PROBLEM TO BE SOLVED: To provide a business machine operation part which predicts the user's way of usage, asks from the machine side what the user desires to do, and automatically changes operations so as to follow the user's habit. SOLUTION: The business machine operation part has a function for counting button signals from a first button (number button 2) or a specific sensor, and a function for counting button signals generated by the depression of the second button (sorting button 4) after counting the preceding button signals. When the number of the first button signals becomes equal to or greater than a predetermined number and the number of times of the second button signals arithmetically obtained by the above number of times of button signals reaches a prescribed value or exceeds it, a message requiring a judgment as to whether the 2nd button is to be pressed is issued when a machine user presses the first button, and a machine operation according to the judgment is carried out. |
