Abstract

PURPOSE: To provide the repeat function only to the specific key, by deciding the necessity for the repeat action through the CPU in case both the repeat key and the key on the scan type keyboard are pushed at one time.
CONSTITUTION: With a simultaneous push of the repeat key switch 26 and the scan type keyboard 21, the CPU23 knows that the key is pushed by the interruption request given from the keyboard control LSI. Then the CPU23 decides the necessity for the repeat action. And in case the repeat action is decided necessary, a process same as the key-in action is carried out with the repeat frequency. Then a repeat process is carried out with the frequency given from outside. Thus the repeat function can be provided only to the specific key switch of the scan type keyboard.
