<p>PURPOSE:To grasp the constitution of a packed card by transmitting the code read address information, the card name rough sorting code information, and the multi-identification address information via a master card and at the same time returning the card name fine sorting code information and the multi-sheet code information via a slave card respectively. CONSTITUTION:A master card produces the code read address information, the card name rough sorting code information, and the multi-identification address information as the address signals so as to check the constitution of a slave card via a check address signal production/transmission means. These address signals are sent to the slave card via a bus line. Then an answer data signal reception/identification means receives the card name fine sorting code information and the multi-sheet code information sent back from the slave card as the data signals via a bus line based on a check address signal and then identifies the type and the name of the slave card as well as the present number of cards of the same type based on a data signal. Thus it is possible to grasp the constitution of a packed card without changing a standard bus.</p> |
