摘要：
A marking device for marking a sheet mounted on a digitizer board includes a measuring coil inductively coupled to the digitizer board when the coil is operatively positioned relative to the board. A switch on the marking device is operable to cause current pulses to be applied to the conductors on the digitizer board producing magnetic flux which couples the conductors on the board to the coil. A marker on the marking device is responsive to operation of the switch for marking a thermosensitive sheet on which the measuring coil is placed thereby marking on the sheet the position of the marking device when the switch was closed.
