Abstract
A device for providing a computer with electrically encoded data specifying curvilinear contours of an object comprises a manipulable frame member, componentry for establishing a reference position, a plurality of stylus elements, and means for measuring displacements of the stylii along respective axes. The componentry for establishing a reference position includes circuits for transmitting to the computer an electrical signal encoding a location of a reference point on the frame member. The stylus elements are each slidably mounted to the frame member for motion along respective axes extending at least partially parallel to one another. The means for measuring or detecting stylus displacements is operatively connected to the stylus elements for transmitting to the computer electrical signals encoding displacements of the stylii along the respective axes.
