulcrum. Since at this time a pulley 20 is stopped by a stopping arm 23, the pulley 20 rotates counterclockwise relatively by the angle with respect to the turning of the oscillating arm 1 and this rotating motion is transmitted via wire 21 to a pulley 19, by which the imaging optical system 3 is rotated by the angle θ counterclockwise with respect to the oscillating arm 1.
