Electronic scaler

An electronic copyscaler comprising:

• a first framing arm including two adjacent straight cursor means which are substantially perpendicular,
• a second framing arm including two adjacent straight cursor means which are substantially perpendicular,
• means adjustably connecting said first and second arms together in overlapping arrangement to enclose a rectangular area of adjustable size bordered by said cursor means, said arms being movable relative to each other along orthogonal directions parallel to said cursor means,
• detector means associated with said arms for detecting the degree of relative displacement between said arms along each of said orthogonal directions and providing an output signal quantatively corresponding to said degree of displacement, and
• electronic calculator means connected to said detector means and having an input connected to said output signal, a display and a manually operated data entry means,
• said calculator means being responsive to said output signal for storing first position data corresponding to an initial relative position of said arms and copy data inputted by said data entry means and computing character data representative of the amount of copy enclosed by said arms when in their initial relative position,
• said calculator means being responsive to said output signal for storing second position data corresponding to a second relative position of said arms and layout data inputted by said data entry means and computing and displaying layout area data representative of the layout area fit, related to said enclosed copy, enclosed by said arms when in the second relative position.
