Graphics tablet menu locator accommodating differing sizes of paper

摘要

A digitizer platen or tablet incorporates a recess within its surface. The recess has plural multiples of four interior corners for interlocking with predetermined sizes of rectangular paper wherein no two lengths are equal and no two widths are equal. Menus are plotted or otherwise prepared upon the predetermined sizes. The menu preparation is such that when a sheet of any of the predetermined sizes is registered within its corresponding interior corners of the recess there obtains a constant (X, Y) offset between a selected point of reference upon the tablet, such as the origin, and a selected point of reference upon the menu. Such automatic constant offset with registration frees the operator of the digitizer from manually instructing the applications software as to the exact location of the menu.
