Abstract
A Cartesian coordinate tracing table for entering a program into a memory of an automatically controlled machine. The tabel has guide bars extending in the X and Y directions. Two rotary generators which are responsive to movement of a cursor in the X and Y directions generate electrical signals for transmission to a memory. One rotary pulse generator is mounted on a carriage movable along the guide bar extending in the X direction. The other rotary pulse generator is mounted on a cursor slidable along the guide bar extending in the Y direction which in turn is mounted on the carriage. Each rotary pulse generator includes a rotatable shaft having a driving roller which contacts a guide bar to provide the driving force to the generator.
