PURPOSE:To realize all transactions with use of a bankbook only by reading and discriminating gradationally intrinsic image data recorded on a transaction medium and then recording gradationally those image data as journal data when a transaction is satisfied. CONSTITUTION:A bankbook/journal printer device 17, a magnetic reader/writer device 18, an image reader device 19, and a bankbook page-returning device 20 are connected to a bankbook reader/printer device control part 16. The device 19 reads gradationally the intrinsic image data on a bankbook. Then it is decided whether the bankbook is equal to a transaction-enable medium or not based on the mean gradation level value and the image existing range area of the read image data. When a transaction is satisfied, the image data are gradationally recorded as the journal data by the device 17. |
