PURPOSE:To improve both the operability and the efficiency of a transaction requiring the control of types of money, by displaying a desired picture of the type of money concurrently with a transaction picture without deleting the display data on the transaction picture. CONSTITUTION:In a normal mode a transaction picture is displayed on the entire area of a display part. A money type picture display detector 6 detects a chance for display of the money type picture and turns on a money type picture designation control data 11. A screen data forming device 7 detects the ON state of the data 11 and supplies the money type screen data 10 through a money type picture storage 5. Then a valid display area for the transaction picture data 9 is obtained out of the display area for the money type picture. The transaction data corresponding to the valid display area is produced with compression. This produced data is synthesized with the data 10 into the picture display data 12. Then the data 12 is displayed at a display part 8. |
