PURPOSE:To easily visually recognize the functions of keys by an operator, by displaying the keyboard display data sent by a data processor on a display means provided at least at every part of the keys. CONSTITUTION:A keyboard display data reception means 3B receives the keyboard display data transmitted from the data processor 4, and sets it on a key/display data correspondent table 3D, and starts up a keyboard display means 3C. The display means 3C displays each display data on the display means (liquid crystal display plate) D1-Di corresponding to respective key of the keys A1-Ai on a keyboard part 2, referring to the key/display data correspondent table 3D. The operator who inputs data to the data processor 4 from the keyboard part 2, after confirming a display content being displayed on the display means D1-Di on the keyboard part 2, depresses a prescribed key out of the keys A1-Ai. An inputted data is transmitted to the data processor 4 via a key input processing means 3A.
