ABSTRACT:
A cursor assembly for use in association with a viewing window of a microfiche viewer consisting of a first guide rail, a slide member and a reader bar projecting outwardly from the slide member. The slide member has U-shaped slipway extending longitudinally thereof. The slipway is substantially wider than the guide rail whereby the slide member may be located on the guide rail with the guide rail extending longitudinally through the slipway. A permanent magnet is carried by the slide member such that the slipway is located within the magnetic field of the magnet whereby the slide member may be magnetically secured with respect to the guide rail. The reader bar projects outwardly from the slide member and extends across the viewing window in use. The slipway and guide rail are proportioned to permit the slipway to be angularly inclined with respect to the guide rail to be angularly adjustable with respect to the guide rail to be aligned with images readable on the viewing window.
