Circuit Board, Image Forming Apparatus, And Method Of Managing Reuse Information Of Circuit Board

摘要

A circuit board includes a main part on which a processor is mounted, a cut part to be cut off from the main part at a cut section before the board is reused, and a conductor pattern wired through the cut part via the cut section and to be cut off into a plurality of patterns at the cut section as the cut part is cut off. The processor detects a difference in signal level between a level of a signal output from the conductor pattern before the cut part is cut off, and a level of the signal output from the conductor pattern after the cut part is cut off, to determine a number of times the board is reused.
