Claims

[Scope of Claim for Utility Model Registration] (1) A ROM board-cut ROM writer that writes data all at once to a group of read-only memories (hereinafter referred to as ROM) mounted on a printed circuit board, ROM without erasing
an erase check means for confirming erasure of the ROM contents; and an automatic erase means for automatically erasing the ROM using an unerased signal output when the erase check means detects that the ROM contents are not erased. and automatic ROM cut-off means for cutting off the ROM in response to an erase completion signal outputted when erasing by the above-mentioned automatic erase means ends. (2) The ROM writer according to claim 1, wherein the automatic ROM cutting means checks the ROM erase state without completing it, and executes the ROM cutting of the designated area upon completion of the erase process. .
