PURPOSE:To make a keyboard easy to use for even a beginner, by providing two shift keys which turns clockwise and counterclockwise in a multi-stage keyboard for computer sequentially shifting in rotary mode. CONSTITUTION:On a keyboard of the JIS key arrangement standard, one shift key 2 is depressed, then shifted clockwise, and lamps 4a-4d at are illuminated at the shifted position of a display device 4. When another shift key 3 is depressed, shifted counterclockwise. In this system, two-stage shift can be made by alternately depressing the shift keys 2 and 3 and in the case that a numeral is superimposed on a Kana (Japanese syllabary), the display is restored to the original Kana by depressing a shift key 2, a character key 1 and a shift key 3. |
