Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
A copy holder comprising a stand having a support surface, a metal edge extending along at least one side of the support surface, a line guide extending across the support surface, a line guide housing disposed along an end portion of the line guide and in movable registration with the metal edge of the support surface, said housing including at least a pair of magnetic rollers rotatably mounted within the housing, each roller including a magnet having a North pole and a South pole and means for magnetically and rotatably contacting each magnetic pole with the metal edge, said means disposed adjacent said poles, the magnets of each roller are toroid shaped, the means for magnetically and rotatably contacting the North and South pole of each magnet with the metal edge comprises metallic, concentric end pieces rotatably engaged with the magnets at their poles, the diameter of the end pieces is greater than the diameter of the magnets and the magnetic rollers are biased in rotatable alignment against an inner wall of the housing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
124 words
A line guide for use with a copy holder comprising a housing, a ruler, means for securing one end of the ruler to the housing, and at least a pair of magnetic rollers each having a North pole and a South pole, rotatably mounted within the housing, each roller including a toroid shaped magnet rotatably mounted side-by-side said magnets having outer, rolling, surfaces aligned relatively perpendicular to the ruler for rolling magnetic contact with an edge of the copy holder, each magnet is concentrically disposed at its North and South poles and rotatably engaged between metallic pieces having a diameter slightly greater than that of each magnet and biasing means for resiliently mounting each magnet in rotatable alignment against a wall of the housing.
