PURPOSE:To easily and accurately manage necessary information such as failure history and service information by providing a non-volatile memory for storing history information and an output part in the peripheral circuit of a CPU and connecting an external storage device to the output part. CONSTITUTION:The CPU 1 is provided with an operation panel 2, a sensor 3, the non-volatile memory 4 and the output part 5 as the peripheral device. Then, the external storage device 6 such as a floppy disk drive, etc., can b connected to the output part 5. Therefore, the content of the memory 4 is outputted to the device 6 and recorded on a recording medium, thereby eliminating the error and the omission of writing made by a service-man in the case that service is performed by using a service management card, etc. Thus, the history information such as the failure history is more accurately managed. |
