Furthermore, when receiving no door opening/closing command from the main control device 131 after a prescribed time elapses from the confirmation of the opening/closing operation of the front door 12, the display control device 111 notifies, to the outside, of a possibility that the main control device 131 has been replaced. Therefore, even if the main control board 131 has been replaced by a fraudulent one, secondly notification can be executed when the front door 12 is operated so as to be openable and closable to make the outside notify the possibility that the main control device 131 has been replaced. |
