<p>PURPOSE:To unnecessitate stopping a main control device and increasing storage capacity when a program is changed and added by storing plural writing/erasing programs and a card discriminating program in a common memory of a flash memory in a master card. CONSTITUTION:The main control device 9 is started by an operator, a card class discriminating program 13 is read out from a common memory 3 of a master card 1 by a read-out means 50, and stored in a RAM 53. Next, a card class code 21 is read out from a slave card 17. A writing/erasing program corresponding to the code 21 is retrieved in the memory 3. A second writing/ erasing program 15 is read out from the memory 3. Next, the information stored in a common memory 19 and an attribute memory 20 is erased by a means 51. Stored information of an operational program 6, common data 7 and the attribute memory 20 is erased. A first to third writing/erasing program 14 to 16 are duplicated. Verifying check is performed by a means 54. When it is correct, a signal of normal duplication is outputted from the card 1 to the card 17 by an output means 56.</p> |
