PURPOSE:To immediately correspond with a simple operation which changes machine language of sub-bank, even if the operation of an input and output device changes, by linking the program of the sub-bank to that of common area and main bank. CONSTITUTION:Each bank consists of main banks BANKO-n and sub-banks SBKO-n. A common area CAR is provided with a table designating sub-banks SBKO-n and bank switches SW1-2 which logically switch each sub-bank and the said main banks. Thus, if it is required to read out the program of the sub-banks, the table is indexed as to the number of the sub-banks and since the address is common by only knowing the number, the control of the printer B can be made immediately by switching the selector bank switch SW2. |
