Abstract

PURPOSE:To make the realization of the same function as that of the shift key of a mechanical typewriter possible with an electronic type keyboard device by providing plural character keys, and a shift keys, as well as respective specific selection signal output means and an input control part. CONSTITUTION:Plural character keys 11, a shift key 20 assigning one of two kinds of character with respect to the respective keys 11, and a selection signal output means which outputs a mode selection signal after the end of the operation of said key 11 if the key 11 has been operated when the depression operation or the releasing of the depression operation of the key 20 is detected or immediately if the key 11 hss not been operated are provided. Further, an input control part 13 which makes inputting of the 1st kind of character data possible when the mode selection signal by the depression operation of the key 20 is outputted and controls the 2nd kind of character data inputtable when the mode selection signal by the releasing of the depression operation of the key 20 is provided.
