ABSTRACT:
A light transmission device for transmitting light from a stationary light source to a movable recording element of an electronic reproduction device composed of at least one fiber optical light waveguide and one guide element for the fiber optical waveguide. Due to the motion of a fiber optical waveguide, inhomogeneous light distributions arise at its exit face, this leading to disturbing streaked exposures of the recording medium. In the present invention to avoid such streak-like exposures, it is proposed that the guide element be a metal band which is mounted in a U-shape with the fiber optical waveguide being connected to one side of the metal band. Thus, as the recording element shifts, the curvature of the fiber optical waveguide remains constant to prevent shifting of the light distribution exiting the fiber optical waveguide.
