PURPOSE:To refer to a table with a CPU, to identify the head address of an area designated by an area identifier and to execute a necessary processing by providing the table, in which the area identifier and the address are stored, at a memory area. CONSTITUTION:At respective designated areas 41-4n, only one record is stored. A CPU 2 to receive an AID 5 from a device 11 recognizes the head address of the area 4 designated by the AId 5 by referring to a table 8, and thereafter, reads the prescribed address of an identifier 7 to show the length of information. After the information only shown by the identifier 7 is read, it is sent to the device 11. The CPU 2 searches the head address of the area 4 by referring to the table 8. Thereafter, for the information in the area 4 only the value to subtract 1 from an R.NO is checked (an address 9 of the information shown by the R.NO is searched based upon the identifier 7) and the information shown by the R.NO is erased. |
