Abstract:
A droplet discharge head includes circuit boards each mounted with one or more nonvolatile memories. The nonvolatile memories are configured in a data-rewritable manner and are used to store written data even when power is turned off. The nonvolatile memories have a write-protect function. One or more of the nonvolatile memories are set to write inhibition state and the write inhibition state is fixed. One or more of the remaining nonvolatile memories are set to rewritable state.
