ABSTRACT:
The apparatus of the invention comprises a conventional photocopy machine having a stationary light receiving device and a moving copyboard in combination with a light fixture attachment. The light fixture comprises an elongated lamp and a support for holding the lamp above the copier and aligned with the stationary image receiving device. The support comprises a base which is positioned under the copier, a vertical leg attached to the base, and a horizontal arm pivotally connected to the vertical leg. The lamp is secured to the horizontal arm. The pivotal connection of the horizontal arm to the vertical leg permits the lamp to be pivoted to and from a position above the copyboard. The lamp when pivoted over the copyboard is aligned with the light receiving device of the copier. Thus, when a radiograph is placed on the copyboard, light emitted from the lamp passes through the radiograph and copyboard and is received by the image receiving device of the copier. The additional light from the lamp of the invention, directed through the radiograph, greatly enhances the quality of xerographic reproduction of the radiograph.
