Abstract

PURPOSE: To easily perform the input indication for required function, by the classification of mutually related functions, selecting the classified function and indicating required function among the function group selected.
CONSTITUTION: The key group FS is constituted so that the timing signals T1WT6 can be fed to one end of each key, and another end of the keys is connected to the common terminal CT of the slide switch GS. This switch GS feeds the timing signals T1...T6 obtained via the key operated with the key group FS to either one of the terminals LT1...LT4. For example, when the switch GS selects the term A, the signals T1...T6 are fed to the terminal LT1 and when the term B is selected, the signals are fed to the terminal LT2. The timing signal is shared into four and the function is designated by detecting the signals T1...T6. Thus, the input indication of required function can be made easily.
