摘要

Circuit board coordinate position symbols of respective electronic components arranged on a microcomputer board based on an X-axis direction and a Y-axis direction of the microcomputer board are displayed in the vicinity of reference numbers or component symbols representing the respective electronic components and displayed on a microcomputer circuit diagram. Circuit diagram coordinate position symbols of respective reference numbers or component symbols representing the respective electronic components and displayed on the microcomputer circuit diagram are displayed in the vicinity of the reference numbers or component marks corresponding to the respective electronic components and displayed on the microcomputer board. Front or rear identification symbols identifying a front surface or a rear surface of a video and voice processing board, which is a both-sided mount board, are added to the respective circuit board coordinate position symbols on the circuit diagram of the board and displayed on the circuit diagram.
