INFORMATION PROCESSOR

PURPOSE:To attain the stop of a data processing at a desired screen by providing a keyed content deciding part, detecting the stop of the keying after the continuous keying, and clearing residual key data in a buffer. CONSTITUTION:When the same key is continuously pounded in a set time cycle by an input device 1, a keyed content deciding part 5 starts to supervise a keying action, thereafter, when the keying is interrupted for the set time, a user regards that a data processor 3 trying to stop the further redundant processing, he clears all the key data left in a buffer 2 by the detection of the stop of the keying. With this constitution, as the result of the continuous keying of the user, even if a key code is left in the buffer 2, and the user stops the keying at his desired screen, the buffer 2 is cleared, and the data processing is stopped in his desired condition.
