Abstract

PURPOSE:To improve the operability in data input by displaying a shifting con- dition to make the movement of operator's eyes easy at setting the shift stage and at operating a input key. CONSTITUTION:When the shift stage corresponding to the item to which the operator wants to input, for example, is the 3rd stage, the input key K3 having the item corresponding to the 3rd stage is depressed. Then, the C2 input of a coincidence circuit 63 is set to logic ''1'' and the D2 input is set to logic ''0'', respectively. In this case, the J input of FF33 becomes ''1''. Then, the FF33 is set by the fall of a clock signal 17 at that time and only a lamp 3 is lighted continuously on a input keyboard 3. Simultaneously, and AND gate G7 is energized to make the clock signal 17 pass and the signal is fed to the 2nd frequency dividing circuit 91. A frequency dividing ratio N2 of the 2nd frequency dividing circuit 91 is set larger than a frequency dividing ratio N' of a 1st frequency dividing circuit 41. By means of this, confirmation of the shifted items corresponding to the depressed input key can be performed by prolonged lighting duration of lamps S1-S4.
