<p>PURPOSE:To improve the reliability and also the efficiency by starting a reset control means when a reset button is operated consecutively twice or more so as to prevent mis-operation of the reset button. CONSTITUTION:The content of a data buffer 6 is checked when the reset button 1 is depressed once and if an unprocessed reception data is still left, an on-line display lamp 10 is applied with flashing and if no unprocessed reception data exists in the buffer 6 on the other hand, the buffer is cleared. When the button 11 is depressed twice or more, it is discriminated that no mis-operation exists and the buffer is erased independently of it whether or not any unprocessed reception data is left in the buffer 6. When a button except the button 11 is depressed during the flashing of the lamp 10, it is discriminated that it is possible that the preceding depression of the button 11 is done in error and then no reset sequence is started.</p> |
