  • Marking message card and template assembly and related input switching circuitry and method of making the assembly
    Patent number: 4178503
    Abstract: A novel optically readable message card having columns of marking areas thereon where the vertically adjacent marking areas in a column are horizontally staggered. Also, a template for the message card and having columns of horizontally staggered marking openings therein corresponding to the marking areas on the message card. The horizontal staggering arrangement assures that an unskilled user will make a sufficiently long mark in the marking area on the message card so that the mark can be read by commercially available optical mark reading equipment. Furthermore, the staggered openings in the template assure the structural strength of the template. Also, a structurally strong, easy-to-use template assembly including the template and a base plate designed to hold the message card and accurately align it with the template. Also, a method of economically mass-producing the template assemblies.
    Type: Grant

  • Marking document and template assembly and method of making the assembly
    Patent number: 4001549
    Abstract: An optically scannable document having columns of marking areas thereon where the vertically adjacent marking areas in a column are horizontally staggered. Also, a template for the document and having columns of horizontally staggered marking openings therein corresponding to the marking areas on the document. The horizontal staggering arrangement assures that an unskilled user will make a sufficiently long mark in the marking area on the document so that the mark can be scanned by commercially available optical scanning equipment. Furthermore, the staggered openings in the template assure the structural strength of the template. Also, a template assembly including the template and a base plate designed to hold the document and accurately align it with the template. Also, a method of mass-producing the template assemblies.
