リント基板故障箇所表示装置を提供できる。As is apparent from the above embodiments, according to the present invention, by providing the numbers or symbols indicating the sections in the horizontal and vertical directions of the end portion of the printed circuit board, it is possible to prevent the occurrence of a failure. Since it is decided to display the failure point in the area, the service person will recognize the failure point in the form of an area on the printed circuit board, and will search for the circuit part number in a range that is considerably narrower than the entire conventional printed circuit board. As a result, it is possible to provide an inexpensive printed circuit board failure point display device capable of promptly finding a failure point.

基板故障箇所表示装置を提供できる。Further, in addition to the above, by providing numbers or symbols indicating sections in the horizontal and vertical directions at the end portions of the electric circuit diagram showing the electric circuit configured on the printed circuit board, a failure occurs. Since it was decided to display the failure point in the electric circuit diagram in the area when it was used, the service person would recognize the failure point of the electric circuit in the form of the area on the electric circuit diagram, rather than the entire conventional printed circuit board. It is possible to provide a printed circuit board failure point display device in which a failure point can be promptly found and repaired by searching for a circuit part number within a considerably narrowed range.
