Abstract
A coordinate detecting apparatus with a display unit of a type having a separated control unit constituted for the purpose of improving the handling facility of the coordinate detecting apparatus with the display unit, lowering the frequency for transferring data about the contents to be displayed, enabling the circuit for the display control means to be freely designed and also enabling the coordinate detecting apparatus to be connected to an existing computer body. The coordinate detecting apparatus with the display unit is supplied with power from a power source for a control unit, data about the contents to be displayed is supplied from the control unit to the coordinate detecting apparatus with the display unit via one integrated cable while being compressed to form a graphic control signal, the data about the contents to be displayed is restored in the coordinate detecting apparatus with the display unit and the aforesaid function is given to the interface board.
