Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
92 words
A mechanism for marking a bar code on a document comprising: A. an apertured surface, B. means for pressing one side of said document against said apertured surface to hold it stationary with respect to said apertured surface, C. stylus means for marking the other side of said document through the aperture, and D. means to move said stylus means towards and into contact with the other side of said document and subsequently along the surface of said other side of said document while in contact therewith to mark a bar thereon.
Claim 2
Dependent Claim
92 words
A mechanism for marking a bar code on a document comprising: A. an apertured surface, B. means for pressing one side of said document against said apertured surface to hold it stationary with respect to said apertured surface, C. stylus means for marking the other side of said document through the aperture, and D. means to move said stylus means towards and into contact with the other side of said document and subsequently along the surface of said other side of said document while in contact therewith to mark a bar thereon.
