Abstract

PURPOSE: To improve the manipulation of key-input operation by securely performing the print-out processing of data written in a key-input buffer register and then by eliminating the need to input the data again.
CONSTITUTION: On the basis of an input signal from keyboard 2 of input-output part 4, CPU1 performs various kinds of arithmetic processing to exercise operation control over memory part 3 and input-output part 4. This memory part 3 is provided with ROM5 stored with a program for the interruption processing of key inputs from keybared 2 and a main program for various kinds of processing, and RAM6 stored with data processed in various ways, and this RAM6 is composed of key over-flag 7, key-input buffer register 9, and print buffer register 10. Then, a check on wheter resitater 9 is full of data inputs is made to inhibit and key input from being supplied to register 9, and in this state, data in register 9 are printed out securely.
