Abstract

PURPOSE: To increase an input speed by reducing keying-in operation in the number of times while improving the efficiency of input operation, by using foot switches to change character and symbol modes in addition to shift keys.
CONSTITUTION: Keyboard main frame 1 is provided with foot switches 2a and 2b for shift keys. With key 1a on keyboard body 1 pushed, signals are generated to X and Y axes. Those signals are inputted to code generator 3, where they are converted into fixed codes of this system. At this time, two foot switches 2a and 2b controlling the mode and shift of characters are connected to this code generator 3 and character modes are changed and control over a shift is exercised by stepping on those foot switches.
