PURPOSE:To speed up processing at the time of correction, to reduce the titled device at its size and to improve its reliability by forming a storage area for storing data status and collecting time status and centralizing data collection and data correction. CONSTITUTION:When a certain data in a data storage device 5 is to be corrected, a flag indicating the correcting status is set up in a prescribed bit in a data status/collecting time status storage device 22 which corresponds to information necessary for the correction at the input of said information. The flag is detected by a data collection correcting device 21 and the data at the correction time are corrected. If arithmetic processing is necessary at the correction, a data collection arithmetic formula stored in a data collection arithmetic formula storage device 2 is used. Since the device 22 is provided and the data collection and data correction are centralized, the processing and the time of correction can be speeded up, the device can be reduced at its size and the reliability can be improved. |
