特徴とするキーボードシフト制御回路。On the keyboard used to enter data,
a shift key that indicates a kana symbol shift state; a circuit that detects a pressed state when the shift key is pressed; a circuit that generates a code corresponding to the shift key after detection by the detection circuit; and a circuit that decodes the code. and a flip-flop that is reset by the output of the detection circuit and reset by a code generated by pressing a key switch other than the kana symbol shift key, and the shift state set by pressing the kana symbol shift key is fixed. A keyboard shift control circuit characterized in that it is retained only for the number of keystrokes input.
