Cursor assembly

A cursor assembly for use on a viewing window of a microfiche reader or the like comprising:

• (a) a guide rail consisting of a longitudinally elongated ferrous member having a front face, a back face and a pair of oppositely disposed side faces,
• (b) resilient adhesive means on said back face of said guide rail for adhesively securing said rail to a window of a reader or the like,
• (c) a slide member having an inner face, a recess formed in said inner face,
• (d) a U-shaped ferrous insert mounted in said recess of said slide member and opening outwardly therefrom, said U-shaped ferrous insert having a pair of oppositely disposed side walls having their outer edges disposed adjacent said inner face of said slide member and extending longitudinally of said recess,
• (e) a permanent magnet mounted in said U-shaped ferrous insert, said permanent magnet having an outer face spaced inwardly from said outer edges of said insert and cooperating with said side walls of said insert to form a U-shaped slipway extending longitudinally of said slide member,
• (f) low friction plastic liner means on said outer face of said insert and on the portions of said side walls of said insert which are located in said U-shaped slipway,
• (g) said U-shaped slipway being disposed within the magnetic field of said magnet and said side walls of said ferrous insert being magnetized whereby said slide member may be magnetically secured with respect to said guide rail at said inner face of said U-shaped channel and at each side wall of said U-shaped channel when said guide rail is located within said slipway,
• (h) a reader bar projecting outwardly from said slide member substantially normal to said slipway,
• (i) said slipway being substantially wider than said guide rail whereby said slipway and thus said reader bar may be angularly inclined with respect to said guide rail or may extend normal to said guide rail to be aligned with images readable on said window.
