Abstract

PURPOSE:To give priority to the storage processing for key data during key operation by detecting the presence of flag data in a key input buffer and then by inputting key data which correspond to operated keys to the key input buffer. CONSTITUTION:In a step S1 in a key input stand-by state, the contents of digits K0 and K1 of a K register are discriminted; and when they show[0]s, no key data is considered to be present to transfer the control to a step S2 and the data of a storage part is displayed to return the step S1. When the digits K0 and K1 are not[0]s, key data which corresponds to one key is considered to be present; and transfer the contents of the K0 and K1 to an Y register in a step S3, and flag data 15 is set to the digit K1 in a step S4. The digits K0, and K2-K11 of the K register have key data and in a step S5, the K0-K11 are shifted down by one digit to transfer the flag data to the K0. In a step S6, those data are further shifted down by one digit and in a step S7, registration and arithmetic processing which correspond to the key data in the Y register are performed, thereby returning the control to the step S1.
