PURPOSE:To surely execute the change of numerical values in a short time even if the drastic change of numerical values is requested to be executed by making the changing quantity of displayed numerical values small within the range of the displayed numerical value previously determined and making the changing quantity of the displayed numerical value large out of said range. CONSTITUTION:The title device possesses a key 1, an input device 2 which reads the actuation of the key 1 and executes arithmetic processing and a displaying member 3 which executes the corresponding display of the numerical value according to a signal from the input device 2. The changing quantity of the numerical value per unit time within the prescribed range of the numerical values previously determined by the input device is set in different value from that out of said range. For example, out of the set range, the numerical values change ten times as fast as within the set range, so that the change can be executed in a short time. And since the change of the numerical value is executed one by one within the set range, it is necessary to stop pushing down the key at the time of confirming a numerical value. Thus, the numerical values are quickly changed in an unnecessary part, so that the time for changing magnification can not be needed and also a specified value can be surely obtained. |
