ABSTRACT:
An improvement in a digitizer for use in computer drafting has been provided wherein a multiple wire connector located in both the X beam and Y beam is held in a taut and concealed condition within the respective beams for any position of the digitizer. An adjustable attachment is provided between the extrusions for the X and Y beam and the respective X and Y guide bars so that the guide bar can be aligned in a straight condition regardless of any warping of the beams during extrusion. A mechanical brake is also provided for fixing the position of the digitizer during use.
