Summary:To provide a communication device, a firmware update system, and a firmware update method that easily prevent repeated rewriting of firmware for an apparatus that has a local communication function but does not have a wide-area communication function.SOLUTION: In a firmware update system, a communication device 11 including a local communication unit 30 for communicating with an apparatus 10 and a storage unit 32 for storing firmware for an apparatus operates so that it is not activated as an external storage terminal from the apparatus or the firmware is invisible from the apparatus when it is determined that a history of being activated/deactivated as the external storage terminal by the apparatus is a predetermined sequence set in advance.SELECTED DRAWING: Figure 2 【課題】局所通信機能は備えるが広域通信機能を備えない機器に対して、ファームウェアの書き換えの繰り返しを、容易に防ぐ通信装置、ファームウェア更新システム及びファームウェア更新方法を提供する。【解決手段】ファームウェア更新システムにおいて、機器１０と通信する局所通信部３０と、機器用のファームウェアを記憶する記憶部３２と、を備える通信装置１１は、機器により外部記憶端末として活性化・非活性化された履歴が、あらかじめ設定された所定のシーケンスであると判定した場合は、機器から外部記憶端末として活性化されない、もしくはファームウェアが機器から見えないように動作する。【選択図】図２
