ABSTRACT:
A device for moving a curved plate bent in a substantially arcuate-shape, in which a lift arm driven by a rotary shaft and carrying the curved plate at one end thereof to cause movement of the curved plate is pivotably supported on a pivot mounted on a base, and the axis of this pivot is directed to make an acute angle with the moving plane of the curved plate. In the device, the curved plate carrying end of the lift arm moves along a curved path the curvature of which is substantially equal to that of the curved plate, thereby preventing impartation of a stress tending to cause deformation of the device.
