Abstract

PURPOSE:To reduce the processing load for a data processing unit by carrying out the scan and the reception control only when a key operation part or a keyboard unit is operated and after the data processing jobs carried out by those key operations become idle. CONSTITUTION:When the keys are operated at a key operation part, a microcomputer CPUS scans the key operation part and receives the key operation information as long as a keyboard unit 3 is not processing data. Then keys are operated via the unit 3 and therefore the unit 3 is controlled by the processor CPUS as long as the key operation part is not processing data. At the same time, the information on the key operations of the unit 3 are received. Thus the data processing load is reduced for a data processing unit 6 by carrying out the data processing only when the keys are operated at the key operation part with no usual accesses given to the key operating part.
