[Claims for Utility Model Registration] Key code storage means for sequentially storing key codes corresponding to a plurality of keys according to a predetermined key operation order; and storing the key code each time a key operation is performed. A reading means for sequentially reading out the key codes stored in the means, and wiring of the key by detecting a match or mismatch between the key code read by the reading means and the key code corresponding to the operated key. A key inspection device comprising: inspection means for inspecting a state; and notification means for notifying a key wiring abnormality when a discrepancy is detected by the inspection means.
